Back in January, we read that AMD was planning to launch a 3.1GHz Phenom II X4 950 processor in the mid-second-quarter. Today, HKPEC quotes sources at motherboard makers as saying AMD has cancelled that chip—and, because of better-than-expected yields, the company will instead release the 3.2GHz Phenom II X4 955 in April.
According to HKEPC, the Phenom II X4 955 will have the same 125W power envelope and 8MB of total cache as the current top-of-the-line Phenom II. However, it will be 200MHz faster, and it will be a Socket AM3 part with support for DDR3-1333 memory. (The current Phenom II X4 940 only works with DDR2.)
In addition, HKEPC echoes the rumors of dual-core Phenom IIs we heard last month. The site says AMD is prepping 3GHz Phenom II X2 545 and 3.1GHz Phenom II X2 550 processors for launch in mid-May. Both chips will be based on Callisto, which is supposedly the quad-core Deneb die with two cores disabled. That means each chip should have 6MB of shared L3 cache and 512KB of L2 cache per core.
