AMD has officially taken the wraps off its next-generation graphics architecture named Vega at CES 2017.
Vega offers a next-generation compute engine, and boasts a new programmable geometry pipeline which offers twice the peak output per clock.
AMD notes that the R9 Fury X offers four geometry engines and a peak of four polygons per clock. Comparatively, Vega offers the same number of engines, but they can handle up to 11 polygons per clock – a boost of 2.6x – which is a lot more pixel shifting power, and an impressive leap in performance to say the least.
The new architecture boasts high-bandwidth cache and HBM2 video memory that offers twice the bandwidth per pin compared to HBM, and no less than eight times the capacity per stack.
Compared to GDDR5 video RAM, AMD claims HBM2 overall footprint is 50% smaller.
AMD also notes that the high-bandwidth cache controller offers ‘adaptive, fine-grained movement’, and the new cards will benefit from 512TB of virtual address space.
Vega also benefits from a next-gen Pixel engine and other clever bits of tech to help eke out extra performance while keeping a lid on power consumption, such as a draw stream binning rasterizer.
