Doom

# How This Combo Ranks

This AMD Ryzen 7 9850X3D + AMD Radeon RX 6800 XT combination sits at rank 866 out of 2930 tested combos for Doom, placing it in the 70th percentile of all tested systems. That is a solidly above-average position, but not a top-tier one. The data suggests this pairing is capable of delivering high frame rates across most settings, yet it is not among the elite configurations for this title.

The rank of 866 out of 2930 means roughly 2064 other combinations performed worse, while about 865 performed better. This positions the combo in the upper-middle tier of the database. The CPU alone achieves a percentile rank of 92 against all CPUs, while the GPU sits at an 85th percentile against all GPUs. The gap between these two percentile figures hints that the GPU is the more limiting factor in this pairing, a pattern that becomes clearer when examining the measured FPS across resolutions.

What is striking is that the CPU's average benchmark score of 58386 places it within 0.1% of the Intel Xeon Platinum 8260M, which scores 58323, and within 0.2% of the Intel Xeon w5-2545 at 58504. The GPU's average score of 48477 is 1.5% above the NVIDIA RTX A1000 Mobile at 47743, but 3% behind both the Intel Arc A550M at 49737 and the NVIDIA GeForce RTX 5070 Ti at 49957. These close margins mean that in a game like Doom, which is known for its optimization, the combo's rank is determined more by the balance between CPU and GPU than by any single component's raw dominance.

GPU Role

The AMD Radeon RX 6800 XT brings 16 GB of GDDR6 memory on a 256-bit bus, with a bandwidth of 512.0 GB/s. Its memory clock runs at 2000 MHz, translating to 16 Gbps effective. The GPU's base clock is 1825 MHz, with a game clock of 2015 MHz and a boost clock of 2250 MHz. These clock speeds are substantial, and the 512 GB/s bandwidth is generous for a card of this class.

In Doom, the GPU's role is evident in the scaling from Low to Ultra settings. At 3840x2160, the average FPS drops from 102 on Low to 62 on Ultra, a 39% reduction. At 2560x1440, the drop is from 189 on Low to 114 on Ultra, a 40% reduction. At 1920x1080, the drop is from 292 on Low to 176 on Ultra, a 40% reduction. This consistent percentage decline across resolutions indicates that the GPU is handling the graphical workload uniformly, with settings having a proportional impact on frame rate.

The GPU's 85th percentile rank against all GPUs, combined with its average benchmark score of 48477, suggests it is a capable performer for this game. The 16 GB VRAM is more than sufficient for Doom, even at 4K Ultra, where the data shows an average of 62 FPS. The 72 ray tracing cores and 4608 shading units contribute to the card's ability to maintain playable frame rates at high settings, though the data does not isolate their individual contributions.

Notably, the GPU's nearest rival, the NVIDIA RTX A1000 Mobile, scores only 1.5% lower on average, while the Intel Arc A550M and NVIDIA GeForce RTX 5070 Ti score 2.5% and 3% higher, respectively. This tight clustering means the RX 6800 XT is competitive but not dominant. In practice, the 4K Ultra result of 62 FPS is exactly at the edge of smooth playability, suggesting the GPU is the bottleneck at that resolution and setting combination.

CPU Role

The AMD Ryzen 7 9850X3D is an 8-core, 16-thread processor based on Zen 5 architecture, built on a 4 nm process. Its base clock is 4.70 GHz, boosting to 5.60 GHz. The 96 MB of shared L3 cache is a defining feature, likely benefiting games that rely on large working sets. The CPU's TDP is 120 W, and it supports DDR5 memory with a dual-channel bus, delivering 89.6 GB/s of bandwidth.

The CPU's benchmark results show a strong single-thread score of 4704 in Passmark, with a multithread score of 41318. In Cinebench R23, it achieves 22807 multi-core and 2228 single-core. These numbers place the CPU at a 92nd percentile rank against all CPUs, with an average benchmark score of 58386. Against its nearest rivals, it is virtually tied with the Intel Xeon Platinum 8260M (0.1% ahead) and the Intel Xeon w5-2545 (0.2% behind), while being 0.5% ahead of the Intel Core i9-14900 and 0.7% behind the AMD Ryzen AI 9 HX 470.

In Doom, the CPU's role is less visible than the GPU's, but it is still critical. At 1080p Low, the combo achieves 292 FPS, which is a very high frame rate that demands strong single-thread performance. The 5.60 GHz boost clock and the large L3 cache likely help maintain high minimum frame rates, though the data only provides min FPS for Medium settings: 216 at 1080p, 140 at 1440p, and 76 at 4K. The CPU's 8 cores and 16 threads are more than adequate for Doom, which is not a heavily threaded title, but the high clock speeds ensure that the GPU is fed with enough data to reach its potential.

Measured FPS Breakdown

The measured FPS data provides a comprehensive picture. At 1920x1080, the combo delivers 292 FPS on Low, 254 FPS on Medium, 215 FPS on High, and 176 FPS on Ultra. The Medium setting includes a min FPS of 216 and a max of 292, indicating consistency. At 2560x1440, the results are 189 FPS on Low, 165 FPS on Medium, 139 FPS on High, and 114 FPS on Ultra. The Medium setting at this resolution shows a min of 140 and a max of 189. At 3840x2160, the results drop to 102 FPS on Low, 89 FPS on Medium, 75 FPS on High, and 62 FPS on Ultra. The Medium setting at 4K has a min of 76 and a max of 103.

These numbers reveal a clear pattern. At 1080p, every setting exceeds 170 FPS, which is beyond the refresh rate of most monitors. The step from Low to Ultra costs 116 FPS, a 40% reduction. At 1440p, the spread is from 189 to 114 FPS, a 40% reduction as well. At 4K, the spread is from 102 to 62 FPS, also a 40% reduction. This uniformity suggests that the performance scaling is consistent across resolutions, with the GPU being the primary driver of the differences.

The 4K Ultra result of 62 FPS is the only setting where the combo dips below 60 FPS, though it is close. The 4K High setting at 75 FPS is more comfortable, and 4K Medium at 89 FPS is very playable. The data indicates that this combo can handle 4K gaming, but only if the user is willing to adjust settings below Ultra.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution. At 1920x1080, the combo delivers 254 FPS on Medium and 215 FPS on High. Even at Ultra, it maintains 176 FPS, which is well above the refresh rate of most monitors. For 1080p users, Ultra is recommended, as the performance penalty is minimal and the visual quality is maximized.

At 2560x1440, the High setting at 139 FPS offers a good balance. The Ultra setting at 114 FPS is still smooth, but the 25 FPS gain from dropping to High is noticeable for fast-paced action. Medium at 165 FPS is the choice for competitive play, but High provides the best visual-to-performance ratio.

At 3840x2160, the situation changes. Ultra at 62 FPS is borderline, while High at 75 FPS offers more headroom. Medium at 89 FPS is the recommended setting for 4K, as it provides a comfortable margin above 60 FPS while still delivering good visual quality. Low at 102 FPS is available for those prioritizing frame rate, but the visual compromise is significant.

The data suggests that the combo is capable of running Doom at high settings across all resolutions, but users should be prepared to drop to Medium or High at 4K to ensure consistent performance. The 4K Ultra result of 62 FPS is technically playable, but the min FPS data for Medium (76 FPS) suggests that Ultra might have lower minimums, which could cause stutters in demanding scenes.

Resolution Scaling

The FPS drop from 1080p to 4K is significant and reveals the limiting component. At 1920x1080, the combo averages 215 FPS on High. At 2560x1440, this drops to 139 FPS, a 35% reduction. At 3840x2160, it falls to 75 FPS, a further 46% reduction from 1440p. The total drop from 1080p to 4K is 65%, from 215 to 75 FPS.

This scaling pattern is typical of a GPU-bound scenario. The CPU's high single-thread performance (4704 Passmark single-thread score) and 5.60 GHz boost clock ensure that even at 1080p Low (292 FPS), the CPU is not the bottleneck. As resolution increases, the GPU's workload grows, and the FPS drops accordingly. The GPU's 512 GB/s bandwidth and 16 GB VRAM are sufficient for 4K, but the raw compute power (20.74 TFLOPS FP32) limits performance at that resolution.

The data shows that the combo is more capable at 1440p than at 4K relative to other settings. At 1440p High, the FPS of 139 is 64% of the 1080p High result of 215. At 4K High, the FPS of 75 is 35% of the 1080p result. This indicates that the GPU's performance scales roughly with pixel count, confirming that it is the primary limiter at higher resolutions. For users seeking maximum frame rates, 1080p is the clear choice, while 1440p offers a balanced experience, and 4K requires setting adjustments to maintain playability.
