Today, Intel launched 50W low power versions of the 45nm Quad-Core Xeon processors (the L5400 series).
The 2 new SKUs are listed below:

Quad-Core Xeon L5420 2.50 GHz, 12MB L2, 1333MHz
Quad-Core Xeon L5410 2.33 GHz, 12MB L2, 1333MHz

These products offer IT and business users 2 primary benefits:

  • 45nm 50W quad-core brings 25% improved performance over previous generation 65nm 50W quad-core processors
  • They also run 30W cooler than mainstream 80W quad-core processors delivering the same performance at the same frequency.

We have seen strong interest for these 50W quad-core products and I'd like to hear from you on where you would use low power quad-core and why?

They are perfect for blade server applications. As I'm sure you know it's challenging to cool a fully loaded blade chassis and the lower power quad-cores helps.

"Green IT" is the buzzword of the moment. For our new servers I could justify a 50W CPU with lower clock speed more easily than an 80W CPU with higher clock, even if the former cost more.
Not that I want to give Intel ideas. The board of directors doesn't understand "clock speeds" but they understand less power usage and looking good in the eyes of the media when "doing something" about climate change.

Agree - I am seeing blades and other dense rack (1u) users adopt these low power processors. Is your end goal filling the blade chassis (ie maximize footprint use) or reduced power consumption (electrical and cooling costs)?

Green certainly seems to be the new gold ... I can't go anywhere without hearing the buzz. Will be interesting to see this ramp up even more as we approach Earth Day next week. Do you think this focus on green is good for IT? What is the right balance between performance and power?
