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 Keeps Q1 Interesting
CES 2016 was not a watershed moment for AMD. They showed off their line of current video cards and, perhaps more importantly, showed off working Polaris silicon, which will be their workhorse for 2016 in the graphics department. They did not show off Zen, a next generation APU, or any AM4 motherboards. The CPU and APU world was not presented in a way that was revolutionary. What they did show off, however, hinted at the things to come to help keep AMD relevant in the desktop space.
It was odd to see an announcement about the stock cooler that AMD was introducing, but when we learned more about it, the more important it was for AMD’s reputation moving forward. The Wraith cooler is a new unit to help control the noise and temperatures of the latest AMD CPUs and select APUs. This is a fairly beefy unit with a large, slow moving fan that produces very little noise. This is a big change from the variable speed fans on previous coolers that could get rather noisy and leave temperatures that were higher in range than are comfortable. There has been some derision aimed at AMD for providing “just a cooler” for their top end products, but it is a push that is making them more user and enthusiast friendly without breaking the bank.
Socket AM3+ is not dead yet. Though we have been commenting on the health of the platform for some time, AMD and its partners work to improve and iterate upon these products to include technologies such as USB 3.1 and M.2 support. While these chipsets are limited to PCI-E 2.0 speeds, the four lanes available to most M.2 controllers allows these boards to provide enough bandwidth to fully utilize the latest NVMe based M.2 drives available. We likely will not see a faster refresh on AM3+, but we will see new SKUs utilizing the Wraith cooler as well as a price break for the processors that exist in this socket.
