Nvidia next gen Pascal GPU architecture to be available in 2016


After announcing details about the Tegra Erista mobile processor and a $3000 graphics card , Nvidia published new details about their upcoming GPU architecture called "Pascal" .The GPU design was previously known as "Volta" and it has been slowly replaced by "Pascal" instead (fate of Volta is unknown as of now)

The Pascal GPU is said be the next step in avoiding data bottlenecks when data transferred
between the CPU and GPU slows down the processors ability to perform tasks . The new Nvidia NVLink is a integrated chip to chip communications technology that will eventually replace the PCIe standard by about 80GB per second compared to the 16GB on PCIe. The new Pascal system will also have stacked DRAM chips which are placed in dense modules with wide interfaces, and brings them inside the same package as the GPU. This lets GPUs get data from memory more quickly while retaining a smaller design and better energy efficiency.While combating the physical size by introducing 3D memory packing via Stacked DRAM's , the company will also work on eliminating the need for developers to split resources on CPU and GPU memory by allowing the cpu to access the GOU's memory and vice versa . While all this sounds good , the Pascal GPU architecture will not be available until 2016 .

iPad (2022) and iPad Pro with M2 announced

Apple has announced their latest iteration of the iPad (entry level model) and the iPad Pro lineup with the new M2 processor.

HTC One to sell as TD 101 at China Mobile

HTC decided to invest in such a brand by launching the One series of smartphones last year, although the company was not able to impose its own product names to certain carriers. Then, just a few days ago, the company launched the HTC One, which is going to be the company’s only One-branded handset this year, a make-or-break kind of project for the Taiwanese Android maker that’s still having a tough time fighting against the competition, especially Samsung. We were under the impression that HTC will further invest in its One brand and not budge to carrier demands anymore when it comes to changing the name of the product – in the U.S., AT&T, Sprint and T-Mobile are going to sell it as the HTC One. But it looks like things aren’t necessarily so, and no, it’s not Verizon that’s going to get its way selling the One as the Droid DNA Plus, as it was recently rumored. We’re looking at China Mobile this time around, which has announced the HTC One as the HTC TD 101. That’s certa...
