預計會同SB freq差唔多

It looks around 15-20% improvement for the same frequency from SB.

INT or FP or SIMD or AVX?

I am not sure, just a rumor from the web and a guess based on the bench.

等出左先算...

Somewhat I want to predict how much I will lose for buying a Sandy in Sep, and if it is worthwhile to further suspend the plan, through quite impossible.

it depends on usage

if you need multi-thread performance, SB-E, BD, will be better than IVB

Yes, but another question is I want to utilize ECC memory at the same time, I am not sure if SB-EP is still that avoidable to me.
And I am not sure about building an Opteron system, I cannot see a s ...

Socket G34 is for 2-4 socket systems

It looks the upcoming bulldozer Opteron uses only Socket G34,
so it maybe hard to take BD as a choice.

C32 also, but nearly the same infrastructure with Socket AM3+
And C32 is optimized for performance/power but not max performance

Thanks for telling, I may take a look on the feasibility on building with those parts later.

If you want a workstation, SB-E is your only choice

Not really a workstation, but a stable machine with satisfactory performance lasting for around 4 years within budget.
Therefore Xeon E3 should be a right choice for me, I simply thinking that if the ...

then you don't need ecc

You are correct with this,
I don't really need ECC but in case it is within budget, it is preferred.
I can accept the performance of SB Xeon and think that it would serve me well in a few years, so y ...

SB-E will be of ~3GHz range with 6c12t

That would no doubt be bringing a performance boost with 2C4T more, and also the quad channel memory will favor the editing in Photoshop, that is quite critical to me.
But the point is still on the b ...

ECC is useless for your intended usage...

我諗主要係support DX11多過真係效能上升...
實際效能在無乜其他特別增強, 好難真係快60%

不過+60%同Trinity claim既+50%, 其實又差唔多
即係距離其實無縮少到

intel SB報流料

咩流料?

發佈果陣一路都話係995M transistor (4-core version)
而家有人追問IVB transistor count

一口氣將SB個transistor count推上1140M
咁佢同BD個competitive advantage無左一大半

Maybe the advantage of Tri-Gate should be taken into account; the advancement may cover the loss due to the transistor number boost.

咁做咩要出假SB transistor count
