Samsung’s CES keynote was an overall consider the function the business is doing about a range of fronts. CPU development was front plus center, including the announcement of the fresh Exynos 5 Octa. This fresh chip is the initial SoC to apply ARM’s big.LITTLE architecture from any maker. The Exynos 5 Octa is an eight-core product which pairs 4 Cortex-A7 CPUs with 4 Cortex-A15s. Simple jobs are offloaded to the A7 processors, that consume greatly less force, when the A15s angle up for heavy lifting.
Like the elder Cortex-A8, the A7 is a easy in-order shape. It’s capable of issuing 1-2 instructions per clock cycle, has an 8 stage pipeline, plus an integrated FPU. It’s feature suitable with all the A15; application programmers won’t need to change their code to target the A7 inside certain. Clock speeds are rumored to be about 1.2GHz for the A7 cores plus 1.8GHz for the A5s.
How perfectly it functions depends how sophisticated plus flexible the flipping program is. It’s not well-defined when Android, Windows Phone 8, or Windows RT could preferentially target 1 set of cores over the different, or whether the SoC may use the A7 plus A15 cores simultaneously. Ideally, jobs like drive notifications might target the A7, regardless of what, freeing up the A15 to focus about gaming or HD decoding.
Nvidia’s Companion Core targets the same idea because big.LITTLE, however from a different angle. Tegra 4′s fifth core is equally a Cortex-A15, albeit an optimized chip that’s crafted for lower voltage plus clock speed targets. The total implementation is synonymous to what you saw with Tegra 3. A slow Cortex-A15 will surpass the quick A7 — however how about 2-4 of them? That’ll hang about CPU optimizations, multi-threading help, plus load balancing.
Intel, meanwhile, has earlier reported it doesn’t should apply the big.LITTLE or Companion Core shape to hit its energy expenditure targets. Medfield was commonly competitive about this front; we’ll need to wait plus see how next-generation dual-core Atom phones compare to these new components.
Display technology: Onward, upward, rolled up inside the pocket
4K tvs? Check. OLED displays? Check. The more interesting show technologies were Samsung’s demonstration of flexible displays plus several hot info about LCD force efficiency improvements.
The flexible displays the business demoed are produced by Yuon plus is bent, twisted, plus folded. That last 1 is a new capability; past displays have been bendable, yet haven’t been capable of folding flat. Samsung is investing seriously inside Yuon, however didn’t provide any info about whenever you may see these modern displays included into items.
Samsung claims which the Nexus 10′s show utilizes simply 75% because much force because typical LCD panels, plus which the organization is functioning about development to cut which figure another 25 percentage points.
We speak a lot regarding CPU force efficiency, however the central processor is just 1 component from several inside contemporary smartphones or pills. While it’s true which CPUs at full load will chew from big amounts of power energy, Intel, Nvidia, plus ARM itself have all invested a lot of cash into acquiring methods to ensure chips spend because small time at full force because potential.
Display force plus brightness today account for a considerably greater amount of total energy usage than the CPU, as well as the trend towards high-density displays has just created the difference more lopsided. A 25% show energy reduction might translate into real power lifetime improvements — offered which Samsung didn’t instantly obviate the gain by ratcheting up pixel densities into the stratosphere.
No cost tags or release dates for OLED or 4K, by the technique — nevertheless with LG actually launching a product inside the upcoming couple months, you are able to bet Samsung is viewing carefully. If it looks like customers are leaping to purchase (comparatively speaking), we’ll see more OLED HDTVs moving to marketplace.
Overall, Samsung’s keynote was strong, however, it echoes a theme we’ve enjoyed cropping up at CES 2013 from multiple organization. A lot of the conversation is focused about future items plus technologies because opposed to concrete release dates plus almost completed hardware. That doesn’t signify hot treatments aren’t coming, nevertheless many firms appear to be playing it secure. On the different hand, we’re not going to complain whenever producers don’t promise impossible ship dates.
