The tiger is out of its cage. AMD has pulled the curtain off a new mainstream notebook platform, which it code-named Tigris and now stamps with the Vision Technology badge. This platform brings with it eight processors based on 45-nm process technology—AMD's first in the mobile space—alongside a new RS880M integrated graphics chipset.
Here's what the new mobile processor lineup looks like:
|Model name||Cores||Clock speed||L2 Cache||TDP|
|Turion II Ultra M640||2||2.6 GHz||2 MB||35 W|
|Turion II Ultra M620||2||2.5 GHz||2 MB||35 W|
|Turion II Ultra M600||2||2.4 GHz||2 MB||35 W|
|Turion II M520||2||2.3 GHz||1 MB||35 W|
|Turion II M500||2||2.2 GHz||1 MB||35 W|
|Athlon II M320||2||2.1 GHz||1 MB||35 W|
|Athlon II M300||2||2 GHz||1 MB||35 W|
|Sempron M100||1||2 GHz||512 KB||25 W|
AMD differentiates these CPUs in other, less obvious ways. According to the 2009 AMD Mainstream Notebook Platform page on the company's website, the Athlon II and Sempron parts have half-width (64-bit) floating-point units and lower HyperTransport interface speeds (3.2GT/s instead of 3.6GT/s). Unless we're mistaken, though, all eight chips are derived from the same 45-nm Caspian silicon.
Global availability of notebooks based on this platform should "coincide with the forthcoming release of the Microsoft Windows 7 Operating System." (Windows 7 will launch on October 22.) AMD expects over 50 designs, and it adds that some of them have already been available in "certain Asian countries" since September 2.
AMD Marketing VP Pat Moorehead has provided a sneak peek at one of those designs on his blog. The 16" laptop has a Turion II Ultra M640 processor, Radeon HD 4200 integrated graphics, four gigs of RAM, and a 1366x768 display resolution. Moorehead boasts about the notebook's GPU-assisted video encoding performance, its high-definition video decoding and enhancement features, and its improved gaming performance compared to last year's Puma platform.
