Doom

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 5070 Ti delivers a performance profile in Doom that is heavily dictated by resolution and graphics settings. The measured data reveals a system capable of extreme frame rates at lower resolutions, while 4K Ultra presents a more demanding scenario. This analysis breaks down the combination's behavior, ranking, and the specific roles of its core components.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial and clearly indicates a shift in the bottleneck. At 1920x1080 with Low settings, the combo produces an average of 382.7 FPS. Moving to 2560x1440 at Low settings reduces that to 248.6 FPS, a significant 134.1 FPS decline. At 3840x2160 with Low settings, the average further drops to 132.3 FPS. This steep scaling curve demonstrates that the GPU is the primary limiting factor at higher resolutions, while the CPU has ample headroom to push frames at 1080p.

The scaling pattern holds across all settings presets. At High settings, the average FPS drops from 281 at 1080p to 186.1 at 1440p, and finally to 102.2 at 4K. Similarly, at Ultra settings, the frame rate falls from 230.2 at 1080p to 146.9 at 1440p and then to 78.9 at 4K. The consistent pattern of performance halving or nearly halving with each step up in resolution points to the RTX 5070 Ti's rendering workload being the dominant constraint. The 1080p results, particularly the 382.7 FPS at Low, suggest that the Ryzen 9 7900X’s processing power is more than sufficient for this game’s engine at lower resolutions.

The data indicates that for competitive play at 1080p, this combination is overkill, as even the Ultra preset achieves 230.2 FPS. The transition to 1440p is the sweet spot for high-refresh-rate monitors, with all settings except Ultra exceeding 186 FPS. At 4K, the GPU workload becomes severe, and the 78.9 FPS at Ultra shows that maximizing visual fidelity will come at the cost of high refresh rates.

How This Combo Ranks

In the database of tested hardware combinations for Doom, this specific pairing of the Ryzen 9 7900X and RTX 5070 Ti holds a rank of 146 out of 1681 combos. This places it in the top percentile of all tested systems, indicating a very high-performing configuration for this title. The rank of 146 puts it in the top 8.7% of all tested combos, which is a strong showing for a modern mid-to-high-end setup.

This performance level is largely a result of the GPU's capability. The RTX 5070 Ti sits at the 87th percentile among all GPUs in the database, with an average benchmark score of 52086. Its nearest rival, the NVIDIA GeForce RTX 4080, has a nearly identical average score of 52085, a delta of 0%. This suggests the 5070 Ti's raw compute power is on par with the previous generation's flagship. The CPU, the Ryzen 9 7900X, is also a high performer, sitting at the 93rd percentile among all CPUs with an average benchmark score of 50556. Its nearest rival, the Intel Core Ultra 5 235, has a delta of -0.1% with an average score of 50598, indicating the 7900X is essentially tied with that chip in overall synthetic benchmarks.

The combination of a top-tier CPU and a high-end GPU results in a system that is ranked very highly in Doom. The data confirms that the 7900X does not bottleneck the 5070 Ti, allowing the GPU to perform to its full potential. The ranking reflects a balanced and powerful system for this specific game.

Measured FPS Breakdown

The measured performance data provides a clear picture of how the system scales with resolution and graphical fidelity.

At 1920x1080, the system is clearly CPU-bound or engine-limited, as even the most demanding preset produces a high frame rate. The Low preset averages 382.7 FPS, Medium averages 336 FPS, and High averages 281 FPS. The Ultra preset still manages a robust 230.2 FPS, showing that the Ryzen 9 7900X provides enough processing power to maintain high frame rates even when the GPU is tasked with more work.

Moving to 2560x1440, the GPU begins to show its limitations. The Low preset averages 248.6 FPS, which is still excellent for high-refresh-rate gaming. Medium averages 217.5 FPS, and High averages 186.1 FPS. The Ultra preset drops to 146.9 FPS, which is playable but indicates that the GPU is now the primary bottleneck. The scaling from Low to Ultra at this resolution shows a 101.7 FPS swing, highlighting the impact of settings on the GPU's workload.

At 3840x2160, the GPU is definitively the limiting factor. The Low preset averages 132.3 FPS, which is a massive drop from 1080p. Medium averages 115.5 FPS, and High averages 102.2 FPS. The Ultra preset brings the average down to 78.9 FPS. This data shows that while the game is playable at 4K, achieving high refresh rates requires lowering the settings from Ultra. The difference between Low and Ultra at 4K is 53.4 FPS, demonstrating the extreme sensitivity of the GPU to settings at this resolution.

GPU Role

The NVIDIA GeForce RTX 5070 Ti is the primary driver of performance in this configuration, particularly at higher resolutions. The GPU's benchmark data shows it performs at the 87th percentile, with an average score of 52086. It is built on the Blackwell 2.0 architecture and utilizes 8960 shading units. The GPU has a base clock of 2295 MHz and a boost clock of 2452 MHz. It also features 70 RT cores and 280 tensor cores, which are relevant for games that support ray tracing and DLSS, though the measured Doom data does not specify whether these features were enabled.

The GPU is equipped with 16 GB of GDDR7 memory on a 256-bit bus. This provides a memory bandwidth of 896.0 GB/s. This high bandwidth is crucial for 4K gaming, where large textures and high resolutions demand rapid data transfer. The 16 GB capacity is more than sufficient for Doom's requirements and provides headroom for future titles. The GPU's memory clock is listed as 1750 MHz with 28 Gbps effective speed.

The performance deltas to its nearest rivals are telling. It is exactly matched with the RTX 4080, showing it offers comparable raw performance. It is 2.5% faster than the NVIDIA RTX A1000 and 0.8% slower than the AMD Radeon RX 7700S. The measured FPS data aligns with this, showing the GPU's capability to handle 4K at high settings but struggling to maintain very high frame rates at 4K Ultra, where the average drops to 78.9 FPS. The GPU's role is the main bottleneck at 4K, where its processing power determines the final frame rate.

CPU Role

The AMD Ryzen 9 7900X provides the processing foundation for this pairing. With 12 cores and 24 threads, it offers substantial multi-threading capability. Its base clock is 4.70 GHz, and it can boost up to 5.60 GHz. This high boost clock is particularly beneficial for games like Doom, which rely on high single-core performance for game logic and physics. The CPU's 64 MB of shared L3 cache helps keep frequently accessed data close to the cores, reducing latency.

In benchmark tests, the 7900X scores at the 93rd percentile among all CPUs, with an average score of 50556. Its performance in multi-threaded tests is strong; for example, it scores 43695 in Cinebench R23 multicore and 12536 in 3dmark_max_threads. Single-thread performance is also high, with a Cinebench R23 single-core score of 6168 and a 3dmark_single_thread score of 1093.

The CPU's role in Doom is evident from the resolution scaling analysis. At 1080p, where the GPU has less work, the CPU is able to push frame rates to 382.7 FPS on Low settings. This indicates that the CPU is not a bottleneck at this resolution. As the resolution increases, the frame rate drops, showing the GPU becomes the limiting factor. The data suggests the 7900X has enough headroom to fully feed the RTX 5070 Ti in this game, as frame rates scale down with resolution rather than being capped by CPU performance. The CPU's performance is essentially tied with its nearest rivals, showing a delta of -0.1% against the Intel Core Ultra 5 235 and -0.4% against the AMD Ryzen 9 5900XT, confirming it is a top-tier processor that will not hold back a high-end GPU in this title.
