AMD Opteron A1100 Technology Report

The AMD Opteron A1100 Technology Report

AMD today officially launched the AMD Opteron A1100 System-on-Chip (SoC). Formerly codenamed “Seattle“, the AMD Opteron A1100 is the first AMD device to use the 64-bit ARMv8-A processor microarchitecture, instead of the usual x86 microarchitecture.

The ARMv8-A microarchitecture allows for a more energy-efficient device, but their unfamiliarity with it may have been the reason why the Opteron A1100 was delayed almost 18 months.Today’s launch marks the end of that protracted development process.

 

The AMD Opteron A1100 Revealed

The AMD Opteron A1100 was designed around the ARM Cortex-A57 processor cores to deliver better power efficiency and lower costs. Coupled with enterprise-class features, AMD is hoping that it will allow them to penetrate the datacenter or hyperscale computing market.

The AMD Opteron A1100 processor will feature up to 8 ARM Cortex-A57 processor cores, backed by up to 4 MB of shared L2 cache and a large 8 MB L3 cache. Its dual-channel memory controller supports up to 128 GB of DDR3 or DDR4 memory.

Connectivity-wise, it supports two 1o Gb Ethernet ports, a single PCI Express 3.0 slot and up to 14 SATA3 devices. Take a look at the Opteron A1100 chip diagram

Here are the market segments that AMD plans to target with the Opteron A1100 SoC. Basically anyone who wants a cheap, efficient SoC for massive deployments.

To support those solutions, AMD has already prepared a complete solution stack. This is what probably took them so long to qualify the Opteron A1100 for the enterprise market.

In the next page, we will take a look at the three new Opteron A1100 models AMD launched today… Click here!

AMD Opteron A1100 Model & Package Details

AMD will initially offer 3 models – the AMD Opteron A1170, the AMD Opteron A1150 and the AMD Opteron A1120. Here are their key specifications :

Whether they come with 4 or 8 processor cores, all Opteron A1100 processors will have the same SP1 package, because they are all the same chip. The quad-core models will just have half the cores disabled.

AMD Opteron A1100 Memory Support

To cater to the enterprise market, the AMD Opteron A1100 will support both DDR3 and DDR4 memory in three different interfaces – UDIMM, RDIMM and SO-DIMM.

Basically, the AMD Opteron A1100 will support memory speeds up to 1866 MHz for DDR4 memory, and 1600 MHz for DDR3 memory. You can run them in single- or dual-channel modes using up to 4 memory modules.
