Hercules shrugged: raw speed is no match for this hydra's many-headed power, and with 512 cores, the Grape DR math coprocessor's got heads to spare. The University of Tokyo's 500 Mhz chip can, despite the slow clock, churn out 512 billion FPU operations per second, with a stunning 2 quadrillion operations hoped for in future revisions.
Measuring 1.7cm, it uses 300m transistors and gobbles 60W of power.

While we mere mortals are all happy with our dual-core processors and all excited about the upcoming quad-core processors, several researchers from Tokyo University are secretly snickering at us. But of course, they have all the right to do so since they invented a 512-core processor known as the Grape DR chip.
To be accurate, the processor is not a replacement for our favorite Intels and AMDs, but sits on a PCI-X card providing number-crunching power. Even though the processor runs at just 500MHz, it is capable of delivering 512GLOPS (512 billion floating-point operations every second). To put things into perspective, our modern processors are only capable of performing at a few GFLOPS.
The 512 cores are split into 16 groups of 32, each group capable of processing a single type of FP instruction. The chip itself measures 17 x 17mm and contains 300m transistors. It consumes up to 60W of power.
The researchers actually started working on this project since 2004. By 2008, they hope to accomplish a prototype capable of delivering 2PFLOPS (two quadrillion floating-point operations a second, 3906.25 times faster than 512GLOPS).

Researchers at the University of Tokyo have developed a processor that uses 512 cores to achieve up to 512 billion floating point operations per second.
Dubbed "Grape DR", the processor is designed for use as a math co-processor, rather than a central processing unit. The Grape DR integrates into a host system on a PCI express slot and performs specific tasks such as floating-point addition or multiplication. Despite the fact that the processor is clocked at only 500 Mhz, it is able to calculate over 512 billion floating-point operations per second, more than double the 256 billion operations that IBM’s Cell Processor can theoretically achieve.
The 512 cores in the processor are divided in to 16 groups of 32. Each group of cores is capable of calculating a specific type of mathematical function, i.e. multiplication, addition, etc. Even with so many operations taking place the Grape DR is still a relatively enviro-friendly processor, consuming only 60 Watts of power at peak usage.
Despite the exceptional achievement of the Grape DR, which University researchers began work on in 2004, the project is far from over. The next step in the project is to develop a processor capable of 2 Petaflops, about four times faster than the current Grape DR. The university hopes to have this version of the processor working by 2008.
