Doom

The AMD Ryzen 5 8400F and AMD Radeon RX 7600 combination delivers a playable experience across most settings in Doom, though the data reveals a clear performance ceiling that shifts depending on resolution. The measured results show a system capable of high refresh rates at 1080p but one that becomes progressively more constrained as pixel count increases.

Resolution Scaling

The frame rate curve from 1080p to 4K demonstrates classic GPU-bound behavior, with the most dramatic drop occurring at the highest resolution. At 1080p with Ultra settings, the combo produces 118.6 FPS, but this falls to 76.6 FPS at 1440p and further to 39.2 FPS at 4K. The scaling pattern indicates that the RX 7600 becomes the limiting factor as resolution increases, while the Ryzen 5 8400F provides ample headroom at lower resolutions.

The gap between Low and Ultra settings widens substantially at higher resolutions. At 1080p, the difference between Low (196 FPS) and Ultra (118.6 FPS) is 77.4 FPS, a 65% performance spread. At 1440p, that spread narrows to 50.1 FPS (126.7 vs 76.6), and at 4K it compresses to 31.4 FPS (70.6 vs 39.2). This tightening suggests that at 4K, the GPU is saturated even at Low settings, leaving less room for settings-based performance differentiation.

The 4K results tell a particularly telling story. Medium settings at 4K yield 57.9 FPS, while High settings produce 52.9 FPS — a modest 5 FPS penalty. However, jumping to Ultra at 4K costs 13.7 FPS compared to High, dropping the experience to 39.2 FPS, which falls below the smoothness threshold many players target. The data indicates that 4K Ultra is the point where this combination begins to struggle, while 4K Medium remains viable for those willing to compromise on visual fidelity.

At 1440p, the combo shows stronger performance characteristics. Low settings reach 126.7 FPS, Medium hits 110.5 FPS, and even Ultra maintains 76.6 FPS. The 1440p results suggest that this resolution represents the sweet spot for balancing visual quality and frame rate, with High settings at 94.5 FPS offering a particularly attractive middle ground.

GPU Role

The RX 7600's 8 GB of GDDR6 memory on a 128-bit bus with 288.0 GB/s bandwidth proves adequate for Doom's demands, though the data suggests capacity and bandwidth constraints emerge at higher resolutions. The GPU's boost clock of 2655 MHz and game clock of 2250 MHz contribute to its compute capabilities, with the card delivering 21.75 TFLOPS of FP32 performance. These specifications position the card solidly within the mid-range segment, as evidenced by its 63rd percentile ranking among all GPUs.

The GPU's benchmark profile shows strong DirectX 11 performance with a Passmark score of 172, while DirectX 12 scores 58 and DirectX 9 reaches 226. The Geekbench Vulkan score of 90825 indicates respectable API-level performance for a modern title like Doom. In terms of nearest rivals, the RX 7600 sits within 1.5% of several competitors: it trails the Intel Arc B570 by 1.5%, lags the NVIDIA GeForce RTX 3070 Mobile by 1.3%, and edges out the AMD Radeon RX 460 by 0.8% and the RX 7600 XT by 0.6% in average benchmark scores.

The VRAM allocation becomes a critical factor at 4K Ultra, where the 39.2 FPS result likely reflects both compute and memory pressure. The 8 GB frame buffer, while standard for this class, shows its limitations when pushed to maximum settings at 3840x2160. At 1080p, the GPU's resources are sufficient to maintain high frame rates across all settings, with even Ultra exceeding 118 FPS.

FAQ

Q: What is the best resolution for this combo in Doom?

A: The data shows 1440p offers the best balance, with Low settings reaching 126.7 FPS and Ultra maintaining 76.6 FPS. At 4K, Ultra drops to 39.2 FPS, while 1080p Ultra stays above 118 FPS.

Q: How much performance is lost when moving from 1080p to 4K at Ultra settings?

A: The average frame rate drops from 118.6 FPS at 1080p Ultra to 39.2 FPS at 4K Ultra, representing a 79.4 FPS reduction that makes the 4K experience significantly less smooth.

Q: Does lowering settings from Ultra to Low provide a meaningful boost at 4K?

A: Yes. At 4K, Low settings deliver 70.6 FPS compared to 39.2 FPS at Ultra — an improvement of 31.4 FPS or roughly 80% higher frame rate.

Q: How does the RX 7600 compare to its closest competitor, the RX 7600 XT?

A: In average benchmark scores, the RX 7600 scores 20258 versus the RX 7600 XT's 20146, putting the base model 0.6% ahead despite the XT name.

Q: What CPU benchmark scores support the Ryzen 5 8400F's performance in this combo?

A: The CPU achieves 20851 in Cinebench R23 multi-core and 2943 in single-core, with a Passmark multithread score of 24530 and a single-thread score of 3684.

Q: Is the 4K Ultra setting usable with this hardware?

A: The 39.2 FPS average at 4K Ultra falls below typical smoothness thresholds, making it marginal for fast-paced FPS gameplay. Medium settings at 4K, which produce 57.9 FPS, represent a more viable option.

How This Combo Ranks

Among 1681 tested CPU-GPU combinations, this pairing ranks 1120th in Doom. That places it in the lower third of all tested configurations, which reflects the mid-range positioning of both components. The Ryzen 5 8400F itself ranks in the 82nd percentile among all CPUs, while the RX 7600 sits in the 63rd percentile among all GPUs — the GPU's lower relative standing likely drags down the combo's overall rank.

The CPU's nearest rivals in average benchmark score include the AMD Ryzen 7 2700X (25057, 0% delta), AMD Ryzen AI 5 PRO 340 (25099, -0.1%), AMD EPYC 9474F (25103, -0.2%), and AMD Ryzen 5 7500F (24993, 0.3%). This clustering shows the 8400F performing within a tight band of competitors, suggesting that CPU choice among these options would have minimal impact on Doom performance.

The GPU's competitive landscape shows a similarly tight grouping. The RX 7600's nearest rivals all fall within 1.5% of its average score, indicating that the graphics card market at this tier offers limited performance differentiation. The 0.6% advantage over the RX 7600 XT is particularly notable given the name-based expectation that the XT variant would outperform the base model.

The rank of 1120 out of 1681 indicates that while this combo delivers playable frame rates in Doom, it does not represent a top-tier configuration. Users seeking maximum performance in this title would need to look toward higher-end GPUs, as the data suggests the RX 7600 is the primary bottleneck in this pairing.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results across all settings. Low settings produce 196 FPS, Medium reaches 169.3 FPS, High hits 145.6 FPS, and Ultra maintains 118.6 FPS. Every setting at 1080p exceeds 118 FPS, making this resolution ideal for high refresh rate displays.

The 2560x1440 results show a step down but remain solid. Low settings reach 126.7 FPS, Medium achieves 110.5 FPS, High produces 94.5 FPS, and Ultra drops to 76.6 FPS. The 1440p Ultra figure remains above 60 FPS, providing a smooth experience for most players.

At 3840x2160, the performance envelope tightens considerably. Low settings yield 70.6 FPS, Medium produces 57.9 FPS, High reaches 52.9 FPS, and Ultra falls to 39.2 FPS. The 4K data reveals that only Low settings maintain a frame rate above 60 FPS, while Ultra dips below 40 FPS, highlighting the GPU's limitations at this resolution.

The progression from 1080p to 4K at High settings shows a steady decline: 145.6 FPS at 1080p, 94.5 FPS at 1440p, and 52.9 FPS at 4K. This represents a 36% drop from 1080p to 1440p and a further 44% drop from 1440p to 4K. The scaling pattern confirms that the RX 7600's 8 GB memory configuration and 288.0 GB/s bandwidth become increasingly strained as resolution increases, making 1080p the resolution where this combo performs most comfortably.
