Thief

The Intel Core i5-10400F and NVIDIA GeForce RTX 5070 combination delivers a playable experience in Thief, but the data reveals a clear shift in bottleneck behavior as resolution increases. At 1080p, the system shows strong headroom, with average frame rates ranging from 99.6 FPS on Ultra to 125.7 FPS on Low. Moving to 1440p, the performance drops are modest: the High preset falls from 100.7 FPS to 87.7 FPS, a 13% reduction. The Low preset at 1440p still holds 107.7 FPS, indicating that even when graphical load increases, the CPU can maintain high output. The real inflection point occurs at 4K. At 3840x2160, the High preset drops to 64.7 FPS, and Ultra falls further to 63.1 FPS. The gap between 1440p High (87.7 FPS) and 4K High (64.7 FPS) is substantial, representing a 26% performance loss. This pattern strongly suggests that at 4K, the GPU becomes the primary limiting factor, as the pixel throughput demand outpaces what the RTX 5070 can deliver in this title. Conversely, the relatively small delta between 1080p and 1440p High (100.7 vs 87.7 FPS) implies that the CPU is still capable of feeding the GPU adequately at those resolutions. The 4K Low preset result of 91.3 FPS is particularly telling: even with minimal settings, the resolution itself imposes a hard ceiling, confirming that the RTX 5070’s rendering pipeline is the constraint at this resolution, not the processor.

How This Combo Ranks

The combination of the Core i5-10400F and RTX 5070 achieves a combo rank of 814 out of 1642 tested combos in Thief. This places it in the upper-middle tier of all tested systems, meaning it outperforms roughly half of the configurations in the database but falls short of the top performers. Broken down by component, the CPU sits at the 73rd percentile among all processors, with an average benchmark score of 14168. Its nearest rivals include the AMD EPYC 7552, which scores 14115 (a 0.4% delta), and the AMD Ryzen 3 7320C, which scores 14277 (a -0.8% delta). This puts the i5-10400F in a tightly contested band, where single-digit percentage differences separate it from server-class and newer mobile parts. The GPU, meanwhile, holds the 83rd percentile among all graphics cards, with an average benchmark score of 41687. Its closest competitors are the AMD Radeon Pro 5300 (41610, 0.2% delta) and the NVIDIA GeForce RTX 3090 (41441, 0.6% delta). Notably, the RTX 5070 edges out the RTX 3090 in aggregate benchmarks, which is a strong indicator of its generational efficiency. In Thief specifically, the combo’s 814th rank against 1642 other pairings suggests that while neither component is a bottleneck at lower resolutions, the overall system does not crack the top tier. This is likely due to the CPU’s aging architecture, as its single-threaded score of 688 in 3DMark is modest by modern standards, capping performance in a game that relies on consistent frame pacing.

GPU Role

The RTX 5070 is built on the Blackwell 2.0 architecture with a 5 nm process and contains 31,100 million transistors on a 263 mm² die. Its memory configuration is a defining feature: 12 GB of GDDR7 on a 192-bit bus, delivering 672.0 GB/s of bandwidth. This bandwidth is crucial for Thief at higher resolutions, where texture streaming and memory access patterns become more demanding. The GPU’s clock speeds are set at a base of 2325 MHz and a boost of 2512 MHz, with memory running at 1750 MHz (28 Gbps effective). These clocks allow the card to achieve a pixel rate of 201.0 GPixel/s and a texture rate of 482.3 GTexel/s, which explains its ability to push 64.7 FPS at 4K High. The 48 ray tracing cores and 192 tensor cores are present, but Thief’s 2014 release predates widespread RT implementation, so the game likely relies on the traditional rasterization pipeline. The raw FP32 throughput of 30.87 TFLOPS is what drives the standard rendering workload. In benchmark terms, the GPU’s PassMark G3D score of 29137 places it well above the median, but its DirectX 9 score of 320 and DirectX 10 score of 180 suggest that older API paths are not where this card excels. The data shows a clear pattern: at 4K, the GPU’s memory bandwidth becomes the limiting factor, as evidenced by the 26% drop from 1440p to 4K on High settings. The card’s 12 GB VRAM is sufficient for this game, as no VRAM-related stutters are indicated in the measured FPS, but the 192-bit bus is narrower than what high-end cards typically use, which may explain why Ultra settings at 4K yield only 63.1 FPS.

FAQ

*Q: What is the best resolution for this combo in Thief?*

A: The data shows 1440p as the sweet spot. At 2560x1440, High settings deliver 87.7 FPS, while Ultra achieves 91.5 FPS. This represents a 35% improvement over 4K High (64.7 FPS) without sacrificing visual quality, and the CPU is still able to keep pace.

Q: How does the RTX 5070 compare to its nearest GPU rivals?

A: The RTX 5070’s average benchmark score is 41687, which is 0.6% higher than the NVIDIA GeForce RTX 3090 (41441) and 0.2% higher than the AMD Radeon Pro 5300 (41610). It trails the AMD Radeon Pro 580X by 0.7% (41991), placing it in a very tight performance band.

Q: Is the i5-10400F a bottleneck at 1080p?

A: No. At 1080p Low, the system hits 125.7 FPS, and at 1080p Ultra it maintains 99.6 FPS. The CPU’s 6 cores and 12 threads, boosted to 4.30 GHz, are sufficient to drive these frame rates, as the delta between Low and Ultra at 1080p is only 21%.

Q: Why does 4K performance drop so sharply?

A: The GPU becomes the limiting factor. Moving from 1440p High (87.7 FPS) to 4K High (64.7 FPS) is a 26% reduction, while the CPU’s load does not scale proportionally with resolution. The RTX 5070’s 672.0 GB/s bandwidth is strained by the 3840x2160 pixel count.

Q: What is the combo’s overall standing?

A: The combination ranks 814 out of 1642 tested combos in Thief, placing it just above the median. The CPU’s 73rd percentile and GPU’s 83rd percentile suggest the graphics card is the stronger component, but the pairing does not break into the top quartile of systems.

*Q: Does the GPU’s VRAM size affect Thief performance?*

A: The 12 GB GDDR7 configuration appears sufficient. The measured FPS shows no signs of texture thrashing or severe drops, with the minimum FPS values being null in the data. The bottleneck at 4K is bandwidth-driven, not capacity-driven.

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor from the Comet Lake architecture, built on a 14 nm process. Its base clock of 2.90 GHz boosts up to 4.30 GHz, and it accesses 12 MB of shared L3 cache. In the context of Thief, a game released in 2014, this CPU is more than adequate for the core game logic and AI, but its performance ceiling is defined by its single-thread capabilities. The 3DMark single-thread score of 688 and Cinebench R23 single-core score of 1453 indicate modest per-core throughput compared to modern parts. However, the game’s threading model benefits from the 12 threads, as evidenced by the Cinebench R23 multicore score of 10297. The nearest CPU rivals paint a clear picture: the AMD EPYC 7552 (14115 avg) is only 0.4% slower, while the Intel Core i5-8500 (14332) is 1.1% faster in aggregate benchmarks. This puts the i5-10400F in a crowded field where its age is not a major disadvantage. In Thief specifically, the CPU’s role becomes more pronounced at lower resolutions. At 1080p, the difference between Low (125.7 FPS) and Ultra (99.6 FPS) is 26%, which suggests the CPU can still feed the GPU at high frame rates. However, at 4K, the frame rates compress to a range of 63.1 to 91.3 FPS, indicating that the CPU is no longer the limiting factor. The 65W TDP and dual-channel DDR4 memory support (42.7 GB/s bandwidth) are adequate for this workload, but the PCIe Gen 3 interface may slightly reduce data transfer rates to the RTX 5070 compared to newer systems, though this does not manifest as a measurable bottleneck in the provided FPS data.

Settings Recommendations

For the best balance of visual fidelity and frame rate, the data points to the High preset as the optimal choice across most resolutions. At 1080p, High yields 100.7 FPS, which is smooth and only 1% lower than Ultra’s 99.6 FPS, while providing the same visual quality in most respects. At 1440p, High delivers 87.7 FPS, which is sufficient for immersive stealth gameplay, and it is only 4 FPS behind Ultra (91.5 FPS) — a negligible difference that does not justify the extra rendering load. The Medium preset at 1440p (102 FPS) offers a 16% boost over High, but the visual downgrade is generally not worth it for a game that relies on ambient lighting and shadow detail. At 4K, the decision becomes more nuanced. High (64.7 FPS) is playable, but Ultra (63.1 FPS) drops below the 60 FPS threshold that many players consider the minimum for smoothness. The Low preset at 4K (91.3 FPS) is the only option that provides significant headroom, but it sacrifices the atmospheric effects that define Thief’s stealth mechanics. Therefore, for 4K, the recommended path is to stick with High and accept the 64.7 FPS average, as it maintains the game’s intended visual style without falling into sub-60 territory. For players prioritizing frame rate over fidelity, the Medium preset at 1440p (102 FPS) is the best compromise, as it stays well above 100 FPS while retaining moderate detail levels. The Ultra preset is only recommended for 1080p (99.6 FPS) where the hardware can handle it, but the 1% difference from High suggests it is not a worthwhile investment. In summary, High settings at 1440p or 1080p provide the best experience, with 4K High being a viable option for those with a 4K display who can tolerate 64.7 FPS.
