Ampere has given an update to the next server processor top model with the code name Altra Max, which will appear with 128 CPU cores in the course of this year – 48 more than the fastest Altra processor Q80-33 so far. The basic architecture based on Arms Neoverse-N1 design remains the same, as well as the CPU-Fang LGA4926 used – the 128-kerners fit in previous mainboards.
However, ampere uses the interconnect to keep the latencies within the nuclear network (mesh-interconnect) potentially low. First manufacturer’s own benchmarks compare the new 128 kerners with the 3.0 GHz fast 80-kernel Q80-30
Manufacturer benchmarks for the 128-sensor Altra Max show high performance scaling compared to their own 80-nuclear.
The new top model Hort on the name M128-30: the "M" stands for Altra Max, the 128 for the number of CPU cores and the 30 usually for the clock frequency – here also 3.0 GHz. Ampere has measured a performance plus of 57 percent in encoding with AES-256-GCM. In video encoding with H.264 codec was the M128-30 55 percent faster; The web server software NGINX ran 51 percent thread. The distance to Q80-33 was allowed to fail slightly lower due to the clock difference of 300 MHz.
Octa Channel with DDR4-3200
There are no changes in memory expansion with eight channels for up to 4 TBYTE DDR4-3200 SDRAM. For expansion cards and additional chips are 128 PCI Express 4.0-lanes ready. Poupling two processors in dual-socket mainboards to each other, staying 192 PCIe-4.0-LANES UNBRIG.
Amperes blog post for performance does not come from about about, because AMD has presented the third EPYYS generation 7003 Alias Milan, with which the Altra-CPUs compete. Although Milan offers only half as many CPU cores, but more computing power per core and also 128 threads thanks to Simultaneous Multithreaading (SMT). Intel was allowed to follow in short with the fourth Xeon Scalable Generation ICE Lake-SP.
