Thief

The AMD Ryzen 7 7800X3D paired with the Intel Arc B570 delivers a playable but resolution-sensitive experience in Thief. The data shows a clear performance ceiling at 4K, while 1080p and 1440p offer smooth frame rates across most settings. This combination ranks in the 20th percentile of tested configurations (rank 2296 out of 2851), indicating that while it handles the game adequately at lower resolutions, it struggles to maintain high refresh rates at 4K Ultra.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 7800X3D is a desktop processor built on the Zen 4 architecture with a 5 nm process node from TSMC. It features 8 cores and 16 threads, with a base clock of 4.20 GHz and a boost clock of 5.00 GHz. The CPU's cache hierarchy is substantial: 64 KB of L1 per core, 1 MB of L2 per core, and a shared 96 MB of L3 cache. This large L3 pool is particularly relevant for Thief, a stealth game that often benefits from rapid data access for AI routines and level geometry.

Benchmark results place this CPU in the 83rd percentile among all processors, with an average benchmark score of 33079. In multi-threaded workloads, the 3DMark 16-thread score of 7980 and the max-thread score of 7967 show near-identical scaling, meaning the processor's 8 cores/16 threads are efficiently utilized without significant overhead. The single-thread performance is also strong, with a 3DMark single-thread score of 959 and a Geekbench single-core score of 2426, which matters for Thief's game logic and physics calculations that often rely on fewer threads.

Compared to its nearest rivals, the 7800X3D essentially ties with the AMD Ryzen 7 8700G (0% delta) and Intel Core i7-13650HX (0% delta), while slightly trailing the AMD Ryzen 7 7745HX (0% delta) and AMD Ryzen 9 PRO 6950H (-0.4%). The Cinebench R23 multicore score of 16817 and single-core score of 1713 further confirm that this CPU provides balanced performance. For Thief, the CPU appears more than capable of feeding the GPU, as evidenced by the 133 FPS average at 1080p Low settings, which is a CPU-bound scenario where the 7800X3D's strengths are fully exposed.

The processor's memory support includes DDR5 with dual-channel configuration and 83.2 GB/s bandwidth, which pairs well with the game's need for rapid asset streaming. With a TDP of 120 W and support for PCIe Gen 5 (24 lanes), the CPU is not a bottleneck in this pairing. The data indicates that at lower resolutions, the frame rates scale linearly with CPU performance, suggesting the 7800X3D is doing its job without holding back the Arc B570.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B570 is a Battlemage-generation GPU based on the Xe2-HPG architecture, built on a 5 nm process at TSMC. It carries 10 GB of GDDR6 memory on a 160-bit bus, delivering 380.0 GB/s of bandwidth. The GPU operates at a fixed 2500 MHz base and boost clock, with memory running at 2375 MHz (19 Gbps effective). With 2304 shading units, 144 TMUs, and 80 ROPs, the Arc B570 provides a raw compute throughput of 11.52 TFLOPS FP32 and a texture rate of 360.0 GTexel/s.

This GPU sits in the 65th percentile among all GPUs, with an average benchmark score of 20556. Its nearest rivals include the NVIDIA GeForce RTX 3070 Mobile (0.1% delta), Intel Arc A750 (-0.1% delta), and AMD Radeon R9 M390X (-0.5% delta). The 10 GB VRAM is sufficient for Thief, a 2014 title that does not demand excessive memory, allowing the GPU to focus on rendering rather than swapping assets.

The GPU's performance in Thief shows a clear dependency on resolution. At 1080p, the Arc B570 delivers 133 FPS on Low settings, but this drops to 73 FPS on Ultra — a 45% reduction. The 1440p results follow a similar pattern, with 91 FPS on Low and 50 FPS on Ultra. At 4K, the GPU becomes the limiting factor: 54 FPS on Low, 41 FPS on Medium, 31 FPS on High, and only 29 FPS on Ultra. These numbers indicate that the Arc B570's 80 ROPs and 200.0 GPixel/s pixel rate are insufficient for 4K Ultra, but the card handles 1080p and 1440p competently.

The GPU's memory bandwidth of 380.0 GB/s is adequate for Thief's textures, but the 160-bit bus width limits high-resolution performance. The DirectX 12 Ultimate support (12_2) ensures compatibility with modern rendering paths, and the Vulkan 1.4 API support provides efficient draw call handling. The data shows the GPU's passmark G3D score of 14195 and Geekbench Vulkan score of 96844 are reasonable for this tier, but the 4K Ultra result of 29 FPS falls below the 30 FPS playability threshold, confirming the GPU is the primary constraint at that resolution.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a steep performance decline as resolution increases. Starting at 1080p High (77 FPS), the frame rate drops to 53 FPS at 1440p High (-31%) and further to 31 FPS at 4K High (-60%). The same pattern holds across all settings. At Low, 1080p delivers 133 FPS, 1440p delivers 91 FPS (-32%), and 4K delivers 54 FPS (-59%). Medium settings show 101 FPS at 1080p, 69 FPS at 1440p (-32%), and 41 FPS at 4K (-59%). Ultra settings follow with 73 FPS at 1080p, 50 FPS at 1440p (-32%), and 29 FPS at 4K (-60%).

This consistent ~32% drop from 1080p to 1440p and ~60% drop from 1080p to 4K across all settings indicates a GPU-bound scenario. The CPU's performance does not vary with resolution — it delivers the same instructions per frame regardless of pixel count. Since the 7800X3D's scores are identical at all resolutions (the CPU benchmarks are resolution-independent), the FPS scaling is solely attributable to the Arc B570's rendering capacity. The pixel rate of 200.0 GPixel/s and the 160-bit memory bus create a bottleneck that becomes more pronounced at 4K, where the GPU must process four times the pixels of 1080p.

The fact that the FPS drop is nearly identical in percentage terms across Low, Medium, High, and Ultra settings reinforces that this is a pure resolution limit, not a settings-dependent effect. At 1080p, the GPU has enough headroom to render the scene quickly, but at 4K, the fill rate and memory bandwidth constraints cap performance at roughly half the 1080p frame rate. The 4K Ultra result of 29 FPS is particularly telling — it indicates that the GPU's 80 ROPs cannot sustain the pixel throughput required for 4K with maxed-out effects, regardless of CPU capability.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the system delivers its best performance. Low settings produce an average of 133 FPS, Medium settings yield 101 FPS with a minimum of 86 and maximum of 116, High settings reach 77 FPS, and Ultra settings fall to 73 FPS. The 60 FPS threshold is exceeded comfortably at all settings, making 1080p viable for high-refresh-rate monitors.

At 2560x1440, performance remains playable but requires settings adjustments. Low settings average 91 FPS, Medium settings average 69 FPS with a minimum of 59 and maximum of 79, High settings drop to 53 FPS, and Ultra settings reach 50 FPS. The Medium preset maintains a minimum above 55 FPS, which is crucial for consistent gameplay, while High and Ultra dip below 60 FPS averages.

At 3840x2160, the system struggles to maintain playable frame rates. Low settings average 54 FPS, Medium settings average 41 FPS with a minimum of 35 and maximum of 47, High settings average 31 FPS, and Ultra settings average 29 FPS. Only the Low preset keeps the average above 30 FPS, and even that has no guaranteed minimum, making 4K a challenge for this combination.

The Medium settings rows provide the only min/max data, revealing stability metrics. At 1080p Medium, the range is 86-116 FPS, a 30 FPS spread that indicates smooth frame pacing. At 1440p Medium, the range narrows to 59-79 FPS, still acceptable. At 4K Medium, the range is 35-47 FPS, which shows tighter variance but at a low average. The absence of min/max data for other settings suggests those runs were less consistent.

Settings Recommendations — which preset gives the best experience per the measured rows

The optimal settings depend on the target resolution. For 1080p, the Ultra preset at 73 FPS is recommended, as it provides the highest visual fidelity while maintaining a frame rate well above 60 FPS. The gap between High (77 FPS) and Ultra (73 FPS) is only 4 FPS, making Ultra the clear choice for maximum quality without sacrificing smoothness.

For 1440p, the Medium preset at 69 FPS is the best option. It delivers a 38% improvement over Ultra (50 FPS) while only sacrificing some visual effects. The minimum of 59 FPS ensures no drops below the 60 FPS threshold, which is critical for a stealth game where frame hitches can disrupt timing. High settings at 53 FPS are borderline, and Ultra at 50 FPS is too low for comfortable play.

For 4K, the Low preset at 54 FPS is the only viable choice. It provides a playable experience, though the lack of min/max data means stability is uncertain. Medium at 41 FPS is below the 45 FPS comfort zone, and High/Ultra (31/29 FPS) are unplayable. Users prioritizing 4K should accept Low settings or consider lowering the resolution to 1440p for a better experience.

The data indicates that the Medium preset offers the best balance across all resolutions. At 1080p, it delivers 101 FPS (versus 133 Low and 73 Ultra), at 1440p it delivers 69 FPS (versus 91 Low and 50 Ultra), and at 4K it delivers 41 FPS (versus 54 Low and 29 Ultra). For users who want consistent performance without maxing out the GPU, Medium is the recommended preset. However, at 1440p and 1080p, the step up to Ultra is feasible given the 73 FPS and 50 FPS results respectively, making Ultra the choice for those with high-refresh-rate displays who prioritize visuals over absolute frame rate.
