Doom

The AMD Ryzen 7 7800X3D and NVIDIA GeForce RTX 4070 combination delivers exceptional performance in Doom, placing this pairing in the 443rd position out of 1,681 tested combos. This places the configuration in the top quartile of all tested systems, a result driven by the CPU’s high single-thread throughput and the GPU’s substantial rasterization power. The data shows a system capable of exploiting Doom’s Vulkan-based engine to its fullest, producing frame rates that exceed the refresh rates of most high-end displays at standard resolutions.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 7800X3D is an 8-core, 16-thread processor based on the Zen 4 architecture, operating at a base clock of 4.20 GHz and a boost clock of 5.00 GHz. Its large 96 MB shared L3 cache is a defining characteristic, though for a title like Doom—which is not heavily cache-sensitive in the same way as simulation or strategy games—the raw clock speed and per-core efficiency prove more relevant. The processor’s single-thread performance, as measured by a 3DMark single-thread score of 959, is the key attribute for this game. Doom’s engine is known for scaling well with multiple threads, but it still places a premium on the primary game thread.

The CPU’s multi-threaded capabilities are also robust, with a 3DMark max-threads score of 7,967 and a Cinebench R23 multi-core score of 29,149. This headroom ensures that background tasks or game logic threads do not bottleneck the frame rendering pipeline. The 7800X3D’s average benchmark score of 31,580 places it just 0.1% ahead of the Intel Core i7-12700F, which scores 31,543, and 0.3% ahead of the AMD Ryzen 9 5980HX at 31,495. This tight grouping indicates that in purely CPU-bound scenarios, the 7800X3D provides a marginal edge over its closest rivals, but the real differentiation in this combo comes from the pairing with the RTX 4070.

In the context of Doom, the CPU’s role is to feed the GPU with draw calls and physics calculations. The benchmark results show that at lower resolutions, the CPU’s capability becomes the limiting factor, as the GPU can render frames faster than the CPU can issue them. At 1080p with Low settings, the average frame rate reaches 316.6 FPS, a figure that approaches the practical limits of the CPU’s game-thread performance. This is a classic sign of a CPU-bound scenario, where further reductions in graphical load yield diminishing returns on frame rate.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The frame rate scaling across resolutions reveals a clear shift in the bottleneck from the CPU to the GPU. At 1920x1080 with High settings, the combo produces 232.2 FPS. Moving to 2560x1440 with the same settings, the frame rate drops to 148.5 FPS, a reduction of 36%. This is a substantial drop, but the frame rate remains high, indicating that the CPU is still capable of keeping up with the GPU’s output. However, when moving to 3840x2160 with High settings, the frame rate falls to 80.4 FPS, a further 46% reduction from the 1440p result.

This scaling pattern is characteristic of a system where the GPU becomes the primary limiting factor at higher resolutions. The pixel count increases by a factor of 2.25 from 1440p to 4K, and the frame rate drops by roughly half, which is consistent with a GPU-bound scenario. The RTX 4070’s 12 GB of GDDR6X memory and 504.2 GB/s of bandwidth are sufficient for 4K textures, but the raw shading power begins to show its limits. The CPU, with its high single-thread score, is not the constraint here; the data indicates that at 4K, the RTX 4070 is working near its maximum capacity.

The scaling from Low to Ultra settings at each resolution further confirms this. At 1080p, the frame rate drops from 316.6 FPS on Low to 187.1 FPS on Ultra, a 41% reduction. At 1440p, the drop is from 206 FPS on Low to 121.5 FPS on Ultra, a 41% reduction as well. At 4K, the drop is from 113.1 FPS on Low to 63.9 FPS on Ultra, a 43% reduction. The consistency of these percentage drops across resolutions suggests that the GPU’s workload scales predictably with settings, and the CPU is not introducing a variable bottleneck that would cause the drops to widen at lower resolutions.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured frame rates provide a comprehensive view of the combo’s performance across nine distinct configurations. At 1920x1080, the lowest tested resolution, the combo delivers exceptional performance. With Low settings, the average frame rate is 316.6 FPS. Medium settings yield 272.7 FPS, High settings produce 232.2 FPS, and Ultra settings still maintain a very high 187.1 FPS. All of these figures are well above the 144 Hz refresh rate common on high-end monitors, making the system capable of fully saturating such displays.

At 2560x1440, the performance remains impressive. Low settings produce an average of 206 FPS, Medium settings yield 175.4 FPS, High settings deliver 148.5 FPS, and Ultra settings maintain 121.5 FPS. These numbers indicate that the combo is still CPU-bound at this resolution, as the frame rates are high enough to suggest the GPU is not being pushed to its absolute limit. The 1440p Ultra result of 121.5 FPS is particularly notable, as it provides a smooth experience on high-refresh-rate 1440p monitors.

At 3840x2160, the GPU becomes the clear bottleneck. Low settings produce an average of 113.1 FPS, Medium settings yield 93.6 FPS, High settings deliver 80.4 FPS, and Ultra settings produce 63.9 FPS. The 4K Low result shows that even with minimal graphical load, the GPU cannot exceed 113.1 FPS, which is a significant drop from the 206 FPS seen at 1440p Low. This demonstrates the rendering load of 4K on the RTX 4070. The 4K Ultra result of 63.9 FPS is still playable, but it is the only configuration in the dataset that dips below the 80 FPS mark, indicating that for 4K gaming, the user must make a choice between resolution and graphical fidelity.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combo’s rank of 443 out of 1,681 tested combinations places it within the top 26% of all systems tested in Doom. This is a strong result, though it is not in the upper echelon of the absolute highest-performing rigs. The ranking reflects the balance between the Ryzen 7 7800X3D and the RTX 4070. The CPU’s performance, as indicated by its 87th percentile ranking among all CPUs, is top-tier. The GPU’s performance, ranked in the 81st percentile among all GPUs, is also strong, but it is not at the same elite level as the CPU.

This disparity is visible in the benchmark results. The CPU’s nearest rivals—the Intel Core i7-12700F, AMD Ryzen 9 5980HX, AMD Ryzen 7 8700G, and AMD Ryzen 7 7745HX—all have average scores within 0.6% of the 7800X3D. This suggests that the CPU is not a differentiator in the ranking; any of these processors would produce similar results in a CPU-bound scenario. The GPU’s nearest rivals, however, include the AMD Radeon RX Vega 56, which scores 0.6% higher than the RTX 4070, and the NVIDIA GeForce MX570 A, which scores 1.9% higher. The presence of these rivals indicates that the RTX 4070 is not the fastest GPU in its class, and the ranking is likely influenced by the GPU’s performance at 4K, where it struggles to maintain high frame rates.

The data shows that the combo’s rank is primarily driven by the RTX 4070’s capabilities. In a game like Doom, which is well-optimized and can run on a wide range of hardware, the GPU’s rasterization performance is the key factor that separates this combo from those with higher rankings. The 7800X3D ensures that the system does not suffer from CPU bottlenecks, but it cannot compensate for the GPU’s limitations at 4K. The result is a system that is outstanding for 1080p and 1440p gaming, with the ability to handle 4K at reduced settings, but it does not reach the heights of combos with more powerful GPUs.
