Overpower

The Intel Core i5-12400 paired with the AMD Radeon RX 7900 XTX delivers a compelling, high-refresh-rate experience in Overpower, though the data reveals a clear shift in bottleneck behavior as resolution increases. The measured frame rates show a system that is heavily GPU-limited at 4K, but whose performance ceiling at 1080p is increasingly defined by the processor's capabilities. Across all tested settings, the combination demonstrates a consistent ability to exceed 90 FPS, with the lower resolutions and settings pushing well past the 200 FPS mark, indicating a platform well-suited for competitive play.

Resolution Scaling

The performance drop from 1920x1080 to 3840x2160 is significant and reveals the expected progression of GPU-bound workload. At the "Low" preset, the average frame rate falls from 231.2 FPS at 1080p to 217.3 FPS at 1440p, and finally to 184.8 FPS at 4K. This represents an 20.1% reduction in performance from 1080p to 4K. The scaling pattern suggests that at 1080p, the RX 7900 XTX is not fully saturated, allowing the CPU to exert a greater influence on the final frame rate, which is typical for a high-end GPU paired with a mid-range processor.

The "Ultra" preset shows a different scaling curve. At 1080p, the average is 118.3 FPS, which drops to 107.1 FPS at 1440p, and then to 91.7 FPS at 4K. This is a 22.5% decrease from 1080p to 4K, which is a smaller relative drop than the "Low" preset. This indicates that as the graphical load increases, the GPU becomes the primary limiting factor, and the relative cost of rendering at higher resolutions is more evenly distributed. The data suggests that the i5-12400 can still feed the GPU adequately at 4K, as the frame rate scales with the increasing pixel count rather than hitting a hard CPU ceiling.

The gap between resolutions narrows at higher settings. For instance, the difference between 1080p and 1440p at "High" is 13.7 FPS (139.4 vs 125.7), while the difference between 1440p and 4K is 18.6 FPS (125.7 vs 107.1). This pattern indicates that the system's performance is becoming more dependent on the GPU's raw rendering power as the resolution climbs. The benchmark results imply that for players targeting 4K, the RX 7900 XTX is the definitive performance driver, while at 1080p, the CPU's single-threaded performance and memory bandwidth play a more critical role in achieving the highest possible frame rates.

GPU Role

The AMD Radeon RX 7900 XTX is the dominant component in this configuration, and its specifications align with the measured performance. With 24 GB of GDDR6 memory on a 384-bit bus, the GPU provides 960.0 GB/s of bandwidth, which is crucial for handling the high-resolution textures and geometry that Overpower likely presents at 4K. The boost clock of 2498 MHz and 6144 shading units provide the computational throughput necessary for the frame rates observed, particularly in the "Ultra" preset where the average drops to 91.7 FPS at 4K, a signal of the heavy workload.

The GPU's performance percentile of 85 places it well above the average GPU, and its benchmark scores reflect its high-end positioning. The Passmark G3D score of 31238 and Geekbench OpenCL score of 189573 indicate substantial raw compute capability. When compared to its nearest rivals, the data shows it performs within 2% of the NVIDIA GeForce RTX 4070 Ti, which is a notable reference point for its class. The GPU's role becomes more pronounced at higher resolutions and settings, where the frame rates are directly tied to its ability to process the increasing pixel and shading workload.

The 24 GB memory buffer is a key asset. In Overpower, the difference between the "Medium" and "High" presets at 4K is a drop from 117.3 FPS to 107.1 FPS, suggesting that the higher preset demands more memory bandwidth and capacity for additional effects and detail levels. The data shows that the GPU is the bottleneck at 4K in all presets, as the performance scales consistently with the graphical settings. The core clocks, with a base of 1929 MHz and a game clock of 2365 MHz, provide a stable performance envelope that allows the card to maintain high utilization without a significant performance drop-off between resolutions.

Settings Recommendations

Based on the measured average FPS, the "High" preset at 2560x1440 offers the most balanced experience for high-refresh-rate gaming. The 125.7 FPS average is well above the 100 FPS threshold for smooth gameplay, and it comes with a significant visual upgrade over the "Medium" preset, which runs at 138.4 FPS. The difference of 12.7 FPS between these two presets is relatively small, making the visual fidelity gains of "High" a worthwhile trade-off for most users.

For players prioritizing maximum frame rates, the "Low" preset at 1920x1080 is the clear choice, delivering an average of 231.2 FPS. This is ideal for competitive scenarios where response time is paramount. However, the jump to "Medium" at 1080p yields 154.6 FPS, a substantial 76.6 FPS drop, indicating that the "Low" preset is optimized for pure performance, likely by reducing shadow quality and post-processing effects. At 4K, the "High" preset's 107.1 FPS is the highest playable setting that maintains a triple-digit average, making it the recommended setting for users with 4K displays who want to stay above the 100 FPS mark.

The "Ultra" preset, while visually demanding, brings the system to its knees at 4K with a 91.7 FPS average. At 1440p, it achieves 107.1 FPS, which is identical to the "High" preset's 4K result. This suggests that the "Ultra" preset is best reserved for 1080p or 1440p gaming where the frame rate can remain in a comfortable range. The data indicates that the "High" preset is the sweet spot for this combination, providing a significant visual improvement over "Medium" while maintaining a high enough frame rate to fully utilize the capabilities of the i5-12400 and RX 7900 XTX across all resolutions.

Measured FPS Breakdown

At 1920x1080, the frame rates are consistently high across all settings. The "Low" preset averages 231.2 FPS, while "Medium" drops to 154.6 FPS. The "High" preset averages 139.4 FPS, and "Ultra" is the slowest at 118.3 FPS. This demonstrates a clear performance hierarchy, with the "Low" preset providing a 56.6% performance increase over the "Ultra" preset.

Moving to 2560x1440, the performance scales down as expected. The "Low" preset averages 217.3 FPS, a 13.9 FPS drop from 1080p. The "Medium" preset achieves 138.4 FPS, and "High" averages 125.7 FPS. The "Ultra" preset at 1440p yields 107.1 FPS, which is 11.2 FPS lower than at 1080p. The difference between "Low" and "Ultra" at this resolution is 110.2 FPS, highlighting the impact of graphical fidelity on performance.

At 3840x2160, the system remains highly capable, though the frame rates begin to approach the lower limits of high-refresh-rate gaming. The "Low" preset averages 184.8 FPS, which is a significant achievement for 4K. The "Medium" preset drops to 117.3 FPS, and "High" averages 107.1 FPS. The "Ultra" preset is the most demanding, with an average of 91.7 FPS. The data shows a 93.1 FPS difference between the "Low" and "Ultra" presets at 4K, indicating that the GPU is handling a massive workload increase at this resolution.
