I can't imagine that the i860 can > actually perform as well as 340MByte/sec since the Hub-Link (between > the MCH and the P64H) has a limit of 266MByte/sec (AFAIK) .... The data sheet for the i860 shows 3 separate Hub-links A, B and C. A is 266 MByte/sec (and typically runs the 33 Mhz 32 bit stuff). B and C are 533 MByte/sec each and drive the P64Hs. (16 bits * 66 Mhz * 4x data xfers). http://developer.intel.com/design/chipsets/datashts/290713.htm The pdf is about 1.1 MB.
