Hi Josef,

The performance loss from lack of support for critical word first bursting is significant. But, considering an access typically requires about 8 cycles (at 133 Mhz) before presentation of the first word to the CPU, overlapping of access cycles, aggressive OOO capabilities and the typical success rate of prefetch during high bandwidth phases of execution, not nearly what one might think.

Anyway, AMD will hopefully address this issue with the integrated NorthBridge of Sledgehammer.

Re: BTW, this (not sending the critical word to the CPU) seems to be the CPU issue...

Well, you may have hit upon one of the "easy" performance increases that could come as soon as next quarter from Mustang.

Regards,

Dan
