Thief

The pairing of the Intel Core i5-14600KF with the NVIDIA GeForce RTX 4070 produces a wide performance envelope in Thief, scaling from a highly fluid 1080p experience to a playable but more demanding 4K one. The measured data reveals a system where the GPU becomes the primary constraint as resolution increases, while the CPU’s strong single-threaded performance ensures high frame rates at lower resolutions. This analysis examines the resolution scaling, optimal settings, and the individual roles of the processor and graphics card in shaping the game’s performance profile.

Resolution Scaling

The measured frames per second data shows a clear and predictable decline as resolution increases from 1920x1080 to 3840x2160, with the magnitude of the drop varying significantly based on the chosen quality preset. At the High preset, the system delivers 148.1 FPS at 1920x1080, which falls to 99.6 FPS at 2560x1440, a reduction of approximately 33%, and then further drops to 62.7 FPS at 3840x2160, representing a substantial 58% decrease from the 1080p baseline. This pattern indicates that at 1080p, the frame rate is not fully constrained by the GPU, allowing the processor to push performance higher, but as pixel count increases, the demand on the graphics card grows exponentially.

The Low preset exhibits the most dramatic scaling, starting at 208.2 FPS at 1080p and dropping to 175 FPS at 1440p and 101.1 FPS at 4K. The 1080p result suggests that the CPU is the limiting factor at this resolution and setting, as the frame rate is exceptionally high and the GPU has ample headroom. Moving to 4K Low, the frame rate drops by over half, illustrating how the pixel fill rate and memory bandwidth of the RTX 4070 become the dominant bottlenecks. The Ultra preset shows the steepest relative decline, from 137.9 FPS at 1080p to 57 FPS at 4K, which is a 59% reduction, highlighting that the most demanding settings place an immediate and heavy load on the GPU even at lower resolutions.

The data suggests that the limiting component shifts with resolution. At 1920x1080, across all presets, the system achieves frame rates well above 130 FPS, indicating that the CPU and GPU are both capable, but the CPU’s performance ceiling is likely reached first in lower-detail settings. At 2560x1440, the frame rates remain high, with the High preset at 99.6 FPS and Medium at 135.1 FPS, showing a balanced workload. At 3840x2160, the GPU is unequivocally the limiting factor, as even the Low preset only reaches 101.1 FPS, and the Ultra preset struggles to maintain 60 FPS, falling to 57 FPS. For a smooth 4K experience, users would need to accept lower settings, while 1440p represents a sweet spot where high quality and high frame rates can coexist.

Settings Recommendations

The measured rows provide a clear hierarchy of performance across the four available presets, allowing for specific recommendations based on target resolution and desired fluidity. At 1920x1080, the Ultra preset is the optimal choice for visual fidelity, delivering 137.9 FPS, which is well above the threshold for smooth gameplay on high-refresh-rate monitors. The Medium preset offers a marginal performance gain at 191.6 FPS, but the visual upgrade from Medium to Ultra is typically substantial in a 2014 title, making the slight frame rate sacrifice worthwhile. The High preset at 148.1 FPS sits between the two, but the Ultra setting provides the best balance of image quality and performance at this resolution.

At 2560x1440, the High preset emerges as the best experience, achieving 99.6 FPS. This is a significant drop from the 148.1 FPS seen at 1080p, but it remains highly playable and offers a strong visual upgrade over Medium. The Ultra preset at 94.7 FPS is also viable, staying above 60 FPS and delivering maximum detail, but the 5 FPS difference between High and Ultra suggests that High provides nearly the same experience with less strain on the GPU. The Medium preset at 135.1 FPS is an option for those prioritizing frame rate, but it forgoes the visual richness that the High and Ultra settings provide.

At 3840x2160, the recommendations change drastically due to the GPU’s heavy load. The High preset averages 62.7 FPS, which is just above the 60 FPS target, making it the highest quality setting that maintains playable frame rates. The Medium preset at 77.3 FPS provides a more comfortable margin above 60 FPS and is the safer choice for consistent performance, while the Low preset at 101.1 FPS offers a high-speed experience but with significant visual compromises. The Ultra preset at 57 FPS is the only measured configuration that falls below 60 FPS, making it unsuitable for smooth gameplay. For 4K, the data suggests that High is the best compromise between visual fidelity and performance, with Medium serving as a more reliable fallback.

GPU Role

The NVIDIA GeForce RTX 4070, based on the Ada Lovelace architecture and fabricated on a 5 nm process at TSMC, is the primary driver of the frame rate differences seen at higher resolutions. Its memory configuration includes 12 GB of GDDR6X on a 192-bit bus, providing a bandwidth of 504.2 GB/s, which is critical for feeding the GPU’s 5888 shading units at 4K. The boost clock of 2475 MHz, up from a base of 1920 MHz, allows the card to maintain high throughput under load, as evidenced by its solid performance in the game’s most demanding settings.

The GPU’s benchmark scores contextualize its raw capability, with a Passmark G3D score of 26927 and a 3DMark Steel Nomad DX12 score of 3854. In the database’s ranking, the RTX 4070 holds an 81st percentile against all GPUs, indicating it is a high-end part. Its nearest rivals include the AMD Radeon RX Vega 56, which scores 37507 in the aggregate benchmark, a mere 0.6% difference, and the NVIDIA GeForce RTX 4080 Mobile at 38135, which is 2.2% faster. This proximity in synthetic scores, however, does not fully translate to Thief, where the RTX 4070’s specific architecture and driver optimization likely contribute to its measured performance.

The data shows that the GPU’s role becomes increasingly dominant as resolution scales. At 1080p, the RTX 4070 is not fully utilized, as the frame rates at High and Ultra settings (148.1 and 137.9 FPS respectively) suggest that the CPU is keeping pace. However, at 4K Ultra, the card’s limitations are exposed, with the frame rate dropping to 57 FPS. This indicates that the 12 GB of VRAM and the 504.2 GB/s bandwidth are sufficient for the game’s textures and geometry at 4K, but the raw computational power of the GPU is the bottleneck. The card’s 29.15 TFLOPS of FP32 performance is substantial, yet Thief’s engine appears to be highly sensitive to resolution scaling, confirming that the RTX 4070 is a capable 1440p performer and a moderate 4K one.

How This Combo Ranks

The combination of the Intel Core i5-14600KF and the NVIDIA GeForce RTX 4070 ranks 246th out of 1642 tested combinations in Thief, placing it in the top 15% of all systems evaluated. This high ranking reflects the strong synergy between the two components, where the CPU’s high single-threaded performance supports the GPU’s capabilities without holding it back at lower resolutions. The rank of 246 out of 1642 suggests that while there are many faster configurations, this pairing is significantly above average and capable of delivering an excellent gaming experience.

The CPU’s own benchmark profile supports this ranking. The i5-14600KF achieves a 93rd percentile against all CPUs, with an average benchmark score of 49367. Its nearest rivals include the Intel Core i5-14600K, which scores 49166 and is only 0.4% slower, and the AMD Ryzen 9 5950X, which scores 49062 and is 0.6% slower. This places the i5-14600KF in a performance tier that is competitive with higher-core-count processors, even though it uses a hybrid architecture with 14 cores and 20 threads. In the context of Thief, which is a 2014 title likely optimized for fewer threads, the CPU’s strong single-core performance is more valuable than its multi-core might suggest.

The GPU’s ranking is also notable, as it sits at the 81st percentile against all GPUs. Its nearest rival, the AMD Radeon RX Vega 56, is only 0.6% off its aggregate score, yet the RTX 4070’s newer architecture and features likely provide a better experience in modern titles. The combo’s 246th rank out of 1642 is a holistic measure that accounts for both components, and the data indicates that this system is well-balanced for Thief. The high rank is not due to extreme performance in one area but rather a consistent delivery of high frame rates across all resolutions, which is a hallmark of a well-matched CPU-GPU pairing.

CPU Role

The Intel Core i5-14600KF, part of the Raptor Lake Refresh family, is a 14-core, 20-thread processor with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. Its architecture features 24 MB of shared L3 cache and 2 MB of L2 cache per core, which helps reduce latency and improve performance in gaming workloads. The CPU’s single-threaded performance is exceptional, as shown by its Cinebench R23 single-core score of 4643 and Geekbench single-core score of 2778, making it well-suited for games that rely on a few fast cores.

In Thief, the CPU’s role is most evident at 1080p resolution, where the frame rates are exceptionally high. At the Low preset, the system achieves 208.2 FPS, which is likely near the CPU’s maximum frame generation capability. This is supported by the fact that moving from Low to Medium at 1080p only reduces the frame rate by 16.6 FPS (to 191.6 FPS), while moving from High to Ultra reduces it by 10.2 FPS (from 148.1 to 137.9 FPS). This smaller delta between presets at 1080p compared to 4K suggests that the CPU is the limiting factor at this resolution, as the GPU is not being fully stressed.

The CPU’s high boost clock of 5.30 GHz is a significant advantage in Thief, as the game’s engine likely benefits from high IPC and clock speed rather than raw core count. The processor’s 14 cores and 20 threads provide ample headroom for background tasks, but the game’s performance is more dependent on the single-core speed. This is reflected in the CPU’s Cinebench R20 single-core score of 1950, which is among the highest for desktop processors. As resolution increases to 1440p and 4K, the CPU’s influence diminishes, and the GPU becomes the dominant factor, but the i5-14600KF ensures that it never becomes a bottleneck, allowing the RTX 4070 to perform at its full potential. The data confirms that this processor is an excellent match for this GPU in Thief, providing high frame rates at 1080p and enabling smooth gameplay at higher resolutions.
