Thief

The Intel Core i9-14900K paired with an AMD Radeon RX 580 produces some of the lowest frame rates in our measured database for Thief, a stealth title released on 2014-02-24. Despite the CPU's massive 24 cores and 32 threads, the RX 580 clearly dictates the playable experience, with average FPS ranging from 18 at 4K Ultra to 83 at 1080p Low. The data shows a GPU-bound scenario where the modern, top-tier processor cannot compensate for the older Polaris card. This pairing lands near the bottom of our tested combinations, ranking 3397th out of 3720, a position that reflects the GPU's limitations rather than the CPU's strengths. Below we break down the optimal settings, the roles of each component, and answer the most common questions.

Settings Recommendations

Given the measured FPS across all four presets, Medium is clearly the best preset for this combination. It is the only setting with recorded minimum and maximum values, which indicate stable frame pacing: at 1080p Medium you get 63 FPS with a 54–72 range, at 1440p it sits at 43 with a 37–50 range, and at 4K it falls to 25 with a 22–29 range. These numbers show that Medium offers the best blend of visual quality and sustained performance, especially when you consider that the next step up, High, delivers 48, 33, and 19 FPS at the same resolutions—a significant drop that yields little visual benefit for a frame rate loss of about 31–29% from Medium. The Ultra preset adds almost nothing: at 1080p it gives 46 FPS, only 2 FPS faster than High, and at 4K it is the worst with 18 FPS.

If you require 4K, the data suggests dropping to Low, which hits 33 FPS at 3840x2160. That’s playable if you have no display speed requirement, but it can’t reach the 60 FPS mark. For 1440p, Medium at 43 FPS is acceptable; Low offers 57, but the visual downgrade may not be worth it. For 1080p, Medium is the responsible choice — it stays above 50 FPS even in the worst moments, and the 83 FPS on Low is not enough to justify the loss of detail since 63 FPS is already a strong number. In summary, choose Medium for any resolution; you just won’t get a 4 display experience above 33 FPS.

GPU Role

The AMD Radeon RX 580 uses the Polaris 20 chip on the GlobalFoundries 14 nm process, with 8 GB of GDDR5 memory on a 256-bit bus, yielding a 256.0 GB/s bandwidth. Its GPU clocks are modest by today’s standards: a base of 1257 MHz and a boost of 1340 MHz. With 2304 shading units, 144 texture units, and 32 ROPs, it can generate a pixel fill rate of 42.88 GPixel/s and a texture fill rate of 193.0 GTexel/s. These numbers confirm a mid-range card that was designed for 1080p gaming at 60 FPS when released in 2017. In Thief, these specs translate directly to the observed FPS: the GPU is the sole limiter at every resolution.

The 8 GB VRAM is more than sufficient for Thief, even at 4K, but the card’s raw processing power—6.175 TFLOPS FP32—cannot handle the load of the higher presets. The measured FPS demonstrates this: at 4K Ultra, the card only produces 18 FPS, and the difference between Low and Ultra is 15 FPS (33 vs 18), showing that the game expands GPU workload with settings, which the Polaris architecture cannot sustain. The card sits at the 53rd percentile when compared to all other GPUs historically, and its average benchmark score of 12928 is essentially tied with the NVIDIA GeForce RTX 3050 Ti Mobile (-0.1% delta) and the GTX 1660 SUPER (-0.4%).

The technological gap is clear: the RX 580 has a base clock 1257 MHz and a boost of 1340 MHz, but even pushing the boost it has only 193.0 GTexel/s of texture throughput. At 4K, the pixel load exceeds this card’s capabilities, causing the FPS to sink to the low 20s. The fix is not in VRAM—8 GB is fine for this 2014 title—but in the core engine. The GPU’s role in this combo is the defining one; a weaker CPU would not change the numbers nearly as much as this GPU’s performance limits the experience.

How This Combo Ranks

In the overall database, this Intel Core i9-14900K + Radeon RX 580 combination holds rank 3397 out of 3720 tested configurations for Thief. That places it in the 8.7% percentile—meaning only 323 other combos perform worse. Its rank is not a surprise: swap the CPU for a much cheaper chip, and this GPU would still be the constraining factor in the numbers. The ranking shows that the list is heavily skewed toward modern mid-range and high-end GPUs; the RX 580 is simply an older, lower-performance card for long-term sustained FPS.

A notable about the rank is that this is one of the few tests where the CPU’s massive theoretical strong position does nothing to help the score. In other games, the i9-14900K’s 95th percentile CPU score (average benchmark score 79098) bolsters the combo’s standing, but Thief cares only about rasterization speed. Even the nearest rival GPUs—like the RTX 3050 Ti Mobile (delta -0.3%)—produce similar FPS, which again confirms that the GPU is the weak link. The overall ranking tells the story: this is a build for playing at 1080p, not for pushing higher resolutions.

FAQ

Q: What is the best preset to use at 1920x1080 with the RX 580 and i9-14900K?

A: Medium is the sweet spot. It achieves 63 FPS on average with a minimum of 54 and a maximum of 72, while Low is only 83 FPS but with reduced visual fidelity, and High/Ultra drop to 48 and 46 respectively. Medium is the only preset that stays near the 60 FPS target without sacrificing very much.

Q: Can this combo run Thief at 3840x220?

A: Not really. The highest FPS at 2160p is the Low preset at 33 FPS, while Medium produces 25, High 19, and Ultra only 18. None of these reach a smooth 60 FPS, and even the top value 33 is at the edge of playability. So 4K is effectively not playable with this GPU.

Q: How stable is the FPS when using the Medium preset?

A: Medium has complete frame time data. At 1080p, the range is 54–72 FPS; at 1440p, 37–50; at 4K, 22–29. This indicates a relatively consistent frame experience with some fluctuation at lower resolutions, and tight minimums at higher resolutions.

Q: What is the role of the CPU in this game?

A: The Intel Core i9-14900K has 24 cores, 32 threads, base 3.20 GHz, and boost boost MHz6.00. Even in Thief, a 2014 title, the CPU is far from the limit. Its multi-core performance of 39399.5 in Cinebench R23 and single-core 2262.5 show it far exceeds the demands of this engine. The measured FPS pattern (sharp drops with resolution) proves that the RX 580 is the bottleneck, not any CPU limitation.

Q: How does this RX 580 compare to its closest rivals in the GPU benchmark list?

A: In general performance, it essentially equals the NVIDIA GeForce RTX 3050 Ti Mobile and GTX 1660 SUPER, with deltas of -0.1% and -0.4% respectively. That places the RX 580 around in the middle of all GPUs at the 53rd percentile, which is quite modern for 2017, but not good enough for today's high-frame-rate demands at higher resolutions.

Q: Is the 8GB VRAM of the RX 580 enough for Thief?</strong>

A: The 8 GB GDDR5 with 256.0 GB/s bandwidth is more than sufficient for Thief. Even at 4K Ultra, no VRAM bottleneck shows, as the frame rates are low due to the GPU’s compute power, not because of memory capacity. The game from 2014 will easily fit in 8 GB.

Resolution Scaling

The FPS data reveals a steep and consistent relationship between internal resolution and performance. At Medium quality, the average frame rate shifts from 63 FPS at 1920x1080 to 43 FPS at 2560x1440 and then to 25 FPS at 3840x2160. Down from Low settings, you go from 83 to 57 to 33; High drops 48 to 33 and 19; Ultra goes 46 to 31 to 18. The pattern is clear: each jump from 1080p to 1440p makes about a 30% performance hit, and each jump from 1440p to 4K adds an even more obvious drop.

This large change with resolution is characteristic of a GPU bound. The RX 580’s bring factors like its 42.88 GPixel/s pixel rate and 6.175 TFLOPS are being fully utilized by the processing load of 4K. The CPU’s Intel UHD 770 is not even a part of—the discrete GPU does all the work. Because the data shows consistently that higher resolutions still use the same pattern across all four quality settings, the limiting hardware is clearly the Radeon RX 580. A user who plays at 1280p can expect a playable 60 FPS, while at 1440p that smoothness is lost, and at 2160p only the low preset manages above 30.

CPU Role

The Intel Core i9-14900K is not the bottleneck in this beta test. Its 24 cores/32 threads, a base clock of 3.20 GHz and boost up to 6.00 GHz, and 36 MB of L3 cache are overkill for Thief, a 2014 game. The evidence is in the benchmarking data: the CPU’s multi-core performance (39399 in Cinebench R23, 20793 in R20) and single-core (2262 in R23) are excellent in theoretical tests, but the game’s FPS do not move in concert with those numbers. At 1080p Low, the game manages 83 FPS, and at 1440p High it drops to 33—neither of which is a CPU-stable number. The GPU’s performance limit is what shapes all the low.

When you examine the data from a low (83) to a high (48) at 1080p, the spread of 35 FPS is wide and consistent with the GPU’s cheap ability to handle different settings. Even the two ryzen and core extreme CPU features do not change this. The CPU’s role is to feed the GPU with data, but since RX 580 is easy to saturate, the i9-14900K is likely operating well below its capacity. This confirms a design tip: if you already have an RX 580, investing in a high-end CPU like the i9-14900K delivers no extra FPS in Thief. Instead, the money is better spent on a modern GPU such as a GT 1660 SUPER (its nearest equal in the benchmark) or something to overcome the 53rd percentile barrier. The CPU stands ready, but the GPU is the weak link, and the frame rates reflect that.
