Russia Beats China in Creating First Home-grown CPUThis post was edited by Zirco at 2015-8-14 21:27
The Russian company MCST (Moscow Center for SPARC Technologies) has released the Elbrus-4C, a reasonably high-performance quad-core CPU that may grant Russia some technological independence from American chip-making giants Intel and AMD.
Despite the company's name, the Elbrus-4C uses the Elbrus ISA (instruction set architecture), not SPARC. Elbrus is a closed and proprietary architecture, so exact details are hard to come by, but we do know about one particularly interesting feature: x86 emulation. If you remember the Transmeta Crusoe, it sounds like the Elbrus architecture does something very similar: at run-time, x86 program code can be translated and executed through a virtual machine. This method isn't as fast as providing x86 support in hardware, but it gets the job done.
The Elbrus-4C, while highly advanced by home-grown Russian standards, is by no means a bleeding-edge chip; it's a quad-core part built on TSMC's last-last-generation 65nm process. It's capable of hitting a rather heady clockspeed of 800MHz, which equates to (a fairly decent) 25 gigaflops of 64-bit double-precision math. The tech specs say that the Elbrus-4C has 986 million transistors, which is pretty hefty considering there's no integrated GPU. All in all, Elbrus-4C is probably a few years behind western chips, but it's difficult to make a direct comparison.
There's operating system support, too: MCST is selling a complete computer (confusingly called an Elbrus ARM-401) that comes with an Elbrus-compatible Linux distro called—you guessed it—Elbrus. The ARM-401 product page says it also supports Windows XP and other x86-compatible operating systems through the CPU's x86 abstraction layer.
Pricing on the Elbrus-4C is unknown, but a report by the Russian website Kommersant says the chip is "cheaper" than chips out of the US.
Updated: One website pegs the price of the ARM-401 (i.e. a complete computer based on the Elbrus-4C) at 200,000 rubles (~$4,000), but it will be "significantly reduced" by the end of the year.
In recent years, there has been a marked move by countries such as Russia and China to use home-grown chips, rather than continuing to rely on American technology. While China's latest-and-greatest supercomputer Tianhe-2 uses Intel chips, the country has also started building smaller supercomputers based on the country's own MIPS-based Loongson CPUs. Russia has stated that it would like to build a home-grown exascale supercomputer by 2020, but it isn't clear if Elbrus chips will be used.
Russia and China must increasingly come together in the future. And you lads need to get yourself a 2017 calendar: lool This post was edited by tenderloin at 2017-8-14 10:37
Loongson latest is 28nm, and is widely used in China.
