Having SNAppy Intel 2D Acceleration In 2012
Beginning with the Charts demo inside the new Cairo performance test profile, the SNA acceleration boosts the Cairo rendering performance with Xlib back-end by about 10% for current-generation Sandy Bridge hardware. However, the previous-generation Ironlake (i3 330M) performance regresses compared to the stock UXA acceleration.
For the Cairo gradients test, the SNA back-end was always the winner, but the big winner in particular was the SNA back-end for Sandy Bridge on the mobile Sandy Bridge GT2+ laptop where its performance was boosted by 16%.
The fish demo in Cairo did substantially better with SNA than the stock UXA for both Ironlake and Sandy Bridge. The performance was more than twice as fast with this "experimental" back-end.
The Gears demo was also a huge win for SNA.
