Thief

Thief, released in 2014, remains a demanding title for modern hardware, and the combination of the AMD Ryzen 5 5600 and NVIDIA GeForce RTX 5090 D presents a fascinating case study in bottleneck dynamics. The measured data shows a system capable of high frame rates across all resolutions, yet the scaling patterns reveal a clear division of labor between the CPU and GPU. This analysis examines the measured FPS rows to determine where the limits lie and how this specific pairing performs against a vast database of other tested configurations.

Resolution Scaling

The frame rate progression from 1080p to 4K clearly illustrates how the performance bottleneck shifts as pixel count increases. At 1920x1080 with High settings, the average frame rate is 131 FPS. Moving to 2560x1440, this drops to 115 FPS, a reduction of 12.2%. At 3840x2160, the average falls further to 92 FPS, representing a 29.8% decrease from the 1080p figure. This pattern is consistent across all settings presets.

The scaling behavior indicates that at 1080p, the system is partially limited by the CPU. The Ryzen 5 5600, with its 6 cores and 12 threads, must feed frames to a very powerful GPU. The jump from 1080p to 1440p yields a relatively modest 12% performance hit, which suggests the CPU is still able to keep up reasonably well at the lower resolution. However, the more significant drop from 1440p to 4K—another 20% reduction—shows the GPU beginning to take over as the primary constraint.

At Low settings, the pattern is more pronounced. The 1080p Low preset achieves 160 FPS, while 1440p Low drops to 141 FPS (an 11.9% decrease), and 4K Low falls to 118 FPS (a 26.3% decrease from 1080p). The fact that the 4K Low score is still 26% lower than 1080p Low, despite the reduced graphical load, confirms that the GPU is heavily engaged at 4K. The RTX 5090 D, with its 32 GB of GDDR7 memory and 512-bit bus, is being pushed hard at this resolution, even with lower quality settings.

What is particularly telling is the gap between settings at each resolution. At 4K, the difference between Low (118 FPS) and Ultra (87 FPS) is 31 FPS, or 26.3%. At 1080p, that same Low-to-Ultra gap is also 31 FPS (160 vs 129 FPS), but the percentage difference is smaller at 19.4%. This suggests that at 1080p, the CPU limits the ceiling, compressing the range between presets. At 4K, the GPU is the limiter, and its performance scales more directly with the graphical workload.

GPU Role

The NVIDIA GeForce RTX 5090 D is a formidable piece of silicon, built on the Blackwell 2.0 architecture with a 5 nm process. Its base clock is 2017 MHz, boosting to 2407 MHz, and it houses 21760 shading units. The memory subsystem is equally impressive: 32 GB of GDDR7 running at 1750 MHz (28 Gbps effective) across a 512-bit bus yields a bandwidth of 1.79 TB/s. This massive bandwidth is critical for Thief at 4K, where texture data demands are high.

The GPU's benchmark scores confirm its position. In Passmark, it scores 44065 in G3D and 28396 in GPU compute, placing it in the 92nd percentile of all GPUs. Its average benchmark score is 77712, which puts it 1.1% above the AMD Radeon RX 6650M XT and 1.6% below the AMD Radeon RX 6850M XT. While these rivals are mobile parts, the deltaPct values show that the RTX 5090 D sits in a specific performance tier that these other cards approximate.

In Thief specifically, the GPU's role is most evident at 4K. The measured FPS at 4K Ultra is 87 FPS, which is the lowest score across all configurations. This is still a playable frame rate, but it represents the GPU hitting its limits with the most demanding settings. The fact that 4K Low (118 FPS) is only 31 FPS higher than 4K Ultra (87 FPS) suggests that even reducing the workload significantly cannot fully compensate for the pixel count. The GPU's raw compute and memory bandwidth are being saturated at this resolution, a signal of Thief's heavy use of lighting and shadow effects.

How This Combo Ranks

In the grand database of tested combinations, this pairing of the AMD Ryzen 5 5600 and NVIDIA GeForce RTX 5090 D holds a rank of 483 out of 2851 combos. This places it in the top 17% of all tested systems, which is a strong showing given the CPU's age. The Ryzen 5 5600, released in April 2022, is not the newest processor, but its Zen 3 architecture and 6-core/12-thread configuration still deliver solid performance.

The CPU's percentile rank is 74, meaning it outperforms 74% of all CPUs in the database. Its average benchmark score is 20468, which is nearly identical to its nearest rivals: the Intel Core Ultra 7 258V (20454, 0.1% slower), the AMD Ryzen 5 8500G (20425, 0.2% slower), and the AMD EPYC 9454P (20422, 0.2% slower). This clustering indicates that the Ryzen 5 5600 is well-matched to these other processors in general compute tasks.

However, the combo's rank of 483 out of 2851 suggests that while the CPU is competitive, the GPU is the star of this show. The RTX 5090 D's 92nd percentile ranking and its high memory bandwidth allow it to push frame rates that many other combos cannot achieve. The fact that this combo ranks in the top 17% despite the CPU being a mid-range part from a previous generation highlights how much the GPU dominates in this pairing.

Settings Recommendations

Based on the measured FPS data, the optimal settings balance depends heavily on the target resolution and desired frame rate. At 1920x1080, all presets deliver playable frame rates, with Low hitting 160 FPS and Ultra still managing 129 FPS. The Medium preset offers a good middle ground at 144 FPS, with a measured minimum of 123 FPS and maximum of 166 FPS. For competitive play or high refresh rate monitors, Low or Medium at 1080p is recommended to maximize frame rates.

At 2560x1440, the story is similar. High settings deliver 115 FPS, while Ultra drops slightly to 114 FPS. The Medium preset provides 127 FPS, with a minimum of 108 FPS and maximum of 147 FPS. Given the small gap between High and Ultra (only 1 FPS), it is advisable to select Ultra at 1440p if visual fidelity is a priority, as the performance cost is negligible. For those seeking higher frame rates, Medium is the better choice, offering a 10% improvement over Ultra.

At 3840x2160, the choices become more constrained. Ultra runs at 87 FPS, which is borderline for smooth gameplay on a 90Hz display. High settings improve this to 92 FPS, a 5.7% gain. Medium delivers 107 FPS, with a minimum of 91 FPS and maximum of 123 FPS, which is noticeably smoother. Low settings reach 118 FPS, but the visual quality degradation may not be worth the 10% gain over Medium. For 4K gaming, the Medium preset offers the best balance, providing frame rates above 100 FPS while maintaining reasonable visual quality.

Measured FPS Breakdown

At 1920x1080, the measured averages are as follows: Low runs at 160 FPS, Medium at 144 FPS, High at 131 FPS, and Ultra at 129 FPS. The Medium preset shows a minimum of 123 FPS and a maximum of 166 FPS, indicating some variance but generally consistent performance. The delta between Low and Ultra is 31 FPS, or 19.4%, which is the smallest relative spread of any resolution.

At 2560x1440, the averages are: Low at 141 FPS, Medium at 127 FPS, High at 115 FPS, and Ultra at 114 FPS. The Medium preset has a minimum of 108 FPS and maximum of 147 FPS. The gap between Low and Ultra here is 27 FPS, or 19.1%, which is proportionally similar to 1080p. Notably, the difference between High and Ultra is just 1 FPS, suggesting that the Ultra preset adds minimal additional load at this resolution.

At 3840x2160, the averages drop to: Low at 118 FPS, Medium at 107 FPS, High at 92 FPS, and Ultra at 87 FPS. The Medium preset's minimum is 91 FPS and maximum is 123 FPS. The spread between Low and Ultra is 31 FPS, or 26.3%, which is the largest percentage gap across all resolutions. This wider spread at 4K indicates that the GPU is the primary bottleneck, and its performance scales more steeply with settings changes.

CPU Role

The AMD Ryzen 5 5600 is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Vermeer. It operates on the AM4 socket with a base clock of 3.50 GHz and a boost clock of 4.40 GHz. The CPU has a 32 MB shared L3 cache and supports DDR4 memory in a dual-channel configuration, providing a memory bandwidth of 51.2 GB/s. Its TDP is 65 watts, making it an efficient part for its performance class.

In synthetic benchmarks, the Ryzen 5 5600 demonstrates solid multi-threaded capabilities. It scores 18309 in Cinebench R23 multi-core and 2584 in single-core. Its Passmark multi-thread score is 21541, with a single-thread score of 3256. These results place it in the 74th percentile of all CPUs, indicating it outperforms most processors in the database.

In Thief, the CPU's role is most apparent at lower resolutions. At 1080p, the frame rates are high across all settings, but the compression of scores between presets suggests the CPU is limiting the maximum achievable FPS. The 160 FPS at Low settings is likely near the ceiling for this CPU in this game. At 1440p and 4K, the GPU becomes the limiting factor, and the CPU's contribution diminishes. The fact that 4K Ultra still achieves 87 FPS demonstrates that the Ryzen 5 5600 can feed the RTX 5090 D adequately at higher resolutions, but it may be leaving some performance on the table at 1080p.
