Apple iPad 2 GPU Performance Explored: PowerVR SGX543MP2 Benchmarked

by

AnandTech: Earlier this morning we published our first impressions on Apple's iPad 2, including analysis on camera quality and a dive into the architecture behind Apple's A5 SoC. Our SoC investigation mostly focused on CPU performance, which we found to be a healthy 50% faster than the A4 in the original iPad - at least in web browsing. We were able to exceed Apple's claim of up to 2x performance increase in some synthetic tests, but even a 50% increase in javascript and web page loading performance isn't anything to be upset about. We briefly touched on the GPU: Imagination Technologies' PowerVR SGX 543MP2. Here Apple is promising up to a 9x increase in performance, but it's something we wanted to investigate...

Amazon Web Services Introduces High Performance Cluster GPU Instance

by

Amazon Web Services: A few years ago advanced developers of numerical and scientific application started to use GPUs to perform general-purpose calculations, termed GPGPU, for General-Purpose computing on Graphics Processing Units. Application development continued to grow as the demands of many additional applications were met with advances in GPU technology, including high performance double precision floating point and ECC memory.

However, accessibility to such high-end technology, particularly on HPC cluster infrastructure for tightly coupled applications, has been elusive for many developers. Today we are introducing our latest EC2 instance type (this makes eleven, if you are counting at home) called the Cluster GPU Instance. Now any AWS user can develop and run GPGPU on a cost-effective, pay-as-you-go basis...
