AMD introduces thin and efficient Radeon Pro 400 GPUs




AMD has announced a new line of GPUs, the Radeon Pro 400 series. There appear initially three models, one of which makes its debut in the 15 “MacBook Pro. AMD claims the Polaris GPUs have made thinner and more economical.

AMD produces the Radeon Pro-GPUs applied to a 14nm FinFET-process and which has thinning in the manufacture. Here, the thickness of the wafers is reduced in size from 780 micrometers to 380 micrometers. This enables manufacturers to design thinner laptops, all-in-ones and small form factor PCs or to use the space differently. The GPUs have tdp’s of less than 35W.

They are the first to Polaris-based GPUs for laptops which meant , but AMD focuses on use for graphics professionals. The first laptops using the GPUs equipped its new MacBook Pro models with 15.6 “screen. By default, this model Radeon Pro 450, but more expensive versions, the Pro 455 and 460. Apple claimed that the new laptop at the rendering 3D graphics 130 percent better performance than the old 15 “-MacBook Pro.

The previous standard GPU MacBook Pro was the Radeon M370x, who with 1024 GFLOPS has a similar pure power, but probably a lot higher consumption. In addition, brings the Polaris-architecture enhancements relative to the Southern Islands’ Cape Verde’-GPU where the M370x is based on. This makes the raw performance is not significantly improved, but there are introduced optimizations for specific applications. AMD introduced the architecture of the GPUs already in 2012.

When arriving at Polaris-based GPUs for consumer laptops is not yet known. Last summer revealed AMD Radeon RX 480M, which is also a Polaris 11 GPU with TDP of 35W, but this has not been officially released.
