IBM’s June 2003 newsletter brings information on the new IBM PowerPC 750GX microprocessor, the successor to the company’s 750FX chip (known as the G3 in current iBooks). Manufactured in IBM’s advanced 0.13-micron copper process with Silicon-on-Insulator technology, the 750GX will be offered at frequencies up to 1.1GHz. “The 750GX includes 1MB of internal L2 cache, 4-way set-associative, running at core frequency with cache locking by way, additional L1 and L2 cache buffers allowing pipelining of up to four data cache miss operations, and the capability for up to 200-MHz operation of the 60x system bus interface with additional bus pipelining.” According to IBM, sampling for the new processor is planned for July 2003 with production targeted for December 2003.
