Thief

The AMD Ryzen 5 5600X and Intel Arc B370 combination delivers a highly constrained gaming experience in Thief, with the benchmark data revealing a system that is overwhelmingly limited by its graphics solution. While the CPU holds up its end of the bargain, the integrated Arc B370 struggles to maintain playable frame rates at higher resolutions, making this pairing a study in severe bottlenecking and the importance of matching components to the target display output.

Resolution Scaling

The measured FPS data in Thief demonstrates a stark and predictable collapse in performance as resolution increases, a classic sign of a GPU-bound workload. At 1080p with Low settings, the combo achieves an average of 78 FPS, which drops to 53 FPS at 1440p and further to 31 FPS at 4K. This represents a 32% decrease from 1080p to 1440p and a 60% decrease from 1080p to 4K, showing that the rendering pipeline becomes progressively more strained as pixel count grows.

The scaling pattern becomes even more telling when examining the High settings tier. The average FPS at 1080p is 45, falling to 31 at 1440p (a 31% drop) and then to 18 at 4K (a 60% drop from 1080p). The consistency of these percentage drops across different settings presets strongly indicates that the limiting component is the GPU, as the CPU's workload does not scale significantly with resolution in this 2014 stealth title. If the CPU were the bottleneck, we would expect to see similar FPS numbers regardless of resolution, but the data shows a linear decline that tracks directly with the increase in rendered pixels.

The difference between Low and Ultra settings at the same resolution further confirms this analysis. At 1080p, Low yields 78 FPS while Ultra yields 43 FPS, a 45% reduction. At 4K, Low yields 31 FPS while Ultra yields 17 FPS, a 45% reduction as well. The proportional impact of settings is nearly identical across resolutions, which is characteristic of a GPU that is fully saturated at every quality level. The Arc B370, with its integrated graphics architecture, is simply overwhelmed by the demands of 4K rendering, and even the transition to 1440p cuts performance roughly in half compared to 1080p for most settings.

CPU Role

The AMD Ryzen 5 5600X is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Vermeer, built on a 7 nm process at TSMC. Its base clock of 3.70 GHz and boost clock of 4.60 GHz provide solid single-threaded performance, as evidenced by a 3dmark single-thread score of 917 and a passmark single-thread score of 3364. The CPU also shows strong multi-threaded capability with a cinebench r23 multicore score of 11838 and a passmark multithread score of 21858.

In the context of Thief, a game released in 2014, the 5600X's six cores and twelve threads are more than sufficient to handle the game's CPU demands. The 32 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth ensure that data can be fed to the GPU without introducing a CPU-side bottleneck. The CPU's percentile ranking of 75 against all CPUs indicates it sits in the upper quartile of processors, and its nearest rivals include the AMD Ryzen 7 4800H (deltaPct 0.1), AMD Ryzen 5 PRO 6650U (deltaPct -0.5), and Intel Core i7-11700 (deltaPct -0.5), all of which have nearly identical average benchmark scores.

The benchmark results suggest that the 5600X is not the limiting factor in this combo. At 1080p Low, the system produces 78 FPS, which is a reasonable number for a game of Thief's era, but at higher resolutions the FPS drops dramatically. If the CPU were the bottleneck, we would expect to see the FPS plateau at a certain level regardless of resolution or settings, but instead the data shows a continuous decline that tracks with GPU load. The CPU's cinebench r15 single-core score of 254 and geekbench single-core score of 1989 indicate it can handle the game logic and AI calculations required by Thief without issue, leaving the GPU as the clear performance limiter.

GPU Role

The Intel Arc B370 is an integrated graphics processor based on the Xe3-LPG architecture, built on Intel's 3 nm process. It features 1280 shading units, 40 texture mapping units, and 20 raster output units, along with 10 ray tracing cores. Its boost clock reaches 2400 MHz, and it has a pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s. The GPU's FP32 performance is rated at 6.144 TFLOPS, and its TDP is just 25 W, indicating it is designed for power efficiency rather than raw performance.

The GPU's 3dmark Steel Nomad DX12 score is 1184, which places it in the 5th percentile of all GPUs. Its nearest rivals include the ATI Mobility Radeon HD 5570 (deltaPct -0.2), ATI Radeon HD 5770 (deltaPct -0.5), and AMD Radeon HD 7650M (deltaPct -0.7), all of which are significantly older and less capable parts. This low percentile ranking is reflected directly in the measured FPS data, where the combo struggles to maintain playable frame rates at higher resolutions.

The GPU uses System Shared memory, which means its performance is dependent on the system's main memory bandwidth and capacity. This shared memory architecture is a significant drawback, as the GPU must compete with the CPU for memory access, and the "System Dependent" bandwidth figure suggests that performance can vary based on the rest of the system. In Thief, this manifests as a hard ceiling on performance: at 4K Ultra, the average FPS is just 17, and even at 1080p High, it only reaches 45 FPS. The GPU's low ROP count of 20 and modest pixel rate of 48.00 GPixel/s are likely the primary constraints, as the game's rendering at higher resolutions requires more pixel fill rate than this GPU can provide.

How This Combo Ranks

The combo ranks 2634 out of 2851 tested combinations in Thief, placing it in the bottom 7.6% of all systems. This is an exceptionally low ranking that underscores the GPU's severe performance limitations. The CPU's high percentile ranking (75th) does little to compensate for the GPU's 5th percentile ranking, and the overall system performance is dragged down by the integrated graphics solution.

This ranking suggests that the vast majority of other tested combos, even those with older or less capable CPUs, are able to outperform this pairing in Thief. The data indicates that the Intel Arc B370 is the clear weak link, as its 3dmark score of 1184 is in the bottom 5% of all GPUs, and its nearest rivals are all legacy ATI parts from over a decade ago. The Ryzen 5 5600X, by contrast, is a top-quartile CPU that should be capable of driving much higher frame rates if paired with a more powerful discrete GPU.

The 7.6% ranking also implies that this combo is unsuitable for playing Thief at anything beyond low resolutions and settings. The measured FPS data shows that the only configuration that achieves a smooth 60+ FPS is 1080p Low at 78 FPS, and even 1080p Medium dips to 59 FPS, which is borderline. At 1440p or 4K, the system falls well below 60 FPS in all settings, making the experience stuttery and unplayable for most users. This is a textbook example of a CPU that is far ahead of its GPU counterpart, creating a massive imbalance that limits the system's overall gaming potential.

Measured FPS Breakdown

The measured FPS data provides a comprehensive look at the system's performance across 12 different configurations. At 1920x1080, the combo achieves 78 FPS on Low settings, 59 FPS on Medium (with a minimum of 50 and maximum of 68), 45 FPS on High, and 43 FPS on Ultra. This shows a clear progression where each step up in settings costs between 14 and 19 FPS, with the largest drop coming from Low to Medium at 19 FPS.

At 2560x1440, the performance drops significantly. Low settings yield 53 FPS, Medium averages 41 FPS (with a minimum of 35 and maximum of 47), High averages 31 FPS, and Ultra averages 29 FPS. The difference between Low and Ultra at 1440p is 24 FPS, which is a larger absolute gap than at 1080p, indicating that the GPU is becoming more sensitive to settings changes as resolution increases.

At 3840x2160, the system is clearly overmatched. Low settings produce 31 FPS, Medium averages 24 FPS (with a minimum of 20 and maximum of 27), High averages 18 FPS, and Ultra averages 17 FPS. None of these configurations achieve the 30 FPS threshold that is often considered the minimum for playability, and only Low settings barely exceed it at 31 FPS. The minimum FPS readings at 4K Medium (20 FPS) suggest that the system can experience significant frame drops, making the experience even more inconsistent.

The data shows that the only truly playable configuration is 1080p Low at 78 FPS, with 1080p Medium at 59 FPS being a marginal option. All other configurations fall below 60 FPS, and anything above 1440p Low is in sub-30 FPS territory, which is generally considered unplayable for a stealth game that requires quick reactions.

FAQ

Q: What is the best resolution and settings combo for this system?

A: The data shows that 1920x1080 with Low settings achieves 78 FPS, which is the only configuration that exceeds 60 FPS. 1080p Medium yields 59 FPS, which is close to playable, but 1440p Low drops to 53 FPS, and 4K Low falls to 31 FPS.

Q: Is the CPU or GPU the limiting factor in Thief?

A: The GPU is clearly the limiting factor. The Ryzen 5 5600X has a 75th percentile CPU ranking, while the Intel Arc B370 has a 5th percentile GPU ranking. The FPS drops consistently as resolution increases, which is a hallmark of GPU-bound performance.

Q: How does this combo compare to other systems in Thief?

A: This combo ranks 2634 out of 2851 tested combinations, placing it in the bottom 7.6%. The GPU's nearest rivals are all legacy ATI parts from the HD 5000 and 7000 series, indicating the Arc B370 is a very low-performing graphics solution.

Q: Can this system handle 4K gaming in Thief?

A: No. The highest average FPS at 4K is 31 on Low settings, and Ultra settings drop to 17 FPS. Even the best 4K configuration is below the 60 FPS target and barely touches 30 FPS.

Q: What is the impact of settings changes on performance?

A: At 1080p, moving from Low to Ultra costs 35 FPS (from 78 to 43). At 1440p, the same change costs 24 FPS (from 53 to 29). At 4K, the cost is 14 FPS (from 31 to 17). The absolute FPS loss shrinks as resolution increases because the GPU is already severely constrained.

Q: How does the CPU's performance compare to its rivals?

A: The Ryzen 5 5600X has an average benchmark score of 21771, which is nearly identical to its nearest rivals: the AMD Ryzen 7 4800H (21749, deltaPct 0.1) and the AMD Ryzen 5 PRO 6650U (21874, deltaPct -0.5). Its performance is effectively on par with these processors.

Settings Recommendations

Based on the measured FPS data, the only configuration that provides a smooth, responsive experience in Thief is 1920x1080 with Low settings, which achieves an average of 78 FPS. This is the recommended preset for players who prioritize frame rate and responsiveness, as it is the sole configuration that comfortably exceeds the 60 FPS threshold. The Medium preset at 1080p yields 59 FPS, which is playable but may experience occasional dips, and it is a viable alternative for those who want slightly better visual quality without sacrificing too much performance.

For players who insist on higher resolutions, the data suggests that 1440p Low at 53 FPS is the best option, though it falls below 60 FPS and may feel less smooth. At 4K, the system is not capable of delivering a playable experience, as even Low settings only reach 31 FPS, and the minimum FPS at Medium is 20, which would result in noticeable stuttering. The High and Ultra presets are not recommended at any resolution above 1080p, as they push the system below 45 FPS at 1440p and below 20 FPS at 4K.

Given the GPU's 5th percentile ranking and its position among decade-old ATI parts, the Arc B370 is fundamentally unsuited for modern gaming at high resolutions. The most sensible approach is to play at 1080p Low or Medium, accepting the visual compromises in exchange for a playable frame rate. The Ryzen 5 5600X has ample headroom to drive higher frame rates, but the GPU simply cannot keep up, making this a system where the settings must be tuned to the GPU's limitations rather than the CPU's capabilities.
