This build pairs AMD's Ryzen 5 8400F with NVIDIA's GeForce RTX 4080 SUPER, creating a desktop platform that targets high-refresh 1440p gaming and serious content creation. The benchmark data shows a system with a combined percentile of 82, placing it well above the majority of tested configurations. Measured FPS figures across a broad game library indicate that the RTX 4080 SUPER is the dominant component, while the 6-core CPU provides enough throughput to avoid major bottlenecks in most scenarios.

Gaming Performance — measured FPS by game and resolution from measuredFpsUltraByGame

The measured FPS data at ultra settings reveals a clear performance tiering across resolutions. At 1920x1080, the system delivers exceptional frame rates in esports titles, with Counter-Strike 2 achieving 323 FPS, Valorant hitting 463.8 FPS, and Tom Clancy's Rainbow Six Siege reaching 384 FPS. These numbers confirm that the pairing is overkill for 1080p competitive gaming, as the GPU is capable of far higher output than most 1080p displays can show.

Moving to 2560x1440, the data shows a more balanced picture. Counter-Strike 2 still delivers 214 FPS, while Valorant remains extremely high at 435.8 FPS. For AAA titles, the results are strong: Cyberpunk 2077 runs at 71 FPS, Red Dead Redemption 2 at 65 FPS, and Call of Duty: Warzone at 129.6 FPS. The 1440p resolution appears to be the sweet spot for this combination, with most demanding games maintaining frame rates well above 60 FPS.

At 3840x2160, performance drops significantly but remains playable for many titles. Cyberpunk 2077 falls to 47 FPS, Red Dead Redemption 2 to 43 FPS, and Ark: Survival Ascended to 16 FPS, which is the lowest figure in the dataset. However, lighter titles still perform well at 4K: Counter-Strike 2 manages 120 FPS, Roblox achieves 154.7 FPS, and Valorant stays at 406.1 FPS. The data suggests that 4K gaming is viable for esports and older titles, but demanding modern games will require upscaling technologies.

The average FPS across all tested games is 200.4, placing this pairing at rank 264 out of 3861 pairs. This indicates that, on average, this system outperforms the vast majority of CPU-GPU combinations in the benchmark database. Notably, the frame rate scaling from 1080p to 1440p shows an average reduction of approximately 35%, while the drop from 1440p to 4K averages around 45%, which is typical for a high-end GPU constrained by memory bandwidth at higher resolutions.

Balance and Bottleneck — which component limits which workload, using percentiles and FPS scaling as evidence

The benchmark data indicates that the RTX 4080 SUPER is the primary performance driver in this pairing. The GPU holds an 86th percentile ranking among all GPUs, while the Ryzen 5 8400F sits at the 77th percentile among CPUs. This 9-percentage-point gap suggests that the CPU is the weaker link in the chain, particularly in scenarios that heavily favor graphics throughput.

Evidence of CPU limitation appears in the FPS scaling data. In esports titles like Counter-Strike 2, the frame rate at 1080p is 323 FPS, but at 1440p it drops to 214 FPS. This reduction is larger than what pure GPU scaling would predict, indicating that at lower resolutions the CPU becomes a factor in maintaining maximum frame rates. Conversely, in GPU-bound titles like Cyberpunk 2077, the scaling from 1080p (94 FPS) to 1440p (71 FPS) follows a more predictable GPU-driven curve.

The CPU's single-thread performance, measured at 951 in 3dmark_single_thread and 3685 in PassMark single-thread tests, is sufficient for most gaming workloads. However, the 6-core, 12-thread configuration with a 16 MB L3 cache may struggle in heavily threaded scenarios. The multi-threaded scores, such as 20851 in Cinebench R23, are respectable but not exceptional, meaning games that utilize more than 6 cores effectively could see the CPU become a limiting factor.

The GPU's massive compute resources, including 10240 shading units and 52.22 TFLOPS FP32 performance, create a wide imbalance in raw compute capability versus the CPU. In GPU-intensive workloads like 4K rendering or ray tracing, the RTX 4080 SUPER will be the clear bottleneck. Conversely, in CPU-bound scenarios like high-frequency esports gaming at 1080p, the Ryzen 5 8400F may prevent the GPU from reaching its full potential.

Benchmark Performance — exact CPU and GPU scores, percentile positions, and what the combined picture is

The CPU's average benchmark score is 25005, placing it in the 77th percentile of all processors. Its nearest rival is the AMD Ryzen 5 7500F, which scores 24964, a delta of just 0.2%. This shows that the 8400F is essentially performance-equivalent to its sibling, with the difference being within measurement noise. The Intel Core i7-11850H at 24935 (0.3% delta) and Intel Core i7-13620H at 24911 (0.4% delta) are also close, while the AMD EPYC 9474F at 25103 is only 0.4% higher.

The GPU's average benchmark score is 54209, placing it in the 86th percentile of all graphics cards. Its closest rival is the NVIDIA GeForce RTX 4080, scoring 54247 with a delta of -0.1%, meaning the SUPER variant is essentially identical in average performance. The AMD Radeon Pro W5700X at 54828 is 1.1% higher, while the AMD Radeon RX 6750 GRE 12 GB at 55698 is 2.7% higher, and the AMD Radeon 8060S at 55757 is 2.8% higher. These deltas indicate that despite the SUPER's high percentile, several competitors outperform it in aggregate benchmarks.

Combined, the two components achieve an 82nd percentile ranking. This aggregate figure is lower than the GPU's individual percentile due to the CPU's relatively weaker position. In practical terms, the system delivers strong 1440p performance but may not fully utilize the GPU's capabilities in CPU-light workloads. The 3DMark results further clarify this: the GPU scores 6600 in Steel Nomad DX12, while the CPU's max-thread score is 6165, showing that both components are capable but the GPU has more headroom in graphics-specific tests.

Who Should Build It — target users and industries tied strictly to the measured performance

This build is best suited for gamers who prioritize high-refresh 1440p gameplay. The measured FPS data shows that at 2560x1440, the system achieves over 100 FPS in most tested titles, including demanding games like Call of Duty: Warzone (129.6 FPS) and Fortnite (96.8 FPS).
