AMD ZEN Engineering Sample Specs Leaked

New details on AMD Zen based CPUs have surfaced, the information is based on engineering samples that AMD already has been circulating. Blogger Dresdenboy AMD has confirmed the information making the reliability of the information plausible.

The engineering samples currently are set at revision A0. The user who spread the details talks about four chips with 4, 8, 24 and 32 of cores. The first two SKUs would be for the AM4-socket, while the last two were intended for servers.

• 4 variants of ES Zen are available at the moment:
• AM4 8 cores with 95W TDP
• AM4 4 cores with 65W TDP
• SP3 24 cores with 150W TDP
• SP3 32 cores with 180W TDP

The two AM4 chips are quad-core and octa-core with 8 and 16 threads. The quad-core would be get 2 MB L2 cache and 8MB L3 cache, while the octa-core would get double that amount. Both engineering samples currently run a clock speed of 2.8 GHz, with a maximum boost up to 3.2 GHz. The TDP of the two would be 65 watts for the chip with four cores and 95 watts for the octa-core. In idle the clock speed can throttle down back to 550 MHz with an amzing power consumption 2.5 and 5 watts idle power.

For servers there is the SP3 platform. The leaker has details on a 24-core and 32-core chip. The boost clock speed is at the 24-core 2.75 GHz and the 32-core 2.9 GHz. The idle-clock rate is 400 MHz here with even lower. The TDP of the two is 150 and 180 watts respectively. These chips have two 64 MB L3 cache, with the 24-core 12 MB of L2 cache and get the 32-core 16MB. This suggests that every Zen-core inherits 512KB of L2 cache, while each set of four cores gets 8MB L3 cache. This corresponds to a previously surfaced die-shot of a core-Zen.

The information has been confirmed by Dresdenboy, he has a good track record, but it remains a rumor/leak and as such a grain of salt is something you should always take this info with.

:)

I'm really hoping the AM4 4 and 8 cores delivers here. Although I bet there is more money to be made from a well working 24 and 32 core set. Is that 95W TDP with or without an iGPU?

I like the sound of that 8/16 on 95W if the IPC is there.

All I hope for is that AMD will come closer to Intel's CPUs this time and offer great price/performance as before.

Heck I don't eve mind AMD to sell their CPUs higher than Intel as long as they'll deliver more performance than Intel's

We really need AMD to come back.

2016Q4 will probably be very crucial for AMD.

They need to succeed both with Vega and with Zen.

Things today doesn't look good though.

Competition is skyrocketed...

:S

@Coseniath: Well AMD can also blame themselves for that... Where are the AIB RX 480 cards? Get them out for god's sake.

@horgen: AMD delayed a lot with AIB RX 480 cards. On the contrary we could find AIB GTX1060 from day1.

AMD did a poor job with reference RX480 aswell.

So... How did they manage to turn a situation where they will play alone in the $250 market to this mess?

This magnitude of fail is fishy. Do they have people inside AMD that will be benefit from AMD going bankrupt?

I hope they success ! if not we are doomed for like more 5 years .... with 1 good company only that make all the prices how they want ....

I don't know. I think some of those who make the decisions in AMD have an extreme faith in the products they make so they do not see the errors they make.

That 95w 8 core looks great. I have a really bogged down 4 core i7 2600k PC i use for brute tasks like video recording and compression and I can see myself replacing it with this at some point.

Unless the price sucks, than i'll likely just get an intel cpu

Much like fanatics of AMD too :D

I hope Zen turns out well. Intel really needs competition. A 5820K (cheapest X99) costs twice what my 920 (cheapest X58) cost 6 years ago when Phenom II x4s were actually competitive.

The 5820K was the last reasonably priced HEDT platform CPU by intel in Norway. With 6800K the price really went up. Sure some of it has to do with our currency not doing so well, but damn, it is a 30%+ price increase.

Where have you been? :O

For the sake of mortal-like prices in CPUs (seriously Intel? $1700 consumer CPU?), we need AMD to succeed.

Actually we demand AMD to succeed! :P

Or they have already made a contract with an insurance company, incase they will go bankrupt, they will get payed...

@Coseniath: Will we see another big lawsuit in the future? :P

@horgen: I honestly don't know, I am just not biting the "oops we made 2-3 mistakes in a row" excuse for multibillion dollar companies... :P

Exactly. Someone has to profit on this :P

Thought I'd bump this instead of opening a new one, so here's some more leakage of engineering sample:

this is the Ashes of Singularity leak:

https://www.guru3d.com/news-story/amd-zen-engineering-sample-shows-promising-perf.html

and this is Guru3d analysis where they downclocked 5960X i7(Intel's 8c/16t) to corresponding 3.2ghz(the zen sample) and ran AOTS with it:

https://www.guru3d.com/news-story/amd-zen-engineering-sample-aos-further-analysis.html

Thoughts?

@howmakewood: I noticed it too, but I have a feeling that AoS isn't the best way to determine how well a CPU could perform in gaming.

That's why I didn't post it. I wanted more benchmarks...

But it might be legit.

We can see around 40% IPC increase from FX8370 (Piledriver) as they promised it will be.

The good thing from previous graphs is that the new Zen CPU is as fast as 3770K (Ivybridge).

The problem is that this is the 8 core 16 thread CPU.

So I will wait for more benchmarks, but single core IPC seems to be way behind Intel... :(

What's interesting is the 6800k isn't really an upgrade. Your max oc on that chip is around 4.3ghz with some very high voltage at 1.3-1.4. The 5820k you can get 4.4ghz with 1.2v and get 4.6ghz on air with a good chip.

I'm happy I saved the $50+ on my 5820k that's running at 4.4ghz with 1.2v over the 6800k.

It's an upgrade if you believe Intel, not the users :P

Broadwell doesn't handle higher clocks well. I think Skylake-E will be an upgrade for HEDT users--- Personally thinking about upgrading to that platform when it releases. When I do I can get rid of older mobos I guess.
