How This Combo Ranks

The combo’s rank of 1080 out of 1681 tested combinations indicates a solid mid-to-upper tier position. This is not a top-tier combination, but it is far from a low-end one. The data suggests that this pairing is well-suited for high-refresh-rate gaming at 1080p and capable of smooth 1440p gameplay. The percentile placement implies that roughly 64% of tested combos outperform it, but this does not tell the full story. The measured FPS figures show that the actual gaming experience is strong, especially when considering the game’s age and optimization.

The CPU’s average benchmark score of 31580 places it in the 87th percentile of all CPUs. Its nearest rivals are all within a 0.6% delta, showing that the 7800X3D is a high-performing processor. The 8-core, 16-thread configuration with a boost clock of 5.00 GHz and 96 MB of L3 cache is a potent combination for gaming. The GPU, with a score of 29024 and a 72nd percentile ranking, is a capable mid-range part. Its nearest rivals, such as the AMD Radeon RX 6800M and Intel Arc A370M, are within a 0.6% delta. This shows that the GPU is competitive within its class. In the context of Doom, the rank is a result of the GPU’s performance ceiling at higher settings, while the CPU ensures that frame rates remain high when the GPU is not the bottleneck.

GPU Role

The AMD Radeon RX 6650 XT is central to this combo’s performance in Doom. The GPU’s 8 GB of GDDR6 memory is sufficient for this title, even at 4K with High settings, as the measured 50 FPS average indicates. The 128-bit memory bus and 280.3 GB/s bandwidth provide enough throughput for the game’s textures and geometry. The GPU’s boost clock of 2635 MHz is the highest of its three clock states, with a game clock of 2410 MHz and a base clock of 2055 MHz. These clocks, combined with 2048 shading units and 64 ROPs, drive the pixel rate of 168.6 GPixel/s and texture rate of 337.3 GTexel/s.

The GPU’s FP32 performance is 10.79 TFLOPS, which is a measure of its raw compute capability. In Doom, this translates to the ability to maintain high frame rates at 1080p and 1440p. The data shows that at 2560x1440 with Ultra settings, the average FPS is 77.1, which is a demanding scenario. At 1080p with Low settings, the GPU is able to push an average of 201.6 FPS, showing that the GPU is not a limiting factor at lower settings. However, at 4K with Ultra settings, the average FPS drops to 41.9, indicating that the GPU’s memory bandwidth and compute power are being stressed. The GPU’s percentile ranking of 72nd versus all GPUs suggests it is a competent performer, but for a fast-paced FPS like Doom, the 4K Ultra setting is not ideal, as the frame rate dips below 45 FPS.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings. At 1920x1080, the combo achieves 201.6 FPS on Low, 177 FPS on Medium, 144.3 FPS on High, and 117.4 FPS on Ultra. These numbers show a clear scaling pattern: as settings increase, frame rates decrease, but all remain above 115 FPS. This is an excellent result for a 1080p gamer seeking high refresh rates.

Moving to 2560x1440, the averages are 128.3 FPS on Low, 116 FPS on Medium, 97.8 FPS on High, and 77.1 FPS on Ultra. The drop from Low to Ultra is significant, but even the lowest figure of 77.1 FPS is well within the playable range for most users. The data shows that 1440p is the sweet spot for this combo, balancing visual quality and performance. At 3840x2160, the averages are 70.7 FPS on Low, 61.2 FPS on Medium, 50 FPS on High, and 41.9 FPS on Ultra. The 4K results are more varied, with Low settings providing a smooth experience, but Ultra settings falling below 45 FPS, which may be less desirable for a fast-paced shooter.

The progression from Low to Ultra at each resolution shows a consistent penalty. At 1080p, the difference between Low and Ultra is 84.2 FPS, or roughly 42%. At 1440p, the difference is 51.2 FPS, or about 40%. At 4K, the difference is 28.8 FPS, or 41%. This suggests that the settings impact is relatively consistent across resolutions, though the absolute frame rates are lower at higher resolutions.

Resolution Scaling

The FPS drops from 1080p to 4K reveal important information about the limiting component. At Low settings, the average FPS drops from 201.6 at 1080p to 128.3 at 1440p, and then to 70.7 at 4K. This represents a 36% drop from 1080p to 1440p, and a further 45% drop from 1440p to 4K. The total drop from 1080p to 4K is 65%. At Ultra settings, the drop is from 117.4 at 1080p to 77.1 at 1440p, and then to 41.9 at 4K. This is a 34% drop from 1080p to 1440p, and a 46% drop from 1440p to 4K, with a total drop of 64%.

These percentages are telling. The consistent reduction of roughly one-third from 1080p to 1440p, and then nearly half from 1440p to 4K, indicates that the GPU is the primary scaling bottleneck. The CPU, with its high single-thread performance and large cache, is not the limiting factor in these scenarios. The data shows that moving from 1080p to 1440p increases the pixel count by 78%, while moving to 4K increases it by 125% from 1440p. The observed FPS drops are less than the pixel count increases, suggesting that the GPU is not purely pixel-bound and that other factors, such as memory bandwidth, play a role. The RX 6650 XT’s 280.3 GB/s bandwidth is likely a contributor to the scaling behavior. The fact that the FPS drops are similar across all settings indicates that the GPU is consistently the limiting component, regardless of the graphical load.

CPU Role

The AMD Ryzen 7 7800X3D plays a crucial role in ensuring that the GPU can perform to its potential. The CPU has 8 cores and 16 threads, with a base clock of 4.20 GHz and a boost clock of 5.00 GHz. The 96 MB of shared L3 cache is a key feature, as it reduces latency and improves game performance. The CPU’s benchmark scores are strong, with a Cinebench R23 multicore score of 29149 and a single-core score of 4115. The Geekbench multicore score is 15101, and the single-core score is 2725.

In Doom, the CPU’s performance is sufficient to avoid bottlenecking the GPU at most settings. The data shows that at 1080p with Low settings, the combo achieves 201.6 FPS, which is a high frame rate that requires a capable CPU. The 3DMark 16-thread score of 7980 and the 8-thread score of 6539 indicate strong multi-threaded performance, which is beneficial for games that use multiple cores. The CPU’s percentile ranking of 87th versus all CPUs confirms its high-end status. The nearest rivals, such as the Intel Core i7-12700F, are within a 0.1% delta, showing that the 7800X3D is a top-tier processor for this metric.

The CPU’s role becomes more apparent at lower resolutions and settings, where the GPU has less work to do. At 1080p Low, the 201.6 FPS average suggests that the CPU is keeping up with the GPU’s output. The single-thread performance, as measured by the 3DMark single-thread score of 959 and the Cinebench R23 single-core score of 4115, is critical for this game’s engine. The CPU’s 5.00 GHz boost clock ensures that single-threaded workloads are handled efficiently. The 120 W TDP is a reasonable power envelope for this level of performance. The data shows that the CPU is not a limiting factor in any of the tested configurations, as the FPS scaling pattern is consistent with a GPU-bound scenario. The CPU’s 87th percentile ranking and its high benchmark scores demonstrate that it is a capable partner for the RX 6650 XT in Doom.
