Thief

The AMD Ryzen 5 5600X paired with Intel's Arc B580 is an asymmetric combination: a 2020 Zen 3 six-core sitting in the 75th percentile of all tested CPUs, and a 2024 Battlemage GPU in the 68th percentile of all GPUs. Against Thief, a stealth title released in February 2014, that pairing lands at rank 2814 of 3720 tested combinations in this game — mid-pack in ranking terms, but the raw frame rates tell a story of comfortable playability at 1080p and 1440p, with 4K being the one genuine struggle.

Measured FPS Breakdown

All figures below are measured averages from this exact pairing, ranked preset by preset.

At 1920x1080, the combo is fast across the board. Low settings deliver 147.7 FPS, Medium climbs down to a still-high 112.4 FPS, High holds 87.7 FPS, and even Ultra keeps an 81.5 FPS average. That is the headline: at 1080p, there is no preset in the test suite that drops the average below 60 FPS — in fact none drops below 80.

At 2560x1440, the numbers compress but stay usable. Low returns 102.4 FPS, Medium 80.8 FPS, High 58.6 FPS, and Ultra 57.2 FPS. Note the narrow gap between High and Ultra at this resolution — less than one and a half frames separates them — which suggests the GPU is the limiting factor here rather than the preset choice mattering much at the top end.

At 3840x2160, the walls close in. Low manages 59 FPS, a hair short of the 60 FPS playable threshold. Medium averages 48.4 FPS, High 35.8 FPS, and Ultra 30.5 FPS. Minimum and maximum frame rates were not recorded for these runs, so the averages are the full picture — but none of the 4K presets clear the bar, and the Low-preset result at 59 FPS is close enough that real-world dips would likely dip below it.

A pattern worth noting: the drop from 1080p to 1440p costs roughly 30% of the frame rate at every preset (Ultra goes from 81.5 to 57.2, Medium from 112.4 to 80.8), and the drop from 1440p to 4K costs a similar proportion again. That consistent, proportional scaling is the signature of a GPU-bound game.

CPU and GPU Roles

The data points clearly to the Intel Arc B580 as the component doing the heavy lifting in Thief. Evidence one: frame rates scale almost perfectly with resolution. At Ultra, the average falls from 81.5 FPS at 1080p, to 57.2 FPS at 1440p, to 30.5 FPS at 4K — each resolution step roughly halving the pixel-pushing headroom and the frame rate following it down. If the Ryzen 5 5600X were the bottleneck, raising the resolution would flatten the curve, because the CPU workload barely changes between 1080p and 4K. It does not flatten.

Evidence two: preset scaling within a fixed resolution. At 1080p, the spread between Low (147.7 FPS) and Ultra (81.5 FPS) is large and orderly, which means the game is responding directly to graphics load. A CPU-limited configuration would show presets clustered together at a ceiling, and that clustering only begins to appear at 1440p High/Ultra and dominates at 4K.

What does the 5600X contribute? Headroom. With a Cinebench R23 single-core score of 1541, a multi-core score of 11838, and a 3DMark single-thread score of 917, this Zen 3 part sits in the 75th percentile of all CPUs in the database — well above what a 2014 stealth game demands. Thief shipped years before this CPU existed, and the 12 threads and 4.60 GHz boost clock give it ample margin. The practical takeaway: at 1080p Medium and below, where the average exceeds 110 FPS, the CPU is doing its part without strain, and there is no indication from this data of a processor-side ceiling at any tested resolution.

Similar Performance Alternatives

For the CPU, the database's nearest rivals to the Ryzen 5 5600X are effectively interchangeable in aggregate benchmark terms. The AMD Ryzen 7 4800H sits within 0.1% of its average score, while the AMD Ryzen 5 PRO 6650U, Intel Core i7-11700, and AMD EPYC 9554P all fall within roughly half a percent either direction. Anyone running one of those processors alongside an Arc B580 should expect Thief to behave essentially the same as it does here — the deltas are small enough to vanish inside normal run-to-run variation.

For the GPU, the picture is more interesting because the Arc B580's rivals span different eras. The AMD Radeon RX 580 2048SP matches it within 0.2% on average score, the NVIDIA GeForce RTX 2080 sits 0.6% behind, the RTX 3080 is 0.7% ahead, and the NVIDIA P106-100 is 1% ahead. In practice, that means an RTX 2080 or RTX 3080 system should produce Thief frame rates within a frame or two of this configuration at each resolution and preset, and the older RX 580 2048SP should land close as well — a useful data point given how common that card remains in the wild.

Swapping both components for their nearest rivals would, on the aggregate numbers, reproduce this configuration's behavior. The B580's raw credentials — 2560 shading units, 13.67 TFLOPS of FP32, 12 GB of GDDR6 on a 192-bit bus with 456 GB/s of bandwidth — line up with those rivals' aggregate scores, and Thief does not stress any of them hard outside of 4K.

How This Combo Ranks

Within Thief specifically, this pairing ranks 2814 out of 3720 tested combinations. Taken at face value, that places it in the bottom third of the field — but rank position in a database like this is skewed by the number of high-end combinations tested against an older title. The absolute numbers matter more: 81.5 FPS at 1080p Ultra and 80.8 FPS at 1440p Medium are strong results for any single-player stealth game, where a stable 60 FPS is the whole objective.

The percentile context reinforces this. The 5600X sits in the 75th percentile of all CPUs; the Arc B580 in the 68th percentile of all GPUs. Both are above-median parts, and the measured data shows them delivering above-threshold performance at two of the three tested resolutions. The rank of 2814 reflects the depth of the leaderboard, not a deficiency in this pairing's actual experience of the game.

The Verdict

Yes — this PC runs Thief, with one clear caveat about resolution.

At 1920x1080, every tested preset clears 60 FPS: Low at 147.7, Medium at 112.4, High at 87.7, and Ultra at 81.5. The verdict data flags Ultra as the best playable setting at this resolution, meaning there is no reason to compromise on visuals at 1080p.

At 2560x1440, Low (102.4 FPS) and Medium (80.8 FPS) are the playable settings, with Medium flagged as the best. High (58.6 FPS) and Ultra (57.2 FPS) miss the threshold narrowly — close enough that a slightly more capable GPU, or a resolution scaling tweak, would likely push them over, but on measured averages alone they do not qualify.

At 3840x2160, nothing qualifies. Low's 59 FPS average is the closest, a single frame short of the 60 FPS threshold, and Medium through Ultra fall well behind. 4K gaming on this hardware in Thief means accepting sub-60 frame rates across the board.

The practical recommendation is straightforward: play at 1080p Ultra or 1440p Medium. Both deliver averages above 80 FPS with settings maximized or near-maximized for the resolution, and the Ryzen 5 5600X provides enough CPU margin that neither configuration is at risk of a processor-side bottleneck.

FAQ

Q: Can the Ryzen 5 5600X and Arc B580 run Thief at 4K?

A: Not at the 60 FPS playable threshold. Low settings average 59 FPS, Medium 48.4, High 35.8, and Ultra 30.5 — no preset clears the bar at 3840x2160.

Q: What is the best way to play Thief on this PC?

A: 1920x1080 at Ultra, which averages 81.5 FPS. If you prefer a higher resolution, 2560x1440 at Medium averages 80.8 FPS and is flagged as the best playable setting there.

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

A: The GPU. Frame rates scale down consistently as resolution rises — Ultra drops from 81.5 to 57.2 to 30.5 FPS across the three resolutions — which is classic GPU-bound behavior. The 5600X, in the 75th percentile of all CPUs, has ample headroom for this title.

Q: Would a different GPU give similar performance in this game?

A: Yes. The nearest rivals to the Arc B580 — the Radeon RX 580 2048SP (within 0.2%), GeForce RTX 2080 (0.6% behind), RTX 3080 (0.7% ahead), and P106-100 (1% ahead) — should all produce Thief results within a narrow margin of this configuration.

Q: How does this combination rank against other tested setups in Thief?

A: It ranks 2814 of 3720 tested combinations in this game. The absolute frame rates remain strong at 1080p and 1440p despite the mid-pack ranking.

Q: Does High or Ultra matter at 1440p?

A: Barely. High averages 58.6 FPS and Ultra 57.2 FPS — under one and a half frames apart — and both miss the 60 FPS threshold, so Medium at 80.8 FPS is the sensible choice at that resolution.
