Six-core chips on Intel's roadmap
- 14 February, 2010 22:00
Intel is preparing six-core chips for high-end desktops and servers for release in the first half of this year, the company says.
The six-core chips will be based on the company's latest Westmere architecture and deliver faster performance and more power savings compared to earlier quad-core chips. The chips will contain 1.17 billion transistors and include 12MB of cache, a company spokesman says.
The new chips are made using the 32-nanometer process, which is also used to make the company's latest Core processors introduced last month. The base architecture of both the chips are the same, but the six-core chips will not include integrated graphics capabilities. Users will need to buy a discrete graphics card to work with the chips.
Intel officials declined to provide further details such as clock speed.
It is targeting desktop six-core processors, code-named Gulftown, at enthusiasts like gamers. The processor will fit into the same socket as the older quad-core Core i7. The Gulftown processor will come under the Core i7 brand name and be able to run 12 threads at the same time to boost application performance.
Intel already offers a six-core Xeon processor code-named Dunnington. The new six-core Westmere-EP chip will also be offered under the Xeon brand name, but it includes speed and security enhancements. Intel CEO Paul Otellini said in late January that Intel would release Xeon chips made using the 32-nm within three months.
For servers, Westmere also adds a new instruction set for faster data encryption and decryption called Advanced Encryption Standard. That could help secure data residing in servers or virtualised environments.
In addition, the six-core processors include new power management technologies for the chips to be power efficient. For example, the chips will be capable of shutting down idle cores to save power.
The company is also preparing an eight-core chip code-named Nehalem-EX, which is Intel's fastest processor to date, Otellini says. The chip is also due for release in the first half of this year.
AMD also plans to come out with a six-core chip for high-end desktops code-named Thuban, though it hasn't officially announced the shipping date for it.
