Thief

# Thief Performance Analysis: AMD Ryzen AI Max+ 395 + NVIDIA GeForce RTX 4070 Mobile

This combination delivers a playable but resolution-sensitive experience in Thief, with the data showing a clear progression from excellent 1080p performance to marginal 4K Ultra results. The pairing ranks in the 50th percentile of tested combos, placing it squarely in the mid-pack for this 2014 stealth title. The bottleneck shifts decisively toward the GPU as resolution increases, while the 16-core CPU remains largely underutilized throughout the tested range.

Resolution Scaling

The FPS drop from 1080p to 4K reveals a system that is heavily GPU-limited at higher resolutions. At High settings, the average frame rate falls from 106 FPS at 1920x1080 to 73 FPS at 2560x1440, then to 43 FPS at 3840x2160. That represents a 31% reduction from 1080p to 1440p, and a further 41% reduction from 1440p to 4K. The cumulative drop from 1080p to 4K is 59%, which is a substantial penalty that points squarely at the RTX 4070 Mobile's 8 GB VRAM and 128-bit memory bus as the limiting factor.

The scaling pattern is consistent across all settings presets. At Low settings, the drop from 184 FPS at 1080p to 126 FPS at 1440p to 74 FPS at 4K shows a similar percentage decline — 32% and 41% respectively. This consistency suggests that the GPU's compute and memory bandwidth constraints, rather than any specific setting, are what govern performance at higher resolutions. The RTX 4070 Mobile's 256.0 GB/s memory bandwidth matches the CPU's memory bandwidth figure, but the GPU must also handle texture bandwidth and frame buffer operations, making it the clear bottleneck.

At Medium settings, the only preset with complete min/max data, the frame rate range narrows as resolution increases. At 1080p, the spread from minimum 119 FPS to maximum 161 FPS represents a 35% variance. At 1440p, the spread narrows to 82-110 FPS, a 34% variance. At 4K, the range tightens further to 48-65 FPS, a 35% variance. The relative consistency of these ranges suggests that the frame pacing remains stable even as the average drops, which is a positive indicator for gameplay smoothness.

The scaling behavior indicates that for 4K play, only Low settings approach what might be considered a fluid experience at 74 FPS average. High and Medium at 4K produce averages of 43 and 56 FPS respectively, which fall short of ideal smoothness for a stealth game requiring precise timing. Ultra at 4K drops to 41 FPS, barely crossing the threshold of playability.

CPU Role

The AMD Ryzen AI Max+ 395 brings substantial processing power to this pairing, with 16 cores and 32 threads based on the Zen 5 architecture. The CPU's boost clock of 5.10 GHz and base clock of 3.00 GHz provide strong single-threaded performance, which is typically what matters most for game logic and AI in a 2014 title like Thief. The processor's benchmark scores reinforce this capability: a Geekbench single-core score of 2464 and a Cinebench R23 single-core score of 2044 indicate robust per-thread performance.

The CPU's multi-threaded capabilities are equally impressive, with a Cinebench R23 multi-core score of 35314 and a Geekbench multi-core score of 20992. However, Thief, being a title from 2014, does not scale well across 32 threads. The game's engine was designed for an era when quad-core processors were the norm, so the vast majority of the CPU's compute capacity remains idle during gameplay. The PassMark physics score of 3481, while moderate, suggests the CPU can handle the game's physics calculations without strain.

The L3 cache of 64 MB shared across the chip is more than sufficient for Thief's working set, and the 80 KB L1 and 1 MB L2 per core provide low-latency access to frequently used data. The quad-channel LPDDR5X memory support with 256.0 GB/s bandwidth ensures that memory bandwidth is not a constraint, particularly at lower resolutions where the GPU is not saturated.

The CPU's 95th percentile ranking among all tested processors places it in elite company. Its nearest rivals include the Intel Core i9-14900K, which scores 1.7% higher on average, and the AMD Ryzen 9 8945HX, which scores 2% lower. This positioning confirms that the CPU is not the limiting factor in this gaming scenario — the data shows that even at 1080p Low, where the CPU would be most likely to bottleneck, the system achieves 184 FPS, indicating headroom remains.

How This Combo Ranks

This specific combination of AMD Ryzen AI Max+ 395 and NVIDIA GeForce RTX 4070 Mobile ranks 1876 out of 3720 tested combos in Thief, placing it in the 50th percentile. This mid-pack positioning is somewhat surprising given the individual capabilities of both components. The CPU sits in the 95th percentile of all processors, and the GPU in the 73rd percentile of all graphics cards, yet their combination in this game produces only average results relative to other systems.

The explanation lies in the game's age and the GPU's mobile form factor. Thief's engine does not heavily utilize the CPU's 16 cores, and the RTX 4070 Mobile, despite its strong PassMark G3D score of 19587, is constrained by its 8 GB VRAM and 128-bit memory interface. The GPU's benchmark scores place it near the AMD Radeon RX 6700 XT (0% delta) and NVIDIA GeForce RTX 3090 (0.5% ahead), which are desktop-class parts. Yet in this laptop configuration, thermal and power constraints inherent to mobile designs likely prevent sustained peak performance.

The 50th percentile ranking means that half of all tested combinations perform better in Thief, and half perform worse. This is a meaningful data point for anyone evaluating this hardware pairing for this specific game. The ranking reflects the reality that Thief is more sensitive to GPU memory bandwidth than to raw compute, and the RTX 4070 Mobile's 256.0 GB/s bandwidth, while respectable for a mobile part, does not match the bandwidth of higher-performing desktop GPUs.

Measured FPS Breakdown

At 1920x1080, the system delivers strong performance across all settings. Low settings produce an average of 184 FPS, which is more than sufficient for any display refresh rate. Medium settings average 140 FPS with a minimum of 119 FPS and maximum of 161 FPS, providing a smooth experience with headroom for frame drops. High settings average 106 FPS, still comfortably above 60 FPS. Ultra settings average 101 FPS, a minimal penalty of only 5 FPS compared to High, suggesting that the Ultra preset's additional effects are not particularly demanding at this resolution.

At 2560x1440, performance remains playable but the gap between settings widens. Low averages 126 FPS, Medium averages 96 FPS with a range of 82-110 FPS, High averages 73 FPS, and Ultra averages 70 FPS. The drop from Low to High is 42%, indicating that the GPU is beginning to feel the pressure of higher pixel counts. The 3 FPS difference between High and Ultra at this resolution is negligible, suggesting that the Ultra preset's marginal visual improvements come at little cost.

At 3840x2160, the picture changes dramatically. Low averages 74 FPS, which is still playable. Medium averages 56 FPS with a range of 48-65 FPS, putting the minimum below the 60 FPS threshold. High averages 43 FPS, and Ultra averages 41 FPS. The difference between High and Ultra at 4K is only 2 FPS, indicating that both presets are limited by the same GPU constraint. The step from Medium to High at 4K costs 13 FPS, a 23% reduction, which is the largest single-setting penalty in the entire dataset.

The Medium preset is the only one with complete min/max data across all resolutions. This allows for a detailed look at frame time consistency. At 1080p, the 42 FPS spread between minimum and maximum indicates some variance but nothing that would cause noticeable stutter. At 1440p, the 28 FPS spread is tighter. At 4K, the 17 FPS spread is the narrowest, meaning that while the average is lower, the frame delivery is actually more consistent at higher resolutions.

GPU Role

The NVIDIA GeForce RTX 4070 Mobile is the primary determinant of gaming performance in this pairing. Its Ada Lovelace architecture, built on a 5 nm process at TSMC, packs 22,900 million transistors into a 188 mm² die. The GPU operates at a base clock of 1395 MHz and boost clock of 1695 MHz, with 4608 shading units, 144 texture mapping units, and 48 raster output units. These specifications translate to a pixel rate of 81.36 GPixel/s and a texture rate of 244.1 GTexel/s.

The GPU's 8 GB of GDDR6 memory on a 128-bit bus provides 256.0 GB/s of bandwidth. This is the same bandwidth figure as the CPU's memory subsystem, but the GPU must share this bandwidth across frame buffer operations, texture sampling, and compute workloads. In Thief, which was released in 2014 and features environments with substantial texture detail, the 8 GB capacity is sufficient, but the bandwidth becomes a constraint at 4K resolution where the pixel throughput demands are highest.

The GPU's benchmark results paint a picture of solid mid-range performance. Its PassMark G3D score of 19587 places it in the 73rd percentile of all GPUs. The Geekbench OpenCL score of 109197 and Vulkan score of 108367 indicate strong compute capabilities. The PassMark DirectX 11 score of 179 and DirectX 12 score of 85 show that the GPU handles modern APIs well, though Thief's engine predates these benchmarks.

The RTX 4070 Mobile's nearest rivals in the benchmark database are instructive. The AMD Radeon RX 6700 XT matches its average score exactly (0% delta), while the NVIDIA GeForce RTX 3090 scores 0.5% higher. This positioning suggests that the mobile GPU performs on par with desktop parts from the previous generation, which is an impressive feat given the thermal and power constraints of a laptop form factor. The 115 W TDP is modest for the performance delivered.

In Thief specifically, the GPU's 128-bit memory bus is the most likely bottleneck at 4K. The game's environments feature complex lighting and shadow effects that require frequent memory access, and the 256.0 GB/s bandwidth simply cannot sustain high frame rates at 4K Ultra. The data supports this interpretation: the performance gap between 1080p and 4K is consistent across all settings, indicating a fixed hardware limit rather than a software inefficiency.

Settings Recommendations

The measured data supports a clear hierarchy of settings for this hardware combination. At 1920x1080, any preset is viable, but Ultra at 101 FPS average is the best choice for visual fidelity without meaningful performance sacrifice. The 5 FPS difference between High and Ultra is negligible, making Ultra the obvious pick for 1080p gaming.

At 2560x1440, the recommendation shifts to High settings. The 73 FPS average is smooth, and the step up to Ultra only costs 3 FPS, so those with 144 Hz displays might prefer the minimal visual gains of Ultra. However, for those prioritizing frame rate stability, High provides a better margin above the 60 FPS threshold. Medium at 96 FPS is also viable for competitive play, but the visual downgrade from High is noticeable.

At 3840x2160, the choices are more constrained. Low at 74 FPS is the only preset that consistently exceeds 60 FPS, making it the safe recommendation for 4K play. Medium at 56 FPS average with a 48 FPS minimum is borderline — playable but with noticeable frame drops during intense scenes. High at 43 FPS and Ultra at 41 FPS are not recommended for 4K, as the frame rates fall below what is typically considered smooth for a stealth game requiring precise movement and timing.

The optimal experience across the entire resolution range is Medium settings. At 1080p, Medium delivers 140 FPS with a 119 FPS minimum, providing a wide safety margin. At 1440p, Medium averages 96 FPS with an 82 FPS minimum, still comfortably above 60 FPS. At 4K, Medium's 56 FPS average and 48 FPS minimum are the best balance of visual quality and performance among the non-Low presets. The 35% frame time variance at Medium across all resolutions indicates consistent pacing, which is crucial for a game where timing-based stealth mechanics are central to the experience.

For users with 60 Hz displays, Medium at 4K or High at 1440p both provide acceptable experiences, with the former offering higher resolution and the latter offering better visual detail. For users with high refresh rate displays, 1080p Ultra or 1440p Medium are the best choices, delivering frame rates well in excess of 100 FPS. The data does not support 4K Ultra as a viable option for this hardware, as the 41 FPS average falls short of the 60 FPS target that most players consider the minimum for a smooth experience.
