Doom

The Intel Core i7-14700KF and AMD Radeon RX 6650 XT combination sits at rank 1105 out of 1681 tested combos in Doom, placing it in the lower-middle tier of the database. This pairing is capable of delivering playable frame rates across most settings, but the data clearly shows a system where the GPU is the primary bottleneck, especially at higher resolutions and quality presets. The combo’s position reflects a hardware pairing that is well-suited for 1080p competitive play but struggles to maintain high refresh rates at 4K.

How This Combo Ranks

The combo’s rank of 1105 out of 1681 tested configurations places it in the 34th percentile of all tested systems in Doom. This is a middling result, indicating that while the system is far from the bottom of the pack, it is also nowhere near the top tier of performance. The ranking is heavily influenced by the GPU’s position in the broader market; the Radeon RX 6650 XT holds a percentile ranking of 72 among all GPUs, suggesting it is a solid mid-range part, but not a high-end one. In contrast, the CPU is a much stronger component, with a percentile ranking of 96 among all CPUs, meaning it outperforms the vast majority of processors in the database. The disparity between the CPU’s high percentile and the GPU’s lower one explains why the overall combo rank is not higher. The system’s performance is capped by the graphics card, which cannot fully leverage the processing power of the i7-14700KF in this title. This is a classic example of a CPU that is overqualified for its GPU partner in a game like Doom, which is generally more dependent on graphics throughput than on processor muscle.

CPU Role

The Intel Core i7-14700KF is a 20-core, 28-thread processor with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. It is built on Intel’s 10 nm process and features a 33 MB shared L3 cache. In Doom, this processor provides an enormous amount of headroom. The game, released in 2016, is not particularly demanding on modern high-core-count CPUs, and the i7-14700KF’s benchmark scores reflect its immense capability. For instance, it scores 44,557 points in Cinebench R23 multi-core and 6,290 points in single-core, which are very strong numbers. Its average benchmark score of 70,104 places it in the 96th percentile of all CPUs, and its nearest rivals include the Intel Core i7-14700K, which scores a nearly identical 70,074, and the AMD Ryzen 9 9950X at 70,420. The data suggests that the CPU is never a limiting factor in this pairing. Even in the most demanding scenarios, the processor is likely idling or operating well below its maximum potential. The 125W TDP and support for DDR4 and DDR5 memory further indicate that this is a high-end desktop part designed for heavy workloads, not for a 2016 FPS title. Therefore, the CPU’s role is to provide a stable, unconstrained platform, ensuring that all performance limits are dictated by the GPU.

GPU Role

The AMD Radeon RX 6650 XT is the definitive performance ceiling for this combo. It is built on the RDNA 2.0 architecture with a 7 nm process and features 8 GB of GDDR6 memory on a 128-bit bus, delivering 280.3 GB/s of bandwidth. The GPU has a base clock of 2055 MHz, a game clock of 2410 MHz, and a boost clock of 2635 MHz. Its benchmark scores are respectable for a mid-range card; it scores 17,166 in Passmark G3D and 93,769 in Geekbench Vulkan, placing it in the 72nd percentile of all GPUs. Its nearest rivals are the AMD Radeon RX 6800M with an average score of 29,011, and the AMD Radeon RX 470 at 28,996, showing that it sits in a tightly contested performance band. In Doom, the GPU’s 8 GB VRAM is sufficient for most settings, but the card’s overall compute power is what determines the frame rates. The data shows a clear pattern: as resolution and settings increase, the GPU’s workload grows, and the frame rates drop accordingly. The GPU is the component that must be managed to achieve smoother gameplay, and its performance characteristics define the system’s capabilities in this title.

Measured FPS Breakdown

The measured FPS data reveals a wide range of performance depending on resolution and settings. At 1920x1080, the system delivers high frame rates across the board. With Low settings, the average FPS is 197.6, which drops to 176.7 on Medium, 145.8 on High, and 117.8 on Ultra. These numbers indicate that at 1080p, the combo is well-suited for high-refresh-rate monitors, even at the highest quality preset. Moving to 2560x1440, performance remains strong but begins to show the GPU’s limitations. Low settings yield an average of 126.5 FPS, Medium drops to 115.1, High to 96.5, and Ultra falls to 78.9. These figures are still playable, and even the Ultra preset at 1440p maintains an average above 60 FPS, which is a solid result. At 3840x2160, the system struggles to maintain high frame rates. Low settings produce an average of 72.9 FPS, which is acceptable, but Medium drops to 58.7, High to 51, and Ultra falls to 40.5. This shows that the RX 6650 XT is not designed for 4K gaming, especially at higher quality presets, where the frame rates dip below the 60 FPS threshold that many players consider the minimum for smooth gameplay.

Resolution Scaling

The scaling from 1080p to 4K clearly illustrates the GPU-bound nature of this system. At 1080p with Ultra settings, the system achieves 117.8 FPS. When moving to 1440p Ultra, the frame rate drops to 78.9 FPS, a 33% decrease. Further scaling to 4K Ultra results in 40.5 FPS, which is a 66% decrease from the 1080p figure. This steep drop-off is a classic sign of a GPU that is running out of pixel-pushing power. The CPU’s performance does not scale negatively with resolution; in fact, higher resolutions typically reduce CPU load relative to the GPU. Therefore, the data indicates that the i7-14700KF has ample headroom even at 1080p, and the bottleneck is almost entirely the RX 6650 XT. The pattern is consistent across all settings. For example, at High settings, the system goes from 145.8 FPS at 1080p to 96.5 FPS at 1440p, and then to 51 FPS at 4K. The relative performance gap between 1080p and 4K grows as settings increase, from a 63% drop at Low (197.6 to 72.9) to a 66% drop at Ultra (117.8 to 40.5). This suggests that the GPU’s memory bandwidth and compute units become more strained at higher resolutions, and the lack of a significant FPS boost from lowering settings at 4K (from 72.9 FPS at Low to 40.5 FPS at Ultra) confirms that the card is maxed out. For users targeting 4K, the data suggests that only Low settings are viable for a smooth experience, while 1440p and 1080p offer much more flexibility.
