Thief

The Intel Core i5-13400F paired with the AMD Radeon RX 6600 delivers a playable but not flawless experience in Thief, with the data showing a clear progression from a smooth 1080p experience to a demanding 4K workload. The measured frames per second (FPS) reveal that the combination operates within a wide performance envelope, and the bottleneck shifts depending on the resolution and quality preset selected.

Resolution Scaling

The FPS data shows a steep performance curve as resolution climbs. At 1920x1080 with Low settings, the combo achieves 144.3 FPS, which drops to 85.2 FPS at High and 77.2 FPS at Ultra. Moving to 2560x1440, the average at High falls to 58.1 FPS, while Ultra dips to 54.4 FPS. At 4K (3840x2160), the strain becomes evident: High settings yield just 31.3 FPS, and Ultra drops further to 35.2 FPS, which is counterintuitive but indicates that the Ultra preset may not scale uniformly with resolution in this title.

The 4K results tell a clear story about the limiting component. At 4K High, the frame rate is 31.3 FPS, while at 4K Low it jumps to 57.1 FPS. This 25.8 FPS difference between Low and High at the same resolution suggests the GPU is heavily taxed by the higher-quality rendering settings. In contrast, at 1080p the gap between Low (144.3 FPS) and High (85.2 FPS) is 59.1 FPS, which shows that the GPU has more headroom at lower resolutions. The scaling pattern indicates that the AMD Radeon RX 6600’s memory bandwidth and shading capabilities are the primary constraints at 4K, while at 1080p the processor can feed frames fast enough to expose the GPU’s limits.

The delta between 1440p and 4K is particularly telling. At High settings, 1440p delivers 58.1 FPS, but 4K only manages 31.3 FPS — a 46% reduction in performance. This is a classic sign of a GPU-bound scenario, as the pixel throughput requirement at 4K outstrips what the RX 6600 can sustain. At Low settings, the drop from 1440p (98 FPS) to 4K (57.1 FPS) is less severe at 42%, but still substantial. The data suggests that for consistent 60 FPS gameplay, 1440p High is the practical ceiling for this combo.

CPU Role

The Intel Core i5-13400F brings a 10-core, 16-thread configuration with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. Its architecture, Raptor Lake, is built on Intel’s 10 nm process. In synthetic benchmarks, the CPU posts a Cinebench R23 multi-core score of 21279 and a single-core score of 3004, while Geekbench multi-core reaches 10971 and single-core 2301. These numbers indicate strong multi-threaded throughput, but Thief is a 2014 title that predates the widespread use of many-core processors.

Looking at the FPS data, the CPU’s role appears secondary to the GPU at higher resolutions. At 1080p Low, the combo hits 144.3 FPS, which is likely near the engine’s frame rate ceiling or the GPU’s rasterization limit. The CPU’s single-core performance, as measured by 3dmark_single_thread at 960, is sufficient to keep up with the game’s logic at these frame rates. However, the passmark_physics score of 1437 suggests that physics-heavy scenes could introduce CPU bottlenecks, though the measured FPS data does not include minimum frame rates to confirm this.

The 3dmark_16_threads score of 7314 and 3dmark_max_threads at 7307 show that the CPU scales well with thread count, but Thief’s engine likely does not utilize all 16 threads efficiently. The boost clock of 4.60 GHz provides the single-threaded headroom needed for older games that rely on a few fast cores. In this context, the i5-13400F is not the limiting factor at 4K, where the GPU is clearly saturated, but at 1080p Low, the CPU’s fast boost clock helps maintain high frame rates. The CPU’s 65 W TDP also means it runs cool, but that’s a thermal characteristic, not a performance metric.

FAQ

*Q: What is the best resolution for playing Thief with this combo?*

A: The data shows that 2560x1440 at High settings delivers 58.1 FPS, which is close to the 60 FPS target. At 1920x1080, High settings reach 85.2 FPS, providing a more comfortable margin above 60 FPS.

*Q: Does the GPU or CPU bottleneck this system in Thief?*

A: At 4K, the GPU is the clear bottleneck, as evidenced by the drop from 57.1 FPS at Low to 31.3 FPS at High. At 1080p, the CPU’s boost clock of 4.60 GHz helps push frame rates to 144.3 FPS at Low, indicating the GPU becomes the limiting factor at higher settings.

Q: How does the RX 6600 compare to its nearest rivals in synthetic benchmarks?

A: The RX 6600 has an average benchmark score of 25235, which is nearly identical to the AMD Radeon 890M (25246, deltaPct 0) and the AMD Radeon RX 580 2048SP (25287, deltaPct -0.2). It is slightly ahead of the NVIDIA GeForce RTX 3060 Ti (25120, deltaPct 0.5) by 0.5%.

Q: What is the performance difference between Low and Ultra settings at 1440p?

A: At 2560x1440, Low settings yield 98 FPS, while Ultra settings drop to 54.4 FPS. This 43.6 FPS difference highlights the significant impact of quality presets on this GPU.

Q: Is the i5-13400F a strong performer relative to other CPUs?

A: The CPU holds an 82nd percentile ranking among all CPUs, with an average benchmark score of 25236. Its nearest rival, the Intel Core i7-13620H, scores 25201, a delta of 0.1%, while the AMD Ryzen 5 5600X3D scores 25365, a delta of -0.5%.

*Q: Can this combo handle 4K gaming in Thief?*

A: At 4K High, the average FPS is 31.3, and at Ultra it is 35.2. These numbers are below the 60 FPS target, so 4K is only playable at Low settings, where the combo reaches 57.1 FPS.

How This Combo Ranks

In the database of tested combinations for Thief, this pairing of the Intel Core i5-13400F and AMD Radeon RX 6600 ranks 1314 out of 1642 combos. This places it in the lower third of all tested configurations, which is consistent with the measured FPS data showing that it struggles at 4K and only achieves solid performance at 1440p and below. The rank reflects the overall average FPS across all tested resolutions and settings, and the data indicates that many other combinations deliver higher frame rates in this title.

The ranking is not surprising given the RX 6600’s position in the GPU hierarchy. With a percentile ranking of 69 among all GPUs, the card is mid-range, and its average benchmark score of 25235 places it just above the AMD Radeon RX 580 2048SP. The CPU, however, ranks higher at the 82nd percentile, suggesting that the processor is not the limiting factor in this pairing. The combo’s rank of 1314 out of 1642 implies that users seeking higher frame rates in Thief would need a stronger GPU, while the i5-13400F provides adequate headroom for future upgrades.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture with a Navi 23 chip, manufactured on TSMC’s 7 nm process. It features 8 GB of GDDR6 memory on a 128-bit bus, providing 224.0 GB/s of bandwidth. The GPU’s boost clock is 2491 MHz, with a game clock of 2044 MHz, and it houses 1792 shading units, 112 texture mapping units, and 64 raster operations units. Its FP32 performance is rated at 8.928 TFLOPS.

In Thief, the GPU’s role is dominant at higher resolutions. The 4K High result of 31.3 FPS versus 4K Low’s 57.1 FPS demonstrates how the card’s pixel rate of 159.4 GPixel/s and texture rate of 279.0 GTexel/s are overwhelmed by the combination of high resolution and quality settings. The 8 GB VRAM is likely sufficient for this 2014 game, but the bandwidth of 224.0 GB/s becomes a constraint at 4K. At 1080p, the GPU’s boost clock of 2491 MHz helps achieve 144.3 FPS at Low settings, showing that the card can stretch its legs when the resolution is lower.

The GPU’s average benchmark score of 25235 places it just 0.5% ahead of the NVIDIA GeForce RTX 3060 Ti (25120), but its performance in Thief is more nuanced. The measured FPS at 1440p High (58.1 FPS) and 1080p Ultra (77.2 FPS) suggests the card is well-suited for 1080p and entry-level 1440p gaming, but the 4K results confirm it is not a 4K solution for this title. The GPU’s DirectX 12 Ultimate support and Vulkan 1.4 API compatibility are forward-looking, but Thief likely uses older DirectX features, which the card handles with ease at lower resolutions.
