Thief

The AMD Ryzen 5 9600X and Intel Arc B570 combination delivers a playable but resolution-sensitive experience in Thief. The data shows a clear progression from excellent 1080p performance to marginal 4K results, with the GPU emerging as the primary constraint at higher resolutions. The combo ranks in the lower half of tested configurations, indicating that while this pairing is competent, it does not lead the pack in this title.

Resolution Scaling

The measured FPS data reveals a steep performance gradient as resolution increases. At 1080p with High settings, the combo produces 77 FPS. Moving to 1440p drops this to 53 FPS, a 31% reduction. At 4K, the average falls to 31 FPS, a 60% drop from the 1080p High result. This scaling pattern strongly suggests the Intel Arc B570 becomes the limiting factor beyond 1080p.

The Low settings preset tells a similar story with a wider spread. At 1080p, the combo reaches 133 FPS, which is the highest recorded value in the entire dataset. Dropping to 1440p yields 91 FPS, a 32% decline. At 4K, the average is 54 FPS, a 59% reduction from 1080p. The consistent 59-60% drop from 1080p to 4K across both High and Low settings indicates a scalable GPU bottleneck rather than a CPU limitation.

Medium settings provide the only complete min/max data across all resolutions. At 1080p, the average is 101 FPS with a minimum of 86 FPS and maximum of 116 FPS. At 1440p, the average falls to 69 FPS, with a minimum of 59 FPS and maximum of 79 FPS. At 4K, the average is 41 FPS, with a minimum of 35 FPS and maximum of 47 FPS. The minimum frame rates at 1440p (59 FPS) and 4K (35 FPS) suggest that frame pacing remains stable even when the average dips, which is a positive sign for gameplay smoothness.

Ultra settings exhibit the most severe resolution penalty. At 1080p, the average is 73 FPS. At 1440p, this drops to 50 FPS, a 32% reduction. At 4K, the average is 29 FPS, a 60% decline from 1080p. This 29 FPS result at 4K Ultra is the lowest recorded average in the dataset, and it falls below the generally accepted threshold for smooth gameplay. The consistent 60% drop from 1080p to 4K across all four settings presets confirms that the scaling is resolution-driven rather than settings-driven.

How This Combo Ranks

The combo ranks 2296 out of 2851 tested combinations in Thief. This places it in the bottom 20% of all tested configurations, which is a notable finding given the individual component specifications. The rank indicates that while the CPU and GPU are both current-generation parts, their combined performance in this specific title does not compete with the top-tier pairings in the database.

This ranking is particularly interesting when considering the individual component percentiles. The CPU sits at the 81st percentile among all processors, while the GPU is at the 65th percentile among all graphics cards. The combo rank of 2296/2851 (19.5th percentile) is significantly lower than either component's individual standing. This discrepancy suggests that Thief presents specific challenges for this pairing, likely related to the GPU's architectural characteristics at higher resolutions.

The nearest rival data for the GPU provides context for its performance tier. The Intel Arc B570 has an average benchmark score of 20556, which is within 0.5% of the NVIDIA GeForce RTX 3070 Mobile (20534) and the AMD Radeon R9 M390X (20662). This places the B570 in a competitive mid-range segment, but the 4K results in Thief indicate that this performance level is insufficient for high-resolution gaming in this title.

GPU Role

The Intel Arc B570 features 10 GB of GDDR6 memory on a 160-bit bus, providing 380.0 GB/s of bandwidth. This memory configuration is adequate for 1080p and 1440p gaming, but the 4K results suggest that the 10 GB capacity and 160-bit bus width become limiting factors at higher resolutions. The GPU's base and boost clocks are both 2500 MHz, which is a relatively high clock speed for a mid-range card.

The GPU's compute capabilities include 2304 shading units, 144 texture mapping units, and 80 render output units. The texture rate of 360.0 GTexel/s and pixel rate of 200.0 GPixel/s are respectable for this class of GPU. However, the FP32 performance of 11.52 TFLOPS appears insufficient for Thief at 4K, where the combo cannot maintain 60 FPS even at Low settings.

The memory bandwidth of 380.0 GB/s is a critical factor in the resolution scaling observed. At 1080p, the bandwidth is sufficient to feed the GPU's shading units, resulting in 133 FPS at Low settings. At 4K, the pixel throughput requirement quadruples, and the 160-bit memory bus struggles to deliver the necessary data. This explains the consistent 60% performance drop from 1080p to 4K across all settings.

The GPU's DirectX 12 Ultimate support and Vulkan 1.4 compliance are relevant for modern titles, but Thief was released before these APIs were widely adopted. The game's engine likely relies on older rendering paths, which may not fully utilize the B570's architectural strengths. The PassMark DirectX 11 score of 118 and DirectX 10 score of 65 suggest that the GPU's legacy API performance is modest, which could explain the sub-optimal results in this 2014 title.

Measured FPS Breakdown

At 1080p, the combo delivers its strongest performance. The Low preset achieves 133 FPS, which is the highest average in the dataset. Medium settings produce 101 FPS with a minimum of 86 FPS and maximum of 116 FPS. High settings yield 77 FPS, while Ultra settings drop to 73 FPS. The spread from Low to Ultra is 60 FPS, representing a 45% performance range.

At 1440p, the performance envelope compresses. Low settings achieve 91 FPS, while Medium drops to 69 FPS with a minimum of 59 FPS and maximum of 79 FPS. High settings produce 53 FPS, and Ultra settings fall to 50 FPS. The spread from Low to Ultra is 41 FPS, a 45% range similar to 1080p. The 1440p Medium minimum of 59 FPS indicates that frame times remain stable even when the average dips below 60 FPS.

At 4K, the combo's limitations become apparent. Low settings achieve 54 FPS, which is the only preset above 50 FPS at this resolution. Medium settings produce 41 FPS with a minimum of 35 FPS and maximum of 47 FPS. High settings drop to 31 FPS, and Ultra settings fall to 29 FPS. The 4K Medium minimum of 35 FPS highlights the GPU's struggle at this resolution, as even the minimum frame rate falls below playable thresholds.

Across all resolutions, the relative performance ordering remains consistent: Low beats Medium, Medium beats High, and High beats Ultra. The performance gaps between presets are relatively uniform. At 1080p, the gap between Low and Medium is 32 FPS, between Medium and High is 24 FPS, and between High and Ultra is 4 FPS. At 1440p, these gaps are 22 FPS, 16 FPS, and 3 FPS respectively. At 4K, they are 13 FPS, 10 FPS, and 2 FPS. The shrinking absolute gaps at higher resolutions confirm that the GPU becomes the dominant bottleneck.

Settings Recommendations

The measured data provides clear guidance for optimal settings at each resolution. At 1080p, the High preset offers the best balance of visual quality and performance. The 77 FPS average is well above playable thresholds, and the 4 FPS difference between High and Ultra suggests that Ultra offers minimal visual benefit for the performance cost. Players seeking maximum frame rates can use Low settings to achieve 133 FPS, but the Medium preset's 101 FPS with an 86 FPS minimum provides a strong compromise.

At 1440p, the Medium preset is the recommended choice. The 69 FPS average with a 59 FPS minimum approaches the 60 FPS target, and the visual upgrade from Low is substantial. The High preset's 53 FPS average falls below 60 FPS, making it less ideal for smooth gameplay. Ultra settings at 50 FPS offer no meaningful advantage over High in this title's engine.

At 4K, the Low preset is the only viable option for acceptable performance. The 54 FPS average is above 30 FPS but below 60 FPS, indicating that 4K gaming is possible but not optimal with this combo. The Medium preset's 41 FPS average and 35 FPS minimum will result in noticeable stuttering during action sequences. The High and Ultra presets, at 31 FPS and 29 FPS respectively, are not recommended for playable frame rates.

For players prioritizing frame rate stability, the Medium preset offers the most consistent experience. This is the only preset with complete min/max data across all resolutions, and the minimum frame rates remain within 15% of the averages. The Low preset lacks min/max data, but the high averages suggest it would provide the smoothest experience at all resolutions.

CPU Role

The AMD Ryzen 5 9600X features 6 cores and 12 threads based on the Zen 5 architecture. The base clock of 3.90 GHz and boost clock of 5.40 GHz provide strong single-threaded performance, which is reflected in the Cinebench R23 single-core score of 2183.5. This CPU performance is more than sufficient for Thief, which was released in 2014 and does not demand high core counts.

The CPU's 32 MB of shared L3 cache and 1 MB L2 cache per core provide ample memory hierarchy for this title. The dual-channel DDR5 memory support with 89.6 GB/s bandwidth exceeds the requirements of a 2014 game. The CPU's 3DMark single-thread score of 1253 and 2-thread score of 2456 indicate strong single-thread performance, which is critical for older game engines that rely on a primary rendering thread.

The CPU's percentile ranking of 81st among all processors suggests it is a high-performing part, but the combo rank in Thief indicates that the GPU is the limiting factor. The measured FPS scaling from 1080p to 4K shows no evidence of CPU bottlenecking. At 1080p Low, the 133 FPS result suggests the CPU can feed the GPU effectively, as the GPU is not the constraint at this resolution.

The CPU's nearest rivals in the benchmark database include the AMD Ryzen 7 PRO 5755GE (0.2% higher average score) and AMD Ryzen 7 7840H (0.5% lower average score). While these comparisons are based on synthetic benchmarks, they indicate that the 9600X sits in a competitive performance tier. In Thief, however, the GPU's limitations prevent the CPU from demonstrating its full potential at higher resolutions.
