# AMD Ryzen 7 8840U + NVIDIA GeForce RTX 4080 Mobile

This laptop pairing combines AMD's efficient Zen 4 mobile processor with NVIDIA's high-end Ada Lovelace discrete GPU, creating a system that sits at the 79th combined percentile across all benchmarked configurations. The CPU is a 28 W part built for thin-and-light machines, while the GPU is a 110 W mobile flagship, making this an unusual but potentially potent combination for users who need both portability and graphics horsepower in a single chassis.

CPU Analysis

The AMD Ryzen 7 8840U is an 8-core, 16-thread processor based on the Zen 4 architecture, codenamed Hawk Point, and manufactured on TSMC's 4 nm process. It belongs to AMD's 8000 series and features a base clock of 3.30 GHz with a boost clock of 5.10 GHz, a substantial frequency range that allows the chip to scale from power-efficient idle states to demanding single-threaded workloads. The processor integrates 25,000 million transistors on a 178 mm² die, with a cache hierarchy comprising 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache.

Benchmark results reveal a processor that is notably strong in multi-threaded tasks relative to its modest 28 W TDP. In Cinebench R23, the 8840U scores 12,972 points in multi-core and 1,703 points in single-core, while Geekbench shows 9,610 multi-core and 1,970 single-core. The 3DMark thread scaling tests are particularly informative: the CPU scores 5,691 with 16 threads and 5,677 at max threads, but drops to 4,896 with 8 threads, 3,289 with 4 threads, and 1,863 with 2 threads. This scaling pattern indicates that the processor's performance is heavily dependent on thread count, with diminishing returns beyond 8 threads due to the 28 W power envelope limiting sustained all-core boost clocks.

PassMark results reinforce this picture. The multithread score of 23,346 is respectable for a mobile processor, and integer math (85,740) significantly outperforms floating-point math (48,820), suggesting the chip is well-suited for general productivity and data manipulation tasks. Data compression scores are exceptionally high at 267,525, while encryption (16,072) and extended instructions (18,654) show moderate performance. The single-thread score of 3,543 is competitive, and the processor's 76th percentile ranking among all CPUs places it above most mainstream desktop processors from a few generations ago, despite being designed for mobile power efficiency.

The 8840U's nearest rivals in average benchmark score include the AMD Ryzen 5 8600G (0.4% ahead), the AMD Ryzen 5 7540U (0.9% ahead), the Intel Xeon 6333P (0.7% behind), and the Intel Core i5-11500 (1.1% behind). This clustering around the 24,000 average benchmark score mark indicates that the 8840U delivers performance comparable to mid-range desktop processors, which is remarkable for a 28 W mobile chip. The inclusion of the Radeon 780M integrated graphics adds flexibility, allowing the system to function even without the discrete GPU active.

Benchmark Performance

The combined benchmark picture for this CPU+GPU pairing places it at the 79th percentile among all tested configurations, reflecting a system that is firmly in the upper tier of laptop performance. The CPU's average benchmark score of 23,982 and the GPU's average of 38,135 contribute to a balanced overall profile, though the GPU clearly carries more weight in graphics-intensive workloads.

The RTX 4080 Mobile achieves a PassMark G3D score of 24,926, which places it in the 81st percentile among all GPUs. Its nearest rivals are intriguing: the NVIDIA GeForce MX570 (0.4% behind), the NVIDIA GeForce RTX 5080 Mobile (0.6% behind), the NVIDIA GeForce RTX 4070 (1.3% ahead), and the NVIDIA Tesla P4 (1.3% ahead). The fact that the newer RTX 5080 Mobile scores nearly identically suggests that mobile GPU performance has hit a plateau at this tier, with architectural improvements offset by power and thermal constraints. The RTX 4070 desktop card being only 1.3% ahead is notable, indicating that the 4080 Mobile delivers desktop-class performance in a laptop form factor.

Geekbench scores for the GPU show strong compute capabilities: 159,575 in OpenCL and 145,807 in Vulkan. The PassMark GPU Compute score of 11,191 is more modest, suggesting that the GPU's compute performance varies significantly depending on the workload and API. DirectX 11 performance (244 in PassMark) is far stronger than DirectX 12 (96), which is counterintuitive for a modern GPU and suggests driver optimizations or benchmark methodology differences rather than raw capability limitations.

The CPU's percentile ranking at 76th among all CPUs means that roughly a quarter of processors outperform it, but given its power efficiency, this is an acceptable trade-off. The combined 79th percentile for the pairing indicates that the GPU boosts the overall system performance above what the CPU alone would suggest, making this configuration particularly well-suited for graphics-heavy applications where the CPU is not the primary bottleneck.

Upgrade Path and Platform

The AMD Ryzen 7 8840U uses the AMD Socket FP8, which is a mobile-specific socket designed for thin-and-light laptops. This means the CPU is soldered to the motherboard, and upgrades require replacing the entire system rather than swapping the processor. The platform supports dual-channel DDR5 memory with a bandwidth of 89.6 GB/s, and ECC memory is not supported. The CPU provides PCIe Gen 4 with 20 lanes, which is sufficient for a discrete GPU and NVMe storage, though the exact allocation depends on the laptop manufacturer's implementation.

The RTX 4080 Mobile connects via PCIe 4.0 x16 and has a TDP of 110 W, which is substantial for a laptop GPU but manageable in a larger chassis with adequate cooling. The GPU has no power connectors listed, indicating it draws power through the motherboard rather than requiring external PCIe power cables — this is typical for mobile GPUs where the entire power delivery system is integrated into the laptop's design. The suggested PSU field is null, which is expected for a mobile component where the power supply is internal and not user-replaceable.

For users considering an upgrade path, the reality is that this is a closed platform. The CPU and GPU are both soldered, and the laptop's cooling system, power delivery, and chassis are all designed around these specific components. A sensible "next upgrade" in practical terms would be moving to a newer laptop generation with the RTX 50-series mobile GPUs, given that the RTX 5080 Mobile scores nearly identically to the 4080 Mobile (only 0.6% difference), suggesting that generational gains in mobile graphics are currently modest. Alternatively, users could consider a desktop build for more flexibility, but that would be a different class of system entirely.

The memory bandwidth of 89.6 GB/s is shared between the CPU and the integrated Radeon 780M graphics when the discrete GPU is not in use, but when the RTX 4080 Mobile is active, it uses its own dedicated 12 GB of GDDR6 memory with 432.0 GB/s bandwidth. The CPU's PCIe Gen 4 support is adequate for the GPU's x16 interface and modern NVMe drives, though Gen 5 would offer more headroom for future storage devices.

The 12 GB VRAM is sufficient for 4K timelines with moderate effects, though very complex projects may exceed this capacity.

3D rendering: The GPU's compute scores (159,575 OpenCL, 145,807 Vulkan) indicate strong rendering performance in GPU-accelerated engines, and the 58 RT cores provide hardware ray tracing support. The CPU's Cinebench R23 multi-core score of 12,972 is adequate for CPU-based rendering but will be slower than desktop workstations, making this system better suited for hybrid rendering workflows.

Software development: The CPU's PassMark integer math score of 85,740 and data compression score of 267,525 indicate strong performance for compilation and data processing tasks. The 16 threads handle parallel builds effectively, and the 16 MB L3 cache reduces memory latency for frequently accessed code. The 89.6 GB/s memory bandwidth supports large in-memory datasets.

Student and office work: The 28 W TDP means excellent battery life for all-day productivity, and the CPU's single-thread performance (3,543 PassMark single-thread) handles office applications, web browsing, and document editing effortlessly. The integrated Radeon 780M can handle light graphics tasks without activating the discrete GPU, further extending battery life.

Gaming Performance

No measured FPS data exists for this exact CPU+GPU combination, so all frame rate figures discussed here are estimates derived from the benchmark scores rather than empirical measurements. The data is marked as not measured, meaning the following expectations should be treated as analytical projections based on the GPU's PassMark G3D score of 24,926 and 81st percentile ranking, combined with the CPU's 76th percentile ranking.

Based on the GPU's performance tier, this system should deliver high frame rates at 1080p ultra settings in most modern titles, with the 12 GB VRAM providing sufficient capacity for high-resolution textures. At 1440p, the 432.0 GB/s memory bandwidth and 24.72 TFLOPS FP32 performance should maintain playable frame rates in the 60-100 FPS range for most games, though demanding titles with heavy ray tracing may dip lower. The 58 RT cores provide hardware acceleration for ray-traced effects, and the 232 tensor cores enable DLSS upscaling, which can significantly boost frame rates at higher resolutions.

At 4K, the GPU is likely to struggle with ultra settings in the most demanding titles, but with DLSS enabled, playable frame rates are plausible in many games. The CPU's boost clock of 5.10 GHz and single-thread performance should not bottleneck the GPU in most scenarios, though the 28 W TDP may cause performance drops in CPU-intensive games with large numbers of NPCs or complex physics simulations. For competitive esports titles, this system should easily exceed 144 FPS at 1080p, and likely approach 240 FPS in less demanding games.

Build Overview

This is a laptop-class build, as indicated by the build class designation, combining the AMD Ryzen 7 8840U mobile processor with the NVIDIA GeForce RTX 4080 Mobile discrete GPU. The CPU is an 8-core, 16-thread Zen 4 processor with a 28 W TDP, designed for power-efficient mobile computing, while the GPU is a high-end mobile graphics solution with a 110 W TDP, 12 GB of GDDR6 memory, and Ada Lovelace architecture.

The combined percentile ranking of 79 places this system in the upper tier of laptop performance, with the GPU's 81st percentile ranking being the primary driver of overall performance. The CPU's 76th percentile ranking is respectable for a mobile processor but is the limiting factor in CPU-bound workloads. This pairing is somewhat imbalanced in that the GPU is significantly more powerful relative to its peers than the CPU, but this can be advantageous for graphics-intensive applications where the GPU is the primary bottleneck. The system's overall tier is that of a premium gaming or content-creation laptop, capable of handling demanding workloads while remaining portable enough for daily carry.

Balance and Bottleneck

The performance balance between these two components reveals a system where the GPU is the dominant performer relative to its peers. The RTX 4080 Mobile's 81st percentile ranking and average benchmark score of 38,135 significantly exceed the CPU's 76th percentile and 23,982 average score. In GPU-bound workloads like gaming at high resolutions, this imbalance is beneficial, as the CPU can keep up with the GPU's demands without becoming a bottleneck. The CPU's boost clock of 5.10 GHz and single-thread performance of 979 in 3DMark ensure that frame rates are not CPU-limited in most games.

However, in CPU-bound workloads such as physics simulations, AI inference, or heavily threaded productivity tasks, the CPU's 28 W power envelope will limit performance. The 3DMark thread scaling shows that performance increases significantly from 4 threads (3,289) to 8 threads (4,896) but only marginally from 8 to 16 threads (5,691), indicating that the CPU's power budget is exhausted beyond 8 cores. This means that applications that can effectively use more than 8 threads will see diminishing returns, and the GPU may be underutilized in these scenarios.

The GPU's nearest rivals include the RTX 5080 Mobile at nearly identical performance (0.6% behind), suggesting that this mobile GPU tier has reached a performance plateau. The CPU's nearest rival, the Ryzen 5 8600G, is only 0.4% ahead despite being a desktop processor, confirming that the 8840U extracts nearly all available performance from its 28 W budget. In practical terms, users will experience a system that excels at graphics-heavy tasks like gaming, video editing, and 3D rendering, but will see the CPU become the limiting factor in heavily threaded CPU workloads.
