Fujitsu Touts 'World's Fastest' CPU


Fujitsu Touts 'World's Fastest' CPU

Fujitsu's SPARC64 VIIIfx processor might not have the most inspiring of names, but what it lacks in charisma it makes up for in sheer performance. Touted as the world's fastest CPU, the chip is capable of a blistering 128 gigaFLOPS - one hell of a lot of computational throughput.

The SPARC64 VIIIfx features eight cores and an integrated memory controller, in a die around 2cm square. Fujitsu also reckons that its CPU uses about a third less power than Intel's fastest, while offering about 2.5 times the processing ability.

Built on a 45nm fabrication process, the CPU will apparently be used in next-generation supercomputer installations, dealing with weather, transportation, medical and space systems. Such applications are able to take advantage of the huge throughput capability of the SPARC64 VIIIfx in a manner than, say, your average Windows user wouldn't.

The downside, for those in apposition to use such a CPU, is that the transition from the processor demonstrated in the lab to real-world products is going to take a few years.

That looks larger than 2cm....unless these Fujitsu people have very small hands...

@Stewart, I've a feeling the picture is just showing you the chip container, IOW: on the other side they are the pins etc. The CPU itself will be much smaller.

@Stewart Payne - I'm guessing that's a heatspreader!

@ Stewart - The 2cm figure the die size, not the size of the chip itself, but nonetheless it does indeed look very big.

P.S. - it's 'sheer', not 'shear' ;)

I blame Microsoft Word ;)

@Stuart: Maybe Fujitsu only employ children?
