The AMD A10-7800 is a locked Kaveri quad core with (with 8x GPU core) base clocked at 3.5GHz with turbo up to 3.9GHz. If you need an unlocked processor, there’s the 3.4GHz variant 7700K and the 7850K which is clocked at 3.7GHz. The TDP is of 65w. This APU was out at the end of July, but we got the processor about 2-3 months ago. It couldn’t have come at the better time to be honest. In one corner, we have this APU and then there are processors from Intel stable- G3258 and the i7 4790K. Kaveri Vs. Haswell-refresh.

Okay, so comparing it with i7-4790K might not make sense for a  lot of people. But it helps to see how this accelerated processing unit (as AMD calls it) stands as it retails for $141.99. But then there’s the G3258– Intel’s 20th anniversary Pentium ‘love bug’ that is priced for $70- half of AMD A10 7800.

While Richland was based on 2-4 Piledriver architecture based core, Kaveri is based on Steamroller. It does support HSA features and AMD True Audio.

At the end of this review, most people’s point of view will be pretty much the same like previous AMD APU. But in some comparisons against its previous gen Richland core based A10-6800K, the green CPU/Red GPU team has some good work with it. This APU is based on 28nm fabrication process and uses FM2+ socket.

The newer Kaveri chips are as follows:

Model A10-7850K A10-7800 A10-7700K A8-7600 A6-7400K
Radeon  Radeon™ R7 graphics Radeon™ R5 graphics
Compute Cores 12

L2 Cache 4 MB 1 MB
DDR3 Speed 2133 1866
Display  HDMI 1.4a, Display Port 1.2, DVI

The 7600-7850K chips are Quad-core processors, whereas 78xx have 8x R7 series GPU cores. A6-7400K is the dual-core wielder, with 4x R5 series on-chip GPU. The upper Kaveri APUs are compatible with up to 2133MHz DDR3. What’s interesting is that some of these chips have variable TDP, depending on the clock speed (with and without Turbo) it runs at the time.

Like all paper specs, it sounds good but only when it’s put through its pace we would know how good or bad it is.
