# Downfall with AMD Ryzen 7 5800XT + Intel Arc B570

The AMD Ryzen 7 5800XT paired with the Intel Arc B570 delivers a playable but resolution-sensitive experience in Downfall, with the combo ranking in the 2343rd position out of 2928 tested combinations. This places the pairing in the lower-middle tier of the database, though the CPU's strong multi-threaded performance suggests the GPU is the primary constraint at higher resolutions. The measured frame rates reveal a system that excels at 1080p and remains viable at 1440p, while 4K Ultra pushes the hardware to its limits with an average of just 30 FPS.

Resolution Scaling

The frame rate progression across resolutions tells a clear story about where the bottleneck sits in this pairing. At 1080p High settings, the combo produces 109 FPS average, which drops to 78 FPS at 1440p High, a 28% reduction, and further to 49 FPS at 4K High, a 37% drop from 1440p. This scaling pattern indicates that the Intel Arc B570's graphics processing power becomes increasingly dominant as pixel count rises, while the Ryzen 7 5800XT has ample headroom to feed frames at lower resolutions.

The Low settings preset highlights the CPU's capability more directly. At 1080p Low, the system reaches 163 FPS average, which is the highest measured result in the entire dataset. Moving to 1440p Low yields 116 FPS (a 29% decrease), and 4K Low produces 72 FPS (a 38% decrease from 1440p). The consistent percentage drops across settings presets suggest that resolution scaling is largely independent of the quality settings chosen, pointing to a GPU that scales predictably with pixel throughput.

Medium settings show the most complete data with minimum and maximum frame times recorded. At 1080p Medium, the average is 133 FPS with a range from 113 to 153 FPS, representing a 15% variance between minimum and maximum. The 1440p Medium result averages 95 FPS with a range of 81 to 110 FPS, showing a 17% variance. At 4K Medium, the average drops to 59 FPS with a range of 50 to 68 FPS, a 18% variance. This increasing variance at higher resolutions indicates that the GPU's frame pacing becomes less consistent as it approaches its throughput ceiling.

Ultra settings present the most demanding scenario and reveal the steepest scaling curve. The system achieves 68 FPS average at 1080p Ultra, 49 FPS at 1440p Ultra, and 30 FPS at 4K Ultra. The jump from 1440p to 4K at Ultra settings represents a 39% performance loss, which is the largest proportional drop across any settings-to-resolution combination in the dataset. This suggests that the Arc B570's 10 GB VRAM buffer and 160-bit memory interface become significant limiting factors when both resolution and texture quality are maximized simultaneously.

How This Combo Ranks

With a combo rank of 2343 out of 2928 tested combinations in Downfall, this pairing sits in the 80th percentile from the bottom, meaning roughly 80% of tested combos perform better in this game. This ranking reflects the Arc B570's position as a mid-range GPU rather than any deficiency in the Ryzen 7 5800XT, which holds an 81st percentile ranking among all CPUs in the database. The disparity between the CPU's strong standing and the combo's modest rank indicates that Downfall is heavily GPU-bound in this configuration.

The GPU's individual percentile ranking of 65 places it above the median for all tested graphics cards, yet the combo rank suggests that Downfall's specific demands may not favor the Arc architecture's strengths. The Intel Arc B570's nearest rivals in synthetic benchmarks include the NVIDIA GeForce RTX 3070 Mobile with a deltaPct of 0.1, the Intel Arc A750 at -0.1, the NVIDIA Quadro M4000M at 0.4, and the AMD Radeon R9 M390X at -0.5. These close margins in average benchmark scores indicate that the B570 performs within 0.5% of these competitors in general compute tasks, though real-world game performance can diverge significantly from synthetic results.

The Ryzen 7 5800XT's nearest rivals show similarly tight clustering, with the AMD Ryzen 7 7840H matching its average score exactly at 0% delta, the AMD Ryzen 7 8845HS and AMD Ryzen 7 7840HS both trailing by 0.3%, and the AMD Ryzen 5 9600X leading by 0.6%. This CPU performance tier is well-established, and the 5800XT's 8-core, 16-thread configuration provides substantial processing power that should not be the limiting factor in most gaming scenarios. The combo's low rank in Downfall therefore points to the GPU as the performance ceiling.

GPU Role

The Intel Arc B570 operates with a fixed clock speed of 2500 MHz for both base and boost, which is notable for a GPU that draws 150 W TDP. The 10 GB of GDDR6 memory runs at 2375 MHz with an effective speed of 19 Gbps, delivering 380.0 GB/s of bandwidth across a 160-bit bus. This memory configuration is adequate for 1080p and 1440p gaming but shows strain at 4K Ultra settings, where the average frame rate drops to 30 FPS and the larger texture sets likely exceed the comfortable VRAM headroom.

The GPU's compute capabilities include 2304 shading units, 144 texture mapping units, and 80 render output units, with 18 ray tracing cores. The pixel rate of 200.0 GPixel/s and texture rate of 360.0 GTexel/s provide theoretical throughput that aligns with the measured 1080p performance, where the card achieves 163 FPS at Low settings. The FP32 performance of 11.52 TFLOPS places this card in the mid-range segment, consistent with its 65th percentile ranking among all GPUs.

The Xe2-HPG architecture on TSMC's 5 nm process packs 19,600 million transistors into a 272 mm² die, achieving a transistor density of 72.1 million per square millimeter. This modern manufacturing process allows the card to maintain high clock speeds while staying within its 150 W power envelope. The PCIe 4.0 x8 interface provides sufficient bandwidth for the card's memory subsystem, though it may limit performance in some bandwidth-sensitive scenarios compared to x16 implementations.

Measured FPS Breakdown

At 1920x1080, the system delivers its strongest results across all settings presets. Low settings produce an average of 163 FPS, which represents 100% of the maximum achievable performance in this dataset. Medium settings reduce the average to 133 FPS with minimum and maximum values of 113 and 153 FPS respectively, representing an 18% performance cost over Low settings. High settings further reduce the average to 109 FPS, a 33% cost over Low, while Ultra settings drop to 68 FPS, a 58% cost over Low. This scaling suggests that each settings tier imposes a significant but predictable performance penalty at 1080p.

The 2560x1440 results show a similar pattern with reduced absolute numbers. Low settings yield 116 FPS average, which is 71% of the 1080p Low result. Medium settings produce 95 FPS with a range of 81 to 110 FPS, representing 71% of the 1080p Medium average. High settings achieve 78 FPS, 72% of the 1080p High result, while Ultra settings drop to 49 FPS, 72% of the 1080p Ultra average. The consistent 71-72% scaling factor across all settings at 1440p relative to 1080p indicates that the GPU scales linearly with pixel count when the resolution increases by 78%.

At 3840x2160, the performance scaling becomes less favorable. Low settings produce 72 FPS, which is 62% of the 1440p Low result and 44% of the 1080p Low result. Medium settings average 59 FPS with a range of 50 to 68 FPS, representing 62% of the 1440p Medium average. High settings achieve 49 FPS, 63% of the 1440p High result, while Ultra settings produce 30 FPS, 61% of the 1440p Ultra average. The slightly lower scaling factor at 4K compared to 1440p suggests that the GPU's memory bandwidth and shading resources become increasingly strained as pixel count approaches 8.3 million.
