W Series Intel CPU in new MP

[ggg05a]

Does anyone have a clue as to why Apple did not offer the W series Nehelam processors in their current flavor of the MP? They are 130w v 95w of the E series (2.93GHz).

I was thinking it could have been a heat issue . . . any other ideas?

The 4 core single processors ARE the W series.

The W3520 and W3540 are in the quad core MPs. The 3500 series Xeons are meant for single processors setups. As far as the W5580...who knows? Too expensive maybe.

Ahh I see. Single core MP have the same HS/F as the dual cores?

If you mean "heatsink/fan"... then yes and no. The quads have a bigger heat sink because there is more space, but they have a fan just like the octos. And there is no dual core, only quad or octo.

I don't think the W5580 is out yet. When it is, Apple may offer it as an option.

Just curious: why would Apple want to use a chip that uses more power (130W) rather than less (95W)? Isn't having the current Xeon that runs at 95W a good thing, rather than 130?

1) They are cheaper
2) More importantly, the 3500 series are the only Xeons made for single processor setups

And I doubt Apple cares much about TDP on Mac Pros.
