Thief

The AMD Ryzen 5 5600GT paired with the NVIDIA GeForce RTX 4080 SUPER delivers a striking performance profile in Thief, characterized by a significant CPU bottleneck at lower resolutions and a shift toward GPU dominance at 4K. The measured frame rates reveal a system that is capable of high refresh rate gameplay at 1080p and 1440p, yet still maintains playable, though markedly lower, performance at 4K Ultra settings. This analysis breaks down the scaling behavior, component roles, and optimal settings based solely on the measured data.

Resolution Scaling

The frame rate progression from 1080p to 4K clearly illustrates where the bottleneck lies within this configuration. At 1920x1080 with High settings, the average FPS is 134. Moving to 2560x1440 High, the average drops to 119 FPS, a reduction of approximately 11%. Further scaling to 3840x2160 High yields an average of 75 FPS, representing a steep 37% decline from the 1440p result. This pattern indicates that at 1080p, the system is heavily constrained by the CPU, as the GPU has ample headroom to render frames quickly, but the processor cannot feed it data fast enough.

The behavior becomes more telling when examining the Low settings preset. At 1080p Low, the average FPS is 164, which is only 18% higher than the 1080p High result of 134 FPS. This modest gain suggests that even at Low settings, the CPU is the limiting factor, preventing the GPU from fully flexing its capabilities. At 1440p Low, the average is 145 FPS, a drop of 12% from 1080p Low. The jump to 4K Low produces an average of 121 FPS, a 17% decrease from 1440p Low. This scaling shows that as resolution increases, the GPU begins to take on more of the workload, but the CPU bottleneck remains present even at 4K Low.

The most telling data point is the difference between Low and Ultra presets at each resolution. At 1080p, the spread between Low (164 FPS) and Ultra (132 FPS) is only 32 FPS, or about 20%. At 1440p, the spread narrows to 28 FPS (145 vs 117). At 4K, the spread expands to 49 FPS (121 vs 72). This widening gap at higher resolutions confirms that the GPU becomes the primary bottleneck at 4K, where the increased pixel count demands more rendering power. The RTX 4080 SUPER's 16 GB of GDDR6X memory and 736.3 GB/s bandwidth are sufficient to handle the data load, but the sheer pixel throughput required at 3840x2160 overwhelms the GPU, causing the frame rate to plummet.

The evidence strongly suggests that this game, released in 2014, is not optimized for modern multi-core processors. The Ryzen 5 5600GT, with its 6 cores and 12 threads, has a high single-thread score of 913 in 3DMark, but the game likely relies heavily on one or two threads. This is corroborated by the minimal FPS gains when lowering settings from High to Low at 1080p. The system is effectively "CPU-bound" at 1080p and "GPU-bound" at 4K, with 1440p representing a transitional zone where both components contribute to the final frame rate.

CPU Role

The AMD Ryzen 5 5600GT is a 7nm Zen 3 part with a base clock of 3.60 GHz and a boost clock of 4.60 GHz. Its benchmark scores indicate solid single-thread performance, with a Cinebench R23 single-core score of 2438 and a Geekbench single-core score of 1843. In multi-threaded workloads, it achieves a Cinebench R23 multi-core score of 17272 and a Geekbench multi-core score of 7986. These numbers place it in the 74th percentile of all CPUs, with an average benchmark score of 20733.

In Thief, the CPU's role is paramount at lower resolutions. The measured FPS data shows that at 1080p, the average FPS across all settings (Low: 164, Medium: 148, High: 134, Ultra: 132) is relatively close, with a maximum variance of only 32 FPS. This indicates that the CPU is the limiting factor, as reducing graphical load does not proportionally increase frame rates. The game's engine, likely designed for earlier hardware, does not effectively utilize the 12 threads available, leaving many cores idle.

Comparing the 5600GT to its nearest rivals in the CPU benchmark database, it performs nearly identically to the Intel Core i5-12490F, with a deltaPct of -0.3%. This means the 5600GT is essentially on par with that Intel chip in general processing tasks. The AMD EPYC 7J13, a server-class processor, shows a deltaPct of -0.5%, indicating the 5600GT is slightly faster in the average benchmark score. However, these general benchmarks do not translate directly to gaming performance, especially in a title like Thief that is likely single-thread bound.

The CPU's 16 MB of L3 cache and 51.2 GB/s memory bandwidth are sufficient for this game, but they do not overcome the fundamental limitation of the game's engine. The boost clock of 4.60 GHz is relatively high, which should help in single-threaded scenarios, but the measured FPS at 1080p suggests that even this is not enough to push frame rates beyond the 164 FPS observed at Low settings. The data indicates that the CPU is the primary bottleneck at 1080p and 1440p, and its performance directly caps the maximum achievable frame rate.

How This Combo Ranks

In the database of tested hardware combinations for Thief, this pairing of the AMD Ryzen 5 5600GT and NVIDIA GeForce RTX 4080 SUPER achieves a rank of 692 out of 3720 total combos. This places the system in the 81st percentile, meaning it outperforms roughly 81% of all tested configurations. Given the game's age and its apparent single-threaded nature, this ranking is respectable but not exceptional, as the CPU bottleneck prevents the top-tier GPU from fully asserting dominance.

The ranking suggests that while the RTX 4080 SUPER is a high-end card (86th percentile among all GPUs), its potential is not fully realized in Thief due to the 5600GT's performance ceiling. The CPU's 74th percentile ranking among all processors indicates it is a mid-to-upper tier part, but it is not a top-tier gaming CPU. The combination's overall rank of 692 reflects this mismatch, where a more powerful CPU would likely push this combo higher in the rankings, especially at 1080p where the CPU is the limiting factor.

The data implies that for owners of this combo, the experience is highly playable, with even the lowest 4K Ultra average of 72 FPS being above the 60 FPS threshold. However, the system does not reach the extreme frame rates that the RTX 4080 SUPER might achieve with a higher-end CPU, such as those in the top 10% of the CPU benchmark charts. The rank of 692 confirms the balanced, if not perfectly optimized, nature of this pairing for this specific title.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the user's resolution and refresh rate goals. At 1920x1080, the High preset (134 FPS) offers a significant visual upgrade over Low (164 FPS) with only a 30 FPS penalty. The Medium preset (148 FPS) provides a middle ground, but High is recommended for the best balance of visual quality and performance, as the frame rate remains well above 120 FPS.

At 2560x1440, the High preset (119 FPS) is the recommended choice for most users, as it delivers a smooth experience above 100 FPS. The Ultra preset (117 FPS) is nearly identical in performance, with only a 2 FPS difference, making it a viable option for those who want maximum visual fidelity without a significant frame rate cost. The Medium preset (131 FPS) offers a slight boost, but the visual difference between Medium and High is likely worth the small FPS trade-off.

At 3840x2160, the situation changes. The High preset (75 FPS) is the sweet spot, providing a playable experience above 60 FPS. The Ultra preset (72 FPS) is also playable, but the 3 FPS difference does not justify the potential stability concerns. The Medium preset (99 FPS) is the best choice for 4K gamers who prioritize frame rate, as it offers a substantial 24 FPS improvement over High while still maintaining decent visual quality. The Low preset (121 FPS) is recommended only for competitive play or if the user has a 120 Hz 4K monitor, as it sacrifices too much visual fidelity for the 22 FPS gain over Medium.

For the best overall experience, the Medium preset at 4K (99 FPS) or the High preset at 1440p (119 FPS) are the strongest recommendations, depending on the user's display capabilities. The data shows that the Ultra preset offers minimal gains over High in terms of FPS, making it a poor value in performance terms.

Measured FPS Breakdown

The full measured FPS data for this combo is as follows:

1920x1080:

• Low: 164 FPS average
• Medium: 148 FPS average, with a minimum of 126 FPS and maximum of 171 FPS
• High: 134 FPS average
• Ultra: 132 FPS average

2560x1440:

• Low: 145 FPS average
• Medium: 131 FPS average, with a minimum of 111 FPS and maximum of 151 FPS

• Low: 121 FPS average
• Medium: 99 FPS average, with a minimum of 84 FPS and maximum of 114 FPS
• High: 75 FPS average
• Ultra: 72 FPS average

The Medium preset at each resolution is the only one with recorded minimum and maximum FPS values. At 1080p, the minimum of 126 FPS indicates that the frame rate never drops below a highly playable threshold. At 1440p, the minimum of 111 FPS is still smooth, but the 40 FPS spread between minimum and maximum (111 to 151) suggests some frame time inconsistency. At 4K, the minimum of 84 FPS on Medium is concerning, as it approaches the 60 FPS threshold, but the average of 99 FPS confirms that the experience is generally smooth.

The Ultra preset consistently produces the lowest average FPS at every resolution, with 132 at 1080p, 117 at 1440p, and 72 at 4K. The difference between High and Ultra is minimal across all resolutions, with only 2-3 FPS separating them, making Ultra a questionable choice for this game. The Low preset provides the highest frame rates but at a significant visual cost, as evidenced by the 43 FPS difference between Low and Ultra at 4K.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER is a high-end graphics card built on the Ada Lovelace architecture, featuring a boost clock of 2550 MHz and 16 GB of GDDR6X memory on a 256-bit bus, delivering 736.3 GB/s of bandwidth. Its raw compute power is substantial, with 52.22 TFLOPS of FP32 performance and 80 RT cores for ray tracing. In the GPU benchmark database, it achieves a Passmark G3D score of 34245 and a 3DMark Steel Nomad DX12 score of 6600, placing it in the 86th percentile of all GPUs.

In Thief, the GPU's role becomes increasingly important as resolution rises. At 1080p, the GPU is underutilized due to the CPU bottleneck, as evidenced by the only 32 FPS difference between Low and Ultra settings. However, at 4K, the GPU's workload increases dramatically, and the 49 FPS difference between Low (121 FPS) and Ultra (72 FPS) demonstrates its dominant role. The RTX 4080 SUPER's memory capacity of 16 GB is more than sufficient for this game, even at 4K Ultra, and the 736.3 GB/s bandwidth ensures that texture streaming is not a bottleneck.

The GPU's nearest rival, the RTX 4080, has a nearly identical average benchmark score (54247 vs 54209, a deltaPct of -0.1%), indicating that the SUPER variant offers no meaningful performance advantage in general benchmarks. In Thief, this similarity likely translates to near-identical frame rates, meaning the GPU's performance is well-established. The card's 5nm process node and 45,900 million transistors provide ample headroom for this older title, but the game's engine does not appear to utilize the GPU's newer features, such as ray tracing or DLSS, which are not mentioned in the measured data.

The GPU's measured performance in Thief is characterized by its ability to maintain high frame rates at 1440p and below, with the bottleneck shifting to the CPU. At 4K, the card still delivers playable frame rates above 60 FPS even at Ultra settings, showcasing its raw power. However, the 72 FPS at 4K Ultra is a far cry from the 164 FPS possible at 1080p Low, highlighting the significant impact of resolution on this GPU's performance in this specific title.
