Doom

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

The AMD Ryzen 7 5700X3D is an 8-core, 16-thread processor built on the Zen 3 architecture, codenamed Vermeer, using TSMC's 7 nm process. It operates with a base clock of 3.00 GHz and a boost clock of 4.10 GHz, drawing up to 105 W TDP. The chip features 96 MB of shared L3 cache, which is substantial for a 5000-series part and directly impacts gaming workloads that benefit from larger data residency. Its single-thread performance in synthetic tests — 804 points in 3dmark_single_thread and 3157 in Cinebench R23 single-core — indicates that per-core throughput is solid, though not class-leading. The multi-threaded results (22366 in Cinebench R23 multicore, 26318 in Passmark multithread) place it comfortably in the upper tier of desktop processors.

In Doom, the CPU's role is less about raw thread count and more about maintaining frame pacing. The game, released in 2016, is well-optimized for high refresh rates, and the 5700X3D's combination of 8 physical cores and fast cache means it can feed frames to the GPU without becoming a bottleneck at lower resolutions. The data shows that at 1080p Low, the system achieves 257.6 FPS, which is far beyond typical display refresh rates. The 3dmark_8_threads score of 5357 versus the max_threads score of 6755 suggests that scaling beyond 8 threads yields diminishing returns — a pattern consistent with a game engine that primarily leverages a handful of well-optimized threads. The CPU's percentile ranking of 82 among all processors reinforces that this is a capable gaming chip, but its nearest rivals — Intel Core i7-1360P (deltaPct 0.2), AMD Ryzen 5 7600X3D (deltaPct 0.3), Intel Core i5-11600 (deltaPct 0.5), and AMD Ryzen AI Max 385 (deltaPct -0.6) — all sit within a 1% performance envelope in average benchmark scores. This tight clustering suggests that in CPU-bound scenarios, the 5700X3D is neither dramatically ahead nor behind its direct competition.

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

The NVIDIA GeForce RTX 3070 is built on the Ampere architecture with the GA104 chip, fabricated on Samsung's 8 nm process. It packs 5888 shading units, 184 texture mapping units, and 96 ROPs, along with 46 ray tracing cores and 184 tensor cores. The GPU runs at a base clock of 1500 MHz and boosts to 1725 MHz, with 8 GB of GDDR6 memory on a 256-bit bus delivering 448.0 GB/s of bandwidth. This memory configuration is crucial for Doom at higher resolutions, as the game's texture-heavy environments can pressure VRAM capacity. The FP32 compute throughput of 20.31 TFLOPS provides ample headroom for the game's Vulkan-rendered scenes, and the GPU's DirectX 12 Ultimate support (12_2) aligns well with modern API expectations.

The RTX 3070's synthetic benchmark scores — 22214 in Passmark G3D and 123479 in Geekbench OpenCL — place it in the 72nd percentile of all GPUs. Its nearest rivals are the AMD FirePro S7150 (deltaPct -0.6), AMD Radeon RX 6600 XT (deltaPct 0.9), NVIDIA GeForce GTX 980 Ti (deltaPct 1), and AMD Radeon R9 M295X (deltaPct -1.1). The RX 6600 XT, in particular, is a direct competitor in the mainstream segment, and the 3070 edges it out by 0.9% in average benchmark scores. In Doom, the GPU becomes the primary limiter at 4K: the measured FPS drops from 257.6 at 1080p Low to 88.5 at 4K Low, a 65.6% reduction that reflects the GPU's fill rate and memory bandwidth constraints at higher pixel counts. The 8 GB VRAM is sufficient for 1080p and 1440p in this game, but at 4K Ultra the 52.4 FPS result suggests the card is working near its memory ceiling, as texture streaming and geometry complexity increase.

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

The measured FPS data reveals a clear sweet spot between visual fidelity and performance. At 1440p, the High preset delivers 125.1 FPS, which is comfortably above the 100 FPS threshold many competitive players target, while Medium offers 146.8 FPS — a 17.3% improvement over High with only a modest visual downgrade. At 1080p, the Medium preset achieves 228 FPS, which is within the range of high-refresh 240 Hz monitors, making it the optimal choice for esports-style play. The Ultra preset, while visually impressive, exacts a significant toll: at 1080p it drops to 158.5 FPS (a 30.5% reduction from Medium), and at 4K it falls to 52.4 FPS, which is below the smoothness threshold for fast-paced action.

For the best experience per the measured rows, 1440p Medium at 146.8 FPS offers the ideal balance — it maintains high frame rates while still leveraging the GPU's capabilities at a resolution that shows off the 5700X3D's strengths. At 4K, the data suggests that High (66.1 FPS) is the playable ceiling, as Ultra (52.4 FPS) dips into territory where input latency and motion smoothness degrade. Low settings at 4K (88.5 FPS) are viable but sacrifice too much visual detail for a game that shines with its atmospheric lighting and texture work. The 1080p High preset at 189.4 FPS is also worth considering for users with 144 Hz monitors who prioritize visual quality over maximum frame rates.

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

At 1920x1080, the system delivers its highest frame rates. Low settings produce 257.6 FPS, Medium drops to 228 FPS, High reaches 189.4 FPS, and Ultra bottoms out at 158.5 FPS. The delta between Low and Ultra is 99.1 FPS, or 38.5%, indicating that the GPU is the scaling factor at this resolution — the CPU has ample headroom to feed frames. The progression is smooth, with each settings tier costing roughly 15-20% performance relative to the previous one.

At 2560x1440, the pattern shifts. Low yields 168.7 FPS, Medium 146.8 FPS, High 125.1 FPS, and Ultra 102.1 FPS. The gap between Low and Ultra is 66.6 FPS (39.5%), similar in percentage to 1080p, but the absolute numbers are lower across the board. Notably, the High preset at 1440p (125.1 FPS) is still faster than the Ultra preset at 1080p (158.5 FPS) — a signal of how resolution scaling affects GPU load more than settings changes.

At 3840x2160, the frame rates compress significantly. Low produces 88.5 FPS, Medium 82.1 FPS, High 66.1 FPS, and Ultra 52.4 FPS. The difference between Low and Medium at 4K is only 6.4 FPS (7.8%), suggesting that the GPU is becoming pixel-bound rather than compute-bound. The drop from High to Ultra is 13.7 FPS (20.7%), which is steeper than the Medium-to-High drop of 16.0 FPS (19.5%). This non-linear scaling indicates that Ultra settings introduce effects that disproportionately tax the RTX 3070's memory bandwidth and shading resources at 4K.

FAQ

Q: Is the AMD Ryzen 7 5700X3D a bottleneck for the RTX 3070 in Doom at 1080p?

A: No. At 1080p Low, the system achieves 257.6 FPS, which is far beyond typical monitor refresh rates. The CPU's 8-core, 16-thread configuration with 96 MB L3 cache provides sufficient throughput, as evidenced by its 3dmark_max_threads score of 6755, which is nearly identical to its 8-thread score of 5357.

Q: How does the RTX 3070's VRAM affect Doom at 4K?

A: The 8 GB GDDR6 memory on a 256-bit bus (448.0 GB/s bandwidth) is adequate for 4K High (66.1 FPS) but becomes strained at 4K Ultra (52.4 FPS). The steep 13.7 FPS drop from High to Ultra suggests texture and geometry demands exceed the card's comfortable memory capacity at that resolution.

Q: What is the best resolution-to-settings ratio for a smooth 144 Hz experience?

A: The data indicates 1440p Medium at 146.8 FPS or High at 125.1 FPS both meet the 144 Hz target. At 1080p, Medium at 228 FPS exceeds even 240 Hz displays, while Ultra at 158.5 FPS still clears the 144 Hz mark.

Q: How does the RTX 3070 compare to the AMD Radeon RX 6600 XT in synthetic benchmarks?

A: The RTX 3070's average benchmark score is 28238, while the RX 6600 XT scores 27985, giving the NVIDIA card a 0.9% advantage. Both GPUs sit in the same performance tier, though the 3070's 20.31 TFLOPS FP32 compute is substantially higher.

Q: Does the Ryzen 7 5700X3D's single-thread performance limit Doom's frame rates?

A: The processor's 3dmark_single_thread score of 804 and Cinebench R23 single-core score of 3157 are moderate, but Doom's engine scales well across cores. The 1080p Low result of 257.6 FPS demonstrates that single-thread performance is not a limiting factor, as the game leverages multiple threads effectively.

Q: Is 4K gaming viable with this combo?

A: Yes, but with caveats. The system achieves 88.5 FPS at 4K Low and 66.1 FPS at 4K High, both playable. However, 4K Ultra at 52.4 FPS falls below the 60 FPS threshold, making High the recommended ceiling for 4K play.

How This Combo Ranks

The AMD Ryzen 7 5700X3D + NVIDIA GeForce RTX 3070 combination ranks 769th out of 1681 tested combos in Doom, placing it in the 54th percentile of all system pairings. This mid-pack ranking is somewhat surprising given the individual components' solid percentiles (CPU at 82, GPU at 72). The discrepancy suggests that Doom's optimization favors certain hardware configurations — particularly those with higher-end GPUs that can leverage the game's Vulkan rendering path more effectively. The combo's ranking indicates that while each component is competent, together they form a system that is competitive but not exceptional for this specific title.

The CPU's nearest rivals all score within 0.6% of the 5700X3D's average benchmark score, meaning the processor choice has minimal impact on the combo's overall ranking. Similarly, the GPU's nearest competitors (RX 6600 XT, GTX 980 Ti) are within 1% of its average score, so the ranking is more influenced by how the pair interacts with Doom's engine than by raw component strength. The 769th position out of 1681 suggests there are roughly 900 combos that achieve better performance in this game, likely due to superior GPU choices rather than CPU differences. For a 2020 GPU paired with a 2024 CPU, this rank reflects the GPU's age relative to newer offerings, though the measured FPS data shows the system is still highly capable for 1080p and 1440p gaming.

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

The FPS scaling across resolutions reveals a clear picture of where the bottleneck lies. Moving from 1080p Low (257.6 FPS) to 1440p Low (168.7 FPS) results in a 34.5% performance drop, while moving from 1440p Low to 4K Low (88.5 FPS) yields a 47.5% drop. The total reduction from 1080p to 4K is 65.6%. This scaling pattern is characteristic of a GPU-bound system — as pixel count increases, the RTX 3070's shading units and memory bandwidth become the limiting factor, while the CPU's role diminishes.

At 1080p, the CPU's headroom is evident: the difference between Low (257.6 FPS) and Ultra (158.5 FPS) is 99.1 FPS, which is a settings-driven penalty rather than a resolution-driven one. At 4K, the same settings comparison shows only a 36.1 FPS difference (88.5 to 52.4), indicating that the GPU is already saturated at Low settings and has less spare capacity to absorb the cost of higher quality presets. The non-linear scaling at 4K — where Low to Medium costs only 6.4 FPS but High to Ultra costs 13.7 FPS — suggests that Ultra settings introduce shader complexity that disproportionately impacts the GPU's 20.31 TFLOPS compute capacity.

The data implies that this combo is best suited for 1080p and 1440p gaming, where the CPU can feed the GPU effectively and the GPU has enough bandwidth to maintain high frame rates. At 4K, the system remains playable but requires settings compromises, confirming that the RTX 3070 — with its 8 GB VRAM and 448.0 GB/s bandwidth — is the limiting component at higher resolutions, while the Ryzen 7 5700X3D's 96 MB L3 cache and 8-core design provide ample support at lower resolutions.
