Doom

Resolution Scaling

The measured FPS data for Doom with the AMD Ryzen 5 5600G and AMD Radeon RX 7600 reveals a clear pattern: the RX 7600 is the dominant component in this pairing, with performance scaling almost entirely tied to resolution and settings. Moving from 1920x1080 to 3840x2160 at High settings drops the average frame rate from 75 FPS to 57 FPS, a 24% reduction. At Low settings, the same resolution jump sees a more dramatic fall from 130 FPS to 98 FPS, a 24.6% decrease. This consistent scaling behavior across settings indicates that the GPU is the limiting factor at higher resolutions, while the CPU maintains sufficient headroom.

The most telling data point comes from the Medium settings tier, where the frame rate at 3840x2160 (61 FPS average) is only slightly below the 2560x1440 result (72 FPS) and the 1920x1080 result (81 FPS). This compression of performance at Medium settings suggests that the RX 7600’s 8 GB GDDR6 memory and 128-bit bus width are being taxed more heavily at 4K, but not to the point of collapse. The 288.0 GB/s bandwidth is adequate for Doom’s 2016 engine at this resolution, though the 57 FPS High result at 4K shows the card is approaching its limits.

At Low settings, the scaling is linear and predictable: 130 FPS at 1080p, 116 FPS at 1440p, and 98 FPS at 4K. These numbers indicate that the CPU can feed the GPU adequately even at lower resolutions, where frame rates exceed 100 FPS. The Ryzen 5 5600G’s 6 cores and 12 threads, running at a base clock of 3.90 GHz and boost of 4.40 GHz, are sufficient to avoid bottlenecking the RX 7600 in Doom’s id Tech 6 engine, which is known for its efficient multi-threading.

The Ultra settings results tell a different story. At 3840x2160 Ultra, the average FPS drops to 47, which is below the 60 FPS threshold for smooth gameplay. At 2560x1440 Ultra, the average is 56 FPS, and at 1920x1080 Ultra, it reaches 62 FPS. The gap between High and Ultra at each resolution is significant: 10 FPS at 1080p, 11 FPS at 1440p, and 10 FPS at 4K. This suggests that Ultra presets push the RX 7600’s 2048 shading units and 64 ROPs to their limits, with the 169.9 GPixel/s pixel rate becoming a bottleneck.

CPU Role

The AMD Ryzen 5 5600G is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Cezanne, manufactured on TSMC’s 7 nm process node. Its base clock of 3.90 GHz and boost clock of 4.40 GHz provide solid single-threaded performance, as evidenced by the Cinebench R23 single-core score of 1409 and Geekbench single-core score of 1801. In Doom, a game that scales well with multiple threads, the CPU’s multi-threaded capabilities are reflected in the Cinebench R23 multi-core score of 10551 and Geekbench multi-core score of 8428.

The L3 cache is 16 MB, which is shared across all cores, and the L1 and L2 caches are 64 KB and 512 KB per core respectively. This cache hierarchy is well-suited for gaming workloads, providing fast access to frequently used data. The CPU’s memory bandwidth is 51.2 GB/s through dual-channel DDR4, which is sufficient to feed the RX 7600’s 288.0 GB/s bandwidth without creating a bottleneck.

The CPU’s percentile rank of 74 versus all CPUs indicates it performs better than 74% of all processors tested. Its nearest rivals in terms of average benchmark score include the Intel Core i3-1220P (0.1% difference), Intel Core Ultra 7 256V (-0.1%), and AMD Ryzen 5 7530U (-0.2%). This places the 5600G in a competitive mid-range position, but its performance in Doom is more than adequate given the measured frame rates.

The CPU’s integrated Radeon Vega 7 graphics are not used in this configuration, as the discrete RX 7600 handles all rendering. The 5600G’s TDP of 65 W and PCIe Gen 3 interface (16 lanes) are adequate for this pairing, though the RX 7600 uses PCIe 4.0 x8, which means the CPU’s Gen 3 support could theoretically limit bandwidth in some scenarios. However, the measured FPS data suggests no such limitation in Doom, as frame rates remain high across all resolutions.

Measured FPS Breakdown

At 1920x1080, the measured average frame rates are as follows: Low settings deliver 130 FPS, Medium delivers 81 FPS (with a range of 69 to 93 FPS), High delivers 75 FPS, and Ultra delivers 62 FPS. The 1080p results show a clear tier system, with Low being nearly double the frame rate of Ultra. The Medium settings result is notable for its consistency, with a narrow 24 FPS range between minimum and maximum.

Moving to 2560x1440, the average FPS drops across all settings: Low delivers 116 FPS, Medium delivers 72 FPS (range 61 to 83), High delivers 67 FPS, and Ultra delivers 56 FPS. The percentage drop from 1080p to 1440p is 10.8% for Low, 11.1% for Medium, 10.7% for High, and 9.7% for Ultra. This consistent 10% reduction indicates that the GPU is scaling predictably with pixel count, and the CPU is not introducing any additional variability.

At 3840x2160, the averages are: Low delivers 98 FPS, Medium delivers 61 FPS (range 52 to 71), High delivers 57 FPS, and Ultra delivers 47 FPS. The drop from 1440p to 4K is more pronounced for lower settings: Low sees a 15.5% decrease, Medium a 15.3% decrease, High a 14.9% decrease, and Ultra a 16.1% decrease. This slightly larger percentage drop at 4K indicates that the RX 7600’s memory bandwidth and fill rate are becoming limiting factors at higher pixel counts.

The only settings tier with complete min/max data is Medium, which provides the most detailed picture of frame time consistency. At 1080p Medium, the system maintains a minimum of 69 FPS, ensuring smooth gameplay. At 1440p Medium, the minimum is 61 FPS, which is still above the 60 FPS threshold. At 4K Medium, the minimum is 52 FPS, which may cause noticeable stutter in fast-paced scenarios.

GPU Role

The AMD Radeon RX 7600 is built on the RDNA 3.0 architecture, codenamed Hotpink Bonefish, with the Navi 33 chip manufactured on TSMC’s 6 nm process node. Its 2048 shading units, 128 TMUs, and 64 ROPs deliver a FP32 performance of 21.75 TFLOPS and a texture rate of 339.8 GTexel/s. The pixel rate of 169.9 GPixel/s is a key figure for Doom, as the game’s fast-paced rendering demands high fill rates.

The GPU’s 8 GB of GDDR6 memory on a 128-bit bus provides 288.0 GB/s of bandwidth, which is the primary constraint at 4K resolutions. The memory runs at an effective 18 Gbps, and the card’s base clock is 1720 MHz with a boost clock of 2655 MHz and a game clock of 2250 MHz. These clock speeds are typical for the RX 7000 series, and the 165 W TDP is managed through a single 8-pin power connector.

The GPU’s percentile rank of 57 versus all GPUs places it in the lower-middle range of graphics cards. Its average benchmark score is 15171, which is 0.2% below the NVIDIA GeForce RTX 3050 OEM (15199) and 0.7% below the AMD Radeon 680M (15270). The RX 7600 outperforms the AMD Radeon Pro 560X by 0.6% and the NVIDIA GeForce GTX 660 Ti by 0.7%. These rival comparisons highlight the RX 7600’s position as a mid-range card that can handle Doom at high settings but not at maximum quality in 4K.

In Doom specifically, the GPU’s DirectX 12 performance is shown in the PassMark DirectX 12 score of 58, which is lower than its DirectX 11 score of 172. This suggests the card is better optimized for older APIs, which is relevant for a 2016 game that supports Vulkan. The Vulkan score of 34401 in Geekbench indicates strong Vulkan performance, which Doom can leverage for improved frame rates.

Settings Recommendations

Based on the measured FPS data, the optimal experience for this system is at 1920x1080 with Medium settings, which delivers an average of 81 FPS with a minimum of 69 FPS. This combination provides a 60+ FPS floor with room for spikes up to 93 FPS, ensuring smooth gameplay without sacrificing too much visual quality. The Medium preset at 1080p is the sweet spot for consistent performance.

For players prioritizing frame rate over visuals, 1920x1080 Low settings deliver an average of 130 FPS, which is ideal for competitive play. This setting ensures the highest possible refresh rate utilization, though it sacrifices shadow quality and texture detail. The 1080p Low result is nearly double the frame rate of 1080p Ultra, making it the clear choice for esports-style play.

At 2560x1440, Medium settings are recommended, delivering an average of 72 FPS with a minimum of 61 FPS. This provides a playable experience at higher resolution, though the frame rate floor is close to the 60 FPS threshold. The 1440p High setting (67 FPS average) is also viable, but the lack of min/max data makes Medium the safer choice for guaranteed stability.

The 4K resolution is best avoided for this hardware. Even at Medium settings, the average FPS is 61, but the minimum of 52 FPS indicates potential stuttering. The 4K High setting (57 FPS) and 4K Ultra (47 FPS) fall below the 60 FPS threshold, making them unsuitable for smooth gameplay. If 4K is required, Low settings at 98 FPS is the only option that maintains high frame rates.

The Ultra preset is not recommended at any resolution. At 1080p Ultra, the average is 62 FPS, which is playable but leaves little headroom. At 1440p Ultra, the average drops to 56 FPS, and at 4K Ultra, it falls to 47 FPS. The jump from High to Ultra costs 10-11 FPS at each resolution, which is a significant penalty for marginal visual improvements. The data clearly shows that Medium settings offer the best balance of performance and visual quality across all resolutions.
