# AMD Ryzen 3 5425U + NVIDIA GeForce RTX 4080 Mobile

This analysis covers a laptop pairing of AMD's Ryzen 3 5425U processor with NVIDIA's GeForce RTX 4080 Mobile GPU. The combination is unusual: a 15 W ultra-low-power quad-core CPU paired with a 110 W flagship-class mobile GPU. The benchmark data shows a combined percentile of 67 across all systems, with the CPU sitting at the 52nd percentile and the GPU at the 81st percentile. No measured FPS data exists for this exact combination, so all frame rate discussions are estimates derived from the individual component benchmark scores.

Usage Scenarios

High-refresh gaming: The RTX 4080 Mobile's PassMark G3D score of 24,926 and GeekBench Vulkan score of 145,807 place it in the 81st percentile of all GPUs, indicating strong potential for high-refresh 1080p and 1440p gaming. However, the Ryzen 3 5425U's single-core GeekBench score of 1,328 and Cinebench R23 single-core score of 1,332 may limit frame pacing in CPU-bound titles. The GPU is clearly capable of driving high frame rates, but the CPU's 52nd percentile standing suggests it could bottleneck in esports titles where frame rates exceed 200 FPS.

Streaming: The RTX 4080 Mobile's 232 tensor cores and 58 RT cores provide dedicated hardware for encoding and AI-enhanced streaming features. The GPU's GeekBench OpenCL score of 159,575 indicates substantial compute headroom for simultaneous gaming and encoding workloads. However, the Ryzen 3 5425U's 4 cores and 8 threads may struggle with the additional overhead of streaming software, as its multi-core Cinebench R23 score of 5,954.5 is modest by modern standards.

Video editing: The GPU's 12 GB GDDR6 memory with 432 GB/s bandwidth and 24.72 TFLOPS FP32 performance make it well-suited for GPU-accelerated effects, rendering, and color grading. The CPU's multi-core GeekBench score of 3,880 and Cinebench R23 multi-core score of 5,954.5 provide adequate but not exceptional performance for timeline scrubbing and preview generation. Export times will be primarily GPU-bound, which favors this pairing for editors using hardware-accelerated codecs.

3D rendering: The RTX 4080 Mobile's 7,424 shading units and 24.72 TFLOPS FP32 throughput place it comfortably ahead of most mobile GPUs, with its PassMark G3D score of 24,926 ranking in the 81st percentile. For GPU-based renderers like those using CUDA or OptiX, this GPU delivers strong performance. CPU-based rendering, however, will be limited by the Ryzen 3 5425U's 4 cores, with its Cinebench R23 multi-core score of 5,954.5 placing it near rivals like the Ryzen 5 6600HS (deltaPct 0.1) and Intel Core i3-13100TE (deltaPct 0.4).

Software development: The CPU's 4 cores and 8 threads, running at 2.70 GHz base and 4.10 GHz boost clocks, provide sufficient performance for compilation tasks of small to medium projects. Its single-core GeekBench score of 1,328 and Cinebench R23 single-core score of 1,332 indicate responsive IDE usage and quick single-threaded builds. Large parallel compilations will reveal the CPU's limitations, as its multi-core score of 3,880 in GeekBench trails many desktop-class alternatives.

Student and office work: The Ryzen 3 5425U's 15 W TDP makes it highly efficient for battery-conscious workloads. Its 52nd percentile ranking across all CPUs means it handles everyday productivity tasks competently, with the integrated Radeon Vega 6 providing a fallback when the discrete GPU is idle. The CPU's 8 MB shared L3 cache and DDR4 dual-channel memory support at 51.2 GB/s bandwidth ensure smooth multitasking for document editing, web browsing, and spreadsheet work.

Balance and Bottleneck

The performance asymmetry between the CPU and GPU is the defining characteristic of this pairing. The GPU's average benchmark score of 38,135 and 81st percentile placement dwarf the CPU's average benchmark score of 3,124 and 52nd percentile placement. In GPU-bound workloads like 3D rendering, video encoding, and modern AAA gaming at high resolutions, the RTX 4080 Mobile will be the primary performance driver, with the CPU providing adequate frame delivery.

In CPU-bound scenarios — esports titles at low settings, simulation games, or heavily threaded productivity apps — the Ryzen 3 5425U becomes the limiting factor. Its multi-core Cinebench R23 score of 5,954.5 is only 0.1% above the Ryzen 5 6600HS and 0.4% above the Intel Core i3-13100TE, placing it in a tightly competitive mid-range segment. The GPU's PassMark G3D score of 24,926 with an 81st percentile means it can output far more frames than the CPU can process in many gaming scenarios.

Memory bandwidth presents another potential bottleneck. The CPU's dual-channel DDR4 support provides 51.2 GB/s, while the GPU has its own 432.0 GB/s of dedicated GDDR6 bandwidth. In mixed workloads where data must transfer between CPU and GPU over PCIe Gen 3 (CPU) and PCIe 4.0 x16 (GPU), the CPU's older PCIe generation may limit data transfer rates, though the practical impact depends on workload characteristics.

Benchmark Performance

The CPU benchmarks show a balanced but modest processor. Cinebench R23 multi-core achieves 5,954.5 points, while single-core reaches 1,332 points. GeekBench results are 3,880 multi-core and 1,328 single-core. The average benchmark score of 3,124 places it at the 52nd percentile of all CPUs, with nearest rivals including the Ryzen 5 6600HS (deltaPct 0.1), Intel Core i3-13100TE (deltaPct 0.4), Ryzen 5 5625U (deltaPct 0.9), and Intel Xeon E5-2650 v4 (deltaPct -0.9).

The GPU benchmarks demonstrate significantly stronger relative performance. PassMark G3D scores 24,926, with DirectX 12 at 96, DirectX 11 at 244, DirectX 10 at 157, and DirectX 9 at 286. Compute performance via PassMark GPU Compute reaches 11,191, while GeekBench OpenCL scores 159,575 and Vulkan scores 145,807. The 2D performance of 929 in PassMark G2D is modest. The average benchmark score of 38,135 places the GPU at the 81st percentile, with nearest rivals including the RTX 5080 Mobile (deltaPct -0.6), MX570 (deltaPct -0.4), RTX 4070 (deltaPct 1.3), and Tesla P4 (deltaPct 1.3).

The combined picture is a system where the GPU delivers top-quartile performance while the CPU delivers mid-range performance. The combined percentile of 67 reflects this disparity, indicating that the overall system ranks above average but below what the GPU alone would suggest.
