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

The measured frame rates across resolutions reveal a classic pattern of GPU-bound scaling. At 1080p Ultra, this combo delivers 113.5 FPS average. Moving to 1440p Ultra drops that to 81.1 FPS, a 28.5% reduction. Pushing further to 4K Ultra yields 45.8 FPS, which is 59.6% below the 1080p figure. The steepness of this decline indicates that the NVIDIA GeForce RTX 3070 becomes the primary constraint as pixel count rises.

Low settings tell a similar story but with a different slope. At 1080p Low, the system reaches 166.9 FPS. At 1440p Low, it hits 145.6 FPS — only a 12.8% drop. At 4K Low, it still manages 86.8 FPS, a 48% reduction from 1080p. The relatively modest 1440p drop at Low settings suggests that at lower visual complexity, the AMD Ryzen 5 5600GT's six cores can keep feeding frames without bottlenecking, but the GPU still dominates the 4K transition.

The gap between Low and Ultra narrows as resolution rises. At 1080p, Ultra is 46.9% slower than Low (113.5 vs 166.9 FPS). At 4K, Ultra is 47.2% slower than Low (45.8 vs 86.8 FPS). This consistency implies that the rendering workload scales almost purely with resolution, not with settings complexity — a hallmark of a game that is heavily pixel-bound at higher resolutions. The RTX 3070's 8 GB GDDR6 memory and 448.0 GB/s bandwidth appear sufficient for the memory footprint, but raw throughput becomes the limiting factor at 4K.

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

The AMD Ryzen 5 5600GT brings six cores and twelve threads, running at a base clock of 3.60 GHz and boosting to 4.60 GHz. This Zen 3 architecture chip, built on a 7 nm process with TSMC, shows strong single-thread performance in synthetic tests — a 3dmark single-thread score of 913 and a Cinebench R23 single-core result of 2438. For a 2014 stealth title, single-thread performance often matters more than raw core counts, and the data supports that interpretation.

At 1080p Low, the system produces 166.9 FPS. This is a high frame rate that demands substantial CPU input, yet the processor still delivers. The CPU's PassMark single-thread score of 3348 and its percentile ranking of 78 versus all CPUs suggest it sits comfortably above average. The 3dmark 2-thread score of 1794 hints that lightly-threaded workloads — typical for older game engines — are handled efficiently.

Looking at multi-threaded potential, the CPU posts a Cinebench R23 multi-core score of 17272 and a PassMark multithread score of 20325. These numbers indicate headroom for modern titles, but Thief's age means it likely doesn't tax all twelve threads. The nearest rival comparison shows the 5600GT essentially tied with the Intel Core i7-10700 (deltaPct 0%) and the AMD Ryzen 5 5600X (deltaPct 0.3% faster). The data implies that CPU differences would not be the deciding factor in this game's frame rates at high resolutions.

The 16 MB L3 cache and dual-channel DDR4 memory support (51.2 GB/s bandwidth) provide adequate memory bandwidth for feeding the RTX 3070. At 4K Ultra, where the GPU is clearly the bottleneck, the CPU is unlikely to be the limiting component. The benchmark results indicate the 5600GT can sustain high frame rates without becoming a drag, even when paired with a powerful GPU.

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

The NVIDIA GeForce RTX 3070 is built on the GA104 chip using Samsung's 8 nm process, with 17,400 million transistors packed into a 392 mm² die. Its base clock of 1500 MHz and boost clock of 1725 MHz, combined with 5888 shading units, deliver a measured FP32 throughput of 20.31 TFLOPS. These specifications translate into strong rasterization performance for a game like Thief, which launched before ray tracing was a consideration.

The 8 GB GDDR6 memory on a 256-bit bus provides 448.0 GB/s of bandwidth. At 4K Ultra, the average frame rate falls to 45.8 FPS — playable but not smooth. The 4K High preset gives 49.9 FPS, suggesting that dropping from Ultra to High yields only a marginal 8.2% improvement. This small gain implies that the Ultra preset's extra effects are not the primary cost; rather, the resolution itself is the challenge.

The RTX 3070's PassMark G3D score of 22214 and its 72nd percentile ranking among all GPUs place it as a capable mid-to-high-end card. Its nearest rivals include the AMD Radeon RX 6600 XT (0.9% slower) and the NVIDIA GeForce GTX 980 Ti (1% slower). These comparisons show that the RTX 3070 holds a slight edge over those cards, though the deltas are small. For a 2014 game, this GPU is far more powerful than what was available at launch, which explains why 1080p and 1440p frame rates are so high.

The GPU's memory bandwidth becomes the likely constraint at 4K. The 256-bit bus and 8 GB capacity are adequate for 1440p Ultra (81.1 FPS) but struggle to maintain 60 FPS at 4K Ultra. The data shows a clear threshold: 1440p High at 85.2 FPS is smooth, while 4K Medium at 61.9 FPS just barely crosses the 60 FPS line. This suggests that for 4K play, Medium settings are the practical ceiling for this GPU in Thief.

How This Combo Ranks

The AMD Ryzen 5 5600GT and NVIDIA GeForce RTX 3070 combination ranks 665th out of 1642 tested combos for Thief, placing it in the 59th percentile of the database. This is a strong showing for a game released in 2014, given that the RTX 3070 is a modern card with a 72nd percentile GPU ranking. The CPU's 78th percentile ranking among all CPUs further supports that this combo sits well above the median.

Comparing to the CPU's nearest rivals, the 5600GT is essentially tied with the Intel Core i7-10700 (0% delta) and just 0.3% slower than the AMD Ryzen 5 5600X. This means that swapping the processor for a similar-tier Intel or AMD chip would yield negligible changes in Thief's frame rates — the GPU dominates the outcome. The GPU's nearest rival, the AMD Radeon RX 6600 XT, is only 0.9% slower, suggesting that the RTX 3070's advantage is narrow but real.

The rank of 665 out of 1642 indicates that roughly 60% of tested combos perform worse in Thief. This is a comfortable position for 1440p gaming, where the combo achieves 81.1 FPS at Ultra and 110.6 FPS at Medium. For 4K, the rank reflects the GPU's limitations at higher pixel counts, but it still outperforms many older or weaker combos. The data implies that this pairing is well-matched for 1080p and 1440p, with 4K playable only at lower settings.

Settings Recommendations

For the best balance of visual quality and frame rate, the measured data points to 1440p High as the optimal preset. At 85.2 FPS average, this setting provides smooth gameplay while retaining most visual features. Dropping to 1440p Medium raises the average to 110.6 FPS, a 29.8% improvement, which may be preferable for players who prioritize high refresh rates over subtle visual differences.

At 1080p, the High preset at 119.8 FPS is excellent, but Ultra at 113.5 FPS is nearly as fast — a 5.3% difference. Given that Ultra typically adds effects like higher shadow quality and tessellation, the 1080p Ultra setting is a viable choice for those with 144 Hz monitors, as it stays above 100 FPS. At 4K, the Medium preset at 61.9 FPS is the only setting that breaks the 60 FPS barrier; High at 49.9 FPS and Ultra at 45.8 FPS are both below that threshold.

The data suggests a clear strategy: for 1080p, use Ultra or High; for 1440p, use High as the default, with Medium for higher refresh rates; for 4K, use Medium for playability, accepting that Ultra is not viable. The Low preset at any resolution provides a large frame rate boost — 166.9 FPS at 1080p, 145.6 FPS at 1440p, and 86.8 FPS at 4K — but sacrifices visual fidelity for competitive or high-refresh play.
