Thanks for your post however i would like to ask, did you compare these cpu's at factory speed's or did you overclock the A10 just asking and answer would be much appreciated as i will be upgrading to one of these in the future (or at least plan to).
This I3 actually has Hyper threading as well, Also the 6100 was made for DDR4 which doesn't come any slower than 2133 Mhz so I have literally no Idea why DDR3L was used during the test. And regarding the Graphics clock speed while idle it does cap at 350Mhz it does have a turbo clock that boosts it WAY up to 1.05 Ghz. I've used both of these Processors in some of my most recent builds and I honestly think that the 6100 was capable of handling A much wider range of tasks than the 7970. With my I3 running with 16Gb of 2400 Mhz DDR4 memory I have yet to use more than 60% of it's processing capacity With any of my games(No Man's Sky, Warface, Hawken, Rust, Grav) and no more than 80% when Installing all of my essential programs while simultaneously downloading all of the updates. Very rarely do I ever see it being seriously taxed, I couldn't even imagine how the I5 6600 handles things. I paired my 7970K with 16Gb of DDR3 @ 1866 and I will say it does seem to boot quicker than the I3 (by about 20 seconds), More than likely due to it having 4 physical core's but the I3 has 4 logical threads W/Hyperthreading so Post-boot performance doesn't seem to carry over very far for the 7970K. If you dont plan on getting an aftermarket cooler for your CPU though you will appreciate the 7970 more as it comes with an actually really nice stock cooler(REAL COPPER HEAT TUBES!!!), The I3's Stock Cooler was literally the smallest cooler I have ever received from intel with it only being 1.5In thick and overall seemingly insufficent for proper cooling especially once it starts developing dust build-up overtime(It wont take long with small heatsinks). At the end of the day both Processors are very impressive and would be happy with either one but I feel like the I3 has not only has a better value but an exceptional "future-proof" aspect to it that make it my recommendation.
