Thief

The Intel Core i7-14700K paired with an AMD Radeon RX 6600 delivers a curious mix of high ceiling and low floor in Thief. The 20-core, 28-thread CPU (base 3.40 GHz, boost 5.60 GHz) is decisively a top-tier processor, yet the 8 GB Radeon RX 6600 (boost 2491 MHz, 224.0 GB/s bandwidth) holds the combo back at higher resolutions. Measured data shows the pair falls to 32–33 FPS at 4K Ultra/High while reaching 142 FPS at 1080p Low—the GPU’s bandwidth and pixel rate dictate the overall curve. This report dissects how the resolution scaling, GPU and CPU contributions, and the combo’s rank in the Thief benchmark show a system that excels only when pixel requirements stay low.

Resolution Scaling

The frame-rate degradation from 1080p to 4K is steep and consistent across every preset. At Low settings, the average FPS goes from 142 at 1920×1080 to 98 at 2560×1440 to 57 at 3840×2160. This means a 59% loss going from 1080p to 4K at Low. At Medium, the drop is from 108 → 74 → 44 (59% loss). High goes 82 → 56 → 33 (60% loss). Ultra goes 78 → 54 → 32 (59% loss). The uniformity of the drop—approximately 60% across all presets—indicates the pixel count, not shader complexity, is the dominant variable. The pixel rate of the GPU is 159.4 GPixel/s; at 4K (8.3 million pixels) the GPU must process over a billion pixels per second to sustain 60 FPS, which it simply cannot do; the measured numbers align with a full rasterization limit.

The scaling pattern also reveals when the CPU no longer matters. At 1080p Low, the combo achieves 142 FPS, likely limited by the GPU’s ability to saturate the CPU’s IPC. At 1440p and 4K, the FPS curve flattens as the GPU takes full responsibility—for example, moving from 1440p Low to 4K Low costs only 41 FPS but relative drop of 42%. The lack of min/max data for most presets (only Medium shows min 37 max 50 at 4K) suggests that frame pacing is consistent enough to report only an average, but the 32–33 FPS at 4K Ultra/High indicates a stuttering experience.

GPU Role

The AMD Radeon RX 6600 is a mid-range card from 2021, with 8GB of GDDR6 memory across a 128-bit bus. Its bandwidth of 224.0 GB/s is adequate for Thief’s 2014-era textures, but its compute power (1792 shading units, 112 TMUs, 64 ROPs) is the bottleneck. The GPU’s clocks—base 1626 MHz, boost 2491 MHz, game 2044 MHz—determine its fill rate. At 1080p, these clocks deliver over 140 FPS at Low, but at 4K, the frame rate cannot manage even 60 FPS at Low. The GPU’s DirectX 12 Ultimate support (the card is RDNA 2 with 28 RT cores) is irrelevant in Thief since it doesn't use ray acceleration.

The GPU’s benchmark percentile (63rd) and its average score of 19036 place it close to the NVIDIA Quadro K6000 (avgScore 19030, deltaPct 0) and the RTX 4050 Mobile (19049, -0.1%). These near-identical competition numbers show the RX 6600 is not an exceptional performer; the high CPU pairing cannot boost it beyond a GPU-bound wall. The fact that the GPU’s 8GB VRAM is never a limiting factor in this title is clear from the 33 FPS at 4K Ultra—if memory pressure were the bottleneck, the drop would be intermittent; instead, consistent low FPS confirms raster limits.

The GPU’s silicon has an 11,060-million transistor count on a 237 mm² die, process 7 nm. However, the GPU’s pixel rate (159.4 GPixel/s) and texture rate (279.0 GTexel/s) are the actual constraints. For reference, at 4K the required pixel fill is 8.3 M pixels per frame; at 32 FPS, that’s 265 M pixels per second, which is above the 159.4 GPixel/s peak—yet the GPU still hits 32 FPS, meaning that the game is utilising a fraction of the theoretical fill. This discrepancy may indicate a shader-bound bottleneck rather than fill rate, but the numbers show that GPU hardware limits page at 4K.

The GPU’s launch MSRP is 329 USD, though we note that only once.

How This Combo Ranks

In the Thief benchmark, the Intel Core i7-14700K and RX 6600 receive a combined rank of 2892 out of 3720 tested combos. This places at the 22nd percentile—only 21.4% of tested configurations perform worse than this pair. The rank is low because the GPU is a midrange card, while the CPU is a high-end desktop processor (94th percentile among all CPUs in average benchmark score). A powerful CPU cannot rescue a low-end GPU when the game is shader-limited, as Thief is for both resolutions. The ranking says a lot: the combination’s overall score is dragged down by the GPU’s pixel capacity, not the CPU’s threading width (20 cores and 28 threads). The i7-14700K’s average benchmark score is 69355, beating its nearest rivals—AMD EPYC 9115 (avgScore 69288, +0.1%), Ryzen 9 7950X (69515, -0.2%)—but those numbers don’t translate to FPS in this title.

The hard rank also suggests that if a user needs to improve performance, upgrading the GPU is the highest priority. The CPU will easily handle any faster GPU, but the reverse is not true.

FAQ

*Q: Does the RX 6600 ever run out of VRAM in Thief?*

A: No. The 8 GB of GDDR6 is sufficient for Thief at all resolutions. Even at 4K Ultra, the lowest FPS is 32, which is a result of GPU processing power, not VRAM. The game’s memory footprint is modest; a 2014 title cannot fill 8 GB.

Q: How much faster is 1080p Low than 4K Low?

A: The average FPS at 1080p Low is 142, while at 4K Low it is 57. That is a 85 FPS difference, indicating a 49% reduction in performance when moving to 4K.

Q: Which resolution provides a guaranteed 60+ FPS at High settings?

A: Only 1080p with High settings reaches 60+: the average is 82 FPS. At 1440p High, the average is 56, which is slightly below 60. At 4K, no preset achieves 60.

Q: Is the i7-14700K a bottleneck for the RX 6600 in this game?

A: At 1080p, the CPU can deliver 142 FPS at Low, and for most settings the FPS is limited by the GPU. The CPU’s boost of 5.60 GHz and high single-thread geekbench score (2569) are more than enough; no scenario shows a CPU-limited issue, since the drop in FPS from 1080p to 4K correlates with resolution rather than CPU load.

*Q: How does on Thief opt for a CPU, how does the i7-14700K’s neighbor compare?*

A: In the Cinebench R23 multicore, the i7-14700K scores 33440.5, and in single-core 2160. This far outlies any game load a 2014 title might impose. The CPU’s percentile of 94 means it beats 94% of all CPUs, but in Thief, the combo rank is low because of the GPU.

Q: What is the maximum measurable frame rate in the dataset?

A: The highest average FPS is 142, observed at 1920×1080 with Low settings. No other preset exceeds this.

• 2560×1440 Medium: avg 74, min 63, max 85
• 3840×2160 Medium: avg 44, min 37, max 50
• 1920×1080 High: avg 82 FPS (no min/max)
• 2560×1440 High: avg 56 FPS (no min/max)
• 3840×2160 High: avg 33 FPS (no min/max)
• 1920×1080 Ultra: avg 78 FPS (no min/max)
• 2560×1440 Ultra: avg 54 FPS (no min/max)
• 3840×2160 Ultra: avg 32 FPS (no min/max)

This data also shows that Medium has the only recorded min/max values, suggesting a more varied frame sequence there—likely due to scene complexity. At 1080p, the gap between Low and Medium is 142→108, while between Medium and High is 108→82, a 24% drop. At 1440p, the variance is smaller (98→74→56→54) — the higher resolutions compress the quality impact.

CPU Role

The Intel Core i7-14700K provides then i7’s Raptor Lake architecture with 20 cores / 28 threads, a base of 3.40 GHz and a boost of 5.60 GHz. Its L3 cache of 33 MB shared, a M20 core 257 mm², and a 10 nm process. Its single-core Geekbench result (2569) and multicore (20767) are far above what any 2014 game, with a TDP of 125 W, can reproduce. However, the CPU’s strength in Thief is overshadowed by the GPU. At 1080p Low, the system reaches 142 FPS, which consumed a huge amount of compute at boost, but even at Ultra (78 FPS) the CPU is likely not fully taxed. The CPU’s score in Cinebench R20 multi-core 18544 and single 2617 gives it near Head of the head for a CPU.

The i7-14700K’s nearest rivals in synthetic benchmarks include AMD Ryzen 9 7950X (avgScore 69515, deltaPct -0.2%), Ryzen 9 7940HX (69875, -0.7%), and Ryzen 7 9700F (69996, -0.9%). All three are within 1% of its aggregate score, yet none change the fact that Thief will be GPU-bound. The CPU’s ability to handle simple instructions is irrelevant; its raw clock speed (5.60 GHz) is among the highest of any, but the frame times are dominated by the GPU shader loops. The absence of RT cores or their use in this game—turn to CPU of course.

The CPU socket is LGA1700, launches with a $409 launch MSRP (once). The CPU’s ECC support and dual-channel DDR4/DDR5 need no attention. The CPU is everything end, but the GPU’s 8 GB VRAM is the only thing that hits a wall.

Settings Recommendations

Given the measured data, the optimal preset to achieve a balance between visual fidelity and playable FPS is 1920×1080 Ultra. At that setting the average is 78 FPS, which is comfortably above the 60 FPS threshold and 4% drops from 82 FPS at High—a negligible cost. For 1440p displays, the best is Medium with 74 FPS, whereas High and Ultra slip to 56 and 54 respectively. The Low preset at 1440p (98 FPS) is too visually reductive for a 2014 title that already shows its age.

For 4K, the harsh reality is that only Low yields 57 FPS, which is margin-of-error under 60 and subject to drops (the Medium values show 37 min). If 60+ FPS is a hard requirement, a 4K resolution must be avoided altogether with this GPU; instead, 1440p High at 56 FPS offers a visual upgrade over 1080p Ultra but sacrifices the 22% speed a 1080p display would give. Since the mean FPS at 1440p High is 56, the GPU’s overhead is limited, but a price for quality.

The Medium preset at 1440p (74 FPS) is the sweet spot: it beats the 60 FPS target while retaining more effect detail than Low. The 1080p Medium 113 FPS leaves headroom but Ultra is nearly as fast and looks better. In conclusion, 1080p Ultra (78 FPS) is the best pairing of visual quality and frame rate, while 1440p Medium is the strongest compromise for 1440p users. The 4K experience is only playable at Low (57 FPS) and even then it’s borderline.

Overall, this benchmark group highlights that the i7-14700K’s raw computational power is opious, but the RX 6600 lacks electrical trace to support anything above 1080p. The user’s hardware will work best at that resolution; otherwise the GPU must be upgraded to reach 1440p at high dramas.
