I was amused that the heroic efforts by Intel to make AMD looks bad included a 1 horse power (735 watts) pump in the cooler.
So sure Intel can make 32 cores go fast, by taking a $10,000 chip (literally, it's a relabel of the Intel Xeon 8180), a giant power supply, impressive cooling, and a 735 watt pump. Still only has 75% of the memory bandwidth/memory channels of the AMD epyc.
My main hope with threadripper is that they hit the lower price points that the HEDT intel chips do (I.e. $300-$500).

- sliken 8y agoYeah, that's the one I have my eye on. Was hoping for something more competitive with the i7-7800x or so (6 core, 12 threads, 4 memory channels, 4 GHz, and $390 list).
- loeg 8y agoThey're pretty similar, but I think 1900x is slightly higher end. (And arguably, better value if you can utilize all the cores.) i7-7800x (Skylake-X) is a sort-of last gen part (Kabylake-X briefly existed in the form of i7-7740X, although only in a 4-core SKU); 4 GHz is its maximum turbo clock (may be only single core); base clock is 3.5. 1900x is current gen, although about to become last-gen; its base clock is 3.8, 4.0 turbo (single core). Same number of memory channels. 33% more cores. AMD's IPC lags Intel a little bit, but not by 25%. Is it worth the $60 (15%) premium? Maybe. When TR2's version of 1900x comes out, TR1 1900x may experience a nice price drop, making it (even) more competitive/affordable.
