Thief

Thief, a 2014 stealth title, is an older game, but its performance with the Intel Core Ultra 7 265HX and NVIDIA GeForce RTX 5090 reveals how modern high-end hardware handles legacy engines. The data shows that this combination delivers very high frame rates across all tested configurations, with the limiting factor shifting from the CPU to the GPU only at the most demanding settings. This analysis breaks down the measured results to explain the role of each component and provide practical settings advice for the best experience.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core Ultra 7 265HX is a 20-core, 20-thread mobile processor based on the Arrow Lake-HX architecture. It has a base clock of 2.60 GHz and a boost clock of 5.30 GHz, with a 30 MB shared L3 cache. In the context of Thief, a game released in 2014, the CPU is rarely the primary bottleneck. The game's engine is not designed to utilize 20 threads effectively, but the 265HX's robust single-thread performance, evidenced by a Cinebench R23 single-core score of 5737, ensures that the game's primary rendering thread is never starved.

The data supports this interpretation. At 1080p with Low settings, the combination achieves 224 FPS, a figure that climbs to 147 FPS at Ultra settings. Even at the highest settings, the frame rate does not collapse, indicating the CPU is managing the game's draw calls and physics without issue. The processor's Passmark single-thread score of 4500 and its 93rd percentile ranking among all CPUs reinforce its capability in this scenario. While the 20 cores are largely underutilized in Thief, the high clock speeds and efficient architecture prevent any CPU-bound stutters, allowing the GPU to operate at its full potential. The CPU's role here is to provide a solid, unbothered foundation, which it does admirably given its performance metrics.

How This Combo Ranks — use comboRankInGame vs other tested combos

Within the benchmark database, this specific pairing of the Intel Core Ultra 7 265HX and the NVIDIA GeForce RTX 5090 holds a combo rank of 413 out of 3720 tested combinations in Thief. This places it in the top 11.1% of all tested systems, a strong showing that underscores its high-end status. The rank is not higher, likely because Thief is an older title where the massive parallel processing power of the RTX 5090 cannot be fully leveraged, and other combos with slightly different CPU or GPU pairings may have an edge in this specific game's engine.

The CPU itself, when compared to its nearest rivals, shows a near-tie in average benchmark scores. The Intel Core Ultra 7 265HX has an average benchmark score of 63173, which is 0.1% higher than the Intel Core i7-13790F’s 63080 and 0.7% higher than the Intel Core Ultra 7 255HX’s 62738. However, it is 0.2% lower than the AMD Ryzen AI 7 450G’s 63331. These are marginal differences, indicating that the CPU is not a differentiating factor in this game's performance. The GPU, similarly, has an average benchmark score of 79842, which is 1.1% higher than the AMD Radeon RX 6850M XT’s 78940 but 1.4% lower than the AMD Radeon Pro Vega 64X’s 80959. The combination’s rank of 413 suggests that while the hardware is exceptionally powerful on paper, the game's engine and the specific interplay of these components result in a performance tier that is very good but not the absolute top.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The scaling of frame rates from 1080p to 4K clearly identifies the GPU as the primary limiting factor when resolution increases. At High settings, the average FPS drops from 154 at 1920x1080 to 106 at 2560x1440 and then to 62 at 3840x2160. This represents a 31% drop from 1080p to 1440p and a further 42% drop from 1440p to 4K. This steep decline is characteristic of a GPU-bound scenario, where the rendering resolution directly impacts the workload on the graphics card.

The data shows a similar pattern at Medium settings, where FPS falls from 202 at 1080p to 139 at 1440p and 82 at 4K. The decline is consistent, indicating that the CPU is maintaining its performance headroom while the GPU is being pushed harder. At Low settings, the trend is even more pronounced: 224 FPS at 1080p drops to 183 at 1440p and 108 at 4K. The fact that the frame rates scale down predictably with pixel count, rather than plateauing, confirms that the RTX 5090's workload is the limiting factor. The CPU is capable of feeding the GPU at all resolutions, but the GPU's rendering throughput is what determines the final frame rate. This analysis shows that for a title like Thief, the 20-core CPU is more than sufficient, and the RTX 5090's performance is the deciding factor, especially at 4K.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a complete picture of performance across three resolutions and four settings presets. At 1920x1080, the combination is exceptionally fast. At Low settings, it averages 224 FPS. Moving to Medium, the average is 202 FPS, with a minimum of 172 FPS and a maximum of 233 FPS. High settings yield 154 FPS, and Ultra settings drop the average to 147 FPS. These numbers show that even at the highest settings, the system is far above the 60 FPS threshold, making for an incredibly smooth experience on high-refresh-rate monitors.

At 2560x1440, performance remains very strong. Low settings produce an average of 183 FPS. Medium settings average 139 FPS, with a minimum of 118 FPS and a maximum of 160 FPS. High settings deliver 106 FPS, and Ultra settings average 101 FPS. The system still maintains over 100 FPS at the highest quality preset, which is excellent for a 1440p display. At 3840x2160, the demands of 4K become apparent. Low settings average 108 FPS, and Medium settings average 82 FPS, with a minimum of 70 FPS and a maximum of 94 FPS. High settings drop to an average of 62 FPS, and Ultra settings average 59 FPS. At 4K Ultra, the system is right at the edge of the 60 FPS target, indicating that this is the most demanding configuration tested.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 5090 is a monster of a GPU, with 32 GB of GDDR7 memory on a 512-bit bus, providing a bandwidth of 1.79 TB/s. Its boost clock is 2407 MHz, and it features 21760 shading units. In Thief, this hardware is overkill in many respects. The game from 2014 does not require 32 GB of VRAM, nor does it stress the 104.8 TFLOPS of FP32 compute power. The GPU's performance is instead dictated by its raw rasterization speed, which is immense.

The benchmark results show that the RTX 5090’s performance in Thief is not limited by its memory or compute capabilities, but by the game's engine itself. The GPU is so fast that at 1080p, the frame rates are likely capped by the CPU's ability to issue draw calls, even with the 265HX’s strong single-thread performance. As resolution increases, the GPU's rendering pipeline becomes the bottleneck. The 1.79 TB/s of memory bandwidth ensures that texture streaming is never an issue, even at 4K with High settings. The GPU’s Passmark G3D score of 39650 and its 92nd percentile ranking indicate its overall power, but in this specific title, its advantage is most visible at 4K, where it manages to push over 100 FPS on Low settings and stays near 60 FPS on Ultra. The data suggests that the RTX 5090 is more than capable of handling Thief, and its role is to provide a massive performance buffer that guarantees high frame rates at any resolution.

Settings Recommendations — which preset gives the best experience per the measured rows

For the best experience in Thief with this hardware, the choice of settings depends on the target resolution and refresh rate. At 1920x1080, the Ultra preset is the clear winner, providing an average of 147 FPS. This is well above the 144 Hz refresh rate of many gaming monitors, and the visual improvements from Ultra over High (which averages 154 FPS) are generally worth the small performance cost. There is no reason to sacrifice visual quality at this resolution, as the system has ample headroom.

At 2560x1440, the Ultra preset continues to be the best choice, with an average of 101 FPS. This is still above the 60 FPS target and provides a fluid experience. While High settings average 106 FPS, the difference is minor, and the extra visual fidelity from Ultra is preferable. The Medium preset at 139 FPS is only useful if targeting a 144 Hz refresh rate, but the visual compromise is significant for a game that is not graphically demanding. At 3840x2160, the decision is more nuanced. The Ultra preset averages 59 FPS, which is just below the 60 FPS target. For a smooth 4K experience, dropping to High settings is recommended, as it yields an average of 62 FPS. This maintains a consistent 60 FPS with a modest reduction in visual effects. The Medium preset, at 82 FPS, is the best option for a 4K high-refresh-rate display, offering a substantial frame rate increase for a noticeable but acceptable drop in visual quality. In summary, the data recommends Ultra at 1080p and 1440p, and High at 4K for a balanced experience, with Medium as a fallback for high-refresh-rate 4K gaming.
