Doom

The Intel Core i7-14700F and AMD Radeon RX 6750 XT combination delivers a compelling 1080p and 1440p experience in Doom, but the data clearly shows where the GPU starts to struggle. This pairing is a solid high-refresh-rate option for the classic FPS, though 4K Ultra should be avoided.

Resolution Scaling

The measured FPS data reveals a predictable yet steep performance curve as resolution increases. At 1080p with High settings, the combo produces 178.5 FPS average. Dropping to 1440p High reduces that to 115.5 FPS, a significant 35.3% decrease. Moving up to 4K High yields 62.6 FPS, which represents another 45.8% drop from 1440p. This scaling pattern indicates that the Radeon RX 6750 XT is the primary limiting factor at higher resolutions, as the performance loss aligns with the increased pixel count rather than any CPU bottleneck.

The data shows the gap between resolutions narrows at lower settings. At Low, 1080p delivers 239.8 FPS, 1440p produces 153.9 FPS, and 4K still manages 85 FPS. The percentage drop from 1080p to 4K at Low is 64.6%, compared to a 64.9% drop at High settings. This consistency suggests the GPU is heavily taxed across all settings, though the absolute numbers remain playable at 4K Low. Notably, the jump from 1440p to 4K is consistently larger than 1080p to 1440p, reinforcing that the RX 6750 XT hits a wall near the 4K boundary.

GPU Role

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with a Navi 22 chip fabricated on a 7 nm process from TSMC. It carries 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The GPU clocks run at 2150 MHz base and 2600 MHz boost, with a game clock of 2495 MHz. These specifications translate to 2560 shading units, 160 texture mapping units, and 64 raster operation units, producing 13.31 TFLOPS of FP32 performance.

In Doom, this hardware configuration shows its strengths and limitations clearly. The 12 GB VRAM is sufficient for the game's textures at all tested settings, as evidenced by the consistent performance scaling without any anomalies that would suggest memory capacity issues. The 432.0 GB/s bandwidth appears adequate for 1080p and 1440p, but the 4K results indicate the memory interface becomes a constraint when pushing higher pixel counts. The GPU's percentile ranking against all GPUs is 79, placing it above the majority but not in the top tier. Its nearest rival, the AMD Radeon RX 5600M, scores 0.2% higher in average benchmarks, while the NVIDIA GeForce RTX 3080 sits 1.3% higher, showing this card operates in a competitive mid-range band.

Settings Recommendations

For the best balance of visual quality and frame rate, the data points to Medium settings as the sweet spot for this combination. At 1080p Medium, the combo produces 210.6 FPS, which is 31.7% higher than High settings and only 12.2% lower than Low. At 1440p Medium, the 135.7 FPS average remains well above the 120 FPS threshold that many players target for smooth gameplay, while High drops to 115.5 FPS. For 4K, Medium yields 75.4 FPS, which is playable but not ideal for fast-paced action; High sits at 62.6 FPS, and Ultra falls to 50.6 FPS.

Players with high refresh rate monitors should prioritize 1080p Medium or High. The 1080p High result of 178.5 FPS exceeds most 144Hz displays, while 1440p Medium at 135.7 FPS is suitable for 144Hz panels but not 165Hz or higher. The Ultra preset should be avoided at all resolutions if frame rate consistency matters, as even 1080p Ultra drops to 144.6 FPS, which is 31.3% below Medium. For 4K usage, Low settings at 85 FPS provide the only comfortable margin above 60 FPS, making it the practical choice for 4K displays.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings produce 239.8 FPS average, Medium achieves 210.6 FPS, High reaches 178.5 FPS, and Ultra bottoms out at 144.6 FPS. The spread from Low to Ultra is 95.2 FPS, representing a 39.7% performance penalty for maximum visual quality. All 1080p results exceed 144 FPS, making this resolution ideal for competitive play.

Moving to 2560x1440, the numbers remain strong but show the GPU working harder. Low settings generate 153.9 FPS, Medium delivers 135.7 FPS, High produces 115.5 FPS, and Ultra falls to 93.1 FPS. The drop from 1080p to 1440p at each setting is substantial: 35.8% for Low, 35.6% for Medium, 35.3% for High, and 35.6% for Ultra. This consistent percentage loss indicates uniform GPU scaling without any unexpected bottlenecks.

At 3840x2160, the limitations become apparent. Low settings yield 85 FPS, Medium drops to 75.4 FPS, High manages 62.6 FPS, and Ultra falls to 50.6 FPS. The 4K results are the only ones where any setting falls below 60 FPS, with Ultra being the sole problematic preset. The scaling from 1440p to 4K shows a 44.8% loss for Low, 44.4% for Medium, 45.8% for High, and 45.7% for Ultra, indicating a consistent performance ceiling.

How This Combo Ranks

In the benchmark database, this Intel Core i7-14700F plus AMD Radeon RX 6750 XT combination ranks 843rd out of 1681 tested combos for Doom. This places it in the upper half of all configurations, specifically at the 50.1st percentile. The ranking reflects a balanced system that outperforms many lower-end pairings but falls short of top-tier combinations that feature more powerful GPUs.

The CPU component of this pair is notably strong. The Intel Core i7-14700F ranks in the 94th percentile against all CPUs, with an average benchmark score of 54097. Its nearest rivals include the AMD Ryzen 9 9900X, which scores 0.6% higher, and the AMD Ryzen 9 9900X3D at 1.1% higher. This places the CPU near the top of the performance hierarchy, suggesting it is not the limiting factor in this combo's 843rd rank. The GPU, ranking in the 79th percentile, is the more modest component and likely drives the overall combo position.

CPU Role

The Intel Core i7-14700F provides substantial processing headroom for Doom. It features 20 cores and 28 threads, with a base clock of 2.10 GHz and a boost clock of 5.40 GHz. The Raptor Lake architecture uses a 10 nm process from Intel, and the chip includes 80 KB of L1 cache per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. This configuration produces strong synthetic scores, including 35443 in Cinebench R23 multi-core and 5003 in single-core, along with 16571 in Geekbench multi-core.

In Doom, a game originally released in 2016, the CPU requirements are modest. The 14700F's high boost clock of 5.40 GHz ensures excellent single-thread performance, which is critical for game logic and physics. The 28 threads provide ample multi-threading capability, though Doom's engine does not heavily utilize more than a few cores. Benchmark results show the CPU outperforms its nearest rival, the AMD Ryzen 9 9900X, by a negligible 0.6% in average score, confirming it is not a performance bottleneck. The data shows that at 1080p Low, the combo achieves 239.8 FPS, which is close to the practical limit for many displays, indicating the CPU can feed the GPU sufficiently even at lower settings where CPU load is typically higher. The CPU's 65 W TDP and support for both DDR4 and DDR5 memory make it a flexible choice, though its locked multiplier prevents overclocking.
