An Introduction To AMD's A78 Chipset
It has been nearly a year since Tom's Hardware last reviewed a motherboard for AMD's processors. And with the recent Godavari APU announcement, we thought we should dust off our Kaveri APUs to see if we can find some additional value in the company's not-so-famous alternative chipsets.
Our own Thomas Soderstrom looked at AMD's A88X chipset from an enthusiast's standpoint and determined that an APU placed into this platform, along with a complementary graphics card, could provide plenty of performance and features to satisfy anyone looking for a mainstream Intel alternative.
But does the average desktop user really need CrossFire, an eight-phase voltage regulator or enough SATA 6Gb/s ports to load an ATX tower? Do they instead want an HTPC with enough bells and whistles for an out-of-the-box overclock, modest graphics horsepower and plenty of room for storage without busting the budget (or form factor)? I have good news, friends: AMD has a solution and you might not have even considered it.

Introducing the A78, AMD's "media-class" chipset. Though it doesn't have any fancy Xes or a three-digit designation, this platform is completely adequate for most folks. In fact, comparing AMD's FM2+-compatible offerings, the only difference between the flagship and A78 is an inability to split 16 lanes of PCIe into two x8 links, two missing SATA 6Gb/s ports and RAID 5 support.
Today, I will be comparing MSI's A78M-E35 and Gigabyte's F2A78M-D3H. I will also be using some of Thomas' data for the Asus A88X-Pro Eric's MSI H81M-E34 results for comparisons to a different AMD chipset and Intel's low- budget offering.
