Thief

The Intel Core Ultra 7 270K Plus paired with the AMD Radeon RX 580 produces a playable but constrained experience in Thief, a 2014 stealth title. The benchmark data shows a system where the GPU is the primary bottleneck, especially at higher resolutions, while the CPU’s substantial core and thread count goes largely underutilized. The measured frame rates reveal a clear hierarchy of settings and resolutions, with the sweet spot at 1080p Medium, which delivers a solid 63 FPS average. This analysis breaks down the measured FPS data, settings recommendations, and the roles each component plays in shaping the final performance.

Settings Recommendations

The measured FPS rows provide a clear picture of how Thief responds to different quality presets on this hardware combination. At 1920x1080, the Low preset delivers an average of 83 FPS, which is the highest frame rate recorded in the entire dataset. This makes it the only setting that comfortably exceeds the 60 FPS threshold for smooth gameplay. However, the Medium preset at the same resolution produces a 63 FPS average, which is still above the 60 FPS mark and offers a significantly better visual experience than Low. The Medium preset’s minimum FPS of 54 also indicates that while there are brief dips below 60, the overall performance remains acceptable for a stealth title where precise timing matters less than in a competitive shooter. The High preset at 1080p drops to 48 FPS, and Ultra falls to 46 FPS, both of which are below the 60 FPS target and represent a noticeable step down in fluidity.

At 2560x1440, the situation becomes more challenging. The Low preset averages 57 FPS, which is just shy of the 60 FPS target, while Medium drops to 43 FPS, and High and Ultra fall to 33 and 31 FPS respectively. The 1440p Medium result is particularly telling, as the minimum FPS of 37 shows that frame pacing can become erratic. For the best balance between visual quality and playability, the 1080p Medium preset is the recommended choice. It provides a 63 FPS average, which is 31% higher than the 1080p High preset’s 48 FPS, and it maintains a minimum of 54 FPS, ensuring that the game rarely stutters. The jump from Low to Medium at 1080p costs 20 FPS on average, but the visual uplift from improved textures, shadows, and effects is substantial in a game like Thief where atmosphere and lighting are central to the experience. Pushing to High or Ultra at 1080p yields only marginal visual gains over Medium while sacrificing 15 and 17 FPS respectively, making those presets less attractive. At 1440p, the Low preset is the only viable option for near-60 FPS gameplay, but the visual compromise is steep. For players with a 1440p display, the data suggests that accepting the Low preset’s 57 FPS average is the only way to maintain fluidity, but the 1080p Medium experience is superior in both performance and fidelity. The 4K results are uniformly poor, with the best average being 33 FPS at Low, so no settings recommendation can salvage that resolution for this combo.

GPU Role

The AMD Radeon RX 580 is the defining component in this pairing, and its specifications directly explain the measured performance. The GPU features 8 GB of GDDR5 memory on a 256-bit bus, providing a memory bandwidth of 256.0 GB/s. The memory clock runs at 2000 MHz, which translates to 8 Gbps effective. This memory configuration is adequate for a 2014 title, but the GPU’s compute capabilities are more limited. The RX 580 has 2304 shading units, 144 texture mapping units, and 32 raster operation units. Its base clock is 1257 MHz, with a boost clock of 1340 MHz. This results in a pixel rate of 42.88 GPixel/s and a texture rate of 193.0 GTexel/s. The FP32 performance is rated at 6.175 TFLOPS. These numbers place the RX 580 in the 53rd percentile of all GPUs according to the benchmark data, indicating it is a mid-range part that is now several generations old.

The GPU’s impact on Thief is evident in the frame rate scaling. At 1080p, the RX 580 can push between 46 and 83 FPS depending on the preset, which shows that it has enough raw throughput for this older game at lower resolutions. The 8 GB VRAM is not a limiting factor here, as Thief from 2014 does not require large memory pools. However, the GPU’s compute power is the reason why 4K performance collapses. The 4K Ultra preset averages only 18 FPS, which is a 61% drop from the 1080p Ultra average of 46 FPS. This steep decline indicates that the RX 580’s shading units and texture units are overwhelmed by the 4K pixel count. The GPU’s memory bandwidth of 256.0 GB/s also becomes a constraint at higher resolutions, where the demand for texture data increases. The boost clock of 1340 MHz is modest by modern standards, and the GCN 4.0 architecture lacks the efficiency of newer designs. The RX 580’s PassMark G3D score of 8813 and its average benchmark score of 12928 place it near the NVIDIA GeForce RTX 3050 Ti Mobile, which has a deltaPct of -0.1, and the NVIDIA GeForce GTX 1660 SUPER, which is -0.4% slower. This means the RX 580 is competitive with those older GPUs, but it is far from the performance needed for high-refresh-rate or high-resolution gaming in more demanding titles. In Thief, the GPU is clearly the limiting factor, as the CPU has ample headroom to handle the game’s logic and physics.

Resolution Scaling

The measured FPS data across 1920x1080, 2560x1440, and 3840x2160 reveals how the system scales with resolution and where the bottleneck lies. At 1080p Low, the average FPS is 83. Moving to 1440p Low, the average drops to 57 FPS, which is a 31% reduction. At 4K Low, the average is 33 FPS, a further 42% drop from 1440p. This scaling pattern shows that the GPU is the limiting component, as the frame rate falls in near proportion to the increase in pixel count. The 1080p Medium preset averages 63 FPS, while 1440p Medium averages 43 FPS (a 32% drop), and 4K Medium averages 25 FPS (a 42% drop from 1440p). The High preset follows a similar trend: 48 FPS at 1080p, 33 FPS at 1440p, and 19 FPS at 4K. The Ultra preset is the most demanding, with 46 FPS at 1080p, 31 FPS at 1440p, and 18 FPS at 4K.

The percentage drops between resolutions are consistent across all settings, which indicates that the GPU’s compute and memory resources are saturated in a predictable manner. The 4K results are particularly revealing: even the Low preset at 4K (33 FPS) is slower than the Ultra preset at 1080p (46 FPS). This means that the pixel count has a greater impact on performance than the quality settings, which is a classic sign of a GPU-bound scenario. The CPU, with its 24 cores and 24 threads, is not the constraint here. If the CPU were the bottleneck, the frame rate would be more consistent across resolutions, as the CPU’s workload does not scale with pixel count. Instead, the data shows that the RX 580’s fill rate and shading capacity are the limiting factors. The 4K Medium preset’s minimum FPS of 22 and maximum of 29 also show that frame times become highly variable, which would result in noticeable stuttering. The resolution scaling data suggests that this combo is only viable at 1080p, where the GPU can maintain playable frame rates. At 1440p, the system is borderline, with only the Low preset approaching 60 FPS. At 4K, the system is not viable for gameplay, as even the lowest settings produce sub-30 FPS averages. The drop from 1080p to 1440p is roughly 30%, and the drop from 1440p to 4K is roughly 40%, which aligns with the pixel count increases of 78% and 125% respectively, confirming the GPU-bound nature of the performance.

How This Combo Ranks

The combo of the Intel Core Ultra 7 270K Plus and the AMD Radeon RX 580 ranks 2617 out of 2851 tested combinations in Thief. This places it in the bottom 8% of all tested combos, which is a poor showing for a system with a top-tier CPU and a mid-range GPU. The rank is heavily influenced by the GPU’s limitations, as the RX 580’s 53rd percentile standing among all GPUs drags down the overall combo performance. The CPU, in contrast, is in the 96th percentile among all CPUs, but its high performance does not compensate for the GPU’s deficiencies in this game. The combo rank of 2617 out of 2851 means that 234 other tested combinations are slower, but the vast majority of systems outperform this pairing. This ranking is expected given the RX 580’s age and the fact that it was released in 2017, while Thief was released in 2014. The game’s engine is not particularly demanding by modern standards, but the RX 580’s compute power is simply insufficient for high-resolution play.

The ranking also reflects the imbalance of this pairing. The Core Ultra 7 270K Plus is a next-generation processor with a boost clock of 5.50 GHz and 36 MB of L3 cache, but in Thief, its capabilities are largely wasted. The game is not multi-threaded enough to utilize 24 cores, and the GPU becomes the bottleneck at every resolution and setting. This means that the combo’s rank is essentially determined by the RX 580’s performance, which is mediocre for this title. The data shows that the RX 580’s average benchmark score of 12928 is very close to the NVIDIA GeForce RTX 3050 Ti Mobile (12940, deltaPct -0.1) and the NVIDIA GeForce GTX 1660 SUPER (12986, deltaPct -0.4). These GPUs are all in the same performance tier, and they all struggle with Thief at higher resolutions. The combo rank of 2617 out of 2851 suggests that users with this pairing will need to make significant compromises in settings and resolution to achieve playable frame rates. The ranking also implies that a more balanced CPU-GPU pairing, such as a mid-range CPU with a mid-range GPU, would likely perform better in this game, as the CPU’s extra performance does not translate into higher frame rates once the GPU is saturated.

CPU Role

The Intel Core Ultra 7 270K Plus is a formidable processor on paper, with 24 cores and 24 threads. Its base clock is 3.70 GHz, and it boosts to 5.50 GHz. The CPU has a 36 MB shared L3 cache, with 3 MB of L2 cache per core and 192 KB of L1 cache per core. It is built on a 3 nm process node and supports DDR5 memory with a dual-channel bus, providing a memory bandwidth of 115.2 GB/s. The CPU’s benchmark scores are impressive, including a Cinebench R23 multi-core score of 44253 and a single-core score of 2439. Its PassMark single-thread score is 5068, and its multithread score is 68574. These numbers place the CPU in the 96th percentile of all CPUs, and its average benchmark score of 93785 is nearly identical to the Intel Xeon 6520P (93786, deltaPct 0). The CPU’s nearest rivals include the AMD EPYC 4564P (95183, deltaPct -1.5) and the AMD EPYC 9175F (95615, deltaPct -1.9), which are server-class processors with similar performance.

In Thief, however, the CPU’s role is minimal. The measured FPS data shows that the frame rate is almost entirely dependent on the GPU, as evidenced by the consistent scaling across resolutions. The CPU’s 24 cores and 24 threads are far more than what a 2014 game can utilize. Thief was designed for the quad-core and dual-core CPUs of its era, and it relies on single-threaded performance for most of its game logic. The Core Ultra 7 270K Plus’s single-core performance is excellent, with a Cinebench R23 single-core score of 2439, but this does not translate into higher frame rates because the GPU is the limiting factor. At 1080p Low, the system averages 83 FPS, which is the highest in the dataset. This suggests that the CPU is fast enough to feed the GPU even at low settings, where the GPU’s load is lighter. However, as the resolution increases, the GPU’s load grows, and the CPU’s headroom becomes irrelevant. The CPU’s high memory bandwidth of 115.2 GB/s and support for DDR5 memory ensure that data can be fed to the GPU quickly, but this does not overcome the GPU’s compute limitations. The CPU’s boost clock of 5.50 GHz is a key factor in its strong single-threaded performance, but in Thief, the game’s engine does not push the CPU to its limits. The PassMark data compression score of 804322 and encryption score of 59097 are indicative of the CPU’s general processing power, but these are not relevant to gaming performance. In summary, the CPU is vastly overqualified for this game, and its role is to ensure that the GPU is never starved for data. The measured frame rates would be identical with a much weaker CPU, as long as that CPU could maintain a single-threaded performance above a certain threshold.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the system’s performance across all resolutions and settings. At 1920x1080, the Low preset delivers an average of 83 FPS, which is the best result in the entire dataset. The Medium preset at 1080p averages 63 FPS, with a minimum of 54 FPS and a maximum of 72 FPS. This makes it the only preset at any resolution that offers both an above-60 FPS average and a minimum FPS above 50. The High preset at 1080p averages 48 FPS, and the Ultra preset averages 46 FPS. There is only a 2 FPS difference between High and Ultra at 1080p, suggesting that the Ultra preset’s additional effects have a minimal impact on the GPU at this resolution. The 1080p results show a clear progression: Low (83 FPS) to Medium (63 FPS) is a 24% drop, Medium to High (48 FPS) is a 24% drop, and High to Ultra (46 FPS) is a 4% drop.

At 2560x1440, the Low preset averages 57 FPS, which is just below the 60 FPS target. The Medium preset averages 43 FPS, with a minimum of 37 FPS and a maximum of 50 FPS. The High preset at 1440p averages 33 FPS, and the Ultra preset averages 31 FPS. The drop from 1080p Low (83 FPS) to 1440p Low (57 FPS) is 26 FPS, or 31%. The drop from 1080p Medium (63 FPS) to 1440p Medium (43 FPS) is 20 FPS, or 32%. The High preset drops from 48 FPS at 1080p to 33 FPS at 1440p, a 31% reduction, and Ultra drops from 46 FPS to 31 FPS, a 33% reduction. These consistent percentage drops across settings confirm that the GPU is the bottleneck, as the resolution increase affects all presets equally.

At 3840x2160, the results are poor across the board. The Low preset averages 33 FPS, which is the only 4K result above 30 FPS. The Medium preset averages 25 FPS, with a minimum of 22 FPS and a maximum of 29 FPS. The High preset averages 19 FPS, and the Ultra preset averages 18 FPS. The drop from 1440p Low (57 FPS) to 4K Low (33 FPS) is 24 FPS, or 42%. The Medium preset drops from 43 FPS at 1440p to 25 FPS at 4K, a 42% reduction. High drops from 33 FPS to 19 FPS, a 42% drop, and Ultra drops from 31 FPS to 18 FPS, a 42% drop. The 4K results show that the system is not usable at this resolution, as even the Low preset produces a frame rate that is below the threshold for smooth gameplay. The Medium preset’s minimum FPS of 22 indicates that the game would stutter noticeably. The data shows that the RX 580’s 6.175 TFLOPS of FP32 performance and 256.0 GB/s of memory bandwidth are insufficient to handle the 4K pixel count, regardless of the quality settings. The only viable configurations are 1080p Low, Medium, High, and Ultra, with Medium being the recommended choice for its balance of visual quality and performance. At 1440p, only the Low preset is playable, and at 4K, no preset is playable. This breakdown of exact numbers shows the clear performance envelope of this CPU-GPU combination in Thief.
