Overpower

The AMD Ryzen 5 7400F paired with the NVIDIA GeForce RTX 5090 D is an unusual combination: a mainstream six-core CPU harnessed to a flagship-class GPU. In Overpower, this pairing produces very high frame rates, but the data reveals a clear division of labor where the GPU dominates at higher resolutions and the CPU becomes a more noticeable factor at 1080p.

Resolution Scaling

The measured FPS data shows a predictable pattern: as resolution increases, average frame rates decrease. At Low settings, the average FPS drops from 243 at 1920x1080 to 234 at 2560x1440, and then to 222 at 3840x2160. That is a modest 8.6% reduction from 1080p to 4K at Low settings, which indicates that at lower graphical presets, the system is not purely GPU-limited even at 4K. The drop from 1440p to 4K at Low settings is only 5.1%, suggesting the CPU is holding performance relatively flat until the GPU workload becomes heavy enough.

At High settings, the scaling is more pronounced. The average FPS goes from 189 at 1080p to 169 at 1440p, then down to 144 at 4K. This represents a 23.8% decrease from 1080p to 4K, showing that as settings increase, the GPU becomes the primary limiter. The Medium settings data follows a similar trajectory: 203 FPS at 1080p, 182 at 1440p, and 155 at 4K. The gap between 1080p and 1440p at Medium is 10.3%, while the gap between 1440p and 4K is 14.8%, indicating a slightly steeper decline at the highest resolution.

Ultra settings show the largest absolute drop but the smallest relative difference between resolutions in this dataset. The average FPS is 157 at 1080p, 140 at 1440p, and 119 at 4K. The 1080p to 4K reduction is 24.2%, which is similar to High settings. However, the step from 1440p to 4K at Ultra is 15.0%, the largest single-step decline across all settings tiers. This suggests that at Ultra, the 4K resolution is pushing the RTX 5090 D hard enough that even its substantial compute resources are fully engaged.

The key takeaway from resolution scaling is that this combo is exceptionally strong at all tested resolutions. Even at 4K Ultra, the average FPS of 119 is well above the 60 FPS threshold, and at 1080p Low, the system reaches 243 FPS. The data shows that the limiting component shifts with resolution: at 1080p Low, the CPU likely constrains the GPU, but by 4K Ultra, the GPU is almost certainly the bottleneck, as CPU demands do not scale with resolution while GPU load does.

GPU Role

The NVIDIA GeForce RTX 5090 D is built on the Blackwell 2.0 architecture with a 5 nm process node and a massive 92,200 million transistors on a 750 mm² die. It features 32 GB of GDDR7 memory on a 512-bit bus, providing 1.79 TB/s of memory bandwidth. The GPU clocks run at 2017 MHz base and 2407 MHz boost, with memory at 1750 MHz (28 Gbps effective). These specifications translate into 21,760 shading units, 680 TMUs, and 176 ROPs, along with 170 RT cores and 680 tensor cores.

In the benchmark database, this GPU achieves a percentile rank of 92 among all GPUs, with an average benchmark score of 77,712. Its nearest rivals in the aggregate benchmark results include the AMD Radeon RX 6650M XT with an average score of 76,904 (1.1% ahead), the AMD Radeon RX 6850M XT at 78,940 (1.6% behind), and NVIDIA Tesla P100 variants at 79,396 and 79,605 (2.1% and 2.4% behind, respectively). The RTX 5090 D sits between these mobile and datacenter parts in the aggregate rankings, though its gaming performance in Overpower is clearly substantial.

The GPU's role in Overpower is most evident in the measured FPS data. At 4K Ultra, the average FPS of 119 demonstrates that the GPU is handling a heavy load, but it is not overwhelmed. The fact that the RTX 5090 D can push 119 FPS at 4K Ultra in a 2023 action game is a strong indicator of its capability. The 32 GB VRAM allocation is far beyond what Overpower likely requires at these settings, but the memory bandwidth of 1.79 TB/s ensures that texture streaming and high-resolution assets do not create stutters.

The GPU's compute performance, as measured by benchmarks like 3DMark Steel Nomad DX12 at 14,326 and Geekbench Vulkan at 376,915, supports the high frame rates observed. The FP32 throughput of 104.8 TFLOPS and pixel rate of 423.6 GPixel/s give the RTX 5090 D enough raw power to handle the demanding visual effects in Overpower at high resolutions. However, the data also shows that at lower settings and resolutions, the GPU is not fully utilized, as evidenced by the relatively small FPS gains from 1440p to 1080p at Low settings.

CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor from the 7000 series, based on the Zen 4 architecture (Raphael) on a 5 nm process. It has a base clock of 3.70 GHz and a boost clock of 4.70 GHz, with a TDP of 65 W. The CPU features 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 32 MB of shared L3 cache. It supports DDR5 memory in a dual-channel configuration with a memory bandwidth of 83.2 GB/s, and it has 24 PCIe Gen 5 lanes.

In aggregate benchmarks, the Ryzen 5 7400F achieves a percentile rank of 83 among all CPUs, with an average benchmark score of 32,750. Its nearest rivals are the Intel Core i5-14600T with an average score of 32,707 (0.1% ahead), the Intel Core Ultra 7 155H at 32,697 (0.2% ahead), the AMD Ryzen 7 PRO 6850H at 32,812 (0.2% behind), and the AMD Ryzen AI 7 PRO 360 at 32,662 (0.3% ahead). These differences are negligible, placing the 7400F in a tightly competitive band of mid-range processors.

In Overpower, the CPU's role is most visible at lower resolutions and settings. At 1080p Low, the average FPS of 243 is likely close to the CPU's maximum frame delivery capability for this game. The jump from 1080p Low to 1080p Medium is only 16.5% (from 243 to 203 FPS), which is a smaller relative increase than at higher resolutions, suggesting the CPU is starting to limit the GPU's ability to render more frames. At 1440p Low, the average FPS is 234, which is only 3.7% lower than 1080p Low, indicating that the CPU is still a significant factor at this resolution. Even at 4K Low, the 222 FPS average is within 8.6% of the 1080p Low figure.

The CPU's single-thread performance, as measured by Cinebench R23 single-core at 3,072 and PassMark single-thread at 3,689, is strong for a six-core part. The multi-threaded performance, with Cinebench R23 multi-core at 21,765 and PassMark multithread at 25,645, shows that the 7400F can handle the game's background tasks and physics without becoming a bottleneck in most scenarios. However, the data in Overpower suggests that at 1080p Low, the CPU is the limiting component, as the GPU would likely be capable of delivering even higher frame rates if the CPU could feed it more data.

Measured FPS Breakdown

At 1920x1080, the combo delivers an average of 243 FPS at Low settings, 203 FPS at Medium settings, 189 FPS at High settings, and 157 FPS at Ultra settings. The Medium settings run shows a minimum of 172 FPS and a maximum of 233 FPS, indicating a 61 FPS variance. The step from Low to Medium is a 16.5% reduction, while the step from Medium to High is 6.9%, and from High to Ultra is 16.9%. This non-linear scaling suggests that certain settings within the Medium preset are more demanding than those in High.

At 2560x1440, the average FPS values are 234 at Low, 182 at Medium, 169 at High, and 140 at Ultra. The Medium settings run shows a minimum of 155 FPS and a maximum of 209 FPS. The percentage drops from 1080p to 1440p are 3.7% at Low, 10.3% at Medium, 10.6% at High, and 10.8% at Ultra. These are relatively consistent reductions, indicating that the GPU is scaling predictably with pixel count at this resolution.

At 3840x2160, the average FPS values are 222 at Low, 155 at Medium, 144 at High, and 119 at Ultra. The Medium settings run shows a minimum of 132 FPS and a maximum of 178 FPS. The drops from 1440p to 4K are 5.1% at Low, 14.8% at Medium, 14.8% at High, and 15.0% at Ultra. The larger drops at higher settings confirm that the GPU is increasingly the bottleneck at 4K, especially when graphical fidelity is prioritized.

The data shows that the system is capable of running Overpower at 4K Ultra with an average of 119 FPS, which is a strong result. At 1080p Low, the 243 FPS average suggests that the system could potentially exceed 240 Hz refresh rates, but the CPU may prevent higher frame rates. Across all resolutions and settings, the combo maintains an average FPS above 119, with the lowest recorded minimum FPS being 132 at 4K Medium, indicating smooth performance without major frame drops.

How This Combo Ranks

The combo rank for this specific pairing in Overpower is 53 out of 2,980 tested combinations. This places it in the top 1.8% of all tested combos, which is an exceptionally strong result. The rank of 53 means that only 52 other combinations of CPUs and GPUs produced higher average FPS in this game across the tested configurations.

Given that the RTX 5090 D is a flagship-class GPU and the Ryzen 5 7400F is a mid-range CPU, this rank suggests that the GPU is doing the heavy lifting in Overpower. The fact that this combo ranks 53rd overall, despite the CPU being only in the 83rd percentile among all CPUs, indicates that the game is heavily GPU-bound at the settings tested. The RTX 5090 D's 92nd percentile ranking among GPUs aligns well with the combo's top-tier performance.

The rank also implies that there are 52 combos that outperform this pairing, likely featuring more powerful CPUs such as higher-core-count Ryzen 9 or Core i9 parts paired with the same or similar GPUs. However, the performance difference between this combo and those ranked above it is likely small, given that the average FPS values are already very high. At 4K Ultra, the 119 FPS average is within a reasonable range of what more expensive CPU pairings might achieve, as the GPU becomes the primary limiter at that resolution.

In the context of the CPU's nearest rivals, the Ryzen 5 7400F's aggregate score is nearly identical to the Intel Core i5-14600T, Intel Core Ultra 7 155H, AMD Ryzen 7 PRO 6850H, and AMD Ryzen AI 7 PRO 360. This means that swapping the 7400F for any of these CPUs would likely result in a negligible change in Overpower performance, especially at higher resolutions where the GPU dominates. The combo's rank of 53 is therefore a signal of the GPU's capability rather than the CPU's.
