NVIDIA Tegra 4 processor details leaked: 4-plus-1 cores, 28nm, six times the power of Tegra 3

NVIDIA’s next superhero-themed mobile chipset has possibly made an early appearance in a leaked side in China, and it looks like it wants to go toe-to-toe with the latest processors from Samsung and Qualcomm. The Tegra 4 (codenamed Wayne) will apparently offer the same power-efficient 28nm process found on its Snapdragon rival and according to the slide from Chip Hell , there’s a dizzying 72-core graphics setup. That’s apparently 20 times the power found the Tegra 2 and six times that in the last-generation Tegra 3, which powered, among other devices, the Nexus 7 . Those graphics cores will be able to power screens up to 2,560 x 1600, with 1080p output at 120Hz, while the leak also mentions 4K — if only in passing. We won’t see any increase in CPU cores this time, with the same 4-plus-1 setup , but we are likely seeing a move to ARM’s latest design, the Cortex-A15 . It’ll also catch up with USB 3.0, being NVIDIA’s first mobile chip to do so, alongside dual-channel DDR3L memory. We’ve reached out to chipmaker and we’ll let you know when we hear more, but it’s highly likely we’ll be seeing this next-generation processor early next year — say, at a mobile trade show .

Linux to drop i386 support in the 3.8 kernel, make us upgrade our Doom rig

Linux has developed a reputation for running on just about anything . If proposed changes to the 3.8 kernel take effect, we’ll have to add an “almost” disclaimer. The OS’ maintainers expect to drop support for Intel’s i386 architecture with the new release, noting that there’s “quite a bit of complexity” that could be lifted by swinging the focus to (much) newer chips. Don’t expect Torvalds to have much nostalgia for i386 despite basing much of his early work on it, either, as he’s bidding “good riddance” to the legacy code. We can’t blame the Linux collective for wanting to drop support for 27-year-old silicon that’s well out of fashion, even in embedded components; you’ll just have to forgive us if we shed a tear for that retro gaming PC which finally fell off the update bandwagon.

Leaked chart appears to spill beans on Intel’s Haswell desktop CPU range

The folks over at VR-Zone have snagged a chart which purports to represent Intel’s plans for the Haswell architecture in 2013. If genuine, then we can expect at least 14 new desktop CPUs to arrive next year, including a range-topping 3.5GHz Core i7 with 400MHz of headroom in boost mode and a TDP of just 84W — i.e. midway between Sandy and Ivy Bridge in terms of power consumption, but not bad when you consider this’ll be a higher performance architecture with no transistor shrinkage . Integrated graphics have also apparently been tweaked, with a reference to HD 4600. Since we can’t expect Intel to confirm the leak, we’ll just have to file this one in the “plausible” cabinet. (What, you didn’t know we had filing cabinets?) Comments Via: Ubergizmo Source: VR-Zone (Translated)

Take that linear algebra to go: Intel’s 48-core chip targeting smartphones and tablets

Intel’s taking its 48-core processor and applying it to a field beyond academia : the world of mobile electronics. The company this morning announced intentions to slip the 48-core bad boy into future tablets and smartphones (emphasis on future ), with CTO Justin Rattner saying the mobile implementation could arrive “much sooner” than the 10-year window predicted by researchers. Aside from the thrilling world of linear algebra and fluid dynamics that the chipset is currently used for, Intel says it could offload processor-intensive functions across several cores, effectively speeding up various functions (say, video streaming). The availability of so many cores also means faster multitasking possibilities than the current dual- or quad-core offerings in modern smartphones and tablets — just imagine a world where two Angry Birds games can run simultaneously in the background without affecting the paradoxical game of Tiny Wings you decided to play instead. Hey, we understand — it’s just a better bird game. No big. Sadly, few software developers are crafting their wares (warez?) to take advantage of multi-core processing as is, so it’s gonna take more than just the existence of Intel’s 48-core chip to make its vision a reality.
