Thief

The AMD Ryzen 5 2600 and AMD Radeon RX 6800 XT pairing in Thief presents a classic generational mismatch: a 2018 Zen+ processor paired with a 2020 RDNA 2 flagship. The measured frames reveal a system where the GPU often has headroom, but the CPU's architecture and memory bandwidth cap the ceiling. This analysis breaks down the data from the benchmark database to show exactly where the bottleneck lives and how the settings sliders change the experience.

FAQ

*Q: What is the overall rank of this CPU and GPU combo in Thief?*

A: The combo ranks 1005 out of 1642 tested combinations. This places it in the lower-middle tier of the database, indicating that while the RX 6800 XT is a strong GPU, the Ryzen 5 2600 holds the pairing back from top-tier performance in this title.

Q: How does the Ryzen 5 2600 compare to its closest rivals in synthetic benchmarks?

A: The CPU's average benchmark score is 19616, which puts it at the 77th percentile of all CPUs. Its nearest rival, the Intel Core i5-1345U, scores 19691, a delta of -0.4%, meaning the Ryzen 5 2600 is essentially tied with that mobile chip. It is 0.7% faster than the Intel Core i7-10700F (19485), showing that its multi-threaded capability is still competitive with newer mainstream parts.

Q: How does the RX 6800 XT's synthetic performance compare to its nearest rivals?

A: The GPU's average benchmark score is 49982, placing it at the 87th percentile of all GPUs. It trails the NVIDIA RTX A1000 by 1.7% (50826) but is 2.6% ahead of the NVIDIA GeForce RTX 4070 Ti SUPER (48704). This suggests the GPU is a high-end performer, well above average, yet the in-game FPS don't always reflect that raw power.

Q: What is the best preset to use at 1080p for the highest average frame rate?

A: The Low preset at 1920x1080 yields the highest average of 108.9 FPS. However, moving to Medium only drops the average to 101.7 FPS, which is a small penalty for a significant visual upgrade. The data suggests Medium is the sweet spot for smoothness and quality at this resolution.

Q: Is the system more CPU-bound or GPU-bound at 4K with Ultra settings?

A: At 3840x2160 with Ultra settings, the average FPS is 55.8. This is a substantial drop from the 1080p Ultra result of 88.9 FPS. The scaling indicates that at 4K, the GPU is the primary limiting factor, as the increased resolution demands more pixel-pushing power than the CPU's frame generation limit.

Q: Does the Ryzen 5 2600's memory bandwidth affect the RX 6800 XT's performance?

A: The CPU supports DDR4 memory with 46.9 GB/s of bandwidth. While the GPU has its own 512.0 GB/s of VRAM bandwidth, the CPU's data feed rate can bottleneck the GPU's request queue. The measured FPS, especially at lower resolutions, suggest this is a factor, as the GPU is not fully saturated.

CPU Role

The AMD Ryzen 5 2600 is a 6-core, 12-thread processor based on the Zen+ architecture, built on a 12 nm process. Its base clock is 3.40 GHz, boosting up to 3.90 GHz. The CPU has a 16 MB shared L3 cache and a 65W TDP. In Thief, a title from 2014, the game's engine is likely sensitive to single-core performance and memory latency. The CPU's Cinebench R23 single-core score of 1579 is modest by modern standards, which explains why the frame rates at 1080p, where the CPU is more likely to be the bottleneck, don't reach the GPU's potential.

The benchmark results show the Ryzen 5 2600 has an average benchmark score of 19616, placing it at the 77th percentile. Its nearest rival, the Intel Core i5-1345U, is 0.4% faster, but the Ryzen 5 2600 is 0.6% faster than the AMD Ryzen 5 7530U. This suggests that while the CPU is aging, its 12 threads still provide a solid foundation for modern games. However, the data implies that in Thief, the CPU's relatively low single-threaded throughput (Passmark single-thread score of 2239) prevents it from delivering the high frame rates that the RX 6800 XT is capable of at lower resolutions. The gap between the 1080p Low (108.9 FPS) and the 4K Low (84.1 FPS) is only 24.8 FPS, which is a smaller drop than expected for a GPU-bound scenario, hinting that the CPU is limiting the maximum frame output even at 1080p.

GPU Role

The AMD Radeon RX 6800 XT is a formidable GPU, featuring the Navi 21 chip with RDNA 2.0 architecture on a 7 nm process. It has 4608 shading units, 288 TMUs, and 128 ROPs. The GPU's base clock is 1825 MHz, with a boost clock of 2250 MHz. It comes equipped with 16 GB of GDDR6 memory on a 256-bit bus, providing 512.0 GB/s of bandwidth. This is a high-end card, as evidenced by its 87th percentile ranking among all GPUs and its average benchmark score of 49982.

In Thief, the GPU's raw power is evident in the scaling from 1080p to 1440p. At High settings, the frame rate drops from 91.6 FPS at 1080p to 78.2 FPS at 1440p. This is a 14.6% performance hit, which is a moderate scaling curve. The RX 6800 XT is clearly capable of handling the game's textures and effects, as the 16 GB VRAM buffer is more than sufficient for a 2014 title. The data shows that the GPU is not the primary bottleneck until the resolution reaches 4K. At 4K Ultra, the average FPS is 55.8, which is a playable frame rate, but the GPU is clearly working harder. The difference between the 4K Low (84.1 FPS) and 4K Ultra (55.8 FPS) is 28.3 FPS, showing that the GPU's shading units and ROPs are being taxed by the higher settings.

Settings Recommendations

The measured data across all resolutions suggests that the Medium preset offers the best balance between visual fidelity and performance for this specific combo. At 1080p, Medium produces an average of 101.7 FPS, which is a 7.2 FPS drop from Low but a 12.8 FPS increase over High. The jump to Ultra only costs 12.8 FPS compared to Medium, but the difference between Medium and High is smaller, indicating a sweet spot.

At 1440p, the Medium preset delivers 87.5 FPS, which is still comfortably above 60 FPS. High settings at this resolution produce 78.2 FPS, which is also smooth, but Medium provides a better margin for dips. The data indicates that the CPU's limitations are less pronounced at 1440p, as the GPU starts to take on more of the load. For 4K, the Medium preset (71.8 FPS) is the only way to maintain a high refresh rate experience. High settings (52.4 FPS) and Ultra (55.8 FPS) dip into the 50 FPS range, which is acceptable for a slower-paced stealth game but not ideal.

The recommendation is to use Medium settings for the best overall experience. It provides a significant visual upgrade over Low while maintaining frame rates that are close to the CPU's maximum output at 1080p and 1440p.

How This Combo Ranks

The combo rank of 1005 out of 1642 (approximately the 61st percentile) is a telling statistic. It places this pairing below the median of all tested combos, which is surprising given the GPU's high percentile ranking. This discrepancy reinforces the idea that the Ryzen 5 2600 is the limiting factor. The RX 6800 XT is capable of competing with GPUs that score significantly higher, but the CPU's performance in Thief's engine prevents the combo from achieving a higher rank.

The data suggests that pairing the RX 6800 XT with a newer, higher-clocked CPU would likely move this combo into the top quartile. The GPU's synthetic benchmark scores (87th percentile) are far superior to the CPU's (77th percentile), and the combo's rank is dragged down by the CPU's inability to feed the GPU frames fast enough. This is a classic case of a bottleneck, where the overall system performance is constrained by the weakest link.

Measured FPS Breakdown

The following is the complete measured FPS data for Thief with this hardware.

At 1920x1080:

• Low: 108.9 FPS
• Medium: 101.7 FPS
• High: 91.6 FPS
• Ultra: 88.9 FPS

At 2560x1440:

• Low: 98.0 FPS
• Medium: 87.5 FPS
• High: 78.2 FPS
• Ultra: 79.6 FPS

At 3840x2160:

• Low: 84.1 FPS
• Medium: 71.8 FPS
• High: 52.4 FPS
• Ultra: 55.8 FPS

At 1080p, the frame rates are tightly clustered, with only a 20 FPS difference between Low and Ultra. This suggests the CPU is the primary limiter, as the GPU has ample headroom. At 1440p, the spread widens slightly, but the Ultra setting (79.6 FPS) is actually faster than High (78.2 FPS), which is an anomaly. This could be due to driver-level optimizations or a specific scene variance. At 4K, the GPU becomes the bottleneck, and the frame rates drop sharply, with High and Ultra both falling below 60 FPS.

Resolution Scaling

The performance scaling from 1080p to 4K provides insight into the system's bottleneck. At Low settings, the average FPS drops from 108.9 at 1080p to 84.1 at 4K, a 22.8% decrease. At Medium, the drop is from 101.7 to 71.8, a 29.4% decrease. At High, the drop is from 91.6 to 52.4, a 42.8% decrease. Finally, at Ultra, the drop is from 88.9 to 55.8, a 37.2% decrease.

The trend is clear: as settings increase, the resolution scaling penalty becomes more severe. This indicates that the GPU is the limiting component at higher settings and resolutions. However, the relatively small drop at Low settings (22.8%) suggests that even at 4K Low, the CPU is still able to keep up with the GPU's frame generation. The larger drop at High settings (42.8%) shows that the GPU's shading units and memory bandwidth are being saturated by the combination of high resolution and detailed effects. The data implies that the RX 6800 XT is a capable 4K card for this game, but only at Medium settings or below. The CPU's performance at lower resolutions is the main factor preventing this combo from achieving higher frame rates, as the GPU is not fully utilized until the resolution increases significantly.
