Thief

The Intel Core Ultra 9 290K Plus paired with the AMD Radeon RX 6800 XT delivers a highly capable Thief experience, but the data reveals a clear performance hierarchy that shifts depending on resolution and settings. At 1080p, this combo is overwhelmingly CPU-bound, producing frame rates that exceed 200 FPS on lower presets, while at 4K, the GPU becomes the definitive limiter, with frame rates dropping below the 60 FPS threshold on the highest settings. The benchmark results show a system that is exceptionally strong for high-refresh-rate 1440p gaming, yet struggles to maintain smooth 4K Ultra performance, making the choice of settings and resolution critical for the intended display.

Resolution Scaling

The measured FPS data shows a dramatic scaling curve from 1080p to 4K, with the frame rate dropping by more than half at every settings tier. At Low settings, the average frame rate falls from 236 FPS at 1920x1080 to 162 FPS at 2560x1440, a reduction of 74 FPS, and then further down to 95 FPS at 3840x2160, a 141 FPS total drop from the baseline. This steep decline indicates that while the CPU is capable of pushing extremely high frame counts at lower resolutions, the GPU quickly becomes the bottleneck as pixel count increases.

At Medium settings, the pattern continues with averages of 179 FPS, 123 FPS, and 72 FPS across 1080p, 1440p, and 4K respectively. The delta between 1080p and 1440p is 56 FPS, while the drop from 1440p to 4K is 51 FPS, showing a nearly linear scaling penalty per resolution step. This suggests that the rendering load scales consistently with pixel count, and the RX 6800 XT’s 512.0 GB/s memory bandwidth and 20.74 TFLOPS of FP32 compute are being taxed progressively harder.

High settings show a similar trend: 137 FPS at 1080p, 94 FPS at 1440p, and 55 FPS at 4K. The 4K figure is particularly telling, as it falls just below the 60 FPS target that most gamers consider the minimum for smooth play. Ultra settings are the most demanding, with averages of 130 FPS, 89 FPS, and 52 FPS across the three resolutions. The gap between High and Ultra at 4K is only 3 FPS, while at 1080p it is 7 FPS, indicating that the Ultra preset adds diminishing visual returns relative to its performance cost at higher resolutions.

The scaling pattern strongly suggests that the CPU is not a limiting factor at any resolution tested. The Core Ultra 9 290K Plus, with its 24 cores and 24 threads boosting to 5.80 GHz, has ample headroom to feed the GPU at 1080p and 1440p. The evidence is that even at 4K Low, the system still produces 95 FPS, which is far above the point where CPU bottlenecks typically manifest. The real story is the GPU: the RX 6800 XT, while a capable RDNA 2.0 part, cannot maintain high frame rates at 4K with maximum quality settings, as the data shows a hard ceiling around 55 FPS on High and 52 FPS on Ultra.

How This Combo Ranks

In the global database of tested combinations, this CPU-GPU pairing ranks 573rd out of 2851 combos for Thief, placing it in the top 20.1% of all tested systems. This is a strong showing, but not an elite one, reflecting the fact that the RX 6800 XT, while solid, sits at the 85th percentile among all GPUs, and the Core Ultra 9 290K Plus sits at the 96th percentile among all CPUs. The combination of a top-tier CPU with a middle-upper-tier GPU results in a system that ranks well but is clearly GPU-limited in this title.

The CPU’s nearest rivals provide context for its performance ceiling. The Intel Core Ultra 9 285K scores 0.2% higher on average, while the AMD EPYC 4584PX is 1.1% ahead and the AMD EPYC 9135 is 1.2% ahead. The AMD EPYC 7F72 trails by 1.3%. These deltas are all within noise, indicating that the 290K Plus is essentially tied with the previous flagship and other high-end server parts in raw compute. However, for gaming, these differences are negligible, and the data shows that the CPU is not the determining factor in Thief’s frame rates at any resolution.

On the GPU side, the RX 6800 XT’s nearest rivals show a tighter cluster. The NVIDIA RTX A1000 Mobile scores 1.5% higher on average, while the Intel Arc A550M is 2.5% lower, and both the NVIDIA GeForce RTX 5070 Ti and AMD Radeon RX Vega 64 are 3.0% lower. This places the 6800 XT in a competitive but crowded mid-to-high tier. The ranking of 573rd overall suggests that many combinations with newer or higher-end GPUs outperform this pairing in Thief, likely due to the game’s relatively modest CPU requirements, which allow slower CPUs paired with faster GPUs to achieve higher frame rates.

The combo rank of 573 out of 2851 means that 2278 other tested combos perform better in Thief. Given that the CPU is at the 96th percentile, the ranking shortfall must be attributed to the GPU. This is a classic case of pairing a top-tier processor with a mid-high-tier graphics card, where the GPU becomes the binding constraint in a GPU-bound scenario like 4K Ultra.

Settings Recommendations

The measured data provides clear guidance for optimizing the experience across different resolutions. At 1920x1080, all settings presets produce playable frame rates, with even Ultra hitting 130 FPS. However, the jump from Medium at 179 FPS to High at 137 FPS is significant (a 42 FPS drop), while the drop from High to Ultra is a mere 7 FPS. This suggests that High is the sweet spot at 1080p, offering a 137 FPS average that is well above refresh-rate ceilings for most monitors, while Ultra provides only a marginal visual improvement for a noticeable performance loss.

At 2560x1440, the recommendations shift slightly. Low settings yield 162 FPS, Medium 123 FPS, and High 94 FPS. Ultra drops to 89 FPS. For gamers with 144 Hz monitors, Medium at 123 FPS is the best balance, as it stays above 120 FPS while High at 94 FPS is still smooth but not optimal for high refresh rates. Ultra at 89 FPS is viable but offers diminishing returns over High, with only a 5 FPS difference between the two. The data suggests that for 1440p, Medium provides the best experience per frame, as it maintains a comfortable margin above 60 FPS while delivering enhanced visual fidelity over Low.

At 3840x2160, the situation is more constrained. Low settings produce 95 FPS, which is playable, but Medium drops to 72 FPS, High to 55 FPS, and Ultra to 52 FPS. For 4K gaming, the data clearly shows that Medium is the highest playable preset, with 72 FPS providing a smooth experience. High and Ultra both fall below 60 FPS, which may be acceptable for slower-paced stealth gameplay but is not ideal for fluid motion. The 20 FPS gap between Medium and High at 4K is substantial, indicating that the GPU is struggling with the additional shading and texture work. Given that the game is a stealth title where frame pacing matters less than in competitive shooters, Medium at 4K is the recommended compromise, sacrificing some visual quality for a stable frame rate.

Measured FPS Breakdown

At 1920x1080, the full range of settings was measured with complete data. Low settings produced an average of 236 FPS, with no min or max reported. Medium settings averaged 179 FPS, with a minimum of 153 FPS and a maximum of 206 FPS. High settings averaged 137 FPS, and Ultra averaged 130 FPS. The Medium preset’s min FPS of 153 is notably high, indicating that even in demanding scenes, the frame rate rarely dips below the refresh-rate threshold of most monitors.

At 2560x1440, the measurements show a similar pattern. Low averaged 162 FPS, Medium averaged 123 FPS with a minimum of 105 FPS and maximum of 142 FPS, High averaged 94 FPS, and Ultra averaged 89 FPS. The Medium min FPS of 105 is still above 60, ensuring a fluid experience even in busy stealth sequences. The gap between High and Ultra narrows to just 5 FPS at this resolution, suggesting that the Ultra preset’s additional effects are not heavily taxing the GPU.

At 3840x2160, the data reveals the GPU’s limits. Low averaged 95 FPS, Medium averaged 72 FPS with a minimum of 62 FPS and maximum of 83 FPS, High averaged 55 FPS, and Ultra averaged 52 FPS. The Medium min FPS of 62 is just above the 60 FPS threshold, but High and Ultra both sit below it, with averages of 55 and 52 FPS respectively. The 4K Medium max FPS of 83 indicates that the system can occasionally hit higher frame rates, but the average is what matters for sustained gameplay.

CPU Role

The Intel Core Ultra 9 290K Plus is a 24-core, 24-thread processor based on the Arrow Lake Refresh architecture, built on a 3 nm process node. It has a base clock of 3.70 GHz and a boost clock of 5.80 GHz, with a TDP of 125 W. The CPU features a large L3 cache of 36 MB shared, and per-core L2 cache of 3 MB. Its benchmark scores are impressive: a Cinebench R23 multi-core score of 51731 and a single-core score of 7303, placing it at the 96th percentile among all CPUs.

In Thief, the CPU’s role is to feed the GPU with draw calls and game logic. The measured FPS data shows that at 1080p Low, the system achieves 236 FPS, which is a frame rate that would stress most CPUs. The fact that the 290K Plus can maintain this level of performance indicates that its single-thread performance, as evidenced by the Cinebench R15 single-core score of 736 and PassMark single-thread score of 4823, is more than adequate for the game’s engine. The game, released in 2014, likely does not utilize all 24 cores effectively, but the high boost clock of 5.80 GHz ensures that the few cores it does use are running at maximum speed.

The CPU’s memory bandwidth of 115.2 GB/s and dual-channel DDR5 support are also relevant, as Thief’s open-world environments can be memory-intensive. However, the GPU’s 512.0 GB/s bandwidth is over four times higher, making it the primary conduit for texture data. The CPU’s role is further diminished by the fact that even at 4K Low, the system still produces 95 FPS, which is well above the point where CPU limitations would manifest. The nearest CPU rivals, such as the Core Ultra 9 285K with a 0.2% higher average score, show that the 290K Plus is not leaving any performance on the table in synthetic benchmarks, and this translates to a negligible impact on Thief’s frame rates.

The data conclusively shows that the Core Ultra 9 290K Plus is not a limiting factor in this pairing. The GPU is the bottleneck at all resolutions above 1080p Low, and even at 1080p, the CPU’s performance headroom is vast. For a game like Thief, which is not heavily threaded, the CPU’s high clock speed and strong single-core performance are the key attributes, and both are excellent. The 24 cores are largely unused, but their presence does not hurt performance, and the power efficiency of the 3 nm process ensures that thermal throttling is unlikely to occur during extended gaming sessions.
