GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture with a Navi 23 chip manufactured on a 7 nm process. Its memory subsystem consists of 8 GB of GDDR6 on a 128-bit bus, yielding a bandwidth of 224.0 GB/s. The GPU's base clock is 1626 MHz, with a game clock of 2044 MHz and a boost clock of 2491 MHz. The memory operates at 1750 MHz, effectively 14 Gbps.

In Doom, the GPU's role becomes increasingly dominant as resolution scales upward. At 1920x1080, the combo achieves 178.8 FPS on Low settings, but at 3840x2160 the same settings yield only 60.2 FPS — a drop of 118.6 FPS. This indicates that the RX 6600's 8 GB frame buffer and 224.0 GB/s bandwidth are sufficient for lower resolutions but become limiting factors at 4K. The data suggests that at 3840x2160, the GPU is the primary bottleneck, as the CPU's substantial compute resources cannot compensate for the GPU's reduced throughput at higher pixel counts.

The GPU's pixel rate of 159.4 GPixel/s and texture rate of 279.0 GTexel/s provide context for its behavior in Doom. At 2560x1440, the combo maintains 112.7 FPS on Low, but Ultra settings cut that down to 65.5 FPS. This pattern highlights that the RX 6600's raw fill rates are adequate for mid-range resolutions but degrade sharply with increased graphical complexity. The GPU's FP32 performance of 8.928 TFLOPS supports these observations, as the card struggles to maintain high frame rates when both resolution and settings are pushed simultaneously.

CPU Role

The Intel Core Ultra 7 265K features 20 cores and 20 threads, with a base clock of 3.90 GHz and a boost clock of 5.50 GHz. It comes from the Arrow Lake architecture, built on a 3 nm process at TSMC, with 30 MB of shared L3 cache and 3 MB of L2 cache per core. The CPU's memory bandwidth is rated at 102.4 GB/s over a dual-channel DDR5 interface.

In Doom, the CPU's role is most apparent at lower resolutions where the GPU is not fully saturated. At 1920x1080, the combo scales from 108.1 FPS on Ultra to 178.8 FPS on Low, a difference of 70.7 FPS. This scaling indicates that the CPU can feed the GPU efficiently at high frame rates, leveraging its 20 cores and 5.50 GHz boost clock to handle the game's draw calls and physics without becoming a limiting factor. The CPU's single-thread performance, evidenced by a Cinebench R23 single-core score of 7060, supports this capability.

At 3840x2160, however, the CPU's influence diminishes. The difference between Low (60.2 FPS) and Ultra (38.4 FPS) is 21.8 FPS, which is smaller in absolute terms than at 1080p. This suggests that at 4K, the GPU's workload dominates, and the CPU's high core count and clock speeds are underutilized. The CPU's multi-threaded strength, reflected in a Cinebench R23 multi-core score of 50009, provides headroom for other tasks but does not translate to proportionally higher frame rates in this GPU-bound scenario.

How This Combo Ranks

The Intel Core Ultra 7 265K and AMD Radeon RX 6600 combination ranks 1354 out of 1681 tested combos in Doom. This places it in the bottom 20% of all pairings, which is notable given the CPU's high performance percentile of 97. The discrepancy arises because the GPU's 69th percentile ranking drags down the overall combo performance in a game that is heavily GPU-dependent at higher settings.

The CPU's nearest rivals include the Intel Core Ultra 7 265KF (deltaPct -0.2%), Intel Core i9-14900KF (-0.2%), Intel Core i9-14900K (-0.9%), and AMD EPYC 7413 (-1.2%). These small deltas indicate that the CPU is competitive with top-tier alternatives, but none of these comparisons change the fact that the combo's rank is primarily constrained by the GPU. The GPU's nearest rivals — AMD Radeon 890M (0%), AMD Radeon RX 580 2048SP (-0.2%), AMD Radeon RX 6700M (0.2%), and NVIDIA GeForce RTX 3060 Ti (0.5%) — show that the RX 6600 is positioned near other mid-range cards, but none of these alternatives appear in the measured FPS data for this combo.

In practice, the combo rank reflects a pairing where the CPU vastly outperforms the GPU in synthetic benchmarks, yet the game's results show that this imbalance does not yield top-tier frame rates. The data indicates that users would see better returns from a more balanced pairing, but the current combination still delivers playable performance at most settings below 4K.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend on the target resolution and frame rate. At 1920x1080, all settings exceed 100 FPS, with Low at 178.8 FPS, Medium at 152.2 FPS, High at 131.6 FPS, and Ultra at 108.1 FPS. For smooth 1080p gameplay at high refresh rates, Medium or High settings provide a strong balance between visual quality and performance, as both stay above 130 FPS.

At 2560x1440, the combo achieves 112.7 FPS on Low, 96.6 on Medium, 84.2 on High, and 65.5 on Ultra. For a 60 Hz display, Ultra settings are viable, but for 144 Hz monitors, Medium or Low is necessary to maintain high frame rates. The data suggests that High at 1440p is a reasonable choice for users prioritizing visual fidelity without dropping below 80 FPS.

At 3840x2160, only Low settings break the 60 FPS threshold, hitting 60.2 FPS. Medium falls to 55.5, High to 43.9, and Ultra to 38.4. For 4K gaming, Low settings are the only viable option for acceptable performance, and even then, the frame rate is marginal. Users targeting 4K should consider lowering resolution or accepting reduced graphical quality.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings produce an average of 178.8 FPS, Medium reaches 152.2 FPS, High achieves 131.6 FPS, and Ultra settles at 108.1 FPS. The spread from Low to Ultra is 70.7 FPS, showing that the game scales significantly with settings at this resolution.

At 2560x1440, performance drops noticeably. Low averages 112.7 FPS, Medium 96.6 FPS, High 84.2 FPS, and Ultra 65.5 FPS. The gap between Low and Ultra here is 47.2 FPS, which is narrower than at 1080p, indicating that the GPU is becoming more of a limiting factor.

At 3840x2160, the combo struggles to maintain high frame rates. Low averages 60.2 FPS, Medium 55.5 FPS, High 43.9 FPS, and Ultra 38.4 FPS. The difference between Low and Ultra is just 21.8 FPS, demonstrating that the GPU's compute and memory bandwidth are saturated at this resolution, with diminishing returns from settings adjustments. The data shows a clear pattern: as resolution increases, the relative impact of settings decreases, and the GPU's 8 GB VRAM and 224.0 GB/s bandwidth become the primary constraints.
