Doom

Resolution Scaling

The measured FPS data for Doom with the AMD Ryzen 7 7700 and AMD Radeon RX 570 shows a steep performance cliff as resolution climbs. At 1920x1080 with High settings, the combo delivers 69.7 FPS average. Moving to 2560x1440 at the same preset drops that figure to 43.7 FPS, a reduction of roughly 37%. The step to 3840x2160 is even more punishing, with High settings yielding just 25.3 FPS average — barely more than a third of the 1080p result. This scaling pattern is characteristic of a GPU-bound scenario. The RX 570's 224.0 GB/s memory bandwidth and 256-bit bus are being saturated as pixel count rises, while the Ryzen 7 7700's 8 cores and 16 threads are not the limiting factor at these resolutions.

The delta between Low and Ultra settings widens noticeably at higher resolutions. At 1080p, the spread from Low (94.3 FPS) to Ultra (58.3 FPS) is 36 FPS. At 1440p, that spread narrows to 24.8 FPS (59.2 FPS Low versus 34.4 FPS Ultra). At 4K, the Low-to-Ultra gap compresses further to 12 FPS (34.3 FPS versus 22.3 FPS). This compression indicates that at 4K, the GPU's raw throughput ceiling — its 5.095 TFLOPS FP32 performance — dominates the frame rate, and settings adjustments cannot overcome the fundamental fill-rate and bandwidth constraints.

The data also reveals that the RX 570's 4 GB GDDR5 frame buffer becomes a limiting factor at 4K. The average FPS at 3840x2160 across all settings sits in the low-to-mid 20s range, with even Low settings only reaching 34.3 FPS. This suggests that memory capacity, not just memory bandwidth, is constraining performance. The 1750 MHz memory clock (7 Gbps effective) provides sufficient throughput for 1080p and most 1440p scenarios, but the jump to 4K demands more capacity than the card can physically hold, causing additional overhead that cannot be mitigated by lowering graphical fidelity.

GPU Role

The AMD Radeon RX 570, built on the Polaris 20 chip with GCN 4.0 architecture at 14 nm, is the decisive component in this pairing. Its base clock of 1168 MHz and boost clock of 1244 MHz set the operational envelope, but the real story is the memory subsystem. With 4 GB of GDDR5 on a 256-bit bus delivering 224.0 GB/s, the card has enough bandwidth for 1080p gaming but struggles as resolution increases. The measured FPS data confirms this: the card's 32 ROPs and 128 TMUs are tasked heavily at 1440p and beyond, and the pixel rate of 39.81 GPixel/s becomes a bottleneck.

The FP32 throughput of 5.095 TFLOPS places this GPU firmly in the mid-range segment, and the benchmark results reflect that positioning. The RX 570's average benchmark score of 30158 places it in the 74th percentile of all GPUs, with nearest rivals including the NVIDIA GeForce RTX 5060 (deltaPct 0.2), AMD Radeon RX 7700 XT (deltaPct 0.2), and NVIDIA Tesla M60 (deltaPct 0.6). These rivals are all within 0.8% of the RX 570's average score, indicating that this card sits at a competitive performance plateau. For Doom specifically, the GPU's DirectX 12 (12_0) support and Vulkan 1.3 capabilities are sufficient, but the 4 GB memory limit is the hard constraint that prevents playable 4K performance.

The Ryzen 7 7700's integrated Radeon Graphics are irrelevant here, as the discrete RX 570 handles all rendering duties. The CPU's 83.2 GB/s memory bandwidth on DDR5 is more than adequate to feed the GPU, and the 5.30 GHz boost clock ensures no CPU-side stalling. Benchmark data for the 7700 shows a Cinebench R23 multicore score of 29302 and a single-core score of 4136, placing it in the 91st percentile of all CPUs. This is a processor with substantial headroom; the measured FPS in Doom is entirely GPU-limited, particularly at 1440p and 4K where the RX 570's architecture is pushed to its limits.

How This Combo Ranks

The combination of the AMD Ryzen 7 7700 with the AMD Radeon RX 570 ranks 1587 out of 1681 tested combos in Doom. This places the pairing in the bottom 6% of all configurations, which is a striking result given that both components individually sit near the 74th to 91st percentiles in their respective categories. The explanation lies in the mismatch between the CPU's capabilities and the GPU's age. The RX 570, released in April 2017, was designed for a different era of gaming demands. Doom, released in May 2016, is contemporary with this GPU, but the card's end-of-life production status and 4 GB memory capacity hold it back in the current benchmark pool.

The rank of 1587 out of 1681 combos indicates that the vast majority of tested systems outperform this pairing in Doom. This is not a reflection of the CPU, which is a current-generation Zen 4 part with 8 cores and 16 threads. Rather, it is the GPU that drags the combo down. The RX 570's nearest rivals in the benchmark database — the RTX 5060, RX 7700 XT, and Tesla M60 — all have average scores within 0.8% of each other, but the measured FPS in Doom tells a more nuanced story. The 4 GB memory limit and 14 nm process node put the RX 570 at a structural disadvantage compared to newer GPUs with larger frame buffers and more efficient architectures.

For context, the Ryzen 7 7700 alone ranks in the 91st percentile of CPUs, with an average benchmark score of 40468. Its nearest rivals include the AMD Ryzen 9 7940H (deltaPct 0.1), AMD Ryzen AI 9 365 (deltaPct 0.5), and Intel Core i9-13905H (deltaPct -0.6). This CPU is more than capable of driving high frame rates in Doom. The bottleneck is unambiguous: the RX 570's 150 W TDP and 5.095 TFLOPS FP32 throughput are simply insufficient for the demands of modern benchmark configurations, even for a game released in 2016.

Measured FPS Breakdown

At 1920x1080, the combo produces playable frame rates across all settings. Low settings yield 94.3 FPS average, Medium drops to 82 FPS, High reaches 69.7 FPS, and Ultra falls to 58.3 FPS. The gap between Low and Ultra is 36 FPS, representing a 38% performance penalty for maximum graphical fidelity. This resolution is where the RX 570 is most comfortable, as the 224.0 GB/s bandwidth is sufficient to feed the 256-bit memory interface without excessive contention.

Moving to 2560x1440, the performance picture changes significantly. Low settings deliver 59.2 FPS average, which is still playable, but Medium drops to 50.5 FPS, High to 43.7 FPS, and Ultra falls to 34.4 FPS. The Low-to-Ultra spread narrows to 24.8 FPS, indicating that the GPU is beginning to hit its throughput ceiling. The 34.4 FPS at Ultra is borderline for a fast-paced FPS like Doom, where smooth motion is critical for gameplay.

At 3840x2160, the results are disappointing but predictable. Low settings manage 34.3 FPS, Medium falls to 26.5 FPS, High reaches 25.3 FPS, and Ultra bottoms out at 22.3 FPS. None of these are playable for a competitive FPS experience. The 4 GB frame buffer is likely causing texture thrashing at this resolution, as Doom's high-resolution textures exceed the available memory. The delta between Low and Ultra is just 12 FPS, showing that settings adjustments have diminishing returns when the GPU is this far past its design point.

The 1080p results are the only ones that approach the 60 FPS target, and even then, only Low and Medium presets clear that bar. High at 69.7 FPS is acceptable, but Ultra at 58.3 FPS dips below the threshold. For 1440p, only Low settings exceed 60 FPS, and just barely at 59.2 FPS. The 4K results are uniformly below 35 FPS, confirming that this combo is not suited for 4K gaming in Doom.

Settings Recommendations

The measured data points to 1920x1080 as the only resolution where this combo delivers a consistently smooth experience. At 1080p, the Medium preset at 82 FPS average offers the best balance of visual quality and performance headroom. It stays well above the 60 FPS threshold while providing better fidelity than Low. The High preset at 69.7 FPS is also viable, but the 12.3 FPS drop from Medium to High is less justifiable when the visual improvement is marginal in a fast-paced title like Doom.

For users who prioritize maximum frame rates, the Low preset at 1080p delivers 94.3 FPS average, which is excellent for competitive play. However, the jump from Low to Medium costs only 12.3 FPS and provides noticeably better textures and effects. Given that the RX 570 has 4 GB of VRAM, Medium settings are likely to fit within the memory budget without causing stuttering from texture swapping.

At 2560x1440, the situation is more constrained. The Low preset at 59.2 FPS is the only option that approaches the 60 FPS target, and it falls just short. Users with 1440p monitors should consider dropping to 1080p for a smoother experience, as the 34.4 FPS at 1440p Ultra is unplayable for a game that demands quick reflexes. The Medium preset at 50.5 FPS is playable but leaves little margin for demanding scenes.

The 4K resolution results are uniformly poor, with the best case being Low at 34.3 FPS. This is below the playability threshold for an FPS, and the data suggests that users should avoid 3840x2160 entirely with this combination. The card's 4 GB memory capacity and 224.0 GB/s bandwidth are insufficient for 4K Doom, regardless of settings. The Ultra preset at 22.3 FPS is particularly telling — it is less than a quarter of the 1080p Low performance, and the settings compression at this resolution confirms that the GPU is the sole limiting factor.
