# AMD Ryzen 3 8440U + NVIDIA GeForce RTX 4070 Mobile

This laptop pairing combines a 4-core Zen 4 mobile processor with a high-end Ada Lovelace GPU, landing at the 72nd percentile overall among all system combinations. The RTX 4070 Mobile is the dominant component here, sitting at the 73rd GPU percentile, while the Ryzen 3 8440U trails at the 70th CPU percentile. The result is a system where GPU-bound workloads excel, but CPU-heavy tasks reveal a clear bottleneck. No measured FPS rows exist for this exact combination — the FACT PACK contains no measuredFps data — so all frame rate discussion below is estimated from the benchmark scores.

Usage Scenarios

High-refresh gaming: The RTX 4070 Mobile's PassMark G3D score of 19587 places it at the 73rd GPU percentile, essentially tied with the AMD Radeon RX 6700 XT (deltaPct 0%). That level of rasterization performance is well-suited for 1080p high-refresh gaming, where the GPU can push frame rates beyond 144 Hz in most competitive titles. At 1440p, the 8 GB GDDR6 memory on a 128-bit bus with 256.0 GB/s bandwidth will sustain high settings, though the 4-core CPU may cap minimum frame rates in CPU-bound scenes.

Streaming: The GPU's 144 tensor cores and 36 RT cores provide hardware-accelerated encoding and AI features, but the CPU's modest PassMark multithread score of 12805 means software encoding while gaming could strain the system. The Radeon 740M integrated graphics on the CPU offers a fallback display output, but the RTX 4070 Mobile's NVENC-class encoder (implied by Ada Lovelace architecture) is the better choice for streaming. Expect to rely on GPU-side encoding to keep the 4-core/8-thread CPU free for game logic.

Video editing: The Cinebench R23 multicore score of 10884 (70th CPU percentile) indicates acceptable but not exceptional rendering performance for timeline previews and exports. The GPU's OpenCL score of 109197 accelerates effects and color grading, while the 8 GB VRAM handles 4K timelines with moderate complexity. Data compression score of 146273 in PassMark suggests reasonable handling of codec-heavy workflows, but the 8 MB L3 cache and 4 cores will show strain on long 4K exports.

3D rendering: The RTX 4070 Mobile's FP32 throughput of 15.62 TFLOPS and 4608 shading units make it a capable GPU renderer, with PassMark GPU compute score of 8399 confirming strong compute performance. CPU-based rendering with the Ryzen 3 8440U will be slower — the Cinebench R20 multicore score of 4571 is modest — so hybrid rendering pipelines that offload to the GPU will be far more productive. The 36 RT cores provide hardware ray tracing acceleration, though the 4-core CPU may bottleneck scene preparation.

Software development: The single-core Cinebench R23 score of 1536 and PassMark single-thread score of 3648 indicate responsive compilation for small-to-medium projects. The 4 cores and 8 threads handle parallel builds adequately, but large codebases will expose the 70th CPU percentile ceiling. Data encryption score of 8012 and extended instructions score of 11059 in PassMark suggest solid cryptographic and SIMD performance for security-focused development tasks.

Student and office work: The 28 W TDP CPU with 4 nm process efficiency delivers strong battery-friendly performance for everyday productivity. PassMark integer math score of 37468 and floating point score of 23017 cover spreadsheet, document, and browsing workloads comfortably. The Radeon 740M integrated graphics provides a low-power display solution for basic tasks, while the RTX 4070 Mobile remains available for heavier graphical demands.

FAQ

Q: How does the Ryzen 3 8440U compare to its closest CPU rivals?

A: The Ryzen 3 8440U's average benchmark score of 16663 is 0.5% below the Intel Core Ultra 5 115U (16753), 0.6% below the Intel Core i5-1235U (16770), 1% below the AMD Ryzen 3 7335U (16827), and 1.1% below the Intel Core i3-12100E (16853). All four rivals are within a narrow 1.1% band, putting the 8440U at the bottom of this peer group.

Q: What is the GPU's performance tier relative to desktop graphics cards?

A: The RTX 4070 Mobile's average benchmark score of 27435 places it at the 73rd GPU percentile. It is exactly tied with the AMD Radeon RX 6700 XT (deltaPct 0%), 0.5% below the NVIDIA GeForce RTX 3090 (deltaPct -0.5%), 1.1% above the NVIDIA RTX PRO 4000 Blackwell (deltaPct 1.1%), and 1.5% below the AMD Radeon Pro Vega 20 (deltaPct -1.5%).

Q: Does the CPU bottleneck the GPU in gaming?

A: Yes, the 4-core/8-thread CPU with a 70th CPU percentile is significantly weaker than the GPU's 73rd GPU percentile. In GPU-bound titles at high resolutions, the RTX 4070 Mobile will be the primary performance driver, but at lower resolutions or in physics-heavy games, the CPU's PassMark physics score of 685 and multithread score of 12805 will limit frame rates.

Q: What memory bandwidth does the platform support?

A: The CPU supports dual-channel DDR5 memory with a bandwidth of 89.6 GB/s. The GPU has its own 8 GB GDDR6 memory on a 128-bit bus providing 256.0 GB/s of bandwidth, which is separate from the system memory.

Q: Is this a desktop or laptop build?

A: The build class is "laptop." The CPU uses AMD Socket FP7, the GPU is classified as "IGP" slot width with portable device dependent display outputs, and the power connector is listed as "None," all consistent with a mobile platform.

Q: How does the CPU's single-thread performance compare to its multicore performance?

A: The Cinebench R23 single-core score of 1536 is strong relative to the multicore score of 10884, which is only 7.1x the single-core figure despite having 8 threads. This indicates the 4-core design scales reasonably but the overall multicore ceiling is low due to core count.

Q: What is the combined system percentile?

A: The combined percentile is 72, which is between the CPU's 70th and GPU's 73rd percentile. This suggests the overall system performance is weighted slightly toward the GPU's strength.

Balance and Bottleneck

The performance asymmetry between the CPU and GPU defines this build's character. The RTX 4070 Mobile at the 73rd GPU percentile is the clear performance leader, while the Ryzen 3 8440U at the 70th CPU percentile lags behind. The 3-percentage-point gap might seem small, but the workload implications are substantial.

In GPU-bound scenarios — gaming at 1440p or higher, GPU rendering, video effects processing — the RTX 4070 Mobile's 19587 PassMark G3D score will be the primary driver, and the CPU's relative weakness will be masked. The GPU's FP32 throughput of 15.62 TFLOPS and 244.1 GTexel/s texture rate provide ample headroom for resolution scaling. However, in CPU-bound workloads — physics simulation, game logic, compilation, data compression — the 4-core CPU's PassMark multithread score of 12805 and Cinebench R23 multicore score of 10884 become the limiting factor.

The PassMark physics score of 685 is particularly telling. This measures CPU physics computation, which is critical for game engines. A score in the 600s range suggests that physics-heavy scenes will bottleneck even when the GPU has headroom. Similarly, the PassMark find prime numbers score of 43 indicates weak integer-heavy single-thread workloads, which affects certain legacy applications and specific game engines.

The memory hierarchy also shows imbalance. The CPU's 89.6 GB/s DDR5 bandwidth is modest, while the GPU's 256.0 GB/s GDDR6 bandwidth is generous. This means data-heavy workloads that require frequent CPU-GPU transfers will be limited by the CPU's memory throughput. The cache structure — 64 KB L1 per core, 1 MB L2 per core, 8 MB shared L3 — is typical for a 4-core design, but the shared L3 is small compared to higher-core-count rivals.

Thermal and power constraints also shape the balance. The CPU's 28 W TDP and the GPU's 115 W TDP mean the GPU consumes over four times the power budget. In a laptop chassis, this can lead to thermal throttling under sustained load, particularly if the cooling solution is shared. The GPU's 5 nm process and 22,900 million transistors on a 188 mm² die generate significant heat, while the CPU's 4 nm process with 20,900 million transistors on 137 mm² is more efficient.

The practical bottleneck depends on the workload. For gaming, the CPU will cap frame rates at 1080p in CPU-heavy titles, while the GPU will be the limit at 1440p in visually demanding games. For productivity, the CPU's 4 cores will limit parallel rendering, while the GPU accelerates compute-heavy tasks. The system is best balanced when the GPU is the primary compute engine and the CPU handles orchestration.

Who Should Build It

The primary audience is gamers who prioritize GPU performance over CPU grunt. The RTX 4070 Mobile's 73rd GPU percentile, tied with the desktop RX 6700 XT, delivers smooth 1080p high-refresh and capable 1440p gaming. At 1080p, the GPU can push well beyond 144 Hz in esports titles, while at 1440p it handles demanding AAA games at high settings. The 8 GB GDDR6 memory is sufficient for current titles at these resolutions.

Content creators who rely on GPU-accelerated workflows will find value here. The 15.62 TFLOPS FP32 performance and 109197 OpenCL score support video editing, effects rendering, and GPU-accelerated 3D work. The 36 RT cores provide hardware ray tracing for 3D artists using DXR-enabled applications. However, creators who need CPU-heavy rendering, such as software engineers compiling large codebases or 3D artists using CPU renderers, will find the 4-core CPU limiting.

Students and professionals who need a mobile workstation with strong graphics for visualization, CAD, or data science will benefit from the GPU's compute capabilities. The CPU's 70th percentile handles standard productivity with headroom, while the GPU accelerates CUDA-accelerated workloads in scientific computing, machine learning inference, and financial modeling. The 28 W CPU TDP and 115 W GPU TDP make this a performance laptop that requires a substantial power adapter but is not as power-hungry as desktop replacements.

Small business workstations that run GPU-accelerated applications — video conferencing with background effects, design software, or analytics dashboards — will perform well. The combination of 4 fast Zen 4 cores and a high-end mobile GPU covers most business graphics needs. However, teams running heavily multithreaded server-side workloads should look at higher-core-count CPUs.

The system is less suited for developers working on massive parallel builds, data scientists training large models on CPU, or gamers targeting maximum frame rates at 1080p in CPU-bound titles. In those cases, the 4-core CPU becomes the clear bottleneck, and the GPU's power is partially wasted.

Benchmark Performance

The CPU's average benchmark score is 16663, placing it at the 70th percentile of all CPUs. Its nearest rival is the Intel Core Ultra 5 115U at 16753 (0.5% higher), followed by the Intel Core i5-1235U at 16770 (0.6% higher), the AMD Ryzen 3 7335U at 16827 (1% higher), and the Intel Core i3-12100E at 16853 (1.1% higher). This places the 8440U at the bottom of a tight 1.1% band, meaning the performance difference between these chips is marginal.

The GPU's average benchmark score is 27435, at the 73rd percentile of all GPUs. It matches the AMD Radeon RX 6700 XT exactly (deltaPct 0%), sits 0.5% below the NVIDIA GeForce RTX 3090, 1.1% above the NVIDIA RTX PRO 4000 Blackwell, and 1.5% below the AMD Radeon Pro Vega 20. This is a high-end mobile GPU that rivals desktop cards from the previous generation.

The combined system percentile is 72, reflecting the slightly stronger GPU relative to the CPU. In Cinebench R23, the CPU scores 10884 multicore and 1536 single-core — a ratio of 7.1x, which is typical for a 4-core/8-thread part. The Cinebench R20 scores of 4571 multicore and 645 single-core, and R15 scores of 1097 multicore and 154 single-core, follow the same pattern.

PassMark results show a mixed profile. Multithread score of 12805, single-thread score of 3648, integer math of 37468, floating point math of 23017, data compression of 146273, data encryption of 8012, extended instructions of 11059, physics of 685, and random string sorting of 17725. The physics score is notably low relative to other metrics, indicating weaker performance in physics simulation tasks.

For the GPU, PassMark G3D of 19587 and G2D of 763, with compute score of 8399. Geekbench OpenCL of 109197 and Vulkan of 108367 show strong compute performance across APIs. DirectX tests show 116 (DX10), 179 (DX11), 85 (DX12), and 223 (DX9), while the GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The combined picture is a system where the GPU is the star performer at the 73rd percentile, the CPU is a competent but not exceptional partner at the 70th percentile, and the overall build sits at the 72nd percentile. This is a balanced-enough pairing for GPU-dominated workloads, but the CPU will be the limiting factor in multithreaded tasks.

Gaming Performance

No measured FPS rows exist for this exact combination — the FACT PACK contains no measuredFps data — so all frame rate figures below are estimates derived from the benchmark scores. The GPU's PassMark G3D score of 19587, tied with the desktop Radeon RX 6700 XT, suggests strong 1080p and 1440p performance. At 1080p ultra settings, most AAA games should run between 100-140 FPS, while esports titles can exceed 200 FPS. At 1440p ultra, expect 70-110 FPS in demanding titles, with lighter games reaching 140+ FPS.

The CPU's single-thread score of 3648 in PassMark and 1536 in Cinebench R23 will support high frame rates in GPU-bound scenarios. However, in CPU-bound games — particularly those with heavy physics or simulation elements — the 4-core CPU will cap frame rates at around 90-120 FPS in the most demanding scenes. The PassMark physics score of 685 is a warning that complex physics interactions will cause frame rate dips.

At 1080p, the GPU will often be underutilized because the CPU cannot feed it fast enough in many titles. This is especially true for competitive shooters where high FPS matters. At 1440p, the GPU becomes the primary limiter, and the CPU has more headroom to keep up. At 4K, the 8 GB VRAM and 256.0 GB/s bandwidth will be the constraints, with frame rates dropping to 40-60 FPS in the most demanding titles.

Ray tracing performance, supported by 36 RT cores, will be playable at 1080p with DLSS enabled, but at 1440p with ray tracing ultra, frame rates will drop to 50-70 FPS. The 15.62 TFLOPS FP32 and 81.36 GPixel/s pixel rate provide solid rasterization, but the 128-bit memory bus limits bandwidth-heavy effects like high-resolution textures combined with ray tracing.

CPU Analysis

The AMD Ryzen 3 8440U is a 4-core, 8-thread mobile processor from the 8000 series, built on Zen 4 architecture with the Hawk Point codename. It uses a 4 nm TSMC process with 20,900 million transistors on a 137 mm² die. The base clock is 3.00 GHz with a boost clock of 4.70 GHz, and it has a 28 W TDP.

The cache hierarchy is 64 KB L1 per core, 1 MB L2 per core, and 8 MB shared L3. Memory support is dual-channel DDR5 with 89.6 GB/s bandwidth. The integrated Radeon 740M graphics provides a fallback display solution. PCIe support is Gen 4 with 14 lanes from the CPU.

The benchmark scores place this CPU at the 70th percentile, with an average score of 16663. Its rivals are all within 1.1%, meaning the 8440U is competitive but not superior. The Cinebench R23 multicore score of 10884 is strong for a 4-core part, but the 7.1x scaling from single-core suggests diminishing returns from simultaneous multithreading.

In real workloads, the 4.70 GHz boost clock provides responsive single-thread performance for everyday tasks. The PassMark single-thread score of 3648 and Cinebench R23 single-core score of 1536 are competitive for mobile parts, supporting fast application launches and responsive UI. The 4-core design is adequate for office productivity, web browsing, and light content creation, but will struggle with heavily multithreaded workloads.

The 4 nm process efficiency is a key advantage, enabling the 28 W TDP to deliver strong performance-per-watt. This makes the 8440U suitable for thin-and-light laptops where battery life matters. The 20,900 million transistor count is substantial for a 4-core chip, reflecting the integrated Radeon 740M graphics and advanced Zen 4 architecture.

Data compression score of 146273 and random string sorting of 17725 in PassMark indicate solid performance for data processing tasks. The extended instructions score of 11059 supports modern SIMD workloads. However, the find prime numbers score of 43 is low, reflecting weaker integer-heavy single-thread performance in specific algorithms.

Upgrade Path and Platform

The CPU uses AMD Socket FP7, which is a mobile-only socket. This limits CPU upgrades to other FP7-compatible processors, but laptop designs typically have soldered CPUs, so upgrades are rarely possible. The memory support is dual-channel DDR5 with 89.6 GB/s bandwidth, and upgrading to higher-capacity or faster DDR5 modules may be possible if the laptop allows it.

The GPU is a mobile part with an "IGP" slot width, meaning it is soldered to the motherboard. The bus interface is PCIe 4.0 x8, which is standard for mobile GPUs. There is no upgrade path for the GPU in a laptop form factor, so the RTX 4070 Mobile is the final graphics configuration for this system.

The PCIe Gen 4 support with 14 lanes from the CPU provides adequate bandwidth for the GPU and one or two NVMe SSDs. Upgrading storage to a Gen 4 NVMe drive will maximize transfer speeds, though the CPU's lane allocation means the GPU and storage share bandwidth. The GPU's 256.0 GB/s memory bandwidth is fixed.

The CPU has a 28 W TDP and the GPU has a 115 W TDP, totaling 143 W for the core components. The suggested PSU is not listed in the data, but laptop power adapters typically range from 150-200 W for this class of system. The GPU has no power connectors, indicating it draws power from the motherboard, so the laptop's power delivery system is critical.

A sensible next upgrade for this platform would be increasing system memory to the maximum supported capacity, as dual-channel DDR5 bandwidth of 89.6 GB/s benefits the CPU's integrated graphics and overall responsiveness. Adding a high-speed Gen 4 NVMe SSD for game storage is another practical upgrade. However, the core CPU and GPU are fixed, so the platform's longevity depends on whether the workload demands grow beyond the 4-core CPU's capabilities.

Build Overview

This is a laptop build combining the AMD Ryzen 3 8440U (4 cores, 8 threads, Zen 4 Hawk Point, 4 nm) with the NVIDIA GeForce RTX 4070 Mobile (Ada Lovelace, 5 nm, 4608 shading units, 8 GB GDDR6). The combined percentile is 72, placing this system above the majority of configurations in the database.

The CPU sits at the 70th percentile with an average benchmark score of 16663, while the GPU sits at the 73rd percentile with an average score of 27435. The GPU is the stronger component, delivering desktop-class performance tied with the RX 6700 XT and within 0.5% of the RTX 3090. The CPU is a capable but unexceptional mobile processor, at the bottom of a tight 1.1% band with four rivals.

This is a GPU-first build. The RTX 4070 Mobile is the headline component, providing high-refresh 1080p gaming, capable 1440p performance, and strong GPU compute for content creation and professional workloads. The Ryzen 3 8440U is a supporting actor that handles everyday tasks well but will bottleneck the GPU in CPU-bound scenarios.

The system occupies a specific niche: it is a laptop for users who prioritize graphics performance over CPU multithreading. Gamers, GPU-accelerated content creators, and professionals running CUDA-accelerated applications will find this pairing effective. Users who need heavy CPU rendering, massive parallel compilation, or physics simulation will find the 4-core CPU inadequate.

The overall tier is upper-mid-range, at the 72nd combined percentile. The CPU's 70th percentile and GPU's 73rd percentile indicate a system that outperforms most laptops but does not reach the top tier of 8-core CPU + flagship GPU configurations. The platform is modern — Zen 4 CPU, Ada Lovelace GPU, DDR5 memory, PCIe Gen 4 — but the 4-core CPU caps the system's ceiling. For the target user, this is a well-balanced, high-performing laptop. For users needing CPU muscle, it will disappoint.
