This is not a typical press release that is approved by both parties. It's an RNS as i mentioned. I'm trying to find the a counterpart that Samsung has posted. There isn't one. It seems this is a mere attempt to try and disrupt ARM's announcement.
This could be make it or break it for ARM graphics business which bought the small graphics chip design company 3 years ago. This could have the performance which the market is looking for unlike their previous offerings which were on the lower end of the scale.
A small power efficient graphics core would certainly boost the handling of visual data on the handhelds wihtout burning a significant hole in the power budget.
Samsung haven't announced anything! Imagination issued an RNS to the LSE.
The fact there is no press release on the Imagination website, shows there is no real substance behind this "announcement" and Samsung would have done the same if there was something worth shouting about.
Recent A15 announcements from ARM (Freescale, HiSilicon, TI...) do not include any mention of ARM GPUs. Given ARMs PR push on next generation Mali GPUs these must be Imagination or Vivant design wins? As fulguy mentions, Samsung/ST are switched from Mali to Imagination. NVIDIA, Broadcom and Qualcomm have traditionally developed their own GPUs.
