Thief

How This Combo Ranks

This combination of Intel Core i5-14400F and NVIDIA GeForce GTX 1650 lands at rank 1579 out of 1642 tested combos for Thief. That places it in the bottom 4% of all configurations, a positioning that immediately signals a severe bottleneck for a game of this era. The rank is not surprising given the GPU's standing; the GTX 1650 sits at the 43rd percentile among all GPUs, with an average benchmark score of 8713. Its nearest rivals—the RTX 3050 A Mobile, Radeon 550X, Quadro P2200, and Radeon Pro WX 5100—are all within 0.5% of its score, meaning the performance envelope is tightly packed among low-end parts.

The CPU, by contrast, is a much stronger component. The i5-14400F ranks at the 88th percentile among all CPUs, with an average benchmark score of 32508. Its nearest rival, the Intel Core i7-12800H, scores 32513, a delta of 0%. The AMD Ryzen 5 PRO 7645 is 0.2% ahead, while the Ryzen 7 250 and i7-13705H are 0.2% behind. This 10-core, 16-thread processor is clearly not the limiting factor here. The data points to a lopsided pairing: a top-tier CPU strapped to a bottom-tier GPU, and Thief's frame rates reflect that imbalance.

GPU Role

The GTX 1650 brings 4 GB of GDDR5 memory on a 128-bit bus, with a bandwidth of 128.1 GB/s. Its base clock is 1485 MHz, boosting to 1665 MHz, and the memory runs at 2001 MHz (8 Gbps effective). These are modest specs for 2019 hardware, and Thief, released in 2014, should theoretically run well on such a card—but the measured FPS tells a different story. The GPU's pixel rate of 53.28 GPixel/s and texture rate of 93.24 GTexel/s are the raw throughput figures that dictate how many pixels and texels can be processed per second, and at higher resolutions these limits become stark.

The card's 896 shading units and 32 ROPs are the architectural resources that handle the game's lighting and shadow calculations, which are heavy in a stealth title like Thief. The benchmark scores for DirectX 11 (58 on PassMark) and DirectX 12 (35) suggest the card is not optimized for modern API overhead, but Thief's engine predates those concerns. The real issue appears to be VRAM capacity and fill rate—at 4K, the card simply runs out of headroom, as evidenced by the 18-28 FPS range across all settings at that resolution.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and reveals where the bottleneck lies. At 1080p Low, the combo achieves 74.7 FPS, which is playable. Moving to 1440p Low, it drops to 54 FPS—a 27.7% reduction. At 4K Low, it plummets to 28.4 FPS, a further 47.4% drop from 1440p. This scaling pattern is classic GPU-bound behavior: the CPU is capable of feeding the GPU at lower resolutions, but as pixel count increases, the GTX 1650's fill rate and memory bandwidth become the wall.

The delta between 1080p and 4K at High settings is even starker: 42.3 FPS down to 18.4 FPS, a 56.5% loss. At Ultra, the figures are 41.7 FPS at 1080p versus 18.6 FPS at 4K—a 55.4% drop. These numbers indicate that the GPU is the sole limiting component above 1080p; the CPU's high single-core score (3093 in Cinebench R23) is irrelevant once the GPU saturates. The data suggests that for any resolution above 1080p, the GTX 1650 is overwhelmed, and the frame rate collapses in a linear fashion with pixel count.

Measured FPS Breakdown

At 1080p, the results show a playable range depending on settings. Low delivers 74.7 FPS, Medium drops to 58.5 FPS, High falls to 42.3 FPS, and Ultra yields 41.7 FPS. The gap between Medium and High is 16.2 FPS, while the gap between High and Ultra is a mere 0.6 FPS—indicating diminishing returns beyond High. The 1080p Low figure is the only one that approaches the 60 FPS threshold comfortably, while Medium is borderline playable.

At 1440p, the numbers degrade noticeably. Low runs at 54 FPS, Medium at 37.6 FPS, High at 28.8 FPS, and Ultra at 26.3 FPS. The spread from Low to Ultra is 27.7 FPS, and even the best-case scenario (Low) is below 60 FPS. This resolution is marginal for smooth gameplay, and the data shows that only Low settings keep the frame rate above 50 FPS.

At 4K, the situation is dire. Low yields 28.4 FPS, Medium 24.2 FPS, High 18.4 FPS, and Ultra 18.6 FPS. The difference between High and Ultra is negligible (0.2 FPS), suggesting both are equally unplayable. The 4K figures are below 30 FPS in all cases, meaning the combo cannot maintain a consistent frame rate at this resolution regardless of visual fidelity. The data is clear: 4K is not viable for this pairing.

Settings Recommendations

Based on the measured rows, the optimal experience for this combo is at 1080p with Low settings, where the average FPS is 74.7. This is the only configuration that clears the 60 FPS bar with headroom. Medium at 1080p (58.5 FPS) is close to playable but may suffer from occasional dips below 60 FPS, which is risky for a stealth game requiring precise timing. High at 1080p (42.3 FPS) is smoother than 1440p Low (54 FPS), but the visual upgrade is minimal given the frame rate penalty.

For players prioritizing visual fidelity over frame rate, 1080p High at 42.3 FPS is a reasonable compromise—it stays above 30 FPS and offers better lighting and shadow detail. However, the Ultra preset at 1080p (41.7 FPS) offers almost no improvement over High (0.6 FPS difference), so there is no reason to select it unless the extra effects are worth the negligible cost. At 1440p, the data recommends Low (54 FPS) as the only viable option, but even that is below the ideal smoothness threshold. For 4K, no settings produce a playable result, so the recommendation is to avoid this resolution entirely.

CPU Role

The Intel Core i5-14400F is a 10-core, 16-thread processor with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. Its cache structure includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3. In Cinebench R23, it scores 21914 multi-core and 3093 single-core, which places it in the top 12% of all CPUs. This processing power is far beyond what Thief requires, as the game is from 2014 and was designed for much older hardware.

The CPU's role in this combo is to feed frames to the GPU without becoming a bottleneck. At 1080p Low, the 74.7 FPS result suggests the CPU is doing its job—it can push the GTX 1650 to its limits. However, at higher resolutions, the GPU's limitations dominate, and the CPU's high single-core performance (311 in Cinebench R15 single-core) cannot compensate. The data shows that the i5-14400F is not the limiting factor in any scenario; the GPU is. This is a textbook case of an unbalanced pairing where CPU headroom is wasted on a GPU that cannot keep up.
