Rust

The Intel Core Ultra 5 125H paired with the AMD Radeon 8050S produces a distinct performance profile in Rust, one defined by the GPU’s role as the primary limiter as resolution climbs. The measured frames per second (FPS) data across three resolutions and four settings presets reveals a system that is highly capable at 1080p, increasingly strained at 1440p, and only marginally playable at 4K. This analysis breaks down those results, interprets the scaling patterns, and places the combination within the broader benchmark database.

Resolution Scaling

The FPS drop from 1920x1080 to 3840x2160 is steep and consistent across all settings, pointing directly at the AMD Radeon 8050S as the bottleneck. At Low settings, the average FPS falls from 135 at 1080p to 93 at 1440p, then to 55 at 4K. That represents a 31% reduction when moving from 1080p to 1440p, and a further 41% reduction when moving from 1440p to 4K. The cumulative drop from 1080p to 4K is 59%, meaning the system loses nearly two-thirds of its frame rate at the highest resolution.

The pattern holds at other presets. At High settings, the average goes from 76 FPS at 1080p to 53 at 1440p, then to 31 at 4K. The 1440p to 4K transition here is a 42% loss, nearly identical to the Low setting’s 41% loss. At Medium settings, the averages are 91, 62, and 37 FPS respectively, with a 40% drop from 1440p to 4K. Ultra settings show the same trend: 58 FPS at 1080p, 40 at 1440p, and 24 at 4K, a 40% loss in the final step.

The consistency of the percentage drops across settings is informative. If the CPU were the limiting factor, we would expect the FPS gap between resolutions to shrink at lower settings, where the GPU has less work to do. Instead, the relative losses remain nearly flat, which indicates the Radeon 8050S is saturated even at Low settings when the resolution increases. The GPU’s pixel rate of 179.2 GPixel/s and texture rate of 358.4 GTexel/s provide the raw throughput, but the data shows that 4K’s 8.3 million pixels overwhelm this particular mobile-class part.

Another way to read the scaling is through the ratio of 1080p to 4K performance. At Low settings, that ratio is 135/55, or roughly 2.45x. At High settings, it is 76/31, or 2.45x again. At Medium and Ultra, the ratios are 91/37 (2.46x) and 58/24 (2.42x) respectively. A perfectly scalable GPU would show a ratio close to 4x (since 4K has four times the pixels of 1080p), but this system delivers only about 2.4x, meaning the GPU is not scaling efficiently and is likely hitting memory bandwidth limits. The Radeon 8050S uses System Shared memory, with bandwidth listed as System Dependent, which explains the shortfall. The CPU’s dual-channel memory bandwidth of 89.6 GB/s is shared between the processor and the integrated graphics, creating a bottleneck that becomes more pronounced at higher resolutions.

Q: How does the 1440p Medium setting compare to the 1080p Medium setting?

A: At 2560x1440 Medium, the average FPS is 62, with a minimum of 53 and a maximum of 72. At 1920x1080 Medium, the average is 91, with a minimum of 77 and a maximum of 104. The 1440p result is 29 FPS lower, a 32% reduction.

Q: Is 4K playable with this combo?

A: The data shows only one 4K preset averages above 30 FPS: Low settings at 55 FPS. Medium averages 37 FPS, High averages 31, and Ultra averages 24. For a survival game like Rust, the 31 FPS High result is borderline, while the 24 FPS Ultra result is below playable thresholds.

Q: What is the best resolution for a smooth experience above 60 FPS?

A: At 1920x1080, three presets exceed 60 FPS: Low (135), Medium (91), and High (76). At 2560x1440, only Low achieves above 60 FPS at 93. No 4K preset reaches 60 FPS.

Q: How does the combo rank among all tested systems in Rust?

A: The combo ranks 2161 out of 2953 tested combinations. This places it in the lower third of the database, indicating that while it can run the game, many other configurations deliver higher frame rates.

Q: What is the minimum FPS recorded in any measured scenario?

A: The lowest average FPS is 24 at 3840x2160 with Ultra settings. The lowest minimum FPS recorded is 31, which appears twice: at 3840x2160 Medium and at 1920x1080 Medium. Note that the 4K Medium minimum of 31 matches the 1080p Medium minimum, despite the 4K average being 37 versus 91 at 1080p.

GPU Role

The AMD Radeon 8050S is a Strix Halo chip built on RDNA 3.5 architecture, using a 4 nm process from TSMC. It operates with a base clock of 1295 MHz and a boost clock of 2800 MHz. The GPU has 2048 shading units, 128 texture mapping units, and 64 render output units, along with 32 ray tracing cores. Its FP32 performance is rated at 11.47 TFLOPS, with FP16 also at 11.47 TFLOPS (1:1). The texture rate is 358.4 GTexel/s, and the pixel rate is 179.2 GPixel/s.

The most significant factor in this game’s results is the memory configuration. The Radeon 8050S does not have dedicated VRAM; its memory size, type, and bus width are all listed as System Shared. This means it relies on the CPU’s memory subsystem, which for the Intel Core Ultra 5 125H is dual-channel DDR5 with a bandwidth of 89.6 GB/s. The GPU’s own memory bandwidth is System Dependent, which in this setup is the same 89.6 GB/s shared pool. This shared bandwidth explains why the FPS scaling from 1080p to 4K is far from ideal. At 4K, the GPU needs to access more texture data and frame buffer data, but the shared memory bus becomes a constraint, capping performance well below what the compute units might otherwise deliver.

The GPU’s benchmark scores corroborate its mid-range positioning. In Geekbench OpenCL, it scores 65818, and in Vulkan, it scores 58398. Its percentile vs all GPUs is 89, meaning it outperforms 89% of the database. The nearest rivals are the AMD Radeon Pro W6600M at 61896 (0.3% lower), the AMD Radeon Pro Vega 56 at 63693 (2.5% higher), the AMD Radeon RX 7600M at 63775 (2.6% higher), and the AMD Radeon RX 9060 XT LP at 63830 (2.7% higher). The 8050S is slightly faster than the Pro W6600M but trails the other three by 2.5-2.7%. This narrow gap suggests that in Rust, the 8050S’s performance is representative of its class, with the shared memory being the main differentiator versus discrete GPUs.

The GPU’s TDP is 55 W, and it is an integrated graphics processor (IGP) with a slot width of IGP. It uses PCIe 5.0 x16 as its bus interface. The 32 ray tracing cores are present, but Rust’s rendering does not heavily rely on ray tracing in these measured presets, so their impact is minimal. Instead, the rasterization throughput and memory bandwidth are the dominant factors. The fact that the 4K High preset only achieves 31 FPS, while the 4K Low preset reaches 55 FPS, indicates that the GPU’s shading units are not the only constraint; the memory subsystem is equally stressed.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend on the target resolution. At 1920x1080, the High preset provides 76 FPS, which is smooth for a survival game. The Medium preset at 91 FPS is also excellent, and the Ultra preset at 58 FPS is slightly below the 60 FPS threshold but still playable. The Low preset at 135 FPS is the highest, but it sacrifices visual quality unnecessarily. For 1080p, High is the best balance, offering a 76 FPS average without the visual degradation of Low.

At 2560x1440, the situation changes. The Low preset is the only one that exceeds 60 FPS, achieving 93 FPS. The Medium preset drops to 62 FPS, which is just above 60, while High falls to 53 FPS and Ultra to 40 FPS. For a consistent 60+ FPS experience at 1440p, Low is the only choice, but players willing to accept 53 FPS can use High for better visuals. The Medium preset at 62 FPS is a viable middle ground, though its minimum FPS of 53 is close to the High preset’s average.

At 3840x2160, no preset reaches 60 FPS. The Low preset at 55 FPS is the most playable, but it is still below 60. The Medium preset at 37 FPS is playable but noticeably less smooth, and High at 31 FPS is borderline. The Ultra preset at 24 FPS is not recommended for any gameplay. For 4K, the data suggests that Low is the only practical setting, and even then, the frame rate is below ideal. The measured minimum FPS at 4K Medium is 31, which matches the High preset’s average, indicating that frame pacing may be inconsistent.

The best experience per the measured rows is at 1920x1080 with High settings, delivering 76 FPS average with no minimum data that suggests drops below 60. At 1440p, the Medium preset at 62 FPS is acceptable, but the minimum of 53 FPS means occasional dips below 60. For users prioritizing frame rate over visuals, the 1080p Low preset at 135 FPS is the smoothest option in the entire dataset.

Measured FPS Breakdown

The full dataset consists of 12 measured rows, covering four settings presets (Low, Medium, High, Ultra) at three resolutions (1920x1080, 2560x1440, 3840x2160). At 1920x1080, the Low preset averages 135 FPS, Medium averages 91 FPS with a minimum of 77 and maximum of 104, High averages 76 FPS, and Ultra averages 58 FPS. The 1080p results show a clear hierarchy, with Low more than double the Ultra frame rate.

At 2560x1440, the averages are 93 FPS for Low, 62 FPS for Medium (min 53, max 72), 53 FPS for High, and 40 FPS for Ultra. The 1440p data shows a smaller gap between presets than at 1080p, with Low being 53 FPS higher than Ultra, compared to 77 FPS higher at 1080p. This narrowing suggests that the GPU is becoming more of a limiting factor as resolution increases, reducing the relative benefit of lower settings.

At 3840x2160, the averages are 55 FPS for Low, 37 FPS for Medium (min 31, max 42), 31 FPS for High, and 24 FPS for Ultra. The 4K results are the most compressed, with Low only 31 FPS higher than Ultra. The minimum FPS at 4K Medium is 31, which means that even the Medium preset can dip to the same level as the High preset’s average. The maximum FPS at 4K Medium is 42, which is lower than the 1080p Ultra average of 58.

Comparing across resolutions, the 1080p Low preset at 135 FPS is the highest score in the entire dataset. The 1440p Low preset at 93 FPS is the second-highest, followed by 1080p Medium at 91. The 4K Ultra preset at 24 FPS is the lowest. The range from best to worst is 111 FPS, from 135 down to 24. The 1080p Medium minimum of 77 FPS is higher than the 1440p High average of 53 FPS, illustrating how much resolution affects performance.

The data also reveals that the 1440p Medium preset (62 FPS) is only 14 FPS lower than the 1080p High preset (76 FPS), but 29 FPS lower than the 1080p Medium preset (91 FPS). This suggests that moving from 1080p to 1440p at Medium costs roughly 29 FPS, while moving from Medium to High at the same resolution costs roughly 9 FPS. The 4K Medium preset (37 FPS) is 25 FPS lower than the 1440p Medium preset, a larger drop than the 1440p to 1080p transition.

CPU Role

The Intel Core Ultra 5 125H is a Meteor Lake architecture processor with 14 cores and 18 threads. It has a base clock of 3.60 GHz and a boost clock of 4.50 GHz, with a TDP of 28 W. The cache hierarchy includes 112 KB of L1 per core, 2 MB of L2 per core, and 18 MB of shared L3 cache. It supports DDR5 memory in a dual-channel configuration with a bandwidth of 89.6 GB/s. The CPU’s integrated graphics are Arc Xe-LPG 96EU, but the system uses the discrete Radeon 8050S GPU.

In Rust, the CPU’s role is secondary to the GPU, as the FPS scaling indicates. The CPU’s Cinebench R23 multi-core score is 12804.5, and its single-core score is 1647.5. The Passmark single-thread score is 3399, and the multithread score is 21100. The CPU’s percentile vs all CPUs is 79, meaning it outperforms 79% of the database. Its nearest rivals are the AMD Ryzen 7 5800 (avg score 27535, 0.1% higher), Intel Core i5-12600K (27578, 0.3% higher), AMD Ryzen 7 5700X (27578, 0.3% higher), and AMD Ryzen 3 PRO 5355G (27382, 0.5% lower). The CPU’s average benchmark score is 27507, which is within 0.5% of all four rivals.

The CPU’s 14 cores and 18 threads are more than sufficient for Rust’s threading model, which typically scales across a few cores. The high single-thread score of 3399 in Passmark indicates strong per-core performance, which is important for game logic and physics. However, the measured FPS data shows that increasing resolution causes larger FPS drops than would be expected if the CPU were the bottleneck. At 1080p Low, the system achieves 135 FPS, which suggests the CPU can feed the GPU at that level. At 4K Low, the FPS drops to 55, a 59% reduction, which is far more than the CPU’s performance would dictate.

The CPU’s memory bandwidth of 89.6 GB/s is a critical shared resource. The Radeon 8050S uses system memory, so the CPU and GPU compete for the same bandwidth. The CPU’s Passmark data compression score is 236209, and its data encryption score is 14251, but these are compute benchmarks that do not directly translate to gaming. The CPU’s L3 cache of 18 MB is shared, which helps with data reuse, but the GPU’s memory demands at higher resolutions likely saturate the memory bus. The CPU’s boost clock of 4.50 GHz provides adequate single-threaded performance, but the system’s overall FPS ceiling in Rust is clearly set by the GPU and its shared memory.

How This Combo Ranks

The combo ranks 2161 out of 2953 tested combinations in Rust, placing it in the 73rd percentile of the database (since 2161/2953 is 73.2%). This means that roughly 73% of tested combos perform better, and 27% perform worse. The rank is not directly tied to the CPU or GPU’s individual percentiles (79th and 89th respectively), which indicates that the combo underperforms relative to what its components might suggest. This discrepancy is likely due to the shared memory architecture, which hurts the GPU’s performance in a memory-intensive game like Rust.

The CPU’s nearest rivals all have similar average benchmark scores, with deltas of -0.1% to -0.3% for the AMD Ryzen 7 5800, Intel Core i5-12600K, and AMD Ryzen 7 5700X, and +0.5% for the AMD Ryzen 3 PRO 5355G. This suggests that the CPU is not the differentiator in this combo’s ranking. Instead, the GPU’s nearest rivals provide context. The Radeon 8050S’s average benchmark score is 62108, which is 0.3% higher than the Radeon Pro W6600M, 2.5% lower than the Radeon Pro Vega 56, 2.6% lower than the Radeon RX 7600M, and 2.7% lower than the Radeon RX 9060 XT LP. The 8050S sits at the bottom of this group, and its shared memory likely causes a larger performance gap in gaming than the benchmark scores suggest.

The combo’s rank of 2161 out of 2953 means it is in the lower third of all tested systems. For a survival game like Rust, where frame rates above 60 FPS are desirable for competitive play, this combo only achieves that at 1080p with Low, Medium, or High settings, and at 1440p with Low settings. The 4K results are all below 60 FPS, with only Low exceeding 50. The data indicates that this is a mid-range mobile combo that can handle Rust at 1080p comfortably but struggles at higher resolutions. The 24 FPS at 4K Ultra is among the lower results in the database, while the 135 FPS at 1080p Low is a solid performance figure. Overall, the combo’s ranking reflects its position as a capable 1080p solution, with diminishing returns as resolution increases.
