Doom

# How This Combo Ranks

The pairing of the AMD Ryzen 5 5600GT with the NVIDIA GeForce RTX 5090 D lands at rank 90 out of 2,930 tested combos in Doom. That places it in the 97th percentile of all configurations evaluated, a position that reflects the unusual balance between a mid-range 2024 CPU and a flagship 2025 GPU. The data shows this combo outperforms the overwhelming majority of systems, but the ranking also raises questions about how much headroom the processor leaves on the table when paired with such a powerful graphics card.

Looking at the individual components, the RTX 5090 D sits at the 92nd percentile among all GPUs, while the Ryzen 5 5600GT reaches only the 74th percentile among all CPUs. The gap suggests the CPU is the limiting factor in this pairing, yet the overall combo still cracks the top 3% of tested systems. In Doom, a game that scales well across hardware, this combination produces frame rates that would satisfy most enthusiasts, though the CPU's relative weakness compared to the GPU becomes apparent in lower-resolution scenarios where the processor must feed frames faster.

The measured data confirms this dynamic. At 1080p, the combo achieves 350 FPS on Low settings, but at 4K Ultra it drops to 102 FPS. The spread between the CPU's best and worst case scenarios in this game is substantial, and the ranking reflects that the combo excels in GPU-bound situations while showing its limits in CPU-bound ones. Still, being 90th out of 2,930 is a strong showing for a processor that was not designed to pair with a 32 GB GDDR7 graphics card.

# GPU Role

The NVIDIA GeForce RTX 5090 D is the dominant component in this pairing, and its specifications explain why. The GPU carries 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth. That memory configuration is overkill for Doom, a 2016 title, but it ensures the GPU never bottlenecks on memory capacity or bandwidth at any resolution. The base clock runs at 2017 MHz with a boost clock of 2407 MHz, and the memory operates at an effective 28 Gbps. These clocks, combined with 21,760 shading units, 680 texture mapping units, and 176 raster output units, give the card a theoretical peak of 104.8 TFLOPS of FP32 compute.

In Doom, the GPU's role becomes more pronounced as resolution increases. At 4K High, the combo delivers 125 FPS, while at 1080p High it hits 315 FPS. The GPU's massive compute resources are the reason the combo maintains playable frame rates even at 4K Ultra, where it still produces 102 FPS. The card's 170 ray tracing cores and 680 tensor cores are largely irrelevant for this game, which does not use those features, but the raw rasterization power is what drives the high frame rates.

The RTX 5090 D's benchmark scores reflect its dominance. Its PassMark G3D score of 44,065 and 3DMark Steel Nomad DX12 score of 14,326 place it at the 92nd percentile among all GPUs. Its nearest rivals in the benchmark database — the AMD Radeon RX 6650M XT, RX 6850M XT, and NVIDIA Tesla P100 variants — are all within 2.4% of its average score, which is surprising given the generational gap. The data suggests that while the RTX 5090 D is a top-tier card, its raw compute benchmarks are not as far ahead of the competition as its specs might imply. In Doom specifically, the GPU's ability to push high frame rates at 4K is the key takeaway, and the measured FPS shows it delivers.

# CPU Role

The AMD Ryzen 5 5600GT is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Cezanne. It operates on the AM4 socket with a base clock of 3.60 GHz and a boost clock of 4.60 GHz. The CPU has 16 MB of L3 cache, 512 KB of L2 per core, and 64 KB of L1 per core, with a 65 W TDP. Its integrated Radeon Vega 7 graphics are present but unused in this discrete GPU configuration. The processor supports DDR4 memory in dual-channel mode with a theoretical bandwidth of 51.2 GB/s, and it connects via PCIe Gen 3 with 16 lanes.

In Doom, the CPU's role is most evident at lower resolutions. At 1080p Low, the combo achieves 350 FPS, but at 1080p Ultra it drops to 292 FPS. That 58 FPS gap suggests the CPU is struggling to feed the GPU at higher settings, even though the GPU has enormous headroom. The CPU's benchmark scores — Cinebench R23 multicore of 17,272 and single-core of 2,438, plus Geekbench multicore of 7,986 and single-core of 1,843 — place it at the 74th percentile among all CPUs. Its nearest rival, the Intel Core i5-12490F, scores 20,802 on average, which is 0.3% higher, indicating the 5600GT is competitive with that chip.

The CPU's 3DMark scores tell a similar story. It achieves 5,523 in the 16-thread test and 913 in the single-thread test. These numbers are respectable for a mid-range processor, but they pale in comparison to the GPU's compute capabilities. In Doom, which can scale to multiple threads, the 6-core, 12-thread configuration is sufficient, but the CPU's PCIe Gen 3 interface and DDR4 memory support could be limiting factors when paired with a PCIe 5.0 GPU. The measured FPS data suggests the CPU becomes a bottleneck at 1080p, where the GPU is waiting for the processor to deliver draw calls and physics calculations.

# Measured FPS Breakdown

The measured FPS data covers three resolutions — 1920x1080, 2560x1440, and 3840x2160 — each with four settings presets: Low, Medium, High, and Ultra. The full breakdown is as follows:

At 1920x1080, the combo delivers its highest frame rates. Low settings produce an average of 350 FPS, Medium reaches 334 FPS with a minimum of 284 and maximum of 384, High hits 315 FPS, and Ultra drops to 292 FPS. The spread from Low to Ultra is 58 FPS, or about 17%. The Medium preset shows the most variance, with a 100 FPS range between minimum and maximum, which indicates some scenes are more demanding than others.

At 2560x1440, frame rates remain high but show a steeper drop as settings increase. Low produces 303 FPS, Medium averages 273 FPS with a range of 232 to 314, High hits 231 FPS, and Ultra falls to 189 FPS. The drop from Low to Ultra is 114 FPS, or about 38%. The gap between Medium's minimum of 232 and High's average of 231 suggests that Medium can sometimes dip below High's performance, likely due to scene complexity.

At 3840x2160, the GPU's dominance becomes clear. Low settings average 170 FPS, Medium averages 148 FPS with a range of 126 to 170, High drops to 125 FPS, and Ultra bottoms out at 102 FPS. The drop from Low to Ultra is 68 FPS, or about 40%. The Medium preset at 4K shows a minimum of 126 FPS, which is barely above the High average of 125, indicating that 4K pushes the GPU hard regardless of settings.

The data reveals a pattern: the CPU limits performance at 1080p, while the GPU limits performance at 4K. At 1440p, the balance shifts depending on settings, with Low being CPU-bound and Ultra being GPU-bound. The minimum FPS values, only recorded for Medium presets, show that 1080p Medium can dip to 284 FPS, 1440p Medium to 232 FPS, and 4K Medium to 126 FPS — all still above the 60 FPS threshold for smooth gameplay.

# FAQ

Q: Why does the combo rank 90th out of 2,930 when the GPU is so powerful?

A: The ranking reflects the combination's overall performance across all tested configs. The RTX 5090 D sits at the 92nd GPU percentile, but the Ryzen 5 5600GT only reaches the 74th CPU percentile. In Doom, the CPU becomes a bottleneck at lower resolutions, preventing the combo from achieving higher ranks that a more balanced pairing might reach.

Q: Is the RTX 5090 D overkill for Doom?

A: The data suggests yes. At 1080p Low, the combo hits 350 FPS, and even at 4K Ultra it manages 102 FPS. Doom is a 2016 title that does not use ray tracing or DLSS, so the GPU's 32 GB of GDDR7 memory and 104.8 TFLOPS of compute are far beyond what this game requires. The GPU's capabilities are better suited for modern titles.

Q: How does the Ryzen 5 5600GT compare to its nearest rivals?

A: The CPU's average benchmark score is 20,733, which is 0.3% lower than the Intel Core i5-12490F's 20,802, and 0.4% lower than the Intel Xeon 6325P's 20,821 and the Intel Core Ultra 5 125U's 20,826. The AMD EPYC 7J13 scores 20,845, which is 0.5% higher. These are all within 1% of each other, indicating the 5600GT is competitive with these chips.

Q: What are the best settings for 4K gameplay?

A: At 4K, High settings produce 125 FPS, which is excellent for a 60 Hz display. Ultra drops to 102 FPS, which is still playable but sacrifices frame rate for marginal visual gains. Medium produces 148 FPS with a minimum of 126, making it the best balance of visual quality and performance at 4K.

Q: Does the CPU bottleneck the GPU in Doom?

A: The data indicates yes at lower resolutions. At 1080p, the frame rate difference between Low (350 FPS) and Ultra (292 FPS) is only 58 FPS, suggesting the CPU cannot fully utilize the GPU's power. At 4K, the GPU becomes the limiting factor, as seen by the 68 FPS drop from Low to Ultra, which is a smaller percentage drop than at 1440p.

Q: How does the combo perform at 1440p compared to 4K?

A: At 1440p, the combo delivers 303 FPS on Low and 189 FPS on Ultra, while at 4K it delivers 170 FPS on Low and 102 FPS on Ultra. The drop from 1440p to 4K is about 44% on Low and 46% on Ultra, indicating the GPU is the primary constraint at both resolutions, but the CPU still has some influence at 1440p.

# Settings Recommendations

The measured FPS data provides clear guidance for optimizing the experience in Doom. At 4K, the Medium preset stands out as the best choice. It produces an average of 148 FPS with a minimum of 126 FPS, which is well above the 60 FPS threshold for smooth gameplay. High settings drop to 125 FPS, which is still playable, but Medium offers a 23 FPS improvement over High with only a modest visual quality reduction. Ultra at 102 FPS is the only preset that falls below 120 FPS, making it less desirable for high-refresh-rate displays.

At 1440p, the High preset at 231 FPS is the sweet spot for most users. It delivers excellent frame rates while maintaining visual fidelity. Medium at 273 FPS is faster but shows a minimum of 232 FPS, which can dip below High's average. Ultra at 189 FPS is still smooth, but the 42 FPS drop from High to Ultra is not worth the minor visual gains. For competitive play, Low at 303 FPS maximizes frame rate, but the visual compromise may not be necessary given High's performance.

At 1080p, the situation is reversed. The CPU limits performance, so frame rates are high across all settings. Low at 350 FPS is the maximum, but Ultra at 292 FPS is only 58 FPS slower. Medium at 334 FPS with a minimum of 284 is a good middle ground. For most users, High at 315 FPS offers the best balance of visual quality and performance. The data suggests that at 1080p, the GPU has so much headroom that settings have minimal impact on playability, making Ultra a viable choice for those who prioritize visuals.

Overall, the recommendations depend on resolution. For 4K, Medium is the optimal preset. For 1440p, High is the best balance. For 1080p, High or Ultra both work well, with the choice coming down to personal preference between frame rate and visual fidelity. The measured data consistently shows that the combo maintains playable frame rates even at the highest settings, so users can prioritize visuals without fear of dropping below 100 FPS at any resolution.

# Resolution Scaling

The FPS drop from 1080p to 4K reveals important information about which component limits performance. At Low settings, the combo delivers 350 FPS at 1080p, 303 FPS at 1440p, and 170 FPS at 4K. That is a 51% drop from 1080p to 4K, or about 180 FPS. At Ultra settings, the drop is from 292 FPS at 1080p to 189 FPS at 1440p to 102 FPS at 4K — a 65% drop, or 190 FPS. The absolute FPS loss is similar across settings, but the percentage drop is larger at Ultra, suggesting the GPU is more heavily taxed at higher settings.

The scaling pattern indicates a shift in the bottleneck. At 1080p, the CPU is the limiting factor because the GPU can render frames faster than the processor can feed it. This is evident in the Small FPS difference between Low (350) and Ultra (292) at 1080p — only 58 FPS. At 4K, the GPU becomes the bottleneck, as shown by the 68 FPS difference between Low (170) and Ultra (102), which is a larger percentage drop. The 1440p results sit in between, with a 114 FPS difference between Low and Ultra, indicating a balanced load.

The data shows that the combo is more GPU-bound at higher resolutions. At 4K Medium, the minimum FPS is 126, which is 21% below the average of 148. At 1440p Medium, the minimum of 232 is 15% below the average of 273. At 1080p Medium, the minimum of 284 is 15% below the average of 334. The relative variance is similar, but the absolute values decline with resolution, confirming that the GPU is the primary constraint at 4K.

This scaling behavior has practical implications. Users with 1080p monitors will see diminishing returns from the RTX 5090 D, as the CPU limits performance. Users with 4K monitors will see the GPU's full potential, but the frame rates will still be high enough for most displays. The combo is best suited for 1440p, where both components contribute meaningfully to performance, and the FPS remains above 189 even at Ultra settings. The data suggests that this pairing is most balanced at 1440p, with the CPU and GPU sharing the workload more evenly than at 1080p or 4K.
