# Clearspeed 64-bit CSX600 Co-Processor

Clearspeed upcoming chip, CSX600 code-named Avebury contains 96 separate internal units tuned for doing particular types of math problems. The CSX600 is designed as a co-processor for accelerating PC’s, workstations, servers, clusters, and blades eg. Intel or AMD based. Initial applications are expected to be in life sciences, financial modeling, geophysical computation, scientific computing, military and aviation among others. Avebury runs at 250MHz and coasts on 5 watts. But with its 96 processing cores, it can churn 50 billion floating point operations (math problems that involve a decimal point) per second. If a single processing element burns out or fails to work, the remaining 95 will continue to function. Samples of Avebury now exist. CSX-600 will come out in the first quarter of 2005. A workstation that contains a dual-Avebury card will likely cost around $ 50,000.
