Thief

The AMD Ryzen 7 5800XT and Intel Arc B570 pairing delivers a wide spread of performance in Thief, ranging from a barely interactive 29 FPS at 4K Ultra to a smooth 133 FPS at 1080p Low. The data reveals a system that is decisively resolution-bound: it clears the 60 FPS playability threshold at 1080p across every preset and at 1440p up to Medium, but it falters completely at 3840x2160, where no setting reaches a playable average. This benchmark set, drawn from measured FPS data, shows a classic mid-range combo that excels at mainstream resolutions but runs out of headroom when pixel count escalates.

Measured FPS Breakdown

At 1920x1080, the combo is consistently fluid. The Low preset produces an average of 133 FPS, which is the highest figure recorded for this pairing in any configuration. Moving to Medium, the average drops to 101 FPS, with a minimum of 86 FPS and a maximum of 116 FPS, indicating stable frame pacing even during demanding scenes. The High preset yields 77 FPS on average, while the Ultra preset, the most demanding at this resolution, still maintains a respectable 73 FPS. All four 1080p presets comfortably exceed the 60 FPS playable threshold, with the gap between Low and Ultra representing a 60 FPS swing — from 133 down to 73 — which suggests the GPU is the primary scaling factor here, not the CPU.

At 2560x1440, performance drops noticeably but remains playable for two of the four presets. The Low preset averages 91 FPS, which is still well above the 60 FPS line. Medium follows at 69 FPS average, with a minimum of 59 FPS and a maximum of 79 FPS; the minimum barely misses the 60 FPS threshold, indicating occasional dips below the playable line even though the average clears it. High drops to 53 FPS average, and Ultra falls to 50 FPS. The transition from 1080p to 1440p costs roughly 42 FPS on Low (133 to 91) and 24 FPS on Ultra (73 to 50), showing that the penalty is proportionally larger at lower presets where the GPU is already working closer to its limits.

At 3840x2160, the picture is bleak. The Low preset averages 54 FPS, just under the 60 FPS target. Medium averages 41 FPS, with a minimum of 35 FPS and a maximum of 47 FPS, revealing significant frame variance. High averages 31 FPS, and Ultra averages 29 FPS. No 4K preset reaches the playable threshold; the best case is Low at 54 FPS, which is still 6 FPS short. The scaling from 1440p to 4K is severe: Low drops from 91 to 54 FPS (a 37 FPS loss), and Medium drops from 69 to 41 FPS (a 28 FPS loss). The data indicates that this combo is not viable for 4K gaming in Thief, regardless of settings.

CPU and GPU Roles

The benchmark results show that the Intel Arc B570 is the dominant constraint across all resolutions, but the CPU’s role becomes more apparent at lower settings. At 1080p Low, the 133 FPS average suggests the GPU is still managing to feed frames quickly, but the CPU’s capability is not the bottleneck — the Arc B570’s 11.52 TFLOPS FP32 throughput and 380.0 GB/s memory bandwidth are sufficient for this load. However, as resolution increases to 1440p and 4K, the GPU’s pixel rate of 200.0 GPixel/s and texture rate of 360.0 GTexel/s become limiting factors. The scaling from 1080p Ultra (73 FPS) to 1440p Ultra (50 FPS) is a 31.5% drop, which aligns with the increased pixel count of 2.25x; the fact that FPS does not drop proportionally suggests some CPU overhead is being relieved at higher resolutions, but the GPU is still the primary limiter.

The Ryzen 7 5800XT, with 8 cores and 16 threads based on Zen 3 architecture, shows its strength in single-threaded and lightly-threaded scenarios. Its 3DMark single-thread score of 959 and Cinebench R23 single-core score of 3359 indicate strong per-core performance, which Thief likely leverages for game logic and AI. At 4K Low, the average of 54 FPS versus 1080p Low’s 133 FPS — a 79 FPS gap — indicates that the GPU is doing most of the work, and the CPU is not the bottleneck even at the lowest preset. Conversely, at 1080p Ultra, the 73 FPS average shows that even with maximum settings, the CPU can feed the GPU adequately; the bottleneck is clearly the Arc B570’s rasterization throughput. The data implies that upgrading the GPU would yield immediate gains at 1440p and 4K, while the CPU would remain relevant for another generation.

How This Combo Ranks

In the database of tested combinations, this pairing holds a combo rank of 2994 out of 3720 total combos. This places it in the 80th percentile of all tested systems, meaning roughly 80% of the other CPU-GPU pairings in the database perform better in Thief. The rank reflects the GPU’s mid-range positioning: the Intel Arc B570 sits at the 65th percentile among all GPUs, while the Ryzen 7 5800XT sits at the 81st percentile among all CPUs. The combination of a high-percentile CPU with a lower-percentile GPU skews the overall rank downward, as the GPU becomes the limiting factor in most scenarios. The data suggests that this combo is better suited for CPU-intensive tasks than for high-refresh-rate gaming at high resolutions.

The rank of 2994 out of 3720 is not a failure, but it indicates that many cheaper or older GPU pairings would deliver comparable or better FPS in Thief. For instance, the GPU’s nearest rivals include the NVIDIA GeForce RTX 3070 Mobile (deltaPct 0.1) and the Intel Arc A750 (deltaPct -0.1), both of which score nearly identically in synthetic benchmarks. If those GPUs were paired with the same CPU, the Thief results would likely be within a few FPS, given the GPU’s dominant role. The CPU’s nearest rivals, such as the AMD Ryzen 7 7840H (deltaPct 0) and the AMD Ryzen 5 9600X (deltaPct 0.6), would not change the gaming outcome meaningfully because the GPU is the bottleneck. This rank reflects a system that is well-balanced for productivity but underwhelming for high-end gaming.

Similar Performance Alternatives

For the CPU, the nearest rivals based on average benchmark scores are the AMD Ryzen 7 7840H (avgScore 29868, deltaPct 0), the AMD Ryzen 7 8845HS (avgScore 29955, deltaPct -0.3), and the AMD Ryzen 7 7840HS (avgScore 29955, deltaPct -0.3). Each of these CPUs scores within 0.3% of the Ryzen 7 5800XT’s average of 29879, meaning they would deliver nearly identical frame rates in Thief when paired with the same GPU. The AMD Ryzen 5 9600X (avgScore 29713, deltaPct 0.6) is also within 1% of the 5800XT, so swapping to any of these would not shift the measured FPS by more than 1-2 frames. The data indicates that the CPU choice is effectively irrelevant for this game at these settings, as the GPU dominates.

For the GPU, the nearest rivals are the NVIDIA GeForce RTX 3070 Mobile (avgScore 20534, deltaPct 0.1), the Intel Arc A750 (avgScore 20582, deltaPct -0.1), the NVIDIA Quadro M4000M (avgScore 20480, deltaPct 0.4), and the AMD Radeon R9 M390X (avgScore 20662, deltaPct -0.5). All of these GPUs have synthetic scores within 0.5% of the Arc B570’s average of 20556. In Thief, this would translate to nearly identical FPS at every resolution and preset. For example, the Arc A750, which is the closest match, would produce the same 31 FPS at 4K High and the same 73 FPS at 1080p Ultra. The RTX 3070 Mobile, despite being a mobile part, would behave similarly, meaning users could expect no meaningful difference in playability. The Quadro M4000M and Radeon R9 M390X are older or professional parts, but their scores suggest they would also land within the same FPS range. This indicates that the Arc B570 is well-positioned against its direct competitors, offering no unique advantage or disadvantage in this specific game.
