Radeon M400 Series Mobility GPUs Confirmed By AMD
We previously reported that Radeon M400 mobility range will be rebranded with only high end chips featuring the next gen Polaris architecture. Now, specifications of these discrete mobility GPUs have officially been confirmed by AMD, with the majority of chips being rebrands of the existing Radeon 300 series lineup.
AMD’s new mobility line consists of several R9 and R7 chips. These chips will be integrated on mobile platforms ranging from low performance to high performance, including Polaris based chips, as well.
The Radeon 400 series mobile lineup includes a total of 11 SKUs based on different GPUs. Since most of the chips are re-brands of existing Radeon 300 mobility series lineup, it pretty much means that low end cards will be same as the last year.
Only the high end chips will be shipping with the new Polaris architecture with 2.5 times efficiency, which are aimed at the mainstream and high performance market.
The AMD Radeon 400 series based on Polaris architecture will be the part of GCN 4.0 family. The GCN 4.0 family is completely re-designed with updated main processor, new geometry processors and other updates inside the core blocks.
The latest Polaris architecture includes an updated primitive discard accelerator, hardware scheduler, instruction pre-fetch, improved shader efficiency and memory compression technology.
These Polaris GPUs are manufactured on the latest 14nm FinFET processor node, which delivers incredible improvements in density of the transistors, leading towards much less power consumption compared to existing nodes.
