Penryn (Wolfdale and Yorkfiled)???

Hello all,
I was shopping for a new mobo and ran across some that only support the Penryn (Wolfdale and Yorkfiled).

What is a Penryn (Wolfdale and Yorkfiled)?

Thanks in advance.

Wolfdale is the dual core Penryn CPU for dual socket servers (successor to Woodcrest). Yorkfield is the Penryn version of the desktop single socket quad core (Core 2 Quad). It's possible the Wolfdale could run on a single socket motherboard, although I'm not aware of any examples. A motherboard which supports one of themwould likelyalso support the older equivalent version, possibly with reduced FSB rating, but their seems little point in buying a new motherboardif you don't intend to use the new CPU it was designed for.

For applications which exercise memory bandwidth, the higher available Penryn FSB rating (1333Mt/s forYorkfield, 1600 for dual socket Wolfdale dual core and Harpertown quad core)oftengives more advantage than the other performance improvements.

Penryn also features major improvements in performance for a few instructions, notably divide and square root, as well assome new instructions (SSE 4.1). Yes, as they are all multi-core, they do support threaded applications.
