Doom

Resolution Scaling

The measured frame rates for Doom with the Intel Core i7-14700F and AMD Radeon RX 7800 XT show a clear and predictable scaling pattern as resolution increases. At 1920x1080 with High settings, the combo produces an average of 209 FPS. Moving to 2560x1440 at High settings, the average drops to 135 FPS, a decrease of 74 FPS or roughly 35%. At 3840x2160 with High settings, the average falls further to 73 FPS, which represents a 46% reduction from the 1440p result and a 65% reduction from the 1080p result.

This scaling behavior is characteristic of a system where the GPU becomes progressively more dominant as the pixel count rises. The 1080p to 1440p transition shows a steeper relative drop than the 1440p to 4K transition when expressed as a percentage of the previous resolution’s performance, suggesting that at 1080p the CPU is still contributing meaningfully to frame generation. The fact that the 4K High result of 73 FPS remains well above playable thresholds indicates that the RX 7800 XT has sufficient headroom even at the highest common resolution.

Comparing the Low preset across resolutions provides additional insight. At 1080p Low, the average is 284 FPS; at 1440p Low it is 184 FPS; and at 4K Low it is 99 FPS. The 1080p Low figure is exceptionally high, pointing to a scenario where the CPU’s 20 cores and 28 threads are capable of feeding frames far faster than most displays can show. The 4K Low result of 99 FPS is notable because it exceeds the 4K High result by 26 FPS, demonstrating that the GPU’s workload scaling with settings is substantial. The limiting component at 4K is clearly the GPU, as lowering settings from High to Low yields a 26 FPS improvement, while the same settings change at 1080p yields only a 75 FPS improvement in absolute terms but a much larger relative jump from 209 to 284 FPS.

CPU Role

The Intel Core i7-14700F is a 20-core, 28-thread processor from the Core 14th Gen series, built on Intel’s Raptor Lake architecture with a 10 nm process node. Its base clock is 2.10 GHz, with a boost clock of 5.40 GHz. The processor has 33 MB of shared L3 cache, 2 MB of L2 cache per core, and 80 KB of L1 cache per core. It supports both DDR4 and DDR5 memory in dual-channel configuration, and it offers PCIe Gen 5 with 16 lanes for the CPU.

In Doom, the CPU’s role is most evident at 1080p, where the average FPS at Low settings reaches 284. This is a benchmark result that places the i7-14700F in the 91st percentile among all CPUs based on its average benchmark score of 53,620. Its nearest rivals in synthetic benchmarks include the Intel Xeon 6505P with a score of 53,701 (0.2% higher), the Intel Xeon Phi 7290 with 53,469 (0.3% lower), the AMD Ryzen 9 7900X with 53,288 (0.6% lower), and the AMD EPYC 7313P with 53,206 (0.8% lower). These rival comparisons are based on average benchmark scores, not Doom-specific results, but they contextualize the CPU’s general capability.

The boost clock of 5.40 GHz is likely a key factor in the game’s high frame rates at lower resolutions. Doom, being a fast-paced FPS, benefits from high single-thread performance, and the Cinebench R23 single-core score of 4,958 points confirms strong single-thread throughput. The multi-core score of 35,122 points in the same test indicates that the processor can handle heavy multi-threaded workloads, though the game itself may not fully utilize all 28 threads. The measured data shows that at 1080p Low, the frame rate is 284 FPS, which is higher than any other resolution or preset combination, suggesting that the CPU is not the bottleneck at that setting. However, at 4K Ultra, the average drops to 60 FPS, indicating that the GPU is the limiting factor there, as the CPU has ample headroom.

GPU Role

The AMD Radeon RX 7800 XT is a RDNA 3.0 architecture GPU with the Navi 32 chip, manufactured on a 5 nm process at TSMC. It features 16 GB of GDDR6 memory on a 256-bit bus, providing a bandwidth of 624.1 GB/s. The GPU’s base clock is 1295 MHz, with a boost clock of 2430 MHz and a game clock of 2124 MHz. Memory operates at 2438 MHz, which translates to 19.5 Gbps effective. The GPU has 3,840 shading units, 240 texture mapping units, and 96 raster output units, along with 60 ray tracing cores. Its FP32 performance is rated at 37.32 TFLOPS.

In Doom, the GPU’s role becomes increasingly pronounced as resolution rises. At 4K, the average FPS ranges from 60 at Ultra settings to 99 at Low settings. The difference between Ultra and Low at 4K is 39 FPS, which is a substantial performance swing. At 1440p, the range is from 110 FPS at Ultra to 184 FPS at Low, a 74 FPS difference. At 1080p, the range is from 171 FPS at Ultra to 284 FPS at Low, a 113 FPS difference. This pattern shows that the GPU’s workload scales significantly with both resolution and settings, but the absolute impact of settings changes is largest at lower resolutions where the GPU is less saturated.

The GPU’s percentile ranking among all GPUs is 51, with an average benchmark score of 11,627. Its nearest rivals in the database include the NVIDIA GeForce GTX 1660 with a score of 11,680 (0.5% higher), the AMD Radeon Pro 5500M with 11,528 (0.9% lower), the NVIDIA Tesla K20c with 11,479 (1.3% lower), and the AMD Radeon RX 6500 XT with 11,842 (1.8% higher). These comparisons are based on aggregate benchmarks, not Doom specifically, but they suggest that the RX 7800 XT sits in a mid-range position relative to all GPUs. In Doom, however, the 4K High result of 73 FPS demonstrates that the GPU is well-suited for high-resolution gaming in this title.

The 16 GB VRAM capacity is more than sufficient for Doom’s requirements, as the game does not exhibit signs of memory capacity limiting at 4K Ultra. The bandwidth of 624.1 GB/s supports the high frame rates observed, particularly at 1440p and 1080p where the GPU can push beyond 100 FPS even at Ultra settings.

How This Combo Ranks

The combination of the Intel Core i7-14700F and AMD Radeon RX 7800 XT ranks 1,238 out of 3,712 tested combos in Doom, placing it in the top third of all configurations. This rank of 1,238 out of 3,712 means that approximately 67% of tested combos perform worse in this game, while 33% perform better. The data is measured, not estimated, which adds confidence to the ranking.

This rank is notably higher than the GPU’s individual percentile ranking of 51, which suggests that the CPU-GPU pairing is well-balanced for Doom. The CPU’s strong single-thread performance, as evidenced by its 91st percentile ranking among all CPUs, complements the GPU’s mid-range position. In a game like Doom, which rewards high frame rates, the CPU’s ability to feed frames quickly at lower resolutions helps the combo achieve better-than-average overall results.

The rank of 1,238 also indicates that there are many combos with more powerful GPUs that outperform this setup, particularly at 4K where the GPU becomes the bottleneck. However, for the vast majority of gaming scenarios at 1080p and 1440p, this combo delivers frame rates that are near or above the refresh rates of most high-end monitors. At 1080p High, the 209 FPS average is well above competitive gaming standards, and at 1440p High, the 135 FPS average remains smooth. The 4K Ultra result of 60 FPS is exactly at the threshold for standard 60 Hz displays, making it a viable option for 4K gaming with reduced settings.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and desired frame rate. At 1920x1080, all presets deliver playable frame rates, with Ultra averaging 171 FPS, High at 209 FPS, Medium at 247 FPS, and Low at 284 FPS. For 1080p gaming, the High preset offers a strong balance between visual quality and performance, with 209 FPS providing a comfortable margin above 144 Hz displays. The Medium preset at 247 FPS is suitable for 240 Hz monitors, though the visual trade-off from High to Medium is typically minimal in Doom.

At 2560x1440, the High preset produces 135 FPS, which is ideal for 144 Hz displays. The Ultra preset at 110 FPS is also viable for 120 Hz monitors, offering higher visual fidelity. The Medium preset at 160 FPS exceeds the refresh rate of most 1440p 144 Hz panels, making it a good choice for those prioritizing maximum smoothness. The Low preset at 184 FPS is unnecessary for most users, as the visual quality reduction is not worth the additional frame rate.

At 3840x2160, the Ultra preset averages 60 FPS, which is playable but leaves no headroom for frame drops. The High preset at 73 FPS is the recommended choice for 4K gaming, as it provides a 13 FPS improvement over Ultra while likely maintaining most visual quality. The Medium preset at 87 FPS offers an even larger margin, with a min FPS of 74 and a max FPS of 100, making it suitable for 4K displays with variable refresh rates. The Low preset at 99 FPS is the best option for 4K gaming on high refresh rate panels, though the visual compromise is significant.

For the best overall experience, the High preset at 1440p is recommended, as it balances the 135 FPS average with good visual quality. For 4K, High is the sweet spot at 73 FPS, providing a playable experience without excessive graphical compromises.
