Thief

The AMD Ryzen 9 9900X3D paired with the NVIDIA GeForce RTX 3080 delivers a wide range of frame rates in Thief, from 228 FPS at 1080p Low to 54 FPS at 4K Ultra. This dataset, measured on real hardware, shows a clear resolution hierarchy and provides insight into how this CPU-GPU combination performs against the broader tested database. The data reveals that the RTX 3080 is the primary scaling factor as resolution increases, while the 12-core 9900X3D offers ample compute headroom.

Resolution Scaling

The measured average FPS for each resolution and preset is consistent across the board. At 3840×2160, the Low preset achieves 98 FPS, Medium 75 FPS, High 57 FPS, and Ultra 54 FPS. At 2560×1440, those same presets yield 167, 127, 97, and 92 FPS respectively. At 1920×1080, the numbers climb to 228, 185, 141, and 134 FPS.

The step from 1080p to 1440p reduces frame rates sharply. For High, 141 FPS becomes 97 FPS; for Ultra, 134 becomes 92; for Medium, 185 becomes 127; for Low, 228 becomes 167. The subsequent step to 2160p cuts these numbers roughly in half—High goes from 97 to 57, Ultra from 92 to 54, Medium from 127 to 75, and Low from 167 to 98. The consistent pattern across all preset levels indicates that the rendering workload increases nearly linearly with pixel count, which is a typical sign that the GPU is the dominant limit at higher resolutions.

At Medium preset the dataset also includes a minimum and maximum FPS frame cap: 63–86 at 4K, 108–146 at 1440p, and 157–213 at 1080p. These ranges offer additional insight into frame pacing. The minimum values stay well above typical VSync thresholds except at 4K, where the 63 FPS minimum is still above 60, but the average is 75. The fact that the 4K High average is 57 (short of 60) while Medium is 75 indicates that the GPU has enough headroom to handle the same pixel count with lower memory and shader requirements.

The data does not include separate CPU or memory timing measurements, but the relative FPS differences between presets at the same resolution are uniform. For example, at 1080p, the highest preset (Ultra) yields 134 FPS, while the lowest (Low) yields 228 FPS—a difference of nearly two times. At 4K, the spread is narrower: Ultra at 54, Low at 98. This narrowing at 4K is expected when the GPU becomes increasingly overwhelmed, leaving less room for preset changes to change the frame rate as drastically.

CPU Role

The AMD Ryzen 9 9900X3D is a 12-core, 24-thread processor based on Zen 5 architecture, with a base clock of 4.40 GHz and boost up to 5.50 GHz. It has a large L3 cache of 128 MB, a TDP of 120 W, and a DDR5 dual-channel memory interface. The processor is rated in the 91st percentile among all CPUs in the benchmark database, with an average benchmark score of 54,762.

In synthetic CPU tests, the 9900X3D posts a 3DMark single-thread score of 1,269 and a 16-thread score of 12,490. Its Cinebench R23 multi-core score is 47,737, and the single-thread score is 6,739. These numbers place the CPU well above typical desktop processors in both single- and multi-threaded workloads.

Looking at the nearest rivals, the 9900X3D is essentially even with the Intel Core Ultra 5 245KF (deltaPct -0.6), meaning it trails that chip by 0.6% in average benchmark score. It is ahead of the Intel Core Ultra 5 245K by 1.3% and the Intel Xeon 6505P by 2%. This shows that while the 9900X3D is at the top of the list, it does not have a decisive lead over its closest competition.

Given that Thief is a 2014 first-person stealth game, the importance of high single-thread strength is more critical than core count. The 9900X3D’s single-thread performance, as measured by passmark single thread (score 4,646) and Cinebench R20 single core (score 2,841), ensures that the game’s main simulation and logic threads will not stall the frame render pipeline. The common low average frame rates at lower resolutions, such as the 228 FPS at 1080p Low, indicate that the CPU is not the bottleneck—the engine is running as fast as the GPU allows at that setting.

Nonetheless, the CPU’s multi-threaded firepower (24 threads) is largely auxiliary in a game that likely uses only a few threads; the GPU is the decisive factor when moving to 4K. The data shows that even the lowest preset at 4K (98 FPS) is only 40% higher than the 4K High result (70 FPS? Actually 98 vs 57, that's 51.4 difference; 98/57=1.72). The CPU is not limiting the ability to push frame rates when the resolution is high.

GPU Role

The NVIDIA GeForce RTX 3080 is based on the Ampere GA102 chip, manufactured on an 8 nm process. It features 10 GB of GDDR6X memory on a 320-bit bus with a bandwidth of 760.3 GB/s. The GPU has 8,704 shading units, 272 texture mapping units, and 96 ROPs, along with 68 RT cores and 9th-gen tensor cores. The peak FP32 throughput is 29.77 TFLOPS, and the board TDP is 320 watts.

The GPU ranks in the 68th percentile of all GPUs, with an average benchmark score of 23,172. Its 3DMark Steel Nomad DX12 score is 4,407, and it shows a passMark G3D score of 25,086. The nearest rivals are all –0.3–0.4% faster in average GPU benchmark score: NVIDIA P106-100, AMD Radeon Pro Vega 16, AMD Radeon RX 6600M, and AMD Radeon R9 M290X. This indicates the RTX 3080 sits at the upper edge of mainstream GPUs, but it is not a top-tier card.

In Thief, the GPU footprint increases massively with resolution. At 1080p Medium, the average FPS is 185; at 1440p it is 127; at 4K it falls to 75. The GPU is clearly the resource that scales the resolution. The perfect linearity of these numbers (each step roughly halves the FPS) is a standard signature of GPU-bound rendering. The 10 GB VRAM is likely sufficient for the textures used at these preset levels, since no texture-related shudder is observed in the FPS data—the lowest presets lower memory pressure, but the FPS patterns remain similar.

The 4K Ultra preset yields an average of 54 FPS, which is below a 60 FPS target. Lowering to Medium brings it to 75 FPS, indicating that the GPU’s silicon is stressed less by the medium preset’s lighter shader load. The minimum FPS for 4K Medium is 63, which stays above 60, so a cap or V‑Sync can be achieved with this combination.

How This Combo Ranks

In Thief, the combination of the Ryzen 9 9900X3D and RTX 3080 is ranked the 697th best configured system out of 3,720 total in the database. That places it in the upper fifth of tested combos, indicating that the pair is capable of high settings at most resolutions, though it is not at the very top for 4K Ultra.

The CPU’s 91st percentile and GPU’s 68th percentile mean that the CPU is significantly stronger than the GPU in the synthetic aggregate. However, the combination overall sits at a moderate PC in this game: at 4K Ultra the system does not deliver a locked 60 FPS, but at 1080p and 1440p it exceeds the display refresh rates for most monitors. The mid-tier GPU means that performance scales with resolution well, but the ceiling might be moved by a stronger graphics card.

Settings Recommendations

Free from the guidance of experience, the measured FPS values suggest a precise target. If the goal is to maintain a consistent 60 FPS, the Medium preset at 4K meets that requirement (average 75 FPS, minimum 63) while providing headroom. The High preset at 4K
