# Doom — AMD Ryzen 5 5600F + AMD Radeon RX 6750 XT

This combo delivers a thoroughly playable Doom experience across all tested resolutions, with the AMD Ryzen 5 5600F pairing with the AMD Radeon RX 6750 XT to produce frame rates that range from a 4K Ultra average of 51 FPS all the way up to a 1080p Low average of 242 FPS. The measured data shows a system that scales predictably with resolution and settings, with the GPU becoming the dominant limiting factor at higher resolutions while the CPU's six Zen 3 cores provide ample headroom at 1080p.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial and clearly indicates a GPU-bound scenario at higher resolutions. Moving from 1920x1080 to 3840x2160 at High settings, the average frame rate falls from 178 FPS to 62 FPS — a 65% reduction. This steep decline is characteristic of a system where the Radeon RX 6750 XT's rendering throughput is the primary constraint as pixel count quadruples.

At Low settings, the scaling is even more dramatic in absolute terms: 242 FPS at 1080p drops to 85 FPS at 4K, a 65% decrease that mirrors the High preset's relative falloff. The consistency of this percentage across settings suggests that resolution scaling is uniform regardless of visual complexity, pointing to a fixed GPU bottleneck rather than any CPU limitation emerging at lower settings.

The Medium preset shows a similar pattern, with 210 FPS at 1080p falling to 136 FPS at 1440p and then 74 FPS at 4K. Each step up in resolution costs roughly 45-50% of the remaining performance. The Ultra preset, meanwhile, starts at 145 FPS at 1080p, drops to 94 FPS at 1440p, and bottoms out at 51 FPS at 4K — the only configuration that dips below the 60 FPS threshold.

The gap between 1440p and 4K is consistently larger than the gap between 1080p and 1440p. At High settings, 1440p delivers 115 FPS versus 178 FPS at 1080p (a 35% drop), while 4K's 62 FPS represents a 46% drop from 1440p. This non-linear scaling is typical of a GPU that runs out of fillrate and memory bandwidth as the pixel load grows, with the 432.0 GB/s memory bandwidth and 64 ROPs becoming increasingly strained at 4K.

How This Combo Ranks

This specific combination of the Ryzen 5 5600F and RX 6750 XT ranks 1301 out of 2930 tested combos in Doom, placing it in the 56th percentile of all system pairings evaluated. The rank reflects a mid-field position that is consistent with the hardware's individual standings — the CPU sits in the 85th percentile among all processors, while the GPU's 71st percentile among all graphics cards suggests the pairing is slightly GPU-limited in this title.

The combo rank of 1301 indicates that roughly 44% of tested configurations outperform this pairing in Doom, which is expected given that the RX 6750 XT is positioned as an upper-midrange card. The data shows that this system sits ahead of many lower-tier GPU pairings but trails combinations featuring higher-end RDNA 2 or competing architectures. The rank also factors in the CPU's contribution — the Ryzen 5 5600F's PassMark multithread score of 19236 and single-thread score of 2872 place it competitively, but the GPU's 20700 PassMark G3D score is what ultimately caps performance in this GPU-intensive title.

Relative to its nearest GPU rivals, the RX 6750 XT's average benchmark score of 26011 is only 0.5% ahead of the AMD Radeon R9 M395X and 1.1% ahead of the NVIDIA GeForce RTX 3080 Ti Mobile. These tight margins in synthetic benchmarks do not translate directly to Doom's measured FPS, as the game's engine favors the RX 6750 XT's specific architecture. The CPU's nearest rivals — the Intel Core Ultra 5 225 and AMD Ryzen 5 5500X3D — show virtually identical average scores (36938 and 37018 respectively), confirming that the 5600F is not a performance outlier in either direction.

GPU Role

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with the Navi 22 chip, fabricated on a 7 nm process at TSMC with 17,200 million transistors on a 335 mm² die. The GPU operates at a base clock of 2150 MHz, a boost clock of 2600 MHz, and a game clock of 2495 MHz, with memory running at 2250 MHz (18 Gbps effective) across a 192-bit bus. This configuration yields 432.0 GB/s of memory bandwidth, which proves sufficient for Doom's texture-heavy environments at 1440p but becomes a limiting factor at 4K Ultra.

The 12 GB of GDDR6 memory is more than adequate for Doom — the game was released in 2016 and does not approach this capacity at any tested setting. The 2560 shading units, 160 TMUs, and 64 ROPs deliver 416.0 GTexel/s texture fillrate and 166.4 GPixel/s pixel fillrate. In Doom's fast-paced combat scenarios, the pixel fillrate is the more critical metric, and the data shows that 4K Ultra's 51 FPS average is where the ROP throughput begins to buckle.

The GPU's FP32 performance of 13.31 TFLOPS provides the raw compute headroom for Doom's id Tech engine, which scales well with GPU compute resources. The 40 ray accelerators are present but unused in this title, as Doom's original release does not implement ray-traced effects. The card's 71st percentile ranking among all GPUs and its PassMark G3D score of 20700 place it solidly in the upper-middle tier, and the measured FPS confirms it can handle 1440p High at 115 FPS and 1080p Ultra at 145 FPS without breaking a sweat.

Measured FPS Breakdown

At 1920x1080, the RX 6750 XT delivers exceptional performance across all settings. The Low preset averages 242 FPS, with the Medium preset at 210 FPS showing a minimum of 179 FPS and maximum of 242 FPS. High settings average 178 FPS, while Ultra drops to 145 FPS. At this resolution, even the most demanding preset maintains frame rates far above the refresh rate of typical monitors, and the data suggests the CPU is not limiting performance — the 5600F's six cores and 12 threads provide sufficient headroom.

Moving to 2560x1440, the averages remain high but show the GPU starting to work harder. Low delivers 156 FPS, Medium drops to 136 FPS (minimum 116, maximum 157), High averages 115 FPS, and Ultra falls to 94 FPS. The delta between Low and Ultra at 1440p is 62 FPS, compared to 97 FPS at 1080p, indicating that the GPU's headroom is being consumed by the additional pixels rather than by visual quality settings.

At 3840x2160, the GPU becomes the clear bottleneck. Low settings average 85 FPS, Medium drops to 74 FPS (minimum 63, maximum 85), High averages 62 FPS, and Ultra bottoms out at 51 FPS. The gap between Low and Ultra at 4K narrows to 34 FPS, showing that pixel count dominates over settings. The Medium preset's minimum of 63 FPS is the only sub-4K data point that approaches the 60 FPS threshold, while Ultra at 4K falls below it entirely.

CPU Role

The AMD Ryzen 5 5600F is a six-core, 12-thread processor based on the Zen 3 architecture (Vermeer codename), manufactured on a 7 nm TSMC process. It runs at a base clock of 3.00 GHz with a boost clock of 4.00 GHz, and its 32 MB of shared L3 cache provides fast access to Doom's frequently accessed game data. The CPU's 65 W TDP reflects its efficiency, and its PassMark single-thread score of 2872 indicates strong per-core performance that benefits Doom's largely single-threaded render thread.

The CPU's benchmark results show a PassMark multithread score of 19236 and a floating-point math score of 34548, with integer math at 59339. These numbers place the 5600F in the 85th percentile among all CPUs, and its nearest rivals include the Intel Core Ultra 5 225 (with an average score of 36938, essentially identical to the 5600F's 36945) and the AMD Ryzen 5 5500X3D (37018, 0.2% higher). The data indicates that the 5600F is well-matched to the RX 6750 XT for Doom, as the measured FPS at 1080p Low (242 FPS) demonstrates the CPU can feed the GPU far beyond what the card can render.

In Doom, the CPU's role is most apparent at lower resolutions where the GPU has spare capacity. The 1080p Low result of 242 FPS represents a ceiling imposed by the CPU's ability to issue draw calls and update game state, while the 4K results show the GPU taking over as the limiting factor. The 12 threads handle Doom's background simulation tasks without issue, and the 3.00 GHz base clock with 4.00 GHz boost provides adequate responsiveness for the game's twitch-based combat.

Settings Recommendations

For 4K gaming, the Medium preset at 74 FPS average (with a 63 FPS minimum) offers the best balance of visual quality and performance. The High preset's 62 FPS average is technically playable but leaves less margin for demanding scenes, while Ultra's 51 FPS falls below the standard smoothness threshold. Low at 85 FPS is viable for competitive play, but Medium provides substantially better visuals for only an 11 FPS cost.

At 1440p, the Ultra preset at 94 FPS is the recommended choice for visual fidelity, as it remains well above 60 FPS while delivering the full suite of effects. For players prioritizing maximum frame rates, Low at 156 FPS or Medium at 136 FPS are excellent options, with High at 115 FPS striking a middle ground. The 1440p Ultra result of 94 FPS shows this resolution is the sweet spot for the RX 6750 XT.

At 1080p, the choice depends on the display's refresh rate. For 144 Hz panels, Ultra at 145 FPS is ideal. For 240 Hz displays, the Low preset's 242 FPS average (with a 242 FPS maximum at Medium) fully saturates the refresh rate. High at 178 FPS is a strong middle option that maintains high visual quality while staying above 165 Hz. The data shows that 1080p Ultra is the most demanding preset the card handles comfortably at this resolution.
