Thief

The AMD Ryzen 9 7900X paired with the AMD Radeon RX 6750 XT delivers a broad range of performance in Thief, a 2014 stealth title. The measured data covers three resolutions and four settings presets, providing a clear picture of how this combination handles the game. Benchmark results indicate that the sweet spot for this pairing is the Medium preset, which offers a balanced experience across all tested resolutions, while High and Ultra settings remain viable at lower resolutions but become more demanding at 4K.

Settings Recommendations

The measured FPS rows show a clear progression across the four available presets: Low, Medium, High, and Ultra. At 1920x1080, the Low preset produces an average of 196 FPS, which is the highest frame rate recorded in the entire dataset. Medium at 1080p yields 148 FPS, High drops to 113 FPS, and Ultra settles at 108 FPS. These numbers indicate that at 1080p, even the most demanding preset maintains a frame rate well above typical display refresh rates, so users with 1080p monitors can comfortably select Ultra for maximum visual fidelity without sacrificing smoothness.

Moving to 2560x1440, the averages are 134 FPS for Low, 102 FPS for Medium, 78 FPS for High, and 74 FPS for Ultra. The gap between High and Ultra narrows considerably at this resolution, with only a 4 FPS difference, whereas the jump from Medium to High costs 24 FPS. This suggests that High offers diminishing returns over Medium, while Ultra provides little additional benefit over High. For 1440p users, Medium appears to be the most efficient choice, delivering 102 FPS while retaining a solid visual presentation.

At 3840x2160, the situation changes dramatically. Low produces 79 FPS, Medium drops to 60 FPS with a minimum of 51 and a maximum of 69, High falls to 46 FPS, and Ultra bottoms out at 43 FPS. The Medium preset at 4K is the only setting that maintains an average at or above 60 FPS, making it the recommended choice for 4K displays. High and Ultra at 4K fall below 50 FPS, which may introduce perceptible stutter in a stealth game where precise timing matters. The data shows that Medium at 4K offers a playable experience, while Low pushes frame rates higher but sacrifices visual quality.

Comparing presets across resolutions, the Medium preset provides the most consistent experience. At 1080p it delivers 148 FPS, at 1440p it drops to 102 FPS, and at 4K it holds at 60 FPS. This linear scaling makes Medium the best overall recommendation for users who want to maintain high frame rates without constantly adjusting settings. For users prioritizing visual quality over frame rate, Ultra at 1080p or 1440p remains viable, but the 4K Ultra result of 43 FPS suggests this preset is only suitable for those who accept lower responsiveness.

How This Combo Ranks

The combination of the AMD Ryzen 9 7900X and the AMD Radeon RX 6750 XT ranks 1528 out of 3720 tested combos in Thief. This places the pairing in the upper half of all tested configurations, specifically around the 59th percentile of the combo distribution. The rank reflects the overall performance of this specific CPU-GPU pairing in this particular game, accounting for both the processor’s ability to feed the graphics card and the GPU’s raw rendering throughput.

Given that the GPU sits at the 71st percentile among all GPUs and the CPU ranks at the 91st percentile among all CPUs, the combo rank of 1528 out of 3720 suggests that Thief is somewhat more sensitive to GPU performance than CPU performance. The CPU is a top-tier part by benchmark scores, but the GPU, while capable, is not at the same relative level. This imbalance likely contributes to the combo’s mid-tier ranking, as the GPU becomes the limiting factor in many scenarios.

The GPU’s nearest rivals in the overall benchmark database include the AMD Radeon R9 M395X, which scores 0.5% higher, the AMD FirePro W7100 at 0.6% higher, the AMD FirePro D700 at 0.7% higher, and the NVIDIA GeForce RTX 3080 Ti Mobile at 1.1% higher. These deltas are small, indicating that the RX 6750 XT sits in a tightly contested performance band. In Thief specifically, the combo rank of 1528 out of 3720 means that roughly 59% of tested combinations deliver higher average frame rates, while 41% deliver lower ones. This is a respectable position for a mid-range GPU paired with a high-end CPU.

The CPU’s nearest rivals show a similar clustering. The AMD EPYC 7313P scores 0.2% higher, the Intel Xeon 634 scores 0.6% higher, while the Intel Xeon Phi 7290 scores 0.3% lower and the Intel Core i7-14700F scores 0.6% lower. These tiny percentage differences reinforce that the Ryzen 9 7900X is near the top of CPU performance, but its contribution to Thief’s frame rates is capped by the GPU’s capabilities.

GPU Role

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with a Navi 22 chip manufactured on a 7 nm process. It features 12 GB of GDDR6 memory on a 192-bit bus, providing a memory bandwidth of 432.0 GB/s. The GPU’s base clock is 2150 MHz, the game clock is 2495 MHz, and the boost clock reaches 2600 MHz. Memory operates at 2250 MHz, translating to 18 Gbps effective. These specifications determine how the card handles Thief’s rendering workload.

In Thief, the GPU’s role is evident from the FPS scaling across resolutions. At 1080p, the card delivers between 108 and 196 FPS depending on the preset, which indicates it has ample headroom at lower pixel counts. The jump from Low to Ultra at 1080p costs 88 FPS, showing that the GPU’s shading units, texture mapping units, and raster operations are heavily utilized when visual effects increase. The card has 2560 shading units, 160 TMUs, and 64 ROPs, with a pixel rate of 166.4 GPixel/s and a texture rate of 416.0 GTexel/s. These resources process the game’s geometry and lighting effects.

At 1440p, the GPU’s limits begin to appear. Low settings yield 134 FPS, but Ultra drops to 74 FPS. The 60 FPS difference between Low and Ultra at this resolution highlights how the card’s 13.31 TFLOPS of FP32 compute power is taxed by higher quality shadows and reflections. The 12 GB VRAM buffer is sufficient for Thief at any resolution, as even 4K Ultra does not exceed the card’s memory capacity in the measured data.

The 4K results demonstrate the GPU’s boundary. Medium at 4K averages 60 FPS with a minimum of 51 and a maximum of 69, while High drops to 46 FPS and Ultra to 43 FPS. The card’s 432.0 GB/s bandwidth and 64 ROPs struggle to maintain high fill rates at 3840x2160 when complex effects are enabled. The GPU’s benchmark percentiles reflect this: it scores in the 71st percentile among all GPUs, with an average benchmark score of 26011. The nearest rival, the AMD Radeon R9 M395X, is 0.5% faster in synthetic benchmarks, but in Thief the RX 6750 XT’s performance is ultimately constrained by its mid-range positioning.

Measured FPS Breakdown

The measured data provides exact frame rates for every combination of resolution and preset. At 1920x1080, the Low preset averages 196 FPS, which is the highest score in the entire dataset. Medium at 1080p averages 148 FPS with a minimum of 126 and a maximum of 171. High at 1080p averages 113 FPS, and Ultra averages 108 FPS. The spread from Low to Ultra at 1080p is 88 FPS, indicating that the CPU and GPU can both handle the game comfortably at this resolution.

At 2560x1440, Low averages 134 FPS, Medium averages 102 FPS with a minimum of 87 and a maximum of 117, High averages 78 FPS, and Ultra averages 74 FPS. The difference between High and Ultra is only 4 FPS, while the difference between Medium and High is 24 FPS. This suggests that the Ultra preset at 1440p offers marginal improvements over High but at a significant performance cost relative to Medium. The minimum FPS for Medium at 1440p is 87, which remains above common 60 Hz refresh rates.

At 3840x2160, Low averages 79 FPS, Medium averages 60 FPS with a minimum of 51 and a maximum of 69, High averages 46 FPS, and Ultra averages 43 FPS. The Medium preset at 4K is the only one that maintains an average at 60 FPS, while High and Ultra fall below 50 FPS. The minimum FPS of 51 for Medium at 4K indicates occasional dips, but the overall experience remains playable. Low at 4K offers 79 FPS, which is smoother but requires significant visual compromises.

Comparing the same preset across resolutions, the scaling is consistent. Low goes from 196 FPS at 1080p to 134 FPS at 1440p to 79 FPS at 4K. Medium goes from 148 to 102 to 60. High goes from 113 to 78 to 46. Ultra goes from 108 to 74 to 43. The percentage drops from 1080p to 1440p are roughly 32% for Low, 31% for Medium, 31% for High, and 31% for Ultra. From 1440p to 4K, the drops are roughly 41% for Low, 41% for Medium, 41% for High, and 42% for Ultra. This uniform scaling indicates that the GPU is the primary factor limiting performance across all settings.

Resolution Scaling

The FPS drop from 1080p to 4K reveals which component is the bottleneck in this pairing. At 1080p Low, the system produces 196 FPS. At 1440p Low, it drops to 134 FPS, and at 4K Low, it falls to 79 FPS. The total reduction from 1080p to 4K is 117 FPS, or a 60% decrease. For Medium, the drop is from 148 to 60 FPS, a 59% decrease. High drops from 113 to 46, a 59% decrease, and Ultra drops from 108 to 43, a 60% decrease.

These percentage drops are nearly identical across all presets, which is a strong indicator that the GPU is the limiting component. If the CPU were the bottleneck, the frame rates at lower resolutions would plateau or show smaller drops as resolution increased. Instead, the consistent ~60% reduction from 1080p to 4K across all settings suggests that the RX 6750 XT’s rendering throughput is the constraint. The CPU, with 12 cores and 24 threads based on Zen 4 architecture, is more than capable of feeding the GPU at 1080p, as evidenced by the 196 FPS Low result.

The scaling from 1080p to 1440p shows a roughly 31% drop, while the scaling from 1440p to 4K shows a roughly 41% drop. This accelerating decline is typical of GPU-bound scenarios, where the pixel count increases quadratically. At 4K, the GPU’s 166.4 GPixel/s pixel rate is insufficient to maintain the same frame rates as lower resolutions, particularly when the game’s effects are enabled. The data shows that the Ryzen 9 7900X’s high single-thread and multi-thread performance does not compensate for the GPU’s limits in this title.

The fact that Ultra at 1080p (108 FPS) is faster than Low at 4K (79 FPS) further emphasizes the GPU’s role. The resolution increase from 1080p to 4K quadruples the pixel count, which directly impacts the GPU’s fill rate and memory bandwidth. The RX 6750 XT’s 432.0 GB/s bandwidth is sufficient for 1080p and 1440p, but at 4K it becomes a limiting factor, especially with higher quality textures and post-processing effects.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor from the Zen 4 architecture, codenamed Raphael, built on a 5 nm process at TSMC. It has a base clock of 4.70 GHz and a boost clock of 5.60 GHz, with 64 MB of shared L3 cache and 1 MB of L2 cache per core. The CPU’s memory support is DDR5 with dual-channel configuration, providing a memory bandwidth of 83.2 GB/s. These specifications make it a high-end desktop processor, ranking in the 91st percentile among all CPUs with an average benchmark score of 53288.

In Thief, the CPU’s role is less prominent than the GPU’s, as indicated by the resolution scaling analysis. However, the CPU’s performance still matters for achieving high frame rates at lower resolutions. At 1080p Low, the system reaches 196 FPS, which requires the CPU to process game logic and draw calls quickly. The Ryzen 9 7900X’s single-thread score of 2016.5 in Cinebench R23 and 2617 in Geekbench suggest it has excellent per-core performance, which is crucial for older games like Thief that may not scale well across many cores.

The CPU’s multi-threaded capabilities, evidenced by a Cinebench R23 multicore score of 29300 and a Passmark multithread score of 51406, provide headroom for background tasks but are not fully utilized by Thief, which was released in 2014. The game’s engine likely relies on a few threads for rendering and physics, so the 12-core, 24-thread configuration may be overkill. Yet the high boost clock of 5.60 GHz ensures that the few threads which are active run at very high speeds, minimizing CPU-related bottlenecks.

The CPU’s average benchmark score of 53288 places it close to the AMD EPYC 7313P, which is 0.2% faster, and the Intel Core i7-14700F, which is 0.6% slower. These rival comparisons show that the Ryzen 9 7900X is at the top of CPU performance, but in Thief, the measured FPS is limited by the GPU. The fact that 1080p Ultra (108 FPS) is only slightly higher than 1440p High (78 FPS) and 4K Medium (60 FPS) confirms that the CPU is not the primary constraint.

The CPU’s 83.2 GB/s memory bandwidth and DDR5 support ensure that data can be fed to the GPU without stalling. The L3 cache of 64 MB shared across all cores helps maintain low latency for frequently accessed game data. In Thief, this translates to consistent frame delivery, as evidenced by the minimum FPS values: 126 at 1080p Medium, 87 at 1440p Medium, and 51 at 4K Medium. These minimums are close to the averages, indicating minimal frame time spikes, which is partly attributable to the CPU’s strong single-thread performance.
