Doom

The Intel Core i5-12400F paired with the NVIDIA GeForce RTX 3080 Ti lands at rank 430 out of 1681 tested combos in Doom, placing it in the top 26% of all configurations measured for this title. That is a strong showing for a mid-range CPU paired with a high-end GPU, and the data confirms the pairing is well-balanced for this game, which rewards both high frame rates and high refresh rate displays. The combo’s position in the overall rankings reflects the fact that Doom is a title where the GPU typically dominates the workload, but the i5-12400F’s 6-core, 12-thread design with a boost clock of 4.40 GHz is more than sufficient to keep feeding the graphics card, avoiding the CPU bottleneck that can plague lesser processors in this fast-paced shooter.

How This Combo Ranks

The combo’s rank of 430 out of 1681 tested configurations places it comfortably in the upper quartile of all systems benchmarked for Doom. The i5-12400F itself sits at the 77th percentile among all CPUs tested in the database, with an average benchmark score of 19221. Its nearest rival, the Intel Core i7-8700K, scores 19210, putting the i5 just 0.1% ahead, which is effectively a tie in raw CPU compute. The AMD Ryzen 5 7533HS scores 19364, a 0.7% edge over the i5, while the AMD EPYC 7773X trails by 1.3% with a score of 18979. These tiny margins indicate the i5-12400F is right in the sweet spot of mid-range desktop performance, and in Doom specifically, the CPU’s strong single-thread performance (3dmark_single_thread score of 909) ensures that the game’s engine, which relies heavily on a few primary threads, runs without hiccups.

On the GPU side, the RTX 3080 Ti holds the 83rd percentile among all GPUs, with an average benchmark score of 41224. Its nearest rival, the RTX 3090, scores 41441, which is just 0.5% higher, meaning the 3080 Ti is essentially on par with the top-tier 3090 in this database’s aggregate metrics. The AMD Radeon Pro 5300 and RTX 5070 score 41610 and 41687, respectively, putting them 0.9% and 1.1% ahead, while the Tesla M40 trails at 41897, 1.6% behind. The takeaway is clear: the 3080 Ti is a flagship-class GPU, and when paired with the 12400F, the combination is not leaving meaningful performance on the table in Doom, as evidenced by its top-quartile ranking.

GPU Role

The RTX 3080 Ti is built on the Ampere architecture with the GA102 chip, fabricated on Samsung’s 8 nm process with 28,300 million transistors. It comes with 12 GB of GDDR6X memory on a 384-bit bus, delivering 912.4 GB/s of bandwidth, which is critical for high-resolution textures and rapid asset streaming in Doom’s hellish environments. The GPU’s base clock is 1365 MHz, boosting to 1665 MHz, with memory running at an effective 19 Gbps. These clocks, combined with 10240 shading units, 80 RT cores, and 320 tensor cores, yield 34.10 TFLOPS of FP32 compute, making the card overkill for Doom at most settings—but that overkill translates directly into the high frame rates measured.

In this game, the GPU’s role is to push pixels as fast as possible, and the data shows it does so admirably. The 3080 Ti’s nearest rival, the RTX 3090, is only 0.5% faster in aggregate benchmarks, yet the 3080 Ti often matches or exceeds it in real-world gaming due to its slightly higher boost behavior. For Doom, the 12 GB VRAM is ample, and even at 4K Ultra, the game’s textures and effects do not come close to exhausting the frame buffer. The GPU’s 186.5 GPixel/s pixel rate and 532.8 GTexel/s texture rate ensure that even the most chaotic combat scenes with multiple demons and particle effects are rendered without dropping below playable thresholds.

Q: Is the RTX 3080 Ti overkill for 1080p gaming?

A: For 1080p, yes. At 1080p High, the combo hits 230.5 FPS, and at Low it reaches 314.3 FPS, far beyond any 1080p monitor’s refresh rate. You would be GPU-bound even at 1440p, making 4K the only resolution where the card is fully utilized.

Measured FPS Breakdown

The measured data provides a complete picture across three resolutions and four settings levels. At 1080p, the combo starts at 314.3 FPS on Low, drops to 275.3 FPS on Medium, 230.5 FPS on High, and 189.1 FPS on Ultra. These numbers are all far above the 144 Hz refresh rate common on 1080p monitors, meaning the limiting factor is almost certainly the CPU at the lowest settings, as the GPU is not being stretched. Moving to 1440p, the frame rates remain high: 200.5 FPS on Low, 175.8 FPS on Medium, 147.1 FPS on High, and 120.9 FPS on Ultra. The 1440p High result is the standout, as it clears 144 FPS, making it ideal for high-refresh 1440p panels. At 4K, the numbers become more demanding: 113.1 FPS on Low, 97.9 FPS on Medium, 83 FPS on High, and 67.7 FPS on Ultra. The 4K High figure is the most practical for a smooth experience, while Ultra dips below the 70 FPS threshold that many players consider comfortable for a shooter.

The progression from Low to Ultra at each resolution shows a consistent performance cost. At 1080p, the drop from Low to Ultra is 125.2 FPS, a 39.8% reduction. At 1440p, the gap is 79.6 FPS, a 39.7% reduction. At 4K, the gap is 45.4 FPS, a 40.1% reduction. This consistency indicates that the settings scaling is uniform across resolutions, with Ultra costing roughly 40% of the Low setting’s frame rate. The GPU’s 12 GB VRAM and 912.4 GB/s bandwidth are sufficient to handle the increased texture loads at 4K without introducing stutter, as evidenced by the smooth average FPS readings.

Resolution Scaling

The data reveals a clear pattern in how frame rates scale from 1080p to 4K. At High settings, the combo delivers 230.5 FPS at 1080p, 147.1 FPS at 1440p, and 83 FPS at 4K. The drop from 1080p to 1440p is 83.4 FPS, a 36.2% reduction, while the drop from 1440p to 4K is 64.1 FPS, a 43.5% reduction. This scaling indicates that the GPU is becoming the bottleneck as resolution increases, which is expected given that the RTX 3080 Ti’s compute and memory bandwidth are being taxed more heavily. The CPU’s impact diminishes at higher resolutions, as the frame rate is increasingly limited by pixel throughput rather than draw call processing.

At Low settings, the scaling is even more pronounced: 314.3 FPS at 1080p, 200.5 FPS at 1440p, and 113.1 FPS at 4K. The 1080p to 1440p drop is 113.8 FPS (36.2%), and the 1440p to 4K drop is 87.4 FPS (43.6%). The fact that the percentage drops are nearly identical across settings suggests that the GPU’s rasterization throughput is the primary limiter, not the CPU or memory bandwidth. The 3080 Ti’s 34.10 TFLOPS of FP32 compute and 186.5 GPixel/s pixel rate are the defining specs here, and they scale predictably with resolution. At 4K, the GPU is working at near its full capacity, as evidenced by the 83 FPS at High, which is a solid result for a 2016 title that is not particularly demanding by modern standards.

Settings Recommendations

For the best balance of visual quality and frame rate, the data points to 1440p High as the optimal configuration. At 147.1 FPS, this setting clears the 144 Hz threshold, providing buttery-smooth gameplay on high-refresh monitors without sacrificing the visual fidelity that Doom’s detailed environments deserve. If you are playing on a 4K display, High settings at 83 FPS are the best choice, as Ultra drops to 67.7 FPS, which is noticeably less fluid in fast-paced combat. The jump from Low to Medium at 4K is 15.2 FPS (from 113.1 to 97.9), while the jump from Medium to High is 14.9 FPS (from 97.9 to 83), indicating that each step up in quality costs roughly 15 FPS at this resolution.

For 1080p users, the recommendation is to use Ultra settings, as the 189.1 FPS average is still far above any practical refresh rate, and the visual improvements are worth the frame rate cost. The data shows that even at 1080p Ultra, the combo is not CPU-limited, as the 12400F’s single-thread performance holds up. At 1440p, Ultra is also viable at 120.9 FPS if you prefer maximum visual quality over raw refresh rate, but High is the better overall trade-off. The 4K Ultra setting should be avoided unless you are willing to accept sub-70 FPS, as the game’s fast movement and verticality benefit from higher frame rates. In summary, the measured rows indicate that this combo excels at 1440p High, with 4K High as a strong secondary option for those prioritizing resolution over refresh rate.
