Thief

Resolution Scaling

The measured frame rates across resolutions reveal a classic GPU-bound scaling pattern, though the curve is steeper than typical for a 2014 title. At 1080p High settings, the combo delivers 132.1 FPS average. Moving to 1440p High drops that to 111.6 FPS, a reduction of roughly 15.5%. The jump to 4K High lands at 64.8 FPS, which represents a 41.9% decline from the 1440p figure and a 50.9% drop from 1080p.

This scaling behavior indicates that the GeForce RTX 5070 is the primary limiting factor as resolution climbs, rather than the Ryzen 5 5600. The gap between 1440p and 4K is disproportionately large—more than double the percentage loss seen between 1080p and 1440p. That nonlinearity suggests the GPU's 12 GB GDDR7 memory and 192-bit bus are being saturated at 4K, particularly with the game's High preset which includes demanding texture work.

Looking at the Low preset, the scaling is flatter. At 1080p Low, the system hits 159.1 FPS. At 1440p Low, it maintains 142.5 FPS, a modest 10.4% reduction. At 4K Low, the frame rate falls to 113 FPS, which is still a 20.7% drop from 1440p but remains highly playable. The less demanding settings reduce pressure on the GPU's shading units and memory bandwidth, allowing the CPU to keep feeding frames more consistently.

The Medium preset sits predictably between Low and High. From 1080p Medium at 148 FPS to 1440p Medium at 128.1 FPS, the loss is 13.4%. The 4K Medium figure of 87.1 FPS is a 32% reduction from 1440p Medium. Interestingly, the Ultra preset shows the smallest relative drop between 1440p and 4K: from 104.9 FPS to 60.4 FPS, a 42.4% decline. This suggests Ultra settings introduce effects that scale with pixel count in ways that compress the performance envelope.

The data indicates that for this title, 1440p is the sweet spot for the combo. The 4K High result of 64.8 FPS is playable but barely clears the 60 FPS threshold, while 4K Ultra at 60.4 FPS sits right at the edge. Players targeting 4K will need to drop to Medium or Low settings to maintain comfortable headroom, whereas 1440p Ultra at 104.9 FPS offers both visual fidelity and smooth motion.

CPU Role

The AMD Ryzen 5 5600 brings six cores and twelve threads to the pairing, built on the Zen 3 architecture with a 3.50 GHz base clock and 4.40 GHz boost clock. Its 32 MB shared L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth provide adequate feeding for the GPU in this stealth title.

Thief, released in 2014, was designed for the multi-core era but does not scale aggressively beyond four to six threads. The CPU's 3DMark scores reflect a balanced profile: 882 in single-thread, 1,737 in 2-thread, 3,313 in 4-thread, and 4,798 in 8-thread tests. The max-thread score of 5,659 shows only a 17.9% improvement over the 8-thread result, indicating diminishing returns beyond eight threads—a pattern consistent with this game's engine.

The Cinebench R23 results reinforce this: 2,584 single-core and 18,309 multi-core. The single-core performance is what matters most for Thief's main thread, and the 4.40 GHz boost clock ensures that the CPU can keep pace with the GPU's frame generation at lower resolutions. The Passmark single-thread score of 3,256 places the chip well above average for gaming workloads.

However, the benchmark data suggests the CPU is not the bottleneck in most scenarios tested. At 1080p Low, the system reaches 159.1 FPS, which is near the practical ceiling for many game engines of this era. The fact that 1440p Low still holds 142.5 FPS indicates the CPU has headroom to spare. Only at 4K Ultra, where the GPU is clearly strained at 60.4 FPS, does the CPU role diminish further.

The Ryzen 5 5600's 65 W TDP and 7 nm process node from TSMC make it an efficient partner. Its nearest rivals in average benchmark score include the Intel Xeon D-1746TER at 21,635 (0.6% lower) and the AMD EPYC 9554P at 21,899 (0.6% higher). The chip's 79th percentile ranking among all CPUs underscores that it is a solid mid-range performer, well suited to pairing with a high-end GPU in a game like Thief where CPU demands are moderate.

GPU Role

The NVIDIA GeForce RTX 5070 is the dominant component in this pairing, and the measured frame rates reflect its capabilities. The GPU features 12 GB of GDDR7 memory on a 192-bit bus, delivering 672.0 GB/s of bandwidth. Its base clock of 2325 MHz and boost clock of 2512 MHz drive 6,144 shading units, 192 TMUs, and 80 ROPs.

The memory configuration is particularly relevant for Thief's 4K performance. The 12 GB capacity is sufficient for the game's textures at 4K, but the 192-bit bus width imposes bandwidth constraints. The 3DMark Steel Nomad DX12 score of 5,077 and Passmark G3D score of 29,137 place the GPU in the 83rd percentile among all GPUs. Its nearest rivals in average benchmark score include the NVIDIA GeForce RTX 3090 at 41,441 (0.6% lower) and the AMD Radeon Pro 5300 at 41,610 (0.2% lower).

The GPU's compute capabilities—30.87 TFLOPS FP32 and 201.0 GPixel/s pixel rate—are more than adequate for a 2014 title. The RTX 5070's architecture supports DirectX 12 Ultimate, Vulkan 1.4, and OpenGL 4.6, ensuring full compatibility with Thief's rendering paths. The 48 RT cores and 192 tensor cores are largely irrelevant for this game, as it predates ray tracing, but they do not interfere with performance.

The Passmark scores show interesting characteristics: DirectX 9 at 320, DirectX 10 at 180, DirectX 11 at 277, and DirectX 12 at 108. Thief uses DirectX 11, and the GPU's strong showing in that API (277) aligns with the measured frame rates. The lower DirectX 12 score suggests the GPU is optimized for older APIs, which benefits this title.

The GPU's 250 W TDP and dual-slot design require a 600 W suggested PSU. The 5 nm process node from TSMC with 31,100 million transistors on a 263 mm² die indicates a dense, efficient design. The 672.0 GB/s bandwidth is the key specification for 4K performance, and the scaling data shows it becomes the limiting factor at that resolution.

Measured FPS Breakdown

At 1080p, the combo delivers its highest frame rates across all settings. Low preset achieves 159.1 FPS average, Medium reaches 148 FPS, High hits 132.1 FPS, and Ultra manages 127.4 FPS. The spread from Low to Ultra is 31.7 FPS, representing a 19.9% performance penalty for maximum visual quality. This indicates that even at Ultra, the system has substantial headroom above the 60 FPS threshold.

At 1440p, the frame rates remain strong but show increased sensitivity to settings. Low preset maintains 142.5 FPS, which is only 10.4% below the 1080p Low figure. Medium drops to 128.1 FPS, High falls to 111.6 FPS, and Ultra sits at 104.9 FPS. The Low-to-Ultra spread widens to 37.6 FPS, a 26.4% penalty. The 1440p Ultra result of 104.9 FPS is still comfortably above 100 FPS, making this resolution ideal for high-refresh-rate displays.

At 4K, the performance profile changes dramatically. Low preset delivers 113 FPS, which is the only 4K setting that clears the 100 FPS mark. Medium drops to 87.1 FPS, High falls to 64.8 FPS, and Ultra bottoms out at 60.4 FPS. The Low-to-Ultra spread narrows to 52.6 FPS in absolute terms but represents a 46.5% penalty, showing that the GPU's bandwidth limitations are most pronounced at this resolution.

The transition from 1080p to 4K at each setting tells a clear story. Low loses 46.1 FPS (29%), Medium loses 60.9 FPS (41.1%), High loses 67.3 FPS (50.9%), and Ultra loses 67 FPS (52.6%). The settings with higher visual fidelity suffer proportionally more from the resolution increase, confirming that the GPU's memory subsystem is the bottleneck at 4K.

For players with 1080p or 1440p displays, the Ultra preset is entirely viable. Even at 4K, the Medium preset at 87.1 FPS offers a good balance, while High and Ultra require a tolerance for frame rates in the 60-65 FPS range. The data shows a system that is overqualified for 1080p, well-suited for 1440p, and adequate for 4K with settings adjustments.

How This Combo Ranks

The AMD Ryzen 5 5600 + NVIDIA GeForce RTX 5070 combination ranks 423rd out of 1,642 tested combos in Thief, placing it in the top 25.8% of all configurations tested. This is a strong showing for a mid-range CPU paired with a high-end GPU, and the ranking reflects the GPU's dominance in this workload.

The ranking position is somewhat surprising given the GPU's 83rd percentile standing among all GPUs. The 423rd rank out of 1,642 suggests that many higher-tier CPU+GPU combinations—particularly those with more powerful CPUs—achieve higher frame rates in this title. However, the measured data indicates that the CPU is not the limiting factor in most scenarios, so the rank likely reflects the GPU's absolute performance ceiling rather than any pairing inefficiency.

Compared to the GPU's nearest rivals in average benchmark score, the RTX 5070 sits close to the RTX 3090 (0.6% higher score) and the Radeon Pro 5300 (0.2% higher). The measured FPS in Thief, however, shows the RTX 5070 performing well above what these rival scores might suggest, particularly at lower resolutions where the CPU's six cores and 4.40 GHz boost clock keep the GPU fed.

The Ryzen 5 5600's 79th percentile ranking among CPUs is respectable, and its nearest rivals—the Intel Xeon D-1746TER and AMD EPYC 9554P—are workstation-class chips that would likely perform differently in gaming workloads. The CPU's 12 threads and 32 MB L3 cache are well-matched to the RTX 5070's needs in Thief, which does not heavily tax CPU resources.

The combo's rank within the top quarter of all tested configurations underscores its viability for this title. The 4K High result of 64.8 FPS and 1440p Ultra result of 104.9 FPS are both strong outcomes that justify the pairing. The data indicates that this combination delivers a well-balanced experience across all three resolutions, with the GPU's 12 GB memory and 672.0 GB/s bandwidth being the defining characteristics of its performance profile.
