Thief

Thief, a 2014 stealth title built on the Unreal Engine 3-derived “Splash Damage” engine, responds predictably but not uniformly to the Intel Core i7-14700K and AMD Radeon RX 6800 XT pairing. The measured frame rates show a clear hierarchy where resolution and preset choices dictate whether the CPU or GPU becomes the bottleneck. This combination is a strong match for the game, but the data reveals exactly where each component’s influence peaks, and where the GPU’s raw throughput takes over.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep but consistent, indicating a shift in workload from the processor to the graphics card. At Low settings, the average FPS falls from 218.9 at 1920x1080 to 96.4 at 3840x2160—a reduction of roughly 56%. This massive drop at the lowest preset is a classic sign that the CPU is no longer the limiting factor; instead, the GPU’s pixel-pushing capabilities are being taxed heavily. The same trend appears at Medium and High settings, where the 4K averages (72.1 and 55.1, respectively) are about 60% lower than their 1080p counterparts (178.6 and 134.6).

The scaling from 1440p to 4K is also notable. At High settings, 2560x1440 yields 95.9 FPS, while 3840x2160 dips to 55.1 FPS—a 43% loss. This is a larger relative drop than what you’d see between 1080p and 1440p, where High settings only lose about 29% of performance (134.6 to 95.9). The pattern suggests that at 4K, the RX 6800 XT is working near its limits, and the game’s geometry and lighting effects at higher presets amplify the GPU load. At 1080p, the high frame rates (218.9 at Low, 178.6 at Medium) indicate the Core i7-14700K has ample headroom to feed the GPU, meaning the CPU is not a constraint until you push resolution down and settings up.

How This Combo Ranks

In the database of tested combinations, this pairing sits at rank 376 out of 1642 combos for Thief. That places it in the top 23% of all tested systems, which is a strong showing for a game that is over a decade old. The rank reflects a balanced setup that can handle the game’s highest presets at playable frame rates, even at 4K. The combo’s position is not surprising given the hardware’s generational strengths: the CPU’s high single-thread performance and the GPU’s substantial memory bandwidth.

The ranking also implies that many other combinations—likely featuring newer or more expensive GPUs—achieve higher raw frame rates, but this pairing’s consistency across resolutions is its key asset. For a stealth game where smooth, tear-free movement matters more than extreme FPS, being in the 376th spot out of 1642 is more than adequate. It outperforms the majority of systems tested, and the measured data confirms that the bottleneck is rarely the CPU, which is a common issue with older titles.

GPU Role

The AMD Radeon RX 6800 XT is the dominant component in this pairing for Thief, especially at higher resolutions. Its 16 GB of GDDR6 memory on a 256-bit bus provides 512.0 GB/s of bandwidth, which is crucial for the game’s texture streaming at 4K. The GPU’s boost clock of 2250 MHz (with a game clock of 2015 MHz) allows for strong sustained performance, as seen in the 4K Ultra result of 55.2 FPS—nearly identical to the 4K High result of 55.1 FPS. This suggests that at 4K, the GPU is saturated regardless of whether you choose High or Ultra, as the extra settings overhead does not yield a measurable frame rate difference.

The GPU’s 128 ROPs and 288 TMUs handle the game’s lighting and shadow rendering effectively. The measured data shows that at 1440p Ultra, the card delivers 91.6 FPS, which is a 5% drop from High (95.9 FPS), indicating that the Ultra preset’s added effects (like higher-quality shadows) do not cripple the card. The GPU’s 20.74 TFLOPS of FP32 compute is more than enough for this title, which was designed for hardware from 2014. The 4K Low result of 96.4 FPS confirms that the card can push high refresh rates even at the most demanding resolution when settings are reduced.

Measured FPS Breakdown

At 1920x1080, the combo delivers high frame rates across all presets. Low settings average 218.9 FPS, Medium 178.6 FPS, High 134.6 FPS, and Ultra 128.7 FPS. The gap between High and Ultra is only 5.9 FPS, suggesting that the Ultra preset’s marginal visual improvements come at a minimal cost to performance. At 2560x1440, the averages are 162.4 FPS (Low), 121.9 FPS (Medium), 95.9 FPS (High), and 91.6 FPS (Ultra). The 1440p results show a more pronounced drop from Low to Ultra—about 44%—which is expected as the GPU begins to work harder.

At 3840x2160, the frame rates are 96.4 FPS (Low), 72.1 FPS (Medium), 55.1 FPS (High), and 55.2 FPS (Ultra). The Ultra result being slightly higher than High is within measurement variance, but it confirms that the GPU is the bottleneck at 4K. The jump from Low to Medium at 4K costs 24.3 FPS, while the jump from Medium to High costs 17 FPS—showing diminishing returns as the GPU approaches its limit. The 4K Low result of 96.4 FPS is the only 4K preset that exceeds a 60 FPS target, which is important for players with 4K displays who want smoother gameplay.

FAQ

Q: Can this combo run Thief at 4K with playable frame rates?

A: Yes, but only at Low settings, where the average FPS is 96.4. At Medium, it drops to 72.1 FPS, and at High or Ultra, it falls to 55.1-55.2 FPS, which is below a 60 FPS target.

Q: Is the CPU or GPU the limiting factor at 1080p?

A: The data shows the CPU is not a bottleneck at 1080p. The lowest frame rate at 1080p is 128.7 FPS (Ultra), which is far above the refresh rate of most monitors, indicating the GPU is handling the load with CPU headroom to spare.

Q: What is the difference between High and Ultra settings at 1440p?

A: The measured difference is small: High averages 95.9 FPS, while Ultra averages 91.6 FPS, a 4.3 FPS gap that is unlikely to be noticeable in gameplay.

Q: How does the RX 6800 XT’s memory affect performance?

A: The 16 GB of GDDR6 memory with 512.0 GB/s bandwidth ensures that texture streaming at 4K does not cause stuttering, as evidenced by the consistent frame rates across 4K presets.

Q: Is this combo better suited for 1440p or 4K gaming in Thief?

A: The data favors 1440p, where all presets exceed 90 FPS, including Ultra at 91.6 FPS. At 4K, only Low settings provide a comfortable frame rate above 60 FPS.

Q: Does the GPU’s boost clock matter for this game?

A: The boost clock of 2250 MHz helps maintain high frame rates, but the game is more dependent on memory bandwidth and ROP throughput, as shown by the small performance difference between High and Ultra at 4K.

CPU Role

The Intel Core i7-14700K plays a supporting role in Thief, but its capabilities are what allow the GPU to reach its full potential at lower resolutions. With 20 cores and 28 threads, the CPU has massive multi-threading headroom, but Thief is not a heavily threaded title. The measured frame rates at 1080p—particularly the 218.9 FPS at Low—show that the CPU’s single-core performance is sufficient to feed the GPU without creating a bottleneck. The CPU’s boost clock of 5.60 GHz and base clock of 3.40 GHz ensure that even the game’s most demanding scripted sequences do not cause frame dips.

The CPU’s 33 MB of shared L3 cache is beneficial for this game’s level streaming, reducing the likelihood of hitches when moving between areas. The benchmark results for the i7-14700K show a multicore score of 44534 in Cinebench R23 and a single-core score of 6287, which places it in the 96th percentile of all CPUs. This headroom means that even with background tasks running, the CPU can maintain the high frame rates seen in the 1080p and 1440p tests. At 4K, the CPU’s role diminishes, as the GPU becomes the clear limiter—the 4K results hover around 55 FPS regardless of High or Ultra settings, confirming that the processor is not holding back the graphics card. For players with high-refresh-rate 1080p or 1440p monitors, this CPU-GPU pairing provides a smooth experience, with the CPU ensuring that frame times remain consistent even during intense stealth gameplay moments.
