Doom

The AMD Ryzen 7 7800X3D paired with the AMD Radeon RX 6600 lands at rank 1374 out of 1681 tested combos in Doom. That places this configuration in the bottom quarter of all measured systems, a surprising outcome given the components involved. The data suggests this is not a pairing that maximizes the potential of either part in this specific title. The ranking implies that while the hardware is capable, the combination does not translate into a top-tier experience for this game, with many other CPU-GPU pairings delivering higher average frame rates.

How This Combo Ranks

The combo rank of 1374 out of 1681 indicates that this system performs in the lower 18th percentile of all tested configurations for Doom. This is a notable finding because the individual components do not appear weak on paper. The CPU is a high-end desktop part, and the GPU is a capable mid-range offering. Yet, the measured results show that most other combinations in the database produce higher frame rates. The data implies a significant bottleneck, likely on the graphics side, preventing the strong processor from fully flexing its capabilities. For context, being 307 positions from the bottom means there is a substantial number of slower systems, but the sheer volume of faster ones highlights a performance ceiling that is lower than many users would expect from this hardware.

GPU Role

The AMD Radeon RX 6600 is the primary contributor to the frame rate limits observed in the measured data. Its 8 GB of GDDR6 memory on a 128-bit bus provides 224.0 GB/s of bandwidth. The GPU has a base clock of 1626 MHz, a game clock of 2044 MHz, and a boost clock of 2491 MHz. These specifications are modest by current standards, and the benchmark results confirm that this is where the system’s performance is capped. The GPU’s percentile rank against all other graphics cards is 69, meaning it performs better than 69% of the tested GPUs. However, its nearest rivals include the AMD Radeon 890M with a deltaPct of 0, and the AMD Radeon RX 580 2048SP with a deltaPct of -0.2, showing it is closely matched with older or integrated solutions. The data shows that the RX 6600’s raw compute power, listed at 8.928 TFLOPS FP32, is sufficient for playable frame rates at lower settings but struggles to maintain high performance when graphical demands increase.

CPU Role

The AMD Ryzen 7 7800X3D is a formidable processor that is not the limiting factor in this pairing. It features 8 cores and 16 threads based on the Zen 4 architecture, with a base clock of 4.20 GHz and a boost clock of 5.00 GHz. Its large 96 MB of shared L3 cache is a key asset for gaming. The CPU’s benchmark scores are strong, such as a Cinebench R23 multicore score of 29149 and a Geekbench single-core score of 2725. Its percentile rank against all CPUs is 87, and it is nearly identical in performance to its nearest rival, the Intel Core i7-12700F, with a deltaPct of 0.1. In Doom, the CPU’s role is to feed the GPU with draw calls and physics data. Given the high frame rates seen at 1080p Low, the CPU is clearly capable of handling the game’s logic. The bottleneck is not the processor’s ability to compute but rather the GPU’s inability to render frames fast enough to keep up with what the CPU can provide.

FAQ

Q: Why is the combo ranked so low if the CPU is powerful?

A: The ranking reflects the combined performance. While the Ryzen 7 7800X3D is a high-percentile CPU, the Radeon RX 6600 is a mid-range GPU that limits the overall frame rate. The data shows that this combination does not reach the performance levels of other pairings with faster graphics cards, consequently placing it at rank 1374 out of 1681.

Q: How does the RX 6600 compare to its closest rivals in the database?

A: The RX 6600’s average benchmark score is 25235. Its nearest rival, the AMD Radeon 890M, has an average score of 25246, resulting in a deltaPct of 0. The AMD Radeon RX 580 2048SP scores 25287, which is a deltaPct of -0.2, indicating the RX 6600 is slightly slower. The data shows these GPUs are essentially performance peers.

Q: What is the best frame rate this combo can achieve in Doom?

A: The highest average FPS recorded is 173.5 at 1920x1080 resolution with Low settings. This is the only configuration where the system approaches high refresh rate territory. All other settings and resolutions result in lower average frame rates.

Q: Is the CPU or GPU the limiting factor at 4K resolution?

A: The data indicates the GPU is the limiting factor. At 3840x2160 with Ultra settings, the average FPS drops to 36.4. Even at Low settings, the 4K average FPS is only 60.9. The CPU has ample headroom, but the RX 6600’s 8 GB of VRAM and bandwidth are insufficient for high-resolution rendering.

Q: Does the CPU’s performance vary significantly across different benchmark tests?

A: Yes, the CPU shows variability. For instance, its PassMark single-thread score is 3759, while its Cinebench R23 multi-core score is 29149. These scores reflect different workloads, but both are strong. The data suggests the CPU is well-rounded, but its performance in Doom is not the primary constraint on frame rate.

Q: How does the GPU’s memory configuration affect Doom’s performance?

A: The GPU has 8 GB of GDDR6 memory with 224.0 GB/s of bandwidth. In Doom, this is a limiting factor at higher resolutions and settings. The 4K Ultra average FPS is 36.4, which is likely due to the memory bandwidth and capacity being saturated, whereas at 1080p Low, the demand is lower and the average FPS is 173.5.

Resolution Scaling

The measured FPS data reveals a clear pattern of how performance scales with resolution. At 1920x1080, the system is capable of high frame rates, with an average of 173.5 FPS on Low settings. Moving to 2560x1440, the same Low settings average drops to 113.4 FPS, a significant reduction. At 3840x2160, the Low settings average falls to 60.9 FPS. This scaling pattern shows that the GPU is the primary bottleneck as resolution increases. The frame rate drop from 1080p to 1440p is 60.1 FPS, and from 1440p to 4K is 52.5 FPS. The data suggests that the RX 6600’s compute and memory resources are exhausted as the pixel count rises, leading to a nearly linear decline in performance. The CPU’s performance remains constant, so the system’s behavior is entirely dictated by the GPU’s rendering capabilities.

Settings Recommendations

The measured data points to a clear trade-off between visual fidelity and frame rate. For a smooth experience, the Low settings at 1920x1080 offer the highest average FPS of 173.5, which is ideal for competitive play. However, this comes at the cost of visual quality. The Medium settings at 1080p yield an average FPS of 153.2, which is still very playable and offers a better balance. At 1440p, the Medium settings produce an average FPS of 101.4, which is acceptable for most users. The High settings at 1440p result in an average of 84.3 FPS, which is playable but not ideal for high refresh rate monitors. The Ultra settings should be avoided at all resolutions except perhaps 1080p, but even there, the 103.6 FPS average is lower than what Medium provides. The data suggests that Medium settings provide the best experience, offering a significant visual upgrade over Low while maintaining average frame rates above 100 FPS at 1080p and above 100 FPS at 1440p.

Measured FPS Breakdown

The following table details the exact measured average FPS for each resolution and settings combination.

| Resolution | Settings | Average FPS |

| :--------- | :------- | ----------: |

| 1920x1080 | Low | 173.5 |

| 1920x1080 | Medium | 153.2 |

| 1920x1080 | High | 131.9 |

| 1920x1080 | Ultra | 103.6 |

| 2560x1440 | Low | 113.4 |

| 2560x1440 | Medium | 101.4 |

| 2560x1440 | High | 84.3 |

| 2560x1440 | Ultra | 66.8 |

| 3840x2160 | Low | 60.9 |

| 3840x2160 | Medium | 53.9 |

| 3840x2160 | High | 43.3 |

| 3840x2160 | Ultra | 36.4 |

The data shows that the most significant performance drop occurs when moving from 1080p to 1440p, with the Low settings average FPS falling by 60.1. The progression from Low to Ultra at each resolution also shows a consistent reduction in frame rate, with the Ultra preset averaging roughly 40% lower FPS than Low at the same resolution. This quantifies the GPU’s workload and confirms that the RX 6600 is the decisive factor in this combo’s performance.
