# Thief Performance Analysis: Intel Core i5-14600KF + Intel Arc B370

The Intel Core i5-14600KF paired with the Intel Arc B370 delivers playable but constrained performance in Thief, a 2014 stealth title that remains demanding at higher resolutions. The measured frame rates show a system that is heavily GPU-limited, with the Arc B370's integrated-class performance bottlenecking the otherwise capable 14-core CPU. Across all tested settings and resolutions, the combo ranks 2634 out of 2851 total configurations in the database, placing it in the bottom tier of measured systems. The data reveals a clear pattern: at 1080p, the system can approach smooth gameplay on lower presets, but 4K Ultra is essentially unplayable, with average frame rates dipping into the high teens.

Resolution Scaling

The resolution scaling behavior of this configuration tells a straightforward story about where the bottleneck lies. Moving from 1920x1080 to 2560x1440 at High settings, the average frame rate drops from 45 FPS to 31 FPS, a 31% reduction. The jump from 1440p to 3840x2160 at High is even more severe, falling from 31 FPS to 18 FPS, another 42% loss. This compounding degradation pattern indicates the Intel Arc B370 is the limiting component; the GPU's rendering throughput simply cannot keep pace with the increasing pixel count.

At Low settings, the scaling curve shifts upward but retains the same shape. The system produces 78 FPS at 1080p, drops to 53 FPS at 1440p (a 32% decline), and then falls to 31 FPS at 4K (a 41% decline from 1440p). The consistency of these percentage drops—roughly one-third from 1080p to 1440p and then 40% from 1440p to 4K—suggests a purely pixel-bound scenario. The CPU, with its 14 cores and 5.30 GHz boost clock, is not the constraint; otherwise, the scaling would flatten out at higher resolutions as the GPU becomes the sole bottleneck, which is precisely what the data shows.

The Medium preset data, which includes minimum and maximum frame rates, reinforces this interpretation. At 1080p Medium, the average is 59 FPS with a minimum of 50 FPS and maximum of 68 FPS. At 1440p Medium, the average falls to 41 FPS with a minimum of 35 FPS and maximum of 47 FPS. At 4K Medium, the average drops to 24 FPS with a minimum of 20 FPS and maximum of 27 FPS. The narrow frame time variance at each resolution step—roughly 15-18 FPS between min and max—indicates consistent GPU workload without stuttering or CPU-induced hitches. This is a system that degrades gracefully but predictably as resolution increases.

FAQ

Q: Is the Intel Core i5-14600KF + Intel Arc B370 capable of running Thief at 1080p?

A: Yes, but only at lower settings. The measured data shows 78 FPS at Low, 59 FPS at Medium, 45 FPS at High, and 43 FPS at Ultra at 1920x1080. Medium is the highest preset that maintains an average above 60 FPS.

Q: How does this combo rank among all tested configurations for Thief?

Q: What frame rates can I expect at 1440p Medium settings?

A: The measured data shows an average of 41 FPS, with a minimum of 35 FPS and maximum of 47 FPS. This is playable but not smooth, and frame pacing may be noticeable in fast-moving stealth sequences.

Settings Recommendations

Based on the measured FPS rows, the optimal settings for this configuration depend heavily on the target resolution and acceptable frame rate floor. At 1920x1080, the Medium preset delivers 59 FPS average with a 50 FPS minimum, which is the sweet spot for a smooth stealth experience. The jump from Low (78 FPS) to Medium (59 FPS) costs 19 FPS but likely provides significant visual improvements in lighting and shadow quality, which are critical for a stealth game. High settings at 1080p drop to 45 FPS average, and Ultra falls to 43 FPS; these are playable but sacrifice the frame rate cushion needed for consistent stealth gameplay.

At 2560x1440, the situation becomes more constrained. Low settings produce 53 FPS average, which is acceptable for slower-paced stealth play. Medium drops to 41 FPS, and High falls to 31 FPS. Given that Thief emphasizes careful observation and timing over twitch reflexes, the Medium preset at 1440p might be tolerable for some players, but the data suggests Low is the more reliable choice for maintaining frame rate stability. Ultra at 1440p, at 29 FPS average, is not recommended.

For 3840x2160, no preset is truly playable. Low settings achieve 31 FPS average, Medium reaches 24 FPS, High drops to 18 FPS, and Ultra bottoms out at 17 FPS. Even the most forgiving stealth player would find sub-30 FPS frame rates detrimental to the experience. The measured frames and frame pacing at 4K indicate the Intel Arc B370 is overwhelmed, and players with 4K displays should either run the game at a lower resolution or accept a slideshow-like experience. The best experience across all resolutions is clearly 1080p Medium, which balances the 59 FPS average with the 50 FPS minimum, ensuring no major hitches during gameplay.

Measured FPS Breakdown

At 1920x1080, the configuration shows its strongest performance across all presets. Low settings deliver 78 FPS average, the highest measured frame rate in the entire dataset. Medium settings produce 59 FPS average with a minimum of 50 FPS and maximum of 68 FPS, showing a tight frame time distribution. High settings drop to 45 FPS average, and Ultra settings yield 43 FPS average. The gap between Low and Ultra at 1080p is 35 FPS, indicating that the graphical preset has a substantial impact on performance, but even the most demanding preset remains above 40 FPS.

At 2560x1440, performance drops noticeably across the board. Low settings achieve 53 FPS average, which is still respectable but 32% below the 1080p Low result. Medium settings fall to 41 FPS average with a minimum of 35 FPS and maximum of 47 FPS, representing a 31% decline from 1080p Medium. High settings produce 31 FPS average, and Ultra settings dip to 29 FPS average. The performance delta between Low and Ultra at 1440p is 24 FPS, a narrower spread than at 1080p, suggesting the GPU is becoming the limiting factor at higher pixel counts.

At 3840x2160, the system struggles to maintain playable frame rates. Low settings deliver 31 FPS average, which is the only 4K preset above 30 FPS. Medium settings produce 24 FPS average with a minimum of 20 FPS and maximum of 27 FPS, showing significant frame time variance. High settings drop to 18 FPS average, and Ultra settings bottom out at 17 FPS average. The performance gap between Low and Ultra at 4K is only 14 FPS, confirming that the GPU is completely saturated and no amount of graphical reduction can salvage a smooth experience at this resolution. The min and max frame data for Medium at 4K (20-27 FPS) reveals a 7 FPS range, which is proportionally larger than at lower resolutions, indicating less stable frame pacing under extreme GPU load.

GPU Role

The Intel Arc B370 is the definitive performance limiter in this configuration. Its 3DMark Steel Nomad DX12 score of 1184 places it at the 5th percentile among all GPUs, and its nearest rivals are all legacy ATI/AMD parts from over a decade ago. The GPU's compute specifications—1280 shading units, 40 texture mapping units, and 20 render output units—are modest, and its pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s reflect a design intended for integrated graphics duty rather than discrete gaming performance.

The Arc B370's memory configuration is particularly problematic for a game like Thief. The GPU uses System Shared memory, meaning it draws from the system's main memory pool via the IGP bus interface. The memory bandwidth is listed as System Dependent, which in a best-case scenario with DDR5 memory would still be far below what a dedicated graphics card offers. This shared memory architecture explains why the GPU's performance degrades so sharply with resolution increases; each higher resolution demands more memory bandwidth, and the system shared setup cannot deliver the required throughput. The 25 W TDP and lack of power connectors further confirm this is an integrated-class part, despite the "Arc B370" name suggesting a discrete product.

The GPU's clock behavior provides additional insight into the performance ceiling. With a base clock of 300 MHz and boost clock of 2400 MHz, the Arc B370 has a wide frequency range, but the thermal and power constraints of a 25 W design likely prevent sustained high clocks under load. The FP32 throughput of 6.144 TFLOPS and FP16 of 12.29 TFLOPS are competitive on paper for integrated graphics, but these numbers do not translate into playable Thief performance at 4K, where the GPU manages only 17-31 FPS depending on preset. The API support—DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4—is modern, but Thief's 2014 engine may not fully leverage these features, further limiting performance.

CPU Role

The Intel Core i5-14600KF is a high-performance desktop processor that is vastly underutilized in this gaming configuration. With 14 cores, 20 threads, and a boost clock of 5.30 GHz, the CPU has substantial computational headroom. Its benchmark scores confirm this: Cinebench R23 multi-core score of 32544, single-core score of 4594, and Geekbench multi-core of 17085 with single-core of 2445. The Passmark multi-thread score of 38697 and single-thread score of 4273 further demonstrate the CPU's capability. These results place the i5-14600KF at the 90th percentile among all CPUs, with an average benchmark score of 49394.

The CPU's nearest rivals illustrate its competitive positioning. The AMD Ryzen 9 7900 scores 49228 (0.3% lower), the AMD Ryzen 7 PRO 5755G scores 49196 (0.4% lower), and the Intel Core Ultra 5 245 scores 48995 (0.8% lower). Only the AMD Ryzen AI Max+ 388 scores higher at 49796 (0.8% higher). This tight clustering around the 49,000-49,800 range shows that the i5-14600KF is at the top of its class, with no significant CPU-side bottleneck in Thief.

The measured FPS data confirms the CPU is not limiting performance. If the CPU were the bottleneck, we would expect to see frame rate differences between the low and high settings to be minimal, as the GPU would be idle waiting for CPU instructions. Instead, the data shows substantial FPS variation between presets at each resolution, which is the hallmark of a GPU-bound scenario. For example, at 1080p, the difference between Low and Ultra is 35 FPS; at 1440p, it is 24 FPS; at 4K, it is 14 FPS. This shrinking delta with resolution is exactly what occurs when a GPU becomes progressively more saturated. The CPU's 24 MB of shared L3 cache and dual-channel DDR5 memory support provide more than enough bandwidth for Thief's engine, and the 10 nm process node with 257 mm² die size indicates a mature, efficient design that can sustain its 125 W TDP without thermal throttling. In this system, the CPU is ready for a far more powerful GPU, and any upgrade path would yield immediate frame rate improvements in Thief.
