Doom

The pairing of AMD’s Ryzen 7 7800X3D with NVIDIA’s GeForce GTX 1070 in Doom presents a classic study in system balance, where a modern flagship processor is mated to a mid-range graphics card from an older generation. The measured frame rates across resolutions and settings reveal a scenario where the GPU consistently dictates performance, while the CPU’s substantial headroom remains largely untapped. This analysis breaks down the data to show exactly where the bottleneck lies and what the resulting frame rates mean for gameplay.

Resolution Scaling

The frame rate progression from 1920x1080 to 3840x2160 clearly demonstrates that the GTX 1070 is the primary performance limiter in this configuration. At 1080p with Low settings, the combo achieves 159.3 FPS, but this drops to 100.8 FPS at 1440p and further to 53.2 FPS at 4K. This scaling pattern—a 47% reduction from 1080p to 1440p and another 47% reduction from 1440p to 4K—indicates that the GPU is working near its absolute limits as pixel count increases. The CPU’s vast computational capacity, evidenced by its 8 cores and 16 threads, is not the limiting factor here; if it were, the frame rates would remain more consistent across resolutions.

The data suggests that at 1080p, the GTX 1070 is still able to push frames at a rate that approaches the refresh rate of many monitors, but the margin for error is thin. Moving to 1440p, the average FPS at High settings falls to 75.6, which is still playable but begins to show the GPU’s age. The most telling drop occurs at 4K, where even Low settings only yield 53.2 FPS, and Ultra settings collapse to 32 FPS. This steep decline confirms that the GTX 1070’s 8 GB of GDDR5 memory and 256-bit bus width are insufficient for the demands of 4K rendering, making the resolution scaling a direct function of the GPU’s pixel throughput.

GPU Role

The GTX 1070’s specifications—a base clock of 1506 MHz and boost clock of 1683 MHz—are modest by modern standards, but its performance in Doom is still respectable at lower resolutions. The GPU’s 1920 shading units and 64 ROPs provide a solid foundation for the game’s Vulkan-based engine, which is known for its efficiency. However, the measured results indicate that the card’s 256.3 GB/s memory bandwidth becomes a bottleneck at higher settings. At 4K Ultra, the frame rate drops to 32 FPS, a 40% reduction from the 53.2 FPS seen at 4K Low, showing how texture and shader complexity saturate the memory subsystem.

The GPU’s percentile ranking of 51 among all tested GPUs places it squarely in the middle of the pack, and its average benchmark score of 12331 reflects a card that is neither obsolete nor competitive with modern mid-range offerings. In Doom, the GTX 1070’s performance ceiling is evident at 1440p Ultra, where it manages 59.2 FPS—just above the 60 FPS target but with no headroom for demanding scenes. The card’s 8 GB VRAM is adequate for 1080p and 1440p, but the data shows that at 4K, the memory capacity and bandwidth are insufficient to maintain playable frame rates, particularly on Ultra settings.

CPU Role

In stark contrast to the GPU, the AMD Ryzen 7 7800X3D is an absolute powerhouse that is barely challenged by Doom. With 8 cores based on the Zen 4 architecture and a boost clock of 5.00 GHz, the CPU’s performance metrics are exceptional: a Cinebench R23 multicore score of 29149 and a single-core score of 4115. The processor’s 96 MB of shared L3 cache is particularly beneficial for gaming, as it reduces memory latency and improves data access patterns. However, in this specific pairing, the CPU’s role is merely to feed the GTX 1070 with enough data to keep it busy, and the frame rates show that it does so without breaking a sweat.

At 1080p Low, the combo achieves 159.3 FPS, which is likely near the point where the CPU could become a factor, but the GPU still holds the reins. The CPU’s single-thread performance, as measured by a Geekbench single-core score of 2725, is more than sufficient for Doom’s engine, which does not heavily utilize multi-threading. The 3DMark scores further illustrate this: the processor’s 2-thread score of 1887 and 4-thread score of 3684 show strong scaling, but the game does not require such resources. The Ryzen 7 7800X3D is simply overqualified for this task, and its performance headroom would only be visible with a more powerful GPU.

How This Combo Ranks

Among the 1681 tested combinations in the database, this specific pairing of the Ryzen 7 7800X3D and GTX 1070 ranks 1426th. This position, in the bottom 15% of all combos, is a clear indication that the GPU is dragging down the overall potential of the system. The CPU alone ranks in the 87th percentile among all CPUs, while the GPU sits in the 51st percentile, creating a massive imbalance. The combo’s ranking is almost entirely determined by the GPU, as the CPU’s power is wasted in this context.

The CPU’s nearest rivals in synthetic benchmarks—the Intel Core i7-12700F with a deltaPct of 0.1% and the AMD Ryzen 9 5980HX with a deltaPct of 0.3%—demonstrate that the 7800X3D is in elite company. However, when paired with the GTX 1070, these CPU differences are imperceptible in Doom’s frame rates. The data shows that to move this combo significantly up the rankings, a GPU upgrade would be mandatory, as the current graphics card is the sole constraint on performance.

Measured FPS Breakdown

At 1920x1080, the resolution where the GTX 1070 is most comfortable, the frame rates are respectable across all settings. The Low preset yields 159.3 FPS, Medium drops to 136.8 FPS, High comes in at 114.1 FPS, and Ultra brings the average down to 95.7 FPS. These numbers show a smooth degradation as settings increase, with the delta between Low and Ultra being 63.6 FPS. At this resolution, the combo is playable even on Ultra, though the 95.7 FPS average leaves little room for drops in intense combat.

Moving to 2560x1440, the GTX 1070 begins to show its limitations. The Low preset achieves 100.8 FPS, which is still smooth, but Medium falls to 86.4 FPS, High to 75.6 FPS, and Ultra to 59.2 FPS. The gap between Low and Ultra here is 41.6 FPS, and the Ultra result is only marginally above the 60 FPS threshold. For competitive play, the High preset at 75.6 FPS offers the best balance, but the data indicates that the GPU is working hard at this resolution.

At 3840x2160, the GTX 1070’s performance collapses. The Low preset manages 53.2 FPS, Medium drops to 50.4 FPS, High falls to 41.8 FPS, and Ultra plummets to 32 FPS. None of these averages reach the 60 FPS target, and the Ultra result is barely playable. The scaling from Low to Ultra at 4K is only 21.2 FPS, showing that the GPU is completely bottlenecked by its memory bandwidth and compute capabilities. This resolution is effectively unusable for this combo, and the data strongly suggests staying at 1080p or 1440p for a playable experience.

FAQ

*Q: What is the best resolution to play Doom with this combo?*

A: Based on the measured data, 1920x1080 offers the most consistent performance, with all settings averaging above 95 FPS. At 2560x1440, only Low and Medium settings provide smooth frame rates above 86 FPS, while Ultra drops to 59.2 FPS. 3840x2160 is not recommended, as even Low settings only reach 53.2 FPS.

Q: How does the GTX 1070’s 8 GB VRAM affect 4K performance?

A: The 8 GB VRAM is insufficient for 4K in Doom. The measured data shows a significant drop at 3840x2160, with Ultra settings yielding only 32 FPS. The 256.3 GB/s memory bandwidth is also a limiting factor, as higher settings at 4K saturate the memory subsystem.

Q: Is the Ryzen 7 7800X3D the bottleneck in this system?

A: No. The CPU’s benchmark scores, such as a Cinebench R23 multicore score of 29149, are exceptionally high. The frame rate scaling from 1080p to 4K clearly shows the GPU is the limiting component, not the CPU.

Q: What is the difference in performance between Low and Ultra settings at 1440p?

A: At 2560x1440, the Low preset achieves 100.8 FPS, while Ultra drops to 59.2 FPS. This is a 41.6 FPS difference, indicating that the GTX 1070 has limited headroom for high-quality settings at this resolution.

Q: How does this combo’s rank of 1426 out of 1681 compare to the CPU’s individual rank?

A: The CPU ranks in the 87th percentile among all CPUs, while the combo ranks 1426th out of 1681. This discrepancy highlights that the GPU is severely limiting the system’s overall performance potential.

Q: Can this combo maintain 60 FPS at 1080p on Ultra settings?

A: Yes. The measured average FPS at 1920x1080 on Ultra is 95.7, which is well above the 60 FPS target. However, this leaves less headroom for demanding scenes, so some frame drops may occur during intense combat.
