According to Anandtech, Intel will be releasing a new dual core processor, code named Yonah in early 2006. Yonah is the successor to the notebook Pentium M processor, which is very efficient for chess playing programs. If you go to http://www.geocities.com/sedatchess/hardware.html, I believe the Pentium M is the only Intel processor to break the top 10 of that list. Looking at the details of the Anandtech article at http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2627&p=3 it looks like the L2 cache latency has increased significantly : **************************************************************************** "And changed they have indeed. If you’ll remember from our earlier desktop Pentium M investigations, Dothan’s very quick 10 cycle L2 cache allowed it to be competitive with AMD’s Athlon 64, despite lacking an on-die memory controller. With the move to Yonah however, the L2 cache latency has gone up a whopping 40%. While we’re still dealing with a lower access latency than the Pentium 4, this increase will hurt Yonah." **************************************************************************** So, my question to hardware experts is - what will the impact be on chess programs of a significant increase in L2 cache latency ??
