Doom

The AMD Ryzen 9 9900X3D paired with the NVIDIA GeForce RTX 3080 delivers a dominant performance profile in Doom, securing the 787th position out of 2930 tested combinations. This placement in the 73rd percentile of all combos indicates a system that is significantly above average for this title, though it stops short of the top tier reserved for the most extreme hardware. The data shows a pairing where the GPU is the primary driver of frame rates, with the CPU providing ample headroom to prevent bottlenecks even at lower resolutions.

How This Combo Ranks

The combo's rank of 787 out of 2930 tested configurations places it squarely in the upper quartile of all systems benchmarked for Doom. This is a strong showing, suggesting that the vast majority of the 2,930 possible combinations tested will deliver lower average frame rates. The data positions this pairing as a high-performance option, but the ranking also reveals that a significant number of other setups—likely featuring newer or higher-end GPUs—manage to outperform it. The 787th rank indicates that while this system will obliterate most titles at high settings, it is not the absolute pinnacle of performance for this specific game. The position confirms the RTX 3080's enduring capability, but it also reflects the relentless pace of hardware advancement, as nearly 800 other combos, likely with more recent graphics cards, are able to achieve higher frame rates.

In the context of the entire benchmark database, this result is a clear indicator of a high-refresh-rate gaming machine for 1080p and 1440p, with the capability to handle 4K at playable speeds. The rank shows that the combination is well-balanced for the game's demands, avoiding the pitfall of a massive CPU bottleneck that would drag the score down. The fact that it is in the 787th spot rather than the top 100 suggests that the RTX 3080, while powerful, is the limiting factor when compared to combinations with newer, more powerful GPUs. This is a classic case of a very capable last-generation flagship GPU still holding its own, but being outpaced by the current generation's top-end silicon.

GPU Role

The NVIDIA GeForce RTX 3080 is the workhorse of this combination, and its specifications directly explain the measured frame rates. The GPU features 10 GB of GDDR6X memory on a 320-bit bus, providing a substantial 760.3 GB/s of memory bandwidth. This high bandwidth is critical for a fast-paced FPS like Doom, as it allows the GPU to quickly stream texture and geometry data, preventing stutters and ensuring smooth performance. The 10 GB capacity is also sufficient for the game's requirements at the tested resolutions, as none of the measured results indicate a memory capacity bottleneck.

At the heart of the RTX 3080 is the GA102 chip, built on Samsung's 8 nm process. It contains 8,704 shading units, 272 texture mapping units, and 96 ROPs, which are the fundamental building blocks for rendering the game's graphics. These are supported by 68 RT cores and 272 Tensor cores, which, while not directly used for traditional rasterization in Doom, are part of the GPU's feature set for ray tracing and DLSS. The GPU's clocks are set at a base of 1440 MHz and a boost of 1710 MHz, which allows it to reach a peak FP32 performance of 29.77 TFLOPS. This raw compute power is what enables the high frame rates observed, especially at lower resolutions where the CPU is not the limiting factor.

The performance data supports the conclusion that the GPU is the primary performance driver. For instance, in the transition from 1920x1080 to 2560x1440 at Ultra settings, the average FPS drops from 181 to 117, a significant decline that indicates the GPU is working harder to render more pixels. This trend continues to 3840x2160, where the average FPS at Ultra falls to 63. This scaling is typical for a GPU-bound scenario, where the CPU has enough horsepower to feed the GPU with data, but the GPU's rendering capability becomes the constraint as resolution increases. The RTX 3080's role is to deliver the high polygon counts and complex shaders of Doom, and the data shows it does so effectively across all tested settings.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target resolution and refresh rate. The data shows a clear hierarchy of performance across the four settings presets: Low, Medium, High, and Ultra. For users with high-refresh-rate 1080p monitors (144Hz or higher), the High preset is the clear recommendation. At 1920x1080, the High preset delivers an average of 221 FPS, which is well above the refresh rate of most monitors. The Ultra preset at 1080p, while offering higher visual fidelity, still achieves a very respectable 181 FPS average, making it a viable choice for those who prioritize image quality but it comes with a significant 40 FPS penalty compared to High.

At 2560x1440, the High preset again offers the best balance. The average of 143 FPS is perfectly suited for a 144Hz monitor, providing a smooth and responsive experience. The Medium preset at 1440p also delivers a high 170 FPS average, which could be preferred if the user wants a higher frame rate buffer or has a 165Hz+ monitor, but High offers a better visual experience with a smaller performance hit than Ultra. The Ultra preset at 1440p, with an average of 117 FPS, is still playable, but it dips below the 144 FPS threshold that many competitive players consider the target.

For 4K gaming at 3840x2160, the landscape changes. The Medium preset is the best choice for a playable experience, yielding an average of 92 FPS. The High preset at 4K drops to 78 FPS average, which is still smooth, but the Medium preset's higher frame rate provides a more consistent feel. The Ultra preset at 4K is the only one that dips below 60 FPS, averaging 63 FPS, which is on the edge of what is considered a smooth experience for a fast-paced shooter. The Low preset, while achieving 105 FPS at 4K, would significantly degrade visual quality. Therefore, for the best experience at 4K, Medium is the recommended starting point, with High as an option for those who prefer higher fidelity over a few extra frames per second.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the combo's performance across nine different resolution and settings combinations. At 1920x1080, the performance is exceptionally high, with the Low preset hitting an average of 301 FPS. The Medium preset averages 262 FPS, with a minimum of 223 and a maximum of 301. High settings average 221 FPS, while the Ultra preset still manages a very high 181 FPS. This resolution is clearly where the combo shines, providing frame rates that are more than sufficient for even the most demanding esports monitors.

Moving to 2560x1440, the frame rates remain impressive but show the expected decline as pixel count increases. The Low preset averages 195 FPS, and the Medium preset averages 170 FPS, with a measured minimum of 144 and maximum of 195. The High preset averages 143 FPS, which is the sweet spot for 144Hz displays, and the Ultra preset averages 117 FPS. The data shows that even at this higher resolution, the RTX 3080 is still capable of delivering high refresh rate performance, especially on the Medium and High presets.

At 3840x2160, the performance becomes more demanding. The Low preset averages 105 FPS, while the Medium preset averages 92 FPS, with a minimum of 78 and a maximum of 106. The High preset averages 78 FPS, and the Ultra preset is the most demanding, averaging 63 FPS. This indicates that while 4K is playable, it requires a compromise on settings to maintain a high frame rate. The Medium preset provides the best balance of visual fidelity and performance at this resolution, offering a 92 FPS average that keeps the game feeling fluid. The Ultra preset, while playable, is likely to feel less responsive in intense combat scenarios due to its lower frame rate.

CPU Role

The AMD Ryzen 9 9900X3D serves as the central processor in this combo, and its specifications are more than adequate to support the RTX 3080. With 12 cores and 24 threads based on the Zen 5 architecture, this CPU provides a massive amount of parallel processing power. The high core count is not strictly necessary for a game like Doom, which is often more dependent on single-thread performance, but it ensures that any background tasks or game logic threads are handled without impacting frame times. The CPU's base clock is 4.40 GHz, and it can boost up to 5.50 GHz, which is a very high frequency for a 12-core processor and is critical for maintaining high minimum frame rates.

The CPU's cache hierarchy is also a key feature. It includes a large 128 MB L3 cache, which is a hallmark of the X3D series. This large cache helps to reduce memory latency and improve performance in games that are sensitive to it. While Doom may not be as cache-dependent as some other titles, the large L3 cache still contributes to the CPU's strong overall performance. The benchmark results for the CPU are impressive, with a Cinebench R23 multi-core score of 47,737 and a single-core score of 6,739. These scores indicate a level of performance that is far beyond what is needed to drive the RTX 3080 in this game.

The CPU's performance is so high that it is unlikely to be the bottleneck in this system, even at 1080p where frame rates are extremely high. The measured FPS data supports this, as the frame rates scale consistently with resolution, which is a clear sign of a GPU-bound scenario. The 3DMark 16-thread score of 12,490 and the Passmark multi-thread score of 56,154 further reinforce that the CPU is a top-tier performer. The Ryzen 9 9900X3D provides a rock-solid foundation, ensuring that the RTX 3080 can operate at its full potential without being held back by the processor. This makes the combo a very well-matched pairing, where the CPU's role is to provide a vast performance buffer, guaranteeing that the GPU is always the limiting factor.
