GPU Role

The NVIDIA GeForce RTX 3070 Ti is the dominant force in this pairing, built on the Ampere architecture with a GA104 chip fabricated on Samsung's 8 nm process. Its specifications are formidable: 6,144 shading units, 192 texture mapping units, and 96 raster output pipelines. The GPU also carries 48 RT cores and 192 Tensor cores, though these are less relevant for Doom's traditional rasterization workload. The core clocks are set at a base of 1575 MHz with a boost up to 1770 MHz, providing a solid foundation for the high frame rates observed.

The memory subsystem is a critical component for high-resolution gaming. The 8 GB of GDDR6X memory runs at an effective speed of 19 Gbps across a 256-bit bus, yielding a substantial 608.3 GB/s of bandwidth. The data reveals this is more than adequate for Doom, as even the most demanding 4K Ultra preset maintains an average of 55.7 FPS. The GPU's raw compute capability is rated at 21.75 TFLOPS for FP32 operations, which translates directly into the shader performance needed for the game's fast-paced action.

The GPU's role becomes increasingly pronounced as resolution scales up. At 1080p, the GPU is often not the limiting factor, as evidenced by the high frame rates exceeding 200 FPS on most settings. However, at 4K, the pixel throughput demand grows exponentially, and the RTX 3070 Ti's performance becomes the primary constraint. The data shows a clear trend: moving from 1080p High (199.5 FPS) to 4K High (67.9 FPS) represents a 66% reduction in frame rate, which aligns with the GPU's workload increasing by roughly four times the pixel count. The GPU's percentile ranking of 74 among all GPUs, with an average benchmark score of 30,849, places it as a capable mid-to-high-end performer that excels in this title's optimized engine.

CPU Role

The AMD Ryzen 7 5800X3D serves as the central processing unit, built on the Zen 3 architecture (codenamed "Vermeer") using TSMC's 7 nm process. This desktop processor features 8 cores and 16 threads, with a base clock of 3.40 GHz that can boost up to 4.50 GHz. Its defining characteristic is the massive 96 MB of shared L3 cache, which is a key asset for gaming workloads that frequently reuse data. The CPU's memory bandwidth is rated at 51.2 GB/s via dual-channel DDR4 support, with a 105 W TDP.

For Doom, the CPU's performance is strong enough to avoid becoming a bottleneck at lower resolutions. The synthetic benchmarks show a robust single-thread score of 884 in 3DMark and a multi-thread score of 7,285 in the max-threads test. More relevantly, the Cinebench R23 multi-core score of 24,063 and single-core score of 3,397 indicate that both single and multi-threaded workloads are handled with ease. The processor's average benchmark score of 26,574 places it in the 83rd percentile of all CPUs, with nearest rivals including the AMD EPYC 8024P (0.1% faster) and the Intel Core i9-11900K (0.1% faster).

The CPU's influence is most visible in the 1080p results, where frame rates are high enough that the processor's ability to feed the GPU becomes critical. At 1080p Low, the system achieves 270 FPS, and the scaling from Low to High (270 to 199.5 FPS) shows a 26% drop, which is driven by both GPU and CPU load. However, the CPU's 8 cores and 16 threads are well-suited for Doom's engine, which is known for efficient multi-threading. The 96 MB L3 cache likely helps maintain consistent frame pacing, as the data shows no anomalous dips in the average FPS figures across different settings.

How This Combo Ranks

In the grand scheme of tested systems for Doom, this configuration holds the 675th position out of 1,681 total combos. This ranking places it just above the 40th percentile, meaning it outperforms more than 60% of all systems tested in this game. The rank is a composite measure that reflects both the CPU and GPU's ability to handle the game's demands at various settings and resolutions.

The ranking is somewhat modest given the hardware's individual capabilities, which points to Doom's excellent optimization and scalability. The game's id Tech engine is efficient enough that even mid-range hardware can achieve high frame rates, compressing the performance gap between top-tier and mid-tier systems. The RTX 3070 Ti's 74th percentile GPU ranking and the 5800X3D's 83rd percentile CPU ranking suggest that the combo should perform better than its 675th overall rank indicates. This discrepancy highlights that Doom is less demanding than many other titles, allowing a wider range of systems to achieve similar performance levels.

When comparing to other combos, the data implies that the GPU is the more significant contributor to the final ranking. The system's performance at 1440p and 4K scales closely with the GPU's capabilities, while the CPU's strong cache hierarchy ensures it isn't left behind. The 675th rank is not a reflection of weakness but rather a signal of the game's accessibility; many systems with less powerful components can still push respectable frame rates, narrowing the field.

Resolution Scaling

The measured FPS data across 1080p, 1440p, and 4K reveals a textbook example of resolution scaling, with the GPU becoming the primary bottleneck as pixel count increases. At 1080p, the system is largely CPU-bound, especially on lower settings. The average frame rate on Low settings is 270 FPS, which drops to 238.6 FPS on Medium and 199.5 FPS on High, before settling at 166.4 FPS on Ultra. This progression shows a 38% reduction from Low to Ultra at 1080p, driven by increasing GPU load that begins to shift the bottleneck.

Moving to 1440p, the GPU's role expands. The frame rates are 176.3 FPS (Low), 156 FPS (Medium), 130.5 FPS (High), and 104 FPS (Ultra). The delta between Low and Ultra is now 41%, slightly larger than at 1080p, indicating that the GPU is taking on more of the performance burden. At 4K, the GPU is unequivocally the limiting component. The averages are 93 FPS (Low), 81.9 FPS (Medium), 67.9 FPS (High), and 55.7 FPS (Ultra). The drop from 1080p Low to 4K Low is 65.6%, and from 1080p Ultra to 4K Ultra is 66.5%, showing consistent scaling behavior.

The most telling comparison is the FPS drop from 1080p to 4K at the same settings. For Low settings, the drop is from 270 to 93 FPS, a 65.6% reduction. For High settings, it's from 199.5 to 67.9 FPS, a 66% reduction. This consistency suggests that the CPU is not introducing any variable bottleneck at higher resolutions; the GPU's pixel throughput is the sole limiting factor. The data also shows that the RTX 3070 Ti can maintain playable frame rates at 4K on all settings, with the lowest observed average being 55.7 FPS on Ultra, which is still above the 50 FPS threshold for smooth gameplay. The scaling indicates that for 4K gaming, the 8 GB VRAM and 608.3 GB/s bandwidth are sufficient, and the GPU's 21.75 TFLOPS compute is the key performance driver.
