Using Google translate the one line i notice most is this "125 watts running at 3GHz + with 8-core"

So if it were 50% faster core for core than previous 3ghz cpu's that would very much impress me as long it did not cost an arm and a leg.
i personally dont think it will cost as much as the i7 980X more like i7 950 price range. the mobos are gonna cost an arm and a leg

On the other hand, we have yet to see how Intel's LGA2011 chips performs.
All I will say on this matter is that they're pretty damned fast :pimp:

This really depends on what they call a core:
1. A real core.
2. One half of their SMT arrangement.

In the case of 1, I agree. In the case of 2, their octa-core processor is not a "true" octa-core. According to what I know about bulldozer every pair of cores is a hybrid between Intel's SMT approach (HyperThreading) and a true pair of separate cores. It is getting hard to define this architecture by the number of cores in the way previous generations could be, but on strict terms, this is a 4-core processor with AMD's flavor of SMT.

In case 1, we're talking about nothing special. In the case of 2, we're talking about some serious processing power.
No it is an octa core - every core in the module has a dedicated SP but they share a "fat" FP which can either do 1 FP calc for each or an advanced 256-bit calc (which we probably won't se for a while because nobody will have ready code...)

AMD tends to offer lower prices on their chipsets than Intel.
So in the end AMD boards are still likely be significantly cheaper than Intel boards.

Not quite. There are additional things there which are shared, such as instruction decoders. Again, at least as far as I know. These are closer to real cores than Intel's HyperThreading, but they're not quite separate cores.

stop doing that you're getting all of our hopes up :( . How likely is it that they deliver a Quad Core that is 50% faster than the 950? When was a new cpu generation _ever_ 50% faster than the previous one clock per clock? The only thing that comes to mind is conroe compared to NetBurst :/

I hope this is true,will be nice to have some real competition with Intel for a change..But we all know hype when we see it...:)

well, if AMD's 1 and half year late 32nm Bulldozer 4 module 8 core processor beats a 2008 core i7 4 core 8 thread processor, we've really got a lot to cheer about.

I think it's more likely to be scenario 2 as I remember an article on anandtech midway through last year, that stated each core is one half of a bulldozer module. What we really need is for JF-AMD to clarify the module versus core thing

50%.....yeah in what, a Cinebench R10 Multi-Threaded benchmark maybe. But still, as anyone would want, I'm hoping it will bring some tough competition to the market.

I am pretty sure these numbers have never lied
Anyway, taking the phenom and core i7 as references is not the same thing and bulldozer should end up 20-30% faster than i7 processors. The 8-core does not mean anything against a 6-core from intel. The only thing that is needed is the performance.

When overclocked the i5 2600k can beat the i7 980x in some cases, what will the hyper threaded 6/8 core sandy bridge i7's do?

To be honest this release is far from specific enough, 50% core for core would be amazing but I'm doubting that, an 8 core CPU that's 50% faster than a 6 core CPU does not exactly sound amazing unless the 8 core is clocked much lower but no details.

I want to be impressed but until i see something more specific it's hard to be :(
You can't throw overclocking into the equation vs non-oc'd chips. Theres lots of upsets when you do that. Got to be oc vs oc. We all know it's possible to take something cheaper and weaker, then oc it to beat something faster and more expensive, thats why we oc.

As much as I love AMD, because of pricing, I must say that even if this is true AMD is a year late with bulldozer... This time, next year Intel will have 22nm CPU, and AMD, probably, a year behind Intel, again... Good thing is that we will se some good bang for our buck...

Uh..What? The CPU' are rumored to come out the 2nd and 3rd quarter of this year. If it's 50% it'll be faster/equivalent (apparently) than the the newer Intel CPU'. Can't recall if server or client products arrive first.

edit: I kinda misread what you posted originally.

50% faster than both the i7 950 and P2 X6 1100T is a bit too open ended.

For a start the i7 950 is already faster than the 1100T in all but the most heavily thread situations so 50% faster number starts to lose its meaning.

My assumption is that these new AMD chips will fall in line with the performance of the current Sandybridge range (excellent) and will compete accordingly on price.

Intel will still hold the CPU performance crown with the LGA2011 chips.

Very true but i just meant as in the i5 sandy bridge cpu's are close enough to the 980x that a speed bump lets them compete so what do people think will happen with the sandy bridge i7's come out.

If there is a dual threaded 8 core sandy bridge CPU (I'm unsure what will be available 6 or 8?) i would expect bulldozer to be left in it's dust... although knowing Intel they will cost way too much for me so i will probably end up buying a bulldozer core anyway :laugh:

Wikipedia said:
Two tightly coupled, "conventional" x86 out-of-order processing engines which AMD internally named module
(Single-Module ==> Dual-Core, Dual-Module ==> Quad-Core, Quad-Module ==> Octa-Core etc...) Bulldozer family will lay emphasis on multithreading and multiple cores too

Two dedicated integer cores
Wheres your need for clarification? 4 modules = 8 cores, 8 modules = 16 cores and so on.

This is a Octo-Core we're talking about or are you immplying that they used a 16 Core wich would make the 50 % statement much less impressive :/

the way i see it, is thus.

33% more cores (6 to 8 for the AMD comparison) + 17% faster per clock = 50% faster (in 8 threaded synthetic apps/encoding programs etc)

You guys are also forgetting there is supposed to be a 12 core Bulldozer as well.
that one should well crap over a 50% boost.


doubling the cores should make it 100% faster, and then some (based on IPC improvements)
