This is a pretty bold change and really makes Intel chips less appealing. With the recent kernel changes for Intel's Spectre issues and this chip coming up, I think it's a distinct possibility that AMD will take back a ton of marketshare in the server space. If these chips really do have a ~25% performance gain over Ryzen (not counting IPC gains), I might just upgrade, and I think a lot of other people are in the sam…

What's disappointing is that none of the major cloud vendors has made any real commitments to AMD, at least none that I've seen.

If speculative execution is a problem and you need to give each VM its own exclusive cores, great when you can source parts with 64+ cores on them!

Last I saw MS SQL licensing among others like it have a pricing structure per CPU core... That’s going to need to be modified I think!

Oracle says "Haha, no."

Oracle says "Looks like our profits will double each time AMD doubles the core count of their flagship chip."

Do the new 8th gen Intel chips finally deal with Spectre/Meltdown issues in hardware or do they still depend on OS level fixes?

Larry Ellison needs a bigger yacht, time to re-up your Oracle per core licensing agreement.

64 cores with 128 threads. Hope that comes to threadripper. I love and for bringing back competition to the CPU market. We've bought a ton of amd machines in the last year, great bargains in our space.

Benchmarks on the 32-core TR are... disappointing, to say the least.[1] If you’re purely compute bound, it can be a win over the 16-core version, but if memory access is a factor, it’s a wash due to the extra hops to memory. And to my mind, there are very few pure-compute applications that wouldn’t benefit more from AVX2 and the like... in which case a cheaper Intel CPU would still wipe the floor with the 32-core chi…

The neutering isn't that bad, you can still get an improvement by adding more cores. Here's some of my results on a task doing a lot of string comparisons (plus some other stuff): https://image.ibb.co/ecH9VL/coretest.png

Predicted = Theoretical improvement (2 cores are 2x faster than 1, etc)

10k/00k = number of entries being searched (there's actually a variable number of strings per entry)

I hope AMD has something on their video chip line-up against nVidia as well. I'm curious if they knew nVidia was working on ray-tracing and plan to implement the same API or if they have some other tech they have up their sleeve they've been working on vendors with. I hate how nVidia has such a monopoly on the video chip market. Who knows, maybe Intel will finally get back into the gamer 3D market and we might finally have three options again.

AWS began releasing a new AMD generation a few weeks ago.. https://aws.amazon.com/blogs/aws/new-lower-cost-amd-powered-...
