The AMD 890GX chipset will be the base of the Leo platform together with Phenom II X6
and it will bring an integrated graphics circuit with DX10.1 support and UVD 2.0.
The clock frequency of the IGP is the same, 700MHz, as the current 790GX chipset. http://www.nordichardware.com/en/news/69-cpu--chipset/211-biostar-confirms-890gx-and-phenom-ii-x6-branding.html
In an attempt to provide maximum possible performance for enthusiasts, Advanced Micro Devices plans to implement a dynamic performance boost technology into its six-core processors known as Phenom II X6 “Thuban”. There is a clear trend towards increase of the number of cores inside central processing units (CPUs), just five years ago a dual-core chip was a dream, whereas now we are approaching six-core microprocessors. The software is, unfortunately, seriously behind the hardware and many applications still cannot take advantage of additional cores, but fully depend on clock-speeds. In order to provide maximum possible performance in such programs, developers of CPUs implement special dynamic performance boosting technologies that disable certain cores and overclock the rest.
At present only select Intel Corp.’s microprocessors feature Turbo Boost technology that can accelerate certain cores when they are needed while slowing down the unneeded cores. However, with the introduction of AMD Phenom II X6 “Thuban” processors similar capability will also be available on chips from Advanced Micro Devices, sources close to the company revealed to X-bit labs. http://www.xbitlabs.com/news/cpu/display/20100205073010_AMD_Phenom_II_X6_Thuban_Processors_to_Get_Dynamic_Speed_Boost_Technology.html
