Lower Power, Same Performance
AMD is in a strange position in that there is a lot of excitement about their upcoming Zen architecture, but we are still many months away from that introduction. AMD obviously needs to keep the dollars flowing in, and part of that means that we get refreshes now and then of current products. The “Kaveri” products that have been powering the latest APUs from AMD have received one of those refreshes. AMD has done some redesigning of the chip and tweaked the process technology used to manufacture them. The resulting product is the “Godavari” refresh that offers slightly higher clockspeeds as well as better overall power efficiency as compared to the previous “Kaveri” products.
One of the first refreshes was the A8-7670K that hit the ground in November of 2015. This is a slightly cut down part that features 6 GPU compute units vs. the 8 that a fully enabled Godavari chip has. This continues to be a FM2+ based chip with a 95 watt TDP. The clockspeed of this part goes from 3.6 GHz to 3.9 GHz. The GPU portion runs at the same 757 MHz that the original A10-7850K ran at. It is interesting to note that it is still a 95 watt TDP part with essentially the same clockspeeds as the 7850K, but with two fewer GPU compute units.
The other product being covered here is a bit more interesting. The A10-7860K looks to be a larger improvement from the previous 7850K in terms of power and performance. It shares the same CPU clockspeed range as the 7850K (3.6 GHz to 3.9 GHz), but improves upon the GPU clockspeed by hitting around 800 MHz. At first this seems underwhelming until we realize that AMD has lowered the TDP from 95 watts down to 65 watts. Less power consumed and less heat produced for the same performance from the CPU side and improved performance from the GPU seems like a nice advance.
AMD continues to utilize GLOBALFOUNDRIES 28 nm Bulk/HKMG process for their latest APUs and will continue to do so until Zen is released late this year. This is not the same 28 nm process that we were introduced to over four years ago. Over that time improvements have been made to improve yields and bins, as well as optimize power and clockspeed. GF also can adjust the process on a per batch basis to improve certain aspects of a design (higher speed, more leakage, lower power, etc.). They cannot produce miracles though. Do not expect 22 nm FinFET performance or density with these latest AMD products. Those kinds of improvements will show up with Samsung/GF’s 14nm LPP and TSMC’s 16nm FF+ lines. While AMD will be introducing GPUs on 14nm LPP this summer, the Zen launch in late 2016 will be the first AMD CPU to utilize that advanced process.

AMD's Godavari architecture is the last one based on Bulldozer, which will hold the company's product stack over until their Zen architecture arrives in 2016. The A10-7870K was added a month ago, with a 95W TDP at a MSRP of $137 USD. This involved a slight performance bump of +200 MHz at its base frequency, but a +100 MHz higher Turbo than its predecessor when under high load. More interesting, it does this at the same TDP and the same basic architecture.
Remember that these are AMD's benchmarks.
The refresh has been expanded to include the A8-7670K. Some sites have reported that this uses the Excavator architecture as seen in Carrizo, but this is not the case. It is based on Steamroller. This product has a base clock of 3.6 GHz with a Turbo of up to 3.9 GHz. This is a +300 MHz Base and +100 MHz Turbo increase over the previous A8-7650K. Again, this is with the same architecture and TDP. The GPU even received a bit of a bump, too. It is now clocked at 757 MHz versus the previous generation's 720 MHz with all else equal, as far as I can tell. This should lead to a 5.1% increase in GPU compute throughput.
The A8-7670K just recently launched for an MSRP of $117.99. This 20$ saving should place it in a nice position below the A10-7870K for mainstream users.
