Doom

The AMD Ryzen 7 9850X3D paired with the NVIDIA GeForce RTX 5090 D delivers exceptional performance in Doom, ranking 2nd out of 3,712 tested combos. This data indicates a top-tier configuration where both components operate near their peak potential, though the scaling patterns reveal interesting nuances about where the bottleneck shifts as resolution increases.

Resolution Scaling

The measured FPS data shows a classic pattern of GPU-bound scaling, but with a twist. At 1080p High settings, this combo produces 357 FPS, rising to 485 FPS on Low settings. Moving to 1440p High drops the average to 231 FPS, a 35% reduction from the 1080p High result. At 4K High, the average falls further to 125 FPS, which represents a 65% decrease from 1080p High.

The scaling from 1440p to 4K is particularly revealing. At 1440p High, the system achieves 231 FPS, but at 4K High it drops to 125 FPS — a 46% performance hit. This substantial drop indicates the RTX 5090 D is becoming the limiting factor at higher resolutions, as the pixel throughput demands increase dramatically. The GPU's 104.8 TFLOPS FP32 compute and 1.79 TB/s memory bandwidth are being pushed harder at 4K, while the CPU has more headroom to feed frames.

At 1080p, the pattern suggests the CPU is starting to exert more influence. The jump from 357 FPS at High to 422 FPS at Medium (an 18% increase) and then to 485 FPS at Low (a 36% increase over High) shows that lowering settings provides proportionally larger gains at lower resolutions. This is typical behavior when the CPU begins to approach its frame-delivery ceiling; the Ryzen 7 9850X3D's 8 cores and 16 threads with a 5.60 GHz boost clock are strong, but even they have limits when pushing beyond 400 FPS.

The 1440p Medium row provides min/max data: 232 FPS minimum and 314 FPS maximum, with an average of 273 FPS. This spread of 82 FPS between minimum and maximum indicates some frame-time variance, though the minimum remains well above refresh-rate thresholds for most displays. Similarly, 1080p Medium shows a 359 FPS minimum and 486 FPS maximum, a 127 FPS spread that suggests the CPU is causing occasional frame pacing hiccups at extremely high frame rates.

Settings Recommendations

Analyzing the measured rows, the Medium preset offers the most balanced experience across all resolutions. At 1080p Medium, the combo delivers 422 FPS average with a 359 FPS minimum — the minimum is still vastly higher than any display refresh rate currently available. At 1440p Medium, 273 FPS average with a 232 FPS minimum keeps gameplay smooth even during intense scenes. At 4K Medium, 148 FPS average with a 126 FPS minimum remains comfortably above 120 Hz displays.

The High preset is the sensible choice for 4K gaming. At 125 FPS average, it provides excellent visual quality while maintaining high frame rates. The jump from High to Ultra at 4K costs 23 FPS (from 125 to 102), which is a significant 18% reduction for what is typically a marginal visual improvement in Doom's fast-paced action. For competitive play at 1440p or 1080p, the Low preset at 314 FPS (1440p) or 485 FPS (1080p) maximizes responsiveness, though the visual trade-offs may not be worth it for most players.

The Ultra preset at any resolution is hard to justify given the data. At 4K Ultra, the 102 FPS average is still playable, but it represents a 19% drop from High settings. At 1440p Ultra, 189 FPS is respectable, yet High delivers 231 FPS — a 42 FPS advantage. The pattern is consistent: High provides the best visual-to-performance ratio, with Medium as the fallback for players who prioritize frame rate consistency above all else.

How This Combo Ranks

This configuration holds the 2nd position out of 3,712 tested combos in Doom, placing it in the top 0.05% of all systems tested. This exceptional ranking reflects the synergy between the Ryzen 7 9850X3D and the RTX 5090 D, both of which sit at the 92nd percentile versus all CPUs and GPUs respectively.

The CPU's nearest rivals provide context for its contribution. The Intel Xeon Platinum 8260M scores nearly identically (deltaPct 0.1%), while the Intel Core i9-14900 trails by 0.5%. The AMD Ryzen AI 9 HX 470 leads by 0.7%. These sub-1% differences indicate the 9850X3D is operating at the very top of the CPU performance curve, though the margins are tight enough that other high-end processors could produce similar results in Doom.

For the GPU, the nearest rivals are surprising. The AMD Radeon RX 6650M XT scores 1.1% higher in average benchmark score, while the RX 6850M XT trails by 1.6%. The NVIDIA Tesla P100 variants show 2.1% and 2.4% deficits. These comparisons are based on aggregate benchmark scores rather than Doom-specific performance, so the RTX 5090 D's actual in-game advantage is likely larger given its 32 GB GDDR7 memory and 512-bit bus width.

The 2nd place ranking out of 3,712 combos means only one other CPU-GPU pairing produced higher average FPS in Doom. This could be attributed to either a slightly faster CPU for frame generation at low resolutions or a GPU with marginally better raw throughput. The data suggests that at 1080p, where CPU limits become apparent, another combination might edge ahead, but at 4K the RTX 5090 D's capabilities shine.

GPU Role

The RTX 5090 D's specifications directly influence its Doom performance. With 32 GB of GDDR7 memory on a 512-bit bus, the 1.79 TB/s bandwidth ensures texture streaming never becomes a bottleneck, even at 4K Ultra where memory demands peak. The 176 ROPs and 680 TMUs handle pixel processing efficiently, contributing to the 423.6 GPixel/s pixel rate and 1,636.8 GTexel/s texture rate.

The GPU's boost clock of 2407 MHz, running on the Blackwell 2.0 architecture with 104.8 TFLOPS FP32 compute, provides the raw horsepower needed for Doom's id Tech engine. The 170 RT cores and 680 tensor cores support advanced rendering features, though Doom's 2016 release date means it does not heavily utilize ray tracing or DLSS. The 5 nm process node and 92,200 million transistors indicate a highly efficient design that maintains high clock speeds under load.

The scaling data reveals the GPU's dominance at higher resolutions. At 4K, the performance difference between Low (170 FPS) and High (125 FPS) is 45 FPS, while at 1080p, the same settings gap is 128 FPS (485 vs 357). This indicates that at 4K, the GPU is the primary limiter, with settings changes having a proportionally smaller impact because pixel throughput saturates the GPU's capabilities. The 1.79 TB/s bandwidth becomes increasingly important at 4K, where memory access patterns are more demanding.

CPU Role

The Ryzen 7 9850X3D's specifications position it as a capable partner for the RTX 5090 D. Its 8 cores and 16 threads, based on the Zen 5 architecture with a 4.70 GHz base and 5.60 GHz boost clock, provide ample processing power for Doom's game logic and physics. The 96 MB of shared L3 cache is particularly beneficial for gaming workloads, as it reduces memory latency and improves data reuse patterns.

The CPU's benchmark results demonstrate its strength: 22,807 in Cinebench R23 multi-core and 2,228 in single-core, with a Passmark multithread score of 41,318. The 92nd percentile ranking versus all CPUs confirms it sits near the top of the desktop processor hierarchy. Its nearest rivals in aggregate scores show it competing within 0.7% of other high-end chips.

In Doom, the CPU's role becomes more apparent at lower resolutions. At 1080p High, the system produces 357 FPS, but at 1080p Low, it reaches 485 FPS — a 128 FPS increase from settings changes alone. This suggests that at lower resolutions, the CPU is capable of feeding frames faster than the GPU can render them at higher settings, but at Low settings, the GPU catches up and the CPU becomes the limiting factor. The 5.60 GHz boost clock and 8 high-performance cores are sufficient to maintain high frame rates, though the 359 FPS minimum at 1080p Medium indicates occasional CPU-bound dips.

The CPU's 120 W TDP and 4 nm process node from TSMC allow it to sustain high clocks without thermal throttling, which is crucial for maintaining consistent frame delivery in Doom's intense combat scenarios. The 89.6 GB/s memory bandwidth from dual-channel DDR5 support ensures the CPU can quickly access game data, complementing the GPU's 1.79 TB/s bandwidth for a balanced system.
