Doom

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 7600X is a six-core, twelve-thread processor from the Zen 4 Raphael family, built on TSMC's 5 nm process. It runs at a base clock of 4.70 GHz and boosts to 5.30 GHz, which provides the kind of high single-thread throughput that first-person shooters favor. The CPU's cache layout includes 64 KB of L1 per core, 1 MB of L2 per core, and a shared 32 MB L3 pool. That 32 MB of shared cache is directly relevant to Doom's performance profile, as the game's engine frequently reuses the same geometry and texture data across frames.

Looking at synthetic benchmarks, the 7600X scores 3,406 in Cinebench R23 single-core and 24,128 in multi-core. In Geekbench, it posts 2,892 single-core and 12,905 multi-core. The single-thread numbers are the more telling ones for Doom, which scales well with per-core performance but has a ceiling on how much parallel work it can feed to the CPU. The 3DMark results show a pattern: 1,060 single-thread, 2,028 at 2 threads, 3,796 at 4 threads, 5,715 at 8 threads, and 6,845 at max threads. Notice how the scaling from 8 threads to max threads adds only about 1,130 points — that is a sign of diminishing returns beyond eight threads, which matches Doom's engine behavior. The game does not aggressively saturate more than a handful of cores, so the 7600X's strength in low-threaded workloads is what keeps frame pacing consistent.

The CPU's percentile rank against all processors sits at 83, and its average benchmark score is 26,272. The nearest rivals are all close: the AMD Ryzen 7 PRO 6850U scores 26,262 (0% delta), the Ryzen 7 7735U scores 26,305 (-0.1% delta), the Ryzen 5 PRO 5655GE scores 26,320 (-0.2% delta), and the Ryzen 7 5700X scores 26,214 (0.2% delta). The 7600X is effectively neck-and-neck with these parts in aggregate CPU performance, but for Doom specifically, the 5.30 GHz boost clock gives it an edge in the frame-time-sensitive scenes that depend on single-core responsiveness.

At 1080p, the CPU has to work harder to keep up with the GPU because the render load is lower. The measured FPS at 1920x1080 Low is 189.4, which is high enough that the CPU's thread scheduling and cache hits matter more than at 4K. The 32 MB L3 is ample for Doom's working set, and the dual-channel DDR5 memory bus at 83.2 GB/s provides sufficient bandwidth to feed the six cores without stalling. In short, the 7600X is not the bottleneck in this pairing for most of the measured settings; it has the headroom to push the GPU to its limits at lower resolutions.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 3060 Ti is an Ampere-generation card built on Samsung's 8 nm process, with a GA104 chip containing 17,400 million transistors on a 392 mm² die. It runs at a base clock of 1410 MHz and boosts to 1665 MHz, with memory clocked at 1750 MHz (14 Gbps effective). The 8 GB of GDDR6 memory sits on a 256-bit bus, yielding 448.0 GB/s of bandwidth — a figure that matters for Doom's texture streaming at higher resolutions and settings.

The card has 4,864 shading units, 152 TMUs, and 80 ROPs, along with 38 RT cores and 152 tensor cores. Its fillrate specs are 133.2 GPixel/s pixel rate and 253.1 GTexel/s texture rate. Compute throughput is 16.20 TFLOPS for both FP32 and FP16. In synthetic tests, the 3060 Ti scores 20,349 in Passmark G3D and 10,006 in GPU compute. Its percentile rank against all GPUs is 69, with an average benchmark score of 25,120. The nearest rivals are the AMD Radeon RX 6700M at 25,180 (-0.2% delta), the RX 6600 at 25,235 (-0.5% delta), the Radeon 890M at 25,246 (-0.5% delta), and the RX 580 2048SP at 25,287 (-0.7% delta). This places the 3060 Ti in the upper-mid range of GPUs, which is consistent with how it performs in Doom.

The 8 GB VRAM is sufficient for Doom at all tested settings, though it becomes a tighter fit at 4K Ultra where the game's high-resolution textures and post-processing effects demand more memory. The 448.0 GB/s bandwidth is the key spec for this title: Doom's id Tech 6 engine is known for aggressive texture compression and streaming, and that bandwidth allows the card to keep textures resident without hitchy loading. At 4K Ultra, the measured 40.8 FPS suggests the GPU is the limiting factor — the 16.20 TFLOPS compute and 133.2 GPixel/s fillrate are not enough to maintain 60 FPS at that extreme setting, regardless of what the CPU can deliver.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the AMD Ryzen 5 7600X and NVIDIA GeForce RTX 3060 Ti ranks 1,229 out of 1,681 tested combos in Doom. That places it in the 73rd percentile of all pairings in this database — a solidly above-average position, but not near the top tier. The rank reflects that this combo sits in a crowded mid-range segment where many other CPU-GPU pairings produce similar FPS numbers.

What the rank does not tell you directly is where the bottlenecks lie. The 3060 Ti's percentile rank of 69 versus the 7600X's percentile of 83 suggests the GPU is the weaker link in this pairing for Doom. The combo rank of 1,229 out of 1,681 is consistent with that interpretation: it is lower than what the CPU alone would suggest, because the GPU caps the frame rate at higher settings and resolutions. At 1080p Low, the combo reaches 189.4 FPS, which is near the practical ceiling for a 3060 Ti in this engine; pushing higher would require a faster GPU, not a faster CPU.

Compared to other combos in the same rank range, this pairing is balanced enough to avoid severe stutter or frame-time spikes, but it will not compete with high-end GPUs at 4K. The data indicates that the 7600X has headroom to spare — if you swapped in a stronger GPU, the CPU would not hold it back in Doom. Conversely, upgrading the CPU while keeping the 3060 Ti would yield minimal gains in this game, as the FPS numbers are GPU-bound in most scenarios.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the combo delivers strong results across all settings. Low settings produce 189.4 FPS, Medium drops to 168.9 FPS, High comes in at 141.8 FPS, and Ultra settles at 115.7 FPS. The gap between Low and Ultra is 73.7 FPS, which represents a 39% reduction from the Low baseline. That is a relatively modest penalty, indicating that the GPU has enough bandwidth and compute to handle the extra effects without collapsing.

Moving to 2560x1440, the numbers scale down proportionally. Low settings yield 125.3 FPS, Medium hits 106.0 FPS, High reaches 89.5 FPS, and Ultra drops to 74.2 FPS. The spread from Low to Ultra is 51.1 FPS, which is a 41% reduction — similar to the 1080p pattern. The fact that the percentage drop is nearly identical between 1080p and 1440p suggests the GPU is scaling predictably with resolution, and the CPU is keeping pace without introducing a secondary bottleneck.

At 3840x2160, the performance takes a significant hit. Low settings produce 69.5 FPS, Medium drops to 58.2 FPS, High falls to 48.8 FPS, and Ultra bottoms out at 40.8 FPS. The Low-to-Ultra spread is 28.7 FPS, which is a 41% reduction from Low — again matching the pattern. However, the absolute numbers are lower, and only the Low preset stays above 60 FPS. The 4K results are clearly GPU-bound, as the 3060 Ti's 448.0 GB/s bandwidth and 16.20 TFLOPS compute are stretched thin by the 8.3 million pixels per frame.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The scaling from 1080p to 4K reveals a consistent pattern across all settings. At Low settings, the FPS drops from 189.4 at 1080p to 125.3 at 1440p (a 34% reduction) and then to 69.5 at 4K (a 45% reduction from 1440p). The total drop from 1080p to 4K at Low is 119.9 FPS, which is a 63% decrease. At Medium, the drop is from 168.9 to 106.0 to 58.2 — a 66% total decrease. At High, it goes from 141.8 to 89.5 to 48.8 — a 66% decrease. At Ultra, from 115.7 to 74.2 to 40.8 — a 65% decrease.

The near-constant percentage drop across settings indicates that the scaling is primarily resolution-driven, not settings-driven. If the CPU were the limiting factor, you would expect the percentage drop to shrink as you move to 4K, because the CPU would have more time per frame to do its work. Instead, the FPS falls in near-linear proportion to the pixel count increase, which is the signature of a GPU-bound scenario. The 4K pixel count is 4 times that of 1080p, and while the FPS does not drop to exactly one-quarter, it drops enough to show that the GPU's fillrate and bandwidth are the constraining resources.

This is not a CPU bottleneck scenario. The 7600X's single-thread score of 3,406 in Cinebench R23 and its 5.30 GHz boost clock are more than adequate for Doom's engine at any resolution. The data suggests that the 3060 Ti is the limiting component at 1440p and 4K, while at 1080p the combo is balanced enough that both parts contribute to the final FPS. If you are targeting 4K gaming with this combo, the 40.8 FPS at Ultra and 48.8 FPS at High are not ideal for a fast-paced FPS; you would need to drop to Low or Medium to approach 60 FPS.

Settings Recommendations — which preset gives the best experience per the measured rows

For 1080p, the High preset at 141.8 FPS offers the best balance of visual fidelity and performance. The jump from High to Ultra costs 26.1 FPS (from 141.8 to 115.7), which is an 18% penalty for what is typically a marginal visual improvement in Doom. Medium at 168.9 FPS is smoother but the visual downgrade from High is noticeable in texture filtering and shadow quality. If you have a 144 Hz monitor, High's 141.8 FPS is close enough to the refresh ceiling that you will not notice the difference; if you have a 165 Hz panel, Medium at 168.9 FPS is the safer pick to stay above the refresh rate.

At 1440p, High at 89.5 FPS is the sweet spot. It delivers a smooth experience for a 60 Hz or 75 Hz monitor, and the gap to Ultra at 74.2 FPS is 15.3 FPS — a 17% reduction that is not worth the visual gain. Medium at 106.0 FPS is also viable if you prefer higher frame rates, but High preserves more of the game's texture detail at a resolution where that detail is more visible. Low at 125.3 FPS is excessive for this resolution and leaves visual quality on the table.

At 4K, the choices are more constrained. Low at 69.5 FPS is the only preset that stays above 60 FPS, and it does so by a margin of just 9.5 FPS. Medium at 58.2 FPS is borderline playable but will dip below 60 in heavy combat scenes. High at 48.8 FPS and Ultra at 40.8 FPS are not recommended for a game that rewards fast reactions — the frame pacing will suffer during intense firefights. If you are on a 4K display, set the game to Low and accept the visual trade-off, or consider reducing the resolution to 1440p to unlock the High preset. The data shows that this combo is not a 4K Ultra machine for Doom; it is a 1080p High or 1440p High pairing that can handle 4K only at the lowest settings.
