Thief

The AMD Ryzen 7 5800X3D paired with the Intel Arc B570 lands at rank 2296 out of 2851 tested combos in Thief, placing it in the lower-mid tier of the database. This is a combination where the GPU is the clear bottleneck at higher resolutions, but the CPU’s strong multi-threaded and single-threaded scores keep frame rates respectable at 1080p. The data shows a system that is capable of smooth gameplay at lower settings, but struggles to maintain playable frame rates at 4K on higher presets. Benchmark results indicate that the 8-core, 16-thread Ryzen 7 5800X3D, with its 96 MB of shared L3 cache, provides ample headroom for this 2014 stealth title, while the Intel Arc B570’s 10 GB of GDDR6 memory and 380.0 GB/s bandwidth become the limiting factor as resolution scales up.

How This Combo Ranks

The combo’s position at 2296 out of 2851 tested combinations means it outperforms roughly 19.5% of all tested pairings in Thief. This is a below-average standing, driven primarily by the GPU’s modest performance tier. The Intel Arc B570 sits at the 65th percentile among all GPUs, with an average benchmark score of 20556, while the Ryzen 7 5800X3D ranks at the 80th percentile among all CPUs with an average score of 27896. That discrepancy—80th versus 65th percentile—tells the story: the CPU is the stronger component, but in Thief, the GPU’s limits cap the overall experience.

Looking at the CPU’s nearest rivals, the Ryzen 7 5800X3D’s average score of 27896 is essentially tied with the AMD Ryzen 7 6800U (27887, 0% delta), the Intel Core i9-10900K (27872, 0.1% ahead), and the AMD Ryzen AI 5 PRO 340 (27932, 0.1% behind). The Intel Core i5-12600KF trails slightly at 27799, a 0.3% gap. These are all within a rounding error, meaning the 5800X3D’s performance is comparable to a wide range of modern and previous-generation CPUs, but none of them can rescue this combo from the GPU’s constraints.

For the GPU, the nearest rivals include the NVIDIA GeForce RTX 3070 Mobile (20534, 0.1% behind the B570), the Intel Arc A750 (20582, 0.1% ahead), the NVIDIA Quadro M4000M (20480, 0.4% behind), and the AMD Radeon R9 M390X (20662, 0.5% ahead). The Arc B570’s average score of 20556 places it in a tight cluster with these parts, all within half a percent of each other. This reinforces that the B570 is a mid-range GPU, and in a game like Thief, its performance is what defines the combo’s ranking.

In practical terms, this ranking means the combo will deliver playable frame rates at 1080p and 1440p with adjusted settings, but it will not excel at 4K. The data shows that at 4K Ultra, the average FPS drops to 29, which is below the playable threshold for most users. The combo’s rank reflects this reality: it is not a high-end pairing, but it is far from the worst, offering a workable experience for gamers willing to dial back settings.

GPU Role

The Intel Arc B570 is built on TSMC’s 5 nm process with the Xe2-HPG architecture, codenamed Battlemage. It features 2304 shading units, 144 texture mapping units, and 80 raster output units. The GPU runs at a base clock of 2500 MHz, which is also its boost clock—there is no dynamic range, so performance is consistent under load. The memory subsystem consists of 10 GB of GDDR6 on a 160-bit bus, delivering a bandwidth of 380.0 GB/s. The memory clock is 2375 MHz, which translates to 19 Gbps effective.

In Thief, the GPU’s role is critical because the game’s lighting and shadow effects are demanding. The B570’s 80 ROPS and 200.0 GPixel/s pixel rate handle the rasterization, but the 10 GB VRAM becomes a constraint at higher resolutions. At 4K, the game’s textures and geometry require more memory bandwidth than the 380.0 GB/s can comfortably provide, which is why the average FPS at 4K High is 31, dropping to 29 at Ultra. The 160-bit bus width is narrow compared to higher-end cards, and this limits memory throughput.

The GPU’s FP32 performance of 11.52 TFLOPS and texture rate of 360.0 GTexel/s are adequate for a game from 2014, but they are not exceptional. The B570’s 18 ray tracing cores are present, but Thief does not use ray tracing, so they have no impact on these results. The GPU’s DirectX 12 Ultimate support (12_2) means it can handle modern APIs, but Thief was released in 2014, so it relies on older rendering paths that do not fully utilize the B570’s newer features.

The measured FPS data shows that the GPU is the limiting factor at 1440p and 4K. At 1080p Low, the combo hits 133 FPS, which suggests the CPU is feeding the GPU well, but as resolution increases, the GPU struggles. At 4K Low, the average FPS is 54, which is playable but far from smooth. The GPU’s 10 GB VRAM is sufficient for 1080p and 1440p, but at 4K, the memory bandwidth of 380.0 GB/s is not enough to maintain high frame rates on higher presets.

The GPU’s percentile rank of 65 places it in the upper half of all GPUs, but its nearest rivals are all within 0.5% in average score. This means the B570 is not a standout performer; it is a solid mid-range option that delivers expected results for its class. In Thief, the GPU’s 2500 MHz clock speed and 380.0 GB/s bandwidth are the key specs that determine frame rates, and the data shows they are sufficient for 1080p Medium and High, but not for 4K Ultra.

Resolution Scaling

The measured FPS data reveals a clear pattern of performance degradation as resolution increases from 1080p to 4K. At 1080p Low, the combo achieves 133 FPS. Moving to 1440p Low, the average FPS drops to 91, a 31.6% decrease. At 4K Low, the average FPS is 54, which is 59.4% lower than the 1080p Low result. This scaling indicates that the GPU is heavily stressed at higher resolutions, even on the lowest settings.

For Medium settings, the pattern is similar. At 1080p Medium, the average FPS is 101. At 1440p Medium, it drops to 69, a 31.7% decrease. At 4K Medium, the average FPS is 41, which is 59.4% lower than the 1080p Medium result. The consistency of these percentage drops—31.6% and 31.7% from 1080p to 1440p, and 59.4% from 1080p to 4K—suggests that the GPU’s performance scales predictably with resolution, confirming that the GPU is the bottleneck.

High settings show a similar trend. At 1080p High, the average FPS is 77. At 1440p High, it is 53, a 31.2% decrease. At 4K High, the average FPS is 31, a 59.7% decrease from 1080p High. Ultra settings follow the same pattern: 73 FPS at 1080p, 50 FPS at 1440p (31.5% decrease), and 29 FPS at 4K (60.3% decrease). The near-identical percentage drops across all settings strongly indicate that the limiting component is the GPU, as the CPU’s performance is not affected by resolution changes.

This resolution scaling analysis shows that the combo loses roughly 30% of its frame rate when moving from 1080p to 1440p, and another 40% when moving from 1440p to 4K. The data suggests that the Intel Arc B570’s 380.0 GB/s memory bandwidth and 160-bit bus are the primary constraints. At 1080p, the GPU can keep up with the CPU’s output, but at 1440p and 4K, the memory subsystem cannot feed the GPU fast enough, causing frame rates to plummet.

The FPS drops also indicate that the CPU is not a limiting factor in this game. The Ryzen 7 5800X3D’s 3.40 GHz base clock and 4.50 GHz boost clock, combined with its 8 cores and 16 threads, provide more than enough processing power for Thief. Even at 4K Low, where the GPU is most stressed, the average FPS of 54 is higher than at 4K Ultra (29), showing that the CPU can drive the GPU at lower settings. The CPU’s 96 MB of L3 cache is particularly beneficial for gaming, as it reduces memory latency and improves frame pacing, but this advantage is overshadowed by the GPU’s limitations at higher resolutions.

Settings Recommendations

Based on the measured FPS data, the best experience for this combo in Thief is achieved at 1080p with Medium settings. At 1080p Medium, the average FPS is 101, with a minimum of 86 and a maximum of 116. This provides a smooth, playable experience with good visual quality. The minimum FPS of 86 ensures that there are no significant stutters, even during intense scenes.

At 1080p High, the average FPS drops to 77, which is still playable but leaves less headroom for demanding scenes. At 1080p Ultra, the average FPS is 73, which is only slightly lower than High, but the minimum FPS is not recorded, meaning there could be occasional dips. For a game like Thief, where stealth and precision matter, a stable frame rate is more important than maximum visual fidelity, so Medium settings at 1080p are the recommended choice.

For 1440p, the data shows that Medium settings are the highest playable option. At 1440p Medium, the average FPS is 69, with a minimum of 59 and a maximum of 79. The minimum FPS of 59 is just at the edge of playability, but it is acceptable for a single-player stealth game. At 1440p High, the average FPS drops to 53, which is below the 60 FPS threshold that most gamers prefer. At 1440p Ultra, the average FPS is 50, which is also below 60. Therefore, Medium settings at 1440p are the best balance of visual quality and performance.

At 4K, the data shows that only Low settings are playable. At 4K Low, the average FPS is 54, which is below 60 but still manageable for a slower-paced stealth game. At 4K Medium, the average FPS drops to 41, and at 4K High and Ultra, it falls to 31 and 29, respectively. These lower frame rates are not recommended for a smooth experience. The data indicates that 4K is not a viable resolution for this combo, and users should stick to 1080p or 1440p for the best experience.

The recommendation is to prioritize frame rate stability over visual quality. At 1080p Medium, the min FPS of 86 ensures a consistent experience, while at 1440p Medium, the min FPS of 59 is acceptable but closer to the edge. The measured data shows that the GPU’s 10 GB VRAM and 380.0 GB/s bandwidth are sufficient for Medium settings at 1080p and 1440p, but not for higher presets at these resolutions. Users who want a smoother experience can lower to 1080p Low, which delivers 133 FPS, but Medium offers a better visual balance.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best performance. With Low settings, the average FPS is 133, which is extremely smooth and well above the 60 FPS threshold. Medium settings reduce the average to 101 FPS, with a minimum of 86 and a maximum of 116, providing a highly playable experience. High settings lower the average to 77 FPS, which is still smooth, and Ultra settings yield 73 FPS. The data shows that at 1080p, all settings are playable, with Low and Medium offering the highest frame rates.

At 2560x1440, the performance drops noticeably. Low settings achieve an average of 91 FPS, which is smooth. Medium settings reduce the average to 69 FPS, with a minimum of 59 and a maximum of 79. This is playable, but the minimum FPS is close to the 60 FPS threshold. High settings lower the average to 53 FPS, which is below 60 and may cause noticeable stutters in demanding scenes. Ultra settings yield 50 FPS, which is also below 60. At 1440p, only Low and Medium settings provide a consistently smooth experience.

At 3840x2160, the combo struggles. Low settings achieve an average of 54 FPS, which is playable but not ideal. Medium settings drop to 41 FPS, with a minimum of 35 and a maximum of 47, which is below the playable threshold for most users. High settings yield 31 FPS, and Ultra settings drop to 29 FPS. These frame rates are not suitable for a smooth gaming experience, and the data shows that 4K is not a realistic option for this combo.

The measured FPS breakdown across all resolutions and settings shows a clear hierarchy. At 1080p, the combo can handle any preset, with Low and Medium providing the best frame rates. At 1440p, Medium is the highest playable preset, with Low offering even higher frame rates. At 4K, only Low is playable, and even then, the average FPS of 54 is below 60. The data indicates that the GPU is the primary bottleneck, and users should prioritize lower resolutions and settings to achieve smooth gameplay.

The minimum FPS values are only recorded for Medium settings at each resolution: 86 at 1080p, 59 at 1440p, and 35 at 4K. These minimums show that the frame rate is stable at 1080p, but at 1440p and 4K, there are dips that could affect gameplay. The maximum FPS values for Medium settings are 116 at 1080p, 79 at 1440p, and 47 at 4K, further confirming the GPU’s limitations at higher resolutions.

CPU Role

The AMD Ryzen 7 5800X3D is an 8-core, 16-thread processor based on the Zen 3 architecture, codenamed Vermeer. It has a base clock of 3.40 GHz and a boost clock of 4.50 GHz, with a TDP of 105 W. The CPU supports DDR4 memory in a dual-channel configuration, with a memory bandwidth of 51.2 GB/s. Its most notable feature is the 96 MB of shared L3 cache, which is significantly larger than typical CPUs and helps reduce memory latency in gaming workloads.

In Thief, the CPU’s role is to feed the GPU with draw calls and handle game logic. The benchmark results show that the Ryzen 7 5800X3D is more than capable of this task. In Cinebench R23, the CPU scores 14317 in multi-core and 1452 in single-core. In Geekbench, it scores 11765 in multi-core and 2017 in single-core. These scores indicate strong performance that is not a bottleneck in this game.

The CPU’s 96 MB of L3 cache is particularly beneficial for Thief, which has complex level geometry and AI routines. The large cache allows more data to be stored closer to the cores, reducing the need to access slower system memory. This is reflected in the frame rates at 1080p, where the combo achieves 133 FPS at Low settings, indicating that the CPU is not limiting performance.

The nearest rivals for the CPU, based on average benchmark scores, are the AMD Ryzen 7 6800U (27887, 0% delta), Intel Core i9-10900K (27872, 0.1% ahead), AMD Ryzen AI 5 PRO 340 (27932, 0.1% behind), and Intel Core i5-12600KF (27799, 0.3% behind). These scores are all within 0.3% of each other, meaning the 5800X3D is performance-equivalent to a wide range of CPUs. However, the 5800X3D’s 3D V-Cache, which is not present in these rivals, gives it an advantage in gaming scenarios where cache size matters.

In Thief, the CPU’s 3.40 GHz base clock and 4.50 GHz boost clock are adequate for the game’s requirements. The 8 cores and 16 threads handle the game’s multithreaded workload efficiently, as evidenced by the 3DMark 16-thread score of 7299 and max-thread score of 7285. The single-thread score of 884 in 3DMark and 3234 in PassMark indicate good single-core performance, which is important for games that rely heavily on one or two threads.

The CPU’s memory bandwidth of 51.2 GB/s is sufficient for Thief, as the game does not require excessive memory throughput. The CPU’s support for ECC memory is a feature that is not utilized in gaming but adds to its versatility. The CPU’s PCIe Gen 4 support with 20 lanes provides ample bandwidth for the GPU, although the Arc B570 uses a PCIe 4.0 x8 interface, which is half the bandwidth of x16. This is not a bottleneck in Thief, as the game’s data transfer requirements are modest.

Overall, the CPU is the stronger component in this combo, and its performance is not a limiting factor in Thief. The data shows that the Ryzen 7 5800X3D provides more than enough processing power, and the frame rates are constrained by the GPU’s capabilities, especially at higher resolutions. The CPU’s large L3 cache and high clock speeds ensure that it can keep up with the GPU at 1080p and 1440p, but the GPU’s 10 GB VRAM and 380.0 GB/s bandwidth are insufficient for 4K gaming.
