Justin Rattner kicked off Intel's Spring Developer Forum with a talk about Energy Efficiency, inevitably involving a discussion about Conroe, Merom and Woodcrest.

This slide below is particularly interesting as it is the first time Intel has actually disclosed this sort of information. The chart plots the amount of energy required to execute a single instruction as a function of processor performance. Obviously, the higher the performance, the lower the efficiency.

The next version of the slide includes the work from the Israel Design Center, more specifically the Pentium M and Core Duo.

The Pentium M was actually able to match the energy efficiency of the original Pentium processor. Succeeding generations of the Pentium M continued the trend, offering energy efficiency of the original Pentium while offering performance competitive with the Pentium 4 processor.

    So, Conroe won't be that cool running then. Not exactly shocking, though. A 40% reduction on power consumption versus the P-D 950 makes Controe land at like 70-75W, correct? I guess it's quite impressive if the performance claims hold true.

    65/80/95W - desktop, server, XE.

    FYI - Most of the images are showing up as red x's here. Not sure if the server is getting hammered or if they're just broken though.

    Looks like the Conroe should be quite more powerful (according to Intel) than their current top of the line. I wonder what this will do to the AMD v. Intel debate... I suppose just up the ante

    Also, the single cycle execusion of the SSE extensions should really increase the benefits gained from SSE applications. This will do wonders for video encoding.
