[pcgames] Zen engineering samples in the wild. Units up to the 32 core are being tested.

 There are reportedly four different versions of the Zen CPU architecture doing the rounds at the moment, though only two of them are of any real interest to the likes of us. Despite the exciting headline numbers of 24 and 32 cores, two of the chips are full-on server style, only usable in platforms far away from the humble desktop PC.

This might be the shortest ever tapeout-to-board of a new processor class.

"report" says that the ES's are in the range of 2.8 to 3.2 baseclock but that they idle at 550mhz and about 5w or less (4 and 8 core). The larger 24? and 32 core are server socket items.

An 8 core 16 thread at 2.8 base ain't bad in my book.

The most interesting part of the report though stems from the idle performance of the Zen chips. They are reported to idle with a clockspeed of just 550MHz delivering a low power state of 2.5W and 5W for the quad and octo-core CPUs. That’s a seriously low idle power, especially given that AMD’s previous CPU architecture draws some 30W even at idle. The Core i7-6700K looks pretty good at around 3.5W, but Zen’s quad-core chip might even better that.

My llano laptop chip from 2011 idles at 400mhz. I havent measured power usage, and I'm sure it doesn't have the C-State magic that Zen and newer Intel chips do, but it'll idle forever on battery with the screen off.

never heard of the site but their source is Guru3d on a source of a blogger. Still nothing to see here really since we dont know IPC, actual clocks, or well anything for that matter. BUT if AMD can deliver on the 8/16 core/thread CPU with nice IPC and price it will be a rousing success.

God I hope these server chips are great and give Intel a kick in the nuts.

Intel can get away with charging 4000 dollars for their top of line Broadwell-E Xeons (which is the only chip in the new 14nm Xeon line that doesnt have cores disabled) because there is literally zero competition right now.

Broadwell -E desktop is in my opinion just horrible. The 6 and 8 core chips come from a 10 core die, and the 10 core chips come from a 15 core die, and they have the balls to charge 1700+ even though it clocks like garbage and has virtually zero IPC improvement compared to previous generation. To top it off, these are the bad chips they didnt make the grade for the Xeons, so we are getting nothing but leftovers chips. Thats why so many cores are disabled.

Zen being good will be best thing to happen in PC's in last 5+ years. With a 32 core chip priced fairly (2000 or less) intel with lose market share, and that will make me smile. People will support AMD if they have a good product.

A click bait based on a random rumor from a new forum user (at Anandtech). Also the rumor includes at least some of the users own interpretations and expectations.

AMD, I really really really do not care about multiple cores, work on your IPC and then we can talk.

Actual sauce

But wait, here's some bonus sauce from a guest star!

+1.

FX's kick ass till it comes to single core performance. If it was 30-40% higher I wouldn't mind keeping my overclocked 8320. Hyperthreading and other stuff don't matter to regular users as much as better IPC and SC performance.

Then why aren't you using Skylake if single thread is all you care about? Get the fastest clocked Skylake, disable as many cores as you can and clock it to the heavens and enjoy your single core uber clock.

wow, why the hostility lol. AMD needs better IPC to better position themselves on CPU market.
