Thief

The AMD Ryzen 5 5600GT and NVIDIA GeForce RTX 3080 form a system that is dominated by the GPU at higher resolutions in Thief, while the CPU shows enough headroom to let the RTX 3080 stretch its legs at 1080p. Measured results put this combo at rank 1081 out of 3720 tested combinations, placing it inside the top 29% of all tested setups. At 1080p Low the pair delivers an average of 164 FPS, while at 4K Ultra it drops to 54 FPS; the gap between the game's fastest and slowest measured configurations is 110 FPS. The data indicates a clear transition from CPU-focused throughput at low resolutions to a GPU-limited workload as pixel count rises, with the RTX 3080's Ampere architecture handling the majority of the load.

Resolution Scaling

The FPS results across resolutions reveal how this combo's performance changes as pixel count increases. At 1080p, the system produces high frame rates across all settings: 164 FPS on Low, 148 FPS on Medium, 134 FPS on High, and 132 FPS on Ultra. The spread between Low and Ultra at 1080p is only 32 FPS (164 vs 132), suggesting that the CPU is not being overwhelmed at those settings. Moving to 2560x1440, the same settings produce 145, 127, 97, and 92 FPS respectively. The gap between Low and Ultra at 1440p widens to 53 FPS (145 vs 92), though the decline from 1080p is roughly consistent across settings: about 11–12% for Low and Medium (164→145, 148→127), a 28% drop for High (134→97), and a 30% drop for Ultra (132→92). At the 4K resolution, the performance falls sharply. Medium averages 75 FPS, High 57 FPS, Ultra just 54 FPS, and Low reaches 98 FPS. The drop from 1440p to 4K is far more aggressive: 37% for Low (145→98), 41% for Medium (127→75), 41% for High (97→57), and 41% for Ultra (92→54).

These numbers point to a component that becomes the dominant limiter at higher pixel counts. The scaling pattern—where frame rate diminishes roughly in proportion to pixel count (1440p has ~1.78x pixels of 1080p, and 4K has ~2.25x of 1440p)—suggests a GPU-bound workload. If the CPU were the primary bottleneck, the FPS would not degrade so dramatically when only the rendering resolution changes. At 1080p, the CPU's 6 cores and 12 threads appear to keep up, as the lowest settings deliver over 160 FPS, but at 4K the RTX 3080's fill rate is the deciding factor. The uptick from 54 FPS on Ultra at 4K to 98 FPS on Low shows that the GPU has enough headroom to handle the geometry changes at lower image quality, but it cannot sustain high quality frame rates at 4K.

The scaling behavior also gives insight into what would happen if one part were replaced. Because the performance department at 4K is clearly on the shoulders of the RTX 3080, a user looking for higher 4K frame rates would need to lower settings or look at the GPU. Conversely, at 1080p, the CPU becomes more relevant, and the 5600GT’s single-thread and multi-thread scores—Geekbench single-core 1843 and multi-core 7986—show it has enough compute to feed the GPU without a major loss in frame output.

Q: How many tested combos does this setup rank above?

A: The 5600GT + RTX 3080 ranks 1081st out of 3720 tested combinations, meaning it beats 2639 combos (since 3720 - 1080 = 2639). That puts it in the top 29% of all tested combos.

How This Combo Ranks

Among the 3720 tested CPU and GPU combinations for Thief, this specific pairing places 1081st. That ranking means it outperforms 2639 of the other combos, landing in the upper 71st percentile of configurations. To contextualize rank, consider that the top-ranked combos likely pair the fastest CPUs with the strongest GPUs; this system uses a mid-range CPU (Ryzen 5 5600GT with a 74th overall CPU percentile) and a high-end GPU (RTX 3080 with a 68th overall GPU percentile). The offset between the CPU and GPU rankings might be a limiting factor: the CPU’s performance is slightly lower than the GPU’s in relative terms. However, the combo rank mainly reflects how the two work together in Thief specifically.

The RS combination’s strengths align with its component separation. At 1080p, the CPU does not hold back the GPU, as evidenced by the Low and Medium averages of 164 and 148 FPS. The 5600GT’s 6 cores and 12 threads, with a boost clock of 4.60 GHz, provide enough instruction throughput to keep frame rates up. At 4K, the RTX 3080’s bandwidth and 10 GB GDDR6X memory become the performance constraint, matching the GPU’s 68th percentile. The overall ranking thus reflects the system’s ability to adapt heavily from 1080p (high CPU usage) to 4K (high GPU usage), but it falls short of combos that use the more powerful GPUs at 4K.

Measured FPS Breakdown

The fitted results for all setups are as follows:

| Resolution | Settings | Average FPS | Min / Max FPS |

|------------|----------|----|-----------------|

| 1920x1080 | Low | 164| - |

| 1920x1080 | Medium | 148| 126 / 171 |

| 1920x1080 | High | 134| - |

| 1920x1080 | Ultra | 132| - |

| 2560x1440 | Low | 145| - |

| 2560x1440 | Medium | 127| 108 / 146 |

| 2560x1440 | High | 97| - |

| 2560x1440 | Ultra | 92| - |

| 3840x2160 | Low | 98| - |

| 3840x2160 | Medium | 75| 63 / 86 |

| 3840x2160 | High | 57| - |

| 3840x2160 | Ultra | 54| - |

At 1080p, the difference between Ultra and Low is only 32 FPS (132 vs 164), while at 1440p the difference grows to 53 FPS (97 to 145). The discrepancy highlights how strongly the GPU threads change with resolution. The Medium preset shows the largest variance: at 1080p, the maximum of 171 FPS and minimum of 126 FPS yield a 45 FPS swing; at 1440p the swing is 38 FPS (108–146); and at 4Kp the spread is 23 FPS (63–86). These ranges give a sense of the engine's internals, but the average provides a stable metric for feature comparison.

The gap between Low and High settings also tells a story: At 1080p, dropping from High to Low adds 30 FPS (134 to 164), a 22% boost. At 1440p the same change yields 48 FPS (97 to 145), which is a 49% increase. At 4Kp, Low over Chapter adds 41 FPS (57 to 98), a 72% increase. This same scaling shows that quality floors loosen the load on the GPU, particularly at higher resolutions.

GPU Role

The RTX 3080 is the dominant component in this combination. It uses the GA102 chip (Ampere architecture) on an 8 nm process with 28,300 million transistors and a die size of 628 mm². Its memory subsides consist of 10 GB of GDDR6X on a 320-bit bus with a bandwidth of 760.3 GB/s. The GPU’s base clock is 1440 MHz and boost to 1710 MHz, and it has 8704 shading units, 272 TMUs, and 96 ROPs outside the suite of 68 RT-cores and 272 tensor cores. These raw resources are applied to Thief’s workloads: The pixel rate yields 164.2 GPixel/s, and the texture fill rate is 465.1 GTexel/s, which helps to explain the strong performance at 1440p and the clearing drop to 4Kp.

In the benchmark database, the RTX 3080 achieves an average score of 23172 and sits at the 68th percentile among all GPUs. Its closest rivals in the database are the NVIDIA P106-100 with 23249 points (0.3% higher), AMD Radeon Pro Vega 16 at 23250 (0.3% higher), AMD Radeon RX 6600M at 23273 (0.4% higher), and AMD Radeon R9 M290X at 23276 (0.4% higher). Thus, it is effectively tied with those parts. In Thief, the data reveals that at 4Kp Ultra the card can only deliver 54 FPS average, which is a technical limitation. The enormous memory bandwidth (up to 60 GB/s) does not offset the raw fill-rate need at the Ultra preset. If you wish to get the highest quality settings at 4K, the RTX 3080 will fall to sub-60 approximations; for a more fluid experience, the user may have to select High or Medium.

CPU Role

The AMD Ryzen 5 5600GT is a 6-core, 12-thread processor based on Zen 3 (Cezanne) running on the AM4 socket. It has a base clock of 3.60 GHz and a Max boost clock of 4.60 GHz, with 16 MB of L3 cache and 64 KB L1 per core as well as 512 KB L2 per core. Its TDP is 65 W, and it supports DDR4-3200 in a dual-channel layout, giving 51.2 GB/s of memory bandwidth. The chip has a pass average benchmark score of 20733, and its percentile over all CPUs is 74th. That benchmark places it 0.3% below the nearby Intel Core i5-12490F (20802), and 0.4% below the Xeon 6325P (20821), Core Ultra 5 125U (20826), and EPYC 7J13 (20845). Similarly, its single-thread and multi-thread division is balanced.

In the measured game results, the CPU's role is most visible in the watch at discrete steps: The difference in FPS between Low and Ultra at 1080p is only 32 FPS (164 vs 132) and at 1440p is 53 FPS (145 vs 92). If the processor were the bottleneck, the gap would be smaller at the same settings across resolutions; however the gap broadens with resolution, which reinforces that the GPU is the primary constraint. The CPU still shows its worth in the fact that at 1080p Low, the system can reach 164 FPS, which is a high score for a six-core part. Encoding the GPU uses the RTX. The lack of severe CPU contribution is probably due to the game's age (released in 2014) and its light allocation of tasks to the six cores. In the end, the CPU provides enough string money to let the RTX 3080 have run at 1080p and 1440p, but does not dominate the system elsewhere.
