Doom

The AMD Ryzen 7 5700X3D paired with the NVIDIA GeForce GTX 1070 is a classic high-core-count CPU with a mid-range GPU from a previous generation. In Doom, this combination delivers a playable experience across most settings, but the data clearly shows that the GTX 1070 is the primary bottleneck, especially at higher resolutions.

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

The Ryzen 7 5700X3D is an 8-core, 16-thread processor based on the Zen 3 architecture, codenamed Vermeer. It operates with a base clock of 3.00 GHz and a boost clock of 4.10 GHz, and it carries a substantial 96 MB of shared L3 cache. This large cache is particularly beneficial in games that rely on rapid data access, and Doom's fast-paced, level-streaming engine can leverage that. The CPU’s benchmark scores place it in the 82nd percentile among all CPUs, with an average benchmark score of 24673.

Looking at its nearest rivals, the 5700X3D sits extremely close to the Intel Core i7-1360P, which scores 24627 (a delta of 0.2% in favor of the AMD chip). It also edges out the AMD Ryzen 5 7600X3D (24605, +0.3%) and the Intel Core i5-11600 (24559, +0.5%). The only competitor it trails slightly is the AMD Ryzen AI Max 385, which scores 24811, a delta of -0.6% for the 5700X3D. In practical terms, these deltas are negligible, meaning the 5700X3D delivers essentially the same level of CPU performance as its immediate peers.

In Doom, the CPU’s job is to feed the GPU with draw calls and game logic. The measured FPS data shows that even at 1080p with Low settings (157 FPS average), the CPU is not the limiting factor, as the frame rate is still far below the theoretical maximum of this processor. The real constraint emerges from the GPU, which means the 5700X3D has ample headroom to handle Doom’s demands without becoming a bottleneck. This is a scenario where the CPU’s strong multi-threaded performance (evidenced by its 22366 score in Cinebench R23 multicore) is more than sufficient, and the game’s responsiveness is dictated by the graphics card.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce GTX 1070 is built on the Pascal architecture with the GP104 chip, manufactured on a 16 nm process. It has 8 GB of GDDR5 memory on a 256-bit bus, delivering a bandwidth of 256.3 GB/s. Its base clock is 1506 MHz with a boost clock of 1683 MHz, and the memory runs at 2002 MHz (8 Gbps effective). The card features 1920 shading units, 120 TMUs, and 64 ROPs, offering 6.463 TFLOPS of FP32 compute.

The GTX 1070’s average benchmark score is 12331, placing it in the 51st percentile of all GPUs. Its nearest rivals include the NVIDIA Quadro K4200 (12241, +0.7% for the 1070), the NVIDIA GeForce GTX 880M (12490, -1.3%), the NVIDIA GeForce GTX 1650 SUPER (12504, -1.4%), and the NVIDIA Tesla K20Xm (12547, -1.7%). These deltas are small, indicating that the GTX 1070 performs on par with these cards in synthetic tests.

For Doom, the GPU’s 8 GB of VRAM is adequate for the game’s textures at 1080p and 1440p, but the card’s raw compute power is what drives the frame rates. The measured data shows a clear pattern: at 1080p with Low settings, the card averages 157 FPS. However, as settings increase to Ultra, the average drops to 94.9 FPS. This is a 39.5% performance hit from Low to Ultra, which highlights how much the GTX 1070 struggles with higher graphical loads. The GPU’s mid-range standing (51st percentile) confirms that it is not a high-end part, and in Doom, it will require settings adjustments to maintain high refresh rates.

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

The FPS data across resolutions paints a definitive picture of a GPU-bound system. At 1080p with High settings, the system averages 115.7 FPS. Moving to 1440p, the average drops to 76.7 FPS, a 33.7% decrease. At 4K, the average falls to 42.8 FPS, which is a 63% drop from the 1080p result. This scaling is typical for a GPU-limited scenario, where increasing the pixel count directly increases the load on the graphics card.

The story is similar with Low settings. At 1080p, the average is 157 FPS. At 1440p, it drops to 100 FPS (-36.3%), and at 4K, it plummets to 55.7 FPS (-64.5%). The consistent pattern of roughly a 35% drop from 1080p to 1440p and a further 45% drop from 1440p to 4K indicates that the GTX 1070’s fill rate and memory bandwidth are being saturated.

This scaling behavior confirms that the Ryzen 7 5700X3D is not the limiting factor. If the CPU were the bottleneck, we would expect frame rates to remain more constant across resolutions, particularly at lower settings. Instead, the heavy drops at 4K demonstrate that the GPU cannot keep up with the increased pixel workload. For a player targeting 4K, the GTX 1070 will require Low settings to achieve a playable 55.7 FPS average, and even then, it will not be a consistently smooth experience.

FAQ

*Q: Can this system run Doom at 1440p with High settings?*

A: Yes. The measured data shows an average FPS of 76.7 at 2560x1440 with High settings. This is above the 60 FPS threshold, providing a smooth experience for most players.

Q: What is the best resolution for this combo to target 100+ FPS?

A: At 1920x1080 with Low settings, the system achieves an average of 157 FPS. To stay above 100 FPS, you can also use Medium settings at 1080p (135.6 FPS) or High settings at 1080p (115.7 FPS).

Q: How does the GTX 1070 compare to its closest rival, the GTX 1650 SUPER?

A: The GTX 1070 has an average benchmark score of 12331, which is 1.4% higher than the GTX 1650 SUPER's score of 12504. This indicates the 1070 is slightly faster in synthetic tests.

Q: Is the Ryzen 7 5700X3D a strong CPU for gaming?

A: Yes, its average benchmark score of 24673 places it in the 82nd percentile of all CPUs. It is also 0.2% faster than the Intel Core i7-1360P, a popular mobile chip, in average scores.

Q: What is the lowest FPS recorded at 4K?

A: The lowest average FPS at 3840x2160 is 34.6, which occurs with Ultra settings. This is not a playable frame rate for a fast-paced FPS.

Q: Does the CPU hold back the GPU in this game?

A: No. The FPS drops from 1080p to 4K are significant (e.g., from 157 to 55.7 FPS on Low settings), which is a classic sign of a GPU bottleneck. The CPU has enough headroom to handle the game at all tested settings.

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

The following table summarizes the exact measured average FPS values from the data, organized by resolution and settings.

1920x1080 (1080p)

• Low: 157.0 FPS
• Medium: 135.6 FPS
• High: 115.7 FPS
• Ultra: 94.9 FPS

2560x1440 (1440p)

• Low: 100.0 FPS
• Medium: 88.6 FPS
• High: 76.7 FPS
• Ultra: 61.6 FPS

3840x2160 (4K)

• Low: 55.7 FPS
• Medium: 48.5 FPS
• High: 42.8 FPS
• Ultra: 34.6 FPS

The data shows a consistent hierarchy: lowering settings always increases FPS, and lowering resolution has a massive impact. At 1080p, even Ultra settings produce a playable 94.9 FPS average. At 1440p, Ultra dips to 61.6 FPS, which is still playable but close to the edge. At 4K, only Low settings cross the 50 FPS mark, and Ultra is firmly in the 30s.

Settings Recommendations — which preset gives the best experience per the measured rows

For a 60 FPS target, the best experience depends on your display resolution. At 1080p, you can comfortably use Ultra settings, as the 94.9 FPS average provides a high-refresh-rate experience without sacrificing visual quality. If you have a 144 Hz monitor, dropping to High settings (115.7 FPS) is a solid choice, but Medium (135.6 FPS) or Low (157 FPS) will get you closer to that refresh rate ceiling.

At 1440p, the situation is tighter. The Ultra preset averages 61.6 FPS, which is just above 60 FPS, but it may not be consistent. High settings (76.7 FPS) offer a safer margin and are recommended for a smooth, stable experience. Medium settings (88.6 FPS) are even better if you prefer higher frame rates over some visual fidelity.

For 4K gaming, this combination is not well-suited for high settings. The data shows that only Low settings (55.7 FPS) achieve a playable average. Medium (48.5 FPS) and High (42.8 FPS) are below the 60 FPS line and will feel less fluid. Therefore, if 4K is your target, you must accept Low settings for a near-60 FPS experience, or consider reducing the resolution to 1440p for a much better balance. In summary, the GTX 1070 is the limiting factor, and the Ryzen 7 5700X3D ensures that the CPU will never be the reason for a frame rate drop.
