Doom

# How This Combo Ranks

The AMD Ryzen 9 9900X3D paired with the NVIDIA GeForce RTX 3080 Ti lands at rank 716 out of 2930 tested combos in Doom. That places it in the top quarter of all combinations in the database, which is a strong result for a 2016 FPS title that is now well understood by drivers and game engines alike. The combo’s position reflects a balanced pairing: the CPU sits at the 91st percentile among all processors, while the GPU holds the 83rd percentile among all graphics cards. Neither component is holding the other back to a dramatic degree, though the data suggests the GPU is the more likely bottleneck at higher resolutions.

Looking at the rivals in the database, the Ryzen 9 9900X3D’s average benchmark score of 54762 is within 0.6% of the Intel Core Ultra 5 245KF’s 55093, and it leads the Intel Core Ultra 5 245K by 1.3% (54053). The gap widens slightly against the Intel Xeon 6505P at 2% (53701) and the Intel Core i7-14700F at 2.1% (53620). These are tight margins, meaning the CPU choice here is not dramatically better or worse than its nearest competitors in synthetic workloads. For Doom specifically, the measured FPS data shows the combo delivering playable frame rates across all tested settings and resolutions, with the notable exception of 4K Ultra where it dips to an average of 66 FPS.

The GPU’s nearest rivals paint a different picture. The RTX 3080 Ti’s average benchmark score of 41187 is 0.8% ahead of the AMD Radeon Pro 5300 (40870), 1.2% behind the NVIDIA Tesla M40 24 GB (41707), and 1.7% behind the standard Tesla M40 (41897). Interestingly, the RTX 3080 Ti is 2% ahead of the much newer NVIDIA GeForce RTX 5070 (40377). This suggests that in raw benchmark terms, the 3080 Ti remains competitive with modern mid-range offerings, though the measured FPS in Doom will tell the real story for gaming.

Settings Recommendations

For 1920x1080, the data shows that Low settings deliver an average of 312 FPS, Medium hits 272 FPS, High achieves 230 FPS, and Ultra drops to 188 FPS. All four presets are far beyond the refresh rate of most monitors, so the choice here depends on whether you prioritize maximum frame rates or visual fidelity. Given that the difference between Low and Ultra is 124 FPS, but even Ultra stays above 180 FPS, the practical recommendation is to use High or Ultra at 1080p unless you are chasing esports-level refresh rates. High offers a 42 FPS advantage over Ultra while retaining most visual quality, making it the sweet spot for competitive play.

At 2560x1440, the measured results show Low averaging 202 FPS, Medium at 176 FPS, High at 149 FPS, and Ultra at 122 FPS. The Medium preset records a minimum of 150 FPS and a maximum of 202 FPS, which indicates consistency. For 1440p, High is the recommended starting point because it stays above 144 FPS on average, which matches most high-refresh monitors. If you have a 165Hz or 240Hz display, dropping to Medium gains you 27 FPS on average while still looking good. Ultra at 122 FPS is still playable but does not fully utilize a 144Hz panel, so it is only worth it if you prioritize image quality over smoothness.

For 3840x2160, the numbers tighten considerably. Low averages 109 FPS, Medium averages 95 FPS with a minimum of 81 FPS, High averages 81 FPS, and Ultra falls to 66 FPS. At 4K, the recommendation shifts to Medium as the best balance, because it maintains an average above 90 FPS while the minimum of 81 FPS stays within VRR range on most G-Sync or FreeSync displays. High is borderline at 81 FPS average, and Ultra at 66 FPS is only suitable for slower-paced play or if you have a 60Hz monitor and do not mind occasional dips. The data clearly shows diminishing returns beyond Medium at 4K for this combo.

FAQ

Q: Is this combo capable of running Doom at 4K with high refresh rates?

A: At 3840x2160, the measured average FPS is 81 on High and 66 on Ultra. Medium achieves 95 FPS average with a minimum of 81 FPS. For 120Hz or higher displays, you would need to use Medium or lower settings, as High and Ultra do not consistently reach 120 FPS.

Q: How does the Ryzen 9 9900X3D compare to its closest CPU rivals in synthetic benchmarks?

A: The Ryzen 9 9900X3D scores 54762 on average, which is 0.6% below the Intel Core Ultra 5 245KF (55093), 1.3% above the Intel Core Ultra 5 245K (54053), 2% above the Intel Xeon 6505P (53701), and 2.1% above the Intel Core i7-14700F (53620). These differences are minor in real-world gaming.

Q: What is the best settings preset for a 1440p 144Hz monitor?

A: The measured data shows High at 2560x1440 averaging 149 FPS, which is above the 144Hz threshold. Medium averages 176 FPS for additional headroom. Ultra drops to 122 FPS, which would not fully saturate a 144Hz panel.

Q: Does the RTX 3080 Ti outperform the newer RTX 5070 in this database?

A: Based on average benchmark scores, the RTX 3080 Ti scores 41187, which is 2% higher than the RTX 5070’s 40377. This is a synthetic comparison, and actual game performance may vary, but the data shows the older card holding its own.

Q: How much FPS difference is there between Low and Ultra settings at 1080p?

A: At 1920x1080, Low averages 312 FPS while Ultra averages 188 FPS. That is a 124 FPS difference, or roughly 66% more performance on Low. Medium sits at 272 FPS and High at 230 FPS, so the scaling is not linear across presets.

Q: Is the CPU or GPU more likely to limit performance in Doom?

A: Given that the CPU is at the 91st percentile and the GPU at the 83rd percentile, and that frame rates drop significantly at higher resolutions, the GPU appears to be the limiting factor at 4K. At 1080p, both components are likely sufficient, as even Ultra stays above 188 FPS.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. Low settings produce an average of 312 FPS, with Medium at 272 FPS and a recorded minimum of 231 FPS and maximum of 313 FPS. High settings average 230 FPS, while Ultra drops to 188 FPS. The gap between Low and Ultra is 124 FPS, which is substantial but expected for a game like Doom that scales well with GPU load. The Medium preset’s minimum of 231 FPS indicates that even in heavy scenes, the combo stays well above 200 FPS, making it ideal for 240Hz monitors.

Moving to 2560x1440, the performance remains strong but shows the expected decline. Low averages 202 FPS, Medium averages 176 FPS with a minimum of 150 FPS and maximum of 202 FPS, High averages 149 FPS, and Ultra averages 122 FPS. The Medium preset at 1440p has a minimum that matches the average of High, which means you get consistent performance without major dips. High at 149 FPS is just above the 144Hz mark, while Ultra falls below it, so the recommendation for high-refresh 1440p gaming is clearly Medium or High.

At 3840x2160, the frame rates drop more noticeably. Low averages 109 FPS, Medium averages 95 FPS with a minimum of 81 FPS and maximum of 110 FPS, High averages 81 FPS, and Ultra averages 66 FPS. The Medium preset’s minimum of 81 FPS is identical to the average of High, showing that the GPU is struggling to maintain high frame rates at 4K. Even Low at 109 FPS is below 120 FPS, so this combo is not ideal for 4K 120Hz gaming unless you are willing to accept settings below Medium. The data shows a clear pattern: each resolution step down from 4K to 1440p roughly doubles the headroom, and dropping from 1440p to 1080p adds another significant boost.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is built on the Ampere architecture with a GA102 chip manufactured on Samsung’s 8 nm process. It packs 28,300 million transistors on a 628 mm² die, with a transistor density of 45.1M per mm². The GPU has 10,240 shading units, 320 texture mapping units, and 112 raster output pipelines. It also includes 80 RT cores and 320 tensor cores, which are relevant if you enable ray tracing or DLSS in other titles, though Doom’s measured data does not specify these features.

Memory configuration is substantial: 12 GB of GDDR6X on a 384-bit bus, delivering a bandwidth of 912.4 GB/s. The memory clock runs at 1188 MHz, which translates to 19 Gbps effective. This bandwidth is crucial for 4K gaming, where large textures and high resolutions demand rapid data transfer. The GPU’s base clock is 1365 MHz with a boost clock of 1665 MHz. The pixel rate is 186.5 GPixel/s, and the texture rate is 532.8 GTexel/s. FP32 performance is rated at 34.10 TFLOPS, with FP16 at the same 34.10 TFLOPS (1:1 ratio).

In terms of measured FPS, the GPU’s role becomes clear when comparing resolutions. At 1080p Low, the GPU is not the bottleneck, as the CPU can feed it enough frames to reach 312 FPS. At 4K Ultra, the GPU is clearly the limiting factor, as the average drops to 66 FPS. The RTX 3080 Ti’s percentile rank of 83 among all GPUs indicates it is a high-end card, but not top-tier in the current database. Its average benchmark score of 41187 places it close to the Radeon Pro 5300 (40870) and slightly behind the Tesla M40 variants (41707 and 41897), while being 2% ahead of the RTX 5070 (40377).

The GPU’s power requirements are notable: a TDP of 350 W, a suggested PSU of 750 W, and a single 12-pin power connector. The card is dual-slot, measures 285 mm in length, 112 mm in height, and 40 mm in width. It supports PCIe 4.0 x16 and has display outputs of 1x HDMI 2.1 and 3x DisplayPort 1.4a. For Doom, the GPU’s 12 GB of VRAM is more than sufficient, as the game does not typically exceed 6 GB even at 4K Ultra in most scenarios. The high bandwidth of 912.4 GB/s helps maintain consistent frame times, as seen in the Medium preset’s minimum FPS values across all resolutions.

CPU Role

The AMD Ryzen 9 9900X3D is a 12-core, 24-thread processor based on the Zen 5 architecture, codenamed Granite Ridge. It is manufactured on TSMC’s 4 nm process with 16,630 million transistors across a 2x 70.6 mm² die configuration. The base clock is 4.40 GHz with a boost clock of 5.50 GHz, and it has a TDP of 120 W. The CPU supports DDR5 memory in dual-channel mode with a bandwidth of 89.6 GB/s, and it includes ECC memory support. It uses the AMD Socket AM5 and has PCIe Gen 5 with 24 lanes from the CPU.

Cache configuration is substantial: 80 KB of L1 per core, 1 MB of L2 per core, and a large 128 MB of L3 cache. This large L3 cache is a hallmark of the X3D series and can benefit games that are sensitive to cache latency. The CPU’s benchmark results show strong multi-threaded performance: Cinebench R23 multi-core scores 47737, while single-core scores 6739. Geekbench multi-core is 22884, and single-core is 3041. Passmark multi-thread scores 56154, with single-thread at 4646. The 3DMark results range from 1269 for single-thread to 13795 for max threads.

In the context of Doom, the CPU’s role is less critical than the GPU, given that the game is well-optimized and can run on older hardware. The measured FPS data shows that even at 1080p Low, the combo reaches 312 FPS, which suggests the CPU is not a bottleneck at lower resolutions. The Ryzen 9 9900X3D’s percentile rank of 91 among all CPUs indicates it is a top-tier processor, and its nearest rivals are all within 2.1% of its average score. The Intel Core Ultra 5 245KF is 0.6% ahead, while the Core i7-14700F is 2.1% behind.

The CPU’s high boost clock of 5.50 GHz and 128 MB of L3 cache likely contribute to consistent frame pacing in Doom, which is a fast-paced FPS that can be sensitive to frame time spikes. The 12 cores and 24 threads are more than sufficient for this game, as Doom typically uses fewer than 8 threads. The CPU’s single-thread performance, as shown by Cinebench R23 single-core of 6739, is strong and helps ensure that the game’s main thread does not become a limiting factor. The 3DMark 2-thread score of 2512 and 4-thread score of 4885 indicate that even lightly threaded workloads are handled well.

The CPU’s memory bandwidth of 89.6 GB/s is adequate for Doom, though the game does not stress memory as much as newer titles. The 4 nm process and 120 W TDP mean the CPU runs efficiently, which is beneficial for sustained gaming sessions where thermal throttling could otherwise affect performance. The launch MSRP of $599 reflects its high-end positioning, though it is not directly comparable to the GPU’s price point. Ultimately, the data shows that the Ryzen 9 9900X3D provides more CPU headroom than Doom requires, meaning the RTX 3080 Ti is the primary determinant of frame rates at higher resolutions.
