The colleagues over at X-bit Labs report that AMD will introduce a couple of new processors on September 21st, 2010. This includes a new six-core chip clocked at 3.0GHz and also a multiplier unlocked 3.5GHz quad-core.

“The two key processors set to be announced are AMD Phenom II X6 1075T (3.0GHz/3.50GHz TurboCore with 9MB of cache) and AMD Phenom II X4 970 Black Edition (3.50GHz, 8MB of cache). The first will cost in the range between $230 – $240 and will broaden the line of code-named Thuban microprocessors, whereas the second will be AMD’s fastest quad-core microprocessor with the price tag that is likely to be below $200.

Considering the fact that TurboCore clock-speed of the six-core model 1075T will be 3.50GHz, the difference in price between it and the quad-core Phenom II X4 970 BE should be considerable as the chips have equal performance in applications that require up to four threads (in order to avoid internal competition between six-core and quad-core products).”

Alongside these processors on September 21 a dual-core AMD Phenom II X2 560 (3.3GHz, 7MB cache) and quad-core AMD Athlon II X4 645 (3.1GHz, 2MB L2 cache) are expected as well, both to cost roughly $100.

Much like Intel decided to go for the per core overclokcing feature ‘Turbo boost’ AMD apprantly also will follow that trend by enabling a new feature called Dynamic Performance Boost for the upcoming Thuban (hexacore) processors.

The “Thuban” architecture is based on 45nm architecture and will feature an integrated DDR2/DDR3 controller. The chip is based on AMD’s six-core Opteron chip. It is expected that the piece will be called Phenom II X6.

The dynamic performance boost technology is currently known as “C-state performance boost” and will supposedly be able to detect when single-threaded operation is needed, or vice verse when multiple threads are active.

The idle CPU cores will be automatically disabled and the clocks of the ones used will be boosted to as high a level as possible. The limit will be determined by the general thermal design power.

We certainly can’t wait to see the all new Phenom II X6 “Thuban” series processors likely somewhere in April / May.

AMD has updated schedule to phase out several Phenom II X4 900 series CPUs, while launch a new model in 2010, according to sources in the motherboard industry.

AMD has already stopped taking orders for Phenom II X4 910 (2.6GHz/95W) and 945 (3.0GHz/125W) CPU in fourth-quarter 2009 and will completely stop shipments in the second quarter of 2010.

The company will stop order placements for Phenom II X4 965 (3.4GHz/140W) and 925 (2.8GHz/95W) CPUs in the first quarter of 2010, while orders for the Phenom II X4 955 (3.2GHz/125W) are scheduled to end in the second quarter. In the second quarter of 2010, AMD will launch a 95W Phenom II X4 955 processor.

In addition to the Phenom II X4 900 series, AMD will also stop taking orders for several Phenom II X4 800, X3 700, X2 500, Athlon II X4 600, X3 400 series CPUs next year, leaving the Phenom II X4 820, Phenom II X3 740 and Phenom II X2 550 in its lineup. AMD will launch the 80W Phenom II X2 555 later in fourth-quarter 2009, and the 95W Athlon II X4 640 and 95W Athlon II X2 445 in the second quarter of 2010.

In additional news, AMD will also bring forward the launch of its six-core desktop CPU codenamed Thuban to the second quarter of 2010. Thuban adopts a 45nm process and socket AM3 packaging, while featuring six 512KB L2 cache, 6MB L3 cache, and a core frequency of 2.8GHz.

AMD reduced prices of several Phenom II and Athlon II CPUs: Phenom II X4 965 dropped from US$245 to US$195, Phenom II X4 955 from US$245 to US$175, Athlon II X2 250 from US$87 to US$69 and Athlon II X2 245 from US$66 to US$64, according to the company.
