According to most watched streams on twitch.tv and to Steam statistics the most played games in the world are League of Legends, DOTA2, CS:GO, Hearthstone, TF2 or the FM series. Last year in US universities, all I see in dorms is students playing LoL / DOTA2. Well, it turns out that AMD's APUs are the perfect fit for these type of games while Intel's APUs are too weak on the GPU side.
Unfortunately many hardware review sites are having a hard time keeping up with the changing taste of today's gamers. They cater to the more upscale gamers who -can- and are willing to spend hundreds of dollars for their computers. There is an unintentional bias when they review APUs like Kaveri. To test the iGPU they used games like Bioshock Infinite, Metro Last Light, Tomb Raider or even Battlefield 4. It makes Kaveri looks really bad even though a gamer who is considering to buy Kaveri wont be able to afford those newer AAA titles anyways .
What they should have done instead is to test whether you can play Dota2, LoL, CS:GO on an acceptable fps. Games that people actually played, are playing and will be played for years to come. Moreover most gamers who play competitive online games dont care much about AA or being able to have maxed out quality. APUs give you the required fps without having to deal with the cost, the form factor, the hassle of installing, the noise and the heat of discrete GPU.
Dota 2 and Lol play fine on any recent integrated system.
This card is not faster than the 512 Core + 2133/2400MHz dual channel Kaveri. Also, the card is only 1GB when Kaveri can been setup with up to 2GB iGPU ram.
If you buy a Core i3 + this card you get at best the same performance as A10-7850K with 2133/2400MHz but with an extra cost, noise, heat etc. Also to note that this setup doesnt support Freesync and Mantle, both are available to Kaveri APUs.
edit: I dont even believe that the Core i3 + 730 1GB DDR5 (64bit memory) will be better than the much cheaper A10-7800 2x 2133MHz.
384 kepler cores + 40 GB/sec is easily faster than kaveri.

A10-7850k only adds about 10% onto the 6800k. Never really catches the 640, let alone the 640 with more bandwidth.
