Lucid's Virtu Enables Simultaneous Integrated/Discrete GPU on Sandy Bridge Platforms

jmke · 1st March 2011, 08:37

Although we came away impressed by Intel's Sandy Bridge CPU and GPU, it was the platform that really let us down. SATA controller errata aside, Intel's 6-series chipset lineup had a huge problem. At launch the P67 was the only chipset that supported CPU overclocking, however P67 doesn't support SNB's on-die GPU. Enter the H67 chipset, which does support processor graphics but it doesn't support overclocking. It gets worse.

One of the biggest features Sandy Bridge has to offer is the support for hardware assisted video transcoding (Quick Sync). In our review we found Intel's Quick Sync to be the absolute best way to transcode video for use on portable devices. There's just one issue: Quick Sync only works when the on-die GPU is active.

If you pair Sandy Bridge with a discrete GPU on the desktop, you lose the ability to use one of the CPU's biggest features.
