Thief

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

The AMD Ryzen 9 9900X is a 12-core, 24-thread processor built on the Zen 5 architecture (Granite Ridge). Its base clock sits at 4.40 GHz, while the boost clock reaches 5.60 GHz. The 80 KB L1 cache per core, 1 MB L2 per core, and 64 MB shared L3 cache provide substantial on-die storage for game data. The CPU scores in the 94th percentile among all processors, with an average benchmark score of 54450.

In Thief, a stealth title from 2014, the CPU's role is less about raw multi-threaded throughput and more about single-thread responsiveness. The 3dmark_single_thread score of 1286 and the passmark_single_thread score of 4672 indicate strong per-core performance. This matters because Thief's game logic, AI pathfinding, and physics calculations often rely on fewer threads. The 3dmark_2_threads score of 2519 and 3dmark_4_threads score of 4886 show that even at low thread counts, the CPU scales effectively.

The Ryzen 9 9900X sits within a tight competitive band. Compared to the AMD Ryzen 9 9900X3D, it trails by 0.4% in average score. It outperforms the Intel Core i7-14700F by 0.7% and trails the Intel Core Ultra 5 245K by 1.5% and the Core Ultra 5 245KF by 1.8%. These deltas are small, suggesting that in Thief, the CPU is unlikely to be the primary bottleneck at most settings. The data shows that even at 1080p Low, where the CPU typically has the most influence, the system achieves 231.3 FPS — a figure that points to no significant CPU limitation.

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

The NVIDIA GeForce RTX 4080 SUPER uses the AD103 chip on the Ada Lovelace architecture. It features 16 GB of GDDR6X memory on a 256-bit bus, yielding a bandwidth of 736.3 GB/s. The base clock is 2295 MHz, boosting to 2550 MHz, with memory running at 1438 MHz (23 Gbps effective). The GPU has 10240 shading units, 320 TMUs, and 112 ROPs.

For Thief, the GPU's pixel rate of 285.6 GPixel/s and texture rate of 816.0 GTexel/s are the key specifications. The game's environments feature dense geometry and heavy texture work, particularly in its dimly lit corridors and outdoor city sections. The 16 GB VRAM capacity is more than sufficient for Thief's texture sets, even at Ultra settings, so memory capacity is not a limiting factor in the measured results.

The RTX 4080 SUPER ranks in the 88th percentile among all GPUs with an average benchmark score of 53610. Its nearest rivals show a close grouping: the AMD Radeon RX 6900 XT trails by 0.2%, the Radeon Pro W6600M trails by 0.4%, the Radeon RX 7700S trails by 2.1%, and the RTX 5070 Ti trails by 2.9%. This suggests the GPU is well-positioned relative to its peers. In Thief, the GPU's influence becomes more pronounced as resolution increases, particularly at 4K where the rendering load grows substantially.

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

Examining the measured FPS across resolutions reveals a clear pattern of GPU scaling. At High settings, the system delivers 186.2 FPS at 1080p, 127 FPS at 1440p, and 74.3 FPS at 4K. The drop from 1080p to 1440p is 59.2 FPS (a 31.8% reduction), while the drop from 1440p to 4K is 52.7 FPS (a 41.5% reduction). This accelerating decline with resolution is characteristic of GPU-bound scenarios.

At Low settings, the trend is similar but with higher absolute numbers: 231.3 FPS at 1080p, 201.9 FPS at 1440p, and 129.8 FPS at 4K. The 1080p to 1440p drop is 29.4 FPS (12.7%), while the 1440p to 4K drop is 72.1 FPS (35.7%). The relatively modest decline from 1080p to 1440p at Low settings suggests the CPU can keep up at lower resolutions, but the 4K penalty reveals the GPU's workload increasing substantially.

Medium settings show 209.3 FPS at 1080p, 167.4 FPS at 1440p, and 97.2 FPS at 4K. Ultra settings produce 176.1 FPS at 1080p, 119.4 FPS at 1440p, and 73.5 FPS at 4K. Across all settings, the 4K figures cluster between 73.5 and 129.8 FPS, while 1080p figures range from 176.1 to 231.3 FPS. This wide spread indicates that at 1080p, the CPU and GPU are both contributing, but at 4K, the GPU becomes the dominant constraint. The data suggests that for competitive play at high refresh rates, 1080p or 1440p are the viable resolutions, while 4K targets a smooth 60+ FPS experience at most settings.

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

The measured FPS data provides clear guidance for settings selection. At 4K, the High preset delivers 74.3 FPS, while Ultra delivers 73.5 FPS — a difference of only 0.8 FPS. This negligible gap means Ultra costs almost nothing in performance at 4K, making it the preferred choice for visual fidelity. Medium at 4K produces 97.2 FPS, which is 22.9 FPS higher than High, but the visual trade-off may not justify the gain for users with 60 Hz displays.

At 1440p, all presets exceed 119 FPS. Ultra delivers 119.4 FPS, High delivers 127 FPS, Medium delivers 167.4 FPS, and Low delivers 201.9 FPS. For users with 144 Hz monitors, the High preset at 127 FPS provides a smooth experience close to the refresh ceiling. However, the jump from High to Medium (40.4 FPS) is substantial, suggesting that Medium at 1440p offers a strong balance for high-refresh-rate displays.

At 1080p, every preset exceeds 176 FPS. Ultra delivers 176.1 FPS, High delivers 186.2 FPS, Medium delivers 209.3 FPS, and Low delivers 231.3 FPS. For 240 Hz displays, Low or Medium are the only presets that approach the refresh ceiling. The data indicates that Ultra at 1080p is still very playable, but for competitive play where frame rate matters most, Medium or Low provide the headroom.

The overall recommendation based on the measured rows: at 4K, use Ultra for the best visual quality with minimal performance cost. At 1440p, High provides an excellent balance, with Medium as an option for higher refresh rates. At 1080p, Medium offers the best mix of visual quality and frame rate headroom.
