Rust

The Intel Core Ultra 5 245 paired with the NVIDIA GeForce RTX 3080 delivers a highly capable Rust experience, but the data reveals a clear hierarchy between resolution and settings. At 1080p, the combo is exceptionally fast, with average framerates ranging from 93 FPS on Ultra to 216 FPS on Low. Moving to 1440p, performance remains strong, with the High preset hitting 84 FPS and Low reaching 148 FPS. At 4K, the system begins to show its limits, with the Ultra preset dropping to 38 FPS and High settling at 50 FPS. The scaling pattern across resolutions indicates that the RTX 3080 becomes the primary limiting factor as pixel count increases, while the Core Ultra 5 245 has ample headroom at lower resolutions.

Resolution Scaling

The measured FPS data shows a predictable decline as resolution increases, but the magnitude of that decline varies significantly by settings preset. At the Low preset, the transition from 1080p to 1440p results in a drop from 216 FPS to 148 FPS, a reduction of 68 FPS or roughly 31%. Moving from 1440p to 4K at Low, the average falls from 148 FPS to 88 FPS, another 60 FPS loss. This suggests that at Low settings, the CPU is still capable of pushing high framerates even at 4K, but the GPU workload is escalating.

The Medium preset shows a similar trend, with averages of 145 FPS at 1080p, 100 FPS at 1440p, and 59 FPS at 4K. The drop from 1440p to 4K here is 41 FPS, which is a 41% reduction, indicating a heavier reliance on GPU throughput. High settings exhibit the steepest relative decline: 122 FPS at 1080p, 84 FPS at 1440p, and 50 FPS at 4K. The 4K result is only 41% of the 1080p figure, confirming that the RTX 3080’s 10 GB of VRAM and 760.3 GB/s bandwidth are being taxed heavily at higher pixel densities.

Ultra settings provide the clearest evidence of GPU-bound behavior. At 1080p, the combo manages 93 FPS, which drops to 64 FPS at 1440p and 38 FPS at 4K. The 4K Ultra result is the lowest measured in the entire dataset, and the gap between 1080p and 4K Ultra is 55 FPS, or a 59% performance loss. This pattern strongly suggests that the RTX 3080, with its 320 W TDP and 8 nm process node, is the limiting component at 4K, whereas the Core Ultra 5 245’s 14 cores and 5.10 GHz boost clock are sufficient to keep pace at 1080p and 1440p.

How This Combo Ranks

In the broader context of tested combinations, this specific pairing of the Intel Core Ultra 5 245 and NVIDIA GeForce RTX 3080 ranks 731st out of 2,953 combos for Rust. This places it in the top 24.8% of all tested systems, which is a respectable position given the mid-range-to-high-end nature of both components. The rank suggests that while the combo is not at the very top tier, it outperforms the majority of configurations in the database, particularly those with older CPUs or lower-tier GPUs.

The CPU itself holds a percentile of 90 among all tested processors, meaning it outperforms 90% of CPUs in general benchmark suites. Its average benchmark score of 48,995 is nearly identical to that of the AMD Ryzen 7 PRO 5755G (49,196, a delta of -0.4%) and the AMD Ryzen 9 7900 (49,228, a delta of -0.5%). It also edges out the Intel Xeon Gold 5318H (48,698, +0.6%) and the Intel Core i5-14600K (48,618, +0.8%). These tiny deltas indicate that the Core Ultra 5 245 is performance-competitive with several strong alternatives, and its 90th percentile standing suggests it is rarely a bottleneck in gaming scenarios.

The GPU, however, sits at the 68th percentile among all graphics cards, with an average benchmark score of 23,172. Its nearest rivals in the database include the NVIDIA P106-100 (23,249, -0.3%), AMD Radeon Pro Vega 16 (23,250, -0.3%), AMD Radeon RX 6600M (23,273, -0.4%), and AMD Radeon R9 M290X (23,276, -0.4%). These comparisons show that the RTX 3080 is clustered with cards that are generally considered lower-tier, which is surprising given its 8704 shading units and 29.77 TFLOPS FP32 performance. The discrepancy likely reflects the database’s specific benchmark weighting, but for Rust, the measured FPS data is more relevant than synthetic scores.

GPU Role

The NVIDIA GeForce RTX 3080 is built on the Ampere architecture with a GA102 chip, manufactured on Samsung’s 8 nm process. It features 10 GB of GDDR6X memory on a 320-bit bus, delivering 760.3 GB/s of bandwidth. The memory clocks run at 1188 MHz, with an effective data rate of 19 Gbps, which is critical for texture-heavy scenes in Rust. The GPU’s base clock is 1440 MHz, boosting to 1710 MHz, and it contains 68 RT cores and 272 tensor cores, though Rust does not heavily utilize ray tracing.

The 10 GB VRAM capacity is a notable factor in the 4K results. At 3840x2160 with Ultra settings, the average FPS drops to 38, and even at High it only reaches 50 FPS. This suggests that the frame buffer is being saturated, causing the GPU to rely on slower memory paging or reduced texture quality. In contrast, at 1080p, the 10 GB is ample, and the GPU’s 465.1 GTexel/s texture rate and 164.2 GPixel/s pixel rate allow for 216 FPS on Low and 93 FPS on Ultra. The FP32 throughput of 29.77 TFLOPS is also sufficient for the game’s physics and rendering calculations at lower resolutions.

The GPU’s 68th percentile ranking among all cards is modest, but the measured Rust performance shows it can still deliver high framerates at 1080p and 1440p. The 4K results are the weak point, where the 320 W TDP and dual-slot cooling design are working hard to maintain stability. The 1x 12-pin power connector and 700 W suggested PSU indicate that this is a power-hungry card, but for a game like Rust, the primary concern is the VRAM and memory bandwidth at higher resolutions.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and desired framerate. For 1080p gaming, the High preset at 122 FPS is the best balance of visual quality and performance, as it provides a smooth experience on standard 60 Hz or 144 Hz monitors. The Ultra preset at 93 FPS is also viable, but the 29 FPS difference between High and Ultra may not justify the visual gains for most players. The Low preset at 216 FPS is excessive unless the user has a 240 Hz display, and the Medium preset at 145 FPS offers a middle ground.

At 1440p, the High preset at 84 FPS is the recommended choice, as it maintains a framerate above 60 FPS while preserving visual fidelity. The Medium preset at 100 FPS is also strong, but it sacrifices some graphical detail. The Ultra preset at 64 FPS is borderline, and the Low preset at 148 FPS is overkill for most monitors. For 4K, the data suggests that only the Low preset (88 FPS) provides a consistently smooth experience, while the Medium preset (59 FPS) hovers near the 60 FPS threshold. The High preset at 50 FPS and Ultra at 38 FPS are not recommended for competitive play, as they introduce noticeable stutter.

In summary, the High preset at 1080p or 1440p offers the best experience per the measured rows, balancing framerate and visual quality. For 4K, users should stick to Low or Medium settings to avoid the severe performance drops seen at High and Ultra.

CPU Role

The Intel Core Ultra 5 245 is a 14-core, 14-thread processor based on the Arrow Lake architecture, manufactured on TSMC’s 3 nm process. It has a base clock of 3.50 GHz and a boost clock of 5.10 GHz, with 24 MB of shared L3 cache and 3 MB of L2 cache per core. The CPU supports DDR5 memory with a dual-channel bus and a bandwidth of 102.4 GB/s, which is sufficient for feeding the RTX 3080 in Rust. Its 65 W TDP is modest, and the integrated Arc Xe-LPG Graphics 64EU is present but irrelevant for gaming with a discrete GPU.

The CPU’s benchmark scores show strong single-thread and multi-thread performance. In Cinebench R23, it scores 4,648 single-core and 32,924 multi-core, while in PassMark it achieves 4,394 single-thread and 38,706 multithread. These numbers indicate that the Core Ultra 5 245 can handle Rust’s physics and simulation logic without bottlenecking the GPU, especially at 1080p and 1440p. The 90th percentile ranking among all CPUs confirms that it is a high-end processor, and its nearest rivals in the database are all within 1% of its average score.

In Rust, the CPU’s role is most evident at 1080p Low, where the 216 FPS result suggests that the processor can push framerates far beyond what the GPU can render at higher settings. At 4K, the CPU is not the limiting factor; the GPU’s VRAM and bandwidth are the constraints. The 14 cores and 14 threads (without hyperthreading) are more than adequate for a game that is typically single-thread-bound, and the 5.10 GHz boost clock ensures fast response times in combat scenarios.

Measured FPS Breakdown

The measured FPS data covers three resolutions and four settings presets, providing a comprehensive picture of performance. At 1920x1080, the Low preset delivers an average of 216 FPS, the Medium preset averages 145 FPS with a range of 123-166 FPS, the High preset averages 122 FPS, and the Ultra preset averages 93 FPS. The spread from Low to Ultra is 123 FPS, indicating that the GPU has significant headroom at this resolution, and the CPU is not a bottleneck.

At 2560x1440, the Low preset averages 148 FPS, the Medium preset averages 100 FPS with a range of 85-115 FPS, the High preset averages 84 FPS, and the Ultra preset averages 64 FPS. The performance drops are more pronounced here, with the Ultra preset falling below 70 FPS, which is still playable but not ideal for fast-paced action. The Medium preset offers the best balance, with a 100 FPS average and a narrow 30 FPS variance.

At 3840x2160, the Low preset averages 88 FPS, the Medium preset averages 59 FPS with a range of 50-68 FPS, the High preset averages 50 FPS, and the Ultra preset averages 38 FPS. The 4K results show a clear GPU limitation, as even the Low preset cannot reach 90 FPS, and the Ultra preset drops below 40 FPS. The Medium preset’s minimum of 50 FPS indicates occasional dips below the 60 FPS threshold, making it a marginal choice for 4K gaming.

The data shows that the combo is best suited for 1080p and 1440p gaming, where it can deliver high framerates across all presets. At 4K, users must compromise on settings to maintain playable performance, and the RTX 3080’s 10 GB VRAM becomes a limiting factor at Ultra settings. Overall, the Intel Core Ultra 5 245 and NVIDIA GeForce RTX 3080 is a well-matched pairing for Rust, with the CPU providing ample headroom and the GPU handling the graphics load effectively up to 1440p.
