Doom

The Intel Core i3-12100F paired with the AMD Radeon RX 7800 XT delivers a remarkably consistent experience in Doom, with the measured data showing that the game’s performance scales predictably with both resolution and graphical preset. Across all tested configurations, the combo remains playable, but the most balanced experience emerges at the High preset, which offers a substantial visual uplift over Medium while maintaining frame rates that are only modestly lower. Specifically, at 1920x1080, High produces 206.9 FPS, a drop of 36.6 FPS from Medium’s 243.5 FPS, but this difference is far less impactful than the steep 76.6 FPS penalty incurred when jumping from High to Ultra. The same pattern holds at 2560x1440, where High delivers 131.5 FPS versus 161.2 FPS on Medium, and at 3840x2160, High achieves 73.7 FPS compared to 87.8 FPS on Medium. While Ultra is technically playable at 1080p and 1440p, the 57.5 FPS result at 4K suggests that preset is best reserved for lower resolutions, making High the recommended choice for users seeking a stable, high-refresh experience without sacrificing image quality.

CPU Role

The Intel Core i3-12100F is a 4-core, 8-thread processor based on the Alder Lake architecture, with a base clock of 3.30 GHz and a boost clock of 4.30 GHz. Its benchmark profile reveals a processor that is strong in single-threaded tasks but limited in multi-threaded scaling. For instance, the 3dmark single-thread score stands at 893, while the 4-thread score reaches 2859, and the 8-thread score climbs to 4026. This pattern suggests that Doom, which is a 2016 title, likely benefits from the i3’s high boost clock rather than its core count. The data supports this interpretation: at 1080p with Low settings, the combo achieves 279.5 FPS, which is the highest measured result, indicating that the CPU is not a bottleneck when the GPU has less work to do. However, the 3dmark max-threads score of 4023 is nearly identical to the 8-thread score, implying that adding more threads beyond 8 would not yield significant gains. This is consistent with a game that was designed for the 4-core/8-thread era, and the i3-12100F’s 12 MB of shared L3 cache likely helps keep frequently accessed data close at hand. The processor’s 72nd percentile ranking among all CPUs, with an average benchmark score of 13516, places it near the AMD Ryzen Threadripper PRO 3975WX, which scores 13534, a delta of -0.1%. This suggests that while the i3 is not a top-tier chip, its performance is sufficient to feed the RX 7800 XT in Doom, especially at higher resolutions where the GPU becomes the primary driver.

GPU Role

The AMD Radeon RX 7800 XT is the dominant component in this pairing, featuring 16 GB of GDDR6 memory on a 256-bit bus, delivering 624.1 GB/s of bandwidth. Its boost clock of 2430 MHz and game clock of 2124 MHz, combined with 3840 shading units, allow it to handle Doom’s Vulkan-based rendering with ease. The GPU’s benchmark scores are telling: it achieves a 3dmark Steel Nomad DX12 score of 4157 and a passmark G3D score of 24176, placing it in the 76th percentile of all GPUs. Its nearest rival, the NVIDIA P104-100, scores 32747, a delta of -0.4%, indicating that the RX 7800 XT is slightly below that comparison point in synthetic tests. In Doom, the GPU’s role becomes increasingly apparent as resolution rises. At 1080p Low, the combo hits 279.5 FPS, but at 4K Low, it drops to 98.1 FPS. This 181.4 FPS reduction highlights how the GPU’s fill rate and memory bandwidth are taxed at higher pixel counts. The 16 GB VRAM is ample for Doom, as the game’s textures are not demanding by modern standards, but the 624.1 GB/s bandwidth ensures that even at Ultra settings, the GPU can stream data without stuttering. The 28,100 million transistors on a 5 nm process give the card a high compute density, and its 37.32 TFLOPS FP32 performance is more than sufficient for a game from 2016.

How This Combo Ranks

Out of 1681 tested combos, this pairing of the Intel Core i3-12100F and AMD Radeon RX 7800 XT ranks 639th. This position places it in the upper-middle tier of all configurations, which is notable given that the CPU is a budget-oriented part while the GPU is a high-end offering. The data suggests that the combo is not held back by the CPU at higher resolutions, as the GPU’s workload dominates. For example, at 4K Ultra, the combo produces 57.5 FPS, which is a playable result, while at 1080p Ultra, it reaches 166.9 FPS. The rank of 639 implies that there are many combos with faster CPUs or more balanced pairings, but the i3-12100F’s strong single-thread performance, as evidenced by its 3dmark single-thread score of 893, ensures that it does not cripple the RX 7800 XT. In contrast, the GPU’s 76th percentile ranking suggests that it is a top-quartile component, and the combo’s overall position reflects the CPU’s relative weakness in multi-threaded workloads. Still, for a game like Doom, which is not heavily threaded, the combo’s rank is likely higher than it would be in a more modern title that leverages many cores.

Measured FPS Breakdown

The measured FPS data provides a complete picture of this combo’s performance across resolutions and settings. At 1920x1080, the Low preset yields 279.5 FPS, Medium produces 243.5 FPS, High reaches 206.9 FPS, and Ultra drops to 166.9 FPS. Moving to 2560x1440, the results are: Low at 184.1 FPS, Medium at 161.2 FPS, High at 131.5 FPS, and Ultra at 109 FPS. At 3840x2160, the trend continues with Low at 98.1 FPS, Medium at 87.8 FPS, High at 73.7 FPS, and Ultra at 57.5 FPS. These numbers reveal a consistent pattern: the gap between Low and Ultra narrows as resolution increases. At 1080p, the difference between Low and Ultra is 112.6 FPS, but at 4K, it shrinks to 40.6 FPS. This indicates that the GPU is the limiting factor at 4K, while the CPU’s influence is more pronounced at 1080p. The data also shows that the step from High to Ultra is the most costly at every resolution, with a 40 FPS drop at 1080p, 22.5 FPS at 1440p, and 16.2 FPS at 4K.

Resolution Scaling

The scaling from 1080p to 4K is steep and predictable. At Low settings, the combo drops from 279.5 FPS at 1080p to 184.1 FPS at 1440p, a 95.4 FPS reduction, and then to 98.1 FPS at 4K, another 86 FPS drop. This pattern shows that the GPU is being pushed harder at each higher resolution, with the memory bandwidth of 624.1 GB/s becoming a critical factor. The scaling is less severe at Ultra settings: 166.9 FPS at 1080p falls to 109 FPS at 1440p, and then to 57.5 FPS at 4K. The relative drop from 1080p to 4K is 65% at Low settings, 70% at Medium, 64% at High, and 66% at Ultra. This consistency suggests that the limiting component is the GPU, as the CPU’s workload does not increase with resolution. The fact that the combo can still deliver 73.7 FPS at 4K High reflects the RX 7800 XT’s raw power, but the data also shows that the i3-12100F is not a bottleneck at higher resolutions, as the frame rates scale in a manner consistent with GPU-bound performance. For users with a 1440p monitor, the combo offers an excellent experience, with all presets except Ultra exceeding 100 FPS, while 4K users will need to stick to High or lower to maintain smooth gameplay.
