Doom

The AMD Ryzen 9 5900X paired with the NVIDIA GeForce RTX 3060 Ti delivers a highly playable Doom experience across all tested resolutions, though the data reveals a clear transition from CPU-bound performance at 1080p to GPU-bound performance at 4K. This combination ranks in the 72nd percentile of all tested combos in this title, indicating solid, above-average performance that scales predictably with settings and resolution.

Resolution Scaling

The measured FPS data shows a classic resolution scaling curve. At 1920x1080 with Low settings, the combo achieves 193 FPS, which drops to 140.5 FPS at High and 117.9 FPS at Ultra. This 75.1 FPS gap between Low and Ultra at 1080p suggests that even at this resolution, the GPU is being taxed by the higher graphical presets, but the CPU is still capable of feeding it enough data. Moving to 2560x1440, the same pattern holds: Low produces 125.4 FPS, High drops to 89.1 FPS, and Ultra falls to 74.4 FPS. The percentage drop from 1080p Low to 1440p Low is 35%, while the drop from 1080p High to 1440p High is 36.6%, indicating consistent scaling behavior.

The bottleneck becomes more apparent at 3840x2160. Here, the average FPS collapses to 47.5 FPS at High and just 38.1 FPS at Ultra. Even at Low settings, 4K yields only 64.5 FPS, which is a 66.6% reduction compared to the 1080p Low result. This significant drop suggests that the RTX 3060 Ti is the primary limiting component at 4K, as the pixel throughput demand outstrips what the GPU can deliver. The fact that the 1080p to 1440p scaling is relatively linear, but the 1440p to 4K scaling is much steeper, reinforces that the GPU's memory bandwidth of 448.0 GB/s and its 8 GB GDDR6 frame buffer are being saturated at the higher resolution.

How This Combo Ranks

In the benchmark database, this specific CPU-GPU pairing achieves a combo rank of 1212 out of 1681 tested combinations for Doom. This places it in the 72nd percentile, which is a solid mid-to-upper tier result for a game released in 2016. The ranking suggests that while this combo is not among the elite configurations, it outperforms a substantial majority of other pairings tested in this title.

The CPU itself holds a 90th percentile ranking against all CPUs, with an average benchmark score of 39453. Its nearest rivals in the CPU database include the AMD EPYC 4245P (score 39383, delta 0.2%), the AMD Ryzen 7 PRO 8845HS (score 39747, delta -0.7%), the Intel Core i7-13700F (score 39095, delta 0.9%), and the Intel Core i7-13700 (score 39857, delta -1%). These deltas show that the 5900X is effectively performance-equivalent to these other high-end processors, with all differences within a 1% band.

On the GPU side, the RTX 3060 Ti ranks in the 69th percentile against all GPUs, with an average benchmark score of 25120. Its nearest rivals are the AMD Radeon RX 6700M (score 25180, delta -0.2%), the AMD Radeon RX 6600 (score 25235, delta -0.5%), the AMD Radeon 890M (score 25246, delta -0.5%), and the AMD Radeon RX 580 2048SP (score 25287, delta -0.7%). These very tight deltas indicate that the RTX 3060 Ti sits at the center of a dense cluster of similarly-performing GPUs, with no single rival having a decisive advantage in synthetic benchmarks.

FAQ

Q: What is the maximum average FPS achievable with this combo in Doom?

A: The highest recorded average FPS is 193, achieved at 1920x1080 with Low settings. At Ultra settings, the maximum average FPS drops to 117.9 at the same resolution.

Q: How does the combo perform at 4K Ultra settings?

A: At 3840x2160 with Ultra settings, the average FPS is 38.1, which is below the 60 FPS threshold commonly considered smooth for FPS titles. The Low setting at 4K yields a more playable 64.5 FPS.

Q: Is the CPU or GPU the limiting factor at 1080p?

A: The data shows a 75.1 FPS difference between Low and Ultra at 1080p, indicating the GPU is still heavily taxed by higher settings. However, the CPU's high single-thread performance (3DMark single-thread score of 941) suggests it is not the primary bottleneck at this resolution.

Q: What is the combo's rank among all tested configurations for Doom?

A: The combination ranks 1212 out of 1681 tested combos, placing it in the 72nd percentile. This means it outperforms roughly 72% of all other CPU-GPU pairings tested in this game.

Q: How does the RTX 3060 Ti compare to its closest performance rivals?

A: The RTX 3060 Ti's average benchmark score of 25120 is within 0.7% of its nearest rivals, including the AMD Radeon RX 6600 (25235) and the AMD Radeon 890M (25246). This indicates near-identical synthetic performance among these GPUs.

Q: Does the game support high refresh rate monitors with this setup?

A: At 1080p with High settings, the combo reaches 140.5 FPS, which exceeds the 120 Hz refresh rate common on many gaming monitors. At 1440p High, the 89.1 FPS result is suitable for 60-75 Hz displays but not for 144 Hz panels.

Measured FPS Breakdown

The complete measured FPS dataset for this combo in Doom is as follows:

At 1920x1080, the Low preset produces an average of 193 FPS. The Medium preset yields 166.8 FPS, representing a 13.6% reduction from Low. High settings deliver 140.5 FPS, a 27.2% reduction from Low. The Ultra preset produces 117.9 FPS, which is a 38.9% reduction from the Low result. This progression shows that each step in settings quality incurs a significant but manageable performance cost at this resolution.

At 2560x1440, the Low preset averages 125.4 FPS. Medium settings drop to 110.3 FPS, a 12% reduction. High settings yield 89.1 FPS, a 29% reduction from Low. The Ultra preset produces 74.4 FPS, which is a 40.7% reduction from Low. The percentage drops from Low to Ultra are similar across 1080p and 1440p, suggesting the GPU is handling the additional pixel count proportionally.

At 3840x2160, the Low preset averages 64.5 FPS. Medium settings produce 62.1 FPS, a minimal 3.7% reduction. High settings yield 47.5 FPS, a 26.4% reduction from Low. The Ultra preset produces 38.1 FPS, a 40.9% reduction from Low. The very small gap between Low and Medium at 4K (only 2.4 FPS) indicates that the GPU is becoming so pixel-bound that the difference in rendering complexity between these two presets has little impact on frame rate.

CPU Role

The AMD Ryzen 9 5900X is a 12-core, 24-thread processor based on the Zen 3 architecture (codenamed Vermeer), manufactured on a 7 nm process by TSMC. It features a base clock of 3.70 GHz and a boost clock of 4.80 GHz, with a 64 MB L3 cache. The processor's synthetic benchmark scores are strong: it achieves a Cinebench R23 multi-core score of 33150 and a single-core score of 4680. In 3DMark, the 16-thread score is 9075, while the single-thread score is 941.

For Doom, which is an FPS title that relies heavily on single-thread performance for game logic and draw calls, the 5900X's single-core capabilities are particularly relevant. The 3DMark single-thread score of 941 and the Cinebench R23 single-core score of 4680 indicate that the processor can handle the game's main thread without becoming a bottleneck at lower resolutions. This is evidenced by the 1080p Low result of 193 FPS, which is likely close to the game engine's maximum frame rate ceiling given the CPU's performance.

The processor's multi-threaded performance, while not critical for this specific game, ensures headroom for background tasks and streaming. The 12 cores and 24 threads deliver a PassMark multi-thread score of 39002, which places it in the 90th percentile of all CPUs. The nearest rivals, such as the Intel Core i7-13700 with an average score of 39857, show that the 5900X is competitive with newer generation processors, though the i7-13700 holds a 1% lead in average benchmark score.

The CPU's 105 W TDP and dual-channel DDR4 memory support with 51.2 GB/s bandwidth are adequate for feeding the RTX 3060 Ti. The PCIe Gen 4 interface provides sufficient bandwidth for the GPU's PCIe 4.0 x16 bus connection. In this configuration, the data indicates that the CPU is not the limiting factor at any resolution tested, as the FPS scaling from 1080p to 1440p and 4K follows a pattern consistent with GPU-bound performance, particularly at 4K where the RTX 3060 Ti's 8 GB GDDR6 memory and 448.0 GB/s bandwidth become the primary constraints.
