Doom

The Intel Core i7-14700F paired with the AMD Radeon RX 580 is a study in imbalance. The CPU sits in the 94th percentile of all processors, while the GPU lands in the 53rd. In Doom, that gap shows: the combo ranks 1540th out of 1681 tested combinations, a result that places it near the bottom of the field. The data indicates a GPU-bound system where the RX 580's 8GB frame buffer and 256-bit bus are the limiting factors, not the 20-core Raptor Lake chip. At 1080p the pair can deliver playable frame rates, but at 1440p and 4K the GPU's age becomes decisive.

CPU Role

The Intel Core i7-14700F is a 20-core, 28-thread processor based on Raptor Lake-R, built on Intel's 10 nm process. It runs at a 2.10 GHz base clock and boosts to 5.40 GHz, with 33 MB of shared L3 cache. Its launch MSRP is $359. In synthetic benchmarks, the chip posts a Cinebench R23 multi-core score of 35443 and a single-core score of 5003, while Geekbench returns 16571 multi-core and 2711 single-core. Passmark's multithread test yields 41765, and the single-thread score is 4261. These numbers place the CPU in the 94th percentile of all processors, with an average benchmark score of 54097.

Against its nearest rivals, the i7-14700F trails the AMD Ryzen 9 9900X by 0.6% (9900X avg score 54450) and the Ryzen 9 9900X3D by 1.1% (54681). It leads the Intel Xeon Phi 7290 by 1.2% (53469) and the AMD EPYC 7313P by 1.7% (53206). For a game like Doom, which is a fast-paced FPS from 2016, single-thread performance matters more than raw core count. The i7-14700F's 5.40 GHz boost and strong single-core Cinebench score of 5003 suggest it can feed frames quickly when the GPU is not the bottleneck. However, the measured FPS data shows that the GPU is almost always the limiting factor, so the CPU's headroom is largely unused in this configuration.

GPU Role

The AMD Radeon RX 580 is a Polaris 20 part on GlobalFoundries' 14 nm process, with 5,700 million transistors and a die size of 232 mm². It features 2304 shading units, 144 TMUs, and 32 ROPs, with a base clock of 1257 MHz and a boost clock of 1340 MHz. Memory is 8 GB of GDDR5 on a 256-bit bus, running at 2000 MHz (8 Gbps effective) for 256.0 GB/s of bandwidth. The card's FP32 throughput is 6.175 TFLOPS, and its TDP is 185 W. Its launch MSRP is 229 USD. In the benchmark database, the RX 580 holds a 53rd percentile ranking among all GPUs, with an average benchmark score of 13559.

The nearest rivals show how tightly grouped this GPU is: the NVIDIA GeForce GTX 570 scores 13564 (delta 0%), the GTX 950 scores 13549 (RX 580 is 0.1% ahead), the AMD Radeon Pro 455 scores 13416 (RX 580 is 1.1% ahead), and the NVIDIA P106-090 scores 13716 (RX 580 is 1.1% behind). In Doom, the RX 580's 8GB VRAM is sufficient for the game's textures, but its raw compute power is not. The measured FPS data shows that at 4K, even Low settings only produce 38.5 fps, and Ultra drops to 24.1 fps. At 1440p, Low hits 67.9 fps, but Ultra falls to 40.3 fps. Only at 1080p does the card consistently exceed 60 fps across all settings, with Ultra at 62.5 fps. The GPU's 256-bit bus and 256 GB/s bandwidth are adequate for 1080p, but the 6.175 TFLOPS of FP32 performance is simply not enough for higher resolutions in this title.

FAQ

Q: What is the best resolution for this combo in Doom?

A: 1080p. The measured FPS shows 105 fps on Low, 90.2 on Medium, 76.6 on High, and 62.5 on Ultra — all above 60 fps. At 1440p, only Low (67.9) and Medium (59.3) approach playable levels, while 4K never exceeds 38.5 fps.

Q: Is this combo suitable for 4K gaming in Doom?

A: No. Even at Low settings, the average frame rate is 38.5 fps, and Ultra drops to 24.1 fps. The RX 580's compute and memory bandwidth are insufficient for 4K in this title.

Q: How does the i7-14700F compare to the Ryzen 9 9900X?

A: The i7-14700F trails the Ryzen 9 9900X by 0.6% in average benchmark score (54097 vs 54450). It also sits 1.1% behind the Ryzen 9 9900X3D, but leads the Xeon Phi 7290 by 1.2% and the EPYC 7313P by 1.7%.

Q: How does the RX 580 compare to the GTX 950?

A: The RX 580 is 0.1% ahead of the GTX 950 in average benchmark score (13559 vs 13549). It is also 1.1% ahead of the Radeon Pro 455 and 1.1% behind the P106-090.

Q: What is the bottleneck in this system?

A: The GPU. The CPU is in the 94th percentile, while the GPU is in the 53rd. The measured FPS scales with resolution and settings in a way that tracks GPU load, not CPU capability. At 1080p Low, the combo hits 105 fps, but at 4K Ultra it falls to 24.1 fps — a pattern consistent with a GPU-limited configuration.

Q: Which settings are playable at 1440p?

A: Low and Medium yield 67.9 and 59.3 fps respectively. High (49.1) and Ultra (40.3) fall below 60 fps, so a 60 Hz display would require Low or Medium.

Measured FPS Breakdown

The measured FPS data covers three resolutions and four quality presets. At 3840x2160, the combo averages 23.5 fps on High, 38.5 on Low, 32.4 on Medium, and 24.1 on Ultra. None of these are playable for a fast-paced FPS. At 2560x1440, the results improve: High 49.1, Low 67.9, Medium 59.3, Ultra 40.3. Only Low and Medium exceed 60 fps, and even then only marginally. At 1920x1080, the picture is much better: High 76.6, Low 105, Medium 90.2, Ultra 62.5. All presets clear 60 fps, with Low nearly doubling the 4K Ultra result.

The scaling is consistent with a GPU-bound system. Dropping from 4K to 1080p at the same settings yields a 3.3x increase in frame rate (e.g., High from 23.5 to 76.6). Lowering settings at a fixed resolution also produces predictable gains: at 1080p, moving from Ultra to Low increases the average from 62.5 to 105 fps, a 68% improvement. The RX 580's 8GB VRAM is not a limiting factor at any tested setting, as Doom's texture requirements are modest, but the GPU's compute throughput caps performance at higher resolutions.

How This Combo Ranks

In the benchmark database, this specific combination of Intel Core i7-14700F and AMD Radeon RX 580 ranks 1540th out of 1681 tested combos for Doom. That places it in the bottom 8.4% of all configurations — only 141 combos are worse. The rank reflects the GPU's modest standing: the RX 580 is in the 53rd percentile of all GPUs, while the CPU is in the 94th. The data shows that the combo's performance is almost entirely dictated by the GPU, as the CPU's high single-thread and multi-thread scores do not translate into higher frame rates once the GPU is saturated.

The rank also implies that most other tested combos — even those with weaker CPUs but stronger GPUs — achieve better results in Doom. The game's 2016 release means it is not particularly demanding on modern CPUs, so the i7-14700F's 20 cores and 5.40 GHz boost are overkill for this title. The RX 580, meanwhile, is a mid-range card from 2017 that was never designed for 4K gaming. The measured FPS confirms this: at 1080p, the combo is playable, but at 1440p and above, it falls short of the 60 fps target that most gamers expect. For anyone considering this pairing, the data suggests that the CPU is a long-term investment, but the GPU will need an upgrade to unlock the system's potential in Doom and similar titles.
