Computex 2018: AMD TR 32 core CPU , Intel 28 core 5ghz CPU announced

https://www.anandtech.com/show/12906...w-x399-refresh

https://www.anandtech.com/show/12907...u-need-to-know

Looks like Intel lost the core advantage for their x299 platform, but they used some kind of phase change water cooling for it. I imagine it requires a lot of power and cooling to keep 5ghz.

AMD on the other hand looks like they finally got rid of the dummy dies and went nearly full Epyc, besides the PCIE lanes and memory channels. The slide mentions it has the Zen+ improvements which include XFR2 and Precision Boost 2, both have which increased single core performance for Ryzen quite a bit. Works on existing socket.

Only issue still is preventing programs and threads from crossing the glue too much.

Also there is currently a debate whether or not the Intel 28 core 5ghz is even feasible, there is a good chance they caught wind of the 32 core TR shortly beforehand and panic pushed a demo rig together with hidden chillers just to take some of the hype away from AMD.

Will there be a product to ship?

Gamer Nexus nicely summed up this fake 5GHz on all 28 cores

The Anand article is honestly more informative, despite being rushed to production. And it's not fake, it's just a total custom jobbo (even the motherboard!) with unobtanium, to the point that they were able to choose the top five overclockable cpus off the factory line, pair them with a custom mobo and a top-end watercooler.... and still only one could hit it. That really said it all. They say a lot of vague things, hope everyone salivates and builds the product up in their head.

It is an exciting demonstration of the limits of technology, if nothing else.

I just hope nobody actually thinks they'll be able to buy this, save for mortgaging their house to buy this specific box.

Cinebench (SSE2) test runs on that machine only for few seconds so maintaining 5GHz during that period wasn't that difficult. CPU basically didn't have enough time to warm up
I bet that 28 core @ 5GHz would not survive few hours of encoding in x265 (4k + preset veryslow + AVX2). That 5GHz would most likely drop to base level in couple of minutes
Whole system could even crash with forced AVX-512. Yes. So for me 5GHz on that CPU is fake. Extremely desperate move in reaction to Threadripper 32core.

This is by far the most explanatory video of what really happened during that "28core 5.0GHz" demo.

If posts could be stickied, this would be it.
