AMD's string of tablet failures may end with Mullins chip

Agam Shah | April 29, 2014
AMD releases a new tablet chip called Mullins and a laptop chip called Beema, which are based on the Puma+ architecture.

But the market is yet to evolve, and there will be growth in Windows tablets, hybrids and laptops, he said. There are no current plans to bring native Android support to x86 chips like Mullins, Lensing said.

AMD has cranked up clock speeds in Mullins and Beema, which have better power-management features than previous chips, Lensing said. The clock speeds -- which exceed 2GHz on some chip variants -- can scale up quickly when performance is needed. AMD has cut down on components, and there is a better balance of power and performance.

The integrated graphics cores have better video streaming, bandwidth management, upscaling and filtering features. The cores can improve the quality of video without a user touching it, Lensing said. The chips have the latest GCN (Graphics Core Next) cores, which are variants of technology used in Radeon graphics processors.

Beema and Mullins also have an on-chip security layer to protect systems from being compromised. The hardware layer, built on ARM's Cortex-A5 core, also helps in secure boot, and authentication.

The new Mullins chips include:

- 2.2GHz quad-core A10 Micro-6700T R6, 4.5 watts, 2MB of cache, 500MHz GPU clock speed

- 1.6GHz quad-core A4 Micro-6400T R3, 4.5 watts, 2MB of cache, 350MHz GPU clock speed

- 1.4GHz dual-core E1 Micro-6200T R2, 3.95 watts, 1MB of cache, 300MHz GPU clock speed

The Beema chips include:

- 2.4GHz quad-core A6-6310 R4, 15 watts, 2MB of cache, 800MHz GPU clock speed

- 1.8GHz quad-core A4-6210 R3, 15 watts, 2MB of cache, 600MHz GPU clock speed

- 1.5GHz quad-core E2-6110 R2, 15 watts, 2MB of cache, 500MHz GPU clock speed

- 1.35GHz dual-core E1-6010 R2, 10 watts, 1MB of cache, 350MHz GPU clock speed

All the chips have 128 graphics cores and support DDR3 memory. Pricing on the chips was not provided by the company.
