Thief

The Intel Core i5-11400F paired with the AMD Radeon RX 6650 XT delivers a playable but not maxed-out experience in Thief, with performance scaling that clearly identifies the GPU as the primary bottleneck at higher resolutions. The data shows a steep drop in frame rates as resolution increases, a pattern typical of a system where the graphics card is the limiting factor. At 1080p, the combo achieves a very fluid 148.8 FPS on Low settings, but this falls to 40.6 FPS at 4K on High settings, demonstrating that the RX 6650 XT is working progressively harder while the CPU has headroom to spare.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a textbook GPU-bound scenario. At 1920x1080 with Low settings, the system produces 148.8 FPS, which drops to 113.1 FPS at 2560x1440 and then to 63.7 FPS at 3840x2160. This represents a 57% reduction in performance from 1080p to 4K at Low settings. The pattern is consistent across all quality presets, with the Ultra preset showing the most dramatic fall: 86.8 FPS at 1080p, down to 58.8 FPS at 1440p, and finally 38.8 FPS at 4K.

The data indicates that the RX 6650 XT is the limiting component in this configuration. If the CPU were the bottleneck, we would expect to see smaller differences between resolutions, particularly at 1080p where the processor has more influence on frame pacing. Instead, the consistent 30-40% performance penalty when moving from 1440p to 4K across all settings confirms that pixel throughput is the constraint. The CPU, with its 6 cores and 12 threads, appears capable of feeding the GPU adequately even at lower resolutions where frame rates are highest.

How This Combo Ranks

Within the benchmark database, this specific combination of Intel Core i5-11400F and AMD Radeon RX 6650 XT ranks 1083 out of 1642 tested combos for Thief. This places the system in the lower-middle portion of the ranking, which is somewhat surprising given the individual component scores. The CPU ranks in the 75th percentile among all processors, and the GPU sits in the 72nd percentile among all graphics cards, yet their combined performance in this title does not break into the top half of tested systems.

The ranking suggests that Thief may not be particularly well-optimized for this hardware combination or that the game's engine favors different component pairings. The measured data shows the system is capable of high frame rates at 1080p, but the comboRankInGame of 1083 indicates that many other combinations achieve better results in this specific title. This is not a reflection of the components' general capability, but rather their specific interaction with Thief's rendering pipeline.

GPU Role

The AMD Radeon RX 6650 XT features 8 GB of GDDR6 memory on a 128-bit bus, providing 280.3 GB/s of bandwidth. The GPU runs at a base clock of 2055 MHz with a boost clock of 2635 MHz, and it is built on the RDNA 2.0 architecture using a 7 nm process. These specifications translate to a PassMark G3D score of 17166, which places the GPU in the 72nd percentile of all graphics cards.

In Thief, the GPU's memory configuration appears sufficient for the game's demands, as frame rates remain playable even at 4K with High settings (40.6 FPS). The 8 GB VRAM is not shown to be a limiting factor in the measured results, as the performance drop from Medium to Ultra at 4K is only 13.5 FPS (from 52.3 to 38.8). The GPU's boost clock of 2635 MHz is likely a key factor in maintaining competitive frame rates at 1440p, where the system achieves 65.8 FPS on High settings.

Measured FPS Breakdown

At 1920x1080, the system delivers its best performance across all settings. Low settings produce 148.8 FPS, Medium achieves 121.1 FPS, High reaches 93.2 FPS, and Ultra dips to 86.8 FPS. These numbers indicate that 1080p gaming is smooth even at the highest quality preset, with no settings combination falling below the 60 FPS threshold.

Moving to 2560x1440, the performance drops become more pronounced. Low settings yield 113.1 FPS, Medium manages 81.9 FPS, High hits 65.8 FPS, and Ultra falls to 58.8 FPS. The 1440p results show that High settings are still playable, but Ultra settings begin to strain the GPU, dropping just below 60 FPS.

At 3840x2160, the system struggles to maintain high frame rates. Low settings produce 63.7 FPS, Medium achieves 52.3 FPS, High drops to 40.6 FPS, and Ultra falls to 38.8 FPS. The 4K results demonstrate that this combination is only viable at Low settings for a consistently smooth experience, with Medium settings being marginal and High/Ultra requiring compromises.

FAQ

*Q: What is the best resolution for this combo in Thief?*

A: The data shows 1920x1080 is the sweet spot, with all settings delivering above 86 FPS. At 2560x1440, only Low and Medium settings stay above 80 FPS, while 4K requires Low settings to maintain 60 FPS.

Q: How does the RX 6650 XT's VRAM affect performance?

A: The 8 GB GDDR6 memory with 280.3 GB/s bandwidth does not appear to be a bottleneck in Thief. The performance difference between Medium and Ultra at 4K is 13.5 FPS, suggesting the game fits within the memory allocation.

Q: Is the CPU holding back the GPU in this game?

A: No. The 6-core, 12-thread i5-11400F with a boost clock of 4.40 GHz appears sufficient. The consistent frame rate drops across resolutions indicate the GPU is the limiting factor, not the processor.

*Q: Can this system handle 4K gaming in Thief?*

A: Only at Low settings, where it achieves 63.7 FPS. Medium settings drop to 52.3 FPS, and High/Ultra fall below 41 FPS, which may not provide a smooth experience.

Q: What is the performance difference between 1080p and 4K on High settings?

A: The system produces 93.2 FPS at 1080p and 40.6 FPS at 4K on High settings, representing a 56% reduction in frame rate when moving to 4K.

Q: How does this combo rank compared to other tested systems?

A: It ranks 1083 out of 1642 tested combos for Thief, placing it in the lower-middle range despite the individual components having above-average benchmark scores.

CPU Role

The Intel Core i5-11400F contributes to the system's overall capability with its 6 cores and 12 threads, operating at a base clock of 2.60 GHz and boosting to 4.40 GHz. The processor achieves a Cinebench R23 multicore score of 14372 and a single-core score of 2029, with a PassMark multithread score of 16908. The CPU's performance places it in the 75th percentile of all processors, with its nearest rivals being the AMD Ryzen 7 5700U and Intel Core i7-1260P, both within 0.2% of its average score.

In Thief, the CPU's role appears secondary to the GPU. The measured frame rates at 1080p Low settings reach 148.8 FPS, which would require the processor to maintain high frame pacing. The i5-11400F's 12 MB of shared L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth provide adequate data throughput for the game's stealth-based gameplay, which typically involves complex AI and physics calculations. The 14 nm process node and 65 W TDP suggest the CPU operates within reasonable thermal limits, though these factors are not directly reflected in the game's performance metrics.

Settings Recommendations

For the best balance of visual quality and performance, the data supports using High settings at 1920x1080, where the system achieves 93.2 FPS. This provides a significant improvement over Medium (121.1 FPS) in visual fidelity while maintaining frame rates well above the 60 FPS threshold. At 2560x1440, High settings at 65.8 FPS offer the best experience for users with higher-resolution monitors, though Medium settings at 81.9 FPS provide a larger safety margin for demanding scenes.

For 4K gaming, Low settings at 63.7 FPS are the only viable option for smooth gameplay. Medium settings at 52.3 FPS might be acceptable for slower-paced stealth gameplay, but the 38.8 FPS at Ultra settings will likely result in noticeable stuttering. The measured data suggests that Ultra settings provide diminishing returns in Thief, with only a 6.4 FPS difference between High and Ultra at 1080p, making High the most efficient quality setting across all resolutions.
