Doom

# How This Combo Ranks

The AMD Ryzen 9 9900X3D paired with the AMD Radeon RX 7700 XT lands at rank 1054 out of 2930 tested combos in Doom, placing it in the 64th percentile of all combinations. That is a solidly above-average position, but not an elite one. The ranking suggests this pairing sits comfortably in the upper-middle tier of systems tested for this game, where the GPU's mid-range positioning is the primary anchor. The data shows a combo that is capable of high refresh rates at mainstream resolutions but does not threaten the top of the leaderboard where flagship GPUs dominate.

The rank of 1054 becomes more meaningful when viewed through the lens of the component-level percentiles. The CPU sits in the 91st percentile against all CPUs, while the GPU sits in the 67th percentile against all GPUs. This imbalance reveals that the processor is doing far more heavy lifting in the ranking than the graphics card. The combo's overall position at roughly the 64th percentile aligns much closer to the GPU's percentile than the CPU's, which indicates that in Doom, the graphics card is the limiting factor for how high this combo can climb. A stronger GPU in this same CPU slot would likely push the combo rank substantially higher, given the headroom the processor appears to offer.

# GPU Role

The AMD Radeon RX 7700 XT brings 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. For Doom, a game originally released in 2016, this memory configuration is more than sufficient for texture streaming and asset loading at any of the tested settings. The 12 GB capacity means that even at 4K Ultra settings, the game is unlikely to hit VRAM limits, allowing the GPU to focus its resources on rendering rather than memory management.

Clock speeds on this GPU are notable for their spread. The base clock runs at 1435 MHz, but the boost clock reaches 2544 MHz, with a game clock rated at 2171 MHz. That boost behavior matters in Doom because the game's engine can push GPU utilization high, allowing the card to sustain clocks closer to its boost ceiling. The measured frame rates reflect this: at 1080p Low, the card delivers 264 FPS average, which is a strong indicator that it is running near its maximum clock potential with minimal thermal or power throttling. The gap between base and boost clocks is over 1100 MHz, and the data suggests that in Doom, the card spends most of its time in the upper half of that range.

The GPU's compute specifications also play into its Doom performance. With 3456 shading units, 216 TMUs, and 96 ROPs, the card has a balanced configuration for a 1080p and 1440p focused part. The 35.17 TFLOPS of FP32 performance gives it substantial raw compute for the game's lighting and particle effects, while the 549.5 GTexel/s texture rate ensures that the detailed environments in Doom's later levels do not cause texture fetch bottlenecks. The pixel rate of 244.2 GPixel/s is a limiting factor at higher resolutions, which becomes evident when examining the resolution scaling data.

# Resolution Scaling

The measured FPS data reveals a clear and consistent scaling pattern across resolutions. At High settings, the average frame rate drops from 194 FPS at 1080p to 126 FPS at 1440p, then down to 68 FPS at 4K. That represents a 35% drop from 1080p to 1440p, and a further 46% drop from 1440p to 4K. The scaling is not linear, and the steeper decline at 4K points to the GPU becoming increasingly pixel-bound as resolution climbs.

At Low settings, the pattern is similar but with higher absolute numbers: 264 FPS at 1080p, 171 FPS at 1440p, and 93 FPS at 4K. The drop from 1080p to 1440p at Low settings is 35%, which is nearly identical to the High setting drop. However, the drop from 1440p to 4K at Low settings is 46%, the same percentage as High. This consistency across settings suggests that the scaling bottleneck is resolution-driven rather than settings-driven. The GPU's pixel throughput capabilities are the primary constraint at 4K, regardless of how light or heavy the rendering load is.

The Medium settings data includes min and max FPS values, providing additional insight into the scaling behavior. At 4K Medium, the average is 81 FPS with a min of 69 and max of 93. At 1440p Medium, the average jumps to 149 FPS with a min of 127 and max of 171. At 1080p Medium, the average reaches 230 FPS with a min of 196 and max of 265. The min-to-max spread widens proportionally with resolution, indicating that frame time variance scales with the rendering load. The 4K Medium min of 69 FPS is still above 60, but the margin is thinner than at lower resolutions, suggesting that demanding scenes at 4K could potentially dip below that threshold.

# Measured FPS Breakdown

At 1080p, the data shows a full range of performance across settings. Low settings produce an average of 264 FPS, which is exceptionally high and likely beyond the refresh rate of most monitors. Medium settings average 230 FPS, with a min of 196 and max of 265. High settings average 194 FPS, and Ultra settings average 159 FPS. The progression from Low to Ultra shows a 40% reduction in average FPS, but even at Ultra, the 159 FPS average is well above the 144 Hz refresh rate that many competitive gamers target.

At 1440p, the performance remains strong but begins to show the GPU's limits. Low settings average 171 FPS, which is still very high. Medium settings average 149 FPS, with a min of 127 and max of 171. High settings average 126 FPS, and Ultra settings drop to 103 FPS. The drop from High to Ultra at 1440p is only 18%, which is smaller than the 22% drop from High to Ultra at 1080p. This suggests that at 1440p, the GPU is starting to become the limiting factor, and the additional rendering work from Ultra settings has less relative impact because the pixel load is already significant.

At 4K, the performance drops into more moderate territory. Low settings average 93 FPS, Medium settings average 81 FPS, High settings average 68 FPS, and Ultra settings average 56 FPS. The Ultra setting at 4K is the only tested configuration that falls below 60 FPS, and the data shows no min or max values for that row, which may indicate that the frame rate was consistently in the mid-50s. The gap between Low and Ultra at 4K is 40%, which is the same percentage drop as at 1080p, but the absolute impact is much larger because the starting point is lower.

# Settings Recommendations

The measured data suggests that the optimal settings depend heavily on the target resolution and refresh rate. At 1080p, even Ultra settings deliver 159 FPS average, which is sufficient for high-refresh monitors. The data indicates that players with 144 Hz displays could comfortably use Ultra at 1080p and still maintain frame rates above the refresh ceiling. For 240 Hz displays, High settings at 194 FPS would be the better choice, as the 35 FPS gain from dropping from Ultra to High is meaningful for competitive play.

At 1440p, the recommendation becomes more nuanced. Ultra settings at 103 FPS are playable on 100 Hz displays but would leave performance on the table for 144 Hz monitors. High settings at 126 FPS provide a better balance, offering a 22% FPS increase over Ultra while maintaining most of the visual fidelity. The data shows that Medium settings at 149 FPS would be the choice for 144 Hz displays, but the visual trade-off from High to Medium is more noticeable. For most players at 1440p, High settings appear to be the sweet spot, delivering 126 FPS with the game's more demanding visual features intact.

At 4K, the options are more constrained. Ultra settings at 56 FPS are below the 60 FPS threshold and would likely result in noticeable stutter on standard 60 Hz displays. High settings at 68 FPS provide a comfortable margin above 60 FPS and are the recommended choice for 4K play. Medium settings at 81 FPS would be preferable for those who prioritize frame rate over visual quality, but the jump from High to Medium is a significant visual downgrade for only a 19% FPS gain. Low settings at 93 FPS are available but would strip away much of the game's visual identity, which seems unnecessary given that High settings already achieve a playable frame rate.

# CPU Role

The AMD Ryzen 9 9900X3D is a 12-core, 24-thread processor based on the Zen 5 architecture, built on a 4 nm process at TSMC. It has a base clock of 4.40 GHz and a boost clock of 5.50 GHz, with a 120 W TDP. The CPU's cache configuration is substantial: 80 KB of L1 per core, 1 MB of L2 per core, and a large 128 MB of L3 cache. This cache structure is particularly relevant for gaming, as Doom's engine benefits from data being readily available in the fast L3 cache rather than having to fetch from main memory.

In the context of Doom's measured FPS, the CPU's role is best understood by examining the frame rates at lower resolutions where the GPU is less stressed. At 1080p Low settings, the combo achieves 264 FPS average. At 1080p Ultra settings, it achieves 159 FPS average. The fact that the frame rate scales down as settings increase, even at the same resolution, indicates that the GPU is doing more work per frame. However, the CPU must be capable of issuing draw calls and managing game logic fast enough to keep the GPU fed. The data showing 264 FPS at 1080p Low suggests the CPU is not a bottleneck at this resolution, as the GPU is still the component determining the frame rate ceiling.

The CPU's single-thread performance, as measured by benchmarks, is strong. The 3DMark single-thread score of 1269 and Cinebench R23 single-core score of 6739 indicate that the processor has excellent per-core performance, which matters for Doom's primary game thread. The multi-thread scores are also high, with Cinebench R23 multicore at 47737 and Geekbench multicore at 22884, but Doom is not heavily multi-threaded, so the single-thread strength is more relevant for maintaining high frame rates.

The CPU's 91st percentile ranking against all CPUs, combined with the GPU's 67th percentile, reinforces the conclusion that this processor has ample headroom for the RX 7700 XT. The benchmark data shows the CPU is closer in performance to much stronger processors, such as the Intel Core Ultra 5 245KF which scores only 0.6% higher on average, than it is to weaker ones. This means that for Doom, the CPU is unlikely to ever be the limiting factor in this combo, even at 1080p with the lowest settings where the GPU has the least work to do. The processor's 24 threads and high clock speeds provide more than enough computational throughput for the game's demands, leaving the GPU as the clear performance ceiling for this pairing.
