Doom

The AMD Ryzen 7 5700X paired with the NVIDIA GeForce RTX 4070 delivers a formidable performance profile in Doom, a 2016 FPS title. The measured frame rates across resolutions and settings indicate a system that is heavily optimized for high-refresh-rate gaming, with the data showing a clear interaction between the CPU's Zen 3 architecture and the GPU's Ada Lovelace design. This analysis breaks down the benchmark results to understand where the bottlenecks lie and how this combo stacks against other tested configurations.

Resolution Scaling

The frame rate scaling from 1080p to 4K is a textbook demonstration of GPU-bound behavior emerging as resolution increases. At 1080p with Low settings, the combo achieves 314.3 FPS, but this drops to 205.6 FPS at 1440p and further to 111.6 FPS at 4K. This represents a 64.5% drop in performance from 1080p Low to 4K Low, illustrating that the rendering workload expands significantly with pixel count, placing an increasing strain on the RTX 4070's capabilities.

The scaling pattern shifts depending on the settings preset. With Ultra settings, the frame rate falls from 187.1 FPS at 1080p to 119.7 FPS at 1440p and finally to 69.1 FPS at 4K. The drop from 1440p to 4K at Ultra is 42.3%, which is steeper than the 36.0% drop from 1080p to 1440p. This suggests that at the highest quality settings and 4K resolution, the GPU is being pushed to its limits. Conversely, the scaling at Low settings shows a more linear progression, with a 34.5% drop from 1080p to 1440p and a 45.7% drop from 1440p to 4K. At lower settings, the CPU has more headroom to feed frames, making the GPU's raw output the primary variable. The data indicates that at 1080p and 1440p, the CPU is capable of maintaining very high frame rates, but the GPU becomes the limiting factor as resolution climbs to 4K.

How This Combo Ranks

Within the database of 1681 tested CPU and GPU combinations, this specific pairing holds the 431st position for Doom. This places it in the top 25.6% of all tested combos, indicating a strong overall performance tier. The rank is a composite measure, reflecting the system's ability to sustain high frame rates across the tested resolutions.

The fact that this combo ranks in the 431st spot out of 1681 is notable, especially considering the game's age. It suggests that while the RTX 4070 provides ample graphics horsepower, the Ryzen 7 5700X is not a limiting factor in most scenarios. The high frame rates observed, particularly at 1080p, indicate that this pairing is well-suited for high-refresh-rate monitors. The data shows the system is not just fast, but consistently fast, avoiding the significant frame drops that would push it lower in the rankings. This is a strong result for a mid-range CPU and upper-mid-range GPU combination.

GPU Role

The NVIDIA GeForce RTX 4070 is the primary driver of the visual output, and its specifications directly explain the measured frame rates. The GPU features 12 GB of GDDR6X memory on a 192-bit bus, providing a memory bandwidth of 504.2 GB/s. This bandwidth is sufficient to handle the texture data and geometry at 4K resolution, as evidenced by the playable frame rates at that resolution. The GPU's boost clock of 2475 MHz, running on the Ada Lovelace architecture, allows for the high pixel rates seen in the benchmarks.

The RTX 4070's performance is further contextualized by its benchmark scores. With a Passmark G3D score of 26927 and an average benchmark score of 37283, it sits in the 81st percentile of all GPUs. Its nearest rivals in the database include the AMD Radeon RX Vega 56 and the NVIDIA GeForce RTX 4080 Mobile, with delta percentages of -0.6% and -2.2% respectively. This places the desktop RTX 4070 in a performance class that is slightly above these mobile and older desktop parts. In Doom, the GPU's role is clear: it scales from handling 1080p with ease to providing a solid 4K experience at High settings, with the 4K Ultra preset being the most demanding scenario, yielding an average of 69.1 FPS.

Measured FPS Breakdown

The measured frame rates provide a detailed picture of the system's capabilities across a matrix of resolutions and quality settings. At 1920x1080, the combo is exceptionally fast, with all settings producing over 187 FPS. The Low preset yields an average of 314.3 FPS, which drops to 272.7 FPS on Medium and 231.4 FPS on High. The Ultra preset still manages a very high 187.1 FPS. This indicates that at 1080p, the system is almost certainly CPU-bound in lower settings, as the frame rates are extraordinarily high.

Moving to 2560x1440, the frame rates remain impressive but begin to show the GPU's workload. The Low preset averages 205.6 FPS, while Medium and High deliver 175.2 FPS and 149.4 FPS, respectively. The Ultra preset drops to 119.7 FPS. This resolution is a sweet spot for this combo, offering high refresh rates even on the most demanding preset. At 3840x2160, the GPU becomes the clear bottleneck. The Low preset still achieves 111.6 FPS, which is excellent for 4K. Medium and High settings deliver 97.8 FPS and 80.4 FPS, respectively. The Ultra preset is the most demanding scenario tested, with an average of 69.1 FPS. The data shows a consistent and predictable scaling, with the gap between Low and Ultra settings widening as resolution increases, confirming the GPU's central role in determining final performance.

CPU Role

The AMD Ryzen 7 5700X is the central processing unit, and its architecture is critical to the system's ability to deliver high frame rates. With 8 cores and 16 threads based on the Zen 3 architecture, the CPU has a base clock of 3.40 GHz and a boost clock of 4.60 GHz. The 32 MB of shared L3 cache is a key asset for gaming, as it reduces memory latency and improves data throughput for game logic. The CPU's performance is reflected in its benchmarks, such as a Cinebench R23 multicore score of 22620 and a single-core score of 3193.

The CPU's role in Doom becomes evident when analyzing the frame rates at 1080p. The fact that the system can push 314.3 FPS on Low settings suggests that the CPU is not the bottleneck at this resolution and settings combination. However, the Ryzen 7 5700X's performance percentile of 83 and its average benchmark score of 26214 place it near rivals like the Intel Core i9-11900KF and the AMD Ryzen 5 7600X, with delta percentages of 0.1% and -0.2% respectively. This indicates that the CPU is a solid performer for its class. In this specific game, the CPU's high single-threaded performance is sufficient to feed the RTX 4070 effectively, ensuring that the GPU is the primary determinant of frame rates at higher resolutions. The data shows that this CPU is a strong match for the GPU in this title, providing a balanced platform that excels in producing high frame rates.
