Qualcomm reveals quad-core Snapdragon S4 Play processors, ramps up entry smartphone speeds
Don't think Qualcomm is limiting its quad-core processors to superstar phones. The Snapdragon S4 Play line is growing to include the MSM8225Q and MSM8625Q, parallels to the existing two Play chips that bring four cores to entry-level devices. Besides the speed improvements that you'd expect from all that extra parallelism, the Q variants support the extra bandwidth of low-power DDR2 (LPDDR2) memory and can handle both 720p displays and movie-making. Neither is quite an all-encompassing solution, although the two will cover the bases for much of the starter demographic: while local wireless such as Bluetooth, FM radio and WiFi have to remain separate from the main processor, the two newcomers manage to pack either single-mode UMTS 3G (in the 8225Q) or dual-mode CDMA and UMTS (in the 8625Q) for their cellular fix. Along with the already promised, China-focused S4 Plus MSM8930, test samples of the faster S4 Play editions will be ready before the end of the year, with shipping phones on the way in early 2013 -- just in time to go head-to-head with a similar push by MediaTek to make quad-core the norm for a much larger slice of the population.
Anandtech: Apple iPhone 5 features 1GB of RAM, A6 is a custom SoC
Unsurprisingly, Apple left us in the dark regarding some specifics of the iPhone 5 upon its release. Thankfully, the good folks over at Anandtech have done a bit of digging into those numbers you see bordering Apple's Apple A6 SoC, definitively figuring out that Cupertino's latest phone packs in a total 1GB of Samsung-sourced memory. The site clocks the DRAM inside at 1,066Mhz, noting that it's comprised of "two 512MB dies in a dual-channel LPDDR2 package with 32 bits per channel." Further, Anandtech lists the speed of the iPhone 5's memory at 8,528MB/sec -- an ample 33 percent boost over the 6,400MB/sec rating for the RAM in the iPhone 4S, but well below the 12,800 MB/sec needed to drive the new iPad's bandwidth-hungry screen resolution. Beyond that, the site believes that the A6 is Apple's first truly in-house creation, as it's using math units too new to be found in a ARM Cortex-A9 architecture (like the A5 or A5X) but reportedly isn't a match for the soon-to-be-released Cortex-A15. If true, the implication is significant -- it suggests Apple is taking the more aggressive path of a chip designer like Qualcomm and custom-tailoring large parts of its processor designs to get the speed it wants on a more exacting schedule. That's a quick summation of the details; hit up the source links below if you want the explanation in full geek speak. Jon Fingas contributed to this post.
Samsung mass-produces 4-gigabit LPDDR2 memory, aims to make 2GB a common sight in smartphones
Samsung started making 2GB low-power mobile memory last year, but as the 1GB-equipped phone you likely have in your hand shows, the chips weren't built on a wide-enough scale to get much use. The Korean company is hoping to fix that now that it's mass-producing 20-nanometer, 4-gigabit LPDDR2 RAM. Going to a smaller process than the 30-nanometer chips of old will not just slim the memory down by a fifth, helping your smartphone stay skinny: it should help 2GB of RAM become the "mainstream product" by the end of 2013, if Samsung gets its way. New chips should run at 1,066Mbps without chewing up any more power than the earlier parts, too, so there's no penalty for using the denser parts. It's hard to say whether or not the 20nm design is what's leading to the 2GB of RAM in the Japanese Galaxy S III; we just know that the upgraded NTT DoCoMo phone is now just the start of a rapidly approaching trend for smartphones and tablets.
Elpida starts shipments of next-gen Wide IO Mobile RAM
Tablets might be all sexy curves and Gorilla Glass, but it's what's on the inside that counts, right? Efficient DRAM mightn't set your heart alight, but Elpida Memory did just start shipping its next generation 30nm "Wide IO Mobile RAM." The firm claims it uses 50 percent less power compared with equivalent DDR2 sticks, letting you caress your beloved device for longer. This economy is thanks to it purring along at just 200MHz, which is even more impressive when you consider it brags a 12.8 GB/s data rate per chip. This pumped, yet frugal, performance comes courtesy of using x512-bit data width -- some ten times larger than that of existing DRAMs. The party doesn't stop there, with the Elpida also debuting its LPDDR3 chip, brushing aside LPDDR2 with twice the data rates at 6.4GB/s a slice, and a 25 percent smaller power-drain in tow. Mass production should commence in 2012, check the source link for the full break-down.
Samsung starts baking 30nm 4Gb LPDDR2 chips, packaging 2GB mobile RAM in April
When it comes to mobile RAM, capacity is often what pops to mind first while we overlook speed and power consumption, but Samsung's latest delivery is worth the extra attention. Earlier this month, said Korean giant started producing 30nm 4Gb 1066Mbps LPDDR2 (or simply Mobile DDR2) chips, in order to phase out its 40nm ones that topped 2Gb at a 800Mbps transmission rate. To put it in perspective, a 40nm 1GB package consists of four 2Gb chips, whereas the new 30nm one will only need two 4Gb chips, thus reducing the package thickness by 20 percent (down to 0.8mm) and power consumption by 25 percent. It's hard to tell when we'll start seeing these bits of silicon entering the consumer market, but Samsung's already stamping out 1GB modules this month, with a 2GB version to follow next month. Oh yes, we're definitely liking the sound of 2GB RAM for mobile phones.
Hynix ships fastest one-gigabit LPDDR2 chip for mobile devices
Though not quite as impressive as the idea of toppling Intel and AMD within the next ten years, Hynix Semiconductor still has a decent reason to brag today. The South Korean chip producer has announced that it has just started mailing out the "fastest data transferring advanced dynamic random access memory (DRAM) chip for mobile devices." Said chip is the one-gigabit LPDDR2 (low-power double-data-rate 2), which was crafted using 66-nanometer technology and features an 800-megabits per second operating speed at 1.2-volts. No word on exactly what devices will see the super-speedy chip packed within, but a company spokesperson did note that it plans on ramping up production during Q4 to meet "growing demand for flat-panel television sets and high-end handheld devices."[Via Physorg]
