post #41 of 61
I'm waiting till it goes to 22nm, then I will get one.
It's TURBO TIME!

AMD's best fighting chance is in multithreading were they can chunk many small cores to handle tasks. Intel is just too far ahead in terms of single thread clock performance.



This is the first time I've heard of Socket 1356... From what I heard, there is a socket 15xx and 2011 both of which are supposed to replace 1366. I'm not sure which to believe at this point.
i smell an Intel fanboy. AMD bulldozer will be 12 cores with 2 threads per core IIRC. How is that slower than a 2 core processor. PROVE IT

Err, in a single-threaded app?? Still plenty of them about....

Yep, me too, if it can demonstrate superior performance at the time. I won't be upgrading my rig for at least 2 years, so I suspect 22nm is where the world will be at. That said, I might give the whole of Sandy Bridge a miss and aim for Haswell (presuming I don't jump to AMD, only time will tell!)

bulldozer(the architecture) will be implemented as zambezi(the processor codename) on desktop with 8 cores, 1 thread per core.

interlagos(another processor codename) is the top-end server part, with 16 cores, 1 thread per core.

first BD iteration will not have any form of hypethreading.

Looka good but not as good as some other sockets ou there.

I wonder about this, because of this line in the wiki article:

Quote:
The design of Bulldozer is heavily revamped from the previous generation. With Bulldozer, the two 128-bit FMA-capable FPUs can be combined into one 256-bit FPU. This design is accompanied with two integer cores each with 4 pipelines (the fetch/decode stage is shared)
I thought having greater than 1 pipeline per 'integer core' (or ALU, as I presume they mean) indicated hyperthreading?

Bulldozer also looks like it will be a four issue core, and unless they do something horribly wrong, it should be noticeably faster clock for clock, core for core, than Phenom II.
Thuban matches Core i7 clock for clock, Bulldozer will (I'm guessing) at least match Sandy Bridge.

Conroe > Penryn, Nehalem > Westmere, Sandy Bridge > Ivy Bridge. (I think I've got those right?)

The Q9550 is a tweaked, 45nm version of the Q6600...

Except we don't know if the single threaded performance is worse than Intels, especially with Intel sacrificing some single threaded performance in favor of Multi core with Core i7. (When you're only using 4 cores, HT off improves performance a little)

No, you wont be able to upgrade to the new cpus unless you get yet another motherboard

execution pipeline != hypethreading

hypethreading is done by duplicating the architectural state registers.

can someone here in OCN point out to me what architectural innovation Sandy Bridge copied this time from Barcelona?

winner gets a cookie.
