$ phoronix-test-suite benchmark ramspeed
RAMspeed tests the system memory (RAM) performance. With the exception of the N100 mini PC, all the machines are running dual-channel memory.
The MS-02 Ultra delivers strong RAMspeed SMP results, but the figures need context. The system is fitted with DDR5-5600 SODIMMs, but the motherboard runs them at 4800 MT/s. Even with that restriction, the MS-02 Ultra essentially matches the Core Ultra 9 285H system and edges ahead of the Core Ultra 7 255H. It trails the Ryzen 9 7940HS and Ryzen 9 8945HS machines by around 9 to 11%, a gap that’s likely influenced heavily by the lower operating memory speed. The Ryzen AI 9 HX 370 is in a different league, topping 50 GB/s and leading the rest of the field by a wide margin. Older DDR4-based systems sit well behind the DDR5 machines, while the single-channel N100 result highlights how much memory channel configuration affects bandwidth
$ phoronix-test-suite benchmark tinymembench
This benchmark also tests the system memory (RAM) performance. memcpy() copies a block of memory from one location to another. memset() fills a block of memory with a specified byte value.
Tinymembench tells a noticeably different story from RAMspeed. While RAMspeed favours the Ryzen AI 9 HX 370 and broadly tracks raw memory bandwidth, tinymembench is more sensitive to the CPU’s actual memory copy and fill paths. In memcpy, the MS-02 Ultra tops the chart despite its DDR5-5600 SODIMMs running at 4800 MT/s. That result reflects the efficiency of the platform’s copy behaviour rather than a simple raw memory speed advantage. The memset test is even more Intel-favourable, with the Core Ultra 7 255H and Core Ultra 9 285H leading the field and the MS-02 Ultra close behind.
The Ryzen systems that performed strongly in RAMspeed fall back here, showing that tinymembench is testing a different aspect of memory performance: practical copy and fill throughput rather than pure multi-threaded memory bandwidth.
