Rust

The Intel Core Ultra 5 245 and AMD Radeon RX 6600 combination ranks 2280th out of 2953 tested combos in Rust, placing it in the lower-middle tier of the database. This percentile position is notable because the CPU itself sits in the 90th percentile among all processors, while the GPU lands in the 63rd percentile. The discrepancy between component rankings and the final combo ranking suggests that Rust's performance ceiling for this pairing is dictated heavily by the graphics card, not the processor. The data implies that users with this setup are leaving potential performance on the table, as the CPU has significant headroom to drive a more powerful GPU in this specific title.

The combo's position becomes clearer when examining the component-level benchmarks. The Core Ultra 5 245 achieves an average benchmark score of 48995, which is nearly identical to its nearest rivals: it trails the AMD Ryzen 7 PRO 5755G by just 0.4 percent and the AMD Ryzen 9 7900 by 0.5 percent, while leading the Intel Xeon Gold 5318H by 0.6 percent and the Intel Core i5-14600K by 0.8 percent. This tight clustering indicates that the CPU is performing exactly as expected for its class. The RX 6600, conversely, shows a more scattered competitive landscape, with its average score of 19036 matching the NVIDIA Quadro K6000 within 0.0 percent, edging out the RTX 4050 Mobile by 0.1 percent, and trailing the Tesla K20m by 0.3 percent. The GPU is competitive at its level, but that level is fundamentally lower than what the CPU can support.

GPU Role

The AMD Radeon RX 6600 brings 8 GB of GDDR6 memory on a 128-bit bus, delivering 224.0 GB/s of bandwidth. Its clock behavior is defined by a base of 1626 MHz, a game clock of 2044 MHz, and a boost clock of 2491 MHz, with memory running at 1750 MHz or 14 Gbps effective. These specifications translate to 1792 shading units, 112 texture mapping units, and 64 ROPs, producing a pixel rate of 159.4 GPixel/s and a texture rate of 279.0 GTexel/s. The card achieves 8.928 TFLOPS of FP32 performance, which is the raw compute figure that scales directly with the frame rates observed in Rust.

In the context of Rust's measured results, the GPU's 8 GB capacity appears sufficient for the tested settings, but the bandwidth and compute limits become visible at higher resolutions. The 224.0 GB/s memory bandwidth is a modest figure for 2025 standards, and the data shows this constraint manifesting as a steep performance cliff when moving from 1440p to 4K. The 64 ROPs are also a limiting factor for pixel-heavy workloads like Rust, which relies on large draw distances and complex lighting. The card's RDNA 2.0 architecture supports DirectX 12 Ultimate, which Rust can leverage, but the measured FPS suggests the implementation does not fully compensate for the hardware's raw throughput limitations.

The GPU's benchmark profile reinforces its midrange positioning. Its PassMark G3D score of 15096 and DirectX 12 score of 51 indicate solid but not exceptional DirectX 12 performance, which is relevant since Rust's modern rendering path will exercise this API. The Geekbench Vulkan score of 67623 is notably higher than the OpenCL score of 28850, suggesting the architecture favors Vulkan workloads, which could matter if Rust's renderer takes advantage of this API path. The 3DMark Steel Nomad DX12 score of 1492 provides a synthetic reference point that aligns with the GPU's 63rd percentile ranking among all graphics cards.

Resolution Scaling

The measured FPS data reveals a consistent and predictable scaling pattern across the three tested resolutions. At 1080p Low, the combo achieves 126 FPS, which drops to 87 FPS at 1440p Low and further to 51 FPS at 4K Low. This represents a 31 percent decrease from 1080p to 1440p and a 41 percent decrease from 1440p to 4K at the Low preset. The scaling at High settings follows a similar trajectory: 71 FPS at 1080p, 49 FPS at 1440p, and 29 FPS at 4K, with percentage drops of 31 percent and 41 percent respectively. This consistent 30-40 percent reduction per resolution step indicates that the GPU is the primary bottleneck at all settings, as a CPU-bound scenario would show smaller FPS differences between resolutions.

The Medium preset provides the most complete data set, with min and max FPS values recorded for each resolution. At 1080p Medium, the average is 85 FPS with a range of 72 to 97 FPS. Moving to 1440p Medium drops the average to 58 FPS with a range of 49 to 67 FPS, and 4K Medium falls to 34 FPS with a range of 29 to 40 FPS. The consistent 31-32 percent drop between each resolution step at Medium settings reinforces the GPU-bound nature of this pairing. The Ultra preset shows the steepest absolute declines: 54 FPS at 1080p, 37 FPS at 1440p, and 22 FPS at 4K, representing 31 percent and 41 percent drops respectively, matching the pattern seen at other settings.

This scaling behavior has a clear implication for the limiting component. If the CPU were the bottleneck, the FPS would remain relatively flat across resolutions because the processor's workload does not scale with pixel count. Instead, the consistent 30-40 percent FPS reductions as resolution increases point directly to the RX 6600's pixel throughput capabilities being the constraining factor. The 5.10 GHz boost clock of the Core Ultra 5 245 is more than sufficient to feed frames at these rates; the GPU simply cannot render them faster at higher resolutions.

Measured FPS Breakdown

At 1920x1080, the combo demonstrates its strongest performance. The Low preset delivers 126 FPS on average, which is the highest figure recorded across all configurations in this test. Medium settings produce 85 FPS with a minimum of 72 and maximum of 97 FPS, indicating smooth frame pacing with only a 15 percent variance between the lowest and highest measured frames. High settings drop to 71 FPS, and Ultra falls to 54 FPS. The jump from Low to Medium costs 41 FPS, while the jump from Medium to High costs 14 FPS, and from High to Ultra costs 17 FPS. This suggests that the Low preset is not fully utilizing the hardware, while the Ultra preset pushes the GPU to its limits.

Moving to 2560x1440, the performance landscape shifts downward. Low settings still deliver a playable 87 FPS, but Medium drops to 58 FPS with a range of 49 to 67 FPS, High reaches 49 FPS, and Ultra falls to 37 FPS. The variance at Medium settings is 18 FPS, slightly wider than at 1080p, which indicates more frame time inconsistency as the GPU works harder. The difference between Low and Medium at 1440p is 29 FPS, while Medium to High costs 9 FPS, and High to Ultra costs 12 FPS. The smaller deltas between higher presets at 1440p compared to 1080p suggest the GPU is becoming more saturated and individual settings have less relative impact.

At 3840x2160, the combo struggles to maintain playable frame rates. Low settings produce 51 FPS, which is borderline acceptable, but Medium drops to 34 FPS with a range of 29 to 40 FPS, High falls to 29 FPS, and Ultra bottoms out at 22 FPS. The 4K Medium variance of 11 FPS is the smallest in absolute terms but represents a 32 percent swing relative to the average, indicating significant frame pacing issues. The progression from Low to Medium at 4K costs 17 FPS, Medium to High costs 5 FPS, and High to Ultra costs 7 FPS. These diminishing returns at higher presets confirm that the GPU is completely maxed out at this resolution, and further quality increases yield minimal visual improvement for substantial performance loss.

CPU Role

The Intel Core Ultra 5 245 features 14 cores and 14 threads, with a base clock of 3.50 GHz and a boost clock of 5.10 GHz. This configuration is unique in that it lacks hyper-threading, making the thread count equal to the core count. The CPU is built on TSMC's 3 nm process with Arrow Lake architecture, featuring a 24 MB shared L3 cache and 3 MB L2 per core. Its memory support is DDR5 with dual-channel configuration and 102.4 GB/s bandwidth, which is adequate for feeding the GPU but not exceptional. The processor's PassMark multithread score of 38706 and single-thread score of 4394 place it in the 90th percentile of all CPUs, confirming strong performance for gaming workloads.

In Rust, the CPU's role is less critical than the GPU's, as evidenced by the resolution scaling data. However, the processor's capabilities still set the upper bound for achievable frame rates. The 1080p Low result of 126 FPS demonstrates that the CPU can drive high frame rates when the GPU is not the bottleneck. The single-thread performance of 4394 in PassMark is particularly relevant for Rust, which historically has had a significant single-threaded component to its engine. The Cinebench R23 single-core score of 4648 and multi-core score of 32924 further validate the CPU's strength in both lightly and heavily threaded scenarios.

The CPU's performance relative to its rivals shows it is well-positioned. Its average benchmark score of 48995 is within one percent of the AMD Ryzen 7 PRO 5755G, AMD Ryzen 9 7900, Intel Xeon Gold 5318H, and Intel Core i5-14600K. This clustering indicates that the Core Ultra 5 245 is performing at the expected level for a modern mid-range to upper-midrange processor. The 90th percentile ranking reinforces this, showing that the CPU is in the top decile of all processors in the database. For Rust specifically, this means the CPU will not be the limiting factor in most scenarios, leaving the GPU as the primary determinant of frame rates.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend heavily on the target resolution and desired frame rate. At 1080p, the Medium preset offers the best balance of visual quality and performance. The 85 FPS average with a range of 72 to 97 FPS provides smooth gameplay for most users, while the High preset at 71 FPS is also viable if visual fidelity is prioritized. The Ultra preset at 54 FPS is playable but may feel less fluid in fast-paced combat scenarios. The Low preset at 126 FPS is excessive for most displays, as it exceeds the refresh rate of typical 1080p monitors, making Medium the recommended choice for maximizing visual quality without sacrificing smoothness.

At 1440p, the Low preset at 87 FPS is the only setting that provides consistently smooth gameplay. Medium at 58 FPS is borderline, with the 49 to 67 FPS range indicating that some scenes will dip below 60 FPS. High at 49 FPS and Ultra at 37 FPS are both below the 60 FPS threshold and will exhibit noticeable stuttering in demanding scenes. For 1440p users, sticking with Low settings is the safest recommendation to maintain a playable experience, though Medium can be considered if the user is willing to accept occasional frame drops.

At 4K, none of the tested presets provide a fully smooth experience. The Low preset at 51 FPS is the only configuration above 30 FPS, making it the only viable option for those who must play at 4K. Medium at 34 FPS and High at 29 FPS are both below 30 FPS and will feel sluggish, while Ultra at 22 FPS is essentially unplayable. For 4K users, the data strongly suggests that this combination is not suitable for the resolution, and dropping to 1440p or 1080p is necessary for a good experience. The measured data shows that the RX 6600 lacks the compute and bandwidth to handle Rust at 4K with playable frame rates, regardless of preset selection.
