MediaTek launches world’s first true octa-core mobile chip, first devices due end of year

Posted on 20/11/2013 by Richard Lai

Qualcomm's nightmare has finally come true. Earlier today, MediaTek officially introduced the world's first true octa-core mobile processor, MT6592, and the first devices to feature it are expected to arrive as soon as end of year. This 28nm chip packs eight low-power Cortex-A7 cores, and courtesy of the Heterogeneous Multi-Processing use model on top of ARM's big.LITTLE architecture, all eight cores can operate simultaneously -- at up to between 1.7GHz and 2GHz, depending on the bin.

MediaTek pointed that Chrome can already make use of all eight cores, and likewise with some map apps, video players plus multi-window function. According to the company's figures, the MT6592 manages to beat what appears to be the quad-core Snapdragon 800 in benchmarks, power consumption (as low as 40 percent) and temperature.

Exynos 5 Octa demos 8 cores working at once and other feats of CPU strength (video)

Posted on 11/09/2013 by Richard Lawler

Just in case yesterday's news that Samsung is ready to enable new features on its Exynos 5 Octa chips wasn't clear, ARM has published a few demo videos to show what it can do. All three are embedded after the break, and the first one highlights how the Exynos 5 Octa 5420 can activate some or all of its 8 cores to maximize responsiveness while launching and using Quickoffice. As you can see above in the screenshot, all eight cores are activated while launching the app, then unused ones switch off for more efficiency. Another video shows how it runs Angry Birds Rio on just the four Cortex-A7 "LITTLE" side of the CPU, rarely activating any of their more power-hungry A15 friends. The last demo video shows how its Mali-T628 GPU activates to process images faster and more efficiently than the CPU alone can.

Samsung’s Exynos 5 Octa CPUs will be able to use all eight cores at once in Q4

Posted on 10/09/2013 by Richard Lawler

We'll have to change our terminology for Samsung's Exynos 5 Octa mobile chips now. We've been calling them "not-quite" eight core CPUs since they can't actually use all eight at once, but the company's new Heterogeneous Multi-Processing solution is going to change that. Once it's available in Q4 it will let devices access both sides of the big.LITTLE ARM configuration simultaneously, which it claims will increase both performance and efficiency. While software threads with high priority use the "big" A15 core, lower priority tasks can run on the "small" A7 without needing to switch back and forth. Samsung isn't the only one running this setup however, as MediaTek announced an implementation for its MT8135 back in July. There are more details included in the press release (after the break) but we're not seeing any confirmation if this will ever be enabled on existing / announced devices like some flavors of the Galaxy S 4 or the Meizu MX3. Either way, the folks at Qualcomm might want to put together another video.

Qualcomm trolls MediaTek’s octa-core tech with not-so-subtle video

Posted on 29/08/2013 by Richard Lai

When MediaTek announced that it would be producing true eight-core mobile processors later this year, we knew it was only a matter of time before its main rival Qualcomm chimed in. As illustrated by a set of guitar amplifiers, the San Diego gang explains that while they rebuild their CPU cores for each generation (the latest architectures being Krait 300 and Krait 400), they claim that "Our Competitor" -- which is labeled with the same font and colors as MediaTek's logo -- simply "chooses to duplicate the same old cores" based on ARM's slower Cortex-A7 architecture. That said, it's worth a reminder that Qualcomm's cheaper Snapdragon 400 range also uses Cortex-A7.

Later on in the video, Qualcomm uses a Guitar Hero-like visualization to compare the performance difference, as well as show how octa-core is overrated for most apps. Apparently only 17 out of the top 20 Android apps in China use two cores at most, hence the bare fretboard for the octa-core side. The Snapdragon side, meanwhile, combs through a denser bunch of apps at a higher speed. Of course, there's bound to be some bias here, so only time will tell how close to reality this argument is. Until then, enjoy the cheeky clip after the break.

Samsung caught boosting benchmark performance numbers on Exynos devices

Posted on 30/07/2013 by Brad Molen

Benchmarks often catch the ire of critics because their scores don't necessarily reflect real-world experience, and it appears that some Samsung devices aren't helping that reputation out at all. Our friends at Anandtech started sifting through data for two Exynos octacore variants of the Galaxy S 4, and discovered multiple benchmarks that appear to run those devices at higher CPU and GPU clock speeds than they normally run. Some of the apps included in the report are GLBench 2.5.1, AnTuTu, Quadrant and Linpack. Coincidentally, the site also found code within the GS4 that indicates the existence of a program called "BenchmarkBooster," which is responsible for overclocking the processors when certain apps are running. Is this an evil plot by Samsung to take over the world using rogue benchmarking results? Is this something other manufacturers are doing? It's hard to say, but there is certainly something curious afoot. Check out the source to get all of the skinny on what exactly is going on.

MediaTek confirms true octa-core processor in the works

Posted on 27/07/2013 by James Trew

Earlier this month there was a whisp of octa-core colored smoke coming from MediaTek. Today it's more of a roaring camp fire, with the chip-maker going official -- fully announcing its new octa-core processor ambitions. The firm stops short of giving us the actual nitty-gritty specifications that many of you will be waiting for, instead taking the chance to remind us that Arm-based chips will be true eight-cores-at-once processing, and none of this big.LITTLE dallying. The word is these will float around the 2GHz mark on arrival, which last we heard was pegged for November. We're not suggesting the timing of this announcement was planned, but it looks, for now, like 8 is the current lucky number.

Samsung Galaxy S 4 with Exynos Octa-core: what’s different?

Posted on 06/05/2013 by Brad Molen

More Info

Samsung's latest flagship, the Galaxy S 4, comes in two distinct flavors -- and they're both good. One uses the much-hyped Exynos Octa-core chip, while its identical twin takes advantage of the quad-core Qualcomm Snapdragon 600. In either case, the availability depends on where you live: the Exynos-powered I9500 is difficult to find in North America (at least for now), but our friends at Negri Electronics, an online retailer currently stocking the Octa-core device, gave us the opportunity to play with a unit for a few days. During our time with the device, we were able to get a solid feel for how this particular version of Samsung's flagship compares to the Snapdragon 600-powered model. So how does it hold up against its Qualcomm brother in terms of performance and battery life? Read on to find out.

AMD FX-8350 review roundup: enthusiasts still won’t be totally enthused

Posted on 23/10/2012 by Steve Dent

Now that AMD's fresh new FX processors based on the Piledriver architecture are out in the wild, the specialist hardware sites have seen fit to benchmark the top-lining FX-8350. Overall, the group feels that AMD has at least closed the gap a bit on Intel's Core juggernaut with a much better FX offering this time around, but overall the desktop CPU landscape remains unchanged -- with Intel still firmly at the top of the heap. Compared to its last-gen Bulldozer chips, "in every way, today's FX-8350 is better," according to Tom's Hardware: cheaper, up to 15 percent faster and more energy efficient. Still, while the new CPUs represent AMD's desktop high-end, they only stack up against Intel's mid-range Core i5 family, and even against that line-up they only edge ahead in heavily threaded testing. But if you "look beyond those specific (multithreaded) applications, Intel can pull away with a significant lead" due to its superior design, says Anantech. As for power consumption, unfortunately "the FX-8350 isn't even the same class of product as the Ivy Bridge Core i5 processors on this front," claims The Tech Report.

Despite all that, Hot Hardware still sees several niches that AMD could fill with the new chips, as they'll provide "an easy upgrade path for existing AMD owners and more flexibility for overclocking, due to its unlocked multipliers." That means if you already have a Socket-AM3+ motherboard, you'll be able to do a cheap upgrade by swapping in the new CPU, and punching up the clock cycles might close the performance gap enjoyed by the Core i5. Finally, AMD also saw fit to bring the new chip in at a "very attractive" $195 by Hexus' reckoning, a much lower price than an earlier leak suggested. Despite that, however, the site says that AMD's flagship FX processor still "cannot tick as many desirable checkboxes as the competing Intel Core i5 chips." Feel free to scope all the sources below to make your own conclusions.

AMD updates its FX processors: 8-core chip has 4GHz base clock, ’15 percent’ more oomph, $195 price tag

Posted on 23/10/2012 by Sharif Sakr

If you get the impression that AMD is diverting its energy away from traditional CPUs and towards APUs and fresher PC form factors such as all-in-ones, then you're certainly right -- but you're also slightly ahead of the game. The company promises there's a still a good few years of life left in its CPU-only chips and the AM3+ socket, and it's putting today's announcement forward as evidence. As of now, last year's eight-core FX-8150 has been superseded on retailers' shelves by the FX-8350, which notches the stock clock speed up to 4GHz, or 4.2GHz on turbo (alas with no obvious sign of that resonant mesh we once heard about). The full stack (codenamed 'Vishera') includes eight-, six- and four-core options, all based on the new Piledriver architecture which -- when combined with these higher clock speeds -- promises an overall performance uplift of around 15 percent versus the old Bulldozer cores. To be fair though, those Bulldozers weren't so snappy to begin with, and besides, the most significant performance claims with this upgrade relate to multi-threaded applications and a few gaming titles like Skyrim and Civ 5. Judging from the slide deck below, gains in other areas of performance may be lower -- perhaps in the region of seven percent -- so as usual we're going to roundup a bunch of reviews later today before we jump to any conclusions.

If it turns out that stock performance alone isn't enough to sell these chips, then potential buyers still ought to check out FX's pricing relative to Intel -- not least because, as is typical, AMD sells overclockable chips at no extra charge. The top-end FX-8350 will hit the market at $195, which is not only cheaper than some earlier leaks suggested, but also $40 cheaper than an unlocked Core i5-3570K that has a lower clock speed and a smaller L3 cache -- although the relative performance of these two chips remains to be independently tested. Meanwhile, the entry-level quad-core FX-4300 will virtually match the price of a locked i3-2120 at $122, but can be readily overclocked to 5GHz with water-cooling. AMD is also making a few claims based on the cost of multiple components in a rig: for example, that you can spend $372 on an FX-8350 and Radeon HD 7850 combo that delivers a 25 to 70 percent gaming advantage over a similarly priced Core i5 3570K with a GeForce GTX 650 Ti. Again, stay tuned for our roundup and we'll figure out just how compelling this really is.
