Thief

The AMD Ryzen 7 9800X3D and NVIDIA GeForce RTX 5070 combination delivers a top-tier experience in Thief, securing the 163rd position out of 1,642 tested combos. This places the pairing comfortably within the top 10% of all system configurations evaluated for this title. The high ranking is a direct result of both components operating near their peak potential, though the measured data reveals that the GPU is the primary bottleneck at higher resolutions.

How This Combo Ranks

The combo’s rank of 163 out of 1,642 is a strong indicator of its overall capability, but it is not a reflection of raw component strength alone. Instead, it shows a well-balanced pairing for Thief’s engine. The CPU, with its 8 cores and 16 threads, posts an average benchmark score of 37,780, placing it in the 90th percentile of all CPUs. This score is virtually identical to its closest rivals, such as the Intel Xeon 6353P (deltaPct -0.1) and Intel Core Ultra 5 225 (deltaPct -0.1), indicating that the Ryzen 7 9800X3D is not leaving performance on the table in synthetic tests.

Similarly, the RTX 5070 achieves an average benchmark score of 41,687, ranking in the 83rd percentile of all GPUs. Its nearest rival, the NVIDIA GeForce RTX 3090, is a mere 0.6% behind, while the AMD Radeon Pro 5300 is 0.2% ahead. This suggests the GPU is performing exactly as expected for its class. The combination’s high in-game rank is therefore a consequence of both parts delivering their expected performance without any significant bottleneck that would drag the system down in Thief.

GPU Role

The NVIDIA GeForce RTX 5070 is built on the Blackwell 2.0 architecture and features a 12 GB GDDR7 memory buffer on a 192-bit bus, yielding a bandwidth of 672.0 GB/s. This memory configuration is adequate for Thief’s assets, even at 4K with high texture detail. The GPU’s base clock of 2325 MHz and boost clock of 2512 MHz provide the raw throughput needed to drive the game’s lighting and shadow effects.

In this benchmark, the GPU shows clear signs of being the limiting factor at 4K. The frame rate drops significantly as settings are increased, which is the classic behavior of a GPU-bound scenario. The gap between Low and Ultra settings at 3840x2160 is substantial, showing that the rendering workload is directly impacting performance. The GPU’s DirectX 11 score of 277 in Passmark is particularly relevant, as Thief relies on that API, and the strong result here confirms the card’s suitability for this specific workload.

CPU Role

The AMD Ryzen 7 9800X3D, with its Zen 5 architecture and 8 cores / 16 threads, provides a massive 96 MB of shared L3 cache. This is a critical advantage for Thief, a game that often benefits from large cache pools to feed the CPU with pre-baked geometry and AI data. The CPU’s base clock of 4.70 GHz and boost clock of 5.20 GHz are high enough to avoid holding back the GPU in most scenarios.

Synthetic benchmarks show the CPU’s strength in multi-threaded tasks, with a Cinebench R23 multi-core score of 34,004. However, the single-thread score of 4,800 is equally important for Thief, which has a strong reliance on a few primary threads for game logic. The data suggests that the CPU is not a bottleneck at 1080p, where frame rates exceed 200 FPS, but at 4K Ultra, the GPU’s workload dominates. The CPU’s percentile rank of 90th overall confirms it is a top-tier processor, but its near-identical scores to rivals like the Intel Core i9-13900HK (deltaPct -0.6) indicate that the extra cache is not yielding a massive synthetic advantage, though it likely helps with frame pacing in open-world sections.

Measured FPS Breakdown

The measured FPS data provides a clear picture of performance scaling across resolutions and settings.

At 1920x1080, the combo is exceptionally fast. The average frame rate at Low settings is 217.9 FPS, which drops to 193.3 FPS at Medium and 158.4 FPS at High. At Ultra settings, the average is 148.6 FPS. This shows that even at the highest settings, the system provides a smooth, high-refresh-rate experience that exceeds the refresh rate of most monitors.

Moving to 2560x1440, the performance remains high. Low settings yield 187.3 FPS, Medium 142 FPS, and High 109.1 FPS. Ultra settings produce 102.8 FPS, which is still above the 100 FPS threshold for fluid gameplay. The drop from 1080p to 1440p is significant but expected, with the GPU starting to feel the pressure of the increased pixel count.

At 3840x2160, the GPU becomes the clear limiting factor. Low settings produce 109.8 FPS, but this falls to 83.3 FPS at Medium and 64.2 FPS at High. Ultra settings drop the average to 60.3 FPS. This is a playable frame rate for a single-player stealth title, but it highlights that 4K Ultra is the edge of this combo’s capabilities.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals the nature of the bottleneck in this system. At 1080p Low, the system produces 217.9 FPS. When moving to 4K Low, the frame rate drops to 109.8 FPS, a reduction of approximately 49.6%. This halving of performance with a quadrupling of pixel count indicates a shift from a CPU-limited scenario at 1080p to a GPU-limited one at 4K.

The scaling becomes more dramatic at higher settings. At 1080p Ultra, the average is 148.6 FPS. At 4K Ultra, it is 60.3 FPS, a drop of 59.4%. This larger percentage decrease at Ultra settings confirms that the GPU’s shading units and memory bandwidth are saturated by the combination of high resolution and demanding effects. The RTX 5070’s 30.87 TFLOPS of FP32 performance is sufficient for 1440p gaming, but the data shows that 4K Ultra is a stretch goal rather than a native, high-refresh-rate target.

The fact that the 1080p Low score (217.9 FPS) is higher than the 4K Low score (109.8 FPS) by a factor of approximately two suggests that the CPU is capable of feeding the GPU far more frames than the GPU can render at higher resolutions. Conversely, the relatively small difference between 4K High (64.2 FPS) and 4K Ultra (60.3 FPS) indicates that the GPU is hitting a hard computational limit, where additional settings adjustments have diminishing returns. This analysis points to a system that is perfectly balanced for 1440p gaming, capable of delivering high frame rates at maximum settings, while 4K gaming will require a reduction in quality settings to maintain consistently high frame rates.
