Photos indicate Nvidia GeForce GTX 1080 with gddr5x and GTX 1070 with GDDR5
From online published pictures of the GP104-GPUs, which will probably be applied to the 1080 GTX and GTX 1070, is to make that Nvidia chooses gddr5x on the top model. The GTX 1070 will as the current generation of video cards GDDR5 memory.
Nvidia GP104-400 Wccftech published the photo of the GP104-400 GPU. The chip is placed on a PCB, and is accompanied by gddr5x memory chips from Micron. Earlier rumors talked about a 1080 GTX gddr5x with 8GB memory and that now seems confirmed. In February Micron made known to start the summer with the mass production of the new memory. According to the manufacturer speeds of 13GB / s were obtained with test chips. What speed memory on the GTX 1080 will receive is not yet known.
Videocardz discovered that the leaked photo is a custom PCB. It would be a variant of MSI, as the placement of components corresponds exactly to the PCB from an MSI GTX 980 4GB. Probably video card manufacturers over the new Pascal GPUs already owned and they are engaged in the production of their new cards.

Chip Hell – GP104-200 Chiphell.com came through an image of the GP104-200 GPU to outside . This chip will probably find its way to the 1070 GTX cards. There is also seen a photograph of the GPU on the pcb, wherein the memory chips are in the picture. Although the image is not very sharp, it goes according Videocardz to GDDR5 memory from Samsung with a capacity of 8GB.
The GP104-200 GP104-400 and have the same dimensions. Judging by the size of the package is to calculate how many transistors, the GP104 contains about. The chip is in fact based on the GP100, whose -dimensions which and the number of transistors are known. According to the calculations is that of the GP104 approximately 317mm 2 in size and has these transistors approximately 8 billion. The full GP100 GPU 15.3 billion transistors 610mm 2 in size.
Presumably the GP104 gets significantly higher clock speeds than the current generation Maxwell cards. The GP100 GPU gets on the Tesla P100 card for servers and workstations at speeds of 1328MHz and 1480MHz for boost. The clock speed of Tesla cards for the professional market is generally lower than GeForce cards with the same GPU architecture.

Nvidia will probably end of May, just before the start of the Computex trade show in Taiwan, its new GeForce cards announcing . It is expected that the video cards around June will find their way to the shops. Possibly the GTX 1080 with later gddr5x memory, given Micron shows the mass production of this type of memory for this summer are planned.Viewing:-160
