Intel does not seem to care about AMD, they think they can do no wrong. They think their name is a houseold word (it sort of is) Have they dropped 9900k prices when the 3800x came out ? No. Its still king of gaming (most of the time) by a very slim margin, so they go on that.
Threadripper just kills their HEDT offerings most of the time, but the TR 3000 series will make it all the time (except avx512, very niece of a niece), because its Rome with 4 channel memory, NOT like the 2990wx thats memory handicapped. I paid $2700 for 2 2990wx's and thats getting good deals. So I figure thats about whjat the market will bear. $2700-3000.
I don't think Threadripper is even doing much at all with regards to hurting Intel's HEDT stuff as most of that is OEM workstations and AMD I don't think has any of that market (which is absurd, and yet another reason I think AMD needs to shift their entire company into making complete platforms since OEMs consistently drag their feet and then half-butt them).
AMD could be cleaning up in workstations with Threadripper, but they don't even have a single OEM actually making such a thing (think one of the gaming focused brands might have one they claim is a workstation, but I doubt it has ECC and lots of other aspects that companies rely on OEMs to provide).
Its one of the reasons I wish AMD would make a high end unified platform. I really don't think most companies are doing much add in cards (they might upgrade GPU, but I'm not even sure they do that versus just upgrading the whole system; and fewer still use any other expansion cards). Which AMD would just need to make the platform and then let OEMs handle the support (which is where most of the money in that market is I believe anyway). They can sell it both in the gaming market and pro markets, where it'd be good for both, while reducing the cost for OEMs (as well as reducing their ability to pull shenanigans and cheap out in stupid ways). AMD should be able to make just as much if not more money from doing that as they do normal sales, plus it'd make for an overall better product for the end users, which will bolster AMD as a brand. Plus it'd give developers target platforms which should make support better (both easier, as well as longer term it means less variables for them to have to consider).
