CPU vs GPU power usage changes differ between platforms, but they're fairly small. All in all, pretty nice with clearly increased perf.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
