One of Intel’s largest potential customers is one of 3DXP’s biggest skeptics. The chips lack the endurance and the latency to play a significant role in server main memory, said Doug Voigt, a distinguished storage technologist at Hewlett-Packard Enterprise.Full details at EE Times.
At about 20 microseconds in latency, 3DXP is clearly above the two-microsecond upper boundary that Voigt says is a comfort zone for main memory. It is far slower than the 200 nanoseconds of the best main memory pools in today’s servers.
Even memory with latency under a microsecond “will start clogging up your pipeline fairly quickly,” he said. “This is an architectural line of thinking, and I haven’t gotten a lot of pushback on it.”
Intel may be able to lower 3DXP latency somewhat as it refines its manufacturing process. But “it sounds like we’re not there yet, [so] we’ll position it more as storage rather than memory,” he said.
