Rust

Rust is a demanding survival title that stresses both CPU and GPU heavily, and the pairing of the Intel Core Ultra 5 245 with the NVIDIA GeForce GTX 1080 Ti produces a distinct performance profile. The data shows a system that is capable of high refresh rates at 1080p but quickly becomes GPU-limited as resolution and settings increase, making it a balanced but aging combination for this particular game.

Resolution Scaling

The performance drop from 1080p to 4K is steep, revealing a classic GPU-bound scenario at higher resolutions. At 1080p with Low settings, the combo achieves 155 FPS, but this falls to 107 FPS at 1440p and 63 FPS at 4K. This represents a 31% reduction from 1080p to 1440p, and a further 41% drop from 1440p to 4K. This steep scaling curve indicates that the GeForce GTX 1080 Ti is the primary limiting component at higher resolutions, as the workload on the graphics card increases exponentially with pixel count.

The pattern holds across other settings. At High settings, the average frame rate goes from 88 FPS at 1080p to 61 FPS at 1440p (a 31% drop) and then to 36 FPS at 4K (a 41% drop from 1440p). Similarly, at Medium settings, the sequence is 104 FPS at 1080p, 72 FPS at 1440p, and 42 FPS at 4K. Interestingly, the percentage loss from 1080p to 1440p is nearly identical across Low, Medium, and High settings, which suggests that the scaling is driven almost entirely by resolution rather than by the specific graphical features being toggled.

The shift from 1080p to 1440p is where the experience becomes noticeably less fluid. While 1080p delivers well above 60 FPS at all settings, 1440p dips to 46 FPS at Ultra and 61 FPS at High, making 60 FPS only achievable at Low or Medium. The jump to 4K is even more punishing, with only the Low preset managing to stay above 60 FPS, at 63 FPS. The data indicates that this hardware combination is best suited for 1080p gaming, where it can push high refresh rates, and that 1440p should be reserved for lower quality presets if a smooth frame rate is the priority.

The fact that the performance gap between Low and Ultra is relatively narrow at 1080p (155 FPS vs 67 FPS) compared to the massive resolution-based drops suggests that the CPU, with its strong single-core performance, is able to feed the GPU adequately at lower resolutions. However, as the resolution increases, the GPU's raw pixel-pushing power becomes the bottleneck, and the frame rate collapses accordingly.

GPU Role

The NVIDIA GeForce GTX 1080 Ti is a veteran card with 11 GB of GDDR5X memory on a 352-bit bus, providing 484.4 GB/s of bandwidth. This memory configuration is a double-edged sword in Rust. The 11 GB capacity is ample for the game's large textures and open-world assets, but the memory clock of 1376 MHz (11 Gbps effective) is modest by modern standards. The GPU's core clocks are also dated, with a base of 1481 MHz and a boost of 1582 MHz. These clocks, combined with the 3584 shading units and 88 ROPs, deliver a pixel rate of 139.2 GPixel/s and a texture rate of 354.4 GTexel/s.

In Rust, these specs translate to a card that can handle 1080p and 1440p with ease but struggles to maintain playable frame rates at 4K. The 4K Ultra preset is the most telling case, with an average of just 27 FPS. This is a direct result of the GTX 1080 Ti's fillrate and compute capabilities being overwhelmed by the sheer number of pixels in a 3840x2160 frame. The card's FP32 performance of 11.34 TFLOPS is insufficient for the heavy shading and post-processing work required at that resolution.

The GPU's benchmark scores reflect its mid-pack standing. With a percentile rank of 58 against all GPUs, it sits in the middle of the pack. Its average benchmark score of 15548 is nearly identical to that of the AMD Radeon R9 M380 (15521, deltaPct 0.2%) and the AMD Radeon Pro W5500 (15679, deltaPct -0.8%). It also edges out the NVIDIA GeForce RTX 2060 (15290, deltaPct 1.7%) and the older GeForce GTX 580 (15283, deltaPct 1.7%). This indicates that while the GTX 1080 Ti is not a top-tier performer, it is still competitive with much newer mainstream cards, which explains why it can deliver playable frame rates at 1080p and 1440p in Rust.

The 11 GB VRAM is a significant asset. Even at 4K Ultra, the game is unlikely to exceed this capacity, preventing any memory-related stuttering that could further degrade the already low frame rates. However, the bandwidth is the limiting factor here. The combination of high resolution and high settings demands more data throughput than the card can provide, leading to the performance cliff observed at 4K.

How This Combo Ranks

The Intel Core Ultra 5 245 and GTX 1080 Ti combination ranks 1608 out of 2953 tested combos in Rust. This places it in the 54th percentile of all tested systems, meaning it outperforms slightly more than half of the configurations in the database. This is a respectable position, but it highlights that this is not a top-tier setup for this game, especially when considering that many modern combos will feature much newer GPUs.

The ranking is heavily influenced by the GPU's age. While the CPU is a strong performer, the GTX 1080 Ti holds the combo back, particularly at higher resolutions. The data shows that the system is capable of delivering excellent performance at 1080p, but the rank reflects the overall experience across all resolutions and settings. A combo with a more modern GPU would likely rank significantly higher, even if paired with a slower CPU, because Rust tends to be more GPU-intensive at the resolutions where the game is most demanding.

The CPU's individual percentile rank of 90 against all CPUs is a stark contrast to the GPU's rank of 58. This disparity suggests that the processor is not the bottleneck in most scenarios, and the overall combo rank is dragged down by the graphics card. In fact, the CPU alone is more powerful than what the GPU can leverage, meaning there is headroom for a faster graphics card without encountering a CPU limitation. The rank of 1608 out of 2953 is a clear indicator that while this system is capable of playing Rust, it is not optimized for maximum performance in this title.

Measured FPS Breakdown

The measured FPS data provides a comprehensive look at how this combo performs across various settings and resolutions. At 1080p, the system is clearly GPU-bound at higher settings but can achieve high frame rates at lower ones. The Low preset yields an average of 155 FPS, which drops to 104 FPS at Medium and 88 FPS at High. The Ultra preset produces 67 FPS. At Medium settings, the min FPS is 89 and the max is 120, showing a relatively tight frame time distribution, though the average of 104 FPS suggests some dips occur.

Moving to 2560x1440, the performance becomes more variable. The Low preset still manages a solid 107 FPS, but the Medium preset falls to 72 FPS (with min and max of 61 and 83 respectively). High settings produce 61 FPS, and Ultra drops to 46 FPS. This resolution is the "sweet spot" for this combo if the user is willing to compromise on settings, as 1440p at High just barely misses the 60 FPS mark.

At 4K, the limitations of the GTX 1080 Ti are fully exposed. The Low preset is the only playable option, with an average of 63 FPS. Medium settings drop to 42 FPS, High to 36 FPS, and Ultra to a slideshow-like 27 FPS. The Medium preset at 4K shows a min FPS of 36 and a max of 49, indicating significant frame pacing issues. The data clearly shows that 4K is not a viable option for this combination beyond the absolute lowest settings.

The progression of frame rates across settings is consistent: each step up in quality costs roughly 15-20% of the average FPS. However, the absolute cost of resolution scaling is far more severe, with 4K Ultra delivering only 17% of the frame rate of 1080p Low. This highlights the fundamental balance of the system, where the CPU can handle the game's logic but the GPU is the gatekeeper for visual fidelity.

CPU Role

The Intel Core Ultra 5 245 is a 14-core, 14-thread processor based on the Arrow Lake architecture, built on a 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. This processor is a strong performer, with a percentile rank of 90 against all CPUs and an average benchmark score of 48995. Its nearest rivals include the AMD Ryzen 7 PRO 5755G (49196, deltaPct -0.4%), the AMD Ryzen 9 7900 (49228, deltaPct -0.5%), and the Intel Xeon Gold 5318H (48698, deltaPct 0.6%). It also slightly outperforms the Intel Core i5-14600K (48618, deltaPct 0.8%).

In Rust, the CPU's role is to handle the game's simulation, physics, and entity management. The high boost clock of 5.10 GHz is crucial for single-threaded performance, which Rust heavily relies upon. The single-core benchmark scores are strong, with a Cinebench R23 score of 4648 and a Passmark single-thread score of 4394. These scores indicate that the CPU can keep up with the game's demanding logic at high frame rates.

However, the data shows that the CPU is rarely the limiting factor in this combo. At 1080p Low, the system hits 155 FPS, which reflects the CPU's ability to feed the GPU. Even at 1080p Ultra, the 67 FPS average is likely still CPU-bound in certain scenes, but the GPU is starting to struggle. The fact that the CPU's nearest rivals are all within 1% of its benchmark score suggests that swapping in a similar processor would yield negligible differences in Rust's frame rates, as the GPU is the primary constraint.

The 14 threads are more than sufficient for Rust's multi-threaded tasks, such as world generation and rendering of distant entities. The 24 MB of L3 cache helps with data locality, reducing the need to access main memory. The processor's memory support for DDR5 with a bandwidth of 102.4 GB/s ensures that the GPU has a high-speed data path, though this is not a bottleneck at 1080p. Overall, the CPU is a capable partner that provides ample headroom for the GTX 1080 Ti, but the graphics card limits what the system can ultimately deliver in Rust.
