Intel yesterday demonstrated the next step forwards its Xeon CPU line will take with its eight-core, 16 thread Nehalem-EX processor.

The chip giant said that Nehalem-EX will enter production later this year and will feature eight cores, 16 threads and a whopping 24MB of cache packed into a mere 2.3 billion transistors manufactured using Intel’s 45nm high-k metal gate process technology.

In addition, Nehalem-EX will add new reliability, availability and serviceability (RAS) features, such as Machine Check Architecture (MCA) Recovery, which is traditionally only found in Intel’s Itanium family of CPUs.

There are also four high-bandwidth QPI links, enabling up to eight processors to work together in one system for a total of 128 threads.

Intel set up a demo with IBM to show 128 processing threads working in one system – you can watch that demo below, where all 128 threads are pegged at 100 per cent utilisation. The company also said that scalability to 32 sockets was also possible, but this hasn’t been demonstrated yet.
