Thief

Thief, a 2014 stealth title, still demands a balanced system at higher resolutions. The measured data for the AMD Ryzen 9 8945HX and NVIDIA GeForce RTX 5070 Mobile combination shows a clear performance curve across the three tested resolutions. At 1080p, the system is firmly GPU-bound at higher settings, but the CPU's strength becomes apparent at lower presets where frame rates scale dramatically. By 4K, the GPU becomes the definitive bottleneck, with even the Low preset struggling to maintain high refresh rates.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep and consistent across all settings, indicating that the RTX 5070 Mobile's 8 GB GDDR7 memory and 128-bit bus are the primary limiting factors at higher pixel counts. At High settings, the average FPS falls from 105 at 1080p to 72 at 1440p, a 31% reduction, and then to 42 at 4K, a further 42% drop from the 1440p figure. This scaling pattern is typical of a GPU that is being saturated by pixel throughput requirements.

The Low preset tells a more interesting story. At 1080p, the system achieves 181 FPS, which drops to 124 at 1440p (a 31% decrease) and then to 73 at 4K (a 41% decrease from 1440p). The percentage drops are nearly identical to the High preset, which suggests that even at Low settings, the GPU is the primary constraint. The RTX 5070 Mobile's 48 ROPs and 13.13 TFLOPS of FP32 compute are simply not enough to push 4K at high frame rates, regardless of the graphical workload.

Medium settings show the most complete data, with minimum and maximum frame times recorded. At 1080p Medium, the average is 138 FPS with a minimum of 117 and maximum of 158. At 1440p Medium, the average drops to 94 FPS (a 32% reduction) with a range of 80-109. At 4K Medium, the average falls to 56 FPS (a 40% reduction from 1440p) with a range of 47-64. The consistent 30-40% scaling losses between each resolution step confirm that the GPU's memory bandwidth of 384.0 GB/s is being overwhelmed as pixel count increases.

Ultra settings follow the same trajectory: 100 FPS at 1080p, 68 FPS at 1440p, and 40 FPS at 4K. The 4K Ultra result of 40 FPS is barely playable for a stealth game, and the 1440p Ultra figure of 68 FPS is the first preset where playability becomes questionable. The data strongly suggests that 1080p is the sweet spot for this combo, with 1440p being acceptable for High and Medium presets, while 4K should be reserved for Low settings or lower-fidelity gaming.

CPU Role

The AMD Ryzen 9 8945HX is a 16-core, 32-thread processor based on the Zen 4 architecture, codenamed Dragon Range. It operates at a base clock of 2.50 GHz and boosts to 5.40 GHz, with 64 MB of L3 cache. This is a high-end mobile CPU, and its benchmark results reflect that: it scores 42713 in Cinebench R23 multi-core and 6030 in single-core, placing it in the 95th percentile of all CPUs.

In Thief, the CPU's role becomes evident when examining the scaling between Low and Ultra settings at 1080p. The jump from 100 FPS at Ultra to 181 FPS at Low represents an 81% improvement, which is far more than the GPU alone could deliver if it were the sole bottleneck. This indicates that at lower settings, the CPU is capable of feeding the GPU with far more frames than the GPU can render at higher settings. The Ryzen 9's 5.40 GHz boost clock and strong single-core performance are directly responsible for this headroom.

However, the CPU's advantage diminishes as resolution increases. At 4K, the difference between Low and Ultra is only 73 FPS versus 40 FPS, a 45 FPS gap that is almost entirely GPU-driven. The processor's 16 cores and 32 threads are largely irrelevant at 4K because the GPU cannot keep up with the CPU's output. The PassMark multithread score of 51405 and integer math score of 195180 suggest the CPU has ample computational power, but Thief is not a game that scales with core count beyond a certain point.

The nearest rivals for the CPU include the Intel Core Ultra 9 285HX (0.1% ahead), AMD EPYC Embedded 8224P (0.4% behind), AMD Ryzen Threadripper PRO 9945WX (0.4% behind), and AMD Ryzen 9 9950X3D (0.6% ahead). These are all flagship-level processors, and the 8945HX's performance is within 1% of each of them. This means the CPU is not a weak link in this combo; it is a top-tier part that will not bottleneck the GPU in most scenarios, except at very low resolutions where the frame rate ceiling is exceptionally high.

How This Combo Ranks

The combination of the Ryzen 9 8945HX and RTX 5070 Mobile ranks 1938 out of 3720 tested combos in Thief, placing it in the 52nd percentile overall. This is a middling rank for two components that are individually strong, which suggests that the pairing is not optimized for this specific game. The CPU ranks in the 95th percentile of all CPUs, and the GPU ranks in the 75th percentile of all GPUs, so the combo ranking is dragged down by the GPU's relative weakness in Thief.

The GPU's nearest rivals provide context for its performance. The RTX 5070 Mobile's average benchmark score of 29928 is nearly identical to the NVIDIA GeForce RTX 3070 Ti (29945, 0.1% behind), the RTX 2080 Ti (29783, 0.5% ahead), and the AMD Radeon RX 6800 (30095, 0.6% behind). This places the mobile GPU in the same performance tier as these desktop cards from previous generations. In Thief specifically, the 4K results (42 FPS at High) align with this mid-range positioning.

The combo rank of 1938 out of 3720 means that roughly half of the tested combinations perform better in Thief. This is not surprising given that Thief is a 2014 title that was designed for older hardware, and many modern high-end desktops with faster GPUs will outperform this mobile setup. However, for a laptop configuration, the data shows that this combo is competitive with mid-range desktop GPUs from a few generations ago, which is a reasonable expectation for a mobile RTX 5070.

Measured FPS Breakdown

At 1920x1080, the system delivers playable frame rates across all presets. Low settings produce an average of 181 FPS, which is far beyond the refresh rate of most laptops. Medium averages 138 FPS with a minimum of 117 and maximum of 158, offering a smooth experience with some headroom for dips. High averages 105 FPS, and Ultra averages 100 FPS. The gap between High and Ultra is only 5 FPS, suggesting that the Ultra preset's additional effects are not heavily taxing the GPU at this resolution.

At 2560x1440, performance drops significantly but remains usable for most presets. Low averages 124 FPS, which is still excellent for competitive play. Medium averages 94 FPS with a minimum of 80 and maximum of 109, providing a stable experience. High averages 72 FPS, which is borderline for a smooth 60 FPS target, and Ultra averages 68 FPS. The 4 FPS difference between High and Ultra at 1440p mirrors the 5 FPS difference at 1080p, indicating that the Ultra preset's overhead is consistent regardless of resolution.

At 3840x2160, the GPU struggles to maintain high frame rates. Low averages 73 FPS, which is the only preset that hits a comfortable 60+ FPS target. Medium averages 56 FPS with a minimum of 47 and maximum of 64, meaning it will dip below 60 FPS during intense scenes. High averages 42 FPS, and Ultra averages 40 FPS. The 4K results are the clearest indicator of the GPU's limits; anything above Low settings will result in sub-60 FPS experiences at 4K.

The Medium preset is the only one with complete min/max data at all three resolutions, which allows for a detailed analysis of frame time consistency. At 1080p, the range is 117-158 FPS (a 41 FPS spread), at 1440p it is 80-109 FPS (a 29 FPS spread), and at 4K it is 47-64 FPS (a 17 FPS spread). The absolute spread narrows as resolution increases, but the percentage spread relative to the average grows, indicating less consistent frame pacing at higher resolutions.

Settings Recommendations

For a smooth 60+ FPS experience, the Low preset at 4K is the only viable option, delivering 73 FPS. If you prefer higher visual fidelity at 4K, Medium is playable at 56 FPS but will dip to 47 FPS in demanding scenes, which may be acceptable for a stealth game that does not require twitch reflexes. High and Ultra at 4K should be avoided, as they produce 42 and 40 FPS respectively, which feels sluggish.

At 1440p, the Medium preset is the best balance, offering 94 FPS with a minimum of 80 and maximum of 109. This provides a comfortable margin above 60 FPS and maintains visual quality. High and Ultra at 1440p are playable at 72 and 68 FPS, but the frame rate is closer to the 60 FPS threshold, leaving less headroom for drops. Low at 1440p is overkill at 124 FPS and sacrifices too much visual quality for a game that is not competitive.

At 1080p, the Ultra preset is the recommended choice, as it delivers 100 FPS while providing the best visual experience. The difference between High and Ultra is only 5 FPS, so there is no reason to drop below Ultra at this resolution. Medium and Low are unnecessary at 1080p, as they push frame rates to 138 and 181 FPS respectively, which exceeds the refresh rate of most laptop displays. For the best experience, the data supports using Ultra at 1080p or Medium at 1440p, depending on your preference for resolution versus visual detail.
