Antares PowerPC G5 970MP dual-core?

Think Secret has posted an article outlining a rumoured IBM "Antares" processor. It is reported to be a dual-core version of the 970FX, with 1 MB L2 cache per core (versus 512 KB on the 970FX), as well as Altivec. The rumoured time frame for its rollout is sometime in 2005, with a clock speed of 3 GHz.

The original discussion is here, and the description of the rumoured chip is as follows:

The IBM PowerPC 970MP RISC Microprocessor is a dual-core, 64-bit implementation of the IBM PowerPC ® family of reduced instruction set computer (RISC) microprocessors that are based on the PowerPC
Architecture. This dual microprocessor, also called the PowerPC 970MP, includes a Vector/SIMD facility which supports high-bandwidth data processing and compute-intensive operations. The 970MP is also designed to support multiple system organizations, including desktop and low-end server applications, up through 4-way SMP configurations.
Note: The IBM PowerPC 970MP incorporates two complete microprocessors on a single chip, along with some common logic to connect these microprocessors to a system.

No mention is made of an integrated memory controller. An integrated memory controller is something many have been predicting for the next generation G5, but for a desktop it may not really be necessary. It may be more desirable for laptops however, to reduce overall power consumption.
