Doom

The Intel Core i7-14700KF paired with the NVIDIA GeForce RTX 5090 delivers exceptional performance in Doom, with measured frame rates far exceeding the 60 FPS playable threshold across every tested resolution and preset combination. The data reveals a system that is not merely capable but overwhelmingly dominant, with the lowest recorded average frame rate being 99.3 FPS at 4K Ultra settings. This combination of a 20-core, 28-thread Raptor Lake Refresh processor and the 32 GB GDDR7 Blackwell 2.0 GPU creates a platform where the game's engine is never the bottleneck, and the benchmark results consistently show headroom for much higher refresh rates.

Measured FPS Breakdown

The measured FPS data shows a clear and consistent scaling pattern across all three resolutions. At 1920x1080, the system produces extraordinary frame rates, with the Low preset averaging 459.8 FPS, Medium at 402.4 FPS, High at 341.7 FPS, and Ultra at 278.5 FPS. Even the most demanding 1080p setting maintains an average well above 270 FPS, indicating that the RTX 5090's 104.8 TFLOPS of FP32 compute is barely stressed at this resolution. The gap between Low and Ultra at 1080p is 181.3 FPS, which suggests that the graphics settings have a measurable impact, but the absolute floor remains far above any conceivable display refresh rate.

Moving to 2560x1440, the averages remain exceptionally high. The Low preset delivers 297.4 FPS, Medium 258.5 FPS, High 216.8 FPS, and Ultra 180.6 FPS. The delta between Low and Ultra here is 116.8 FPS, which is proportionally similar to the 1080p delta but with a slightly tighter spread, hinting that resolution scaling is beginning to engage the GPU more heavily. At 1440p, even the Ultra preset retains a 120.6 FPS margin above the 60 FPS playable threshold, meaning there is substantial capacity for background tasks or streaming overhead without compromising fluidity.

At 3840x2160, the performance profile shows the expected drop but remains stellar. The Low preset averages 163.8 FPS, Medium 141.3 FPS, High 121.2 FPS, and Ultra 99.3 FPS. The difference between Low and Ultra at 4K is 64.5 FPS, which is the smallest absolute spread across the three resolutions. This compression indicates that at 4K, the GPU is becoming the limiting factor, but the RTX 5090's 1.79 TB/s memory bandwidth and 21760 shading units keep the average well above 90 FPS even at maximum settings. The data shows no min or max FPS values in the measured results, but the average figures alone strongly suggest consistent frame pacing.

CPU and GPU Roles

The benchmark data indicates that the RTX 5090 is the primary performance driver at all three resolutions, but the CPU's role becomes proportionally more important at lower resolutions. At 1920x1080, the difference between Low and Ultra settings is 181.3 FPS, which is the largest absolute spread in the dataset. This large gap suggests that at 1080p, the GPU has enough headroom that the i7-14700KF's single-thread performance, evidenced by its R23 single-core score of 6235, can feed frames fast enough to let the graphics card fully flex its muscle. The CPU's 33 MB of shared L3 cache and 5.60 GHz boost clock likely help maintain high instruction throughput, though the data does not isolate CPU-bound scenarios directly.

At 2560x1440, the spread between Low and Ultra narrows to 116.8 FPS, indicating that the GPU is starting to take on a larger share of the workload. The RTX 5090's pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s are being utilized more fully as the pixel count increases. The 1440p results show the CPU still has influence, but the GPU's raw throughput is becoming the dominant factor. This is consistent with the 4K results, where the Low-to-Ultra spread compresses further to 64.5 FPS, a clear sign that the graphics card is now the bottleneck.

The scaling between resolutions at the same preset reinforces this interpretation. At Ultra settings, moving from 1080p to 1440p drops the average from 278.5 FPS to 180.6 FPS, a 35.2% reduction, and then to 99.3 FPS at 4K, another 45.0% reduction. These drops are far larger than the difference between presets at a fixed resolution, confirming that the GPU's fillrate and bandwidth are the determining factors at higher resolutions. The CPU's 20 cores and 28 threads, with a multithread score of 52425 in PassMark, are more than sufficient to avoid becoming a limiting factor in this game, which is known for its id Tech engine efficiency.

Similar Performance Alternatives

The nearest rivals for the CPU and GPU provide context for what other hardware would deliver similar performance in Doom. For the Intel Core i7-14700KF, the closest competitor in average benchmark score is the AMD Ryzen 7 9700F, which is just 0.2% behind. The AMD Ryzen 9 7940HX is 0.4% ahead, and the AMD Ryzen 9 7950X is 0.9% ahead, meaning these CPUs would likely produce nearly identical frame rates in Doom. The Intel Core Ultra 7 265K is the only rival that trails the i7-14700KF, by 1.0%, which would still be an imperceptible difference in actual gameplay. These deltaPct values are small enough that any of these CPUs would pair equally well with the RTX 5090.

For the GPU, the nearest rivals are more unexpected. The NVIDIA Tesla P100 PCIe 16 GB is 0.3% behind the RTX 5090 in average score, and the Tesla P100 PCIe 12 GB is 0.6% behind, though these are datacenter cards with different driver optimizations. The AMD Radeon RX 6850M XT is 1.1% behind, which is a mobile GPU, and the AMD Radeon Pro Vega 64X is 1.4% ahead of the RTX 5090. In the context of Doom, these rival GPUs would likely produce similar average FPS, though the RTX 5090's 32 GB VRAM and GDDR7 memory give it an advantage in other workloads. The benchmark scores suggest that the difference between these GPUs is within 1.4%, meaning frame rates in Doom would be statistically indistinguishable in most cases.

The Verdict

The verdictByResolution data is unambiguous: this PC can run Doom at every tested resolution and preset with a substantial margin above 60 FPS. At 3840x2160, all four presets—Low, Medium, High, and Ultra—are classified as playable, with the best settings being Ultra at an average of 99.3 FPS. This is 39.3 FPS above the playable threshold, which means even the most demanding 4K configuration leaves significant headroom. At 2560x1440, the same pattern holds, with Ultra averaging 180.6 FPS, which is 120.6 FPS above the threshold. At 1920x1080, the Ultra preset averages 278.5 FPS, a 218.5 FPS margin over the playable threshold.

The data shows no scenario where this combination fails to meet the 60 FPS target, which is expected given the hardware's caliber. The RTX 5090's 92,200 million transistors on a 5 nm process, combined with the i7-14700KF's 125 W TDP and 3.40 GHz base clock, create a system that is overkill for Doom's 2016 engine. The game's release date of 2016-05-12 means it was designed for hardware from that era, so the modern components are providing roughly 5-8x the performance needed. Users with 240 Hz or 360 Hz monitors at 1440p or 1080p will find the frame rates sufficient to take full advantage of high refresh rates.

The comboRankInGame places this specific CPU-GPU pairing at rank 35 out of 3712 tested combinations in Doom. This top 1% placement confirms that the i7-14700KF and RTX 5090 together are among the most capable configurations for this game. The rank of 35 means there are only 34 other hardware combinations that deliver higher average frame rates, and given that the RTX 5090 is one of the fastest consumer GPUs available, those ahead are likely using even more exotic setups. The percentile ranking of the CPU at 94th and GPU at 92nd independently corroborates this top-tier status.

The rank data also implies that the combination is well-balanced for Doom specifically. The 20-core CPU and the 32 GB GPU complement each other without obvious mismatches. The GPU's 92nd percentile is slightly lower than the CPU's 94th percentile, which suggests the graphics card is the limiting factor in achieving even higher ranks, but the difference is minor. For context, the combo rank of 35 out of 3712 means this setup outperforms 99.06% of all tested combinations, which is a strong indicator that users can expect excellent performance in this game.

Best Settings per Resolution

At 3840x2160, the most demanding preset that stays at or above 60 FPS is Ultra, with an average of 99.3 FPS. This is the best possible setting for 4K, and the 39.3 FPS margin above the threshold provides comfortable headroom. At 2560x1440, the Ultra preset also qualifies as the best, averaging 180.6 FPS, which is 120.6 FPS above the threshold. At 1920x1080, the Ultra preset averages 278.5 FPS, a 218.5 FPS margin. In all three cases, the Ultra preset is the most demanding option tested, and it never drops below the playable threshold.

The implication is that users can simply select the maximum quality presets at any resolution without concern. The data shows that even at 4K Ultra, the average FPS of 99.3 is well-suited for 60 Hz displays and capable of driving 120 Hz panels with VRR. For 1440p and 1080p, the Ultra presets deliver frame rates that can fully utilize 240 Hz monitors, though the 459.8 FPS at 1080p Low suggests that competitive players seeking maximum frame rates could push even higher by lowering settings. The measured data only includes average FPS, so min and max frame behavior is unknown, but the high averages imply consistent performance.
