Imagination claims performance improvement of 60 percent in new smartphone GPU




Chip designer Imagination Technologies PowerVR Series7 has announced gpu designs that are intended, among other mobile devices. The fastest variant, the Series7XT GT7900 contains 512 cores. The new socs were up to 60 percent better performance than the old.

The new Series7 architecture, which has codenamed Rogue inherited, has two variants: Series7XT provides up to 512 aluminum cores, while the energy-efficient Series7XE variant is designed with 16 or 32 aluminum cores. The chip designer claims that the new GPU designs in graphics benchmarks with the same clock speed and cluster size up to 60 percent better performance than its current offer Series6 designs.

PowerVR XT GPUs can be used according Imagination Technologies used not only for midrange and high-end mobile phones and tablets, but also in set-top boxes, consoles and servers. The GPUs would include HDR rendering, and ‘realistic’ 4K texturing possible. The GPU design can handle 10bits yuv color space. The XE and XT GPUs also support both OpenGL 4.4 and OpenGL ES 3.1. Open CL 1.2, a standard for GPGPU applications, is also supported. Also, the new GPUs provide virtualization functions, and optionally supports the XT-variant DirectX 11. When the first SOCS will appear on the basis of the Series7 GPUs has not yet been clear.

The PowerVR GPU designs are used, among other things by Apple for its A series of SOCs and for some Intel Atoms. Texas Instruments, also AllWinner and MediaTek have licenses for the use of the designs.
