Thief

The AMD Ryzen 5 8400F and NVIDIA GeForce RTX 3080 combination secures the 406th position out of 1,642 tested combos in Thief, placing it comfortably in the top quarter of all systems evaluated. This ranking reflects a balanced pairing where neither component severely bottlenecks the other, though the specific strengths and weaknesses of each part become evident when examining frame rates across different resolutions and settings. The combo’s standing suggests it delivers a consistently smooth experience at high refresh rates for 1080p and 1440p gaming, while still managing playable performance at 4K with adjusted settings.

How This Combo Ranks

At rank 406 of 1,642 tested combinations, this system sits in the 75th percentile of all configurations benchmarked for Thief. The position indicates a well-matched duo that outperforms the majority of setups while leaving headroom for more extreme hardware pairings. The CPU’s average benchmark score of 25,064 places it in the 82nd percentile of all processors, while the GPU’s average score of 35,787 positions it in the 80th percentile of all graphics cards, showing a slight edge in processor capability relative to the graphics component.

The CPU’s nearest rivals in synthetic testing include the AMD Ryzen 7 2700X with a delta of 0 percent, the AMD Ryzen AI 5 PRO 340 at -0.1 percent, the AMD EPYC 9474F at -0.2 percent, and the AMD Ryzen 5 7500F at 0.3 percent. This clustering indicates the 8400F delivers performance essentially identical to these alternatives in general compute workloads, though Thief’s specific engine behavior may favor certain architectural traits. For the GPU, the RTX 3080 sits near the AMD Radeon Pro Duo (-0.2 percent), AMD Radeon 880M (0.4 percent), AMD Radeon RX 7900 GRE (-0.9 percent), and NVIDIA GeForce RTX 5070 Ti Mobile (1 percent), demonstrating that its raw compute capability remains competitive even against newer silicon.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, manufactured on TSMC’s 4 nm process with 25,000 million transistors across a 178 mm² die. Its base clock of 4.20 GHz boosts up to 4.70 GHz, and the 16 MB shared L3 cache, alongside 1 MB L2 per core, provides adequate data locality for Thief’s stealth gameplay mechanics. The processor supports DDR5 memory with dual-channel configuration and a bandwidth of 83.2 GB/s, which proves sufficient for feeding the GPU in this 2014 title.

In synthetic tests, the CPU achieves a single-thread score of 951 in 3DMark and 2,943 in Cinebench R23, indicating strong per-core performance that helps maintain high frame rates in scenarios where the game’s simulation thread becomes a limiting factor. The multi-threaded results show a 16-thread score of 6,091 in 3DMark and 20,851 in Cinebench R23, with multithread scores scaling to 24,530 in PassMark. Thief, being a title from 2014, does not heavily utilize many cores, so the 6-core configuration with high clocks is more advantageous than a higher-core-count part with lower frequencies.

The CPU’s 65 W TDP and unlocked multiplier allow for efficient operation, but the benchmark data indicates that in this game, the processor rarely becomes the primary constraint. At lower resolutions and settings where frame rates exceed 160 FPS, the CPU’s ability to feed the GPU with draw calls and physics calculations becomes more critical, yet the measured performance shows no dramatic falls that would suggest a bottleneck. The 25,064 average benchmark score, sitting 0 percent from the Ryzen 7 2700X and 0.3 percent ahead of the Ryzen 5 7500F, confirms this processor delivers consistent, predictable results that align with its mid-range positioning.

GPU Role

The NVIDIA GeForce RTX 3080 pairs 10 GB of GDDR6X memory on a 320-bit bus with a bandwidth of 760.3 GB/s, offering ample memory capacity and throughput for Thief’s textures and effects at all tested settings. The GA102 chip, built on Samsung’s 8 nm process with 28,300 million transistors, features 8,704 shading units, 272 texture mapping units, and 96 raster output units. Its boost clock of 1,710 MHz, up from a base of 1,440 MHz, drives a pixel rate of 164.2 GPixel/s and a texture rate of 465.1 GTexel/s, with FP32 performance reaching 29.77 TFLOPS.

The GPU’s average benchmark score of 35,787 places it in the 80th percentile of all graphics cards, with its closest rival being the AMD Radeon Pro Duo at just -0.2 percent difference. The 3DMark Steel Nomad DX12 score of 4,407 and Geekbench Vulkan score of 145,176 indicate strong modern API performance, though Thief’s DirectX 11 renderer benefits more from raw rasterization throughput than ray tracing or tensor cores. The 68 RT cores and 272 tensor cores remain largely idle in this title, but the traditional shading units handle the game’s geometry and lighting efficiently.

The 320 W TDP and dual-slot design with a 12-pin power connector reflect the GPU’s high power requirement, yet the benchmark results show it delivers substantial performance headroom in Thief. At 1080p Ultra settings, the RTX 3080 produces 135.6 FPS average, demonstrating that it can easily drive high refresh rate monitors even with maximum visual fidelity. The 10 GB VRAM capacity proves sufficient for this game, as no memory-related performance degradation appears when moving from Medium to Ultra settings across all resolutions.

Measured FPS Breakdown

At 1920x1080, the combo delivers an average of 180.7 FPS on Low settings, dropping to 162.7 FPS on Medium, 142.6 FPS on High, and 135.6 FPS on Ultra. The difference between Low and Ultra settings is 45.1 FPS, representing a 25 percent reduction in frame rate when maximizing visual quality. The 1080p results show diminishing returns from High to Ultra, with only a 7 FPS difference, suggesting that Ultra settings impose additional GPU load without proportionally larger performance penalties.

Moving to 2560x1440, the measured averages are 160.1 FPS on Low, 129.3 FPS on Medium, 96.4 FPS on High, and 94.2 FPS on Ultra. The gap between Low and Medium widens to 30.8 FPS, while High and Ultra remain close at a 2.2 FPS difference. At 1440p, the GPU begins to show its workload, as the 10 GB memory and 320-bit bus handle the increased pixel count, but the frame rates still exceed 90 FPS even at maximum settings, providing smooth gameplay for most displays.

At 3840x2160, the averages fall to 100.4 FPS on Low, 73.7 FPS on Medium, 59.8 FPS on High, and 53.6 FPS on Ultra. The 4K resolution substantially increases GPU demand, with Low settings maintaining triple-digit frame rates while Ultra dips below 60 FPS. The step from Medium to High costs 13.9 FPS, and High to Ultra costs an additional 6.2 FPS, showing that visual quality settings have a more pronounced impact at higher resolutions. The 53.6 FPS average at 4K Ultra remains playable, though not ideal for competitive play or high refresh rate displays.

Resolution Scaling

Scaling from 1080p to 1440p at Ultra settings reduces the average frame rate from 135.6 FPS to 94.2 FPS, a 30.5 percent decrease that aligns with the 77 percent increase in pixel count. This nearly proportional scaling indicates that the GPU becomes the limiting component at these settings, as the CPU has sufficient headroom to maintain its performance. The same resolution step at Low settings shows a smaller relative drop from 180.7 FPS to 160.1 FPS, an 11.4 percent reduction, suggesting that at lower settings the CPU starts to constrain the maximum achievable frame rate.

When scaling from 1440p to 4K at Ultra settings, the frame rate falls from 94.2 FPS to 53.6 FPS, a 43.1 percent decrease against a 125 percent pixel increase. This steeper decline per pixel indicates that the RTX 3080’s memory bandwidth and shading throughput become the dominant factors at 4K, with the CPU playing a diminished role. At Low settings, the 1440p to 4K transition shows a reduction from 160.1 FPS to 100.4 FPS, a 37.3 percent drop, which still reflects GPU-bound behavior but with less severe scaling due to reduced shader complexity.

The overall scaling pattern reveals that the AMD Ryzen 5 8400F provides sufficient single-thread performance to avoid becoming a bottleneck in Thief until frame rates approach 180 FPS. The RTX 3080, with its 760.3 GB/s bandwidth and 29.77 TFLOPS of FP32 compute, handles the rendering load across all settings, but its performance degrades predictably with resolution increases. The measured data shows a consistent relationship where each doubling of pixel count reduces frame rates by roughly 40-50 percent at high settings, confirming that this combo delivers balanced performance with the GPU as the primary limiter in most scenarios above 1080p.
