Doom

The Intel Core i3-12100F paired with the NVIDIA GeForce RTX 5070 Ti is a study in asymmetric performance. The GPU is a current-generation powerhouse, while the CPU is a budget quad-core from the 12th Gen. In Doom, this pairing produces a fascinating set of benchmark results that reveal exactly where the bottleneck shifts as resolution and settings change. The data indicates this combo can deliver extremely high frame rates, but the experience is heavily dependent on how the workload is balanced between these two components.

Resolution Scaling

The measured FPS data shows a clear and predictable trend: as resolution increases, average frame rates drop, but the rate of that drop tells the story of which component is the limiting factor. At 1080p High, the combo achieves 278 FPS. Moving to 1440p High, that number falls to 180 FPS, a reduction of approximately 35%. When scaling from 1440p to 4K High, the average drops from 180 FPS to 98 FPS, a further reduction of roughly 46%. This steep decline between 1440p and 4K is the signature of a system transitioning from a CPU-bound state to a GPU-bound state.

The data suggests that at 1080p, the Intel Core i3-12100F is the primary constraint. The GPU is capable of far more work, but the CPU's 4 cores and 8 threads are simply maxed out trying to feed it. This is why the 1080p results are so high—the GPU isn't the bottleneck—and why the jump to 1440p still yields massive frame rates. The RTX 5070 Ti is only beginning to stretch its legs. The transition to 4K, however, shifts the burden almost entirely onto the GPU. The 98 FPS average at 4K High is a strong result, but it represents a massive drop from the 180 FPS at 1440p, indicating that the GPU's rendering workload has finally outpaced the CPU's ability to supply instructions.

Looking at the Low settings across resolutions further clarifies the situation. At 1080p Low, the system hits a wall at 360 FPS. At 1440p Low, it achieves 245 FPS, and at 4K Low, it reaches 133 FPS. The 1080p Low result is telling: it's likely a hard cap or a point where the CPU cannot generate frames any faster. The fact that the 4K Low score (133 FPS) is higher than the 4K High score (98 FPS) confirms that even at 4K, the CPU can still be a limiting factor at lower graphical settings. The frame rate is not just about resolution; the settings themselves also dictate how much work the GPU does per frame, and thus how much it can outpace the CPU. The data shows a system that is CPU-limited at 1080p and 1440p, and only becomes primarily GPU-limited at 4K with higher settings.

CPU Role

The Intel Core i3-12100F is a 4-core, 8-thread processor based on the Alder Lake architecture. Its base clock is 3.30 GHz, and it boosts up to 4.30 GHz. This is a modest specification for modern gaming, but its benchmark scores reveal a strong single-threaded performance. It scores 1674 in Cinebench R23 single-core and 1932 in Geekbench single-core. This single-thread performance is critical for Doom, a game that was designed to run well on a variety of hardware.

In the context of this combo, the CPU's role is to feed frames to the GPU. The benchmark results show that at 1080p, the CPU is the bottleneck. The 360 FPS at Low is likely near the CPU's limit. The CPU's multi-threaded performance is less impressive; it scores 11860 in Cinebench R23 multi-core. This suggests that while it can handle the game's main thread, it may struggle if the game engine tries to use many threads. The data indicates that the i3-12100F provides just enough performance to avoid being a major problem at 1440p, but it is clearly the component holding back the system from achieving the 4K frame rates that the RTX 5070 Ti is capable of.

The CPU's 12 MB of shared L3 cache and support for DDR4 and DDR5 memory are standard for its class. Its performance percentile of 68 compared to all CPUs places it in the upper-mid range of processors, but its nearest rivals are low-power mobile chips like the Intel Core 3 N355 and the Intel Core i7-1250U. This shows that while its average benchmark score is competitive, it lacks the high-core-count muscle of more expensive desktop processors. In Doom, the data suggests the CPU is sufficient, but it's the reason the system doesn't hit triple-digit frame rates at 4K Ultra, where it achieves 80 FPS. The game's performance is ultimately capped by the CPU's ability to process the game's simulation and draw calls.

GPU Role

The NVIDIA GeForce RTX 5070 Ti is a high-end graphics card based on the Blackwell 2.0 architecture. It has 16 GB of GDDR7 memory on a 256-bit bus, providing a bandwidth of 896.0 GB/s. Its boost clock is 2452 MHz. This is a massive amount of memory and bandwidth, which is more than enough for Doom at any resolution. The GPU's compute power is substantial, with 8960 shading units and a FP32 performance of 43.94 TFLOPS.

The benchmark results show that the GPU is not the limiting factor until 4K. At 1080p and 1440p, the GPU is effectively idle-waiting for the CPU to send it data. The high frame rates at these resolutions are a signal of the GPU's efficiency, but they don't test its limits. At 4K, the GPU's role becomes dominant. The scores of 98 FPS at High and 80 FPS at Ultra illustrate the GPU's rendering capability at this demanding resolution. The RTX 5070 Ti has the raw power to push Doom to high frame rates at 4K, but it is held back by the CPU at lower resolutions.

The GPU's 16 GB of VRAM is a significant asset. Doom, even at 4K Ultra, is unlikely to exceed this, so there is no risk of running out of memory. The GPU's 86th percentile ranking among all GPUs and its average benchmark score of 49957 place it in the top tier of graphics cards. Its nearest rivals in terms of average score are older cards like the AMD Radeon RX 6900 XT and the AMD Radeon RX 6800 XT, which shows that the 5070 Ti is a significant upgrade in raw performance. In this specific pairing, the GPU's potential is only fully realized at 4K, where its massive compute and memory bandwidth are the primary drivers of the final frame rate.

FAQ

Q: Is the Intel Core i3-12100F going to bottleneck the RTX 5070 Ti in Doom?

A: Yes, the data strongly suggests a CPU bottleneck at 1080p and 1440p. At 1080p High, the system achieves 278 FPS, and at 1080p Low, it hits 360 FPS. These are very high numbers, but the difference between them shows the CPU is the limiting factor. The GPU is capable of more, but the CPU cannot feed it faster. At 4K, the GPU becomes the primary bottleneck, as indicated by the larger frame rate drops with increased settings.

Q: What is the best resolution for this combo to get high frame rates?

A: The data shows that 1440p offers the best balance. At 1440p High, the system averages 180 FPS, which is excellent for a high-refresh-rate monitor. At 4K, the frame rate drops to 98 FPS on High, which is still playable but not as high. The 1440p resolution allows the GPU to stretch its legs while the CPU can still keep up.

Q: How much of a performance difference is there between Low and Ultra settings at 4K?

A: The difference is significant. At 4K Low, the system averages 133 FPS. At 4K Ultra, the average drops to 80 FPS. This is a 40% reduction in frame rate for the higher quality settings. The data shows that the GPU is heavily taxed by the Ultra preset at 4K.

Q: Is the RTX 5070 Ti overkill for this CPU?

A: In this specific game, the data suggests it is overkill at 1080p and 1440p. The system is clearly CPU-limited at those resolutions. However, at 4K, the GPU is fully utilized, and its power is necessary to achieve the 98 FPS High and 80 FPS Ultra scores. The GPU is not overkill if you plan to play at 4K.

Q: What is the combo's rank compared to all other tested combos for this game?

A: The combo ranks at 389 out of 3712 tested combinations. This places it in the top 10.5% of all combos tested for Doom. This is a strong ranking, but it is not near the top, which would require a more powerful CPU to match the GPU's potential.

Q: Are the frame rates stable, or are there big dips?

A: The data includes min and max FPS for Medium settings. At 4K Medium, the average is 115 FPS, with a minimum of 98 and a maximum of 133. At 1440p Medium, the average is 213 FPS, with a minimum of 181 and a maximum of 245. This suggests frame times are relatively stable, with the minimum FPS staying close to the average.

How This Combo Ranks

The combo of the Intel Core i3-12100F and NVIDIA GeForce RTX 5070 Ti ranks 389th out of 3712 tested combinations for Doom. This is a strong result, placing the system in the top 10.5% of all tested configurations. This ranking is a reflection of the GPU's high-end performance, but it also shows the CPU's limitations. A system with a more powerful CPU would likely rank higher, as the RTX 5070 Ti has the potential to score even higher in this game.

The data indicates that this ranking is primarily achieved through the GPU's prowess. The 4K results, where the CPU is less of a factor, are impressive. The ranking suggests that for a user who is willing to play at 4K, this is a very capable system. However, for users targeting 1080p or 1440p with very high refresh rate monitors, the CPU will prevent the system from reaching its full potential, and the rank might be lower than what the GPU alone could achieve. The rank of 389 is a compromise; it is the result of a high-end GPU being paired with a mid-range CPU.

The percentile of the CPU (68th) and GPU (86th) individually highlight the mismatch. The GPU is in the top 14% of all GPUs, while the CPU is in the top 32%. This discrepancy is what brings the combo's overall rank down from what a top-tier CPU would achieve. The benchmark results show that the system is balanced at 4K, which is where the ranking is likely most favorable.

Settings Recommendations

The measured data provides a clear path for the best settings at each resolution. The goal is to maximize frame rate while maintaining a stable experience, and the data shows where the CPU and GPU are each the limiting factor.

For 1080p, the CPU is the clear bottleneck. The data shows a 360 FPS average at Low, a 329 FPS at Medium, and 278 FPS at High. The jump from Low to Medium is only a 9% drop, while the jump from Medium to High is a 15% drop. Since the CPU is the limit, using the High preset is the best choice. It offers a significant visual upgrade over Medium for a relatively small performance cost, and the 278 FPS average is still exceptionally high. The Ultra preset at 227 FPS is also viable, but the performance cost is steeper.

For 1440p, the system is still CPU-bound, but the GPU is starting to work harder. The data shows 245 FPS at Low, 213 FPS at Medium, and 180 FPS at High. The High preset is again the sweet spot. The 180 FPS average is ideal for a high refresh rate 1440p monitor. The Ultra preset at 147 FPS is also a good option if you prefer maximum quality, but the High preset offers a better balance of visual quality and performance.

For 4K, the GPU becomes the primary bottleneck. The data shows 133 FPS at Low, 115 FPS at Medium, 98 FPS at High, and 80 FPS at Ultra. Here, the High preset is the best recommendation. The 98 FPS average is a solid score for 4K gaming and is much closer to 100 FPS than the 80 FPS of Ultra. The drop from High to Ultra is 18%, which is a significant reduction for the visual gain. The Medium preset at 115 FPS is also a good choice if you prefer a higher frame rate, but High offers a better balance of quality and performance. The Low preset is not recommended, as the visual hit is severe and the frame rate gain over Medium is only 16%. The data shows that the High preset at 4K is the optimal configuration for this combo.
