Doom

The Intel Core i5-12400F paired with the NVIDIA GeForce RTX 3070 delivers a remarkably consistent experience in Doom, with the data showing a clear progression of frame rates that scales predictably with resolution and quality settings. At 1080p High, the combo produces an average of 190.7 FPS, which rises to 256.3 FPS on Low settings, indicating that the system has substantial headroom even at the most demanding quality presets. The pattern across all tested resolutions reveals a system where the GPU becomes the primary constraint as resolution increases, while the CPU maintains sufficient throughput to avoid becoming a bottleneck even at lower resolutions.

Resolution Scaling

The measured FPS data reveals a steep and consistent decline as resolution increases from 1080p to 4K, which is characteristic of a GPU-bound scenario in Doom. At 1080p High, the system delivers 190.7 FPS, but this drops by 35.7% to 122.6 FPS at 1440p High, and then by another 47% to 65 FPS at 4K High. This scaling pattern indicates that the RTX 3070's rendering throughput is the limiting factor at higher resolutions, while the i5-12400F's six cores and twelve threads are more than sufficient to feed the GPU at lower resolutions.

The gap between Low and Ultra settings widens as resolution increases, which further confirms the GPU-bound nature of the workload at higher pixel counts. At 1080p, the difference between Low (256.3 FPS) and Ultra (155.7 FPS) is 100.6 FPS, representing a 64.6% performance drop from the lowest to the highest quality preset. At 1440p, this gap narrows to 65.9 FPS (from 169.2 FPS on Low to 103.3 FPS on Ultra), and at 4K it narrows further to 35.4 FPS (from 91.6 FPS on Low to 56.2 FPS on Ultra). This convergence at higher resolutions is a classic indicator that the GPU's pixel throughput and memory bandwidth are becoming the dominant constraints.

The 4K results are particularly telling. Even on Low settings, the system only manages 91.6 FPS, which is below the 1440p Low result of 169.2 FPS by 77.6 FPS. This substantial drop suggests that the RTX 3070's 8 GB of GDDR6 memory and 448.0 GB/s bandwidth are being heavily taxed at 3840x2160. The Ultra preset at 4K yields just 56.2 FPS, which is below the 60 FPS threshold that many users consider the minimum for smooth gameplay, indicating that this combo is best suited for 1080p and 1440p gaming in Doom rather than 4K.

GPU Role

The NVIDIA GeForce RTX 3070 is the primary driver of performance in Doom, and its specifications explain the observed scaling patterns. The GPU features a base clock of 1500 MHz and a boost clock of 1725 MHz, with 5888 shading units and 96 ROPs. These specifications translate to a pixel rate of 165.6 GPixel/s and a texture rate of 317.4 GTexel/s, which are directly relevant to Doom's fast-paced rendering demands. The 8 GB of GDDR6 memory on a 256-bit bus provides 448.0 GB/s of bandwidth, which becomes a critical factor at 4K resolutions where texture and framebuffer demands increase substantially.

The benchmark data shows that the RTX 3070's performance in Doom is consistent with its general capabilities. Its passmark G3D score of 22214 and average benchmark score of 28238 place it in the 72nd percentile among all GPUs. The nearest rivals in the database include the AMD Radeon RX 6600 XT with an average score of 27985 (0.9% lower) and the NVIDIA GeForce GTX 980 Ti with an average score of 27956 (1% lower). This positioning suggests that the RTX 3070 is a solid mid-to-high-tier performer, and the Doom results reflect this, with the GPU able to maintain high frame rates at 1080p and 1440p but struggling to maintain 60 FPS at 4K Ultra.

The GPU's memory configuration is particularly relevant to Doom's performance at higher resolutions. The 8 GB capacity is sufficient for 1080p and 1440p, but at 4K, the combination of higher resolution textures and larger framebuffers puts pressure on the memory subsystem. The 448.0 GB/s bandwidth appears to be a limiting factor at 3840x2160, as evidenced by the significant FPS drop from 1440p to 4K across all quality settings. The GPU's 220 W TDP and dual-slot design indicate a high-power component, but the data suggests that its compute throughput is well-matched to Doom's engine at resolutions up to 1440p.

How This Combo Ranks

The combo of the Intel Core i5-12400F and the NVIDIA GeForce RTX 3070 ranks 788th out of 1681 tested combinations in Doom, placing it in the 47th percentile of all tested systems. This ranking reflects a balanced configuration that performs well but is not at the top tier of the database. The rank suggests that there are 893 combos that achieve higher performance in Doom, likely featuring more powerful GPUs or CPUs, while 787 combos perform worse.

The ranking is consistent with the individual component positions. The CPU has a percentile of 77 among all CPUs, and its nearest rival is the Intel Core i7-8700K with an average score of 19210, which is just 0.1% lower than the i5-12400F's average of 19221. The GPU has a percentile of 72 among all GPUs, with its nearest rival being the AMD FirePro S7150 with an average score of 28409, which is 0.6% higher. Both components are in the upper-middle range of their respective categories, and their combination produces a system that is well-suited for high-refresh-rate gaming at 1080p and 1440p but falls short of top-tier 4K performance.

The data indicates that this combo is not a leader in the database, but it represents a competent pairing for Doom. The 788th rank out of 1681 means that roughly 53% of tested combos outperform it, which is a reasonable position for a mid-range CPU paired with a mid-to-high-range GPU. The performance gap to the top combos is likely substantial, but the measured FPS values show that this system can deliver smooth gameplay at the most common gaming resolutions.

CPU Role

The Intel Core i5-12400F plays a supporting role in Doom's performance, providing six cores and twelve threads with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. This configuration is more than adequate for Doom's engine, which is known for being well-optimized and not heavily multi-threaded. The CPU's benchmark scores reinforce this assessment: it achieves a Cinebench R23 multicore score of 16518 and a single-core score of 2332, placing it in the 77th percentile among all CPUs.

The CPU's performance relative to its rivals shows that it is a competitive mid-range part. Its average benchmark score of 19221 is nearly identical to the Intel Core i7-8700K's 19210 (0.1% difference), and it slightly outperforms the Intel Core i5-1335U with a score of 19167 (0.3% difference). The AMD Ryzen 5 7533HS scores 19364, which is 0.7% higher, and the AMD EPYC 7773X scores 18979, which is 1.3% lower. These tight margins indicate that the i5-12400F is well-positioned among its peers, and its performance in Doom reflects this balanced standing.

In Doom specifically, the CPU's role is to feed the GPU with draw calls and game logic, and the data suggests it does so without becoming a bottleneck. At 1080p Low, the system achieves 256.3 FPS, which is a high frame rate that requires significant CPU throughput. The fact that the FPS scales down as quality settings increase indicates that the GPU is the limiting factor, not the CPU. Even at 1080p Ultra, the system maintains 155.7 FPS, which is well above the refresh rate of most monitors, further confirming that the i5-12400F has sufficient headroom for this game. The CPU's 18 MB of shared L3 cache and dual-channel memory support for DDR4 and DDR5 contribute to its ability to keep the GPU fed with data, though the exact impact on Doom is not directly measured in the provided data.
