Desktop Kaveri family adds new models, Pro variants


— 10:35 AM on June 9, 2014

AMD introduced a new family of mobile Kaveri APUs last week. Around the same time, the firm quietly updated its lineup of desktop APUs based on the same silicon. A couple of new models were added to the standard desktop family, and there's a whole new collection of Pro-series chips. Here's how the desktop additions stack up against the three Kaveri variants launched earlier this year.

A10-7850K 2/4 3.7GHz 4.0GHz 8 720MHz 4MB 2133MHz 95W
A10-7800 2/4 3.5GHz 3.9GHz 8 720MHz 4MB 2133MHz 65/45W
A10-7700K 2/4 3.4GHz 3.8GHz 6 720MHz 4MB 2133MHz 95W
A8-7600 2/4 3.1GHz 3.8GHz 6 720MHz 4MB 2133MHz 65/45W
A4-7400K 1/2 3.5GHz 3.9GHz 4 756MHz 1MB 1866MHz 65/45W

The A10-7800 slots in just below the top-of-the-line 7850K. Its CPU clock speeds are a little bit lower, and its multipliers are locked, but the chip has a lower TDP that can be set at 65 or 45W.

Cutting the TDP should reduce the core and Turbo frequencies; the A8-7600 we tested earlier this year runs at 3.3/3.8GHz in 65W mode and 3.1/3.3GHz in 45W mode. Unfortunately, AMD's official specifications page doesn't list separate frequency ranges for the APUs with configurable TDPs. Based on the information displayed on the A8-7600, it looks like the published specs reflect the base clock in 45W mode and the Turbo speed in 65W mode.

The only other addition to the standard desktop family is the A4-7400K, which has fewer CPU and GPU cores, less L2 cache, and a lower maximum memory speed than its peers. AMD hasn't listed the prices for the new APUs, but I'd expect the A4 to be especially cheap.

And now, the "professional" family:

A10 Pro-7850B 2/4 3.7GHz 4.0GHz 8 720MHz 4MB 2133MHz 95W
A10 Pro-7800B 2/4 3.5GHz 3.9GHz 8 720MHz 4MB 2133MHz 65/35W
A8 Pro-7600B 2/4 3.1GHz 3.8GHz 6 720MHz 4MB 2133MHz 65/35W
A8 Pro-7400B 1/2 3.5GHz 3.9GHz 4 756MHz 1MB 1866MHz 65/35W

These APUs are largely identical to the other desktop offerings. The ones with configurable TDPs scale all the way down to 35W, though, and the specs suggest the 10W decrease doesn't impact frequencies.

We haven't heard much about what these new Pro-series APUs entail, but the official product page suggests they have more extensive management features and longer product life cycles. Graphics drivers certified for professional-grade rendering applications aren't part of the package—at least not yet. Thanks to CPU-World for the tip.
