Thief

The Intel Core i5-13400F paired with the AMD Radeon RX 6800 XT ranks 461st out of 1,642 tested combinations in Thief, placing it in the top 28% of all systems. This is a strong position, though not an elite one, suggesting the pairing is well-balanced for this 2014 stealth title but leaves headroom for higher-end configurations. The combo's percentile placement indicates that while it outperforms the majority of tested systems, there are still 460 combinations ahead of it, likely featuring newer GPUs or higher-core-count CPUs. The data shows this pairing sits comfortably in the upper-middle tier, offering a consistent experience across the board.

How This Combo Ranks

The combo's rank of 461 out of 1,642 places it in the 72nd percentile, meaning it outperforms roughly 72% of all tested combinations in Thief. This is a respectable showing for a mid-range CPU paired with a high-end GPU from the previous generation. The ranking suggests that the i5-13400F does not bottleneck the RX 6800 XT in this title, as the pair achieves frame rates that would satisfy most players. However, the gap to the top-tier combos is notable; the data implies that systems ranked higher likely feature GPUs with stronger raw throughput or additional VRAM bandwidth, which Thief can leverage at higher resolutions. The i5-13400F's 82nd percentile ranking among all CPUs and the RX 6800 XT's 87th percentile among all GPUs indicate both components are individually above average, yet their combined performance in Thief lands slightly below what their individual scores might suggest, hinting at a minor software-level inefficiency or a game engine quirk.

GPU Role

The Radeon RX 6800 XT brings 16 GB of GDDR6 memory on a 256-bit bus, delivering 512.0 GB/s of bandwidth. With a base clock of 1825 MHz, a game clock of 2015 MHz, and a boost clock of 2250 MHz, this GPU has substantial headroom for sustained loads. In Thief, the GPU's 20.74 TFLOPS of FP32 compute is the primary driver of frame rates, especially at higher settings where pixel and texture rates become critical. The card's 288.0 GPixel/s pixel rate and 648.0 GTexel/s texture rate are more than sufficient for a game from 2014, which explains why even at Ultra settings at 4K, the average FPS stays above 50. The GPU's 87th percentile ranking among all GPUs, with an average benchmark score of 49,982, places it just ahead of the NVIDIA RTX 4070 Ti SUPER (2.6% delta) and behind the NVIDIA RTX A1000 (-1.7% delta). This positioning suggests the RX 6800 XT is a capable 4K performer for older titles, though the data shows its dominance wanes as resolution increases, which is expected given the fixed memory bandwidth.

Resolution Scaling

The measured FPS data reveals a clear pattern of diminishing returns as resolution increases. At 1080p with Low settings, the combo achieves 176.6 FPS, which drops to 160.3 FPS at 1440p and further to 96.2 FPS at 4K. This represents a 45.5% drop from 1080p to 4K at Low settings, indicating that the GPU becomes the limiting factor at higher resolutions. At Ultra settings, the drop is more pronounced: 128.3 FPS at 1080p falls to 91.8 FPS at 1440p (a 28.5% decrease) and then to 50.9 FPS at 4K (a 60.3% decrease from 1080p). This steep decline at 4K Ultra suggests the RX 6800 XT's 16 GB VRAM and 512.0 GB/s bandwidth are being taxed heavily by the combination of high resolution and maximum settings. The data implies that at 1080p and 1440p, the CPU has more influence on frame rates, while at 4K, the GPU's raw throughput dominates. The scaling from 1080p to 1440p is relatively mild across all settings, but the jump to 4K introduces a significant penalty, particularly at Ultra where the frame rate nearly halves.

Measured FPS Breakdown

At 1920x1080, the combo delivers 176.6 FPS on Low, 159.7 FPS on Medium, 134.2 FPS on High, and 128.3 FPS on Ultra. The gap between Low and Ultra is 48.3 FPS, showing that settings have a moderate impact at this resolution. Moving to 2560x1440, the numbers are 160.3 FPS on Low, 126 FPS on Medium, 96.3 FPS on High, and 91.8 FPS on Ultra. Here, the spread between Low and Ultra widens to 68.5 FPS, indicating that the GPU starts to feel the pressure. At 3840x2160, the story changes dramatically: Low yields 96.2 FPS, Medium 74.4 FPS, High 57 FPS, and Ultra 50.9 FPS. The Ultra setting at 4K is the only configuration that dips below 60 FPS, which is a critical threshold for smooth gameplay. The data shows that at 1080p and 1440p, even Ultra settings remain playable, but at 4K, players must drop to High or lower to maintain a consistent frame rate. Interestingly, the difference between High and Ultra at 1440p is only 4.5 FPS, suggesting that Ultra's additional effects provide diminishing returns at this resolution.

Settings Recommendations

For players targeting 60 FPS or higher, the data clearly indicates that 4K Ultra is not viable, as it averages just 50.9 FPS. Dropping to 4K High brings the average to 57 FPS, which is still borderline, while 4K Medium offers a comfortable 74.4 FPS. At 1440p, all settings exceed 90 FPS, with Ultra at 91.8 FPS and High at 96.3 FPS, making either a solid choice. For 1080p, even Ultra maintains 128.3 FPS, so there is no need to compromise on settings. The most balanced experience per the measured rows is 1440p High, which delivers 96.3 FPS with a 73.3% of the maximum frame rate seen at 1080p Low (176.6 FPS). This setting provides a good visual quality-to-performance ratio without pushing the GPU to its limits. Alternatively, 4K Medium at 74.4 FPS offers a substantial resolution upgrade over 1440p Ultra (91.8 FPS) with only a 17.4 FPS penalty, making it an attractive option for players with 4K displays who prioritize resolution over maximum settings. The data suggests that the sweet spot for this combo is either 1440p Ultra or 4K Medium, depending on whether the user prefers higher resolution or higher visual fidelity.

CPU Role

The Intel Core i5-13400F features 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. Its 20 MB of shared L3 cache and dual-channel memory support (DDR4 and DDR5) provide ample bandwidth for gaming workloads. In Thief, the CPU's single-thread performance is crucial, and the data shows a 3dmark_single_thread score of 960 and a passmark_single_thread score of 3,634, which are solid but not exceptional. The CPU's 82nd percentile ranking among all CPUs, with an average benchmark score of 25,236, places it virtually tied with the Intel Core i7-13620H (0.1% delta) and the AMD Ryzen 5 5600X3D (-0.5% delta). This indicates that the i5-13400F is a well-rounded performer that does not hold back the RX 6800 XT in most scenarios. However, the measured FPS scaling from 1080p to 4K suggests that the CPU's influence diminishes at higher resolutions, as the GPU becomes the bottleneck. The 3dmark_16_threads score of 7,314 and cinebench_r23_multicore score of 21,279 show strong multi-threaded capability, which helps in maintaining consistent frame times in Thief's open-world environments. The data implies that the i5-13400F provides enough processing power to keep up with the GPU at 1080p and 1440p, but at 4K, the GPU's limits are the primary constraint.

FAQ

Q: What is the best resolution for this combo in Thief?

A: The data shows that 1440p delivers the most balanced experience, with all settings exceeding 90 FPS. At 1080p, even Ultra reaches 128.3 FPS, while 4K requires dropping to Medium or Low to stay above 60 FPS.

Q: Can this combo run Thief at 4K with maximum settings?

A: No. The measured FPS at 4K Ultra averages 50.9 FPS, which falls below the 60 FPS threshold. To achieve a smooth 4K experience, the data suggests using Medium settings, which yield 74.4 FPS.

Q: How does the CPU compare to its nearest rivals?

A: The i5-13400F's average benchmark score of 25,236 is within 0.5% of the AMD Ryzen 5 5600X3D and 0.1% of the Intel Core i7-13620H, indicating near-identical performance in synthetic benchmarks.

Q: What is the GPU's VRAM and bandwidth, and does it matter for Thief?

A: The RX 6800 XT has 16 GB of GDDR6 memory with 512.0 GB/s bandwidth. In Thief, this is more than sufficient, as the game's 2014 engine does not heavily tax VRAM, even at 4K Ultra.

Q: What is the frame rate difference between High and Ultra settings at 1440p?

A: At 1440p, High averages 96.3 FPS while Ultra averages 91.8 FPS, a difference of only 4.5 FPS. This suggests that Ultra does not offer significant visual improvements for the performance cost at this resolution.

Q: Is the GPU or CPU the limiting factor at 1080p?

A: At 1080p, the CPU's influence is more apparent, as the frame rates across settings (128.3 FPS to 176.6 FPS) suggest that the GPU has headroom. The i5-13400F's single-thread score of 960 (3dmark) indicates it can keep up, but the data shows that lowering settings from Ultra to Low increases FPS by 48.3, implying the GPU still plays a role even at this resolution.
