Freescale Drives Embedded Multicore Innovation with New QorIQ Advanced Multiprocessing SeriesIn summary:
   - announces new E6500 64bit core
   - multithreaded (2 threads per core)
   - up to 2.5Ghz clock rate
   - 28nm process
   - Altivec
   - first chip is 12 core/24thread beast, T4240
   - availability "early 2012" - typical Freescale
Looks like a good next-generation candidate for the X1000 series. By the time these are mature the timing should be about right.
Quoting directly from press release:
The AMP series consists of three levels of products within a scalable portfolio, initially spanning from ultra-high-performance processors featuring 24 virtual cores down to single-core products. 
Control plane processors (service provider routers, storage networks) 
Up to 6 cores running at up to 2.5 GHz 
Greater than 6 MB L2 cache 
High-end data plane processors (routers, switches, access gateways, mil/aero applications) 
Up to 24 virtual cores running at up to 2.0 GHz 
50 Gbps IP forwarding capability 
Advanced application acceleration 
Low-end data plane processors (media gateways, network attached storage, integrated services router)  Up to 8 virtual cores running up to 1.6 GHz 
Advanced application acceleration 
Less than 10W power 
Freescale's first product in the QorIQ AMP series, the T4240 device, integrates a host of hardware accelerators with 12 dual-threaded e6500 cores, providing 24 threads to address high-end data plane processing applications. Dual-threaded efficiency, improved DMIPs per thread and higher frequency deliver 4x performance gain and more than 2x power efficiency gain over the previous-generation QorIQ P4080 device. Advanced capabilities allow for intelligent sharing and duplication of resources between threads and a larger amount of on-die cache per core. Application examples for the T4240 device include metro carrier edge routers, access gateways and aerospace/defense products. Freescale will provide more details regarding the T4240 product later this year. The device is planned for initial availability in early 2012.
