Thief

The AMD Ryzen 7 5800X and AMD Radeon RX 9070 combination delivers a robust experience in Thief, with the data showing that the GPU is the primary driver of performance scaling across resolutions and settings. The measured frame rates reveal a system that is well-balanced at 1080p, but which becomes increasingly GPU-bound as the resolution climbs, with the CPU maintaining a strong supporting role throughout.

Resolution Scaling

The measured FPS data demonstrates a clear and predictable pattern of performance degradation as resolution increases from 1920x1080 to 3840x2160. At Ultra settings, the average frame rate drops from 130.6 FPS at 1080p to 93.3 FPS at 1440p, and finally to 52.2 FPS at 4K. This represents a substantial 60% reduction in frame rate from 1080p to 4K, indicating that the rendering load at higher resolutions is significantly taxing the GPU's capabilities.

The scaling behavior varies by settings preset. At Low settings, the frame rate decreases from 171.4 FPS at 1080p to 151.7 FPS at 1440p (an 11.5% drop), and then to 98.1 FPS at 4K (a 35.4% drop from 1440p). This pattern suggests that at lower settings, the system retains more headroom, allowing the GPU to handle the resolution increase more gracefully. Conversely, at Ultra settings, the drop from 1440p to 4K is 44.1%, highlighting that the most demanding preset pushes the GPU to its limits.

The data indicates that the limiting component shifts with resolution. At 1080p, the relatively small performance difference between Low (171.4 FPS) and Ultra (130.6 FPS) – a 23.8% gap – suggests that the CPU is capable of feeding the GPU adequately, but the GPU is already becoming a bottleneck even at this resolution. At 4K, the gap between Low (98.1 FPS) and Ultra (52.2 FPS) widens to 46.8%, confirming that the GPU is the dominant constraint at higher resolutions.

GPU Role

The AMD Radeon RX 9070, based on the Navi 48 chip and RDNA 4.0 architecture, is the primary performance driver in Thief. The GPU's 16 GB of GDDR6 memory on a 256-bit bus provides 644.6 GB/s of bandwidth, which is ample for the game's textures and geometry at all tested resolutions. The memory clock runs at 2518 MHz (20.1 Gbps effective), while the GPU's base clock is 1330 MHz, with a boost clock of 2520 MHz and a game clock of 2070 MHz.

The GPU's compute resources include 3584 shading units, 224 TMUs, and 128 ROPs, delivering a pixel rate of 322.6 GPixel/s and a texture rate of 564.5 GTexel/s. The FP32 throughput of 36.13 TFLOPS provides substantial raw compute power for the game's lighting and shadow calculations. These specifications align with the observed frame rates: the GPU's performance in the PassMark G3D benchmark (25381) and its 3DMark Steel Nomad DX12 score (6290) corroborate its ability to handle DirectX 12 workloads like Thief.

Interestingly, the GPU's nearest rivals in the benchmark database include the NVIDIA A2 (avgScore 34866, deltaPct -0.2) and the NVIDIA Quadro GV100 (avgScore 34677, deltaPct 0.3), indicating that the RX 9070 sits in a competitive performance tier. The GPU's percentile ranking of 79 among all GPUs confirms its position as a high-end part. The 16 GB VRAM capacity ensures that even at 4K Ultra settings, memory capacity is not a limiting factor, allowing the GPU to focus on compute and rendering rather than memory swapping.

FAQ

*Q: What is the average frame rate at 1440p with High settings in Thief?*

A: The measured average FPS at 2560x1440 with High settings is 96.0 FPS, which indicates a smooth experience for most display configurations.

Q: How does the RX 9070 perform at 4K Ultra settings?

A: At 3840x2160 with Ultra settings, the average frame rate is 52.2 FPS. This is below the 60 FPS threshold, suggesting that users may need to adjust settings for a perfectly smooth 4K experience.

Q: Is the CPU or GPU the bottleneck at 1080p?

A: The data suggests the GPU is the primary bottleneck even at 1080p. At 1920x1080, the frame rate ranges from 171.4 FPS at Low to 130.6 FPS at Ultra, a 23.8% spread, indicating that the GPU's performance limits the frame rate more than the CPU's capabilities.

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

A: At 2560x1440, Low settings yield 151.7 FPS, while Ultra settings yield 93.3 FPS. This represents a 38.5% reduction in frame rate when moving from Low to Ultra, highlighting the significant impact of the preset on GPU load.

*Q: Does the 16 GB VRAM of the RX 9070 cause any issues in Thief?*

A: No. The 16 GB GDDR6 memory with 644.6 GB/s bandwidth provides more than sufficient capacity and bandwidth for the game's requirements at all tested resolutions and settings, as evidenced by the consistent frame rates without any indication of memory-related stuttering.

Q: How does the RX 9070's performance compare to its nearest rivals in synthetic benchmarks?

A: The RX 9070 has an average benchmark score of 34780, which is 0.2% higher than the NVIDIA A2 (34866) and 0.3% lower than the NVIDIA Quadro GV100 (34677). This places it in a tightly contested performance bracket.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across all resolution and settings combinations. At 1920x1080, the RX 9070 delivers 171.4 FPS at Low settings, 154.3 FPS at Medium, 141.7 FPS at High, and 130.6 FPS at Ultra. These results indicate that at 1080p, the system is capable of exceeding 130 FPS even at the highest settings, making it well-suited for high-refresh-rate monitors.

Moving to 2560x1440, the frame rates remain strong: 151.7 FPS at Low, 126.5 FPS at Medium, 96.0 FPS at High, and 93.3 FPS at Ultra. The transition from 1080p to 1440p results in frame rate reductions of 11.5% at Low, 18.0% at Medium, 32.2% at High, and 28.6% at Ultra. This shows that the GPU handles the resolution increase admirably, with the most significant relative drop occurring at High settings.

At 3840x2160, the performance becomes more demanding: 98.1 FPS at Low, 76.7 FPS at Medium, 54.6 FPS at High, and 52.2 FPS at Ultra. The reduction from 1440p to 4K is substantial across all settings, with the largest percentage drop of 44.1% occurring at Ultra settings. The data shows that 4K gaming is feasible with this combination, but users targeting 60 FPS will need to use Medium settings or lower, as High and Ultra presets fall below this threshold.

CPU Role

The AMD Ryzen 7 5800X serves as a strong foundation for the RX 9070 in Thief. This 8-core, 16-thread processor based on the Zen 3 architecture (Vermeer) features a base clock of 3.80 GHz and a boost clock of 4.70 GHz. The CPU's 32 MB of L3 cache and 512 KB of L2 cache per core provide ample fast storage for game data, while its dual-channel DDR4 memory support with 51.2 GB/s bandwidth ensures the GPU receives data without stalling.

The CPU's benchmark results demonstrate its capability to keep up with the GPU's demands. In Cinebench R23, the 5800X scores 23571 in multicore and 3327 in single-core tests. The 3DMark single-thread score of 943 and multi-thread score of 7578 further confirm its strength in both lightly-threaded and heavily-threaded workloads. The PassMark multithread score of 27732 and single-thread score of 3445 indicate balanced performance that is well-suited for gaming.

The CPU's percentile ranking of 84 among all CPUs places it in the upper echelon of processors, and its average benchmark score of 27606 is nearly identical to its nearest rivals, including the AMD Ryzen 7 5800 (avgScore 27535, deltaPct 0.3) and the AMD Ryzen 5 8500GE (avgScore 27708, deltaPct -0.4). This performance level is more than sufficient to avoid bottlenecking the GPU in Thief, as evidenced by the frame rate scaling patterns. At 1080p, where CPU load is relatively higher, the 5800X's strong single-thread performance (3327 in Cinebench R23 single-core) ensures that the GPU receives a consistent stream of draw calls, allowing the RX 9070 to achieve its maximum frame rates. The data confirms that the CPU is not the limiting component in this configuration, even at lower resolutions where the CPU's role is more prominent.
