On the other side, the AMD EPYC 9474F leads by a slim margin with a score of 25,103, a 0.4% advantage. This places the 8400F in a tight cluster where performance differences are negligible.

The GPU’s average benchmark score is 60,347, which puts it at the 88th percentile of all GPUs. Its nearest rivals show a wider spread: the Intel Arc Pro A60 scores 60,326 (0% delta), the AMD Radeon Pro Vega 48 scores 60,140 (0.3% slower), and the AMD Radeon PRO V710 scores 58,657 (2.9% slower). Interestingly, the AMD Radeon Pro W6600M is 2.5% faster with a score of 61,896. The 4090’s percentile ranking is high, but the deltaPct values reveal that a few workstation-class GPUs are within striking distance in synthetic benchmarks.

In multi-threaded CPU tests, the 8400F scores 6,165 in 3dmark_max_threads and 20,851 in Cinebench R23 multicore. Single-thread performance is also respectable, with 951 in 3dmark_single_thread and 2,943 in Cinebench R23 singlecore. The combined picture is a system where the GPU outranks the CPU by 11 percentile points (88 vs 77). The overall build percentile is 83, which is closer to the CPU’s standing than the GPU’s, suggesting that the processor is the limiting factor in many scenarios.

Gaming Performance

Measured FPS data is available across a wide range of titles at three resolutions. At 1920x1080, the system delivers high frame rates in most games: 359 FPS in Counter-Strike 2, 427 FPS in Tom Clancy's Rainbow Six Siege, and 461.2 FPS in Valorant. Heavier titles still perform well, with Cyberpunk 2077 hitting 96.7 FPS and Red Dead Redemption 2 reaching 100.1 FPS. The most demanding game in the dataset, Ark: Survival Ascended, manages 50.5 FPS at 1080p.

At 2560x1440, frame rates scale down predictably. Counter-Strike 2 drops to 238 FPS, Valorant stays high at 436.8 FPS, and Cyberpunk 2077 falls to 81.1 FPS. Ark: Survival Ascended becomes borderline playable at 31 FPS. The 1440p results show that the GPU is still strong enough for competitive titles, but the CPU begins to show its limits in the most CPU-intensive games.

At 3840x2160, the resolution becomes the bottleneck. Counter-Strike 2 runs at 133 FPS, Valorant at 408 FPS, and Cyberpunk 2077 at 49.6 FPS. Ark: Survival Ascended drops to 14.5 FPS, which is unplayable. The average FPS across all games is 213.7, and the pair ranks 137th out of 3,732 pairs by FPS, placing it in the top 3.7% of all recorded pairs. The data shows that 1080p and 1440p are the sweet spots, with 4K being viable only for less demanding titles.

Upgrade Path and Platform

The CPU uses AMD Socket AM5, which is the current desktop platform. Memory support is DDR5 with a dual-channel bus and 83.2 GB/s of bandwidth. The CPU provides PCIe Gen 4 with 20 lanes, while the GPU uses a PCIe 4.0 x16 interface. This is a modern platform that supports current DDR5 memory standards.

The GPU has a TDP of 450 W and the suggested PSU is 850 W. The CPU’s TDP is 65 W, so the power supply headroom is more than sufficient for the processor. The GPU is listed as end-of-life with a successor in the GeForce 50 series, so a future upgrade would involve replacing the graphics card. The CPU is still active in production, meaning it remains a current product.

A sensible next upgrade would be to replace the GPU with a newer model when the need arises, as the platform itself (AM5, DDR5, PCIe 4.0) is not the limiting factor. The CPU’s 65 W TDP leaves ample thermal and power headroom for a more power-hungry processor in the same socket, should the user want to move to a higher-core-count Ryzen later. However, the data suggests the current CPU is well-matched to the platform’s capabilities.

Balance and Bottleneck

The percentile gap between the CPU (77th) and GPU (88th) is 11 points, indicating an imbalance. In CPU-bound scenarios, such as esports titles at 1080p, the 8400F is the limiting factor. For example, Valorant at 1080p hits 461.2 FPS, but the GPU’s massive compute resources are not fully utilized at that resolution. The CPU’s single-thread score of 951 in 3dmark and 3,685 in Passmark single-thread determines the ceiling in these games.

In GPU-bound scenarios, such as 4K gaming or rendering workloads, the RTX 4090 is the constraining component. The FPS scaling from 1080p to 4K shows this clearly: Cyberpunk 2077 drops from 96.7 FPS to 49.6 FPS, a 51% reduction that is typical of GPU-limited performance. The CPU’s multi-thread score of 6,165 in 3dmark_max_threads is more than enough to feed the GPU at higher resolutions.

The pair’s rank of 137 out of 3,732 pairs by FPS confirms that, on average, the GPU is doing most of the heavy lifting. The bottleneck analysis shows that for maximum frame rates in competitive shooters, the CPU will hold back the GPU. For visually demanding single-player games and creative workloads, the GPU is the dominant factor, and the CPU is rarely the limiting component.

Build Overview

This is a desktop-class build combining a mid-range 6-core CPU with a flagship 24 GB GPU. The CPU is a Zen 4 (Phoenix) part on the AM5 platform, while the GPU is an Ada Lovelace-based RTX 4090. The combined percentile is 83, which reflects the GPU’s high standing (88th percentile) being dragged down slightly by the CPU’s more modest 77th percentile.

The overall tier is high-end for gaming, particularly at 1080p and 1440p, where the average FPS across games is 213.7. The pair ranks 137th out of 3,732 pairs, putting it in the top 4% of all recorded pairings. However, this is not a balanced workstation build. The CPU is the weak link for multi-threaded productivity, while the GPU is one of the most powerful consumer cards ever made. The build is best characterized as a gaming-first system with the GPU as the centerpiece.

Who Should Build It

Gamers targeting 1080p or 1440p with high refresh rates will find this build ideal. The measured FPS shows 359 FPS in Counter-Strike 2 and 427 FPS in Rainbow Six Siege at 1080p, which exceeds the refresh rate of most monitors. At 1440p, competitive titles still exceed 200 FPS, and demanding games like Cyberpunk 2077 run above 80 FPS. 4K gaming is possible but limited to less demanding titles, as evidenced by the 49.6 FPS in Cyberpunk 2077 at 3840x2160.

Content creators who work primarily with GPU-accelerated applications will benefit from the 24 GB VRAM and 82.58 TFLOPS of FP32 performance. The 128 RT cores and 512 tensor cores make this a capable machine for 3D rendering and AI workloads, though the CPU will bottleneck heavily threaded CPU-side tasks like video encoding or physics simulations.

Developers working on game engines or GPU compute will appreciate the Vulkan score of 271,631 and OpenCL score of 255,416. The 24 GB memory capacity allows for large dataset manipulation without swapping. Students and small business users who need a fast GPU for visualization but do not require high CPU core counts will find this build sufficient, provided their workloads are GPU-centric. For users who need balanced CPU and GPU performance for tasks like software compilation or heavy multitasking, this pairing is less suitable due to the CPU’s 6-core limitation.
