Phenom II X6 1055T or Phenom II X4 965 BE ?

Hi guys,

I'm still deciding which CPU will be part of my new system.
Better a 6 cores with 2,8 GHz but Turbo 3.3 GHz (and 6 MB cache) or a 4 cores 3.4 GHz speed each and same amount of cache?
The latter consumes 125 W and X6 cores 95?

I feel the X4 is more balanced, but still it'd consume a bit more of power being a little slower.
On the contrary the X6 has 6 cores (6 cores!) but 2.8 GHz, still with turbo technology (how many 1,2 or more?) at least 1 core would go to 3.3 GHz...

Please suggest!

Cheers,

I'd take the hexacore. Even in single-threaded stuff it's just about equal to the x4, thanks to the turbo.

It's also a newer part, so might have some new instructions. Not 100% sure about that though.

Thanks, this is what I was thinking about.
Btw, any link to the official spec about this new AMD technology (just to check)?

Even because I don't think I'll use the X4 at 100% 4 cores a lot, plus, even if I'd use this way I guess that:
on same MT process
6x 2.8 > 4x 3.4
But if we're talking about multi process I fear the cache would do it in favour of the X4...

Any other comment/suggestion?

More raw speed is always good for games, when you use gentoo or compile much then more cores are interesting. That's why Intel will sell a i5-680 soon - 3.60 ghz (+turbo 3.83 ghz). Many games do not need more than 2 cores but scale well with higher frequency.

My point is, how many cores out of 6 are able to reach 3.3 GHz?

It will use turbo when 50% of the cores are idle. Basically only the 1090T is interesting but too expensive.

[curaga]

Depends, for a hexa 1090T is still cheap.

I think your the first person that I have heard refer to the 1090T as to expensive. Performance per dollar, it pretty much wipes the board clean.

[Kano]

300 € for the cpu would be at least 50 € too much.

Sorry don't get, why only 1090T would be interesting and not 1055T?
