Thief

The AMD Ryzen 5 4600G paired with the Intel Arc B580 lands in the 2843rd position out of 3720 tested combinations for Thief, placing it in the lower-middle portion of the database. This rank reflects a pairing where the CPU, a 2020-era 7nm Zen 2 part, sits well below the GPU in terms of relative performance potential. The Arc B580, by contrast, is a modern 5nm Battlemage part that benchmarks near the top quartile of all GPUs. The data indicates this is not a balanced pairing; the Ryzen 5 4600G, with its 6 cores and 12 threads, is the limiting factor in most scenarios, holding back a GPU that is capable of significantly higher frame rates in this 2014 stealth title.

How This Combo Ranks

The 2843rd rank out of 3720 combos places this configuration in the 76th percentile of all tested pairings, meaning roughly a quarter of tested systems perform worse. This is a mediocre result for a game like Thief, which is not particularly demanding by modern standards. The ranking is dragged down primarily by the CPU, whose average benchmark score of 17507 places it in the 71st percentile of all CPUs. To contextualize, the Ryzen 5 4600G sits within 1% of the AMD Ryzen 3 PRO 5355GE, AMD Ryzen 3 8300GE, Intel Core 7 150U, and Intel Core i3-14100T in average CPU score. This is a tight cluster of mid-range processors, but none of them are known for high-end gaming throughput.

The GPU, however, is a different story. The Arc B580’s average benchmark score of 23021 places it in the 68th percentile of all GPUs, and its nearest rivals are the AMD Radeon RX 580 2048SP, NVIDIA GeForce RTX 2080, NVIDIA GeForce RTX 3080, and NVIDIA P106-100, all within 1% of its score. This suggests the GPU is capable of competing with much older flagship cards from NVIDIA, yet the overall combo rank suffers because the CPU cannot feed it adequately. In Thief specifically, the measured FPS data shows that at 1080p High settings, the combo achieves 87 FPS, but this is far below what the GPU alone could deliver if paired with a stronger processor. The rank is a reflection of this bottleneck, not of the GPU’s inherent capability.

GPU Role

The Intel Arc B580 is the clear performance driver in this combo. It features 12 GB of GDDR6 memory on a 192-bit bus, yielding a memory bandwidth of 456.0 GB/s. The base and boost clocks are both set at 2670 MHz, which is a high operating frequency for a GPU. The memory clock runs at 2375 MHz, translating to 19 Gbps effective. These specifications are significant for Thief, a game that, while from 2014, can still stress memory bandwidth at higher resolutions due to its detailed textures and lighting effects.

In the measured FPS data, the GPU’s influence is most apparent at 4K resolution. At 3840x2160 with Low settings, the combo produces 61 FPS, which is playable. Moving to Medium settings at 4K drops the average to 46 FPS, with a minimum of 39 and maximum of 53. At High settings, the average falls to 35 FPS, and at Ultra, it bottoms out at 33 FPS. These numbers show a clear scaling pattern where the GPU is working hard to fill the 4K frame buffer. The 12 GB VRAM is a substantial asset here; even at 4K Ultra, the game is unlikely to exceed this capacity, so the frame rate drops are due to raw compute and fill rate, not memory exhaustion.

The GPU’s compute capabilities, measured at 13.67 TFLOPS FP32, are more than sufficient for Thief. The pixel rate of 213.6 GPixel/s and texture rate of 427.2 GTexel/s are also high, ensuring that the GPU is not the primary bottleneck until 4K Ultra settings are applied. At lower resolutions, the GPU is often idle waiting for the CPU to deliver draw calls, which explains why the 1080p results are not proportionally higher than the 4K results. The GPU is also capable of leveraging modern APIs, with DirectX 12 Ultimate support, though Thief itself is an older title that likely uses DirectX 11, which the GPU handles via its passmark_directx_11 score of 128.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals a classic CPU bottleneck at lower resolutions that gradually shifts to a GPU bottleneck at higher resolutions. At 1920x1080 with High settings, the combo averages 87 FPS. Moving to 2560x1440 High, the average drops to 60 FPS, a 31% reduction. At 3840x2160 High, the average falls to 35 FPS, another 42% drop from 1440p. This scaling pattern is consistent with a CPU-limited scenario at 1080p, where the Ryzen 5 4600G cannot push frames faster, and a GPU-limited scenario at 4K, where the Arc B580 is maxed out.

The Low settings data further illustrates this. At 1080p Low, the combo hits 130 FPS, but at 1440p Low, it drops to 103 FPS, and at 4K Low, it falls to 61 FPS. The 1080p to 1440p drop is only 21%, which is modest, suggesting the CPU is still a constraint at 1080p Low. However, the 1440p to 4K drop is 41%, indicating the GPU is now the limiting factor. The Medium settings show a similar trend: 114 FPS at 1080p, 78 FPS at 1440p, and 46 FPS at 4K. The percentage drops from 1080p to 1440p are 32% for High, 21% for Low, and 32% for Medium, while the drops from 1440p to 4K are 42% for High, 41% for Low, and 41% for Medium.

The key insight is that the CPU bottleneck is most pronounced at 1080p, where the gap between Low (130 FPS) and Ultra (83 FPS) is 47 FPS, a 36% reduction. At 4K, the gap between Low (61 FPS) and Ultra (33 FPS) is 28 FPS, a 46% reduction. This shows that at 4K, the GPU’s workload dominates, and the CPU’s slower single-thread performance (3dmark_single_thread score of 726) becomes less relevant. For a 2014 game, the data suggests that 1440p is the sweet spot for this combo, where the CPU and GPU are more balanced, delivering 60 FPS at High settings.

FAQ

Q: Is the AMD Ryzen 5 4600G strong enough for the Intel Arc B580 in Thief?

A: No. The data shows that at 1080p High, the combo achieves 87 FPS, but this is likely CPU-limited, as the CPU’s single-thread score is only 726 in 3dmark. The GPU is capable of much higher frame rates, as evidenced by the 130 FPS at 1080p Low, but the CPU cannot sustain that performance at higher settings.

Q: What is the best resolution to play Thief with this combo?

A: 2560x1440 appears to be the optimal resolution. At 1440p High, the combo delivers 60 FPS, which is playable, and at 1440p Medium, it jumps to 78 FPS with a minimum of 66 FPS. At 1080p, the CPU bottleneck limits performance, and at 4K, the GPU struggles to maintain 60 FPS on any setting.

Q: How does the Arc B580 compare to the RTX 2080 in terms of benchmark scores?

A: The Arc B580’s average benchmark score is 23021, while the RTX 2080 has an average score of 22895. This puts the Arc B580 0.6% ahead of the RTX 2080, indicating they are nearly identical in raw compute performance, despite the Arc B580 being a newer architecture.

Q: Does the combo maintain 60 FPS at 4K with any settings?

A: Yes, but only at Low settings. At 3840x2160 Low, the combo averages 61 FPS. At Medium, it drops to 46 FPS, and at High or Ultra, it falls below 35 FPS, which is not ideal for a smooth experience.

Q: Is the Ryzen 5 4600G’s integrated graphics relevant in this pairing?

A: No. The CPU includes Radeon Vega 7 integrated graphics, but the system uses the discrete Arc B580. The integrated graphics are irrelevant for gaming performance in this configuration, as the data is measured with the discrete GPU.

Q: What is the CPU’s multi-threaded performance relative to its rivals?

A: The Ryzen 5 4600G has a cinebench_r23_multicore score of 13593. Its nearest rival, the AMD Ryzen 3 PRO 5355GE, has an average score that is 0.1% higher, while the Intel Core i3-14100T is 0.8% lower. This indicates the 4600G is competitive with these parts but does not stand out in multi-threaded workloads.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor based on the Zen 2 architecture, codenamed Renoir, built on a 7nm process. Its base clock is 3.70 GHz and boost clock is 4.20 GHz. The CPU has 8 MB of shared L3 cache and 512 KB of L2 cache per core. In Thief, this CPU is the primary bottleneck, particularly at 1080p. The game’s engine, from 2014, is likely single-thread dependent, and the 4600G’s single-thread performance, as measured by a 3dmark_single_thread score of 726, is below average for modern standards. This is reflected in the frame rates: at 1080p Low, the combo hits 130 FPS, but at 1080p High, it drops to 87 FPS, a 33% reduction that is more about CPU draw call overhead than GPU load.

The CPU’s multi-threaded performance is stronger, with a cinebench_r23_multicore score of 13593 and a passmark_multithread score of 15992. These scores indicate the CPU can handle background tasks and modern game engines that use multiple cores, but Thief’s engine does not benefit significantly from additional threads. The data shows that the CPU’s performance ceiling is reached at around 130 FPS in Thief at 1080p Low, and no amount of GPU headroom can push beyond that. The CPU’s memory bandwidth is also limited to 51.2 GB/s due to dual-channel DDR4 support, which can further constrain performance in a game that streams assets.

The CPU’s 65W TDP and unlocked multiplier suggest it is a power-efficient part, but its performance is simply not sufficient to fully utilize the Arc B580 in this title. The nearest CPU rivals, such as the AMD Ryzen 3 PRO 5355GE and Intel Core i3-14100T, show similar average scores, indicating that this is a general limitation of this performance tier, not a specific flaw of the 4600G. For Thief, the CPU role is clear: it sets a hard frame rate ceiling that prevents the GPU from delivering its full potential at lower resolutions.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo in Thief depend on the target resolution and desired frame rate. At 1080p, the CPU bottleneck means that increasing settings has a minimal impact on frame rate. The combo achieves 130 FPS at Low, 114 FPS at Medium, 87 FPS at High, and 83 FPS at Ultra. The jump from Low to Medium is only 16 FPS, while the jump from High to Ultra is just 4 FPS. This suggests that at 1080p, Medium settings offer the best balance, providing 114 FPS with a minimum of 97 FPS, which is a smooth experience. High settings are also playable at 87 FPS, but the marginal gain from Medium to High is not worth the 27 FPS loss.

At 1440p, the GPU becomes more involved, and the settings scaling is more pronounced. Low settings produce 103 FPS, Medium produces 78 FPS, High produces 60 FPS, and Ultra produces 57 FPS. The sweet spot here is High settings, which delivers 60 FPS, a common target for smooth gameplay. Medium settings at 1440p also work well at 78 FPS, but High offers better visual quality at the same playable frame rate. Ultra is not recommended at 1440p, as the 57 FPS average is close to the 60 FPS target but may dip below in heavier scenes.

At 4K, the GPU is the limiting factor, and settings must be reduced significantly. Low settings average 61 FPS, which is playable, but Medium drops to 46 FPS, which is not ideal for a stealth game requiring precision. High and Ultra settings, at 35 FPS and 33 FPS respectively, are not recommended for gameplay. The best experience at 4K is Low settings, which maintains a playable 61 FPS, though the visual quality will be noticeably reduced. For most users, 1440p High is the recommended configuration, as it balances visual fidelity with a consistent 60 FPS, while 1080p Medium offers the highest frame rates for competitive play.
