Advanced Micro Devices on Tuesday unveiled two new families of accelerated processing units with low and ultra-low power consumption. The new chips, previously known as Beema and Mullins, will power thin laptops, 2-in-1s, as well as various Microsoft Windows-based tablets. Unfortunately, the majority of actual devices based on AMD’s new chips will only emerge on the market sometimes late in Summer.

AMD “Beema” and “Mullins” APUs will feature two or four x86 cores based on the new Puma+ micro-architecture (out-of-order/speculative execution with two-way 128-bit wide floating-point and packed integer execution) that closely resembles Jaguar and supports numerous new instructions previously only available on high-performance x86 micro-architectures. The Puma micro-architecture further optimizes power consumption compared to previous-generation Jaguar cores; for example, AMD claims that Puma sports 19% lower CPU core leakage.
