AMD Phenom II X4 840 and 975: two weeks later

On January 4th at CES show in Las Vegas AMD announced three new desktop microprocessors - quad-core Phenom II X4 840 and 975, and hexa-core 1065T. Quite a few hardware review sites posted reviews of two quad-core Phenom IIs. Two weeks later, boxed versions of Phenom II models are not yet available anywhere in the US.

Phenom II X4 840 is the first "Phenom II" branded model without level 3 cache. Specifications this CPU are identical to Athlon II X4 650, that was supposed to launch in December 2010: 3.2 GHz clock frequency, 4 cores with 512 KB L2 cache per each core, DDR3 memory support, 95 Watt Thermal Design Power, and standard set of integrated CPU features, including SSE3 extensions and Virtualization technology. The 840 model was not referenced in AMD blog announcement, although it is included on the AMD Phenom II Processor Model Number and Feature Comparisons page. It is possible that the Phenom II 840 is an Athlon II 650, rebranded at the last minute. We think that some Athlon II 650 parts did ship to OEM builders, as this model can ordered in HP Pavilion Elite HPE-500z series dekstop PC.

Phenom II X4 975 is the new AMD flagship quad-core model, clocked at 3.6 GHz. This model superseded Phenom II 970, which was running 100 MHz slower. Like the 970, the 975 is offered as a Black Edition, and can be easily overclocked by changing clock multiplier in BIOS. CPU features 6 MB L3 cache, and has the same 125 Watt TDP as the Phenom II 970. The rest of the features is indistinguishable from processors from Phenom II 9xx series.

Phenom II X6 1065T is the fastest six-core AMD processor, that fits 95 Watt thermal envelope. The processor has 2.9 GHz clock frequency, which can be upped to 3.4 GHz when 3 or more cores are idle. The CPU has newer core revision E0, and comes with 6 MB of level 3 cache. Before the announcement, this model already emerged in OEM systems from Mouse Computer. The processor is also shipped in HP Pavilion Elite HPE-560z series desktop PCs. While it's impossible to find this model in US stores, there are several 1065T chips listed on eBay.

The 1065t processor is very attractive, anyone know why it's not in shops yet ? I mean it was introduced the same time as the 1100t, which is available, but I don't need that kind of power especially at 125W...
