Doom

The AMD Ryzen 7 5700X3D and NVIDIA GeForce RTX 3080 Ti combination delivers exceptional performance in Doom, placing the system in the 460th position out of 1681 tested combos. This pairing produces frame rates that range from playable at maximum settings in 4K to extraordinarily high refresh rate territory at 1080p, making it a formidable choice for this classic FPS.

Resolution Scaling

The data shows a clear and predictable pattern of performance degradation as resolution increases, though the magnitude of the drop reveals important insights about where the bottleneck lies. At 1080p with High settings, the system produces 228.9 FPS, which falls to 149.2 FPS at 1440p and further to 81.7 FPS at 4K. This represents a 35% reduction moving from 1080p to 1440p and an additional 45% reduction moving from 1440p to 4K.

The scaling pattern across all settings presets tells a consistent story. With Ultra settings, the system achieves 190.7 FPS at 1080p, 121.5 FPS at 1440p, and 66.1 FPS at 4K. The 4K Ultra result is particularly telling—it represents only 34.7% of the 1080p Ultra performance, indicating that the GPU is being pushed to its absolute limits at this resolution and quality combination. The RTX 3080 Ti's 12 GB of GDDR6X memory and 912.4 GB/s bandwidth are clearly being saturated at 4K, especially with Ultra settings that demand the most from the memory subsystem.

Conversely, the 1080p results across all settings presets suggest that the CPU is becoming the limiting factor at lower resolutions. The Ryzen 7 5700X3D's 8 cores and 16 threads, with a boost clock of 4.10 GHz, are sufficient to feed the GPU at 1080p, but the frame rates plateau in the 190-308 FPS range rather than scaling infinitely with graphics settings reductions. This indicates that while the GPU has headroom at 1080p, the CPU's Zen 3 architecture and 96 MB of shared L3 cache are doing the heavy lifting to maintain these high frame rates.

CPU Role

The Ryzen 7 5700X3D is a Zen 3 Vermeer part built on TSMC's 7 nm process, featuring 8 cores and 16 threads with a base clock of 3.00 GHz and a boost clock of 4.10 GHz. Its 96 MB of shared L3 cache is the standout feature for gaming workloads, providing substantial capacity for the engine's data-intensive tasks. The CPU's benchmark scores reinforce its gaming pedigree: the Cinebench R23 multicore score of 22366 and single-core score of 3157 show strong multi-threaded capability, while the 3DMark 16-thread score of 6764 and max-thread score of 6755 demonstrate consistent scaling across all cores.

In Doom, the CPU's role becomes increasingly critical as resolution decreases. At 1080p Low settings, the system reaches 308.7 FPS, which is the highest measured result in the entire dataset. This figure suggests that the CPU is capable of sustaining extremely high frame rates when the GPU is not the primary constraint. The 0.2% performance delta compared to the Intel Core i7-1360P and 0.3% delta versus the AMD Ryzen 5 7600X3D in average benchmark scores places this chip in a tight competitive cluster, but the 3D V-Cache technology appears to provide an edge in this game's specific workload characteristics.

The 105 W TDP and DDR4 memory support with dual-channel configuration and 51.2 GB/s bandwidth represent a mature platform that pairs well with the RTX 3080 Ti. The CPU's 82nd percentile ranking among all CPUs, combined with its 24673 average benchmark score, indicates that it is a top-tier gaming processor that will not hold back the GPU in most scenarios.

How This Combo Ranks

The combination's 460th place ranking out of 1681 tested combos places it in the top 27% of all systems tested. This is a strong result for a pairing that uses a previous-generation GPU and a mid-range enthusiast CPU from the 5000 series. The ranking reflects the overall balance of the system—neither component is a weak link, and both are operating well within their performance envelopes.

The RTX 3080 Ti's average benchmark score of 41224 and 83rd percentile ranking among all GPUs positions it slightly below the RTX 3090 (delta of -0.5%) and RTX 5070 (delta of -1.1%), but these differences are marginal. The GPU's PassMark G3D score of 26896 and Geekbench Vulkan score of 171798 demonstrate its raw compute capabilities, while the 3DMark Steel Nomad DX12 score of 5077 provides a modern API performance data point.

This ranking suggests that the system is well-matched for Doom, where the engine's optimization and the hardware's capabilities combine to produce excellent results. The 460th position out of 1681 indicates that while there are many faster systems, this configuration sits comfortably in the upper tier of performance, particularly for a game that is not the most demanding modern title.

Measured FPS Breakdown

At 1080p, the system delivers exceptional performance across all settings presets. Low settings produce 308.7 FPS, Medium produces 272.6 FPS, High produces 228.9 FPS, and Ultra produces 190.7 FPS. The spread between Low and Ultra is 118 FPS, representing a 38% performance difference. This is a substantial gap, but even the Ultra result is high enough to drive a 144 Hz or 165 Hz monitor without issue.

The 1440p results show a more pronounced impact from graphics settings. Low settings achieve 205.9 FPS, Medium achieves 178.1 FPS, High achieves 149.2 FPS, and Ultra achieves 121.5 FPS. The 84.4 FPS difference between Low and Ultra represents a 41% drop, indicating that the GPU's workload is increasing more significantly at this resolution. The Ultra result of 121.5 FPS is still excellent for 1440p gaming, comfortably exceeding the 100 FPS threshold that many gamers consider the sweet spot for competitive play.

At 4K, the system's performance drops considerably but remains playable. Low settings produce 109.2 FPS, Medium produces 94.5 FPS, High produces 81.7 FPS, and Ultra produces 66.1 FPS. The 43.1 FPS difference between Low and Ultra represents a 40% drop, consistent with the scaling observed at 1440p. The Ultra result of 66.1 FPS is above the 60 FPS minimum for acceptable 4K gaming, though it leaves little headroom for demanding scenes or future engine updates.

GPU Role

The RTX 3080 Ti is an Ampere architecture GPU built on Samsung's 8 nm process, featuring 10240 shading units, 320 TMUs, and 112 ROPs. Its 12 GB of GDDR6X memory operates at 19 Gbps effective across a 384-bit bus, delivering 912.4 GB/s of bandwidth. The GPU's boost clock of 1665 MHz and base clock of 1365 MHz, combined with 80 RT cores and 320 Tensor cores, make it a capable performer for both rasterization and ray-accelerated workloads.

In Doom, the GPU's role is most evident at 4K resolution, where the frame rates scale more dramatically with settings changes. The jump from Ultra (66.1 FPS) to High (81.7 FPS) represents a 23.6% improvement, while the jump from High to Medium (94.5 FPS) adds another 15.7%. This pattern indicates that the Ultra preset's additional features—likely including higher quality shadows, reflections, and post-processing effects—are particularly demanding on the GPU's compute and memory resources.

The GPU's PassMark G3D score of 26896 and Geekbench OpenCL score of 191309 place it in the upper echelon of graphics cards, with its 83rd percentile ranking confirming its position. The 34.10 TFLOPS of FP32 performance and 532.8 GTexel/s texture rate provide substantial raw throughput, while the 186.5 GPixel/s pixel rate ensures efficient fill rate for high-resolution rendering. The 350 W TDP and suggested 750 W PSU requirement indicate that this is a power-hungry component, but the performance it delivers justifies the electrical demands.

Settings Recommendations

For 1080p gaming, the Ultra preset at 190.7 FPS is the clear recommendation. This setting delivers the highest visual quality while still maintaining frame rates well above what any current display can refresh. Even the most demanding 360 Hz monitors would be nearly saturated by this performance level, making Ultra the obvious choice for competitive or casual play at this resolution.

At 1440p, the High preset at 149.2 FPS offers the best balance between visual fidelity and performance. The Medium preset at 178.1 FPS provides a noticeable 19.4% performance boost over High, but the visual quality difference between these two presets is typically more significant than the frame rate gap suggests. The Ultra preset at 121.5 FPS is also viable, particularly for gamers who prioritize image quality over maximum refresh rates, but High provides the best overall experience for most users.

For 4K gaming, the High preset at 81.7 FPS is the recommended choice. The Medium preset at 94.5 FPS provides a 15.7% performance improvement but sacrifices notable visual quality in a resolution where detail is already abundant. The Ultra preset at 66.1 FPS is borderline playable but risks dipping below 60 FPS in demanding scenes, which can be jarring for fast-paced action. The Low preset at 109.2 FPS is unnecessary, as the visual degradation at 4K would be immediately apparent and the performance gain over High is not worth the quality loss.

The data indicates that this system's sweet spot is 1440p High, where it delivers 149.2 FPS with excellent visual quality and substantial headroom. For users with 4K displays, High settings provide the best compromise, while 1080p users can confidently max out all settings without concern.
