Overpower

The Intel Core i5-10400F paired with the AMD Radeon RX 7900 XTX in Overpower presents a study in asymmetry: a six-core, 12-thread Comet Lake processor from 2020 driving a flagship RDNA 3.0 GPU. The CPU's base clock of 2.90 GHz and boost clock of 4.30 GHz, combined with a 12 MB shared L3 cache, are respectable for the platform's era, but the data indicates this processor is the limiting factor in several key scenarios. In synthetic multi-threaded workloads, the i5-10400F scores 4,748 in the 3DMark 16-thread test and 10,297 in Cinebench R23 multi-core, placing it in the 73rd percentile of all CPUs. Its nearest rivals, such as the AMD EPYC 7552 and the Intel Core i5-8500, show average scores within 1.1% of this chip, confirming that the i5-10400F is positioned firmly in the mid-range of desktop performance. The single-thread performance, however, is more modest, with a 3DMark single-thread score of 688 and a Geekbench single-core score of 1,454, which directly impacts the frame pacing in a real-time action title like Overpower.

The 14 nm process node and 65 W TDP are architectural constraints that define the CPU's capabilities. While the CPU has six physical cores, which is adequate for modern gaming, the raw per-core throughput is not exceptional by current standards. This becomes obvious when examining the measured frame rates: the CPU's ceiling appears to be around 165.9 FPS at 1080p Low settings, a figure that does not change dramatically when the resolution is lowered further. The 12 threads help with background tasks and game logic, but the processor's 42.7 GB/s memory bandwidth and PCIe Gen 3 interface are potential bottlenecks for a GPU with a 960.0 GB/s memory bus. In essence, the CPU provides a stable, but not overwhelming, foundation; its role is to feed the GPU, and the data suggests it does so adequately at lower resolutions but begins to constrain the GPU's potential at higher settings.

FAQ

Q: How does the i5-10400F compare to its closest CPU rivals in overall benchmark scores?

A: The i5-10400F has an average benchmark score of 14,168. Its nearest rival, the AMD EPYC 7552, scores 14,115, which is 0.4% slower. Conversely, the AMD Ryzen 3 7320C scores 14,277 (0.8% faster), and the Intel Core i5-8500 scores 14,332 (1.1% faster). The performance deltas are minimal, indicating the i5-10400F is statistically on par with these chips.

*Q: What is the maximum average frame rate achievable with this combo in Overpower?*

A: The highest average FPS recorded is 165.9 at 1920x1080 with Low settings. This is only marginally higher than the 164.2 FPS seen at 2560x1440 Low, suggesting that the CPU, rather than the GPU, is capping performance at this extreme low-setting configuration.

Q: Does the RX 7900 XTX's 24 GB of VRAM provide a benefit in this game?

A: The data shows consistent frame rates across all settings at a given resolution, which implies that VRAM capacity is not a limiting factor. At 4K Ultra, the combo still manages 91.3 FPS, indicating the 24 GB of GDDR6 memory is sufficient for Overpower's demands, and the bottleneck lies elsewhere, likely in the CPU or the GPU's shading throughput.

Q: How does the combo's frame rate scale when moving from 1080p to 1440p?

A: At High settings, the average FPS drops from 138.6 at 1080p to 128.1 at 1440p, a reduction of 10.5 FPS. This relatively small delta suggests that the GPU has ample headroom, and the CPU is starting to become a more significant factor in the 1440p results.

Q: What is the combo's rank among all tested configurations in this game?

A: The combo ranks 380th out of 1,744 tested combos. This places it in the top 21.8% of all configurations, which is a strong result, but it also shows that many other CPU-GPU pairings are capable of higher performance in Overpower.

Q: Is the RX 7900 XTX's performance close to its nearest GPU rivals?

A: The RX 7900 XTX has an average benchmark score of 44,019. Its nearest rival, the AMD Radeon Pro 580, scores 44,195, which is only 0.4% faster. The NVIDIA GeForce RTX 4090 Mobile scores 43,667 (0.8% slower), and the NVIDIA Quadro M6000 scores 43,313 (1.6% slower). The differences are small, meaning the RX 7900 XTX is firmly in the same performance tier as these other high-end cards.

Resolution Scaling

The resolution scaling data for this combo in Overpower reveals a classic pattern of a GPU-bound system at higher resolutions, with the CPU becoming more prominent as resolution drops. At 4K Ultra, the average FPS is 91.3. Moving down to 2560x1440 Ultra increases the average to 107.5 FPS, a gain of 16.2 FPS. At 1920x1080 Ultra, the average rises further to 121 FPS. This progression shows that the GPU is the primary driver of performance at 4K, where its 61.39 TFLOPS of FP32 compute is heavily utilized. The RX 7900 XTX's 192 ROPs and 479.6 GPixel/s pixel rate are clearly enough to handle the pixel fill demands of 4K, but the frame rates are still respectable, suggesting the game is not overly demanding at this resolution.

The picture changes dramatically when moving to Low settings. At 4K Low, the average FPS is 154, which is a massive jump from the Ultra preset. However, the scaling between resolutions at Low settings is almost flat: 165.9 FPS at 1080p, 164.2 FPS at 1440p, and 154 FPS at 4K. The difference between 1080p and 4K at Low is only 11.9 FPS. This plateau is the clearest indicator of a CPU bottleneck. The i5-10400F's single-thread score of 688 in 3DMark and its Passmark single-thread score of 2,541 are the limiting factors here. The GPU is so powerful that it can render the low-detail frames far faster than the CPU can issue draw calls and process game logic, capping the frame rate around 160-165 FPS regardless of resolution.

At Medium and High settings, the scaling is more linear. At High, the FPS goes from 138.6 (1080p) to 128.1 (1440p) to 107.3 (4K). This shows a balanced workload where both components are utilized. The GPU's 24 GB of VRAM and 960.0 GB/s bandwidth prevent any memory-related stutters, and the CPU's 12 threads are sufficient to maintain these frame rates. The data indicates that for this specific combo, the optimal balance of visual fidelity and frame rate is achieved at 1440p High, where the 128.1 FPS average is smooth and the system is not obviously bottlenecked by either component. Pushing to 4K Ultra yields 91.3 FPS, which is still playable but shows the CPU starting to lag behind the GPU's capabilities.

How This Combo Ranks

In the broader context of all tested configurations, this pairing of the Intel Core i5-10400F and AMD Radeon RX 7900 XTX achieves a rank of 380 out of 1,744 combos. This position in the 78th percentile of all tested systems indicates that while the combo is a high performer, it is not at the absolute top. The ranking is a composite measure that reflects the system's ability to maintain high frame rates across various settings and resolutions. The fact that it is not higher is directly attributable to the CPU. The GPU alone sits in the 85th percentile of all GPUs, but the CPU's 73rd percentile ranking drags the overall system score down. The data suggests that many of the 379 combos ranked above this one likely feature a newer, higher-performing processor paired with a similar or slightly less powerful GPU.

The rank of 380 reflects the GPU's raw power. The RX 7900 XTX's Passmark G3D score of 31,238 is substantial, and its 3DMark Steel Nomad DX12 score of 6,841 shows strong modern API performance. However, the CPU's Cinebench R23 multi-core score of 10,297 is modest for a gaming rig, and this is what prevents the combo from climbing higher. The deltaPct values for the CPU's rivals show that chips like the Intel Core i5-8500 are within 1.1% of the i5-10400F's average score, meaning the combo's ranking would not change significantly with a marginal CPU upgrade. To move up the ranks substantially, a processor with higher single-thread performance and more modern architecture would be required. The current rank of 380 is a solid, but not spectacular, result for a high-end GPU paired with a mid-range CPU.

GPU Role

The AMD Radeon RX 7900 XTX is the undisputed powerhouse of this configuration, and its role in Overpower is to provide overwhelming raw graphics throughput. With a boost clock of 2498 MHz and a game clock of 2365 MHz, the RDNA 3.0 architecture delivers exceptional compute performance. The GPU's 6,144 shading units, 384 TMUs, and 192 ROPs are top-tier figures, and its 61.39 TFLOPS of FP32 compute allows it to handle the most demanding effects with ease. The 24 GB of GDDR6 memory on a 384-bit bus provides 960.0 GB/s of bandwidth, which is crucial for high-resolution textures and is a key reason why the frame rates do not collapse at 4K. The GPU's 96 ray accelerators also suggest it is well-prepared for ray-traced workloads, even if the measured data in this pack does not specify them.

The GPU's benchmark results are consistent with its high-end status. Its average benchmark score of 44,019 places it in the 85th percentile of all GPUs, and its nearest rivals are other top-tier cards. The data shows that the RX 7900 XTX is not the limiting factor in this combo. At 1080p Low, the system achieves 165.9 FPS, but this is a CPU limit. When the CPU is not the bottleneck, such as at 4K Ultra, the GPU still delivers 91.3 FPS, evidence of its ability to process the massive pixel load. The Passmark DirectX 12 score of 131 is interesting, but the 3DMark Steel Nomad score of 6,841 is a better indicator of modern game performance, showing the card's strength in DX12 titles.

The GPU's role here is to provide headroom. In the resolution scaling data, we see that the GPU can handle even the most demanding settings without significant frame drops, indicating that it is not the primary constraint on system performance. The card's 355 W TDP and dual-slot design are physical realities, but they are not relevant to the benchmark scores. The data confirms that the RX 7900 XTX is a capable, high-performance component that is being held back by the i5-10400F in certain scenarios. The combo's rank of 380 is a direct result of this mismatch; the GPU is performing its role perfectly, but the CPU cannot keep up with its output in CPU-bound situations, particularly at lower resolutions and high frame rates.
