X-bit Labs received word 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 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).
Also expected on September 21 are the dual-core AMD Phenom II X2 560 (3.3GHz, 7MB cache) and quad-core AMD Athlon II X4 645 (3.1GHz, 2MB L2 cache), both chips are expected to cost around $100.
