Not bad. 30%. Bet when drivers and programs (server) get optimized we should see more like a 50% performance boost.

Wonder if any is IPC or if its all due to the cores itself.

They should have bought it out when i7 came out to compete with. Bringing it out a year later is a little pointless but hey, you can't win em all.

I think AMD had to wait for a smaller procss node just like how Intels 6 core will be 32nm as well.

If they can push the IPC then its fine. But in the market its in it will have stiff competition from Core i7/i9 sinc i9 will be a LGA1366 drop in.

This is istanbul, it's been out for a few months now already. Are you confusing it with Thuban, the 6-core desktop?

+1 to jennyh

Commercial/desktop 6-cores is called Thuban. Istanbul is for the server segment.

And what would the difference be, well besides socket maybe. Other than that its the same exact CPU core just like how Xeon is the same as Core i7.

thuban is a revised istanbul with lower thermals and ddr3 support, thats y its not out yet.

Potentially very different cache look-ups. Also, doesn't Istanbul have another Hypertransport ring for socket to socket communications?


(or is that for quad socket procs only...)

Isn't the Thuban called "Bulldozer" too?

bulldozer is next gen arch, thuban is current arch, just 2 more cores

Not sure. I would think for quad socket servers yes. But for dual it wont make a difference.

Thuban is a modified version of Istanbul for the desktop AM3 socket rumored to be called Phenom II X6, it's still a K10 45nm part. Bulldozer is an all new architecture which will be built using 32nm.
