Intel Xeon E-stepping: 200 MHz more or 30W less

A new stepping has improved Intel's dual socket Xeon 54xx Line, as the top bin has increased from 3.2 GHz to 3.4 GHz (Xeon 5492). Stepping E also decreases power consumption significantly: a Xeon 5482 3.2 GHz which previously came with a 150W TDP now dissipates 120W. Both the Xeon at 3.2 and 3.4 GHz are targeted at the HPC and workstation, and have a 1.6 GHz FSB.
For the servermarket, the Xeon X5470 at 3.3 GHz is launched (120W TDP). The Xeons for the server market continue to use a 1066 MHz FSB.
The most spectacular announcement is the L5430 which needs only 12.5W per core but runs at 2.66 GHz. The pricing of this lower power version is quite competitive and puts even more pressure on AMD. AMD's fastest low power Opteron is still limited to 1.9 GHz. With the current trend towards green IT and blade servers, the importance of the low power CPU market will only increase.

The server CPU's still use 1333Mhz and not 1066 Mhz.. Its says so right there on the slide.. wonder how you missed it..mobilecomputing - Monday, February 9, 2009 - link
Still some very powerful chips. I wonder when netbooks will get that kind of horsepower?mobilecomputing - Monday, February 9, 2009 - link

The L5420 has a 50 watt tdp and runs at 2.5Ghz, so I fail to see what makes the L5430 so spectacular.What I don't quite understand is why the entire Core 2 Duo line is 65 watt or greater, even at 45nm. There are a couple dual core Xeons with a tdp of 40 watts on their 65nm process. I would think that they could do better than 65 watts with the Core 2 Duo E5200 and E7200.

Eventhough the 2.5 GHz at 50W does indeed exist already some time, the fact that Intel has a CPU that is clocked 33% faster than the competition at a slightly lower power level (let us add 10W or so for the memory controller) is quite spectacular. It will be pretty hard for AMD to best that even with 45 nm CPUs.Natfly - Monday, September 15, 2008 - link
I'm not saying the L5430 isn't impressive. The entire 50 watt line is pretty awesome. I'm just saying the L5430 is a marginal improvement on an already existing line, nothing shocking.rbfowler9lfc - Tuesday, September 9, 2008 - link
Er, 166MHz more with the same TDP?
