Doom

The AMD Ryzen 5 8400F and NVIDIA GeForce RTX 4070 Ti SUPER combination delivers a high-refresh-rate 1080p and 1440p experience in Doom, with 4K performance remaining surprisingly strong. This pairing leverages a 6-core, 12-thread Zen 4 processor with a 16 GB Ada Lovelace GPU to push frame rates that consistently exceed typical display refresh rates. The benchmark data indicates a system that is well-balanced for this particular title, though the CPU’s role becomes more prominent at lower resolutions and lower graphical settings.

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

The AMD Ryzen 5 8400F is built on the Zen 4 architecture and features 6 cores and 12 threads. Its base clock is 4.20 GHz, with a boost clock of 4.70 GHz, and it operates within a 65 W TDP. This processor is manufactured on a 4 nm process by TSMC and supports DDR5 memory in a dual-channel configuration, providing a memory bandwidth of 83.2 GB/s.

In synthetic benchmarks, the CPU scores 20,851 in Cinebench R23 multi-core and 2,943 in single-core. Its PassMark multithread score is 24,530, with a single-thread score of 3,684. These results place the processor in the 82nd percentile of all CPUs. When compared to its nearest rivals, the average benchmark score of 25,064 is virtually identical to the AMD Ryzen 7 2700X, which scores 25,057, resulting in a delta of 0%. It also matches the AMD Ryzen AI 5 PRO 340 (25,099, -0.1%) and the AMD EPYC 9474F (25,103, -0.2%). The closest competitor, the AMD Ryzen 5 7500F, scores 24,993, which is 0.3% lower.

For Doom, the CPU’s single-thread performance is critical, given the game’s engine is known for being responsive to high clock speeds. The boost clock of 4.70 GHz, combined with a strong single-core Cinebench R23 score of 2,943, ensures that the processor can feed the GPU efficiently. At 1080p with Low settings, the frame rate reaches 373.4 FPS, which suggests that the CPU is not a limiting factor even in less GPU-intensive scenarios. The 6-core, 12-thread configuration is sufficient for the game’s threading model, as the data shows strong scaling from the 2-thread score of 1,874 in 3DMark to the 8-thread score of 5,275, but the game does not appear to benefit significantly from the 12-thread maximum score of 6,165.

The 16 MB of shared L3 cache is a modest amount, but it is adequate for this title's working set. The processor’s 20 PCIe Gen 4 lanes provide ample bandwidth for the RTX 4070 Ti SUPER, which uses a PCIe 4.0 x16 interface. The data suggests that the Ryzen 5 8400F is a capable partner, delivering a performance level that allows the GPU to operate without significant bottlenecking in most scenarios, particularly at higher resolutions where the GPU workload dominates.

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

The NVIDIA GeForce RTX 4070 Ti SUPER is based on the Ada Lovelace architecture and the AD103 chip, manufactured on a 5 nm process. It has a base clock of 2340 MHz and a boost clock of 2610 MHz. The memory operates at 1313 MHz, with 21 Gbps effective speed. The GPU is equipped with 16 GB of GDDR6X memory on a 256-bit bus, yielding a bandwidth of 672.3 GB/s. This substantial VRAM capacity ensures that even at 4K Ultra settings, memory is not a bottleneck.

The GPU’s compute capabilities are significant, with 8,448 shading units, 264 TMUs, and 96 ROPs. It also features 66 RT cores and 264 tensor cores, which are not heavily utilized by Doom but are present for other workloads. The FP32 performance is rated at 44.10 TFLOPS. In benchmark tests, the GPU scores 31,811 in PassMark G3D and 18,372 in PassMark GPU Compute. It sits in the 86th percentile of all GPUs. Its average benchmark score of 48,704 is 0.7% higher than the NVIDIA CMP 50HX (49,071, -0.7%) and 1.6% lower than the NVIDIA RTX A2000 (47,915, 1.6%). The Intel Arc A550M scores 49,737, which is 2.1% higher.

In Doom, the GPU’s role is dominant. The frame rate scaling with resolution is clear: at 1080p High, the system achieves 275 FPS, but at 4K High, it drops to 94.1 FPS. This is a 65.8% reduction in performance when moving from 1080p to 4K, which is characteristic of a GPU-bound workload. The 16 GB VRAM prevents any texture-related performance drops, as the game’s highest settings can be accommodated. The boost clock of 2610 MHz is sustained under load, driving the high fill rates required for the game’s fast-paced action. The data confirms that this GPU is the primary performance driver in this configuration, with the CPU providing sufficient support.

The difference between Low and Ultra is 51.5 FPS. While 4K Ultra is playable, the frame rate drops below 100 FPS, which is notable for a fast-paced FPS. The data indicates that at 4K, the GPU is the limiting factor, as the CPU’s influence is diminished.

How This Combo Ranks

The combination of the AMD Ryzen 5 8400F and NVIDIA GeForce RTX 4070 Ti SUPER achieves a rank of 167 out of 1,681 tested combos in Doom. This places it in the top 10% of all configurations tested. This high ranking is primarily attributable to the GPU’s substantial compute power and memory bandwidth, which are well-suited to the game’s Vulkan-based engine.

The CPU contributes to this ranking by ensuring that the GPU is not starved of data, particularly at lower resolutions. The 1080p Low result of 373.4 FPS demonstrates that the CPU can maintain high throughput. However, the ranking reflects a system where the GPU is the dominant component. The 0.3% lead over the AMD Ryzen 5 7500F in CPU benchmarks does not translate into a significant FPS advantage in this game, as the bottleneck shifts to the GPU at higher settings.

The 167th position indicates that there are 166 configurations that perform better, likely featuring higher-end CPUs or GPUs. However, this combo’s performance is well above the median, as the total number of tested combos is 1,681. The data suggests that for Doom, this pairing provides a robust high-refresh-rate experience at 1080p and 1440p, with capable 4K performance that remains playable. The combination’s strength lies in its ability to deliver high frame rates without significant compromise, making it a formidable option for this title.
