Rust

The pairing of the Intel Core Ultra 5 245 with the AMD Radeon RX 7600 XT produces a spread of framerates across Rust’s presets that clearly delineates the workload’s shifting bottlenecks. At 1080p, the system is capable of triple-digit averages on lower settings, but the 4K Ultra result collapses to 25 FPS, indicating a hard ceiling imposed by the graphics card. This analysis breaks down the measured data, contextualizes the hardware’s standing among tested combos, and provides a roadmap for optimizing the experience.

Resolution Scaling

The measured FPS data reveals a steep performance degradation as resolution increases, a pattern typical of a system where the GPU becomes the primary constraint at higher pixel counts. At 1080p Low, the combination produces an average of 145 FPS. Moving to 1440p Low drops that figure to 99 FPS, a reduction of approximately 32%. At 4K Low, the average falls to 59 FPS, which is a further 40% decline from the 1440p result. This progression shows that even on the least demanding preset, the rendering load scales aggressively with pixel count.

The scaling behavior is even more pronounced on higher settings. At High settings, the transition from 1080p (82 FPS) to 1440p (56 FPS) represents a 32% drop, but the move from 1440p to 4K (33 FPS) is a 41% reduction. For Medium settings, the numbers are 97 FPS at 1080p, 67 FPS at 1440p, and 39 FPS at 4K, with the latter transition again showing the largest relative loss. This non-linear decline suggests that memory bandwidth and raw pixel throughput are being saturated at 4K, as the RX 7600 XT’s 128-bit bus and 288.0 GB/s bandwidth struggle to feed the shader array.

The data indicates that the limiting component shifts with resolution. At 1080p, the CPU’s 14 cores and 5.10 GHz boost clock are likely capable of keeping up with the GPU’s output, allowing the system to reach 145 FPS on Low. However, the 4K Ultra result of 25 FPS is a stark indicator that the GPU is the constraining factor at that resolution, as the RX 7600 XT’s 22.57 TFLOPS of FP32 compute is insufficient for the pixel workload. The difference between the 4K Low (59 FPS) and 4K High (33 FPS) results—a 44% performance gap—further confirms that the graphics card’s shading units and memory interface are the bottleneck, not the processor.

GPU Role

The AMD Radeon RX 7600 XT is built on the RDNA 3.0 architecture with the Navi 33 chip, fabricated on a 6 nm process. Its specifications include 16 GB of GDDR6 memory on a 128-bit bus, yielding a bandwidth of 288.0 GB/s. The GPU operates at a base clock of 1980 MHz and a boost clock of 2755 MHz, with a game clock rated at 2470 MHz. These clocks, combined with 2048 shading units and 64 ROPs, produce a pixel rate of 176.3 GPixel/s and a texture rate of 352.6 GTexel/s.

In Rust, the GPU’s role is most visible in the resolution scaling data. The 16 GB frame buffer is not a limiting factor at any of the tested settings, as even 4K Ultra fits within that capacity. Instead, the bottleneck is the memory bandwidth and the compute throughput. The step from Medium to High at 4K costs 6 FPS (from 39 to 33), while the step from High to Ultra costs another 8 FPS (from 33 to 25). This suggests that the shader complexity and memory traffic of the Ultra preset overwhelm the GPU’s capabilities. The 128-bit memory interface is likely the culprit, as higher resolutions demand more bandwidth for texture fetches and framebuffer operations, and the 288.0 GB/s figure is modest by modern standards.

The GPU’s benchmark scores place it in the 60th percentile among all GPUs, with an average score of 17083. Its nearest rivals include the NVIDIA GeForce RTX 3070, which scores 17208 (a -0.7% delta), and the NVIDIA GeForce GTX 690, which scores 17037 (a +0.3% delta). This indicates the RX 7600 XT sits in a performance tier where it can handle 1080p gaming comfortably but is not designed for high-refresh 4K gaming. The measured FPS data aligns with this positioning: 1080p results are playable across all settings, while 4K results are only viable on Low settings, where the 59 FPS average is acceptable.

How This Combo Ranks

The combination of the Intel Core Ultra 5 245 and the AMD Radeon RX 7600 XT ranks 2380 out of 3723 tested combinations for Rust. This places it in the lower-middle portion of the database, indicating that while it can run the game, many other hardware pairings deliver higher average framerates. The combo’s percentile ranking is not directly provided, but the rank of 2380 out of 3723 suggests it outperforms roughly 36% of tested systems. This is a modest result, likely dragged down by the GPU’s limitations at higher resolutions.

Breaking down the components, the CPU ranks in the 90th percentile among all processors with an average benchmark score of 48995. Its nearest rivals include the AMD Ryzen 9 7900 (avg score 49228, a -0.5% delta) and the Intel Core i5-14600K (avg score 48618, a +0.8% delta). This shows the Core Ultra 5 245 is a strong processor that should not bottleneck the GPU in most scenarios. Conversely, the GPU sits in the 60th percentile, which is significantly lower. The combination’s rank in Rust is therefore likely influenced more by the GPU than the CPU, as the processor has the headroom to push higher framerates if the graphics card could keep up.

The data confirms this interpretation. At 1080p Low, the combo achieves 145 FPS, which is a solid result. However, at 4K Ultra, the 25 FPS average is below the threshold for smooth gameplay. If the CPU were the limiting factor, we would expect to see framerates plateau across resolutions, but the continuous decline from 1080p to 4K indicates the GPU is the primary constraint. The combo’s rank of 2380 suggests that users seeking higher performance in Rust would benefit more from a more powerful GPU than a faster processor.

Measured FPS Breakdown

The measured FPS data provides a complete matrix of performance across three resolutions and four settings presets. At 1920x1080, the system delivers an average of 145 FPS on Low, 97 FPS on Medium, 82 FPS on High, and 62 FPS on Ultra. The Medium preset records a minimum of 82 FPS and a maximum of 112 FPS, indicating some frame-time variance, but the overall averages are smooth. The 1080p results show a clear scaling pattern: each step up in settings reduces performance by roughly 15-20 FPS, which is a manageable trade-off for visual fidelity.

At 2560x1440, the averages are 99 FPS on Low, 67 FPS on Medium, 56 FPS on High, and 43 FPS on Ultra. The Medium preset again shows a range of 57 to 77 FPS. The transition from 1080p to 1440p costs approximately 30% performance across all settings, which is consistent with the increased pixel count. The 1440p Ultra result of 43 FPS is borderline playable for a survival game, but it is approaching the lower limit for a smooth experience.

At 3840x2160, the averages drop to 59 FPS on Low, 39 FPS on Medium, 33 FPS on High, and 25 FPS on Ultra. The Medium preset shows a minimum of 34 FPS and a maximum of 45 FPS. These results are generally below the 60 FPS target for competitive play, with only the Low preset achieving a playable average. The 4K Ultra result of 25 FPS is not suitable for gameplay, as it would result in noticeable stuttering and input lag. The data suggests that 4K is only viable on the Low preset for this hardware combination.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend heavily on the target resolution and the user’s preference for smoothness versus visual quality. At 1920x1080, the High preset delivers 82 FPS, which is a good balance between performance and image quality. The Ultra preset at 62 FPS is still playable, but the 20 FPS drop from High may not justify the marginal visual improvements. For users seeking maximum smoothness, the Low preset at 145 FPS provides an exceptionally high refresh rate experience, though it sacrifices shadows and texture detail.

At 2560x1440, the Medium preset offers 67 FPS, which is the most balanced option. The High preset at 56 FPS is acceptable for a slower-paced survival game, but it may feel less responsive in combat situations. The Ultra preset at 43 FPS is playable but not ideal, as it falls below the 60 FPS threshold. The Low preset at 99 FPS is the best choice for competitive play, offering a smooth experience without the visual overhead.

At 3840x2160, the only viable option is the Low preset, which delivers 59 FPS. The Medium preset at 39 FPS is below the playable threshold, and the High and Ultra presets are not recommended due to their low averages. For users with 4K displays, the data indicates that this hardware combination is not suited for high settings, and the Low preset is the only way to achieve a consistent framerate. The 16 GB of VRAM does not help at this resolution because the bottleneck is the GPU’s compute and bandwidth, not memory capacity.

CPU Role

The Intel Core Ultra 5 245 is a 14-core, 14-thread processor based on the Arrow Lake architecture, manufactured on a 3 nm process by TSMC. It has a base clock of 3.50 GHz and a boost clock of 5.10 GHz, with a TDP of 65 W. The CPU’s cache hierarchy includes 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. It supports DDR5 memory with a dual-channel interface, providing a bandwidth of 102.4 GB/s.

In Rust, the CPU’s role is less pronounced than the GPU’s, as evidenced by the resolution scaling data. At 1080p Low, the system achieves 145 FPS, which is a high enough framerate that the CPU’s single-thread performance is likely a contributing factor. The CPU’s Cinebench R23 single-core score of 4648 and multi-core score of 32924 indicate strong performance that should not bottleneck the GPU in most scenarios. The PassMark single-thread score of 4394 further confirms this, placing it in the 90th percentile among all CPUs.

However, the CPU’s 14 cores and 14 threads (no hyperthreading) may limit performance in heavily threaded scenarios. Rust is known to be a CPU-intensive game, particularly in large multiplayer servers with many entities. The CPU’s multi-threaded benchmark scores, such as the PassMark multi-thread score of 38706, suggest it can handle these workloads, but the lack of extra threads compared to rivals like the AMD Ryzen 9 7900 (which scores 49228 in average benchmark) could be a minor disadvantage. The deltaPct of -0.5% against the Ryzen 9 7900 indicates the Core Ultra 5 245 is slightly slower in overall synthetic benchmarks, but this difference is unlikely to be noticeable in real-world gaming.

The CPU’s memory bandwidth of 102.4 GB/s is sufficient for the GPU’s needs, as the RX 7600 XT’s 288.0 GB/s bandwidth is the limiting factor at higher resolutions. At 1080p, where the GPU is less stressed, the CPU’s ability to feed frames quickly becomes more important, and the measured 145 FPS on Low shows it can do so effectively. The data suggests that the Core Ultra 5 245 is a capable partner for the RX 7600 XT in this game, but it is not the component holding back performance.
