Intel's Haswell-E processors already pack as many as eight cores and 16 threads, but the next generation of the company's extreme desktop CPUs could offer more multi-threaded goodness yet. Chinese site Xfastest claims to have gotten its hands on a juicy document with the specifications of Intel's Broadwell-E desktop chips.
If that information is correct, the Broadwell-E desktop lineup may include six-core, 12-thread chips called the Core i7-6800K and i7-6850K, an eight-core, 16-thread chip called the Core i7-6900K, and a Core i7-6950X with a whopping 10 cores and 20 threads.
Those numbers may sound crazy for a single-socket CPU, but Intel's consumer -E chips are derived from Xeon-EP silicon. Haswell-EP Xeons already ship with anywhere from eight to 18 cores and 16 to 36 threads. Broadwell-EP processors are reportedly in development with core counts similar to or higher than Haswell-EP. Intel's product team would probably only need to say "make it so" in order to bring a 10-core, 20-thread Broadwell-E product to market.
Going by the remainder of Xfastest's information, these next-gen chips will use the same LGA-2011v3 socket as Haswell-E chips, but it's unclear whether the X99 chipset will soldier on with Broadwell-E. Intel hasn't released any official information on Broadwell-E or the accompanying platform yet, so we'll have to see whether Xfastest's info holds up.
