Sandy Bridge GPU gets disabled with discrete GPU

Written by Fuad Abazovic


One or the other
We’ve learned one more about Intel’s Sandy Bridge CPU and its more interesting graphics part. Sandy Bridge graphics support dual displays, but once you plug in a discrete graphics card in PCIe slot, the Sandy Bridge magic will simply shut down.

At this time, we are not aware of any chance that Intel gets some kind of hybrid mode and use its own Sandy Bridge graphics for non-graphics intensive tasks and then use the discrete graphics for the graphics intensive ones. So, graphics lovers who need more performance than what integrated graphics deliver will be safe, new six series chipsets do have support for external graphics, and some companies might even have dual slots for SLI / Crossfire system.

Gigabyte’s GA P67A-UD7 board will be the one to support both Crossfire and SLI. We wish Intel could come up with hybrid graphics and simply shuts down discrete graphics cards when we don’t need them, Nvidia and AMD already offer such technologies.

I could easily reduce the idle power consumption of my rig by 150w or more if Intel released a hybrid IPG/GPU software program to disable power-hungry discreet GPUs when they are not needed.

The efficiency drawback makes itself particularly known when you have dual AMD Radeon HD 5970s in QuadCrossFireX that aren't really doing anything for the majority of desktop productivity tasks. :sad:

No, I want Larrabee instead of fusion.

"..that then one that you get from integrated graphics"

:D you are a journalist? lmao

Man what a ridiculously laughable way to flush money down the toilet! :-* +58

well I guess we can all say good-bye to Nvidia's Optimus technology. Now they really will have no place in the chipset market soon in laptops/pc

There's no mention what type of SB this will be. It could be only for desktop segment, while the mobile one could come with switchable graphics.

So Sandy Bridge is not DirectX 11 capable and it gets turned off if you get a graphics card. The more I hear about it the less and less impressed I get.

This chip will beat a Bulldozer at gaming, and it wont matter that it has the extra silicon.

With only 4 cores, BD will kill it encoding, and possibly cad - but this chip is going to toast any of the i7 930 series.
