AMD: Customers Demand More Cores
"In looking through sales data for the first half of 2010, 12-core processors clearly outsold their 8-core counterparts -- by a wide margin," AMD's John Fruehe said. "I was expecting that there would be a slight bias towards the 12-core, but I figured there were plenty of applications where the extra clockspeed of an 8-core might be popular. Apparently, I was wrong, customers are voting with their budgets, and cores matter."
AMD's 12-core chips consist of two of these 6-core Istanbul parts
The way Fruehe sees it, as much as AMD would like to take credit for this phenomenon, the trend towards 12-core chips is really "just an indicator that the business world is hungry for more cores." And forget about bragging rights, in the business world, having more cores comes in handy for more than posting on your favorite forum the highest synthetic score you can achieve.
"Many customers have told me that they have a rule of 'one VM per core,' so with 12-core processors, their consolidation can get even denser," Fruehe explains. "With 24 cores in a 2P server, there are plenty of resources to allow all of the VMs to have plenty of access to compute power whenever they need it."
Other areas Fruehe sees 12-core processors becoming a popular option is in large databases and high performance computing, like Switzerland's new Cray XE6 supercomputer. This awesome system uses AMD 8- and 12-core chips to crunch through 12.2 to 20.2 teraflops per system cabinent.
"So, when it comes to core counts, our customers are sending a pretty clear signal us: Cores Matter. That message is very good to hear because next year will see 16 total cores in our Bulldozer-based products," Fruehe said.
What do you think is the current core-count 'sweet spot'? Are you looking forward to having more cores on the desktop, or is the hardware getting too far ahead of the software?
