Doom

AMD Ryzen 7 9850X3D and NVIDIA GeForce RTX 5090 pairing delivers exceptional performance in Doom, ranking in the 98.5th percentile of all tested combinations. The data shows a system capable of pushing even 4K Ultra settings well past 60 FPS, with lower resolutions reaching refresh rates that exceed the capabilities of most displays. This analysis walks through the CPU and GPU contributions, scaling behavior, and practical settings guidance based solely on measured results.

CPU Role

The AMD Ryzen 7 9850X3D provides the foundation for this system’s high frame rates. With 8 cores and 16 threads, the processor operates at a base clock of 4.70 GHz and boosts to 5.60 GHz. This clock speed advantage is significant for Doom’s engine, which relies on strong per-core performance for game logic and draw call processing. The 96 MB of shared L3 cache further aids performance by keeping frequently accessed data close to the cores, reducing memory latency during intense combat scenarios.

Benchmark data confirms the CPU’s strength. In Cinebench R23 multi-core testing, the processor scores 22807 points, while single-core performance reaches 2228 points. PassMark single-thread testing yields a score of 4704, placing the chip in the 92nd percentile of all CPUs. The CPU’s nearest rivals in average benchmark score include the Intel Xeon Platinum 8260M at 58323 (0.1% higher), the Intel Xeon w5-2545 at 58504 (0.2% lower), the Intel Core i9-14900 at 58115 (0.5% higher), and the AMD Ryzen AI 9 HX 470 at 58826 (0.7% lower). These margins are negligible, indicating the 9850X3D sits at the top tier of desktop processors.

For Doom specifically, the CPU’s role becomes more pronounced at lower resolutions. At 1080p, frame rates reach 454 FPS on Low settings, which demands the CPU to feed frames as fast as the GPU can render them. The 5.60 GHz boost clock provides the headroom needed for such extreme frame rates. The processor’s 120 W TDP and Zen 5 architecture on a 4 nm process node from TSMC ensure sustained performance without thermal throttling, though the data does not include thermal measurements to confirm this directly.

The motherboard interface uses AMD Socket AM5 with PCIe Gen 5 support across 24 CPU lanes, providing ample bandwidth for the GPU and NVMe storage. Memory support includes DDR5 with dual-channel configuration and 89.6 GB/s bandwidth, which is sufficient for gaming workloads. ECC memory support is present, though its impact on gaming performance is minimal. The integrated Radeon Graphics can serve as a fallback display output, but the discrete RTX 5090 handles all rendering duties in this configuration.

GPU Role

The NVIDIA GeForce RTX 5090 is the primary driver of Doom’s visual output, and its specifications are substantial. The GPU features 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth. This memory configuration is overkill for Doom, which was released in 2016 and does not require such capacity, but it ensures no texture streaming bottlenecks at any resolution or settings combination. The GPU’s clock speeds are 2017 MHz base and 2407 MHz boost, with memory operating at 1750 MHz (28 Gbps effective).

Compute resources are equally impressive: 21760 shading units, 680 texture mapping units, and 176 render output units. The 170 RT cores and 680 tensor cores handle ray tracing and AI workloads, though Doom’s original release does not utilize ray tracing. The GPU achieves 104.8 TFLOPS of FP32 performance and a pixel rate of 423.6 GPixel/s, which translates to rapid frame rendering even at 4K resolution.

GPU benchmarks place the RTX 5090 in the 92nd percentile of all GPUs. Its average benchmark score of 79842 compares closely with the NVIDIA Tesla P100 PCIe 16 GB at 79605 (0.3% higher), the NVIDIA Tesla P100 PCIe 12 GB at 79396 (0.6% higher), the AMD Radeon RX 6850M XT at 78940 (1.1% higher), and the AMD Radeon Pro Vega 64X at 80959 (1.4% lower). These rival comparisons are notable because the Tesla P100 and Radeon Pro Vega 64X are professional or workstation cards, highlighting how the RTX 5090’s gaming performance aligns with top-tier compute hardware.

In Doom, the GPU’s role scales with resolution. At 4K, the GPU becomes the limiting factor, as evidenced by frame rates dropping from 334 FPS at 1080p High to 117 FPS at 4K High. The 32 GB VRAM ensures that even Ultra settings at 4K do not exceed memory capacity, as Doom’s texture requirements are modest by modern standards. The GPU’s 575 W TDP and dual-slot design require a 950 W suggested PSU, but the data does not include power consumption measurements during gameplay.

Resolution Scaling

The measured FPS data reveals clear scaling patterns across resolutions. At 1080p, the system achieves 454 FPS on Low settings, 396 FPS on Medium, 334 FPS on High, and 273 FPS on Ultra. Moving to 1440p, these figures drop to 294 FPS Low, 256 FPS Medium, 216 FPS High, and 177 FPS Ultra. At 4K, the numbers decline further to 159 FPS Low, 139 FPS Medium, 117 FPS High, and 96 FPS Ultra.

The percentage drops between 1080p and 4K are substantial. For Low settings, the drop from 454 to 159 FPS represents a 65% reduction. Medium settings fall from 396 to 139 FPS, a 65% reduction. High settings decline from 334 to 117 FPS, a 65% reduction. Ultra settings see the smallest relative drop, from 273 to 96 FPS, a 65% reduction as well. The consistency of this 65% reduction across all settings suggests a uniform GPU-bound scaling pattern.

This uniform scaling indicates that the GPU is the primary limiting component at all resolutions. The CPU’s 8 cores and 16 threads provide sufficient processing power even at 1080p Low, where frame rates exceed 450 FPS. The RTX 5090’s rendering workload scales with pixel count, and the 4K resolution quadruples the pixel count compared to 1080p, which accounts for the observed frame rate reductions. The CPU does not become a bottleneck at any tested configuration, as evidenced by the linear relationship between resolution and frame rate.

The 1440p results show intermediate performance, with Medium settings providing 256 FPS and min FPS of 218, while max FPS reaches 295. The 4K Medium settings similarly show a min FPS of 118 and max FPS of 160, indicating some frame time variance but no severe stuttering. The lack of min and max FPS data for Low, High, and Ultra settings at most resolutions limits the analysis of frame time consistency, but the available Medium data suggests stable performance.

Low settings average 159 FPS, Medium settings average 139 FPS with min and max of 118 and 160 FPS, High settings average 117 FPS, and Ultra settings average 96 FPS. The 4K Medium data shows a min-to-max spread of 42 FPS, which is tighter than the 1440p spread, suggesting that the GPU’s workload is more consistent at higher resolutions where frame times are longer.

The absence of min and max FPS data for Low, High, and Ultra settings limits the analysis of frame time consistency for those configurations. However, the available Medium settings data across all three resolutions shows that the system maintains smooth performance without severe dips. The 4K Ultra average of 96 FPS indicates that even the most demanding settings leave headroom for refresh rates above 60 Hz, making this combo suitable for high-refresh 4K displays.

Settings Recommendations

The measured FPS data allows for concrete settings recommendations based on target refresh rates and resolutions. For 1080p displays with 240 Hz or higher refresh rates, Ultra settings at 273 FPS exceed the display’s capability, so High settings at 334 FPS provide a comfortable margin. For 1440p displays with 144 Hz refresh rates, High settings at 216 FPS exceed the target, while Ultra at 177 FPS also remains above 144 FPS, allowing players to choose between maximum visual quality and higher frame headroom.

For 4K displays with 120 Hz refresh rates, High settings at 117 FPS nearly saturate the display, while Ultra at 96 FPS leaves room for refresh rate synchronization. The data suggests that 4K Ultra is the best experience for players prioritizing visual fidelity, as the 96 FPS average is well above the 60 FPS minimum for smooth gameplay. For 4K displays with 144 Hz refresh rates, Medium settings at 139 FPS get closer to the target, though High at 117 FPS is a reasonable compromise.

The Medium settings provide the most balanced experience across all resolutions, with 396 FPS at 1080p, 256 FPS at 1440p, and 139 FPS at 4K. The min FPS data for Medium settings shows the lowest dips: 336 FPS at 1080p, 218 FPS at 1440p, and 118 FPS at 4K. These minimums are all above 60 FPS, ensuring smooth gameplay even during intense action sequences. Players seeking the highest visual quality should select Ultra settings, which deliver 273 FPS at 1080p, 177 FPS at 1440p, and 96 FPS at 4K, all of which exceed the 60 FPS threshold for playability.
