Rust

Rust is a demanding survival title where frame pacing and consistency matter as much as raw averages, and the combination of the Intel Core Ultra 5 245 with the NVIDIA GeForce RTX 3080 Ti delivers a distinctive profile across resolutions and presets. The data shows this pairing sits at rank 633 out of 2,953 tested combos, placing it comfortably in the upper quartile of all systems evaluated for this game. With 14 cores and 14 threads running at a 3.50 GHz base clock and a 5.10 GHz boost clock, the Core Ultra 5 245 provides strong single-thread headroom, which Rust frequently leverages for physics, entity updates, and server-side simulation. The RTX 3080 Ti, with its 12 GB of GDDR6X memory and a 384-bit bus, supplies substantial bandwidth that becomes increasingly relevant as resolution climbs. This analysis breaks down the measured performance data, contextualizes the CPU and GPU roles, and offers actionable settings guidance based strictly on the provided benchmark results.

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

The Intel Core Ultra 5 245 is a 14-core, 14-thread processor built on the Arrow Lake-S architecture, fabricated on a 3 nm process by TSMC. Its base clock of 3.50 GHz and boost clock of 5.10 GHz are the key frequency figures in the data, and they directly influence how the CPU handles Rust’s single-threaded dependencies. The processor’s benchmark results reinforce this: a Cinebench R23 single-core score of 4,648 and a multi-core score of 32,924, alongside a PassMark single-thread score of 4,394. These numbers indicate that the CPU is well-balanced for a game like Rust, which often bottlenecks on core speed rather than core count, especially in populated servers where draw calls and logic updates accumulate.

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. For Rust, the L3 cache size is particularly relevant because the game’s world data, including terrain, building structures, and entity positions, gets frequently accessed and modified. A larger shared L3 can reduce memory latency and improve frame consistency, which the measured FPS numbers reflect. At 1080p Low settings, the combo achieves 224 FPS average, which is the highest measured value across all configurations, indicating that at lower resolutions and settings, the CPU is able to feed frames rapidly without being the primary constraint. However, the CPU’s 14 threads (with no hyperthreading) mean that heavily parallel workloads like shader compilation or background tasks could theoretically contend for resources, but the benchmark data shows no such degradation in Rust’s average FPS.

The processor’s memory bandwidth is rated at 102.4 GB/s over a dual-channel DDR5 interface, which is ample for the game’s data streaming needs. The integrated Arc Xe-LPG Graphics 64EU is present but irrelevant for this discrete GPU setup. The CPU’s percentile rank against all CPUs is 90, meaning it outperforms the vast majority of tested processors, and its nearest rivals include the AMD Ryzen 7 PRO 5755G (0.4% slower), AMD Ryzen 9 7900 (0.5% slower), Intel Xeon Gold 5318H (0.6% faster), and Intel Core i5-14600K (0.8% faster). These deltas are tiny, so the Core Ultra 5 245 sits in a very tight performance band around these alternatives, meaning that for Rust, the CPU choice among these options would likely produce nearly identical frame rates in CPU-bound scenarios.

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

The NVIDIA GeForce RTX 3080 Ti is built on the GA102 chip with the Ampere architecture, manufactured on an 8 nm process by Samsung. Its base clock is 1,365 MHz with a boost clock of 1,665 MHz, and the memory clock runs at 1,188 MHz with an effective data rate of 19 Gbps. The GPU’s 12 GB of GDDR6X memory is a critical specification for Rust, particularly at higher resolutions and settings where texture streaming and draw distances consume significant VRAM. The 384-bit memory bus delivers 912.4 GB/s of bandwidth, which helps maintain consistent frame rates even when the game loads large assets during world traversal.

The GPU’s compute resources include 10,240 shading units, 320 TMUs, and 112 ROPs, along with 80 RT cores and 320 tensor cores. For a game like Rust, which does not rely heavily on ray tracing in the standard benchmark settings, the rasterization performance is what drives the measured FPS. The pixel rate of 186.5 GPixel/s and texture rate of 532.8 GTexel/s indicate that the GPU can handle high-resolution rendering without becoming a bottleneck at lower settings. The PassMark G3D score of 26,896 and a percentile rank of 83 against all GPUs place it in a strong position, though its nearest rivals show a broader spread: the AMD Radeon Pro 5300 is 0.8% faster, the NVIDIA Tesla M40 24 GB is 1.2% slower, the NVIDIA Tesla M40 is 1.7% slower, and the NVIDIA GeForce RTX 5070 is 2% faster. These deltas are small, but the RTX 3080 Ti’s 12 GB VRAM capacity gives it an edge over older cards with less memory when running Rust at 4K Ultra, where the data shows an average of 39 FPS.

The GPU’s 350 W TDP and suggested 750 W PSU are hardware considerations, but for performance analysis, the key takeaway is that the RTX 3080 Ti scales well with resolution. At 1080p Low, the combo reaches 224 FPS, which suggests the GPU is not the limiting factor at that setting—the CPU likely is. At 4K Ultra, the average drops to 39 FPS, indicating that the GPU becomes heavily saturated. The 12 GB VRAM is sufficient for Rust’s texture requirements at all tested settings, as there is no indication of memory-related stuttering or frame drops in the min FPS values for Medium settings (e.g., 128 FPS at 1080p Medium).

How This Combo Ranks — use comboRankInGame vs other tested combos

The combo of the Intel Core Ultra 5 245 and the NVIDIA GeForce RTX 3080 Ti achieves a rank of 633 out of 2,953 tested combinations in Rust. This places it in the top 21.4% of all systems evaluated, which is a strong result but not top-tier. The rank reflects the overall performance across all measured resolutions and settings, weighted by the benchmark methodology. Compared to the CPU’s individual percentile of 90 and the GPU’s percentile of 83, the combo rank is somewhat lower, which suggests that the pairing is not perfectly balanced for Rust’s specific demands. Rust’s engine tends to favor high single-thread CPU performance, and while the Core Ultra 5 245 excels there, the RTX 3080 Ti’s raw power is partially underutilized at lower resolutions where the CPU caps frame rates.

The rank of 633 means there are 632 combos that outperform this pairing, many of which likely feature higher-end CPUs like the Ryzen 9 7900 or Core i5-14600K (which are close rivals) combined with faster GPUs. However, the delta between this combo and those just above it is likely small, given that the CPU rivals are within 1% of each other in average benchmark scores. The GPU rivals also cluster closely, so the combo rank is more about the overall balance than any single component deficiency. For a 1440p gaming target, this combo is well-suited, as the data shows strong FPS at that resolution across all settings, but at 4K Ultra, it falls below the 60 FPS threshold, which many higher-ranked combos likely exceed.

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

The measured FPS data provides a comprehensive view of how this combo performs across three resolutions and four settings presets. At 1920x1080, the results are as follows: Low settings yield an average of 224 FPS, Medium averages 150 FPS with a minimum of 128 FPS and a maximum of 173 FPS, High averages 127 FPS, and Ultra averages 96 FPS. The jump from Low to Medium is a 74 FPS drop, which is substantial and indicates that the Medium preset introduces significant GPU load. The step from Medium to High is a 23 FPS drop, and from High to Ultra is a 31 FPS drop, showing that each preset tier has a meaningful impact on frame rates at 1080p.

At 2560x1440, the averages are: Low at 154 FPS, Medium at 103 FPS (with min 88 and max 119), High at 87 FPS, and Ultra at 66 FPS. The drop from 1080p Low to 1440p Low is 70 FPS, which is a 31% reduction, while the drop from 1080p Ultra to 1440p Ultra is 30 FPS, a 31% reduction as well. This consistency suggests that the scaling is resolution-driven rather than settings-driven. At 4K (3840x2160), the averages are: Low at 91 FPS, Medium at 61 FPS (with min 52 and max 70), High at 52 FPS, and Ultra at 39 FPS. The 4K Low result of 91 FPS is notable because it is still above 60 FPS, indicating the GPU has enough headroom at lower settings even at this high resolution.

Comparing settings across resolutions, the Low preset at 4K (91 FPS) outperforms the Ultra preset at 1440p (66 FPS) by 25 FPS, which highlights that the GPU is capable of handling resolution increases better than settings increases. The Medium preset at each resolution shows the only min/max data available in the pack, with the 4K Medium min of 52 FPS being the lowest measured frame rate, suggesting that this setting combination can produce occasional drops below the average.

A: At 1920x1080, Low settings average 224 FPS, while Ultra settings average 96 FPS, a difference of 128 FPS. This represents a 57% reduction in average FPS when moving from the lowest to the highest preset.

Q: How does the combo’s rank in Rust compare to the individual component percentiles?

A: The combo ranks 633 out of 2,953 in Rust, which is in the top 21.4% of all tested combos. The CPU has a percentile rank of 90 against all CPUs, and the GPU has a percentile rank of 83 against all GPUs, so the combo’s rank is slightly lower than either component’s individual standing.

Q: Does the CPU or GPU become the bottleneck at 4K Low settings?

A: At 4K Low, the combo averages 91 FPS, which is significantly higher than 4K High (52 FPS) and 4K Ultra (39 FPS). This suggests the GPU is the primary bottleneck at higher settings, but at Low settings, the CPU’s 5.10 GHz boost clock is sufficient to keep frame rates high, meaning the GPU is still the limiting factor for pushing beyond 91 FPS.

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

Based on the measured FPS data, the optimal settings preset depends on the target resolution and desired frame rate. At 1920x1080, the High preset (127 FPS average) offers a strong balance between visual quality and performance, as it is nearly 2x the refresh rate of a standard 60 Hz monitor and provides better visuals than Low (224 FPS) or Medium (150 FPS) without the heavy cost of Ultra (96 FPS). For competitive play, Low settings at 1080p deliver the highest frame rate at 224 FPS, which is ideal for minimizing input latency, but the visual fidelity is significantly reduced.

At 2560x1440, the High preset (87 FPS) is the best choice for most users, as it maintains smooth gameplay above 60 FPS while offering good detail. The Ultra preset (66 FPS) is also playable, but the 21 FPS drop from High to Ultra may not justify the visual gains for some players. The Medium preset (103 FPS) is a good middle ground for those who prioritize frame rate over visuals, while Low (154 FPS) is for competitive scenarios.

At 3840x2160, the Medium preset (61 FPS) is the only setting that averages above 60 FPS aside from Low (91 FPS). Given that Low sacrifices significant visual quality, Medium is the recommended preset for 4K gaming, as it provides playable performance with acceptable fidelity. The High preset (52 FPS) and Ultra preset (39 FPS) are below the 60 FPS threshold and may result in inconsistent frame pacing, so they are not recommended for a smooth experience.

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

The FPS scaling from 1920x1080 to 3840x2160 reveals important insights about the balance between the CPU and GPU in this combo. At Low settings, the average FPS drops from 224 at 1080p to 154 at 1440p (a 70 FPS or 31% reduction) and then to 91 at 4K (a 63 FPS or 41% reduction from 1440p). This scaling pattern suggests that at Low settings, the CPU is capable of driving very high frame rates at 1080p, but the GPU becomes increasingly burdened as resolution rises, even with minimal graphical effects.

At Medium settings, the FPS drops from 150 at 1080p to 103 at 1440p (a 47 FPS or 31% reduction) and then to 61 at 4K (a 42 FPS or 41% reduction). The consistent percentage drops across settings indicate that the scaling is primarily resolution-driven, not settings-driven. At Ultra settings, the FPS drops from 96 at 1080p to 66 at 1440p (a 30 FPS or 31% reduction) and then to 39 at 4K (a 27 FPS or 41% reduction), showing the same relative scaling.

The fact that the percentage reduction from 1080p to 4K is roughly the same (around 57-59% across all settings) points to the GPU as the primary limiting component. If the CPU were the bottleneck, we would expect the FPS drop to be less severe at higher resolutions, as the GPU would have more time to render each frame. Instead, the data shows that the RTX 3080 Ti’s raw compute power is being fully utilized at 4K, while the CPU’s high single-thread performance is sufficient to avoid becoming a constraint even at 1080p Low where the GPU is idle much of the time. The 12 GB VRAM bandwidth of 912.4 GB/s is adequate for the resolution scaling, but the GPU’s shading units and ROPs are what limit performance at 4K Ultra, where the average falls to 39 FPS. This combination is best suited for 1440p gaming, where it delivers 66-154 FPS across all settings, while 4K is only viable at Low or Medium presets.
