AMD's next laptop processor is mostly about battery life
Intel isn't the only chip giant championing battery life over performance this year. AMD has revealed Carrizo, a processor range that's focused heavily on extending the running time of performance-oriented laptops. While there will be double-digit boosts to speed, there's no doubt that efficiency is the bigger deal here. The new core architecture (Excavator) is just 5 percent faster than its Kaveri ancestor, but it chews up 40 percent less energy at the same clock rate -- even the graphics cores use 20 percent less juice.
AMD says its next PC chip trumps Intel with 12 'compute cores' and smoother gaming
A decade ago, AMD brought us the first dual-core x86 processor. Then, starting in 2008, the company came out with tri-core and quad-core designs in quick succession, leading up to octa-core chips in 2011's FX range as well as in the latest AMD-powered game consoles. Today, we're looking at a fresh leap forward, albeit one that will take a bit of explaining: a desktop and laptop chip called Kaveri, which brings together up to four CPU cores and eight GPU cores and gives them unheard-of levels of computing independence, such that AMD feels justified in describing them collectively as a dozen "compute cores." Marketing nonsense? Not necessarily. AMD is at least being transparent in its thinking, and besides, if you've been following our coverage of the company's HSA project, and of GPU compute in general, then you'll know that there's some genuine technology underpinning the idea of GPU cores being used for more than just 3D rendering. Nevertheless, even if you don't go for the whole 12-core thing, AMD still makes some down-to-earth promises about Kaveri's price and performance -- for example, that it matches up to Intel chips that cost a lot more (the top Kaveri desktop variant costs just $173, compared to $242 for a Haswell Core i5), and that it can play the latest games at 30fps without the need for a discrete graphics card. These are claims that can -- and will -- be put to the test.
AMD's next desktop chip lands in January, merges CPU and GPU like never before
We've been waiting a long time for the AMD chip known as Kaveri, but at least now we have a date for its availability: January 14th. We also know that the flagship desktop part for FM2+ socket motherboards will be called the A10-7850K, that it'll use four Steamroller CPU cores clocked at 3.7GHz, and that it'll incorporate the same TrueSound audio processing technology found on AMD's latest Radeon graphics cards. What we don't know for sure is how much this A10 chip will cost, or whether it'll arrive first as a standalone part or in pre-built systems. But either way, we're about discover something important: namely, whether the next-gen "Heterogeneous Systems Architecture" (HSA) that AMD has been boasting about, and which is supported for the first time on Kaveri, is actually worth its syllables. Read on for more.
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.
