How This Combo Ranks

The data places this specific CPU and GPU pairing at the 1815th position out of 2851 combos tested in Thief. This rank is a strong indicator that the overall system performance is not exceptional for this title. To understand why, it's helpful to look at the individual components. The Intel Core Ultra 9 290K Plus is a formidable processor, sitting in the 96th percentile of all CPUs with an average benchmark score of 84003. It outperforms its nearest rival, the Intel Core Ultra 9 285K, by a mere 0.2%, showing it is at the top of its class.

In contrast, the AMD Radeon RX 6650 XT is a more mid-range part, landing in the 65th percentile of all GPUs with an average score of 19765. Its closest competitors, such as the NVIDIA Tesla K40m, are within a 0.7% performance delta, indicating it is a solid but not class-leading graphics solution. The combination of a top-tier CPU with a mid-tier GPU creates a bottleneck. The 1815th rank out of 2851 suggests that the GPU is holding the system back from achieving a higher standing. While the CPU is capable of feeding the GPU with data, the GPU's raw processing power limits the final frame output, especially when compared to systems pairing this CPU with much more powerful graphics cards. The rank is a direct consequence of this component mismatch.

Resolution Scaling

The measured FPS data reveals a classic pattern of GPU-bound performance scaling with resolution. At 1920x1080, the system delivers an average of 93 FPS on High settings. Moving up to 2560x1440, the average drops to 64 FPS. At 3840x2160 (4K), the average falls further to 38 FPS. This is a sharp decline, with the 4K result being only about 41% of the 1080p performance.

This scaling behavior clearly indicates that the AMD Radeon RX 6650 XT is the limiting factor as resolution increases. The workload on the GPU grows exponentially with pixel count, and the RX 6650 XT's compute resources and memory bandwidth become saturated. The CPU, with its 24 cores and high boost clock of 5.80 GHz, is not the primary constraint at these higher resolutions. The performance drop is almost entirely attributable to the GPU's inability to keep up with the increased rendering demand. The difference between 1080p and 1440p is a 29 FPS drop, but the difference between 1440p and 4K is a 26 FPS drop. The scaling is consistent, showing the GPU is the primary bottleneck across all resolutions, though the frame rates at 1080p suggest the CPU is capable of much more.

Measured FPS Breakdown

The benchmark results provide a comprehensive look at performance across different settings and resolutions. At 1920x1080, the Low preset delivers a very high average of 162 FPS, which drops to 123 FPS on Medium. High settings yield 93 FPS, and Ultra brings the average down to 89 FPS. The 1080p Medium preset also shows a minimum FPS of 104 and a maximum of 141.

At 2560x1440, the performance scales down as expected. The Low preset averages 111 FPS, Medium averages 84 FPS, High averages 64 FPS, and Ultra averages 61 FPS. The Medium preset at this resolution reports a minimum of 72 FPS and a maximum of 97 FPS. This shows that the 1440p Medium setting is still quite playable.

The most demanding tests are at 3840x2160. Here, the Low preset manages an average of 65 FPS, but Medium drops to 49 FPS, High to 38 FPS, and Ultra to 36 FPS. The 4K Medium preset has a recorded minimum of 42 FPS and a maximum of 57 FPS. These numbers show that 4K gaming is only feasible on the Low preset, and even then, it's borderline for a smooth 60 FPS experience. The data across all resolutions shows a consistent performance hierarchy, with the Ultra preset demanding a significant premium over High.

GPU Role

The AMD Radeon RX 6650 XT is clearly the defining component in this system's gaming performance. Its role is dictated by its specifications and the measured results. The GPU features a base clock of 2055 MHz and a boost clock of 2635 MHz, with a game clock of 2410 MHz. It has 8 GB of GDDR6 memory on a 128-bit bus, providing a bandwidth of 280.3 GB/s.

In Thief, the GPU's limitations are most evident at 4K. The 8 GB VRAM buffer is likely a constraint at this resolution, as the game's assets can require significant memory. The bandwidth of 280.3 GB/s is also a factor; at 4K, the GPU must move a massive amount of texture data, and this bandwidth can become a bottleneck. The benchmark results support this, showing a dramatic performance drop at 3840x2160 compared to lower resolutions. The GPU's FP32 performance of 10.79 TFLOPS provides a baseline for its compute capability, which is insufficient for maintaining high frame rates at 4K with higher presets. Its 2048 shading units are busy with the increased pixel count, resulting in the low averages of 38 FPS and 36 FPS on High and Ultra settings, respectively. The RX 6650 XT is a capable 1080p and 1440p card, but the data shows it is out of its depth at 4K in this title.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend heavily on the target resolution and desired frame rate. For a smooth 60 FPS experience at 1920x1080, the High preset is a solid choice, delivering an average of 93 FPS. However, for players with high refresh rate monitors, the Low preset at 162 FPS or Medium at 123 FPS are excellent options.

At 2560x1440, the Medium preset is the recommended choice, as it provides a very playable average of 84 FPS with a minimum of 72 FPS. The High preset, at 64 FPS, is also viable for those who prioritize visual fidelity over a higher frame rate. The Ultra preset at 61 FPS is just at the edge of playability but might suffer from occasional dips.

For 3840x2160, the data suggests that the Low preset is the only viable option, with an average of 65 FPS. Even this setting may not provide a consistently smooth experience. The Medium preset at 49 FPS is below the 60 FPS target and is not recommended for a fluid experience. The High and Ultra presets are effectively unplayable at this resolution, with averages of 38 FPS and 36 FPS, respectively. Therefore, the best experience is achieved by using the Medium preset at 1440p, which balances visual quality with a frame rate that stays well above 60 FPS.

CPU Role

The Intel Core Ultra 9 290K Plus is a high-end processor that provides more than enough performance for Thief. Its 24 cores and 24 threads, with a base clock of 3.70 GHz and a boost clock of 5.80 GHz, are far more than this game requires. The CPU's benchmark scores are exceptional, with a Cinebench R23 multi-core score of 51731 and a single-core score of 7303. It ranks in the 96th percentile of all CPUs.

The data shows that the CPU is not the bottleneck at any resolution. At 1080p, the GPU is able to produce frame rates up to 162 FPS on Low settings, which is a high enough load to keep the CPU's single-core performance engaged. However, as the resolution increases, the GPU becomes the limiting factor, and the CPU's utilization likely decreases. The CPU's massive multi-threading capabilities are largely untapped in this game, as Thief is not a title that scales well across many cores. The 0.2% performance delta over the Intel Core Ultra 9 285K is irrelevant in this gaming scenario; the CPU's role is simply to feed the GPU without becoming a limiting factor. Its high single-thread performance, as evidenced by its Passmark single-thread score of 4823, ensures that the game's main logic thread has ample headroom, allowing the GPU to be the sole determinant of final frame rates.
