Doom

The pairing of AMD’s Ryzen 5 5600G with NVIDIA’s GeForce RTX 4090 presents a striking contrast in hardware generations and performance tiers. The data for Doom reveals a system capable of extreme frame rates, yet the distribution of scores across resolutions and settings tells a nuanced story about which component is truly steering the ship. This analysis breaks down the measured results to understand the dynamics of this specific combination.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 5600G is a 6-core, 12-thread processor based on the Zen 3 architecture, with a base clock of 3.90 GHz and a boost clock of 4.40 GHz. It features a 16 MB L3 cache and operates on a dual-channel DDR4 memory bus with a bandwidth of 51.2 GB/s. This CPU sits in the 78th percentile of all processors, with an average benchmark score of 19,983.

Its nearest rivals in synthetic testing include the Intel Core i7-11600H (avg score 19,949, deltaPct 0.2), the Intel Core i7-11800H (avg score 20,024, deltaPct -0.2), and the AMD EPYC 7713P (avg score 20,024, deltaPct -0.2). The data shows the 5600G is essentially neck-and-neck with these parts, with a performance delta of less than one percent in either direction. This indicates that while the CPU is not a top-tier part, its single-thread and multi-thread capabilities are balanced enough to avoid being a catastrophic bottleneck in most scenarios.

In the context of Doom, a game known for its id Tech engine efficiency, the CPU’s role is primarily to feed the GPU with draw calls and game logic. The measured frame rates at 1080p, which often expose CPU limitations, reach as high as 330.7 fps on Low settings. This suggests the 5600G’s six cores are sufficient to push frame rates far beyond typical monitor refresh rates. However, the gap between the Low and Ultra presets at 1080p is only 60.4 fps (330.7 vs 270.3), which hints that the CPU is starting to feel the pressure of higher settings, though it still delivers exceptional performance. The single-core performance, evidenced by a Cinebench R23 score of 2,365 and a Geekbench single-core score of 1,933, appears to be the more critical factor for this game’s responsiveness, as Doom does not heavily scale with more than a few threads.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4090 is the undisputed heavyweight in this pairing, a behemoth with 24 GB of GDDR6X memory on a 384-bit bus, yielding a bandwidth of 1.01 TB/s. Its boost clock is 2520 MHz, and it houses 16,384 shading units. This GPU is in the 91st percentile of all graphics cards, with an average benchmark score of 66,473.

The RTX 4090’s nearest rivals, based on average score, include the NVIDIA Tesla T4 (avg score 66,733, deltaPct -0.4) and the NVIDIA Quadro P6000 (avg score 67,320, deltaPct -1.3). These comparisons are misleading in a gaming context, as those are professional compute cards. The sheer GPU compute power, measured at 82.58 TFLOPS for FP32, is overwhelming for Doom, a title from 2016. The data indicates that the GPU is rarely the limiting factor. Even at 4K Ultra, which is the most demanding setting in the measured data, the card still produces an average of 94.7 fps. The 24 GB VRAM is far more than Doom can utilize, meaning memory capacity is a non-issue. The GPU’s ability to render frames is so high that the system’s overall performance is almost entirely dictated by the CPU’s ability to keep up, particularly at lower resolutions where the GPU has spare capacity to render more frames than the CPU can request.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data across resolutions provides a clear picture of the bottleneck. At 1080p with Low settings, the system achieves 330.7 fps. Moving to 1440p Low drops this to 286.6 fps, a 13.3% decrease. At 4K Low, the average is 157.6 fps, which is a 52.3% drop from the 1080p figure. This scaling pattern is classic for a CPU-bound system at lower resolutions; the GPU is not being fully utilized at 1080p, so the frame rate is capped by the CPU. As resolution increases, the GPU workload grows, and the frame rate begins to fall, but the absolute numbers remain incredibly high.

Looking at the Ultra preset tells a different story. At 1080p Ultra, the average is 270.3 fps. At 1440p Ultra, it falls to 171.2 fps (a 36.7% drop), and at 4K Ultra, it reaches 94.7 fps (a 65% drop from 1080p). The larger percentage drop at higher settings indicates that the GPU is becoming more of a factor. The RTX 4090 is powerful, but the demands of 4K Ultra are significant. The data suggests that at 1080p and 1440p, the Ryzen 5 5600G is the primary limiter, preventing the RTX 4090 from reaching its full potential. At 4K, the balance shifts, and the GPU’s rendering load becomes the more dominant constraint, though the CPU still plays a role in preventing higher frame rates.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of the AMD Ryzen 5 5600G and NVIDIA GeForce RTX 4090 holds a rank of 81 out of 1,681 tested combos in Doom. This places it in the top 5% of all configurations in the database, which is an impressive feat on the surface. The high rank is almost entirely attributable to the RTX 4090’s immense power. The data shows that the GPU is capable of producing playable frame rates at 4K Ultra, a feat that very few other cards could match.

However, the rank also reveals the CPU's drag. A system with a more powerful, modern CPU paired with the same RTX 4090 would almost certainly rank higher, as it would not suffer from the same CPU bottleneck at lower resolutions. The 5600G, while competent, is not in the same performance tier as the GPU. The 81st rank suggests that there are 80 other combinations that achieve higher average frame rates across the tested scenarios. This is primarily due to those combos having a CPU that can better feed the RTX 4090, allowing it to stretch its legs at 1080p and 1440p. The data implies a significant imbalance: the GPU is a top-tier part, but the CPU holds the system back from being one of the absolute best performers in the database.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured average FPS, the optimal preset depends heavily on the target resolution and refresh rate. At 1080p, all presets deliver astronomical frame rates, from a low of 270.3 fps on Ultra to a high of 330.7 fps on Low. The difference between Medium and Low is minimal (319 fps vs 330.7 fps), so for competitive play on a high-refresh monitor, the Low preset is the best choice to maximize frame rate. For a visually richer experience, the Ultra preset still provides a superb 270.3 fps, which is far beyond the needs of any standard 1440p or 4K monitor.

At 1440p, the story is similar. The Low preset yields 286.6 fps, while Ultra provides 171.2 fps. Both are excellent for gaming. The High preset at 210 fps is a strong middle ground, offering a good balance of visual fidelity and performance. For 4K, the choice becomes more critical. The Low preset achieves 157.6 fps, which is suitable for high-refresh 4K gaming. The High preset at 115.6 fps is also very playable. The Ultra preset, at 94.7 fps, is the only one that dips below the 100 fps mark, but it is still perfectly smooth for a 4K experience on a 60Hz or even a 120Hz display. The data suggests that to get the most out of this combo, players should prioritize the Low or High preset for maximum frame rates, while the Ultra preset is only recommended for those who prioritize visual quality over the highest possible FPS.
