Thief

The AMD Ryzen 5 5600 paired with the AMD Radeon RX 6650 XT presents a specific performance footprint for the 2014 stealth game Thief. The measured data for this combination, taken across three resolutions and four quality presets, reveals a GPU-bound system that delivers smooth frame rates at 1080p and 1440p, but requires aggressive settings tuning at 4K. This analysis interprets those results, the underlying hardware capabilities, and the practical implications for players, using only the numbers gathered in the benchmark database.

Resolution Scaling

The measured FPS values show a clear and consistent pattern of scaling as resolution increases. At 1920x1080 with the High preset, the average FPS is 93. When the resolution rises to 2560x1440, the average falls to 64, a drop of 29 frames, which corresponds to roughly a 31.2% reduction. Moving to 3840x2160, the average plummets to 38, another 40.6% reduction from the 1440p result. This pattern—approximately a one-third loss from 1080p to 1440p and another one-third loss from 1440p to 4K—is consistent with pixel-count scaling. The total pixel count from 1080p to 1440p increases by a factor of 1.78, and from 1440p to 4K by 2.25, yet the framerate losses are lower than the pixel increases, indicating that the frame rate is not strictly linear with the pixel count.

Looking at the other presets, the same narrative holds. With Low quality, the average FPS moves from 160 at 1080p to 111 at 1440p (a 30.6% drop) and then to 65 at 4K (a 41.4% drop). For Medium settings, the average sequence is 123, 84, and 49, representing losses of 31.7% and a 41.7%% respectively. Ultra produces values of 39, 61, and 38, with a 31.0% drop from 1080p to 1440p and a 37.7% drop from 1440p to 4K. The average FPS differences between the two transitions are remarkably close across all four presets, which strongly suggests that the GPU is the primary determinant the FPS. If the CPU were the bottleneck, we would expect to see a diminishing or flat curve as resolution increases, as the CPU workload would skew a more constant portion of the frame time. Instead, the data () shows a consistent linearization fall with rising pixel count, so the RX 6650 XT is the thread that pulls the frame production in Thief. The CPU, with its 6 cores and 12 threads, has enough headroom to let the GPU operate at these scaling rates.

GPU Role

The Radeon RX 6650 XT is an RDNA 2.0 architecture card (Navi 23) with a base clock of 2055 MHz, a game clock of 2410 MHz, and a boost clock of 2635 MHz. Its memory subsystem is 8 GB GDDR6 on a 128-bit bus, achieving 280.3 GB/s of bandwidth. These clocks translate to a physical pixel throughput of 168.6 GPixel/s and a texture fill rate of 337.3 GTexel/s, with a raw FP32 compute of 10.79 TFLOPS. The numbers align with the observed 1080p performance: at High settings, the average 93 FPS requires a hex fill rate of 93 around 2.07 million pixels per frame (420p), which is roughly 192e6 pixels per second, well below the 168.6 GPixel/s limit. The card is not stretched at 1080p; it is only moving about 5% of its theoretical pixel throughput at that demand. However, that fraction rises at higher resolutions. At 4K Medium, the card handles 49 FPS at 3850x2160, which comes to about 49 8.29 million = 406 million pixels per second, still far under the 169 GPixel/s, so the limiting factor is not the ROPs but rather the memory bandwidth constraints. The 8 GB VRAM is sufficient since Thief's textures do not require more than 8GB, even at 4K, given the game's age. The measured data confirms that the GPU is the ultimate limiting component in this pairing.

The GPU’s benchmark scores align with this role. Its passmark G3D score is 17166, its DirectX 11 score is 169, and its DirectX 12 score is bigger 62. The Radeon's performance is essentially on par with the professional products: the nearest rival, the NVIDIA Tesla K40m, has an average score of 19889, with a deltaPct of -0.6%, while the AMD FirePro D300 comes with 102 higher, and the AMD FirePro W7000 is 0.7% faster. These professional cards are not gaming-focused but show that the RX 6650 XT’s compute capability is mid-tier when stacked against the gaming landscape. Its percentile vs all GPUs is 65, meaning only around a third of GPUs are slower, but it is not a high-end solution.

How This Combo Ranks

The combination to be tested ranks 2412 out of 3720 currently tracked combinations in Thief. This puts it in the 64.8th percentile, meaning that there is a 2411 (3650) other combos outperform it, and only 1308 combos are below it. The ranking reflects the overall matchup of the CPU and GPU in this specific game. The CPU, the Ryzen 5 5600, is a 6-core, 12-thread processor with a base of 3.50 GHz and boost of 4.40 GHz, and its overall benchmark average is 20468. In the overall CPU list, it sits in the 74th percentile. The GPU, the RX 6650 XT, has an average bench score of 19765, putting it in the 65th percentile. Yet the combo lands in the 64.8 percentile of the game's list, which is roughly the same as the GPU’s percentile. This suggests that the game performance is dominated by the GPU’s strength; the CPU, while more capable (higher percentile), is not the deciding factor. The CPU’s nearest rivals—the Intel Core Ultra 7 258V (avg 20454, delta 0.1%), the AMD Ryzen 5 8500G (delta 0.2%)—are extremely close in compute, showing the Ryzen 5 5600 is competitive with more recent chips. The GPU also has similar near-rival scoring, within 1% of a Tesla K40m and Quadro K5200. Therefore, the combo's in-game rank is exactly what you would predict: the GPU, being the weaker relative participant, tugs the overall specification down accordingly.

Measured FPS Breakdown

The benchmark data provides the following average FPS rows:

• 1920x1080 Low: 160, Medium: 123 (min 104, max 141), High: 93, Ultra: 89
• 2560x1440 Low: 111, Medium: 84 (min 72, max 97), High: 64, Ultra: 61
• 3840x2160 Low: 65, Medium: 49 (min 42, max 57), High: 38, Ultra: 36

At 1080p, even the highest preset, Ultra, returns 89 FPS, far above the 60 FPS baseline. The difference between Medium and High is a drop from 123 to 93 (a 24.4% cut), and High to Ultra only drops from 93 to 89, a modest 4.3% reduction. This shows that the final step from High to Ultra is cost-saving and barely touches the frame yield, so players have little reason to step down from Ultra except for very minor improvements.

At 1440p, Medium yields a comfortable 84 average, with a minimum of 72, meaning no dips below 60. High averages 64, which is stable for a typical 60 Hz display, while Ultra barely clears 60 at 61. The jump from Ultra to Medium raises the average by 38% (from 61 to 84). For users who prioritize consistent, high refresh, Medium is the balancing point.

Native 4K is where the card struggles. Low is the only preset that breaks the 60 FPS barrier, at 65 FPS. Medium averages 49, with a minimum of 42, and getting worse at 38 (High) and 36 (Ultra). These 4K numbers (below 60) mean that playing at 4K is only feasible with reduced quality. The game is from 2014, so its newness makes 4K viable; the 8 GB VRAM is not constrained at these settings.

Settings Recommendations

After reviewing the measured rows, the recommended preset depends on target resolution and framerate. For a 1920x1080 display, the data supports Ultra: with an average of 89 FPS, it offers the highest visual fidelity while remaining well above 60. If a high refresh rate display is in use, the GPU can achieve 160 FPS at Low, which is why some might choose Low, but that sacrifices visual richness.

At 2560x1440, the Ultra preset is usable as it sits at 64 FPS, but just barely. For a smoother experience and headroom, Medium ranks best with 84 FPS and a minimum of 72. High at 64 is a happy middle, but there is no minimum FPS measurement; the risk of a momentarily sub-60 drop exists, while the Medium has a demonstrated 72 FPS floor.

For 3840x2160, the only setting that reaches the 60 FPS target is Low at 65. Medium and above are all below 60, and the minimum set for Medium is 42, which indicates significant frame time variability. A player wanting a 60 FPS experience at 4K must use Low; any other preset will cause ideated stutter or motion pacing. The data is clear that this combination is at the edge of 4K capability for this title.

CPU Role

The Ryzen 5 5600's role in this system is undeniably that of a strong partner for the GPU, never becoming the primary limiter. The processor, built on the Zen 3 architecture (Vermeer) via a 7 nm process, has 6 cores and 12 threads with a base clock of 3.50 GHz and a boost of 4.40 GHz. Its TDP is 65 W, which is modest for its class. The CPU's benchmark results, such as a Cinebench R23 multi-core score of 18309 and a single-core of 2584, indicate that its brute multi-core performance is good enough for a 2014 game that typically uses up to 4 or 6 threads. The Passmark single-thread score of 3256 further reinforces its strong single-core arithmetic, which is what matters most for legacy titles like Thief.

The relationship between CPU and GPU is revealed in the resolution graphs. At 1080p Low, the combination produces 160 FPS, so the CPU must deliver at least that many visual frames per second; given that the Ryzen 5 5600 has a single-thread score of 2584 in Cinebench R23, this is well within its capability. As we raise the resolution to 1440p and 4K, the frame rate is cut, but the CPU's workload stays roughly the same, which is why the FPS drops align with pixel count. The CPU’s 3DMark max thread score of 5659 is not strained, further supporting the notion that the game engine is GPU-intense. Consequently, the 74th percentile CPU may be overkill for this title, but it provides enough overhead to ensure no CPU-based stutter.

The 5600’s overall benchmark score of 20468 places it alongside the Intel Core Ultra 7 258V (20458) and the AMD Ryzen 5 8500G (204858), but for Thief, the pacing is set by the GPU. A higher-end CPU might gain a few FPS at 1080p where the game is not completely GPU-limited, but the data shows that only at 160 FPS does the Low preset test the GPU's elasticity, while the higher resolutions are far from the CPU’s limit. Thus, the AMD Ryzen 5 5600 is a solid balance–it does not inhibit the RX 6650 XT, and pushes frame rates to the GPU's built-in ceiling. The combination's final rank, a 2412th place, reflects the GPU’s constraint and the game's inherent demand
