Doom

The AMD Ryzen 5 9600X and NVIDIA GeForce RTX 2060 combination delivers a playable but decidedly mixed experience in Doom, with performance that scales predictably with resolution and settings. At 1080p, the combo is capable of high refresh rates, but the GPU becomes the clear limiting factor as pixel count increases. The data shows a system where the modern 6-core CPU has ample headroom, while the older Turing-based graphics card struggles to maintain smooth frame rates at 4K.

Resolution Scaling

The measured frame rates reveal a steep performance cliff as resolution increases, a pattern that strongly indicates the RTX 2060 is the primary bottleneck. At 1080p with High settings, the combo averages 128.6 FPS, which drops to 82.6 FPS at 1440p and further to 46.2 FPS at 4K. This represents a 64% reduction in frame rate from 1080p to 4K, a substantial loss that points directly at the GPU's rendering limits rather than any CPU constraint.

The scaling behavior is consistent across all four settings presets. At Low settings, the system produces 178.1 FPS at 1080p, 112.3 FPS at 1440p, and 62.1 FPS at 4K. The 4K Low figure is particularly telling: even with the lowest graphical load, the GPU can only muster 62.1 FPS, suggesting that the RTX 2060's raw throughput is insufficient for 4K gaming regardless of visual complexity. The gap between 1440p and 4K is consistently large, with the latter resolution exacting a roughly 45% performance penalty across all settings.

The resolution scaling pattern shows diminishing returns when moving from 1080p to 1440p, with a 35.8% frame rate drop at High settings, but a more severe 44.1% drop when moving from 1440p to 4K. This non-linear degradation is typical of a GPU that is running out of pixel fillrate and memory bandwidth at higher resolutions. The RTX 2060's 336.0 GB/s memory bandwidth and 192-bit bus width are simply not sufficient for 4K workloads in this game, even with the efficient id Tech engine that Doom uses.

GPU Role

The NVIDIA GeForce RTX 2060 is the decisive component in this pairing, and its specifications explain the measured results. Built on the 12 nm TU106 chip with 1920 shading units, 120 TMUs, and 48 ROPs, the card operates at a base clock of 1365 MHz and a boost of 1680 MHz. The 6 GB of GDDR6 memory on a 192-bit bus provides 336.0 GB/s of bandwidth, which is adequate for 1080p and 1440p but becomes a limiting factor at 4K.

The GPU's benchmark scores place it in the 58th percentile of all GPUs, with an average benchmark score of 16074. Its nearest rivals include the AMD Radeon RX 7600S, which scores 15996 and is 0.5% slower, and the AMD Radeon Pro 5600M, which scores 16351 and is 1.7% faster. These close margins indicate that the RTX 2060 sits in a narrow performance band, and its age shows in demanding scenarios.

The measured frame rates align with the GPU's capabilities. At 1080p High, the 128.6 FPS average suggests the GPU is keeping up with the CPU's output, but the 4K High result of 46.2 FPS falls below the 60 FPS threshold that most users consider the minimum for smooth gameplay. The GPU's 6 GB memory capacity is also a concern at 4K, where texture data can exceed this limit, potentially causing stuttering or texture pop-in, though the measured data shows consistent averages without reported minimums.

CPU Role

The AMD Ryzen 5 9600X is a modern 6-core, 12-thread processor based on the Zen 5 architecture, built on TSMC's 4 nm process. With a base clock of 3.90 GHz and a boost clock of 5.40 GHz, it delivers strong single-threaded performance that is well-suited for Doom's engine. The CPU's benchmark results confirm its capability: it scores 3603 in Cinebench R23 single-core and 25525 in multi-core, placing it in the 85th percentile of all CPUs.

The CPU's nearest rivals in average benchmark score include the Intel Core i5-13490F at 28173 (0.3% slower) and the AMD Ryzen 7 8845HS at 28369 (0.4% faster). These close margins suggest the 9600X is competitive with mid-range and even some higher-tier processors, providing ample headroom for gaming workloads.

In this Doom configuration, the CPU is not the bottleneck at any resolution. The evidence is clear: frame rates drop dramatically with resolution increases, which would not happen if the CPU were the limiting factor. At 1080p Low, the system achieves 178.1 FPS, a figure that is likely near the engine's upper limits and suggests the CPU can feed the GPU faster than the GPU can render. Even at 4K Low, the 62.1 FPS result is more than double the 4K Ultra figure of 39.7 FPS, indicating that the GPU's workload, not CPU processing, determines the final output.

The 32 MB of shared L3 cache and 89.6 GB/s memory bandwidth provide sufficient data throughput for Doom's fast-paced action. The CPU's 3DMark scores, including 1253 in single-thread and 7590 in max threads, show a processor that can handle both the game's physics and AI calculations without straining. The data indicates that upgrading the GPU would yield far greater performance gains than upgrading the CPU in this pairing.

Settings Recommendations

The measured data provides clear guidance on the optimal settings for this combination. At 1080p, all settings presets deliver playable frame rates, with Low at 178.1 FPS, Medium at 153.1 FPS, High at 128.6 FPS, and Ultra at 108 FPS. The jump from High to Ultra costs 20.6 FPS, a 16% reduction, which may not justify the visual improvements for competitive play. For most users, High at 1080p offers the best balance, providing 128.6 FPS while maintaining good visual quality.

At 1440p, the options become more constrained. High settings produce 82.6 FPS, which is smooth for most players, while Ultra drops to 66.9 FPS. Medium at 100.9 FPS is the best choice for users who prioritize frame rate over visual fidelity. Low at 112.3 FPS is unnecessary unless chasing maximum refresh rates, as the visual quality loss is significant.

At 4K, the situation is challenging. The best result is Low at 62.1 FPS, which barely clears the 60 FPS threshold. Medium drops to 55.2 FPS, High to 46.2 FPS, and Ultra to 39.7 FPS. None of these are ideal for a fast-paced FPS, but Low provides the only consistently playable experience. The data suggests that 4K gaming with this GPU is not recommended, and users should either drop to 1440p or consider a GPU upgrade.

The diminishing returns between Medium and High at each resolution are notable. At 1080p, the difference is 24.5 FPS; at 1440p, it is 18.3 FPS; and at 4K, it is 9 FPS. This pattern suggests that High settings offer the best visual-per-frame-rate ratio, while Ultra provides marginal improvements at a significant performance cost.

How This Combo Ranks

In the database of tested combinations, this pairing ranks 1335 out of 1681 combos for Doom, placing it in the bottom 21% of all systems tested. This low ranking is primarily attributable to the RTX 2060, which is an older GPU with limited 4K capabilities. The CPU's strong performance cannot compensate for the GPU's shortcomings at higher resolutions.

The ranking reflects the overall gaming experience across all tested resolutions and settings. While the combo excels at 1080p, where it can push well over 100 FPS on most presets, its performance at 1440p and 4K drags down the aggregate score. Users who primarily play at 1080p will find this system more than adequate, but those who expect 1440p or 4K performance will be disappointed.

The discrepancy between the CPU's 85th percentile ranking and the GPU's 58th percentile ranking highlights the imbalance in this pairing. The Ryzen 5 9600X is a current-generation processor with excellent single-threaded performance, while the RTX 2060 is a previous-generation GPU that was mid-range at launch. This mismatch means the system is not well-balanced for higher resolutions, and the data confirms that the GPU is the limiting factor in most scenarios.

For users considering this combination, the ranking suggests that 1080p gaming is the sweet spot, with the system capable of delivering high refresh rates on High settings. At 1440p, the experience is acceptable but not exceptional, and at 4K, the system falls below the standards expected for modern gaming. The data indicates that this pairing is best suited for competitive or casual gaming at 1080p, where its strengths are most apparent.
