Doom

The AMD Ryzen 9 9900X paired with the NVIDIA GeForce RTX 5070 Ti delivers exceptional performance in Doom, a game from 2016 that scales impressively across modern hardware. The measured data shows this combination is capable of high refresh rate gaming at every resolution, with the GPU becoming the primary limiting factor as resolution increases. This analysis breaks down the benchmark results, focusing on resolution scaling, component roles, and how this specific combo compares to 1680 other tested configurations.

Resolution Scaling

The FPS drop from 1080p to 4K reveals a classic GPU-bound scenario. At 1080p with Low settings, the combo achieves 386.2 FPS, but this falls to 136.5 FPS at 4K Low—a 64.6% reduction in frame rate. The pattern is consistent across all settings. Moving from 1440p to 4K at High settings, the average FPS drops from 185.5 to 101.8, a 45.1% decrease. This steep decline indicates that the RTX 5070 Ti is the dominant factor at higher resolutions, while the CPU has ample headroom at lower resolutions.

The scaling between 1080p and 1440p is less severe. At Ultra settings, the game runs at 233.4 FPS in 1080p and 146.9 FPS in 1440p, a 37.1% drop. This suggests that even at 1440p, the system is still partially CPU-limited in less demanding scenes. However, the transition from 1440p to 4K at Ultra shows a 42.9% reduction (146.9 to 83.8 FPS), which is a strong indicator that the GPU is now fully saturated. The data clearly shows that for 4K gaming, the RTX 5070 Ti is the bottleneck, while at 1080p, the Ryzen 9 9900X's 12 cores and 24 threads are more than sufficient to feed the GPU.

GPU Role

The NVIDIA GeForce RTX 5070 Ti is built on the Blackwell 2.0 architecture with a GB203 chip on a 5 nm process. It features 16 GB of GDDR7 memory on a 256-bit bus, delivering 896.0 GB/s of bandwidth. The GPU operates at a base clock of 2295 MHz and boosts to 2452 MHz. This memory configuration is crucial for Doom, as the game's texture-heavy environments benefit from high bandwidth, especially at 4K resolution.

The GPU's 8960 shading units and 280 texture mapping units handle Doom's Vulkan-based rendering efficiently. The measured FPS at 4K Ultra (83.8 FPS) shows that the card is working hard, but the 16 GB VRAM buffer prevents any memory-related stutters. At 1080p Low, the 386.2 FPS result demonstrates the card's raw compute capability, with FP32 performance rated at 43.94 TFLOPS. The RTX 5070 Ti sits in the 87th percentile of all GPUs, and its average benchmark score of 52086 is nearly identical to the NVIDIA GeForce RTX 4080, which scores 52085 (0% delta). This indicates that in synthetic benchmarks, the 5070 Ti matches the previous generation's flagship.

How This Combo Ranks

In Doom specifically, this CPU-GPU combination ranks 127th out of 1681 tested combos, placing it in the top 7.6% of all configurations. This is a strong result, but it's not at the absolute top, suggesting that other combos with higher-end GPUs or CPUs achieve higher frame rates. The CPU alone sits in the 94th percentile of all processors, with an average benchmark score of 54450. Its nearest rival, the AMD Ryzen 9 9900X3D, scores 54681, a mere 0.4% difference. The Intel Core i7-14700F scores 54097, which is 0.7% lower, while the Intel Core Ultra 5 245K and 245KF score 55304 and 55421 respectively, placing them 1.5% and 1.8% higher.

The GPU's percentile ranking of 87th is slightly lower than the CPU's 94th, which explains why the combo rank (127th) is not higher. The data suggests that while the Ryzen 9 9900X is a top-tier CPU, the RTX 5070 Ti, while excellent, is not the absolute fastest GPU available. This combo is well-balanced, but for those seeking the very top of the leaderboard in Doom, a more powerful GPU would yield higher rankings.

Measured FPS Breakdown

At 1920x1080, the combo delivers outstanding results across all settings. Low settings produce 386.2 FPS, Medium 335.3 FPS, High 286 FPS, and Ultra 233.4 FPS. These numbers indicate that at 1080p, the system is never the limiting factor, and even at Ultra, the frame rate is high enough for 240 Hz monitors.

Moving to 2560x1440, the performance remains very strong. Low settings hit 247.4 FPS, Medium 216.7 FPS, High 185.5 FPS, and Ultra 146.9 FPS. The drop from Low to Ultra at 1440p is 40.6%, showing that settings have a significant impact at this resolution, but even the lowest result is well above 144 Hz.

At 3840x2160, the GPU begins to show its limits. Low settings average 136.5 FPS, Medium 118.9 FPS, High 101.8 FPS, and Ultra 83.8 FPS. The difference between Low and Ultra at 4K is 38.6%, which is less pronounced than at lower resolutions, confirming that the GPU is becoming the bottleneck. All 4K results are playable, but only Low and Medium settings exceed 120 FPS, making them the sweet spot for high refresh rate 4K displays.

FAQ

Q: Is this combo better suited for 1080p or 4K gaming in Doom?

A: The data shows the combo excels at 1080p, achieving 386.2 FPS on Low settings and 233.4 FPS on Ultra. At 4K, it still performs well with 136.5 FPS on Low and 83.8 FPS on Ultra, but the GPU becomes the limiting factor, making 1080p the resolution where the CPU's power is fully utilized.

Q: How does the RTX 5070 Ti compare to the RTX 4080 in raw performance?

A: The average benchmark scores are nearly identical: the RTX 5070 Ti scores 52086, while the RTX 4080 scores 52085, a 0% delta. This indicates that in synthetic tests, the two GPUs perform at the same level, despite being from different generations.

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

A: At 2560x1440, Low settings produce 247.4 FPS, while Ultra settings produce 146.9 FPS. This is a 40.6% reduction in frame rate, showing that settings have a substantial impact on performance at this resolution.

Q: Does the Ryzen 9 9900X bottleneck the RTX 5070 Ti at any resolution?

A: At 1080p, the CPU is not a bottleneck, as evidenced by the 386.2 FPS result on Low settings. At 4K, the GPU is clearly the limiting component, with frame rates dropping significantly. The CPU only becomes less relevant as resolution increases.

Q: What is the combo's overall ranking among all tested systems in Doom?

A: The combo ranks 127th out of 1681 tested combinations, placing it in the top 7.6% of all configurations. This is a strong result, but not the absolute top, indicating that some other systems achieve higher frame rates.

Q: How much faster is the 9900X compared to the i7-14700F?

A: The Ryzen 9 9900X has an average benchmark score of 54450, while the Intel Core i7-14700F scores 54097. This gives the AMD chip a 0.7% advantage in synthetic benchmarks, a small but measurable lead.

CPU Role

The AMD Ryzen 9 9900X is a 12-core, 24-thread processor based on the Zen 5 architecture (Granite Ridge) on a 4 nm process. It has a base clock of 4.40 GHz and a boost clock of 5.60 GHz, with a 120 W TDP. The CPU features 64 MB of shared L3 cache and 1 MB of L2 cache per core, which helps with game loading and asset streaming. Its memory bandwidth is rated at 89.6 GB/s using dual-channel DDR5, and it supports PCIe Gen 5 with 24 lanes.

In Doom, this CPU's high single-thread performance is crucial. Its 3dmark single-thread score of 1286 and passmark single-thread score of 4672 indicate strong per-core performance, which allows the GPU to be fully utilized at 1080p. The multi-core performance is equally impressive, with a cinebench R23 multi-core score of 46438. However, Doom is not heavily multi-threaded, so the 12 cores provide diminishing returns beyond what is needed to maintain high frame rates.

The CPU's 94th percentile ranking among all processors confirms its top-tier status. Its nearest rival, the 9900X3D, is only 0.4% faster on average, while the Intel Core Ultra 5 245K is 1.5% faster. This places the 9900X in a competitive position, though not the absolute fastest. For Doom, the CPU's role is to feed the GPU efficiently, and the measured FPS at 1080p (386.2 FPS on Low) shows it does so without issue. The 12-core, 24-thread configuration also ensures that any background tasks or streaming software will not impact gaming performance, making this a solid choice for a high-refresh-rate gaming rig.
