Quad Core Battle : Intel Yorkfield vs AMD Altair

Yorkfield Extreme Edition based on the 45nm Penry core architecture will meet
heads-on with AMD Altair based on the 65nm K8L core in Q3 2007. Both are quad
core offerings but AMD touted theirs to be a native quad-core with dedicated
512KB L2 cache for each core and an additional 2MB L3 cache for the 4 cores to
share. Intel has different plans for Yorkfield. Instead of sharing L2 cache for
all the cores, the L2 cache size is further increased. Due to its advanced 45nm
process technology, Yorkfield XE is able to pack a total of 12MB L2 cache (2 x
6MB L2) and still achieving a much smaller die size. The clock speed is
significantly higher at 3.46-3.74GHz too. Yorkfield will feature Penryn New Instructions (PNI) or more officially known
as SSE4 with 50 more new instructions. Yorkfield XE will pair up nicely with the
Bearlake-X chipset supporting DDR3 1333, PCI Express 2.0 and ICH9x coming in the
Q3 ’07 timeframe as well.

eventually but it seems like AMD has packed more innovations into their K8L
architecture while Intel moving onto 45nm process benefits its Yorkfield greatly
in terms of lower power consumption, higher clock speed and a much bigger L2
cache. Certainly it is exciting ahead of us.
