Doom

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

The AMD Ryzen 7 5700G is an 8-core, 16-thread processor based on the Zen 3 architecture, built on TSMC's 7 nm process. It carries a base clock of 3.80 GHz and a boost clock of 4.60 GHz, with a 65 W TDP. The chip's L3 cache is 16 MB, and it supports DDR4 memory over a dual-channel bus. For a 2016 FPS title like Doom, the CPU's workload is modest, but the 5700G's single-thread performance is the key driver here.

Benchmark data shows the 5700G scores 899 in 3dMark single-thread and 2,930 in Cinebench R23 single-core. These numbers are solid for a processor of this class, placing it in the 83rd percentile among all CPUs. Its multi-threaded results are also strong — Cinebench R23 multi-core hits 20,755, and 3dMark max-threads reaches 6,627. In Doom, which is primarily GPU-bound at higher settings, the CPU's 8 cores and 16 threads are more than sufficient to feed the graphics card. The gap between single-thread and multi-thread scores suggests that the 5700G will not bottleneck the RTX 3080 Ti in this game, even at lower resolutions where frame rates climb.

The nearest rival comparisons reinforce this. The AMD Ryzen 7 6800U scores 25,706 average, a mere 0.3% ahead of the 5700G's 25,626 average. The Intel Xeon D-2752TER trails by 0.4%, and the Intel Core 5 210H is 0.5% behind. These are essentially statistical ties, meaning the 5700G's compute capability is well-matched against these alternatives. For Doom's engine, which scales well with core count but relies more on per-core efficiency, the 5700G's balance of 8 cores and strong single-thread performance keeps it out of the way of the GPU.

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

The NVIDIA GeForce RTX 3080 Ti is an Ampere-architecture GPU with 12 GB of GDDR6X memory on a 384-bit bus, delivering 912.4 GB/s of bandwidth. Its base clock is 1365 MHz with a boost of 1665 MHz, and memory runs at 19 Gbps effective. The card packs 10,240 shading units, 320 TMUs, and 112 ROPs, with 80 RT cores and 320 tensor cores. It supports DirectX 12 Ultimate and Vulkan 1.4, both relevant to Doom's Vulkan renderer.

The RTX 3080 Ti's benchmark scores reflect its high-end positioning. It posts 26,896 in Passmark G3D and 191,309 in Geekbench OpenCL, landing in the 83rd percentile among all GPUs. Its nearest rivals are extremely close: the RTX 3090 is just 0.5% ahead, the AMD Radeon Pro 5300 is 0.9% ahead, and the RTX 5070 is 1.1% ahead. The Tesla M40 trails by 1.6%. This puts the 3080 Ti at the top tier of graphics performance, which is exactly what Doom needs at high refresh rates.

In Doom, the GPU's 12 GB VRAM is ample for the game's textures, even at 4K Ultra. The measured frame rates confirm that the 3080 Ti is the dominant component in this combo. At 1080p High, the combo hits 233.8 FPS, and at 4K High it still manages 79.2 FPS. The GPU's raw throughput — 34.10 TFLOPS FP32 — translates directly into the high frame rates seen across all resolutions. The card's 350 W TDP and 750 W suggested PSU indicate it is a power-hungry part, but that is a physical requirement of its performance level.

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

The measured FPS data reveals a clear pattern of GPU-bound scaling. At 1080p High, the combo produces 233.8 FPS. Moving to 1440p High drops that to 147.7 FPS, a 36.8% reduction. At 4K High, the average falls to 79.2 FPS, which is 66.1% below the 1080p figure. This steep decline as resolution increases is the signature of a system where the GPU is the limiting factor — the CPU has enough headroom to push frames, but the graphics card's workload grows with pixel count.

The same trend appears at every settings level. At 1080p Low, the combo hits 312.7 FPS; at 1440p Low it drops to 203.9 FPS, and at 4K Low it settles at 111 FPS. The Ultra preset shows 185.5 FPS at 1080p, 123.6 FPS at 1440p, and 64.2 FPS at 4K. The percentage drop from 1080p to 4K is consistent across settings, hovering around 65-67%. This uniformity indicates that the GPU's fill rate and memory bandwidth — 186.5 GPixel/s and 912.4 GB/s respectively — are what scale with resolution, while the CPU's contribution remains constant.

The implication is that for 1080p and 1440p gaming, the 5700G is not holding the 3080 Ti back. At 1080p Low, the 312.7 FPS average is well above the refresh rate of most monitors, and even at 1440p High the 147.7 FPS is smooth. At 4K, the GPU's workload becomes the absolute bottleneck, with the CPU sitting idle more often. This is a healthy balance for a high-refresh-rate setup, though the 4K Ultra result of 64.2 FPS shows the limits of even this powerful GPU on the most demanding settings.

How This Combo Ranks — use comboRankInGame vs other tested combos

The AMD Ryzen 7 5700G + NVIDIA GeForce RTX 3080 Ti combination ranks 456th out of 1,681 tested combos in Doom. This places it in the top 27.1% of all configs in the database — a strong showing, but not a top-tier one. The rank reflects the CPU's mid-range position relative to the GPU's high-end performance. The 3080 Ti is a top-17% GPU, while the 5700G sits at the 83rd percentile among CPUs, which is above average but not elite.

The combo's ranking is influenced by the CPU's limitations at lower resolutions. At 1080p, where the CPU's single-thread performance matters more, the 5700G's 899 single-thread score in 3dMark is decent but not class-leading. Rivals like the Ryzen 7 6800U and Intel Core 5 210H are within 0.5% in average CPU score, so any difference in Doom's frame rates would be minimal. The GPU's massive lead over its rivals — the RTX 3090 is only 0.5% ahead, and the RTX 5070 is 1.1% behind — means the 3080 Ti is doing the heavy lifting for this combo's rank.

Compared to other combos, this pairing sits in the upper-middle tier. It outperforms the vast majority of tested systems, but it falls short of combos that pair the 3080 Ti with a faster CPU like a Ryzen 9 or Core i9. The data suggests that in GPU-bound scenarios at 4K, the 5700G's rank matters little — the GPU determines the outcome. But in CPU-sensitive scenes at 1080p, the combo might not extract every last frame from the 3080 Ti, which could explain why it doesn't crack the top 400.

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

The measured data provides a clear picture of how settings affect performance. At 1080p, the Ultra preset delivers 185.5 FPS, which is already far above the 144 Hz refresh rate common on high-end monitors. Dropping to High yields 233.8 FPS, and Low pushes to 312.7 FPS. The jump from Ultra to High is a 26% FPS increase, while the visual difference in Doom is often subtle at these settings. For competitive play, the Low preset at 312.7 FPS offers the smoothest experience, but for most players, High at 233.8 FPS is the sweet spot — it maintains high fidelity without sacrificing responsiveness.

At 1440p, the story is similar. High produces 147.7 FPS, which comfortably exceeds 120 Hz displays. Medium hits 177.7 FPS, and Low reaches 203.9 FPS. The Ultra preset drops to 123.6 FPS, still playable but closer to the edge of high-refresh territory. For a balance of image quality and speed, High at 1440p is the recommended choice — it delivers near-Ultra visuals with a 19.5% FPS advantage over Ultra.

At 4K, the choices become more consequential. High gives 79.2 FPS, which is smooth for a single-player FPS but below 90 FPS. Medium improves to 93.7 FPS, a 18.3% gain over High. Low reaches 111 FPS, while Ultra falls to 64.2 FPS. For 4K, the Medium preset is the optimal pick: it stays above 90 FPS, which feels responsive, while retaining enough detail to appreciate the resolution. Ultra at 64.2 FPS is playable but not ideal for fast-paced combat, and the drop from Medium to Ultra is a 31.5% FPS penalty. The data suggests that Medium at 4K is the best compromise between visual fidelity and frame rate, while High at 1080p and 1440p offers the best overall experience for this combo.
