Rust

Rust paired with the Intel Core Ultra 9 275HX and NVIDIA GeForce RTX 4080 Mobile is a measured configuration with a wide frame-rate spread. The FPS data covers three resolutions and four quality presets, with average results ranging from 36 FPS at 3840x2160 Ultra to 207 FPS at 1920x1080 Low. In the full tested-combo list, this CPU/GPU pair ranks 1167th out of 3723 combinations.

Resolution Scaling

The resolution scaling pattern is clear from the measured data. At Low settings, Rust averages 207 FPS at 1920x1080, 142 FPS at 2560x1440, and 84 FPS at 3840x2160. At High settings, the same sequence is 117 FPS at 1080p, 81 FPS at 1440p, and 48 FPS at 4K. The Medium preset shows 139 FPS at 1080p, 95 FPS at 1440p, and 56 FPS at 4K. Ultra settings produce 89 FPS at 1080p, 61 FPS at 1440p, and 36 FPS at 4K.

Every quality preset follows the same shape: 1080p delivers the highest average, 1440p sits in the middle, and 4K is the slowest. The drop from 1080p to 4K is substantial in all four presets. Since the CPU and GPU remain the same across all of these runs, the changing variable is resolution. The measured behavior indicates that the rendering load, and therefore the GPU, becomes the limiting component as pixel count climbs. At low resolution and low settings, the frame rate is high enough that CPU-side performance also matters, but the consistent resolution penalty points to the graphics pipeline as the main constraint at higher pixel counts.

How This Combo Ranks

The Rust combo ranking places this configuration at 1167 out of 3723 tested CPU/GPU combinations. That is a mid-pack result for this specific game. The CPU alone sits in the 94th percentile of all CPUs, while the GPU sits in the 81st percentile of all GPUs. The aggregate benchmark scores follow the same relationship: the Core Ultra 9 275HX has an average benchmark score of 67,469, and the RTX 4080 Mobile has an average benchmark score of 38,135.

The CPU’s relative standing is stronger than the GPU’s. In this Rust combo list, the pair still lands 1167th, meaning the overall position is influenced by both components. The processor is near the top of the CPU field, but the graphics chip is somewhat further from the top of the GPU field. The measured FPS data reinforces that pattern: at 4K Ultra, the combo averages 36 FPS, which is a GPU-heavy workload, and at 1080p Low it averages 207 FPS, which is closer to a CPU-limited scenario.

GPU Role

The NVIDIA GeForce RTX 4080 Mobile is built around the AD104 chip on TSMC’s 5 nm process. The die contains 35,800 million transistors and measures 294 mm². The GPU has 12 GB of GDDR6 memory on a 192-bit bus, with 432.0 GB/s of bandwidth. The base clock is 1290 MHz, the boost clock is 1665 MHz, and the memory runs at 2250 MHz, rated at 18 Gbps effective. The GPU’s TDP is 110 W, its slot width is listed as IGP, and it connects over PCIe 4.0 x16.

The compute configuration includes 7424 shading units, 232 texture mapping units, 80 ROPs, 58 RT cores, and 232 tensor cores. FP32 throughput is 24.72 TFLOPS, with pixel rate of 133.2 GPixel/s and texture rate of 386.3 GTexel/s. In aggregate benchmarks, the RTX 4080 Mobile scores 38,135, placing it in the 81st percentile of all GPUs. Its nearest rivals in the database are close: it is 0.4% below the NVIDIA GeForce MX570, 0.6% below the NVIDIA GeForce RTX 5080 Mobile, 1.3% above the NVIDIA GeForce RTX 4070, and 1.3% above the NVIDIA Tesla P4. The GPU also records Geekbench OpenCL and Vulkan scores of 159,575 and 145,807, plus PassMark G3D and GPU compute scores of 24,926 and 11,191.

In Rust, the GPU’s role is visible in the resolution scaling. At High settings, the same preset moves from 117 FPS at 1080p to 81 FPS at 1440p and 48 FPS at 4K. At Ultra, it moves from 89 FPS to 61 FPS to 36 FPS. The 12 GB VRAM is present at every measured setting, but the FPS data does not include VRAM usage, so no capacity limit shows directly in the recorded frames. The bandwidth and memory clock figures provide the theoretical memory performance, while the measured frame rates show how that hardware translates into Rust’s actual output.

The Medium preset is the only one with min/max data in the measured set. At 1080p Medium, the average FPS is 139, with a minimum of 118 and maximum of 159. At 1440p Medium, the average FPS is 95, with a minimum of 81 and maximum of 110. At 4K Medium, the average FPS is 56, with a minimum of 48 and maximum of 65. The minimum at 4K Medium is equal to the average at 4K High, which shows how tightly the frame rate can compress at higher resolution.

CPU Role

The Intel Core Ultra 9 275HX is a 24-core, 24-thread Arrow Lake-HX processor with a base clock of 2.70 GHz and a boost clock of 5.40 GHz. It is manufactured on a 3 nm TSMC process with 17,800 million transistors on a 243 mm² die. The cache layout includes 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. The processor supports DDR5 memory over a dual-channel interface with 102.4 GB/s of bandwidth. It connects through PCIe Gen 5 with 20 CPU lanes, has a TDP of 55 W, and includes Arc Xe-LPG Graphics with 64 EU.

The CPU’s benchmark data is strong across both multi-threaded and single-threaded workloads. It scores 35,589 in Cinebench R23 multi-core and 2,204 in Cinebench R23 single-core. In Cinebench R20, it scores 19,899 multi-core and 2,809 single-core. In Cinebench R15, it scores 5,619.5 multi-core and 334 single-core. Geekbench results are 20,795 multi-core and 2,458 single-core. Its average benchmark score is 67,469, which places it in the 94th percentile of all CPUs. Against its nearest rivals, the Core Ultra 9 275HX is 0.3% below the Intel Xeon w5-3525, 0.5% below the AMD EPYC 4484PX, 0.6% below the AMD Ryzen Threadripper PRO 5955WX, and 0.7% above the Intel Xeon 6515P.

In Rust, the CPU’s contribution is most visible in the low-resolution, low-settings result. At 1080p Low, the combo averages 207 FPS. At 1080p Medium, it averages 139 FPS, and at 1080p High it averages 117 FPS. These are frame rates high enough that the CPU’s 24 threads and 5.40 GHz boost clock are part of the platform feeding them. When resolution moves to 4K, the same CPU produces lower average frame rates because the GPU is handling far more pixel work. The CPU’s 94th-percentile standing suggests it is not the weakest part of this combination; the measured Rust results indicate that the graphics subsystem is the primary constraint as resolution and settings increase.
