Thief

The pairing of a flagship Intel Core i7-14700K with the mid-range AMD Radeon RX 580 produces frame rates in Thief that are entirely bound by the GPU, yielding a combination ranked 3,397th out of 3,720 tested. In the measured rows, Low settings at 1080p average 83 FPS, but the frame rate craters to 33 FPS at 4K Low, showing the RX 580 as the decisive bottleneck even with a 94th-percentile CPU driving it.

Resolution Scaling

Thief's measured FPS across resolutions follows a pattern that clearly isolates the graphics card as the limiting component. At Low preset, the average frame count falls from 83 FPS at 1920x1080 to 57 FPS at 2560x1440 and then to 33 FPS at 3840x2160. The High preset shows a steeper relative decline: 48 FPS at 1080p, 33 at 1440p, and 19 at 4K. Medium, which provides the only trio with min and max values, drops from 63 FPS (min 54, max 72) at 1080p to 43 (min 37, max 50) at 1440p and 25 (min 22, max 29) at 4K. Ultra follows the same slope: 46 FPS at 1080p, 31 at 1440p, and 18 at 6K.

The consistent downward shift with every step in resolution indicates that the system is GPU-bound. A CPU-limited configuration would show far less such divergence between resolutions — the i7-14700K's 20 cores and 28 threads and its boost clock of 5.60 GHz hold far more throughput than any single-game engine from 2024 requires. Since the FPS scales in near-ratio to the pixel count, the efficient strategy is to attribute the drop to the RX 580's limited shader and memory bandwidth rather than to the CPU.

CPU Role

The Core i7-14700K is a high-end desktop chip with 20 cores and 28 threads, a base clock of 3.40 GHz, and a boost clock of 5.60 GHz. Its benchmark scores place it in the 94th percentile among all CPUs, with an average benchmark score of 69,355. Its nearest competitors—AMD EPYC 9115 (average 69,288), Ryzen 9 7950X (69,515), Ryzen 9 7940HX (69,875), and Ryzen 7 9700F (69,996)—are all within a fraction of a percent, so the i7-14700K is firmly at the top of the performance stack.

In Thief, however, that raw CPU power is largely unexploited. When moving from 1080p Low to 4K Low, the frame rate drops from 83 to 33, and from 1080p Ultra to 4K Ultra, the average falls from 46 to 18. There is no point where the CPU could be the limiting component—such a scenario would show far less change with resolution. The CPU's attributes (cache, L3, multi-core scores) are abundant for a stealth game that primarily utilizes a few threads. The measured results show that even at 1080p Medium, the FPS still holds at 63, which is far below what the CPU would be able to feed if the GPU weren't the constraint.

The pairing is thus a textbook case of a high-end CPU being wasted on a medium-range GPU. The i7-14700K's multi-core capabilities, for example, are demonstrated by Cinebench R23 multi-thread score of 33,440.5, and a Geekbench multi-core score of 20,767; Thief's per-thread load is not enough to utilize any of that scaling, but the GPU's render limits cap every settings level.

Settings Recommendations

Based on the measured rows, the most practical balance is 1080p Medium. The average 63 FPS with a reported minimum of 54 ensures a relatively stable experience, double the 83 FPS at Low involves sacrificing visual quality that Masht is to be achieved at maxima. High at 1080p yields 48 FPS—adequate but lower—and Ultra drops to 46, so High and Ultra are nearly equal, both below the 60 FPS threshold that would be comfortable for a stealth game.

At 1440p, the picture changes only modestly. Low captures 57 FPS, Medium 43 (min 37, max 50), High 33, Ultra 31. If the user prefers the higher panel, 1440p Low is the only setting that approaches what could be considered fluid, but typing in the avg of 57, just short of a lock to 60. For users who accept lower average frame rates, 1440p Medium still yields 43 FPS, but 4K excludes any option that maintains consistent 30 FPS: 4K Low at 33, 4K Medium at 25, 4K High at 19, Ultra at 18.

The decision matrix is: 1080p Medium delivers the best trade-off between quality and frame rate based on the measured numbers; 1440p Low is the highest resolution at which an average above 50 is seen. 4K is unsuitable for playable rates under these settings.

How This Combo Ranks

In the database's ranking for Thief, this specific CPU-GPU pair sits at 3,397 out of 3,720 tested combos. That places it in the bottom segment of the entire sampling. Consider that the i7-14700K alone is in the 94th percentile of CPUs, meaning it is faster than 94% of all processed in the database. The RX 580, however, stands only in the 53rd percentile of GPUs, exactly mid-pack. The low total rank is a direct result of the GPU being an old, mid-range part from 2017 (release date 2017-04-17). In a game like Thief, which is eight years older than the GPU (the game is from 2014-02-24), the GPU's workload is still too heavy for a card that is generations behind.

The rank is 3397, leaving 236 slots lower (3720-3397=323) — these few combos below it likely use even weaker GPUs. That the RX 580 is placed at the 53rd percentile among all GPUs, yet the combo still sits in the bottom 90th percentile (since it's ~3397 out of 3720 – we don't have an exact percentage but it’s below the 10th percentile), highlights how much CPU strength does not compensate for a grahics card that is no longer entry-level. The average GPU benchmark score of 12,928, which is similar to GTX 1660 SUPER and RTX 3050 Ti Mobile, confirms that level is the primary limiter.

GPU Role

The AMD Radeon RX 580 is a mid-range GPU from 2017 with 8 GB of GDDR5 memory on a 256-bit bus, delivering a bandwidth of 256.0 GB/s. Its shading units number 2,304, with 144 TMUs and 32 ROPs, and a 6.175 TFLOPS FP32 compute figure. The base clock is 1,257 MHz and boost is 1,340 MHz. Its record shows it sits at the 53rd percentile among all GPUs, with specifications that put it directly alongside GeForce GTX 1660 SUPER (score 12,986) and RTX 3050 Ti Mobile (12,940) – within ~0.4% of both.

In Thief, the GPU's limits are decisive. The pass of a large pixel fill rate (42.88 GPixel/s) and the memory bandwidth of 256 GB/s are not enough to maintain high frame rates at modern resolutions. The FPS data at 4K (average 18–33) and the drop from 83 to 33 across Low settings between 1080p and 4K directly reflect the GPU workload. The RX 580 also supports DirectX 12_0, OpenGL 4.6, and Vulkan 1.3, which covers the game’s API, but the underlying architecture (GCN 4.0 on Polaris 20) is now old.

The measured FPS numbers show that the GPU is the single point of failure: even the lowest settings at 1440p do not reach a consistent 60 FPS. The RX 580's VRAM of 8 GB is sufficient for Thief, and the memory bus only 256-bit, but the core architecture cannot process the shading work. The fact that the card uses only 185W (TDP) and a suggested 450W PSU is irrelevant to the performance ceiling seen here. The frame rate scaling with preset quality confirms it: enabling Ultra at 1080p reduces the frame rate from 83 to 46, a 37 FPS hit—a sign that texture/shader workloads are only moderate, but the homogeneous feature of the GPU is still not enough for high preset.
