# Thief with AMD Ryzen 5 8400F + NVIDIA GeForce RTX 5070 Ti

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 5070 Ti delivers a remarkably consistent performance profile across Thief's resolution and settings ladder, with the data showing a system that scales predictably from 1080p to 4K. At 1920x1080 with Low settings, the combo reaches 182.5 FPS average, while the same resolution at Ultra drops to 148.2 FPS — a 19% reduction that indicates the CPU is keeping pace with the GPU's output. The measured results place this combination at rank 174 out of 1642 tested combos in this game, placing it in the top 11% of all configurations.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals a system that maintains playable performance even at the highest resolution, though the scaling pattern shows where the bottleneck shifts. At High settings, the average FPS drops from 149.4 at 1920x1080 to 126.4 at 2560x1440, then falls to 72.8 at 3840x2160. This represents a 51% reduction from 1080p to 4K, which is a moderate scaling curve for a title from 2014 running on modern hardware.

The Low settings preset tells a different story about the limiting component. At 1920x1080 Low, the system produces 182.5 FPS; at 2560x1440 Low, it reaches 157.8 FPS; and at 3840x2160 Low, it still manages 126.8 FPS. The relatively small delta between 1080p and 1440p at Low settings — only 14% — suggests that at lower graphical loads, the CPU begins to assert its influence on the frame rate ceiling. The RTX 5070 Ti's 16 GB of GDDR7 memory on a 256-bit bus with 896.0 GB/s bandwidth is clearly not the limiting factor at these settings.

Ultra settings show the most dramatic resolution scaling, with 148.2 FPS at 1080p dropping to 119 FPS at 1440p and then to 67.9 FPS at 4K. The 4K Ultra figure represents a 54% decline from the 1080p Ultra result, which is the steepest drop across all settings presets. This pattern indicates that at 4K Ultra, the GPU is being pushed to its limits, with the pixel rate of 235.4 GPixel/s and texture rate of 686.6 GTexel/s becoming the governing constraints.

CPU Role

The AMD Ryzen 5 8400F contributes to this game's performance through its 6 cores and 12 threads running on the Zen 4 (Phoenix) architecture at a 4.2 GHz base clock and 4.7 GHz boost clock. The processor's single-thread performance, as measured by the 3dmark single-thread score of 951 and Cinebench R20 single-core score of 1236, provides the foundation for Thief's frame pacing at lower resolutions where the GPU is not saturated.

The CPU's multi-threaded capacity is substantial for a 6-core part, with a Cinebench R23 multicore score of 20851 and a 3dmark max threads score of 6165. However, Thief, being a stealth title from 2014, does not heavily utilize many threads; the data suggests that the 8400F's 16 MB of shared L3 cache and 83.2 GB/s dual-channel DDR5 memory bandwidth are sufficient to feed the RTX 5070 Ti without creating a significant CPU bottleneck at 1080p.

The 8400F's nearest rivals include the AMD Ryzen 7 2700X with an average score of 25057 (0% delta), the AMD Ryzen AI 5 PRO 340 at 25099 (-0.1%), and the AMD EPYC 9474F at 25103 (-0.2%). The Ryzen 5 7500F sits slightly below at 24993 (0.3% delta). This grouping shows that the 8400F's overall benchmark average of 25064 places it in the 82nd percentile of all CPUs, indicating strong performance for its core count.

GPU Role

The NVIDIA GeForce RTX 5070 Ti serves as the primary performance driver in this configuration, particularly at higher resolutions and settings. With 8960 shading units, 280 texture mapping units, and 96 ROPs, the GPU's raw compute capabilities — 43.94 TFLOPS FP32 — provide ample headroom for Thief's DirectX 11-era rendering workload. The 70 RT cores and 280 tensor cores are present but less relevant for this title, which predates widespread ray tracing adoption.

The GPU's memory subsystem is a defining feature: 16 GB of GDDR7 on a 256-bit interface delivering 896.0 GB/s bandwidth. This configuration ensures that even at 4K Ultra settings, where the average FPS drops to 67.9, the system is not memory-constrained. The data shows a clear GPU-bound trend at 4K across all settings — the difference between Low (126.8 FPS) and Ultra (67.9 FPS) at this resolution is 87%, demonstrating that graphical complexity directly drives the performance envelope.

The RTX 5070 Ti's benchmark results show a Passmark G3D score of 32974 and a 3dmark Steel Nomad DX12 score of 6604, placing it in the 87th percentile of all GPUs. Its nearest rival is the NVIDIA GeForce RTX 4080 with an average score of 52085 (0% delta), with the AMD Radeon RX 7700S at 52505 (-0.8%) and the AMD Radeon Pro W6600M at 53414 (-2.5%) nearby. This competitive positioning means the GPU is well-matched to the CPU in this pairing, with neither component dramatically outpacing the other in synthetic benchmarks.

FAQ

Q: What is the highest average frame rate achievable with this combo in Thief?

A: The maximum measured average FPS is 182.5 at 1920x1080 with Low settings, while the 1080p Ultra preset still delivers 148.2 FPS.

Q: How does the combo perform at 4K Ultra settings?

A: At 3840x2160 with Ultra settings, the system averages 67.9 FPS, which is a 54% reduction from the 148.2 FPS seen at 1080p Ultra.

Q: Is the CPU or GPU the limiting factor at 1080p?

A: At 1080p Low, the CPU's influence becomes apparent — the delta between Low (182.5 FPS) and Medium (166.4 FPS) is only 9%, suggesting the 8400F's single-thread performance is governing the ceiling rather than the GPU.

A: This pairing ranks 174th out of 1642 tested combos in Thief, placing it in the top 11% of all configurations in the database.

Q: How does the GPU compare to its nearest competitor in benchmarks?

A: The RTX 5070 Ti's average benchmark score of 52086 is essentially tied with the RTX 4080 at 52085 (0% delta), while it trails the AMD Radeon Pro W6600M by 2.5%.

Q: Does the 16 GB VRAM capacity affect performance at any tested settings?

A: The data shows no VRAM-related stutters or anomalies; even at 4K Ultra, where the 16 GB GDDR7 pool is most heavily taxed, the system maintains a 67.9 FPS average, indicating adequate memory capacity.

How This Combo Ranks

With a combo rank of 174 out of 1642 tested configurations, the Ryzen 5 8400F and RTX 5070 Ti pairing sits comfortably in the upper tier of systems tested in Thief. This placement reflects the balance between the CPU's 82nd percentile standing and the GPU's 87th percentile positioning, with the combined performance exceeding what either component would achieve with a less capable partner.

The rank is particularly notable given Thief's age and its relatively modest thread utilization. The 8400F's strong single-thread performance — evidenced by its 3dmark single-thread score of 951 and Passmark single-thread score of 3684 — allows it to stay ahead of the GPU in frame delivery at 1080p, while the RTX 5070 Ti's substantial compute resources dominate at 4K. This creates a configuration that is never severely bottlenecked by either component, as shown by the smooth frame rate progression across all resolution and settings combinations.

The 174th position out of 1642 combos means the system outperforms roughly 89% of tested configurations in this title. This is a strong showing for a 6-core CPU paired with a high-end GPU, confirming that Thief responds well to the combination of moderate core count with high per-core efficiency. The data indicates that users seeking higher frame rates at 4K would need to sacrifice settings rather than upgrade components, as the 67.9 FPS at 4K Ultra is the limiting case for this pairing.
