Doom

The AMD Ryzen 5 4600G paired with the AMD Radeon RX 7600 XT delivers a compelling 1080p experience in Doom, but the data reveals a clear shift in bottleneck behavior as resolution climbs. At 1920x1080 with Low settings, the combo produces 198 FPS average, but this drops to 145.5 FPS at High and 119.4 FPS at Ultra. The scaling from Low to Ultra at 1080p shows a 78.6 FPS swing, indicating that the GPU is increasingly stressed by higher graphical fidelity. Moving to 2560x1440, the frame rate at Low is 127.6 FPS, which falls to 75.6 FPS at Ultra—a tighter relative drop that suggests the CPU still has headroom but the graphics card is now doing heavier lifting. At 3840x2160, the picture changes decisively: Low yields 70.5 FPS, Medium 58.7 FPS, High 51.6 FPS, and Ultra plunges to 41.9 FPS. The 4K results show a 28.6 FPS difference between Low and Ultra, meaning the RX 7600 XT becomes the limiting factor at this resolution, while the Ryzen 5 4600G’s six cores and 12 threads are sufficient to feed it.

Resolution Scaling

The frame rate curve across resolutions tells a story of a balanced pairing at 1440p and below, with the GPU taking over as the primary constraint at 4K. At 1080p Low, the combo hits 198 FPS, which is nearly triple the 4K Ultra result of 41.9 FPS. This 156.1 FPS gap highlights how dramatically resolution impacts the workload. The 1440p results sit comfortably in between: Low produces 127.6 FPS, a 70.4 FPS reduction from 1080p Low, while 1440p Ultra at 75.6 FPS is 43.8 FPS lower than its 1080p counterpart. The data indicates that the RX 7600 XT, with its 16 GB of GDDR6 memory and 288.0 GB/s bandwidth, is not the bottleneck until 4K, where the pixel throughput demands exceed what the card can deliver. At 1080p, the Ryzen 5 4600G’s boost clock of 4.20 GHz and 8 MB of shared L3 cache are adequate to maintain high frame rates, but the GPU’s 22.57 TFLOPS FP32 performance becomes the ceiling at higher resolutions.

How This Combo Ranks

In the context of all tested combinations for Doom, this pairing ranks 1116 out of 1681 combos. That places it in the lower-middle tier of the database, which is consistent with the component choices: the CPU sits at the 75th percentile versus all CPUs, while the GPU is at the 63rd percentile versus all GPUs. The combo’s rank suggests that while it handles 1080p well, it is not a top-tier setup for 4K gaming. The Ryzen 5 4600G’s nearest rivals include the AMD Ryzen 3 PRO 5355GE (matching average score) and the Intel Core i3-14100T, which is 0.8% faster in average benchmark score. The RX 7600 XT’s nearest rivals show it is closely matched with the RX 7600 (0.6% slower) and the RTX 2060 SUPER (1.9% faster). These deltas are small, meaning the combo’s rank is driven more by the CPU’s modest single-thread performance—its 3DMark single-thread score is 726—than by any GPU deficiency. For a game like Doom, which leans on high frame rates, the rank indicates this is a solid 1440p machine, but not a 4K powerhouse.

GPU Role

The AMD Radeon RX 7600 XT is the defining component in this pairing, particularly because of its 16 GB GDDR6 memory on a 128-bit bus, yielding 288.0 GB/s of bandwidth. This memory capacity is generous for a 2016 title like Doom, and the data shows it is not a limiting factor even at 4K Ultra. The GPU’s clocks are notable: a base of 1980 MHz, a game clock of 2470 MHz, and a boost of 2755 MHz. These clocks, combined with 32 ray accelerators and 64 ROPs, produce a pixel rate of 176.3 GPixel/s and a texture rate of 352.6 GTexel/s. In practice, these specs translate to the frame rates seen: at 1080p Ultra, the card sustains 119.4 FPS, but at 4K Ultra, it falls to 41.9 FPS. The GPU’s PassMark G3D score of 17132 and its 3DMark Steel Nomad DX12 score of 2348 place it above the 63rd percentile of all GPUs, but the 4K results show that even 16 GB of VRAM cannot overcome the raw compute demands. The GPU’s 190 W TDP and PCIe 4.0 x8 interface are adequate, but the data confirms that the RX 7600 XT is the component that dictates performance ceilings at 1440p and above.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings produce 198 FPS average, Medium yields 174.1 FPS, High drops to 145.5 FPS, and Ultra bottoms out at 119.4 FPS. These numbers show a 78.6 FPS spread from Low to Ultra, indicating that the GPU is handling the load with ease, and the CPU is not a limiting factor—the 1080p Low result is over 50 FPS higher than the 1440p Low result of 127.6 FPS. Moving to 2560x1440, the frame rates are still respectable: Low sits at 127.6 FPS, Medium at 112.7 FPS, High at 97.3 FPS, and Ultra at 75.6 FPS. The 51.9 FPS difference between Low and Ultra at 1440p is proportionally smaller than at 1080p, which signals the GPU is beginning to struggle with higher settings. At 3840x2160, the results are more modest: Low achieves 70.5 FPS, Medium drops to 58.7 FPS, High to 51.6 FPS, and Ultra to 41.9 FPS. The 28.6 FPS gap between Low and Ultra at 4K is the smallest absolute spread, confirming that the GPU is the primary bottleneck—the CPU’s 51.2 GB/s memory bandwidth and Zen 2 architecture are sufficient, but the RX 7600 XT’s 2048 shading units cannot keep pace with 4K pixel counts.
