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) A slide showing the earlier codename "volta" - circa 2013 (via Anandtech) A slide from GTC 2014 showing the "Pascal" architecture after Maxwell (via Anandtech) 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...

After the announcement of Nvidia's Tegra K1 , aka Logan at CES in January , the chip company didn't reveal any further details about their next mobile cpu. Along with the announcement of the Pascal GPU architecture ,Nvidia announced details about the next generation Tegra mobile processor codenamed Tegra Erista .If you are into comics , Erista is the Son of Logan , And Logan in Nvidia's case is the codename for Nvidia Tegra K1 ,The K1 was the first Tegra chip to feature the 192 Kepler GPU cores and was designed using the 64Bit ARMV8 architecture .Erista on the other hand also uses the ARMV8 64Bit design , but the Erista uses Nvidia's Maxwell GPU , the Maxwell GPU cores were announced in 2013 , but now it seems the GPU technology has shifted to mobile use . The Tegra Erista will support DirectX 12 and will also support Unreal Engine 4 for mobile . The chipset is due for launch in 2015 (hopefully at CES next January),The Tegra K1 is scheduled for launch in Q2 of this...
