Doom

The Intel Core i3-12100F paired with the NVIDIA GeForce RTX 5070 delivers a compelling 1080p and 1440p experience in Doom, but the data suggests a clear sweet spot for settings. At 1920x1080, the Ultra preset still achieves an average of 201.7 FPS, which is remarkably high, but the jump to Low yields 341.7 FPS—a massive 69% performance uplift over Ultra. For competitive play, the Low preset at 1080p maximizes headroom, but the Medium preset at 294.9 FPS offers a balance of visual fidelity and speed that is hard to ignore. The High preset at 249.3 FPS remains far above refresh-rate limits for most monitors. Moving to 2560x1440, the pattern holds: Low produces 221.2 FPS, Medium drops to 190.9 FPS, and High sits at 159.3 FPS. At this resolution, the High preset is the optimal recommendation, as it still exceeds 144 Hz while maintaining better image quality. At 4K, the story changes dramatically; Ultra falls to 72.6 FPS, which is borderline for high-refresh displays, while High manages 86 FPS. For 4K, the Medium preset at 105.1 FPS provides the best experience, as it stays comfortably above 100 FPS without the steep cost of Ultra. The data shows that this combo is best utilized at 1440p High for a premium experience or 1080p Low for maximum frame rates.

CPU Role

The Intel Core i3-12100F is a 4-core, 8-thread processor from the Alder Lake family, with a base clock of 3.30 GHz and a boost clock of 4.30 GHz. Its L3 cache is 12 MB shared, and it supports DDR4 and DDR5 memory. The benchmark results indicate that this CPU is a capable performer for its class, scoring 11,912 in Cinebench R23 multi-core and 1,681 in single-core. In the context of Doom, a game from 2016, the CPU's role is crucial for maintaining high frame rates, especially at lower resolutions where the GPU is less stressed. The data shows that at 1080p, the combo reaches 341.7 FPS on Low settings, which suggests that the i3-12100F is not a bottleneck at that level. The single-thread score of 893 in 3DMark single-thread and 2,224 in Geekbench single-core indicate strong per-core performance, which is essential for a game like Doom that relies heavily on a few threads. The CPU sits at the 72nd percentile versus all CPUs, with an average benchmark score of 13,516, placing it close to the AMD Ryzen Threadripper PRO 3975WX, which scores 13,534 (a -0.1% delta), and the Intel Core i7-7700K at 13,280 (a 1.8% delta). The 4-core design with 8 threads is sufficient for Doom's engine, which was optimized for the hardware of its era. However, the data reveals that at 1440p and 4K, the frame rates drop significantly—from 341.7 FPS at 1080p Low to 221.2 FPS at 1440p Low and 120 FPS at 4K Low. This scaling indicates that while the CPU can push high frames at 1080p, the GPU becomes more of a limiting factor as resolution increases, though the CPU still holds up well. The i3-12100F's boost clock of 4.30 GHz is a key asset, providing the responsiveness needed for Doom's fast-paced action without causing frame pacing issues.

GPU Role

The NVIDIA GeForce RTX 5070 is a Blackwell 2.0 architecture GPU with 12 GB of GDDR7 memory on a 192-bit bus, delivering 672.0 GB/s of bandwidth. It has a base clock of 2325 MHz and a boost clock of 2512 MHz, with 6144 shading units and 192 tensor cores. The GPU's 3DMark Steel Nomad DX12 score of 5,077 and Passmark G3D score of 29,137 place it in the 83rd percentile versus all GPUs, with an average benchmark score of 41,687. In Doom, the GPU's role is dominant at higher resolutions, as evidenced by the measured FPS. At 4K Ultra, the combo drops to 72.6 FPS, which is a significant 71% decrease from 1080p Low, highlighting the GPU's workload at higher pixel counts. The 12 GB VRAM is ample for Doom, which is not a VRAM-heavy title, but the GPU's raw compute power is what drives the frame rates. The RTX 5070's nearest rivals in the benchmark database include the AMD Radeon Pro 5300 (41,610, a 0.2% delta) and the NVIDIA GeForce RTX 3090 (41,441, a 0.6% delta), showing that it performs in a similar bracket to a previous generation flagship. The data shows that at 1080p, the GPU is not the bottleneck, as the CPU and GPU together achieve over 300 FPS on Low settings. However, at 4K, the GPU becomes the clear limiting factor, with the FPS dropping to 120 on Low and 72.6 on Ultra. The RTX 5070's 30.87 TFLOPS FP32 performance is more than sufficient for Doom's id Tech 6 engine, which scales well with GPU power. The GPU's 48 RT cores are not heavily utilized in this game, as Doom lacks ray tracing, but the raw rasterization performance is what matters. The boost clock of 2512 MHz ensures consistent performance, and the 672 GB/s memory bandwidth prevents any bandwidth limitations even at 4K.

How This Combo Ranks

The combination of the Intel Core i3-12100F and the NVIDIA GeForce RTX 5070 ranks 336th out of 1,681 tested combos in Doom, placing it in the top 20% of all configurations tested. This rank is impressive given the CPU's modest specifications, as the i3-12100F is an entry-level part with a 58 W TDP. The ranking reflects the GPU's strength, which compensates for the CPU's limitations. The combo's position suggests that it outperforms many systems with higher-end CPUs but weaker GPUs, as Doom is heavily GPU-bound at higher resolutions. The data indicates that the RTX 5070 is the star of this pairing, and the i3-12100F is sufficient to keep up without holding the GPU back at 1440p and below. At 1080p, the combo's performance is exceptional, with the Low preset hitting 341.7 FPS, which is likely near the top of the charts for pure frame rate. The rank of 336 out of 1,681 combos means that there are 335 configurations that perform better, likely featuring higher-end CPUs like the i7 or i9 series, but the delta is not specified. The CPU's average benchmark score of 13,516 is only 0.1% behind the AMD Ryzen Threadripper PRO 3975WX, which is a vastly more expensive and powerful processor, but in Doom, the i3-12100F holds its own. The combo's performance in Doom reflects the game's optimization, as it can run on a wide range of hardware. The data shows that this pairing is well-balanced for 1080p and 1440p gaming, where the CPU and GPU are both utilized effectively. At 4K, the combo still ranks respectably, but the GPU's workload increases, and the CPU's role diminishes, as evidenced by the frame rate drops.

Resolution Scaling

The measured FPS data reveals a clear pattern of performance scaling as resolution increases. At 1080p Low, the combo achieves 341.7 FPS, which drops to 221.2 FPS at 1440p Low—a 35% decrease—and further to 120 FPS at 4K Low, a 65% decrease from 1080p. This scaling is typical for a GPU-bound scenario, where the RTX 5070's rendering workload increases with pixel count. The High preset shows a similar trend: 249.3 FPS at 1080p, 159.3 FPS at 1440p (a 36% drop), and 86 FPS at 4K (a 65% drop). The frame rate drops from 1080p to 4K are consistent across all presets, indicating that the GPU is the primary limiting factor at higher resolutions. The data shows that the CPU's performance is sufficient to maintain high frame rates at 1080p, but as resolution increases, the GPU's workload dominates, and the FPS scales down accordingly. Specifically, the drop from 1080p to 1440p is about 35-36% across presets, and the drop from 1440p to 4K is about 45-46% (e.g., 159.3 to 86 FPS on High is a 46% drop). This suggests that the RTX 5070's memory bandwidth of 672 GB/s is adequate, but the pixel throughput becomes a bottleneck at 4K. The Ultra preset at 4K (72.6 FPS) is the most demanding, showing a 64% drop from 1080p Ultra (201.7 FPS). The scaling analysis indicates that for this combo, 1080p is where the CPU and GPU work in balance, 1440p is the sweet spot for high-refresh monitors, and 4K is playable but requires lower settings to maintain 100+ FPS. The data confirms that the limiting component shifts from being balanced at 1080p to clearly GPU-bound at 4K, as the CPU's frame rate ceiling is well above what the GPU can deliver at higher resolutions.
