# Balance and Bottleneck

The pairing of an AMD Ryzen 3 8440U with an NVIDIA GeForce RTX 4080 Mobile presents an unusually wide performance delta between the two primary components. The CPU sits at the 70th percentile among all processors, while the GPU reaches the 81st percentile among all graphics cards. This 11-percentile gap indicates that the processor will be the limiting factor in most GPU-bound scenarios, particularly at lower resolutions where frame rates are less constrained by the graphics pipeline.

The Ryzen 3 8440U's average benchmark score of 16663 places it within a tight cluster of comparable mobile processors. Its nearest rival, the Intel Core Ultra 5 115U, scores 16753, a difference of only -0.5 percent. The Intel Core i5-1235U trails by -0.6 percent, and the AMD Ryzen 3 7335U is -1 percent behind. The Intel Core i3-12100E rounds out the group at -1.1 percent. This clustering shows that the 8440U is not an outlier in either direction; it sits squarely within the expected range for its class.

The GPU, by contrast, shows a more volatile competitive position. The RTX 4080 Mobile's average benchmark score of 38135 places it near the NVIDIA GeForce MX570 (38299, -0.4 percent) and the RTX 5080 Mobile (38349, -0.6 percent), while it leads the RTX 4070 by 1.3 percent and the Tesla P4 by the same margin. The narrow delta against the MX570 is notable, as that is a far less capable card in real-world terms, but the aggregate score masks the RTX 4080 Mobile's strengths in specific workload categories.

The bottleneck analysis hinges on the CPU's 4-core, 8-thread configuration. With a base clock of 3.00 GHz and a boost of 4.70 GHz, the 8440U can deliver strong single-thread performance when needed. However, its multi-threaded throughput is limited by the physical core count. The Cinebench R23 multi-core score of 10884 and single-core score of 1536 show a ratio of roughly 7:1 between multi-threaded and single-threaded performance, which is typical for a 4-core part with simultaneous multithreading.

In gaming workloads, the RTX 4080 Mobile will frequently be waiting on the CPU to feed it draw calls and physics calculations. The CPU's PassMark single-thread score of 3648 is respectable, but the multi-thread score of 12805 indicates that heavily threaded game logic or background tasks will consume available headroom quickly. The PassMark physics score of 685 is particularly telling, as physics simulations often scale poorly across few cores and can become a bottleneck in complex scenes.

For productivity applications that leverage GPU acceleration, the balance shifts. The RTX 4080 Mobile's 24.72 TFLOPS of FP32 performance and 432.0 GB/s of memory bandwidth can accelerate rendering, encoding, and compute tasks far beyond what the CPU could achieve on its own. In these scenarios, the CPU's role is primarily to feed data to the GPU, and the 8440U's 89.6 GB/s of memory bandwidth becomes a limiting factor for large dataset transfers.

# Benchmark Performance

The CPU's benchmark suite reveals a processor that excels in single-threaded tasks relative to its multi-threaded capacity. The Cinebench R15 single-core score of 154 and multi-core score of 1097 show a 7.1x scaling factor, which is lower than ideal for an 8-thread part, indicating some efficiency loss under full load. The Cinebench R20 scores follow a similar pattern: 645 single-core and 4571 multi-core, a ratio of 7.1x. The R23 scores of 1536 and 10884 maintain the same 7.1x ratio.

PassMark results provide additional granularity. The integer math score of 37468 and floating point math score of 23017 show a 1.6x advantage for integer operations, which is typical for consumer processors. The extended instructions score of 11059 and data encryption score of 8012 indicate solid SIMD and cryptographic throughput. Data compression scores 146273, while random string sorting reaches 17725. The find prime numbers score of 43 is modest, reflecting the CPU's limited multi-threaded integer throughput under this specific workload.

The GPU's benchmark profile is dominated by its DirectX and compute performance. The PassMark G3D score of 24926 places it in the upper tier of mobile graphics, while the G2D score of 929 reflects 2D desktop acceleration capabilities. DirectX 11 scores 244, DirectX 10 scores 157, and DirectX 12 scores 96, showing expected scaling across API generations. The DirectX 9 score of 286 is the highest of the DirectX tests, which is common for modern GPUs running legacy APIs. The GPU compute score of 11191 demonstrates substantial compute throughput, while Geekbench OpenCL scores 159575 and Vulkan scores 145807.

The combined percentile of 76 for this CPU+GPU pairing places it above the majority of laptop configurations. The CPU's 70th percentile and GPU's 81st percentile combine to create a system that is more capable in graphics-intensive workloads than in CPU-bound tasks. The average benchmark scores reinforce this: the CPU's 16663 vs. the GPU's 38135, a 2.3x difference that will manifest in real-world applications as GPU-heavy tasks performing disproportionately well relative to CPU-heavy tasks.

# CPU Analysis

The AMD Ryzen 3 8440U is built on the Zen 4 architecture, codenamed Hawk Point, and manufactured on TSMC's 4 nm process. The chip contains 20,900 million transistors on a 137 mm² die, reflecting a dense design that prioritizes power efficiency for mobile use. The 28 W TDP is modest, allowing for thin-and-light laptop implementations while still delivering competitive performance.

The processor features 4 cores and 8 threads, with a base clock of 3.00 GHz and a boost clock of 4.70 GHz. The cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and 8 MB of shared L3 cache. This configuration is adequate for single-threaded responsiveness but limits multi-threaded throughput compared to higher-core-count parts in the Ryzen 8000 series.

Memory support is limited to DDR5 in a dual-channel configuration, providing 89.6 GB/s of bandwidth. ECC memory is not supported, which positions this CPU for consumer and mainstream business use rather than mission-critical server workloads. The PCIe Gen 4 interface with 14 lanes from the CPU provides adequate connectivity for a discrete GPU and NVMe storage, though the lane count is lower than desktop parts.

The integrated Radeon 740M graphics provide a fallback display output when the discrete GPU is not in use, though the RTX 4080 Mobile will handle all demanding graphics workloads. The CPU is not multiplier-unlocked, so overclocking is not available on this platform. The production status is active, with a release date of December 5, 2023, and the part number is listed as 100-000001325 (FP7r2) or 100-000001332 (FP7).

Benchmark results show a processor that is competitive with its direct rivals but not class-leading. The Cinebench R23 multi-core score of 10884 places it within 1 percent of the Intel Core Ultra 5 115U, Intel Core i5-1235U, AMD Ryzen 3 7335U, and Intel Core i3-12100E. The single-core score of 1536 is similarly competitive. For real workloads, this means the 8440U will handle everyday productivity tasks such as web browsing, document editing, and spreadsheet work without perceptible lag, but will strain under heavy multi-threaded compilation, video encoding, or 3D rendering.

# Who Should Build It

This configuration targets users who prioritize GPU performance above all else and are willing to accept a mid-range CPU as the pairing partner. The 70th percentile CPU and 81st percentile GPU create a system that is well-suited for specific use cases where graphics acceleration dominates the workload profile.

Gamers who play at 1440p or 4K resolutions will find the RTX 4080 Mobile capable of driving high frame rates, and at these resolutions the CPU bottleneck becomes less pronounced. Content creators who rely heavily on GPU-accelerated rendering in applications like video editors or 3D modeling software will benefit from the GPU's compute capabilities. The 24.72 TFLOPS of FP32 performance and 12 GB of VRAM provide ample headroom for complex scenes and high-resolution textures.

Software developers working on GPU compute projects, such as machine learning inference or real-time graphics, will find the CUDA-capable RTX 4080 Mobile useful. The 232 tensor cores provide acceleration for AI workloads, while the 58 RT cores handle ray tracing calculations. The CPU's 8 threads are sufficient for compiling moderate-sized codebases, though large builds will take longer than with higher-core-count processors.

Students and small business users who need a laptop that can handle occasional gaming or GPU-accelerated applications will find this configuration adequate, though the CPU's 70th percentile places it below what some professional workloads require. The build class is laptop, indicating this is a mobile platform designed for portability rather than desktop replacement performance.

# Usage Scenarios

High-refresh gaming: The RTX 4080 Mobile's 81st percentile GPU performance, combined with 12 GB of VRAM and 432.0 GB/s of bandwidth, will drive high frame rates at 1080p and 1440p in most titles. The CPU's single-core score of 1536 in Cinebench R23 ensures that frame pacing remains consistent in games that are not heavily multi-threaded. At 4K, the GPU becomes the primary bottleneck, which is favorable for this pairing.

Streaming: The GPU's NVENC encoder, part of the Ada Lovelace architecture, handles video encoding without burdening the CPU. The CPU's 8 threads remain available for game logic and streaming software overhead. The PassMark multi-thread score of 12805 indicates that simultaneous gaming and encoding is feasible, though CPU-intensive games may cause frame drops.

Video editing: GPU-accelerated effects and timeline rendering will leverage the RTX 4080 Mobile's compute performance. The 24.72 TFLOPS FP32 throughput and 232 tensor cores provide substantial acceleration for effects that use AI-based tools. The CPU's 8 MB of L3 cache and 89.6 GB/s memory bandwidth are sufficient for 1080p and 1440p editing workflows, though 4K multi-stream projects may strain the processor.

3D rendering: GPU-based renderers such as those using CUDA will see excellent performance from the RTX 4080 Mobile. The 24.72 TFLOPS FP32 and 12 GB VRAM allow for reasonably complex scenes to fit in memory. CPU-based rendering will be slower, with the Cinebench R23 multi-core score of 10884 placing it in the mid-range for such tasks.

Software development: Compilation performance depends on the CPU's multi-threaded throughput. The PassMark integer math score of 37468 and multi-thread score of 12805 indicate moderate compilation speed for small-to-medium projects. The GPU's compute capabilities are useful for developers targeting CUDA or using GPU-accelerated libraries, with the 232 tensor cores supporting AI/ML development.

Student and office work: The CPU's single-core performance, as indicated by the Cinebench R23 single-core score of 1536, handles web browsing, document editing, and spreadsheet tasks smoothly. The GPU is overkill for these workloads, but the system will remain responsive under multitasking. The 28 W CPU TDP contributes to longer battery life, though the 110 W GPU TDP will draw significant power when active.

# Upgrade Path and Platform

The CPU uses AMD Socket FP7, which is a mobile-specific package. This limits upgradeability, as the processor is soldered to the motherboard in most laptop designs. Memory support is limited to DDR5 in dual-channel configuration, with 89.6 GB/s of bandwidth. The platform does not support ECC memory.

The GPU connects via PCIe 4.0 x16, which provides sufficient bandwidth for the RTX 4080 Mobile's 12 GB of GDDR6 memory. The GPU's TDP is 110 W, and the CPU's TDP is 28 W, for a combined thermal envelope of 138 W. The suggested PSU is null, meaning no specific power supply recommendation is provided, but the system will require a substantial battery and cooling solution given the GPU's power draw.

The PCIe Gen 4 interface with 14 lanes from the CPU supports NVMe SSDs at full speed and the discrete GPU. The integrated Radeon 740M provides a secondary display output, which can be used for power-saving modes or multi-monitor setups. The GPU's bus interface is PCIe 4.0 x16, which is fully compatible with the CPU's PCIe Gen 4 support.

A sensible next upgrade for this platform would be increasing system memory, as DDR5 is supported and the 89.6 GB/s bandwidth can be fully utilized with dual-channel configuration. Storage upgrades via NVMe are also straightforward, given the PCIe Gen 4 support. The GPU and CPU are both soldered, so neither can be upgraded without replacing the entire laptop.

# Gaming Performance

No measured FPS data exists for this exact CPU+GPU combination. The FACT PACK contains no measuredFps entries, so all frame rate figures discussed here are estimates derived from the benchmark scores rather than direct measurements. The dataIsMeasured field is false, indicating that this pairing has not been empirically tested in games.

Based on the GPU's PassMark G3D score of 24926 and its 81st percentile ranking, the RTX 4080 Mobile should deliver high frame rates in most modern titles at 1080p and 1440p with ultra settings. The 12 GB of VRAM is sufficient for high-resolution textures and ray tracing at these resolutions. The GPU's 432.0 GB/s memory bandwidth supports high texture throughput, while the 80 ROPs ensure efficient pixel processing.

The CPU's gaming performance is the limiting factor. The Cinebench R23 single-core score of 1536 indicates strong per-thread performance, which is critical for game logic. However, the 4-core, 8-thread configuration may cause frame drops in games that utilize more than 8 threads effectively. The PassMark physics score of 685 suggests that physics-heavy games may see reduced performance.

At 1080p, the CPU is more likely to bottleneck the GPU in esports titles or games with high CPU overhead. At 1440p and 4K, the GPU becomes the primary bottleneck, making the CPU's limitations less noticeable. For ray tracing workloads, the RTX 4080 Mobile's 58 RT cores and 232 tensor cores provide hardware acceleration, but the CPU must still handle the associated overhead.
