Doom

The AMD Ryzen 5 2600 paired with the NVIDIA GeForce RTX 4080 produces a surprisingly balanced 1080p experience in Doom, but the data clearly shows that the CPU becomes a bottleneck at lower resolutions while the GPU dominates at 4K. At 1080p Ultra, the combo delivers 196 FPS, which is high, yet the gap between Low and Ultra settings at that resolution is only 38 FPS, suggesting the processor limits frame rates more than the graphics card. Moving to 4K, the Ultra preset drops to 85 FPS, a 111 FPS decline from 1080p, indicating that the RTX 4080 is doing the heavy lifting at higher pixel counts. This combination ranks 814th out of 3712 tested combos, placing it in the top 22% of all pairings.

GPU Role

The NVIDIA GeForce RTX 4080 is the dominant component in this pairing, particularly at higher resolutions. The GPU has 16 GB of GDDR6X memory on a 256-bit bus, delivering 716.8 GB/s of bandwidth. Its base clock is 2205 MHz, with a boost clock of 2505 MHz. The data shows that the GPU's capabilities are most evident at 4K resolution, where the average FPS across all settings ranges from 85 at Ultra to 141 at Low. The RTX 4080's high pixel rate of 280.6 GPixel/s and texture rate of 761.5 GTexel/s are directly reflected in these results, as the card is able to maintain high frame rates even with demanding 4K workloads.

The benchmark scores for the RTX 4080 reinforce its position as a top-tier GPU. It achieves a Passmark G3D score of 34457 and a Geekbench Vulkan score of 263779. Its average benchmark score of 54247 places it in the 86th percentile of all GPUs. Compared to its nearest rival, the RTX 4080 SUPER, it is essentially tied, with a deltaPct of only 0.1%. This suggests that in Doom, the RTX 4080's performance is not limited by its own architecture, but rather by the CPU at lower resolutions. The GPU's 9728 shading units and 112 ROPs allow it to process the game's geometry and effects efficiently, which is why the 4K results show a clear scaling pattern from Low to Ultra settings.

Resolution Scaling

The FPS data reveals a classic pattern of scaling that points to the CPU as the limiting factor at 1080p and the GPU at 4K. At 1920x1080, the average FPS across all settings is remarkably close: Low delivers 234 FPS, Medium 223 FPS, High 210 FPS, and Ultra 196 FPS. The maximum spread between Low and Ultra at 1080p is just 38 FPS, which is a relatively small difference. This indicates that the Ryzen 5 2600 cannot feed the RTX 4080 enough frames to push higher, as the GPU is capable of much more at this resolution.

Moving to 2560x1440, the scaling becomes more pronounced. Low settings hit 203 FPS, Medium 193 FPS, High 182 FPS, and Ultra 156 FPS. The gap between Low and Ultra at 1440p is 47 FPS, a larger spread than at 1080p, showing that the GPU is starting to become more relevant. At 3840x2160, the scaling is dramatic: Low delivers 141 FPS, Medium 123 FPS, High 104 FPS, and Ultra 85 FPS. The difference between Low and Ultra at 4K is 56 FPS, and the overall drop from 1080p Low to 4K Low is 93 FPS. This steep decline at 4K confirms that the RTX 4080 is the primary driver of performance at this resolution, as the GPU's compute and memory resources are fully engaged.

How This Combo Ranks

The combination of the AMD Ryzen 5 2600 and NVIDIA GeForce RTX 4080 ranks 814th out of 3712 tested combos in Doom. This places the pairing in the top 21.9% of all configurations, which is a strong result given the age of the CPU. The rank reflects the fact that the RTX 4080 is a high-end GPU, but the Ryzen 5 2600, with its 6 cores and 12 threads, is a mid-range processor from 2018. The data shows that the combo's overall standing is dragged down by the CPU's inability to keep pace at lower resolutions, where the frame rates are already high but could be even higher with a newer processor.

The CPU's average benchmark score is 21484, which is only 0.2% higher than the Intel Core Ultra 5 228V and 0.5% higher than the Intel Core i9-11900H. This suggests that the Ryzen 5 2600 is competitive with those chips in general workloads, but in gaming, the single-thread performance is what matters most. The CPU's Geekbench single-core score of 1154 is modest, and this is reflected in the 1080p results where the frame rates plateau. Despite this, the combo still ranks well because the RTX 4080's raw power ensures playable frame rates at all resolutions, and the 4K results are particularly strong.

CPU Role

The AMD Ryzen 5 2600 is a 6-core, 12-thread processor based on the Zen+ architecture, manufactured on a 12 nm process. It has a base clock of 3.40 GHz and a boost clock of 3.90 GHz. The CPU's 16 MB of shared L3 cache and dual-channel DDR4 memory support with 46.9 GB/s bandwidth are adequate for gaming, but its single-thread performance is the limiting factor in Doom. The CPU's Passmark single-thread score of 2239 and Geekbench single-core score of 1154 are modest by modern standards, which explains why the 1080p frame rates do not scale as much as the GPU's capabilities would allow.

In Doom, the CPU's role is most apparent in the 1080p results, where the average FPS stays within a narrow band of 196 to 234 FPS across all settings. This is because the game's engine relies heavily on the CPU to process game logic and draw calls, and the Ryzen 5 2600's 6 cores are sufficient to handle this, but the clock speed limits the maximum frame rate. The CPU's multi-threaded performance, with a Cinebench R15 multicore score of 1248 and a Passmark multithread score of 13160, suggests it can handle the game's background tasks, but the single-thread bottleneck is clear. At 4K, the CPU's impact is minimized because the GPU becomes the bottleneck, and the frame rates are more dependent on the RTX 4080's fill rate and memory bandwidth.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across resolutions and settings. At 1920x1080, the combo delivers 234 FPS on Low, 223 FPS on Medium, 210 FPS on High, and 196 FPS on Ultra. The Medium setting has a recorded minimum of 190 FPS and a maximum of 257 FPS, indicating some variability but overall smooth performance. At this resolution, the frame rates are consistently above 190 FPS, which means the game is highly playable, but the CPU is clearly the limiting factor, as the differences between settings are small.

At 2560x1440, the results show 203 FPS on Low, 193 FPS on Medium, 182 FPS on High, and 156 FPS on Ultra. The Medium setting's minimum is 164 FPS and maximum is 222 FPS. The drop from 1080p to 1440p is noticeable, especially at Ultra, where the frame rate falls by 40 FPS. This indicates that the GPU is beginning to take on more work, but the CPU still has some headroom. At 3840x2160, the frame rates are 141 FPS on Low, 123 FPS on Medium, 104 FPS on High, and 85 FPS on Ultra. The Medium setting at 4K has a minimum of 104 FPS and a maximum of 141 FPS. The 4K Ultra result of 85 FPS is still above the 60 FPS threshold for smooth gameplay, but it is a significant drop from the 196 FPS at 1080p Ultra, showcasing the GPU's workload at high pixel counts.
