Doom

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

The AMD Ryzen 7 5700 is an 8-core, 16-thread processor built on the Zen 3 architecture (Cezanne codename) using TSMC's 7 nm process. It operates with a base clock of 3.70 GHz and a boost clock of 4.60 GHz, with a 65 W TDP. The chip features a 16 MB L3 cache, 512 KB L2 per core, and 64 KB L1 per core. Memory support is DDR4 over a dual-channel bus, delivering 51.2 GB/s of bandwidth. The CPU sits on the AMD Socket AM4 platform with PCIe Gen 3 (20 lanes from the CPU).

For Doom, a 2016 FPS title, this processor's configuration is highly relevant. The game's id Tech 6 engine is known for scaling well across multiple threads, and the 8-core/16-thread layout provides substantial parallel headroom. In synthetic benchmarks, the CPU scores 6,628 in 3DMark with 16 threads, 5,585 with 8 threads, and 3,382 with 4 threads. The single-thread score of 901 in 3DMark and the Cinebench R23 single-core score of 2,916 indicate strong per-core performance, which matters for the game's main thread. The multi-core Cinebench R23 result of 20,655 shows the processor's aggregate capability.

The CPU's average benchmark score is 27,220, placing it in the 84th percentile of all CPUs. It sits within 0.7–1.2% of its nearest rivals: the Intel Core i9-9900K (avg score 27,043), Intel Core i7-12700H (27,006), Intel Core i7-1370P (26,991), and AMD Ryzen AI 5 340 (26,909). This tight clustering means the Ryzen 7 5700 is essentially performance-equivalent to those chips in general compute, though Doom's specific workload may favor certain characteristics. The data shows that at 1080p Low settings, the combo achieves 149.1 FPS, which suggests the CPU is not a bottleneck at lower resolutions where the GPU has less work. The PassMark single-thread score of 3,296 reinforces that the processor can feed frames quickly enough for high-refresh gaming.

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

The NVIDIA GeForce GTX 1660 SUPER is built on the Turing architecture (TU116 chip) using a 12 nm process at TSMC. It has 6 GB of GDDR6 memory on a 192-bit bus, yielding 336.0 GB/s of bandwidth. The memory clock runs at 1750 MHz (14 Gbps effective). The GPU's base clock is 1530 MHz, boosting to 1785 MHz. It packs 1,408 shading units, 88 texture mapping units, and 48 ROPs. The pixel rate is 85.68 GPixel/s, and the texture rate is 157.1 GTexel/s. Floating-point performance is 5.027 TFLOPS (FP32), with FP16 at 10.05 TFLOPS (2:1). The card has a 125 W TDP and requires a 300 W suggested PSU.

For Doom, the GTX 1660 SUPER's memory subsystem is a key factor. The 6 GB VRAM capacity is adequate for the game's textures at 1080p and 1440p, though 4K Ultra settings may stress it. The 336.0 GB/s bandwidth helps sustain high fill rates in the game's fast-paced environments. The GPU's average benchmark score is 14,286, placing it in the 55th percentile of all GPUs. Its nearest rivals are extremely close: the AMD Radeon RX Vega 11 (14,314, -0.2%), Intel Iris Xe MAX Graphics (14,315, -0.2%), AMD Radeon Vega 11 (14,352, -0.5%), and AMD Radeon RX 5500 XT (14,389, -0.7%). This indicates the GTX 1660 SUPER is a mid-pack performer, and the differences among these rivals are negligible.

In Doom, the GPU's role is dominant at higher resolutions. At 4K Ultra, the combo drops to 29.8 FPS, showing the GPU's limits. The card's DirectX 12 benchmark score of 50 (PassMark) and Vulkan score of 59,933 (Geekbench) suggest it handles modern APIs, which Doom's Vulkan path leverages effectively.

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 delivers 109.7 FPS. Moving to 1440p High drops this to 71.5 FPS, a reduction of roughly 35%. At 4K High, the FPS falls to 38.1, another ~47% drop from 1440p. This progressive decline with increasing resolution is characteristic of a GPU-limited scenario, where the GTX 1660 SUPER's rendering capacity is the constraining factor.

Looking at Low settings, the scaling is similar but at higher absolute levels. 1080p Low yields 149.1 FPS, 1440p Low gives 96.8 FPS, and 4K Low produces 49.4 FPS. The percentage drop from 1080p to 4K at Low settings is about 67%, which is slightly less severe than at High settings (65% drop from 109.7 to 38.1). This suggests that as settings increase, the GPU becomes even more of a bottleneck.

At Ultra settings, the pattern intensifies. 1080p Ultra delivers 91.3 FPS, 1440p Ultra drops to 59.9 FPS, and 4K Ultra plummets to 29.8 FPS. The 4K Ultra result is below the 30 FPS mark, indicating that this combination cannot maintain playable frame rates at the highest settings and resolution. The data shows that the CPU is not the limiting factor here; the Ryzen 7 5700's strong single-thread and multi-thread scores (3,296 PassMark single-thread, 20,655 Cinebench R23 multi-core) are more than sufficient to drive the GPU. The limiting component at 4K is clearly the GTX 1660 SUPER.

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

The measured FPS data for Doom with this CPU-GPU combo is as follows:

1080p (1920x1080):

• Low: 149.1 FPS
• Medium: 129.3 FPS
• High: 109.7 FPS
• Ultra: 91.3 FPS

At 1080p, the combo delivers smooth performance across all settings. Even at Ultra, the 91.3 FPS result exceeds 60 FPS, providing a fluid experience. The gap between Low and Ultra is about 58 FPS, showing that settings have a moderate impact at this resolution.

1440p (2560x1440):

• Low: 96.8 FPS
• Medium: 85.9 FPS
• High: 71.5 FPS
• Ultra: 59.9 FPS

At 1440p, performance remains respectable. Ultra settings just barely miss the 60 FPS threshold at 59.9 FPS, while Low and Medium easily surpass it. The drop from 1080p to 1440p is consistent across settings, averaging around 35% reduction.

4K (3840x2160):

• Low: 49.4 FPS
• Medium: 47.6 FPS
• High: 38.1 FPS
• Ultra: 29.8 FPS

At 4K, the GPU struggles. Only Low and Medium settings approach 50 FPS, while High dips to 38.1 FPS and Ultra falls below 30 FPS. The gap between Low and Ultra at 4K is nearly 20 FPS, indicating that settings dramatically affect performance at this resolution. The combo's rank in this game is 1,457 out of 1,681 combinations, placing it in the lower portion of tested configurations.
