Doom

The AMD Ryzen 7 5800X3D paired with the NVIDIA GeForce RTX 3060 Ti delivers a benchmark profile that clearly separates the CPU’s capability from the GPU’s limits in Doom. The measured frame rates across resolutions and settings show a system that is firmly GPU-bound at higher graphical loads, while the processor’s cache-heavy design ensures headroom that keeps even the most demanding 1080p scenarios smooth.

Resolution Scaling

The frame rate drop from 1080p to 4K reveals a classic GPU-bound curve. At 1080p High, the combo produces 138.6 FPS, which falls to 92.3 FPS at 1440p, and further to 52 FPS at 4K. This represents a 33% reduction from 1080p to 1440p, and a 44% reduction from 1440p to 4K. The scaling is not linear, indicating that the RTX 3060 Ti is the limiting factor as pixel count increases.

The gap between Low and Ultra settings widens dramatically at higher resolutions. At 1080p, the spread from Low (191.1 FPS) to Ultra (115.1 FPS) is 76 FPS. At 1440p, that spread narrows to 47.2 FPS (124.1 Low versus 76.9 Ultra). At 4K, the spread is 31.8 FPS (69.9 Low versus 38.1 Ultra). This compression of the settings range as resolution rises confirms that the GPU’s pixel throughput, not the CPU’s instruction rate, is the bottleneck. The Ryzen 7 5800X3D with its 96 MB of shared L3 cache is more than capable of feeding frames at all tested resolutions, so the observed scaling is attributable entirely to the graphics card’s 448.0 GB/s memory bandwidth and 8 GB of GDDR6.

Interesting detail: the 4K Ultra result of 38.1 FPS is less than half the 1080p High result, yet the 1080p Low result of 191.1 FPS shows the GPU can push nearly 200 frames when the load is light. This indicates the RTX 3060 Ti has a wide performance envelope, but its 16.20 TFLOPS of FP32 compute is saturated quickly by Doom’s effects-heavy Ultra preset at 4K.

FAQ

Q: What is the highest average frame rate recorded for this combo in Doom?

A: The highest measured average is 191.1 FPS at 1920x1080 with Low settings. The next best is 168.6 FPS at 1080p Medium, showing a 22.5 FPS penalty for the medium preset.

Q: How does the RTX 3060 Ti compare to its nearest rivals in overall benchmark scores?

A: The GPU’s average benchmark score is 25120, which is 0.2% below the AMD Radeon RX 6700M (25180) and 0.5% below the AMD Radeon RX 6600 (25235). It sits above the AMD Radeon 890M and the AMD Radeon RX 580 2048SP, both trailing by 0.5% and 0.7% respectively. These deltas are within measurement noise, so the RTX 3060 Ti is effectively tied with its closest competitors.

Q: Is the CPU or GPU the limiting component at 4K Ultra?

A: The 38.1 FPS at 4K Ultra versus 52 FPS at 4K High indicates the GPU is the constraint. If the CPU were limiting, the frame rate would remain similar across settings. The 13.9 FPS drop from High to Ultra at the same resolution is squarely a GPU rendering cost.

Q: What percentile does the Ryzen 7 5800X3D achieve relative to all CPUs?

A: The processor ranks in the 83rd percentile of all CPUs, with an average benchmark score of 26574. Its nearest rival, the AMD EPYC 8024P, scores 26555, a delta of 0.1%, while the Intel Core i9-11900K scores 26546, also 0.1% higher.

Q: How much faster is 1080p Low compared to 4K Low?

A: 1080p Low produces 191.1 FPS, while 4K Low produces 69.9 FPS. That is a 121.2 FPS difference, representing a 63% reduction in frame rate when moving from 1080p to 4K at the same settings.

Q: What does the combo’s rank of 1203 out of 1681 combos indicate?

A: This places the pairing slightly below the median of tested combinations for Doom. Given the GPU’s 69th percentile ranking and the CPU’s 83rd percentile, the lower combo rank suggests the graphics card holds back the overall capability of the processor in this title.

CPU Role

The AMD Ryzen 7 5800X3D, built on TSMC’s 7 nm process with 8,850 million transistors, provides the foundation for this system. Its 8 cores and 16 threads operate at a base clock of 3.40 GHz and boost to 4.50 GHz. The defining feature is the 96 MB of shared L3 cache, which is unusual for a desktop part and directly benefits games that repeatedly access the same data. The CPU’s benchmark results show a strong multi-threaded showing: 24063 in Cinebench R23 multi-core and 10106 in Cinebench R20 multi-core. Single-thread scores are also solid, with 3397 in Cinebench R23 single-core and 1426 in Cinebench R20 single-core.

In Doom, the CPU’s role is to prepare draw calls and physics updates. The measured frame rates at 1080p Low (191.1 FPS) indicate the 5800X3D can sustain high instruction throughput without becoming a bottleneck. The delta between the 5800X3D and its nearest rivals is negligible—0.1% above the Intel Core i9-11900K and 0.2% below the AMD Ryzen 5 7600. This suggests that any of these processors would deliver nearly identical Doom performance with the same GPU. The CPU’s 83rd percentile ranking confirms it is a high-end part, but the game’s engine does not appear to stress the 16 threads heavily, as evidenced by the 3DMark 16-thread score of 7299 versus 7285 for max threads, showing only a 0.2% difference.

The cache configuration is the key differentiator. With 96 MB of L3, the 5800X3D can hold larger portions of the game’s working set than a typical 32 MB or 16 MB design, reducing memory latency stalls. However, the frame rate data shows that this advantage does not translate into a measurable lead in Doom’s average FPS, because the GPU is the limiting component at all but the lowest settings. The CPU’s 105 W TDP and DDR4 dual-channel memory support with 51.2 GB/s bandwidth are sufficient for this title.

Measured FPS Breakdown

At 1920x1080, the resolution where the CPU has the most influence, the results are as follows: Low settings yield 191.1 FPS, Medium drops to 168.6 FPS, High produces 138.6 FPS, and Ultra falls to 115.1 FPS. The step from Low to Medium is a 22.5 FPS reduction, while the step from High to Ultra is 23.5 FPS. The consistent 20+ FPS drops per settings tier indicate that each preset adds meaningful GPU work, but even Ultra remains above 115 FPS, which is smooth for competitive play.

At 2560x1440, the pattern shifts. Low produces 124.1 FPS, Medium 105.4 FPS, High 92.3 FPS, and Ultra 76.9 FPS. The drop from Low to Medium is 18.7 FPS, and from High to Ultra is 15.4 FPS. The smaller absolute drops compared to 1080p suggest the GPU is becoming the primary limiter, as the pixel count increase consumes more of the RTX 3060 Ti’s throughput.

At 3840x2160, the results are: Low 69.9 FPS, Medium 59.3 FPS, High 52 FPS, and Ultra 38.1 FPS. The Low to Medium gap is 10.6 FPS, and the High to Ultra gap is 13.9 FPS. Notably, the Ultra preset at 4K falls below 40 FPS, which is a significant degradation from the 1080p Ultra result of 115.1 FPS. The 4K Low result of 69.9 FPS is still above the 60 FPS threshold, but the 4K Medium and High results hover near playable territory.

The data shows that for this combo, 1440p is the sweet spot: even Ultra settings maintain 76.9 FPS, and Low exceeds 120 FPS. At 1080p, the user is entirely GPU-limited, as the CPU could likely push beyond 200 FPS if the GPU allowed. The 4K Ultra result of 38.1 FPS is the only sub-40 FPS measurement, indicating that this configuration is not suited for maximum quality at 4K.

GPU Role

The NVIDIA GeForce RTX 3060 Ti, with its GA104 chip on Samsung’s 8 nm process, is the performance ceiling for this pairing. It contains 17,400 million transistors and 4864 shading units, with 152 texture mapping units and 80 ROPs. The boost clock of 1665 MHz, combined with 8 GB of GDDR6 on a 256-bit bus, yields 448.0 GB/s of memory bandwidth. The FP32 throughput of 16.20 TFLOPS is the raw compute available for Doom’s rendering tasks.

The GPU’s average benchmark score is 25120, placing it in the 69th percentile of all GPUs. Its nearest rivals are all AMD parts: the RX 6700M at 25180 (0.2% higher), the RX 6600 at 25235 (0.5% higher), and the RX 580 2048SP at 25287 (0.7% higher). These deltas are well within margin of error, meaning the RTX 3060 Ti performs comparably to its immediate competition. The PassMark G3D score of 20349 and 3DMark Steel Nomad DX12 score of 2626 provide additional context for its rasterization capabilities.

In Doom, the GPU’s role is evident in the scaling behavior. The 191.1 FPS at 1080p Low represents the peak of what this card can deliver when the engine’s rendering load is minimal. Moving to 4K Ultra at 38.1 FPS shows the card’s limits when pixel shading and memory bandwidth are fully taxed. The 8 GB VRAM is sufficient for Doom at all tested settings, as the game’s textures and effects do not appear to exceed this capacity, evidenced by the absence of stutter or frame drops in the average FPS data.

The 14 Gbps effective memory clock and 256-bit bus are critical for 4K performance. Doom’s high-resolution textures require rapid data fetching, and the 448.0 GB/s bandwidth is the bridge between the GPU’s compute units and the frame buffer. The 133.2 GPixel/s pixel rate and 253.1 GTexel/s texture rate determine how quickly the card can fill the screen with rendered geometry and apply detail. At 4K, the pixel rate becomes the binding constraint, which explains why the 4K Ultra result of 38.1 FPS is so much lower than the 1080p Ultra result. The RTX 3060 Ti is a capable 1440p card for Doom, but 4K Ultra requires more compute than its 16.20 TFLOPS can provide.
