Thief

How This Combo Ranks

The Intel Core i5-12400 paired with the NVIDIA GeForce RTX 4070 Ti secures the 261st position out of 1,642 tested combinations in Thief. This places the combo in the top 15.9% of all configurations analyzed, a strong showing for a mid-range CPU paired with a high-end GPU. The CPU itself sits at the 77th percentile among all processors, while the GPU ranks at the 85th percentile, indicating that the graphics card is the more dominant component in this pairing. The combination's overall standing reflects a balanced system where neither component is drastically outperforming the other, though the GPU's higher percentile suggests it carries more of the performance load in this particular title.

In synthetic benchmarks, the i5-12400 achieves an average score of 19,850, which places it within 0.1% of the Intel Core i7-9700 (19,831) and 0.2% ahead of the Intel Core i7-8700 (19,894). The delta against the AMD Ryzen Threadripper PRO 5995WX is a mere 0.4%, showing that this mainstream six-core processor holds its own against far more expensive workstation parts in general compute tasks. The i5-11600K trails by 0.4%, confirming that the 12th-generation architecture provides a meaningful uplift over its immediate predecessor. For the RTX 4070 Ti, the average benchmark score of 44,900 places it 0.6% behind the RTX 5090 Mobile and 1.5% behind the Intel Arc A730M, while it leads the AMD Radeon Pro 580 by 1.6% and the Radeon Pro 5500 XT by 1.6%. These narrow margins suggest that the GPU is operating at a performance tier where small architectural differences translate into minimal real-world deltas.

GPU Role

The RTX 4070 Ti brings 12 GB of GDDR6X memory across a 192-bit bus, delivering 504.2 GB/s of bandwidth. This memory configuration is substantial for a 2014 title like Thief, which was designed during an era when 2-4 GB of VRAM was typical. The ample memory capacity means that texture-heavy scenes at high resolutions will not be constrained by VRAM limitations, allowing the GPU to focus its resources on rendering rather than swapping data. The memory clock runs at an effective 21 Gbps, which contributes to the high bandwidth figure and supports smooth performance even when the engine demands rapid texture streaming.

The GPU's base clock of 2310 MHz and boost clock of 2610 MHz are notably high for a graphics card, reflecting the efficiency of the 5 nm TSMC process node. The Ada Lovelace architecture implements 7,680 shading units, 240 texture mapping units, and 80 raster output units, providing a robust foundation for pixel throughput. The pixel rate of 208.8 GPixel/s and texture rate of 626.4 GTexel/s indicate that the card can handle high fill-rate scenarios without bottlenecking. With 60 ray tracing cores and 240 tensor cores, the GPU is well-equipped for modern features, though Thief's original release predates widespread ray tracing adoption. The FP32 throughput of 40.09 TFLOPS gives the card substantial compute headroom, which is more than sufficient for a stealth game that primarily relies on lighting and shadow effects.

In Thief specifically, the GPU's role becomes evident when examining the measured frames per second across different settings. At 4K Ultra, the card produces 69.4 FPS, while at 1080p Low it reaches 168.6 FPS. The scaling between these extremes demonstrates that the GPU is the primary driver of performance, with the CPU providing sufficient support to avoid becoming a limiting factor. The 285 W TDP and 600 W suggested PSU rating reflect the power requirements needed to sustain these clock speeds, though the card's dual-slot design and 285 mm length make it a substantial physical presence in any chassis.

Settings Recommendations

For the best balance of visual fidelity and frame rate, the High preset at 1440p emerges as the recommended configuration. This setting delivers 121.9 FPS, which is comfortably above the 60 FPS threshold for smooth gameplay while still providing enhanced textures and lighting effects compared to Medium. The High preset at 4K produces 73 FPS, which is playable but leaves less headroom for demanding scenes. At 1080p, High yields 141.9 FPS, making it an excellent choice for high-refresh-rate monitors.

The Ultra preset represents the maximum visual quality but comes with diminishing returns. At 1440p, Ultra drops to 111.4 FPS, a 10.5 FPS reduction from High. At 4K, Ultra falls to 69.4 FPS, which is only 3.6 FPS below High and remains above the 60 FPS mark. Players who prioritize visual fidelity over raw frame rates can consider Ultra at 4K, but the marginal gains over High may not justify the performance cost. Medium settings provide a middle ground, with 135.8 FPS at 1440p and 95.1 FPS at 4K, though the visual downgrade from High is noticeable in a game that emphasizes atmosphere and shadow play.

Low settings offer the highest frame rates, with 152.8 FPS at 1440p and 120.6 FPS at 4K, but these come at the expense of the game's core aesthetic. Given that Thief is a stealth title where lighting and shadow are central to gameplay, sacrificing these elements for additional frame rate yields a suboptimal experience. The data suggests that High at 1440p strikes the ideal equilibrium, providing both the visual richness the game demands and the performance headroom for consistent gameplay.

Measured FPS Breakdown

At 1080p, the frame rate progression across settings shows a clear hierarchy. Low settings achieve 168.6 FPS, Medium reaches 153.9 FPS, High produces 141.9 FPS, and Ultra yields 135 FPS. The delta between Low and Ultra is 33.6 FPS, representing a 19.9% reduction in performance when maximizing visual quality. The step from Medium to High costs 12 FPS, while the step from High to Ultra costs only 6.9 FPS, indicating that the Ultra preset provides diminishing returns relative to its performance impact.

Moving to 1440p, the frame rates remain high but begin to show the GPU's workload increasing. Low settings produce 152.8 FPS, Medium delivers 135.8 FPS, High achieves 121.9 FPS, and Ultra drops to 111.4 FPS. The difference between Low and Ultra at 1440p is 41.4 FPS, or 27.1%, a larger percentage drop than at 1080p. This suggests that the GPU is becoming more heavily utilized as resolution increases, with the CPU still able to keep pace.

At 4K, the performance spread widens considerably. Low settings still manage 120.6 FPS, which is impressive for a 4K resolution. Medium produces 95.1 FPS, High drops to 73 FPS, and Ultra falls to 69.4 FPS. The gap between Low and Ultra at 4K is 51.2 FPS, or 42.5%, demonstrating that the higher resolution amplifies the performance cost of each settings tier. Notably, the jump from High to Ultra at 4K is only 3.6 FPS, making Ultra a more attractive option at this resolution than at lower ones where the cost is relatively higher.

Resolution Scaling

The transition from 1080p to 1440p to 4K reveals how the system's performance scales with resolution and which component becomes the limiting factor. At 1080p High, the system achieves 141.9 FPS. Moving to 1440p High, the frame rate drops to 121.9 FPS, a reduction of 20 FPS or 14.1%. At 4K High, the frame rate falls to 73 FPS, a further reduction of 48.9 FPS or 40.1% from the 1440p figure. This pattern indicates that the GPU is the primary bottleneck at higher resolutions, as the CPU's performance headroom remains constant regardless of resolution.

The Low settings preset provides a more dramatic illustration of this scaling. At 1080p Low, the system reaches 168.6 FPS. At 1440p Low, it drops to 152.8 FPS, a 15.8 FPS reduction. At 4K Low, it falls to 120.6 FPS, a 32.2 FPS reduction from 1440p. The percentage drops are 9.4% from 1080p to 1440p and 21.1% from 1440p to 4K, showing that even at the lowest settings, the GPU's rendering workload grows substantially with resolution.

The Ultra preset shows the steepest scaling curve. From 135 FPS at 1080p, the frame rate drops to 111.4 FPS at 1440p, a 17.5% reduction. At 4K, it plunges to 69.4 FPS, a 37.7% reduction from the 1440p figure. This steeper decline at Ultra settings confirms that the GPU is the limiting component, as the increased pixel count combined with maximum visual effects creates a compounding workload. The CPU's 6 cores and 12 threads, with a boost clock of 4.40 GHz, provide sufficient processing power to feed the GPU at all resolutions, but the RTX 4070 Ti's 12 GB of VRAM and 504.2 GB/s bandwidth ultimately determine the ceiling for frame rates as resolution increases.
