Zambezi lineup slide shows up

Written by Slobodan Simic
amd

125W for the top one

The guys from Ati-Forum.de have managed to get their hands on an AMD's Zambezi slide which shows some info regarding AMD's new lineup that should start to show up sometime in the second quarter of 2011.

The lineup includes a total of four Zambezi CPUs, two 8-cores, one 6-core and one 4-core, all with Turbo Boost. The two 8-cores share the same amount of L3 cache, 8MB, and should be the first ones that will appear during the first half of the 2Q 2011. The top one will have a 125W TDP while the second will have a 95W TDP and it will probably be somewhat slower.

The 6- and 4-core parts should show up in the second half of Q2 2011, and both will have a 95W TDP. The 6-core will have a same amount of L3 cache as the 8-core models while the 4-core will have half of that, 4MB. Of course, it is still early to talk about the precise date and things might change while we get closer to Q2 2011, but for now AMD's roadmap looks like that.

You can find the slide here.

Being 32nm parts with 125W for the top one, they must be bombs!

Bring them on!
I hope Bulldozer is going to give some much needed competion at the high-end.
My only fear is that it was meant to come out 2 years ago. Does that mean it's 2 years worth of performance out of date? Lets hope not.
Sandy Bridge is looking pretty good, if you buy the 'k' version, and things will only get better when they finally bless us with the high-end LGA2011.
The inovative design of Bulldozer should mean at the very least AMD will again be able to win sales again on price to performance as the die space for its '8 core' is much reduced than a normal 8 core design and for the time being atleast both parties will be using 32nm but supposidly Intel will have 22nm ready for 2H 2011 but what it brings to market, if anything, remains to be seen.

Surprising things on that page: Bulldozer/Zambezi has only 1 MB L3 cache per core? Is the 6 core part a crippled 8 core, since it has the same amount of L3?

We also see that quad-core Llano will have a 100W TDP and that there will be a crippled 3-core Llano.

I wonder if these new AMD processors will support triple channel memory or something higher since it will be an 8-core.

They will "only" support Dual-Channel, but the speed at 1866MHz makes up for that :)

All i have to say about the Zambezi series chips is that they are kinda late for me, i would have loved to see the architecture on 45nm, even if that would have meant a watered down implementation of the arhitecture.

Oh one more thing, am i the only one who thinks the cache is rather small? With 8 cores and just 8 Mb of L3 i doubt they will be kings of performance. Atleast i hope they will be priced fair, afterall that's the only thing that AMD can do, lower their magirns.

16MB of L3 Cache for Orochi Bulldozer but I am a bit confused about Zambezi here. I'm sure AMD has something up their sleeve here.

t looks like AMD is behind technology when it comes to there processors. I will stick with the intel 6-core or wait on the new intel lga 2011 socket to come out. I've been waiting a whole year o build my computer and amd has yet to surprise me what should I do people. I already bought the i7-930.

Way you are so smart-ass, it is tested and confirmed that differences between an 4 core processor with 4 to 6 MB L3 cache is from 1 to 3 %!!!

You're not being specific.If the "test" application is coded to take advantage of muticores CPUs, then a slow clock per clock 8 core cpu will outpace a faster clock per clock 4 cores CPU in that particular test.
But my point wasn't related to the number of cores, rather i was stressing the fact that a 8 core CPU is a high end part but in this case it only has 8 mb of L3 cache which is kinda small when you compare it to present and past CPUs (Penryns had like 12 mb L2?).
I have no performance feagures at the moment, thus i remain hopefull untill i see the reviews but i do dislike some design choices.
