@ 2012/08/07In our discrete GPU reviews for the desktop we've often noticed the tradeoff between graphics and compute performance in GPU architectures. Generally speaking, when a GPU is designed for compute it tends to sacrifice graphics performance or vice versa. You can pursue both at the same time, but within a given die size the goals of good graphics and compute performance are usually at odds with one another.
Mobile GPUs aren't immune to making this tradeoff. As mobile devices become the computing platform of choice for many, the same difficult decisions about balancing GPU compute and graphics performance must be made.
ARM announced its strategy to dealing with the graphics/compute split earlier this year. In short, create two separate GPU lines: one in pursuit of great graphics performance, and one optimized for graphics and compute.
Today all of ARM's shipping GPUs fall on the blue, graphics trend line in the image above. The Mali-400 is the well known example, but the forthcoming Mali-450 (8-core Mali-400 with slight improvements to IPC) is also a graphics focused part.
The next-generation ARM GPU architecture, codenamed Midgard but productized as the Mali-T600 series will have members optimized for graphics performance as well as high-end graphics/GPU compute performance.
