So far as we know right now:
1. It's going to be cheaper than what Intel is offering for High End Desktop (HEDT) at the same performance.
2. It's going to perform as good as or better than Intel's HEDT offerings which is huge for AMD considering their last 10 years.
3. It's going to have less TDP (Power usage) than some of Intel's HEDT offerings, at 95 watts.
4. It's a System on a Chip so the Motherboard costs will be down compared to similar Intel offerings.
5. The AM4 socket is finally merging APU and CPU sockets into one, and should last at least 4 years if not longer.
6. It supports the latest and greatest connectivity PCI-E Gen 3, m.2 (Solid State Drive connectivity), USB 3.1 Gen 2.
7. Lots and Lots of Motherboards shown off at CES from all the usual vendors, including many small form factor offerings.
8. This is AMDs first Simultaneous Multi-threading (SMT) architecture, so like Intel's Hyperthreading you get two threads for every physical core, and like Intel some SKUs will have this disabled to salvage defective dies.
Benchmarks of engineering samples show it at or beating Intel's $1100 6900K Broadwell-E which is a 8 core 16 thread HEDT CPU, so if AMD prices it's 8c/16t SKU at $500 or less they basically hit a homerun here.
