2021: E252-P31, G242-Р33, G242-P34, R152-P31, R152-P32, R272-P31, R272-P32 и R272-P33
On November 26, 2021, Gigabyte, a manufacturer of servers, computers and components, announced a line of servers with Ampere processors.
According to the company, the Gigabyte line includes eight server models with indexes E252-P31, G242-P33, G242-P34, R152-P31, R152-P32, R272-P31, R272-P32 and R272-P33. Ampere development chips work in each of them, with computing cores in the amount of 32 to 80.
According to the official Gigabyte website, the servers are built on the processors of the Ampere Altra line, which debuted in the spring of 2020.
All eight servers are designed for installation in the rack - there are no tower models in this series. Six of them are of type 2U, and only two (R152-P31 and R152-P32) fit in a thin 1U housing.
Processors used in Gigabyte servers are manufactured using a 7nm process. Depending on the number of cores, their TDP (amount of thermal power removal) reaches 210 W.
The processors are based on the ARMv8.2 + architecture with a number of changes borrowed from ARM 8.4 and 8.3. Chips can operate at frequencies up to 3 GHz. Each has 64 KB of L1 cache and L2 cache is 1 MB per core. The L3 cache reaches 32 MB.
Ampere processors meet the requirements for DDR4-3200 RAM (four to eight channels available). The maximum volume is 4 TB. They also have up to 128 PCIe 4.0 lines in assemblies on one CPU, and if the server has space for two processors, then the total number of lines will increase to 192.
During the announcement of their chips, representatives of Ampere did not fail to compare Altra with the then current Intel server CPU and AMD. AMD Epyc 7742 and Intel Xeon Platinum 8280 were selected as rivals, both of which lose to Altra in terms of performance.
Ampere also compared energy efficiency. ARM processors always consume less power than x86. AMD Epyc 7702 and Intel Xeon Platinum 8276 participated in the test. They turned out to be "grittier" than Altra 1.14 and 2.11 times.
The line of Gigabyte servers with Ampere processors can be divided into three sub-series. The first, which includes models with the letter G in the title, is aimed at optimizing the load on the video subsystem. From two to four Nvidia video accelerators can be installed in it, plus three more slots for other expansion cards will remain. They are powered by two 80 Plus Platinum power supplies of 1.6 kW each.
Models R152-P31, R152-P32, R272-P31, R272-P32 and R272-P33 are general purpose servers in 1U and 2U form factors, and the last E252-P31 is an Edge server. Power supplies in them have power from 650 W to 1.2 kW, depending on the model.
All servers, like the processors used in them, support up to 4 TB of DDR4-3200 RAM. Each model has 16 slots for these bars.
If necessary, servers can be equipped with two M.2 SSD drives that support the PCIe Gen4 x4 interface. Separately, there is room for 2.5 and 3.5-inch drives in the amount of four to 12 pcs[1]
