Thief

Thief, a 2014 stealth title, proves surprisingly demanding when paired with the Intel Core i5-14600K and AMD Radeon RX 6700 XT. This combination delivers playable frame rates across most settings, but the data reveals a clear shift in system bottleneck as resolution and graphical fidelity change. The measured results show a config that is capable of high-refresh-rate 1080p gaming but begins to strain under the load of 4K Ultra.

Resolution Scaling

The performance drop from 1080p to 4K is substantial, highlighting the increasing pressure placed on the GPU at higher resolutions. At Low settings, the average frame rate falls from 185.2 FPS at 1920x1080 to 73.2 FPS at 3840x2160, a reduction of 112 FPS. This significant scaling factor indicates that at lower settings, the system is heavily reliant on the graphics card to maintain output, and the transition to 4K quadruples the pixel count, causing a dramatic dip in performance.

Moving to High settings, the drop is less severe in absolute terms but still considerable, with the average frame rate decreasing from 109.6 FPS at 1080p to 45.2 FPS at 4K. The trend continues with Ultra settings, where the frame rate falls from 102.6 FPS at 1080p to a barely playable 41.6 FPS at 4K. The data suggests that at 1080p, particularly with lower settings, the CPU has enough headroom to feed the GPU, but as resolution climbs, the GPU becomes the limiting factor, causing frame rates to plummet.

The scaling pattern points to a system where the RX 6700 XT is the primary constraint at 4K. The gap between Low and Ultra settings at 1080p is 82.6 FPS, but at 4K, this gap narrows to just 31.6 FPS. This compression of performance across settings at higher resolutions is a classic sign of a GPU bottleneck, where the graphics card’s processing power, rather than the game’s settings, dictates the final frame rate. The 4K results show a range from 41.6 FPS to 73.2 FPS, all of which are below the ideal for smooth gameplay, indicating the GPU is saturated.

GPU Role

The AMD Radeon RX 6700 XT is built on the RDNA 2.0 architecture and features 12 GB of GDDR6 memory on a 192-bit bus, providing a memory bandwidth of 384.0 GB/s. Its high boost clock of 2581 MHz and base clock of 2321 MHz are key to its performance. The card’s 2560 shading units and 64 ROPs are responsible for pixel processing, and its 13.21 TFLOPS of FP32 compute power is a strong indicator of its raw capability.

In Thief, the GPU’s role is most evident in the resolution scaling. The card’s performance in the benchmark suite, where it scores 19786 in Passmark G3D, places it in the 77th percentile of all GPUs. Its average benchmark score of 33721 puts it in close competition with the AMD Radeon RX 6800, which scores 33493, a delta of just 0.7%. This close rivalry suggests that while the RX 6700 XT is a competent performer, it is not at the top of its class, and its limits are exposed at 4K resolution.

The 12 GB VRAM capacity is not a limiting factor in these tests, as even at 4K Ultra, the game’s requirements are met without issue. The GPU’s memory clock of 2000 MHz and effective speed of 16 Gbps contribute to the high bandwidth necessary for high-resolution textures. However, the data shows that the card’s compute capabilities are the bottleneck at 4K, as the average frame rates drop below 60 FPS for all settings except Low. The GPU’s 230 W TDP and suggested 550 W PSU are standard for this class, but the performance ceiling is clearly defined by its position relative to the RX 6800.

CPU Role

The Intel Core i5-14600K is a 14-core, 20-thread processor from the Raptor Lake architecture, with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. It features a large 24 MB shared L3 cache and supports both DDR4 and DDR5 memory. Its performance in synthetic benchmarks is strong, with a Cinebench R23 multi-core score of 32881 and a single-core score of 4642, placing it in the 93rd percentile of all CPUs.

In Thief, the CPU’s influence is most apparent at lower resolutions and settings. At 1080p Low, the system achieves 185.2 FPS, a frame rate that is likely CPU-bound, as the GPU is not fully utilized. The processor’s high single-thread performance, evidenced by its Passmark single-thread score of 4270, is crucial for maintaining high frame rates in a game from 2014, which may not be optimized for many cores. The data suggests that the i5-14600K has ample headroom to keep up with the GPU at 1080p, ensuring that the graphics card is the limiting factor even at high settings.

The CPU’s multi-core strength, with a Passmark multi-thread score of 38682, is less relevant in this title, as Thief’s engine likely relies on fewer threads. The processor’s nearest rival, the AMD Ryzen 9 5950X, scores 49062 in average benchmarks, a delta of just 0.2%, indicating that the i5-14600K is a top-tier performer. This raw power means that at 1440p, the CPU is unlikely to cause any frame rate drops, and the GPU remains the primary constraint, as seen in the 76.5 FPS High and 73.6 FPS Ultra results at this resolution.

Measured FPS Breakdown

At 1920x1080, the system demonstrates its peak performance, with all settings delivering playable frame rates. Low settings yield an average of 185.2 FPS, while Medium produces 140.1 FPS and High reaches 109.6 FPS. Ultra settings are still smooth at 102.6 FPS. This resolution is clearly where the RX 6700 XT and i5-14600K work best together, providing a high-refresh-rate experience even at maximum quality.

Moving to 2560x1440, the frame rates remain solid but show the expected decline. Low settings drop to 125.7 FPS, Medium to 96.3 FPS, High to 76.5 FPS, and Ultra to 73.6 FPS. All of these are above 60 FPS, making 1440p a viable resolution for this combination, with High and Ultra settings still providing a smooth experience. The performance gap between 1080p and 1440p is noticeable, with a roughly 30% reduction in frame rate across most settings.

At 3840x2160, the GPU’s limitations are fully exposed. Low settings manage an average of 73.2 FPS, but Medium drops to 55.8 FPS, High to 45.2 FPS, and Ultra to 41.6 FPS. Only Low settings are consistently above 60 FPS, while Medium is borderline. High and Ultra settings are below the 60 FPS threshold, making for a less fluid experience. The data shows that 4K is only suitable for this hardware when graphical settings are reduced to Low, and even then, the frame rate is not as high as one might hope for a game from 2014.
