Page 1: Test: AMD A10-7800
Even though we recently heard the first rumors about the successor generation, AMD just refreshed the "Kaveri" series with new models and made final statements about their availability; for a few days, the three new models have been listed on their website. Today we can officially report on the AMD A10-7800, the AMD A8-7600 and the AMD A6-7400K and show you the first benchmarks. In time for the launch, AMD supplied us with a test CPU of the smallest top model. The following pages will provide you with a thorough test of the AMD A10-7800.
It would seem that AMD's "Kaveri" marketing machine will be stoked up for the last time before the start of the "Carrizo" successor. In June 2013 at Computex, the U.S.-based chip manufacturer had presented their new combi processors on "Richland" basis, and only a few hours later they already showed a first model of the "Kaveri" successor at a press conference. However, the "Kaveri" APUs had only been presented officially at the beginning of this year. At the time, AMD had announced three different models in the price range of 120-170 dollars. But for a long time, only the two fastest models had been available. The smallest one, the AMD A8-7600, was meant to be released only at a much later time.
The AMD A10-7800, officially announced last thursday, will be available in stores effective immediately, together with the AMD A8-7600 and the AMD A6-7400K. However, not much has changed when it comes to architecture or features. All models are still being manufactured in the 28nm SHP process at Globalfoundries, their cores are based on the "Steamroller" architecture, and feature a discrete graphics solution based on GCN equipped with up to 512 stream processors.
With "Kaveri", AMD has opted for a slightly revised socket. The three new versions are compatible with FM2+, which in turn is backward-compatible with "Richland" and "Trinity" models.
Whereas the two small versions of the A8 and A6 are meant to complement the lower edge of the "Kaveri" family series in terms of performance and price, the AMD A10-7800 is located only slightly below the flagship. As the name suggests, it does not have an open multiplier, and will thus be harder to overclock. The default clock frequencies have been reduced by 100 in base clock, and by 200 MHz in turbo clock. As for the graphics solution, there are no differences to the A10-7850K. In turn, the maximum power consumption has decreased from formerly 95 to 65 watts TDP. Alternatively, a corresponding motherboard will let you set it to 45 watts, which of course will decrease overall performance a bit. However, AMD states it would sum up to a performance loss of only a few percentage points.
On the following pages we will see how the new AMD A10-7800 is able to compete against the AMD A10-7850K and some CPUs of the "Richland" family.
