From Wikipedia, the free encyclopedia

AMD K10 is AMD's tenth-generation microarchitecture. It is the successor of AMD K8. AMD K10 includes Athlon X2, Athlon II, Phenom, Phenom II, and Opteron microprocessors. It is AMD's second 64 bit microarchitecture. The Phenom and Athlon processors compete with Intel Core 2 and Intel Core i7/5/3. The Opteron processors compete with Intel Xeon. AMD K10 processors have been produced for sockets AM2+, AM3, and F.

Background

[edit]

In 2003, AMD outlined the features for upcoming generations of microprocessors after K8 family of processors in various events and analyst meetings, including the Microprocessor Forum 2003 [1]. The first K10 based processor launched was the Barcelona Opterons on September 10, 2007. The first consumer K10 microprocessor was the Phenom, launched on November 19, 2007.

Features

[edit]

AMD introduced the microprocessors manufactured at 65 nm feature width using Silicon-on-insulator (SOI) technology, since the release of K10 coincides with the volume ramp of this manufacturing process [2]. The servers were produced for Socket F(1207) or later 1207-pin socket infrastructure, the only server socket on AMD's near-term roadmap; the desktop parts first came on Socket AM2+ and were backwards compatible to AM2. Later, after shifting to 45 nm consumer CPU's were released on Socket AM3 with backward compatibility to AM2+ and AM2.

The first K10 based processors used DDR2 memory. DDR3 support was added in socket AM3 chips.

Processor Cores

[edit]

Opteron

[edit]

Opterons are targeted at servers. Opteron cores based on K10 include Barcelona, Shanghai, and Istanbul.

Phenom

[edit]

AMD Phenoms were the first AMD quad core processors targeted at consumers. Chip harvesting was used to produce the Phenom X3 series with one disabled core.

Athlon

[edit]

Kuma Athlons are Phenoms with 2 disabled cores.

Phenom II

[edit]

Phenom II is AMD's first 45nm consumer part. Originally released for Socket AM2+ with Phenom II X4 940 and 920 processors, all later models are for Socket AM3. X3 and X2 version are made by Chip Harvesting Black Edition Phenom II's have an unlocked multiplier and have been overclocked to more than 7GHz.

Athlon II

[edit]

Athlon II's are like Phenom II's but with no L3 cache. Athlon II X3's are made by chip harvesting but not the X2 version. AMD has confirmed that some Athlon II's will be Phenom II's with disabled L3 cache.
