Thief

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

The AMD Ryzen 9 9900X3D is a 12-core, 24-thread processor built on the Zen 5 architecture with the Granite Ridge codename. It operates at a 4.40 GHz base clock and boosts to 5.50 GHz, with a 120 W TDP. The chip features a substantial L3 cache of 128 MB, alongside 80 KB of L1 and 1 MB of L2 per core. This cache configuration is particularly relevant for a stealth title like Thief, where physics interactions, AI pathfinding, and object state tracking frequently hit memory hierarchies.

The processor's benchmark profile shows strong single-thread and multi-thread capabilities. In 3DMark, it scores 1269 in single-thread, 2512 in 2-thread, 4885 in 4-thread, 9002 in 8-thread, and 13795 in max-thread tests. Cinebench R23 results show 6739 in single-core and 47737 in multi-core. Geekbench reports 3041 single-core and 22884 multi-core. PassMark single-thread score is 4646, with a multithread score of 56154. The processor's percentile versus all CPUs is 91, placing it in the top decile of tested processors.

For Thief, a game from 2014, the CPU's high single-thread performance is the dominant factor. The game's engine was designed around the era's dual-core and quad-core processors, meaning it rarely scales beyond a handful of threads. The 9900X3D's single-thread score of 1269 in 3DMark and 4646 in PassMark indicates exceptional per-core throughput. This translates to rapid AI decision-making and smooth traversal through the game's dense, interactive environments. The 128 MB L3 cache is also beneficial, as Thief features many small, repeated data access patterns from NPCs, lootable objects, and environmental interactions that benefit from large cache residency.

The 12-core count does not directly accelerate Thief's frame rates, as the game's engine is not designed to utilize 24 threads efficiently. However, the processor's 2-thread and 4-thread scores (2512 and 4885 in 3DMark) show that even when the game limits itself to a few threads, the per-thread performance remains high. The 8-thread score of 9002 indicates that if the game does spawn background tasks, there is ample headroom. The processor's nearest rivals in average benchmark score include the Intel Core Ultra 5 245KF at 55093 (-0.6% delta), the Intel Core Ultra 5 245K at 54053 (1.3% delta), the Intel Xeon 6505P at 53701 (2% delta), and the Intel Core i7-14700F at 53620 (2.1% delta). The 9900X3D's avgBenchmarkScore is 54762, placing it slightly below the Core Ultra 5 245KF but above the other three rivals.

In Thief, the CPU's role is to maintain a consistent frame delivery pipeline. The measured FPS data shows that at 1080p Low settings, the combo achieves 228 FPS average, which is likely near or at the engine's practical ceiling. The CPU's ability to feed the GPU at such high frame rates is demonstrated by the fact that frame rates scale down gracefully as resolution increases, which would not be the case if the CPU were the bottleneck. The 9900X3D's boost clock of 5.50 GHz provides the raw frequency needed for the game's light-threaded workloads, while the 4 nm process node and TSMC foundry ensure power efficiency during long sessions.

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

The AMD Radeon RX 9070 is built on the RDNA 4.0 architecture with the Navi 48 chip, manufactured on a 4 nm process. It features 16 GB of GDDR6 memory on a 256-bit bus, yielding 644.6 GB/s of bandwidth. The GPU's base clock is 1330 MHz, with a boost clock of 2520 MHz and a game clock of 2070 MHz. Memory operates at 2518 MHz, effectively 20.1 Gbps. The GPU has 3584 shading units, 224 texture mapping units, and 128 raster operation units, with 56 ray tracing cores. Its pixel rate is 322.6 GPixel/s and texture rate is 564.5 GTexel/s, delivering 36.13 TFLOPS of FP32 performance.

The RX 9070's 16 GB VRAM is far more than Thief requires, as the game was released in 2014 when 2-4 GB was the norm. The abundant memory capacity means texture streaming and asset loading never cause stutter, even at 4K resolution with Ultra settings. The memory bandwidth of 644.6 GB/s is more than sufficient for the game's relatively modest texture sizes, allowing the GPU to fetch data quickly without becoming a limiting factor.

The GPU's benchmark scores show a mixed profile. In 3DMark Steel Nomad DX12, it scores 6290. Geekbench OpenCL score is 131539, and Vulkan score is 58705. PassMark results show DirectX 10 at 141, DirectX 11 at 281, DirectX 12 at 74, DirectX 9 at 343, G2D at 1280, G3D at 25381, and GPU compute at 14737. The GPU's percentile versus all GPUs is 69, with an avgBenchmarkScore of 23877. Its nearest rivals include the NVIDIA GeForce GTX TITAN Z at 23736 (0.6% delta), the AMD Radeon RX 6800S at 24063 (-0.8% delta), the NVIDIA GeForce RTX 3080 Mobile at 23628 (1.1% delta), and the NVIDIA GeForce RTX 2080 SUPER at 24170 (-1.2% delta). The RX 9070 sits between these rivals in average score.

For Thief, the GPU's role is to render the game's detailed environments, including dynamic lighting, shadow effects, and particle systems. The game's stealth mechanics rely heavily on visibility and sound propagation, which are rendered through complex shader effects. The RX 9070's 128 ROPs ensure high fill rates, which is critical for the game's multiple render passes. The 224 TMUs handle texture filtering efficiently, as Thief uses high-resolution textures that require significant texel throughput.

The GPU's boost clock of 2520 MHz provides substantial computational throughput. The game's DirectX 11 renderer benefits from the GPU's strong performance in that API, as shown by the PassMark DirectX 11 score of 281. The measured frame rates confirm that the GPU can deliver 228 FPS at 1080p Low and 132 FPS at 1080p Ultra, indicating that even at low settings, the GPU's raw power is not fully utilized—the game's engine may impose a frame rate ceiling. At 4K Ultra, the GPU sustains 53 FPS average, showing that the resolution increase does tax the GPU's compute and memory resources appropriately.

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

The measured FPS data reveals a clear pattern of resolution scaling. At 1080p Low, the combo achieves 228 FPS average. Moving to 1440p Low drops the frame rate to 164 FPS, a 28% reduction. At 4K Low, the frame rate further drops to 97 FPS, which is 57% lower than 1080p Low. This scaling pattern suggests the GPU becomes increasingly important as resolution rises.

At Medium settings, the scaling is similar but with a slightly different slope. 1080p Medium yields 182 FPS, 1440p Medium yields 125 FPS (31% drop), and 4K Medium yields 73 FPS (60% drop from 1080p). The High settings show 139 FPS at 1080p, 95 FPS at 1440p (32% drop), and 56 FPS at 4K (60% drop). Ultra settings produce 132 FPS at 1080p, 91 FPS at 1440p (31% drop), and 53 FPS at 4K (60% drop).

The consistent 28-32% frame rate drop from 1080p to 1440p across all settings indicates that the GPU is the primary scaling component. The pixel count increases by 78% from 1080p to 1440p, but frame rates drop by roughly 30%, which is less than the pixel increase would suggest. This implies that the CPU still has some influence at 1080p, limiting the GPU's potential. At 1080p Low, the 228 FPS average may be near the CPU's ability to feed the GPU, as the RX 9070 is capable of higher frame rates in less CPU-bound scenarios.

From 1440p to 4K, the frame rate drops are approximately 41% at Low (164 to 97 FPS), 42% at Medium (125 to 73 FPS), 41% at High (95 to 56 FPS), and 42% at Ultra (91 to 53 FPS). The 4K pixel count is 2.25 times that of 1440p, but frame rates drop by roughly 42%, which is proportionally less than the pixel increase. This indicates that the GPU is increasingly the limiting factor at higher resolutions, as its compute and memory bandwidth are being fully utilized.

The data shows a clear transition point. At 1080p, the CPU has more influence, as evidenced by the relatively small frame rate differences between Low (228 FPS) and Ultra (132 FPS) settings—a 42% spread. At 4K, the spread between Low (97 FPS) and Ultra (53 FPS) is 45%, but the absolute values are much lower. The limiting component shifts from CPU at 1080p to GPU at 4K, with the GPU becoming the dominant constraint as resolution increases.

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

At 1920x1080 resolution, the combo delivers the following average frame rates across settings:

• Low: 228 FPS average
• Medium: 182 FPS average, with a minimum of 155 FPS and maximum of 209 FPS
• High: 139 FPS average
• Ultra: 132 FPS average

The 1080p results show that the game is highly playable at all settings, with even Ultra settings exceeding 130 FPS. The Medium setting's frame time data (155-209 FPS range) indicates some variance, but the average of 182 FPS is smooth. The difference between High (139 FPS) and Ultra (132 FPS) is just 7 FPS, suggesting diminishing returns from High to Ultra at this resolution.

At 2560x1440 resolution, the frame rates are:

• Low: 164 FPS average
• Medium: 125 FPS average, with a minimum of 106 FPS and maximum of 144 FPS
• High: 95 FPS average
• Ultra: 91 FPS average

The 1440p results still exceed 90 FPS at all settings, making this resolution comfortable for high-refresh-rate displays. The gap between High (95 FPS) and Ultra (91 FPS) narrows to 4 FPS, indicating that Ultra settings are nearly free at this resolution. The Medium setting's frame time range of 106-144 FPS shows a 38 FPS spread, which could be noticeable on a 144 Hz monitor but remains within acceptable bounds.

At 3840x2160 resolution, the frame rates are:

• Low: 97 FPS average
• Medium: 73 FPS average, with a minimum of 62 FPS and maximum of 84 FPS
• High: 56 FPS average
• Ultra: 53 FPS average

The 4K results show a significant drop-off. Low settings maintain nearly 100 FPS, making 4K Low viable for competitive play. Medium settings drop to 73 FPS, which is still smooth for most players. High settings at 56 FPS are playable but start to show the GPU's limits. Ultra settings at 53 FPS are borderline for a stealth game, where frame rate consistency matters more than raw speed. The Medium setting's frame time range of 62-84 FPS (22 FPS spread) is tighter than at lower resolutions, indicating the GPU is more consistently loaded.

# Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target display and preference.

For 1080p displays, Ultra settings at 132 FPS average is the recommended configuration. The frame rate exceeds 130 FPS, which is smooth on most displays, and the visual fidelity benefits from the game's highest preset. The difference between High (139 FPS) and Ultra (132 FPS) is only 7 FPS, so the visual upgrade is essentially free. For players with 144 Hz monitors who prioritize frame rate, Medium settings at 182 FPS average provides a substantial frame rate boost with a 155 FPS minimum, ensuring the frame rate rarely dips below the refresh rate.

For 1440p displays, Ultra settings at 91 FPS average is recommended for visual quality. This frame rate is smooth for a stealth game, where precision and atmosphere matter more than competitive frame rates. If a higher refresh rate is preferred, Medium settings at 125 FPS average delivers a 34 FPS improvement over Ultra, with a 106 FPS minimum that stays above common 100 Hz refresh rates. The Medium preset's visual differences from Ultra are minor in Thief's dimly lit environments.

For 4K displays, Medium settings at 73 FPS average provides the best balance between visual quality and performance. The 62 FPS minimum ensures the frame rate stays above 60 FPS, which is the standard for console-like smoothness. Low settings at 97 FPS average is the better choice for players who prioritize frame rate consistency, as it nearly reaches 100 FPS and provides a 24 FPS improvement over Medium. High settings at 56 FPS and Ultra settings at 53 FPS are playable but risk dropping below 60 FPS, which may be noticeable in a game that relies on careful observation. The 4K Medium preset's frame time range of 62-84 FPS is the tightest of all measured configurations, indicating stable performance during gameplay.
