Report: Intels Haswell-E Processor to Support DDR4 Memory
The upcoming ultra high-end Haswell-E processor will reportedly have support for DDR4 RAM.
Intel is reportedly developing an ultra high-end processor that they've codenamed "Haswell-E." It will replace the Ivy Bridge-E, a CPU that hasn't even been released yet but is expected to arrive in Q3 2013.
According to Fudzilla, the Haswell-E will have from 12 to 16 cores, a TDP of 130 W, and support for DDR4 memory that promises to deliver exponentially more bandwidth than previous generations of processors.
Given that none of these details have been finalized and that DDR4 memory is still far from being finalized or produced, we're somewhat skeptical of this report and are interested in seeing how much of it actually turns out to be true.
What just happened? oO
Do they wanted to write 6 cores and 8 cores (so 12 threads and 16 threads)? This is a serious jump from 6 cores to 12-16 if this is true...

Intel's current Xeon E7 lineup has 10 models featuring 10 cores and 20 threads: http://www.intel.com/content/www/us/en/processor-comparison/compare-intel-processors.html?select=server
The lowest-end 10-core Xeon (E7-2850) had a $2558 launch price tag; roughly 8X the price of an i7-3770.
And there is the Xeon Phi which has up to 60 cores and 240 threads.
That stuff was produced before the DDR4 specification was finalized (which happened in September 2012). There doesn't have to be a specification for people to produce some prototypes, indeed the specification probably takes lessons learned from prototypes into account.
Sigh... the GDDR5 used in graphics card is a modified version of DDR3 memory. DDR4 is newer and more advanced than GDDR5. Most likely they'll later develop a GDDR6 based on DDR4.

Actually, GDDR5 is based on GDDR4 and GDDR3, which were based on DDR2.
RE this "report", we've known this for ages...
All of the details have been finalized, they just haven't been made public yet. Fudzilla is wrong in implying that "consumers" will get 12-16 cores. That'll be the higher end versions of the chip. -E will still be 6 cores...maybe 8 depending on what business decision the higher ups make.
