Although the Steamroller cores in AMD's Kaveri-based A8-7600 APU brought a notable boost in CPU efficiency, it felt like the company was mostly focused on gaming performance with last month's update. The A8-7600 wasn't much faster than last year's A10-6800K, but it was quick enough to power modern titles such as BioShock Infinite and Tomb Raider without help from a discrete graphics card.

At the same time that AMD is beginning to deliver on a years-long promise of single-chip PC gaming, its effort toward Crossfiring integrated graphics with discrete graphics is finally maturing. The company first touted 'Dual Graphics' with its first Lynx-based APUs back in 2011, but it was largely dismissed due to Crossfire's poor frame time performance and that remained the case with 2012's Virgo/Trinity APUs.

By the time 2013's Richland APUs landed, AMD was working to improve its frame pacing performance through driver updates and with the arrival of Kaveri, we're starting to see solid Crossfire performance that isn't plagued by frames being dropped and or chopped off. That being the case, we have taken the time to do some dual graphics testing with the A10-7850K, the company's current flagship APU.
