Thief

Thief, a 2014 stealth title, shows distinct performance scaling on the AMD Ryzen 5 4600G and NVIDIA GeForce RTX 3080 combination. The CPU, with its 6 cores and 12 threads, operates at a base clock of 3.70 GHz and a boost clock of 4.20 GHz, placing it in the 75th percentile of all CPUs. The GPU, an Ampere-architecture RTX 3080, sits in the 80th percentile of all GPUs. The measured frame rates across resolutions and settings reveal a system where the CPU provides a solid foundation, while the GPU's raw power becomes the defining factor at higher resolutions and quality presets.

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

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor based on the Zen 2 architecture, built on a 7 nm process. Its boost clock of 4.20 GHz is the primary driver for single-threaded performance, which is critical for a game like Thief that relies on game logic and AI. The processor's benchmark scores reflect a balanced profile: a Cinebench R23 multi-core score of 13593 and a single-core score of 1919. In the broader context, the 4600G's average benchmark score of 17489 places it within 0.1% of the Intel Core i5-12450H and about 1% behind the Intel Core i3-13100F, indicating its competitive standing among peers for CPU-bound tasks.

For Thief, the CPU's role appears most significant at lower resolutions and settings, where the GPU is not the limiting factor. At 1080p Low, the system achieves 128.5 FPS, and at 1080p Ultra, it drops to 105.6 FPS. The relatively small 22.9 FPS gap between Low and Ultra at 1080p suggests that the CPU is handling the frame-time overhead well, even when the graphical load increases. The processor's multi-threaded capability, evidenced by a 3DMark max-threads score of 4889, likely prevents bottlenecking when the game's engine spawns multiple AI characters or processes complex stealth interactions. The 4600G's 8 MB of shared L3 cache is adequate for this title's data demands, as the game predates the more cache-hungry titles of later years.

At 4K, however, the CPU's influence wanes. The difference between 4K Low (93.7 FPS) and 4K Ultra (55.8 FPS) is 37.9 FPS, a much larger spread than at 1080p. This indicates that at higher resolutions, the GPU is becoming the dominant constraint, with the CPU having ample headroom to feed frames. The data shows that the Ryzen 5 4600G is not a bottleneck at 4K Ultra, as the frame rate is still respectable at 55.8 FPS, but the scaling from Low to Ultra at 4K is more pronounced, pointing to the GPU's workload increasing faster than the CPU's ability to compensate.

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

The NVIDIA GeForce RTX 3080 is a high-end Ampere-generation card with 10 GB of GDDR6X memory and a 320-bit memory bus. Its boost clock of 1710 MHz and memory clock of 1188 MHz (19 Gbps effective) produce a memory bandwidth of 760.3 GB/s. This bandwidth is crucial for Thief's detailed textures and shadow rendering, especially at high resolutions. The GPU's PassMark G3D score of 25086 and a 3DMark Steel Nomad DX12 score of 4407 place it in the 80th percentile of all GPUs, with its nearest rival being the AMD Radeon RX 7900 GRE, which scores 0.9% higher.

The RTX 3080's 10 GB VRAM is sufficient for Thief at all tested settings, as the game's maximum resolution of 3840x2160 does not appear to exceed this capacity, even at Ultra settings. The GPU's raw compute power, with 8704 shading units and 29.77 TFLOPS FP32 performance, is more than enough for a game from 2014. This is evident in the 4K Ultra result of 55.8 FPS, which is well above playable thresholds. The GPU's role is most apparent when comparing settings at the same resolution. At 1440p, the RTX 3080 delivers 94.2 FPS on Ultra, which is only 18.2 FPS less than the 112.4 FPS on Low, showing that the card can handle the increased shader and texture work without a dramatic performance penalty.

The RTX 3080's performance relative to its peers is consistent with its high-end positioning. Its average benchmark score of 35787 is nearly identical to the AMD Radeon Pro Duo (35860, 0.2% higher) and the AMD Radeon 880M (35646, 0.4% lower), confirming that it sits at the top tier of available graphics solutions. For Thief, this means that the GPU will rarely be the cause of sub-60 FPS frame rates, except at the most demanding 4K Ultra preset, where it still manages to deliver a smooth experience.

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

The measured FPS data across resolutions provides a clear picture of system scaling. At High settings, the transition from 1080p (105 FPS) to 1440p (94 FPS) represents a 10.5% drop, while the jump from 1440p to 4K (54.8 FPS) is a substantial 41.7% drop. This non-linear scaling is a classic indicator of a GPU-bound scenario at 4K, where the pixel count quadruples from 1080p to 4K, putting enormous pressure on the render pipeline.

For Low settings, the scaling is less severe: 128.5 FPS at 1080p drops to 112.4 FPS at 1440p (a 12.5% decrease), and then to 93.7 FPS at 4K (a 16.6% decrease from 1440p). This suggests that at Low settings, the CPU is more involved in determining the frame rate, as the GPU has spare capacity. The fact that 4K Low is still above 90 FPS demonstrates that the RTX 3080 can brute-force this older title, and the CPU's 6 cores are adequate to keep up with the game's logic.

The Medium and Ultra presets show similar patterns to High, with 4K being the most demanding. At Medium, 1080p (115.1 FPS) falls to 102.8 FPS at 1440p (a 10.7% drop) and then to 74.7 FPS at 4K (a 27.3% drop from 1440p). At Ultra, the 1080p to 1440p drop is 10.8% (105.6 to 94.2 FPS), and the 1440p to 4K drop is 40.8% (94.2 to 55.8 FPS). The consistent pattern of a larger drop between 1440p and 4K across all presets confirms that the GPU is the limiting component at 4K, while at 1080p and 1440p, the system is more balanced, with the CPU and GPU sharing the workload.

Settings Recommendations

For the best experience measured, the 1440p High preset stands out as the optimal balance. At 2560x1440 with High settings, the system produces 94 FPS, which is 9.3% higher than the 4K High result of 54.8 FPS, while offering a significant visual improvement over the 1440p Low preset's 112.4 FPS. The 1440p Medium setting provides 102.8 FPS, which is 8.8 FPS more than High, but the visual difference between Medium and High is often substantial, making High the preferred choice for image quality.

At 1080p, the Ultra preset delivers 105.6 FPS, which is only 0.6 FPS more than the 1440p High result. This indicates that the system has enough headroom to run at a higher resolution without sacrificing frame rate, making 1080p less attractive unless the user has a 1080p monitor. For users with a 4K display, the High preset (54.8 FPS) is the highest playable option, but it comes close to the 60 FPS threshold. The 4K Medium preset (74.7 FPS) is also viable, providing a 19.9 FPS buffer over High, which might be preferable for smoother motion.

The data suggests that the Ultra preset offers diminishing returns over High across all resolutions. At 1440p, Ultra (94.2 FPS) is almost identical to High (94 FPS), differing by only 0.2 FPS. At 1080p, the difference is 0.6 FPS (105.6 vs 105). Therefore, selecting High over Ultra yields nearly the same performance with potentially better stability, based on the measured averages.

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

At 1920x1080, the system delivers its highest frame rates across all settings. The Low preset achieves 128.5 FPS, followed by Medium at 115.1 FPS, Ultra at 105.6 FPS, and High at 105 FPS. The spread from Low to Ultra is 23.5 FPS, with Medium, High, and Ultra all clustering within 10 FPS of each other, indicating that the CPU is the limiting factor at this resolution.

Moving to 2560x1440, the frame rates compress somewhat. Low settings produce 112.4 FPS, Medium 102.8 FPS, High 94 FPS, and Ultra 94.2 FPS. The gap between Low and Ultra widens to 18.2 FPS, but High and Ultra are effectively tied, with a difference of only 0.2 FPS. This suggests that at 1440p, the GPU begins to take on more work, but the CPU still has enough headroom to keep frames high.

At 3840x2160, the GPU becomes the dominant factor. The Low preset still delivers a smooth 93.7 FPS, but Medium drops to 74.7 FPS, Ultra to 55.8 FPS, and High to 54.8 FPS. The difference between Low and Ultra is 37.9 FPS, nearly double the spread seen at 1080p. Notably, the High and Ultra presets are nearly identical at 4K, with a difference of just 1 FPS, suggesting that the Ultra preset's additional effects are not heavily taxing the GPU compared to High. The system's overall rank in Thief is 795 out of 1642 tested combinations, placing it in the upper half of all configurations.
