# AMD Ryzen 7 3700X + NVIDIA GeForce RTX 5080 in Doom

This pairing brings together an 8-core, 16-thread AMD processor built on the 3000-series architecture with a flagship-class NVIDIA GPU from the GeForce 50-series. The data shows a system that delivers extremely high frame rates across all tested resolutions in Doom, though the scaling patterns reveal interesting dynamics about where the bottleneck shifts as settings and resolution change.

CPU Role

The AMD Ryzen 7 3700X operates with 8 cores and 16 threads, running at a base clock of 3.60 GHz and a boost clock of 4.40 GHz. This Zen 2 architecture chip uses the AMD Socket AM4 platform and supports DDR4 memory with dual-channel configuration. Its Cinebench R23 multi-core score of 19087 and single-core score of 2694 place it in the 85th percentile among all CPUs, indicating solid mid-range performance relative to the broader market.

Benchmark results show this processor sits remarkably close to several rivals in aggregate performance. The Intel Core i5-12600 scores 28654, a delta of -0.1% from the Ryzen 7 3700X's average benchmark score of 28631. Similarly, the Intel Core i5-12600H achieves 28666, also -0.1% behind, while the AMD Ryzen 5 5600XT trails by just 0.1% at 28591. This cluster of near-identical scores suggests the CPU is not a differentiator in this system—its performance envelope is well understood and competitive within its class.

In Doom, the CPU's role becomes more apparent at lower resolutions and settings. The 1080p Low preset reaches 278.4 FPS, which is the highest measured value in the entire dataset. At such extreme frame rates, the processor's single-thread performance—evidenced by its Cinebench R23 single-core score of 2694—becomes the limiting factor. The game engine must feed the GPU with draw calls and game logic updates fast enough to sustain those rates, and the 3.60 GHz base clock with 4.40 GHz boost provides sufficient headroom for this workload.

GPU Role

The NVIDIA GeForce RTX 5080 brings substantial graphics horsepower with 16 GB of GDDR7 memory on a 256-bit bus, delivering 960.0 GB/s of bandwidth. Its Blackwell 2.0 architecture includes 10752 shading units, 336 texture mapping units, and 112 ROPs. The GPU operates at a base clock of 2295 MHz with a boost clock of 2617 MHz, and memory runs at 1875 MHz with 30 Gbps effective speed. These specifications translate to a pixel rate of 293.1 GPixel/s and a texture rate of 879.3 GTexel/s.

The GPU's 3DMark Steel Nomad DX12 score of 8637 and Passmark G3D score of 36565 place it in the 89th percentile among all GPUs. Its average benchmark score of 59188 positions it near the Intel Arc A570M, which scores 58239 with a delta of 1.6%, and the Intel Arc Pro A60 at 60326 with a -1.9% delta. These comparisons highlight that while the RTX 5080 is a high-end card, its nearest rivals in the benchmark database are not necessarily direct competitors in real-world gaming scenarios.

In Doom, the GPU's influence dominates at higher resolutions and quality settings. The 4K Ultra preset drops to 87.4 FPS, the lowest measured value, showing that the card's rendering workload at 3840x2160 with maximum settings exceeds what even this powerful GPU can sustain at high frame rates. The 16 GB VRAM capacity proves sufficient even at 4K, as no memory-related performance anomalies appear in the data.

Resolution Scaling

Examining the frame rate progression from 1080p to 4K reveals clear bottleneck patterns. At High settings, the system delivers 248.9 FPS at 1920x1080, 201.4 FPS at 2560x1440, and 111.2 FPS at 3840x2160. The drop from 1440p to 4K represents a 44.8% reduction in frame rate, while the drop from 1080p to 1440p is 19.1%. This accelerating decline as resolution increases strongly indicates the GPU becomes progressively more the limiting component at higher pixel counts.

The Low settings tell a similar story with different magnitudes. From 278.4 FPS at 1080p to 240.9 FPS at 1440p (a 13.5% drop) and then to 148.7 FPS at 4K (a 38.3% drop from 1440p), the pattern holds. The CPU's ability to maintain high frame rates at lower resolutions is evident—the 1080p Low result is only 13.5% higher than 1440p Low, suggesting the processor is nearing its practical limit for this game engine.

Ultra settings show the most dramatic scaling penalty. At 1080p Ultra, the system achieves 234 FPS, which drops 30.5% to 162.6 FPS at 1440p, and then another 46.2% to 87.4 FPS at 4K. This 62.7% total reduction from 1080p to 4K at Ultra settings confirms that the RTX 5080's rendering capabilities are the primary constraint at higher quality levels, with the CPU contributing less to the overall performance picture as resolution increases.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low achieves 278.4 FPS, Medium reaches 263.6 FPS, High hits 248.9 FPS, and Ultra bottoms out at 234 FPS. The spread between Low and Ultra is 44.4 FPS, representing a 16% performance range. This relatively narrow gap suggests the CPU is holding back the GPU at this resolution, as the graphics card would likely deliver larger differences between quality presets if it were the limiting factor.

Moving to 2560x1440, the performance hierarchy shifts. Low still leads at 240.9 FPS, followed by Medium at 228.9 FPS, High at 201.4 FPS, and Ultra at 162.6 FPS. The gap between Low and Ultra widens to 78.3 FPS, or 32.5%, showing the GPU's increasing influence. The Medium setting performs notably well here, coming within 5% of Low while presumably offering better visual quality.

At 3840x2160, the GPU's workload becomes dominant. Low delivers 148.7 FPS, Medium 128.1 FPS, High 111.2 FPS, and Ultra 87.4 FPS. The spread between Low and Ultra reaches 61.3 FPS, or 41.2%, indicating the graphics card is now the clear bottleneck. Even at Low settings, 4K resolution demands significant GPU resources, and the RTX 5080's 16 GB of GDDR7 memory and 960.0 GB/s bandwidth are put to substantial use.

How This Combo Ranks

The combination of AMD Ryzen 7 3700X and NVIDIA GeForce RTX 5080 ranks 245th out of 1681 tested combos in Doom, placing it in the top 14.6% of all system configurations in the database. This ranking reflects the substantial GPU capability rather than the CPU's modest performance, as the processor's percentile standing of 85th among all CPUs is lower than the GPU's 89th percentile.

The rank position suggests this combo outperforms the majority of tested systems in Doom, but the specific pairing creates an interesting imbalance. The RTX 5080's nearest rivals in aggregate benchmarks—the Intel Arc A570M and AMD Radeon Pro W5500X—are not typically associated with high-end gaming performance, yet the 5080's raw power still pushes this combo into the upper tier. The Ryzen 7 3700X, while not a top-tier gaming CPU by current standards, provides enough processing capability to avoid severely limiting the GPU at most settings.

Settings Recommendations

For 1080p gaming, the Ultra preset at 234 FPS delivers the best visual experience while still maintaining frame rates far above display refresh rate capabilities. The data shows the CPU limits performance at this resolution, so choosing Ultra settings costs only 16% of the Low preset's frame rate while providing maximum visual quality. Players with high-refresh-rate 1080p displays will find Ultra the optimal choice.

At 1440p, the Medium preset at 228.9 FPS offers the best balance. It sits within 5% of Low's 240.9 FPS while presumably providing better visual fidelity. High at 201.4 FPS remains viable for those prioritizing quality, but Ultra's 162.6 FPS represents a significant 29% drop from Medium for diminishing visual returns. The 1440p Medium configuration appears to be the sweet spot for this combination.

For 4K gaming, High settings at 111.2 FPS provide the best overall experience. Ultra drops to 87.4 FPS, which remains playable but approaches the threshold where frame pacing becomes noticeable. Medium at 128.1 FPS offers higher performance but sacrifices visual quality. The High preset at 4K leverages the GPU's capabilities effectively while maintaining frame rates above 100 FPS, making it the recommended choice for immersive gameplay.
