Thief

Measured FPS Breakdown

The recorded data for Thief with the AMD Ryzen 7 5800XT and Intel Arc B370 spans three resolutions and four quality presets. The results show a wide performance spread, with the combo being playable only at the most modest settings.

At 3840x2160, the benchmark results are consistently below playable thresholds. The Low preset delivers an average of 31 FPS, while Medium drops to 24 FPS with recorded minimums of 20 FPS and maximums of 27 FPS. High settings average 18 FPS, and Ultra falls to 17 FPS. None of these averages approach the 60 FPS threshold, and the lack of recorded min/max values for most 4K entries suggests the frame pacing was too unstable to capture meaningful bounds.

Stepping down to 2560x1440 improves matters but not enough to cross the playable line. Low settings average 53 FPS, which is close to 60 but still short. Medium averages 41 FPS with a range of 35 to 47 FPS, High averages 31 FPS, and Ultra averages 29 FPS. The progression is linear and predictable, with each quality tier costing roughly 8 to 12 FPS on average.

At 1920x1080, the combo finally finds its footing. Low settings average 78 FPS, which clears the 60 FPS threshold with headroom. Medium averages 59 FPS, just one frame shy of the playable mark, with minimums of 50 and maximums of 68. High averages 45 FPS, and Ultra averages 43 FPS. The 1080p results show the largest gap between Low and Medium, a 19 FPS drop, whereas the gap between High and Ultra is only 2 FPS.

The overall pattern indicates that the Intel Arc B370 is the limiting factor at higher resolutions, while the CPU has enough headroom to push 1080p Low well past 60 FPS.

How This Combo Ranks

The database places this CPU and GPU pairing at rank 3433 out of 3720 tested combos for Thief. That puts it in the bottom 8 percent of all configurations measured, a position that reflects the GPU's low standing in the overall hardware hierarchy.

The Intel Arc B370 sits at the 5th percentile among all GPUs in the database, with an average benchmark score of 1184. Its nearest rivals in the GPU rankings are the ATI Mobility Radeon HD 5570 with a score of 1186 and a delta of negative 0.2 percent, the ATI Radeon HD 5770 at 1190 with a delta of negative 0.5 percent, the AMD Radeon HD 7650M at 1192 with a delta of negative 0.7 percent, and the AMD FirePro M2000 at 1168 with a delta of positive 1.4 percent. These are all older or lower-tier parts, which contextualizes why the combo lands so deep in the rankings.

The CPU, by contrast, is far more capable. The AMD Ryzen 7 5800XT sits at the 81st percentile among all CPUs, with an average benchmark score of 29879. Its nearest rivals include the AMD Ryzen 7 7840H at 29868 with a delta of 0 percent, the AMD Ryzen 7 8845HS at 29955 with a delta of negative 0.3 percent, the AMD Ryzen 7 7840HS at 29955 with a delta of negative 0.3 percent, and the AMD Ryzen 5 9600X at 29713 with a delta of 0.6 percent. The CPU is competitive with modern mid-range mobile and desktop parts, but the GPU drags the overall combo down.

The rank of 3433 out of 3720 is a direct consequence of this imbalance. A powerful eight-core processor paired with a GPU that benchmarks near decade-old mobile parts produces a system that cannot handle Thief at higher settings, regardless of resolution.

CPU and GPU Roles

The data makes it clear that the Intel Arc B370 is the dominant constraint in this pairing. The evidence lies in the scaling between resolutions and presets.

At 3840x2160, the gap between Low and Ultra is 14 FPS (31 to 17). At 2560x1440, the same gap is 24 FPS (53 to 29). At 1920x1080, the gap expands to 35 FPS (78 to 43). As resolution decreases, the preset scaling becomes more pronounced, which is the classic signature of a GPU-bound system. Higher resolutions saturate the GPU so thoroughly that even dropping from Ultra to Low yields only marginal gains. Lower resolutions relieve the GPU pressure, allowing the CPU to push more frames and making the preset differences more visible.

The CPU's role becomes apparent when comparing the 1080p Low result of 78 FPS to the 1440p Low result of 53 FPS. The 25 FPS drop from reducing resolution by 720p of vertical space shows that the GPU is still the bottleneck even at 1080p Low, since a CPU-bound scenario would show much smaller deltas. The Ryzen 7 5800XT, with its 8 cores, 16 threads, and boost clock of 4.80 GHz, is not the limiting factor here.

The Medium preset data reinforces this. At 1080p Medium, the average drops to 59 FPS with minimums of 50 and maximums of 68. At 1440p Medium, it falls to 41 FPS with a range of 35 to 47. At 4K Medium, it collapses to 24 FPS with a range of 20 to 27. The consistent frame ranges at each step suggest the GPU is working at full capacity while the CPU waits.

In short, the Ryzen 7 5800XT has ample compute headroom for Thief, but the Arc B370 cannot translate that headroom into playable frame rates beyond 1080p Low.

Similar Performance Alternatives

For the GPU, the nearest rivals in the database are the ATI Mobility Radeon HD 5570, the ATI Radeon HD 5770, the AMD Radeon HD 7650M, and the AMD FirePro M2000. The Arc B370's average score of 1184 is within 1.4 percent of all four parts. This means that a system using any of these GPUs would produce nearly identical frame rates in Thief. The ATI Radeon HD 5770, a desktop card from an older generation, would behave essentially the same as the Arc B370, as would the mobile-oriented HD 7650M and FirePro M2000.

It is notably these are not modern equivalents. They are older parts that happen to land within the same performance band in the database's measurements. The Arc B370 is a 3 nm part with 1280 shading units and a boost clock of 2400 MHz, but its integrated nature and system-shared memory clearly limit its real-world gaming throughput.

For the CPU, the nearest rivals are the AMD Ryzen 7 7840H, the AMD Ryzen 7 8845HS, the AMD Ryzen 7 7840HS, and the AMD Ryzen 5 9600X. The Ryzen 7 5800XT's average score of 29879 is within 0.6 percent of all four. Any of these CPUs paired with a GPU like the Arc B370 would yield the same Thief performance, because the GPU is the bottleneck. Conversely, pairing the Ryzen 7 5800XT with a much stronger GPU would likely produce dramatically better results in Thief, since the CPU is nowhere near its limits at 1080p Low.

The takeaway is that users looking to improve Thief performance should focus on the GPU side of the equation. Swapping the Arc B370 for a stronger part would have a far larger impact than any CPU change.

Best Settings per Resolution

At 3840x2160, no preset achieves 60 FPS. The best recorded average is 31 FPS at Low settings, which is far below the playable threshold. The verdict data confirms this, listing no playable settings for 4K.

At 2560x1440, the situation is nearly identical. The best average is 53 FPS at Low settings, still short of 60. The verdict data lists no playable settings for 1440p either.

At 1920x1080, Low settings are the only preset that clears the threshold, with an average of 78 FPS. Medium comes close at 59 FPS but misses the mark by a single frame. The verdict data lists Low as the sole playable setting and identifies it as the best settings choice, with an average FPS of 78 at that configuration.

For users who own this hardware, 1080p Low is the only viable configuration for Thief. Pushing to Medium at 1080p will cost one frame on average, and the recorded minimum of 50 FPS suggests occasional dips that could be noticeable during gameplay. The 78 FPS average at Low provides enough margin to keep the experience smooth.

The Verdict

The AMD Ryzen 7 5800XT and Intel Arc B370 can run Thief, but only in a narrow range of conditions. The verdict data is unambiguous: at 3840x2160, no settings are playable. At 2560x1440, no settings are playable. At 1920x1080, only Low settings clear the 60 FPS threshold, with an average of 78 FPS.

The experience at 1080p Low should be smooth, given the 18 FPS of headroom above the playable mark. However, users who want higher visual quality will be disappointed. Medium at 1080p averages 59 FPS, which is technically below the threshold, and the 50 FPS minimum suggests the system will dip into the 40s during demanding scenes. High and Ultra at 1080p are out of reach, and every preset at 1440p and 4K falls far short.

This is a system with a clear bottleneck. The Ryzen 7 5800XT is a strong processor, ranking in the 81st percentile, but the Arc B370 is a weak GPU, ranking in the 5th percentile. The combination produces a machine that is CPU-rich and GPU-poor, and Thief's performance reflects that imbalance. For this game, the answer is yes, it can run, but only at the lowest settings and at 1080p. Anything beyond that requires a different GPU.
