Samsung slips into AMD's HSA party, may seek parallel processing boost for Exynos
Trust us, this should ultimately make a lot of sense. As we already know, AMD recently set up the HSA Foundation to promote its vision for better parallel processing -- and especially GPU compute -- in mobiles and PCs. Its semi-rival ARM was one of the first big players to join up, and now Samsung has decided to hop onboard too. Why would it do that? For the simple reason that the Korean company still makes its own chips, based on ARM designs, and we've seen that GPU compute is going to be a big feature in its coming Exynos 5 processor with Mali T604 graphics. Now, anything else at this point is pure speculation, since we only know about Samsung's HSA membership from the appearance of its logo on a relevant slide at AMD's keynote speech at IFA, and there's no official word on Samsung's intentions. At a bare minimum, the company could simply be firming up friendships and hedging its bets on the future of computing. We wouldn't be surprised, however, if Sammy is looking to work with ARM and AMD to implement further aspects of the HSA philosophy into even more advanced Exynos chips down the line -- chips that are able to use both GPU compute and smaller transistors to achieve leaps in performance while also gobbling fewer volts.
Rivals AMD and ARM unite, summon others to become 'heterogeneous'
Rumors of a hook-up between AMD and ARM have been circulating ever since someone coined the phrase "the enemy of Intel is my friend." As of today, however, that alliance is real and cemented in the form of the HSA Foundation -- a non-profit organization dedicated to promoting the dark arts of Heterogeneous System Architecture. It's a relatively old concept in computing, but the Foundation's founding partners (AMD, ARM, Imagination Technologies, MediaTek and Texas Instruments) all stand to gain from its wider adoption. How come? Because it involves boosting a chip's performance by making it use its various components as co-processors, rather than treating them as specialized units that can never help each other out. In other words, while Intel pursues Moore's Law and packs ever-more sophisticated transistors into its CPUs, AMD, ARM and the other HSA pals want to achieve similar or better results through parallel computing. In most cases, that'll mean using the graphics processor on a chip not only for visuals and gaming, but also for general tasks and apps. This can already be achieved using a programming language called OpenCL, but AMD believes it's too tricky to code and is putting mainstream developers off. Equally, NVIDIA has long had its own language for the same purpose, called CUDA, but it's proprietary. Whatever niche is left in the middle, the HSA Foundation hopes to fill it with an easier and more open standard that is not only cross-OS but also transcends the PC / mobile divide. If it works, it'll give us a noticeable surge in computational power in everyday apps by 2014. If it fails, these new-found friends can go back to the less awkward custom of ignoring each other.
