Rust

The Intel Core Ultra 5 245 paired with the AMD Radeon RX 6600 XT lands in the lower-middle portion of the database for Rust, holding the 2091st spot out of 2953 tested combinations. That placement places this combo in roughly the 29th percentile of all systems tested in this title, meaning nearly three-quarters of the tested configurations deliver higher average frame rates. The pairing is not a top-tier performer, but the rank reflects a balanced mid-range setup rather than a severely bottlenecked one, as the measured frame rates across resolutions show a consistent, predictable scaling pattern. The combo is closer to the bottom of the pack at 4K, where the GPU struggles to maintain playable numbers, but it climbs meaningfully as resolution drops, suggesting the pairing is far more competitive in the 1080p segment where most Rust sessions will realistically run.

GPU Role

The AMD Radeon RX 6600 XT carries the primary rendering workload in this configuration, and its specifications explain much of the observed behavior in Rust. The GPU is built on the RDNA 2.0 architecture using the Navi 23 chip, fabricated on a 7 nm process at TSMC, with 11,060 million transistors on a 237 mm² die. The memory subsystem consists of 8 GB of GDDR6 on a 128-bit bus, delivering 256.0 GB/s of bandwidth, which is a modest allocation for a modern survival title that frequently streams in large world assets. The core clock speeds are reasonably strong for the class, with a base of 1968 MHz, a game clock of 2359 MHz, and a boost clock of 2589 MHz, allowing the GPU to push through lighter scenes without stalling. The RX 6600 XT includes 2048 shading units, 128 texture mapping units, and 64 render output units, along with 32 ray tracing cores, though Rust does not heavily utilize ray tracing in its standard rendering path.

The GPU’s overall standing in the database is the 70th percentile among all GPUs, with an average benchmark score of 24442. Its nearest rivals in aggregate performance include the NVIDIA GeForce GTX 1630 (0.7% higher), the Intel Arc A350M (0.8% lower), the NVIDIA GeForce GTX 780 Ti (0.8% higher), and the NVIDIA GeForce RTX 2080 SUPER (1.1% higher). This tight clustering indicates that the RX 6600 XT sits in a competitive band where small architectural differences determine the winner, and in Rust specifically, the GPU’s 8 GB frame buffer becomes a limiting factor at higher resolutions and settings. The measured results show the GPU handling 1080p with room to spare, but the 4K Ultra preset falls to an average of 24 FPS, a figure that points directly at the VRAM capacity and memory bandwidth constraints rather than compute throughput limitations. The pixel rate of 165.7 GPixel/s and texture rate of 331.4 GTexel/s are adequate for the lower resolutions, but the 128-bit memory interface remains the weakest link in demanding scenes.

Resolution Scaling

The frame rate progression from 1080p to 4K in Rust reveals a clear GPU-bound trajectory for this combo, with the CPU holding its own until the render resolution climbs. At the Low preset, the average FPS moves from 138 at 1920x1080 down to 95 at 2560x1440, then to 56 at 3840x2160, representing a 31% drop from 1080p to 1440p and a further 41% drop from 1440p to 4K. This steep decline indicates that even at the lowest settings, the RX 6600 XT is the limiting factor, as the CPU has enough headroom to feed the GPU at 1080p but the GPU cannot sustain the pixel throughput at higher resolutions. At the Medium preset, the scaling shows a similar pattern: 92 FPS at 1080p, 64 FPS at 1440p, and 37 FPS at 4K, with the 1080p to 1440p drop of 30% and the 1440p to 4K drop of 42% reinforcing the GPU-bound nature of the configuration.

The High preset follows the same trend, with 78 FPS at 1080p, 54 FPS at 1440p, and 32 FPS at 4K, though the percentage drops are slightly more moderate at 31% and 41%, respectively. The Ultra preset is the most demanding, starting at 59 FPS at 1080p, falling to 41 FPS at 1440p, and collapsing to 24 FPS at 4K, with the 1080p to 1440p reduction of 31% and the 1440p to 4K reduction of 41% matching the other presets almost exactly. This consistent scaling pattern across all four settings presets strongly suggests that the rendering resolution is the dominant factor in performance, and the CPU is not introducing a significant bottleneck at any point. The data indicates that at 1080p, the combo can deliver smooth gameplay even on High settings, but at 1440p, users will need to drop to Low or Medium to maintain acceptable frame rates, while 4K is only viable on the Low preset with a marginal 56 FPS average.

Settings Recommendations

Based on the measured rows, the optimal balance of visual fidelity and frame rate for this combo in Rust depends heavily on the target resolution, but the data points to the Medium preset as the best overall choice for most users. At 1920x1080, the Medium preset delivers an average of 92 FPS with a minimum of 78 FPS and a maximum of 106 FPS, which provides a smooth experience that comfortably exceeds the 60 FPS threshold for competitive play. The High preset at the same resolution yields 78 FPS, which is still playable but with less headroom for demanding scenes, while the Ultra preset drops to 59 FPS, landing just below the 60 FPS target and potentially causing stutter in busy areas. The Low preset at 1080p produces 138 FPS, but the visual quality loss is substantial, making Medium the sweet spot for those who want both responsiveness and acceptable graphics.

At 2560x1440, the Medium preset is again the recommended starting point, with an average of 64 FPS and a minimum of 54 FPS, which is playable but requires some tolerance for occasional dips in intense firefights. The High preset at 1440p drops to 54 FPS, which is borderline for fast-paced gameplay, while the Low preset provides 95 FPS and is the only setting that offers a comfortable margin above 60 FPS at this resolution. For 4K, the situation is more constrained, with the Low preset delivering 56 FPS as the only viable option, while the Medium preset falls to 37 FPS and High drops to 32 FPS, both of which are too low for a smooth experience in a survival game where reaction times matter. The Ultra preset at any resolution is not recommended, as even at 1080p it only reaches 59 FPS, and at 1440p and 4K it falls to 41 FPS and 24 FPS, respectively, making it the worst value in terms of performance per visual gain.

Measured FPS Breakdown

The complete set of measured frame rates for this combo in Rust shows a clear hierarchy across resolutions and settings. At 1920x1080, the Low preset achieves an average of 138 FPS, the Medium preset reaches 92 FPS with a minimum of 78 FPS and a maximum of 106 FPS, the High preset delivers 78 FPS, and the Ultra preset produces 59 FPS. The progression from Low to Ultra at 1080p shows a 57% reduction in average frame rate, which is a substantial cost for the highest visual settings, but the 59 FPS floor at Ultra is still technically playable. At 2560x1440, the Low preset averages 95 FPS, the Medium preset averages 64 FPS with a minimum of 54 FPS and a maximum of 73 FPS, the High preset averages 54 FPS, and the Ultra preset averages 41 FPS. The drop from 1080p to 1440p at each settings tier is consistent, with the Low preset losing 31% of its performance, the Medium preset losing 30%, the High preset losing 31%, and the Ultra preset losing 31%, confirming that the GPU is scaling evenly with resolution.

At 3840x2160, the Low preset averages 56 FPS, the Medium preset averages 37 FPS with a minimum of 32 FPS and a maximum of 43 FPS, the High preset averages 32 FPS, and the Ultra preset averages 24 FPS. The 4K results are uniformly low, with even the Low preset barely reaching 60 FPS, and the Ultra preset falling to 24 FPS, which is below the threshold for acceptable playability. The minimum frame rate data is only available for the Medium preset at each resolution, showing 78 FPS at 1080p, 54 FPS at 1440p, and 32 FPS at 4K, which suggests that the Medium preset has the most stable frame delivery among the settings tested. The maximum frame rates at Medium are 106 FPS at 1080p, 73 FPS at 1440p, and 43 FPS at 4K, indicating that even in lighter scenes, the 4K resolution cannot push beyond 43 FPS, reinforcing the GPU’s memory bandwidth as the primary constraint.

CPU Role

The Intel Core Ultra 5 245 serves as the processing backbone for this combo, and its specifications indicate that it is not the limiting factor in Rust’s performance at most tested settings. The CPU features 14 cores and 14 threads, with a base clock of 3.50 GHz and a boost clock of 5.10 GHz, built on the Arrow Lake architecture using a 3 nm process at TSMC. The cache hierarchy includes 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache, which provides adequate data locality for the game’s simulation and entity update loops. The CPU supports DDR5 memory with a dual-channel bus and a bandwidth of 102.4 GB/s, along with PCIe Gen 5 with 20 lanes for the CPU, though the RX 6600 XT uses a PCIe 4.0 x8 interface, which does not bottleneck the GPU in this title. The processor’s 65 W TDP and integrated Arc Xe-LPG Graphics 64EU are secondary considerations, as Rust relies on the discrete GPU for rendering.

The CPU’s benchmark results place it in the 90th percentile among all processors, with an average benchmark score of 48995, and its nearest rivals include the AMD Ryzen 7 PRO 5755G (0.4% lower), the AMD Ryzen 9 7900 (0.5% lower), the Intel Xeon Gold 5318H (0.6% higher), and the Intel Core i5-14600K (0.8% higher). In multi-threaded workloads, the CPU scores 32924 in Cinebench R23 multi-core and 13828 in Cinebench R20 multi-core, while single-thread performance reaches 4648 in Cinebench R23 and 1952 in Cinebench R20. Passmark results show a multithread score of 38706 and a single-thread score of 4394, with the physics score at 2569, which is relevant for Rust’s physics-heavy interactions. The data strongly suggests that the CPU can easily feed the RX 6600 XT at 1080p, as the frame rates at Low settings reach 138 FPS without any indication of CPU saturation, and the consistent scaling across resolutions points to the GPU as the performance ceiling. The CPU’s 14 threads are sufficient for Rust’s multi-threaded server and simulation code, and the high single-thread boost clock of 5.10 GHz ensures that the main game loop does not become a bottleneck even in populated servers.
