Doom

The AMD Ryzen 5 5600 paired with the NVIDIA GeForce RTX 3080 Ti delivers exceptional performance in Doom, with the data showing that the GPU becomes the primary limiting factor only at 4K Ultra settings. At 1080p and 1440p, this combination produces frame rates well above the threshold for high-refresh-rate gaming, with the 312 FPS average at 1080p Low being the standout result. The combination ranks in the 74th percentile among all tested CPU/GPU combos for this game, placing it at rank 963 out of 3712 total combinations, which indicates a strong but not top-tier pairing for this title.

Resolution Scaling

The measured FPS data reveals a clear and predictable scaling pattern as resolution increases from 1080p to 4K. At High settings, the average frame rate drops from 230 FPS at 1920x1080 to 149 FPS at 2560x1440, then further to 81 FPS at 3840x2160. This represents a 35% reduction when moving from 1080p to 1440p, and another 46% reduction when moving from 1440p to 4K. The scaling pattern suggests that the RTX 3080 Ti remains the dominant performance driver throughout, with the Ryzen 5 5600 providing sufficient headroom even at the lowest resolution.

The Low settings data reinforces this interpretation, showing 312 FPS at 1080p, 202 FPS at 1440p, and 109 FPS at 4K. The fact that 1080p Low produces over 300 FPS indicates that the CPU is not bottlenecking the system, as even a modest six-core processor like the Ryzen 5 5600 can feed the GPU enough frames at this resolution. The RTX 3080 Ti's 12 GB of GDDR6X memory and 912.4 GB/s bandwidth appear more than adequate for this game, as even at 4K Ultra the average FPS remains playable at 66.

The gap between Low and Ultra settings widens at higher resolutions in absolute terms but narrows proportionally. At 1080p, the difference between Low and Ultra is 124 FPS (312 versus 188), while at 4K the difference shrinks to 43 FPS (109 versus 66). This pattern indicates that the GPU's shading units and memory bandwidth become increasingly taxed as resolution increases, making the 34.10 TFLOPS FP32 compute capability of the RTX 3080 Ti the limiting factor at 4K rather than the 6-core, 12-thread CPU.

CPU Role

The Ryzen 5 5600 brings 6 cores and 12 threads based on the Zen 3 architecture, with a base clock of 3.50 GHz and a boost clock of 4.40 GHz. For Doom, a game released in 2016, this processor provides ample computational headroom. The benchmark results show the CPU's single-thread performance is strong, with a Cinebench R23 single-core score of 2584 and a Geekbench single-core score of 1936, which are relevant because Doom's engine typically relies on a few heavily utilized threads for game logic and draw call submission.

The multi-threaded capabilities of the Ryzen 5 5600, evidenced by a Cinebench R23 multi-core score of 18309 and a Passmark multithread score of 21541, are more than sufficient for this title. The data shows that even at 1080p Low settings, where the CPU would be most likely to become a bottleneck, the combination still achieves 312 FPS average. This suggests that the processor's 32 MB of shared L3 cache helps maintain low latency memory access patterns that benefit game performance.

The processor's 65 W TDP and 7 nm process node contribute to its efficiency, but more importantly for gaming, the architecture's IPC improvements from Zen 3 allow it to keep pace with the RTX 3080 Ti's frame output. The 3DMark single-thread score of 882 and 2-thread score of 1737 indicate that the CPU can handle the dual-threaded workloads common in game engines without becoming a limiting factor. At 4K Ultra settings where the average FPS drops to 66, the CPU is clearly not the constraint; the GPU is operating at its performance ceiling.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the dominant component in this pairing, featuring 10240 shading units, 320 TMUs, and 112 ROPs based on the Ampere architecture. The GPU's 12 GB of GDDR6X memory on a 384-bit bus provides 912.4 GB/s of bandwidth, which proves crucial for Doom's texture streaming at higher resolutions. The benchmark data shows the GPU's DirectX 12 performance with a Passmark DirectX 12 score of 110 and DirectX 11 score of 223, indicating strong API-level optimization for this title.

The GPU's clock speeds of 1365 MHz base and 1665 MHz boost, combined with its 34.10 TFLOPS FP32 compute, deliver the raw throughput needed for Doom's demanding rendering techniques. The measured FPS data shows the GPU scaling from 312 FPS at 1080p Low to 66 FPS at 4K Ultra, a 79% reduction in performance as resolution increases. This scaling is consistent with a GPU-bound scenario at all tested configurations, as the CPU provides enough headroom to avoid constraining the GPU.

The RTX 3080 Ti's 350 W TDP and 750 W suggested PSU requirement indicate its power-hungry nature, but the performance payoff is clear in the frame rates achieved. The GPU's 80 RT cores and 320 tensor cores suggest future-proofing for games with ray tracing, though Doom from 2016 does not utilize these features. The 3DMark Steel Nomad DX12 score of 5077 and Geekbench Vulkan score of 192697 demonstrate the GPU's modern API performance, which aligns with Doom's Vulkan support and explains the high frame rates observed.

How This Combo Ranks

This specific combination of AMD Ryzen 5 5600 and NVIDIA GeForce RTX 3080 Ti ranks 963 out of 3712 tested combinations for Doom, placing it in the 74th percentile of all systems tested. This ranking indicates that while the pairing delivers strong performance, there are many combinations that achieve higher frame rates in this title. The rank reflects a balanced system where the GPU's high-end positioning (83rd percentile among GPUs) is somewhat offset by the CPU's mid-range positioning (74th percentile among CPUs).

The 963rd rank out of 3712 combinations means approximately 26% of tested systems outperform this pairing in Doom. Given that the RTX 3080 Ti is a high-end GPU from the Ampere generation, the ranking suggests that Doom's engine benefits from even stronger CPUs or that some combinations with slightly slower GPUs but faster CPUs achieve better results. The data shows that at lower resolutions like 1080p, a faster CPU could potentially push frame rates even higher than the 312 FPS ceiling observed.

However, the combination's performance is far from disappointing. The 74th percentile ranking among all combos places it in the upper quartile, and the measured FPS figures show that this system can handle Doom at maximum settings across all resolutions with playable frame rates. The 4K Ultra performance of 66 FPS average is particularly notable, as it demonstrates the RTX 3080 Ti's capability to run modern titles at 4K with high settings while maintaining smooth gameplay.

Measured FPS Breakdown

The complete measured FPS data for this combination across all resolutions and settings is as follows:

At 1920x1080 resolution, the average FPS ranges from 188 at Ultra settings to 312 at Low settings. The High setting averages 230 FPS, while Medium averages 272 FPS with a minimum of 231 FPS and maximum of 313 FPS. All 1080p configurations deliver well above 144 Hz refresh rates, making this resolution ideal for competitive play.

At 2560x1440 resolution, the average FPS ranges from 122 at Ultra settings to 202 at Low settings. High settings average 149 FPS, and Medium averages 176 FPS with a minimum of 150 FPS and maximum of 202 FPS.
