AMD Phenom II X6 models revealed

Intel might have won the race to get the first six-core desktop CPU out of the doors, but AMD looks set to introduce not one, but three of its own six-core chips in just a few months.

We already know that AMD’s forthcoming hexacore chips will have the umbrella name of Phenom II X6, but a leaked roadmap on ATI Forum (Google Translation) has just revealed that three versions of the chip will probably be doing the rounds.

At the top end of the scale is the Phenom II X6 1075T, which will apparently have a TDP of 125W. Then, at the lower end sits the Phenom II X6 1035T with a TDP of 95W. Meanwhile, the Phenom II X6 1055T sits in between the two. There’s no word on clock speeds yet, but another slide on ATI Forum shows that the six-core 1000-series CPUs will probably have 9MB of cache.

This makes sense, given that you get 8MB of cache in the current line-up of Phenom II X4 900-series of CPUs. If the roadmap is genuine, then we’d imagine that the Phenom II X6 chips will have six blocks of 512KB Level 2 cache (one for each core), plus a shared 6MB pool of Level 3 cache.

In addition to the three six-core chips, the roadmap also reveals that another quad-core chip could also be released in the same timeframe. According to the slide, the Phenom II X4 960T will have a TDP of 95W.

According to the roadmap, all three Phenom II X6 CPUs are scheduled to be released in the middle of the second quarter of this year. This means we could see the first six-core AMD desktop CPUs as early as May 2010.
