Thief

The AMD Ryzen 5 3600 paired with the NVIDIA GeForce RTX 4070 delivers a remarkably consistent experience in Thief, with average frame rates that remain highly playable across all tested resolutions and settings. The data indicates a system that is well-balanced for this 2014 stealth title, though the performance scaling patterns reveal where the bottleneck shifts between the CPU and GPU as resolution increases.

Resolution Scaling

The measured FPS data shows that Thief is not particularly demanding on this hardware combination, but the performance drop from 1080p to 4K is substantial. At Low settings, the average frame rate falls from 123.4 FPS at 1920x1080 to 92.4 FPS at 3840x2160, a reduction of 31.0 FPS or roughly 25%. This scaling pattern suggests that even at 4K, the GPU retains significant headroom, and the CPU is not limiting performance at lower resolutions.

The gap between 1080p and 1440p is notably smaller than the gap between 1440p and 4K. At High settings, moving from 1080p to 1440p drops the average from 104.1 FPS to 93.5 FPS, a difference of 10.6 FPS. However, moving from 1440p to 4K at the same settings drops performance from 93.5 FPS to 61.3 FPS, a much steeper decline of 32.2 FPS. This indicates that the RTX 4070 begins to hit its rendering limits as pixel count increases, but the CPU is likely the limiting factor at 1080p where frame rates exceed 120 FPS.

At Ultra settings, the scaling is particularly telling. The average FPS at 1080p is 103.9, at 1440p it is 87, and at 4K it drops to 58.6. The 4K Ultra result is the only measurement below 60 FPS in the entire dataset, suggesting that this setting combination is the first to push the GPU into a region where it cannot maintain a smooth experience. The fact that 4K High (61.3 FPS) and 4K Ultra (58.6 FPS) are so close indicates that the GPU is becoming the primary constraint at this resolution, with the additional graphical load of Ultra settings having a minimal impact on the already-stressed renderer.

GPU Role

The NVIDIA GeForce RTX 4070 is built on the Ada Lovelace architecture using a 5 nm process from TSMC, with 35,800 million transistors packed into a 294 mm² die. Its memory configuration consists of 12 GB of GDDR6X on a 192-bit bus, providing 504.2 GB/s of bandwidth. The GPU operates at a base clock of 1920 MHz and boosts to 2475 MHz, with memory clocked at 1313 MHz (21 Gbps effective). These specifications place the card in the 81st percentile of all GPUs in the benchmark database, with an average benchmark score of 37283.

In Thief, the GPU's role becomes more pronounced as resolution increases. At 1080p, the RTX 4070 is capable of delivering well over 100 FPS at every settings level, which indicates that the card is not being fully utilized. The CPU-side constraints are more evident here, as the Ryzen 5 3600's performance at lower resolutions caps the frame rate. However, at 4K, the GPU's rendering load increases significantly, and the frame rates drop to the 58.6-92.4 range, demonstrating that the RTX 4070's shading units (5888) and texture mapping units (184) are being pushed harder.

The GPU's 64 ROPs and pixel rate of 158.4 GPixel/s are relevant for a game like Thief, which features a mix of indoor and outdoor environments with dynamic lighting. The 12 GB VRAM capacity is more than sufficient for this title, given its 2014 release date, and is unlikely to be a bottleneck at any of the tested settings. The RTX 4070's nearest rivals in the benchmark database include the AMD Radeon RX Vega 56 (0.6% lower average score) and the NVIDIA GeForce RTX 4080 Mobile (2.2% lower average score), which helps contextualize the GPU's overall performance tier.

How This Combo Ranks

This specific CPU-GPU combination ranks 812th out of 1642 tested combos in Thief, placing it in the upper-middle tier of the database. This rank of 812 out of 1642 means that roughly half of all tested combinations outperform it, but given the game's age and the hardware involved, this is a strong result. The Ryzen 5 3600 itself sits in the 76th percentile of all CPUs, with an average benchmark score of 18129, while the RTX 4070 is in the 81st percentile of GPUs.

The combination's rank reflects the balance between the two components. The CPU's nearest rivals include the Intel Core i5-11400 (0.1% lower average score) and the AMD Ryzen 5 7535HS (0.2% higher average score), indicating that the Ryzen 5 3600 is competitive with more modern mid-range processors. The GPU's nearest rivals include the AMD Radeon RX Vega 56 (0.6% lower) and the NVIDIA GeForce RTX 4080 Mobile (2.2% lower), showing that the RTX 4070 outperforms these alternatives in synthetic benchmarks.

In the context of Thief specifically, the combo's rank suggests that the hardware is well-matched to the game's requirements. The measured FPS data confirms this, as the system maintains playable frame rates in nearly all configurations tested. The only sub-60 FPS result is at 4K Ultra, which is an extreme setting for a game of this era. The rank of 812 out of 1642 indicates that while there are many faster combinations, this pairing delivers a smooth experience for the vast majority of players.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce an average of 123.4 FPS, Medium yields 113.8 FPS, High achieves 104.1 FPS, and Ultra reaches 103.9 FPS. The difference between High and Ultra is minimal at just 0.2 FPS, suggesting that the Ultra preset does not add significant GPU load at this resolution. The spread from Low to Ultra is 19.5 FPS, which is the smallest of any resolution, reinforcing that the CPU is the limiting factor here.

Moving to 2560x1440, the frame rates remain strong but show a clearer GPU impact. Low settings average 111.7 FPS, Medium drops to 100.3 FPS, High achieves 93.5 FPS, and Ultra reaches 87 FPS. The gap between Low and Ultra widens to 24.7 FPS, indicating that the GPU is becoming more involved in the rendering process. The 1440p results are 10-15% lower than their 1080p equivalents, which is a modest penalty for the increased resolution.

At 3840x2160, the GPU's workload becomes the dominant factor. Low settings still manage 92.4 FPS, Medium drops to 78.8 FPS, High falls to 61.3 FPS, and Ultra dips below 60 FPS to 58.6 FPS. The difference between Low and Ultra at 4K is 33.8 FPS, the largest spread in the dataset. This pattern shows that at 4K, the RTX 4070's performance scales more directly with settings, and the CPU is no longer the bottleneck. The 4K Ultra result of 58.6 FPS is the only measurement below the 60 FPS threshold, making it the least playable configuration tested.

FAQ

Q: What is the best resolution and settings combo for a smooth experience?

A: At 2560x1440 with Ultra settings, the system delivers 87 FPS on average, which is well above the 60 FPS threshold. For 4K, High settings at 61.3 FPS is the highest quality option that remains above 60 FPS, while 4K Ultra drops to 58.6 FPS.

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

A: The data indicates the CPU is the primary constraint at 1080p. The frame rates at Low (123.4 FPS) and Ultra (103.9 FPS) are close, and the overall performance is high, suggesting the Ryzen 5 3600 is capping the output rather than the RTX 4070.

Q: How much performance is lost when moving from 1080p to 4K?

A: At High settings, the average frame rate drops from 104.1 FPS at 1920x1080 to 61.3 FPS at 3840x2160, a reduction of 42.8 FPS. At Low settings, the drop is from 123.4 FPS to 92.4 FPS, a loss of 31.0 FPS.

Q: Does the RTX 4070's 12 GB VRAM cause any issues in Thief?

A: No. Given the game's 2014 release date, the 12 GB GDDR6X memory is far more than sufficient. The measured frame rates do not show any signs of VRAM-related stuttering or performance degradation at any resolution or settings level.

Q: How does this combo rank compared to all tested configurations?

A: The combination ranks 812th out of 1642 tested combos in Thief, placing it in the upper-middle tier. This rank is consistent with the CPU's 76th percentile and the GPU's 81st percentile rankings in the overall benchmark database.

Q: Is 4K Ultra playable with this hardware?

A: At 4K Ultra, the average frame rate is 58.6 FPS, which is just below the 60 FPS target. While technically playable, it is the only tested configuration that falls short of this threshold. Dropping to High settings at 4K raises the average to 61.3 FPS.
