AMD Phenom II X6 1055T - HDT55TWFK6DGR / HDT55TWFGRBOX
Specifications
Although pre-launch news stories speculated about possible launch of up to 5 six-core processors, 1035T, 1055T, 1075T and 1090T, only two of them were introduced on April 27 - 1055T with 125W Thermal Design Power (TDP) and 1090T Black Edition. Around May 10, AMD posted information on the third member of six-core Phenom II family - model 1055T with 95 Watt TDP. As stated by AMD website, the processor will be offered in OEM and Boxed versions. It's expected that 1055T 95 Watt version will have the same price as 125 Watt version.
Phenom II X6 1055T with thermal Design Power 95 Watt is the third member of six-core Phenom II family. The processor is built on K10 micro-architecture, and has six cores, integrated memory controller and shared 6MB level 3 cache on a single die. Each core in 1055T model has its own 128 KB level 1 and 256 KB level 2 cache. Integrated memory controller works with DDR2 and DDR3 memory, and to communicate with on-board and peripheral devices the CPU uses one HyperTransport 3 link. The 1055T runs at 2.8 GHz, and incorporates standard Phenom II features - 64-bit instructions, SIMD extensions up to SSE3, Enhanced Virus Protection, and Virtualization. New feature in this processor is Turbo Core. This feature temporary increases core frequency of up to three cores when remaining cores are not utilized. The processor is packaged in 938-pin micro-PGA package, which is compatible with socket AM3 motherboards, and, with appropriate BIOS support, socket AM2+ motherboards.

Is there a specific launch date for the 1055t 95 TDP CPU? cause i have to order a computer soon (next 2-3 weeks)and i couln`t find the described statement on the amd homepage
Thx for any help
Response: The processor is listed on products.amd.com. I think at this time these parts are shipped only to OEMs. I don't know when the boxed 1055T 95W processors will start shipping.

Thx for your help, hope it`s not going to be that long till they release the boxed version. OEM is fine with me, as long as my local dealer can order OEM CPUs,i am using an diffrent cooler anyway.
I got mine :D
