AMD Rome Second Generation EPYC Review: 2x 64-core Benchmarked
As with all the comment, this really is EPYC. And we have a roadmap of Zen 3 and Zen 4 in the next two years. Zen 3 will likely be some enhancement of Zen 2 with 7nm EUV, Zen 4 will be DDR <i>5</i>, PCIe <i>5</i>.0 and <i>5</i> nm ,likely some more IPC improvement and I/O Die improvement.<p>The way I see it is that CPU performance for most of my needs has reached the tipping point. Unless something unexpected happen the performance per dollar in the next few years are only going to increase. I would not be surprised to see 128 Core / 256 Threads in Single Socket by 2021 / 2022.<p>The question I have in my head now, when will DRAM price drop to the point, where I have 64 Core EPYC Server with 4TB of Memory and call it a day. While there are some insanely large dataset, for possibly 90% of the Web DB I doubt we have a Database that is 4TB large. And it could all be in Memory. But even at $10 /GB, which is very low already for a 256GB DIMM Stick, 4TB is like $40K
