A: The RTX 5090 D features 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth. Memory clocks run at 1750 MHz base with 28 Gbps effective speed. This large memory pool and high bandwidth are crucial for high-resolution gaming.

GPU Role

The NVIDIA GeForce RTX 5090 D is built on the Blackwell 2.0 architecture using TSMC's 5 nm process, packing 92,200 million transistors into a 750 mm² die. The GPU operates at a base clock of 2017 MHz and boosts to 2407 MHz, with memory running at 1750 MHz (28 Gbps effective). These specifications translate into a pixel rate of 423.6 GPixel/s and a texture rate of 1,636.8 GTexel/s, which are directly relevant to how quickly the card can fill frames in a fast-paced FPS like Doom.

The 32 GB GDDR7 memory pool with 512-bit bus width and 1.79 TB/s bandwidth ensures that even at 4K resolution with high-detail textures, the GPU never starves for data. In Doom, which is known for its rapid movement and dense environments, this memory bandwidth allows the card to maintain high frame rates without texture pop-in or stutter. The 21760 shading units and 176 ROPs provide ample raw compute for the game's Vulkan-based rendering engine.

The GPU's FP32 performance of 104.8 TFLOPS means that compute-heavy effects like dynamic lighting and particle systems are handled with headroom. The 170 RT cores and 680 tensor cores, while not heavily utilized in this 2016 title, indicate that the card is future-proofed for more demanding games. The 575 W TDP and dual-slot design with a single 16-pin power connector suggest that this is a flagship-class card, and its performance in Doom reflects that positioning.

The measured FPS data shows that the GPU is the primary driver of performance scaling across settings. At 1080p Low, the combo hits 388 FPS, but at 4K Ultra it drops to 102 FPS. This 286 FPS spread across the resolution and settings matrix is characteristic of a GPU-bound scenario, where the RTX 5090 D's capabilities are being fully exercised at higher resolutions and quality presets.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a clear pattern of GPU dominance in Doom. At 1920x1080 with Low settings, the combo produces 388 FPS. Moving to 2560x1440 at the same settings drops this to 314 FPS, a 19% reduction. At 3840x2160 Low, the frame rate falls to 170 FPS, which is a 46% drop from the 1080p figure. This scaling indicates that the RTX 5090 D is the limiting factor at higher resolutions, as the CPU has ample headroom to feed frames.

The Medium settings preset shows a similar trend: 370 FPS at 1080p, 273 FPS at 1440p, and 148 FPS at 4K. The percentage drops between resolutions are 26% and 46% respectively. For High settings, the progression is 349 FPS at 1080p, 231 FPS at 1440p (34% drop), and 125 FPS at 4K (46% drop from 1440p). Ultra settings follow the same pattern: 292 FPS at 1080p, 189 FPS at 1440p (35% drop), and 102 FPS at 4K (46% drop from 1440p).

The consistent 46% reduction from 1440p to 4K across all settings presets strongly suggests that the GPU's rendering workload scales linearly with pixel count. The RTX 5090 D's 1.79 TB/s memory bandwidth is being fully utilized at 4K, and the 32 GB frame buffer allows for high-resolution textures without compromise. The CPU, with its 10 cores and 16 threads boosting to 4.70 GHz, is not the bottleneck in any configuration tested.

The min FPS values for Medium settings provide additional insight into frame time consistency. At 4K Medium, the minimum is 126 FPS against an average of 148 FPS, which is an 85% ratio. At 1440p Medium, the minimum is 232 FPS against 273 FPS average (85% ratio). At 1080p Medium, the minimum is 314 FPS against 370 FPS average (also 85% ratio). This consistent 85% minimum-to-average ratio indicates stable frame pacing across all resolutions.

Its 83rd percentile among all CPUs indicates strong overall performance, though it is not a top-tier halo part. The nearest rivals, including the AMD Ryzen 7 PRO 8840U and Intel Core i9-11900, are within 0.5% of its average score, suggesting that the CPU is not the differentiator in this combo's ranking.

The GPU's 92nd percentile ranking among all GPUs, with an average benchmark score of 77,712, is the primary driver of the combo's 37th place finish. The RTX 5090 D's nearest rivals in the GPU benchmark database are mobile and datacenter parts, which highlights its position in the desktop GPU hierarchy. The 1.1% lead over the AMD Radeon RX 6650M XT and the 1.6% deficit to the RX 6850M XT show that the 5090 D is competitive with the fastest GPUs available.

In the context of Doom specifically, the measured FPS data shows that this combo can push well beyond the refresh rate of typical high-end monitors. Even at 4K Ultra, the 102 FPS average is above the 60 FPS standard, while at 1440p High, the 231 FPS average exceeds the capabilities of most 240 Hz displays. The 37th rank out of 2,930 combos indicates that only a small number of configurations can outperform this pairing in Doom.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. Low settings produce 388 FPS average, Medium reaches 370 FPS with a minimum of 314 FPS and maximum of 425 FPS, High achieves 349 FPS, and Ultra drops to 292 FPS. The spread from Low to Ultra is 96 FPS, representing a 25% performance penalty for the highest quality preset at this resolution.

Moving to 2560x1440, the frame rates remain very high but show the expected decline. Low settings yield 314 FPS, Medium averages 273 FPS with a minimum of 232 FPS and maximum of 314 FPS, High produces 231 FPS, and Ultra falls to 189 FPS. The difference between Low and Ultra at 1440p is 125 FPS, a 40% penalty. This larger percentage gap compared to 1080p indicates that the GPU is working harder at this resolution.

At 3840x2160, the performance is still strong but the frame rates drop significantly. Low settings average 170 FPS, Medium reaches 148 FPS with a minimum of 126 FPS and maximum of 170 FPS, High produces 125 FPS, and Ultra falls to 102 FPS. The Low to Ultra spread is 68 FPS, a 40% penalty, which is consistent with the 1440p scaling.

The Medium settings preset is the only one with complete min/max data at all three resolutions. The maximum FPS values at Medium are 425 at 1080p, 314 at 1440p, and 170 at 4K. These maximums align closely with the Low settings averages at each resolution, suggesting that Medium settings occasionally allow frame rates to spike to Low-level performance. The minimum FPS values of 314, 232, and 126 at 1080p, 1440p, and 4K respectively show that even the lowest dips remain playable.

Settings Recommendations

For 1920x1080 displays, the Ultra preset at 292 FPS average is the recommended choice. This frame rate exceeds the refresh rate of virtually all monitors on the market, including 240 Hz and 360 Hz panels. The 96 FPS difference between Ultra and Low at this resolution is negligible when both are above 290 FPS, so maximizing visual quality is the optimal trade-off.

At 2560x1440, the High preset at 231 FPS provides the best balance. While Low settings reach 314 FPS and Ultra drops to 189 FPS, High's 231 FPS comfortably exceeds 144 Hz and 165 Hz refresh rates while delivering superior visual fidelity. For users with 240 Hz 1440p monitors, the Medium preset at 273 FPS is worth considering, though the visual difference between Medium and High may justify the 42 FPS reduction.

For 3840x2160, the High preset at 125 FPS is recommended for most users. This frame rate exceeds the 120 Hz refresh rate found on many 4K displays and provides excellent visual quality. The Ultra preset at 102 FPS is viable for 60 Hz displays or for users who prioritize image quality over frame rate, but the 23 FPS penalty from High to Ultra is significant. The Medium preset at 148 FPS is the choice for 144 Hz 4K monitors, offering a 23 FPS advantage over High while sacrificing some visual fidelity.

The data shows that Doom is highly optimized, as evidenced by the 388 FPS maximum at 1080p Low. This optimization means that even the Ultra preset at 4K, which produces 102 FPS, remains playable on standard 60 Hz displays. The consistent 85% minimum-to-average ratio across all Medium presets indicates stable frame pacing, which is critical for a fast-paced FPS where frame time consistency matters as much as average frame rate.

The recommended settings prioritize frame rate headroom above the display's refresh rate. For 1080p, Ultra is the clear choice. For 1440p, High offers the best compromise. For 4K, High is recommended for 120 Hz displays, with Medium as an alternative for 144 Hz panels. The RTX 5090 D's 32 GB memory ensures that texture quality at Ultra settings does not cause stuttering or loading issues, but the frame rate data shows that the GPU's compute resources are the limiting factor at higher resolutions.
