Doom

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

The AMD Ryzen 5 5600X is a 6-core, 12-thread processor built on the Zen 3 architecture (Vermeer codename) using a 7 nm TSMC 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 CPU's cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and a 32 MB L3 cache. Memory support is DDR4 with dual-channel configuration and a bandwidth of 51.2 GB/s. The processor also supports ECC memory and connects via PCIe Gen 4 with 20 lanes.

In synthetic benchmarks, the Ryzen 5 5600X demonstrates strong single-threaded performance, scoring 917 in 3dmark_single_thread, 1541 in cinebench_r23_singlecore, and 1989 in geekbench_singlecore. Multi-threaded results are equally solid: 5588 in 3dmark_max_threads, 11838 in cinebench_r23_multicore, and 9173 in geekbench_multicore. The CPU's average benchmark score is 21771, placing it in the 75th percentile of all CPUs tested. Its nearest rivals are tightly clustered: the AMD Ryzen 7 4800H trails by only 0.1%, while the AMD Ryzen 5 PRO 6650U and Intel Core i7-11700 are each 0.5% behind, and the AMD EPYC 9554P is 0.6% behind.

For Doom, a fast-paced FPS, the single-thread performance matters significantly because the game's engine often relies on a primary rendering thread. The 5600X's strong single-core scores (917 in 3dmark_single_thread) suggest that this CPU will not bottleneck the GPU in most scenarios. The 12 threads also provide headroom for background tasks and the game's secondary threads. Given that the game is from 2016 and designed for that era's hardware, the 5600X's capabilities far exceed what the game was originally optimized for, which is evident in the measured FPS results.

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, manufactured on Samsung's 8 nm process. It features 5888 shading units, 184 TMUs, 96 ROPs, 46 RT cores, and 184 tensor cores. The GPU has a base clock of 1500 MHz and a boost clock of 1725 MHz, with memory running at 1750 MHz (14 Gbps effective). The 8 GB GDDR6 memory sits on a 256-bit bus, providing 448.0 GB/s of bandwidth. Pixel rate is 165.6 GPixel/s, texture rate is 317.4 GTexel/s, and FP32 performance is 20.31 TFLOPS.

The RTX 3070's benchmark results show a passmark_g3d score of 22214 and an average benchmark score of 17208, placing it in the 61st percentile of all GPUs. Its nearest rivals include the AMD Radeon RX 7600 XT (0.7% ahead), the NVIDIA GeForce GTX 690 (1% ahead), the AMD Radeon HD 7970M (1.1% ahead), and the NVIDIA Tesla K40c (1.5% behind). The 8 GB VRAM is more than sufficient for Doom, a title not known for extreme memory demands, even at 4K with high settings.

The GPU's 448 GB/s memory bandwidth is critical for Doom's texture streaming. The game's id Tech 6 engine uses a virtual texture system that requires rapid data access. The RTX 3070's bandwidth, combined with its 20.31 TFLOPS of FP32 compute, allows it to handle the game's demanding effects and high-resolution textures without issue. The boost clock of 1725 MHz ensures that the GPU maintains consistent performance under load.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the AMD Ryzen 5 5600X and NVIDIA GeForce RTX 3070 ranks 1596 out of 3712 tested combos in Doom. This places the pairing in the 43rd percentile of all tested configurations, meaning roughly 43% of all combinations outperform it while 57% fall behind. This ranking reflects a mid-to-upper-tier position, which is expected given that Doom is a 2016 title that can be highly optimized for modern hardware.

The ranking position suggests that while this combo delivers high frame rates at most resolutions, there are many other combinations that achieve even higher performance. This is likely because Doom's engine is well-optimized and can scale effectively with both CPU and GPU improvements. The data indicates that the RTX 3070, while being a capable GPU, is not at the very top of the performance hierarchy, and the 5600X, though strong, is not the absolute fastest CPU available. Together, they form a balanced pairing that sits comfortably in the upper-middle range of all tested configurations.

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

At 1080p, the combo delivers very high frame rates across all settings. With Low settings, the average FPS is 258. Medium settings yield an average of 225 FPS, with a minimum of 191 and a maximum of 258. High settings produce an average of 190 FPS. Ultra settings bring the average down to 155 FPS. These numbers indicate that at 1080p, the system is primarily GPU-limited, as the CPU can easily feed the GPU at these high frame rates.

Moving to 1440p, the frame rates remain strong but show a noticeable drop from 1080p. Low settings average 167 FPS. Medium settings average 145 FPS, with a minimum of 124 and a maximum of 167. High settings average 123 FPS. Ultra settings produce an average of 100 FPS. The scaling from 1080p to 1440p shows a consistent reduction of roughly 35-40% across settings, which aligns with the increased pixel count.

At 4K, the frame rates drop more significantly. Low settings average 90 FPS. Medium settings average 79 FPS, with a minimum of 67 and a maximum of 91. High settings average 67 FPS. Ultra settings bring the average down to 54 FPS. These numbers show that at 4K, the RTX 3070 is heavily loaded, and the frame rates are still playable but significantly lower than at lower resolutions.

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

The FPS drop from 1080p to 4K is substantial. At Low settings, the average FPS drops from 258 at 1080p to 167 at 1440p (a 35.3% decrease), and then to 90 at 4K (a 46.1% decrease from 1440p, or 65.1% from 1080p). At Medium settings, the progression is 225 to 145 to 79, representing drops of 35.6% and 45.5% respectively. High settings show 190 to 123 to 67, with drops of 35.3% and 45.5%. Ultra settings show 155 to 100 to 54, with drops of 35.5% and 46.0%.

This pattern indicates that the GPU is the primary limiting component across all resolutions. The consistent percentage drops from 1080p to 1440p (approximately 35%) and from 1440p to 4K (approximately 46%) align closely with the pixel count increases (1.78x and 2.25x respectively). If the CPU were the bottleneck, we would expect to see smaller FPS differences at higher resolutions, as the GPU would have more time to wait for the CPU. Instead, the frame rates scale almost perfectly with resolution, confirming that the RTX 3070 is the limiting factor in this configuration.

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

Based on the measured data, the best experience depends on the user's resolution and refresh rate. At 1080p, High settings at 190 FPS average provides a good balance between visual quality and performance, easily exceeding 144 Hz refresh rates. Ultra settings at 155 FPS also remain viable for 144 Hz displays, offering maximum visual fidelity. For 240 Hz displays, Medium settings at 225 FPS would be the better choice, as it clears that threshold while still providing good visuals.

At 1440p, High settings at 123 FPS is the sweet spot for 120 Hz displays, while Medium settings at 145 FPS works for 144 Hz panels. Ultra settings at 100 FPS still provides a smooth experience for 100 Hz displays. For 4K, High settings at 67 FPS is the recommended preset, as it stays above 60 FPS and offers good visual quality. Medium settings at 79 FPS is even better for those with 75 Hz displays, but the jump to High is modest in terms of FPS cost (12 FPS) for a significant visual upgrade. Ultra settings at 54 FPS is below the 60 FPS threshold and is not recommended for smooth gameplay.
