Thief

# FAQ

Q: What is the best playable setting for this combo in Thief at 4K?

A: At 3840x2160, the measured data shows High delivers 64.7 FPS average, which is above the 60 FPS threshold. Ultra drops to 60.7 FPS average, barely playable, while Medium reaches 86.1 FPS and Low hits 112.2 FPS. High is the safest choice for visual fidelity with a comfortable margin over the 60 FPS line.

Q: How much performance does the combo lose when going from 1080p to 4K?

A: At Ultra settings, the average FPS falls from 149.3 at 1920x1080 to 105.6 at 2560x1440 (a 43.7 FPS drop), and then to 60.7 at 3840x2160 (a further 44.9 FPS drop). The scaling is nearly linear, indicating the GPU becomes the limiting factor as resolution climbs.

Q: Which preset offers the highest frame rate at 1080p?

A: Low settings at 1920x1080 produce the highest measured average of 232.1 FPS. Medium follows at 205.4 FPS, High at 161.9 FPS, and Ultra at 149.3 FPS. The gap between Low and Medium is 26.7 FPS, while the jump from Medium to High is 43.5 FPS.

Q: Is the CPU or GPU more important for this game at 1440p?

A: At 2560x1440, the FPS spread across settings (187.3 Low, 141.8 Medium, 111.6 High, 105.6 Ultra) shows the GPU handling most of the load. The CPU, with 24 cores and 32 threads, is unlikely to bottleneck at these frame rates; the 105.6 FPS at Ultra still leaves headroom for CPU-bound scenarios.

Q: How does the combo rank relative to all tested configurations?

A: The combo ranks 126th out of 1,642 tested combinations in Thief, placing it in the top 8% of all tested configs. This is a strong result, though not top-tier, given the game's age and the hardware's modern capabilities.

Q: What is the FPS difference between High and Ultra at 1080p?

A: High averages 161.9 FPS, while Ultra averages 149.3 FPS at 1920x1080. The 12.6 FPS difference is modest, but Ultra may still be preferred for visual quality since both remain far above 144 Hz refresh rates.

# GPU Role

The NVIDIA GeForce RTX 5070 brings 12 GB of GDDR7 memory on a 192-bit bus, with a bandwidth of 672.0 GB/s. Its base clock is 2325 MHz with a boost of 2512 MHz, and the memory runs at 1750 MHz or 28 Gbps effective. For Thief, a game from 2014, these specifications are far beyond the minimum requirements, yet the measured FPS at 4K Ultra (60.7) shows the GPU is still the primary constraint at high resolutions.

The GPU's 6144 shading units and 80 ROPs handle the game's DirectX 11 rendering path, which is the likely API used given the era. The 12 GB VRAM is ample for Thief's textures, even at 4K Ultra, so memory capacity is not a limiting factor. Instead, the raw pixel throughput (201.0 GPixel/s) and texture rate (482.3 GTexel/s) determine the ceiling.

At 1080p, the RTX 5070 produces frame rates from 149.3 (Ultra) to 232.1 (Low), indicating the GPU is not heavily stressed at this resolution. The scenario reverses at 4K, where Ultra drops to 60.7 FPS, showing the GPU's fill-rate limits. The 30.87 TFLOPS FP32 performance is more than sufficient for this older title, but the data suggests that 4K Ultra sits near the edge of playability.

The RTX 5070's 48 RT cores and 192 tensor cores are irrelevant for Thief, which predates ray tracing and DLSS. The benchmark results therefore reflect pure rasterization performance. The GPU's percentile rank of 83 among all GPUs, with an average benchmark score of 41,687, places it slightly above the NVIDIA GeForce RTX 3090 (avg score 41,441) and below the Tesla M40 (41,897), though those are synthetic scores, not game-specific.

# Resolution Scaling

The measured FPS data shows a clear pattern: scaling from 1920x1080 to 3840x2160 reduces performance by roughly 50-60% depending on settings. At Ultra, the drop is from 149.3 to 60.7 FPS (a 59.3% reduction). At High, it falls from 161.9 to 64.7 FPS (a 60.0% reduction). Low settings see a drop from 232.1 to 112.2 FPS (a 51.7% reduction).

The 1440p results sit almost exactly halfway between 1080p and 4K in pixel count, and the FPS follows suit. At Ultra, 2560x1440 yields 105.6 FPS, which is 70.7% of the 1080p score and 174% of the 4K score. This linearity indicates the limiting component is the GPU's pixel processing capability, not the CPU or memory bandwidth.

At 1080p, the FPS range across settings spans 82.8 FPS (from 149.3 to 232.1), revealing significant headroom. At 4K, the range narrows to 51.5 FPS (from 60.7 to 112.2), showing that as resolution increases, the GPU becomes more saturated and settings have less relative impact. This is classic GPU-bound behavior, and the 24-core CPU is never the bottleneck.

The data suggests that 1440p is the sweet spot for this combo: Ultra offers 105.6 FPS, which is well above 60 FPS and close to 100 FPS, making it ideal for high-refresh monitors. At 4K, only Low (112.2 FPS) and Medium (86.1 FPS) provide comfortable margins, while High and Ultra hover near the 60-65 FPS range.

# Settings Recommendations

For 4K gaming, High settings at 64.7 FPS is the recommended preset. It provides a 4.0 FPS margin over the 60 FPS playability line, and the visual improvement over Medium (86.1 FPS) is worth the 21.4 FPS cost, since the latter still exceeds 60 FPS but with reduced detail. Ultra at 60.7 FPS is technically playable but leaves no headroom for drops, making it risky for action sequences.

At 1440p, Ultra settings at 105.6 FPS is the clear choice. It delivers a high frame rate with maximum visual quality, and the gap to High (111.6 FPS) is only 6.0 FPS, so the extra detail is essentially free. If targeting 144 Hz, Medium (141.8 FPS) is the minimum preset needed, as High falls below that threshold.

At 1080p, Ultra at 149.3 FPS is the best experience for most users, as it exceeds 144 Hz. For 240 Hz displays, Medium (205.4 FPS) or Low (232.1 FPS) are required, but the visual sacrifice at Low may not be worth the 26.7 FPS gain over Medium. High at 161.9 FPS is a middle ground for 165 Hz monitors.

Overall, the data suggests prioritizing resolution over settings: 1440p Ultra (105.6 FPS) provides a better experience than 4K Medium (86.1 FPS) for most players. The 4K High setting (64.7 FPS) is viable but not ideal for fast-paced stealth gameplay where frame consistency matters.

# Measured FPS Breakdown

At 1920x1080, the measured average FPS by preset is: Low 232.1, Medium 205.4, High 161.9, Ultra 149.3. The step from Low to Medium costs 26.7 FPS, from Medium to High costs 43.5 FPS, and from High to Ultra costs 12.6 FPS. The largest relative drop occurs between Medium and High (21.2% decrease).

At 2560x1440, the averages are: Low 187.3, Medium 141.8, High 111.6, Ultra 105.6. The drop from Low to Medium is 45.5 FPS (24.3%), Medium to High is 30.2 FPS (21.3%), and High to Ultra is 6.0 FPS (5.4%). The diminishing returns from High to Ultra are evident.

At 3840x2160, the averages are: Low 112.2, Medium 86.1, High 64.7, Ultra 60.7. The drop from Low to Medium is 26.1 FPS (23.3%), Medium to High is 21.4 FPS (24.9%), and High to Ultra is 4.0 FPS (6.2%). At 4K, the Ultra preset barely outperforms High, with only a 4.0 FPS difference.

Cross-resolution analysis shows that 1080p Low (232.1) is 2.1x faster than 4K Low (112.2), while 1080p Ultra (149.3) is 2.5x faster than 4K Ultra (60.7). The scaling is consistent with pixel count increases: 4K has 4x the pixels of 1080p, but the FPS does not drop by 4x, indicating some CPU headroom at lower settings.

# CPU Role

The Intel Core i9-14900K has 24 cores and 32 threads, with a base clock of 3.20 GHz and a boost clock of 6.00 GHz. Its architecture is Raptor Lake-R on a 10 nm process, with 36 MB of shared L3 cache and 2 MB of L2 per core. For Thief, this CPU is vastly overqualified, as the game's 2014 release predates multi-core optimization common in modern titles.

The CPU's benchmark scores confirm its strength: Cinebench R23 multi-core scores 49,872 and single-core 7,040, while Geekbench multi-core is 20,370 and single-core 3,064. The PassMark multi-thread score is 58,674, with a single-thread score of 4,697. The CPU's percentile rank is 97 among all CPUs, placing it in the top 3% of processors.

In Thief, the CPU's role is likely limited to physics, AI, and scene management. The measured FPS at 1080p Low (232.1) suggests the CPU can feed the GPU well beyond typical display refresh rates. Even at 4K Low (112.2), the CPU is not the bottleneck, as the GPU is fully utilized at this resolution.

The nearest rivals to the i9-14900K include the AMD EPYC 7413 (avg score 80,041, delta -0.3%), the Core i9-14900KF (79,245, +0.7%), and the Core Ultra 7 265KF (79,240, +0.7%). The i9-14900K's avg benchmark score is 79,824, which is within 0.3% of the EPYC 7413 and 0.7% of the 14900KF. This tight grouping shows the CPU is not the differentiating factor in Thief's performance.

# How This Combo Ranks

The combination of the Intel Core i9-14900K and NVIDIA GeForce RTX 5070 ranks 126th out of 1,642 tested combos in Thief, placing it in the top 7.7% of all configurations. This is a strong showing for a game that is over a decade old, but the rank reflects the GPU's mid-to-high tier position more than the CPU's top-tier status.

The GPU's percentile rank of 83 (avg score 41,687) is notably lower than the CPU's 97th percentile, indicating the RTX 5070 is the weaker component in this pairing. The GPU's nearest rivals in synthetic benchmarks include the Radeon Pro 5300 (41,610, +0.2%), Tesla M40 (41,897, -0.5%), and RTX 3090 (41,441, +0.6%). The RTX 5070's score is within 0.7% of these competitors, showing it is not a dominant GPU.

In Thief specifically, the combo's rank of 126 suggests it beats 1,516 other configurations. This is likely because the game is GPU-bound at higher resolutions, and the RTX 5070's 12 GB VRAM and 672.0 GB/s bandwidth are sufficient for the game's textures. The CPU's high single-thread performance (7,040 in Cinebench R23 single-core) also helps in a game that may rely on fewer cores.

The rank could be higher if paired with a stronger GPU, such as those in the top 10% of GPUs, but the data shows this combo is well-balanced for Thief. The 4K High result (64.7 FPS) is respectable, and the 1080p Ultra result (149.3 FPS) is excellent for high-refresh gaming. Overall, the combo delivers a playable experience at all resolutions and settings, with the caveat that 4K Ultra (60.7 FPS) is marginal.
