First Photo of Nvidia’s Next Gen Flagship Pascal GPU Reveals GDDR5X Memory On Board
First photograph of Nvidia’s next generation Pascal GP104-400 GPU has surfaced on the web, which reveals the upcoming flagship GPU won’t support HBM2, but the GDDR5X memory.
The graphics processor is believed to be the main chip powering the GeForce GTX 1080. Being the most powerful GP104 variant, it will have GDDR5X memory on board while other less powerful variants will stick to the conventional GDDR5 memory.
That being said, the GTX 1080 may gain a substantial boost in memory bandwidth due to its cutting edge technology. Leaked pictures also reveal that GP104-400 will be using Micron 6GA77 79TXT modules. However, these modules have not been listed in official product catalog so we don`t have any idea about the speed of these chips.
According to the report, these modules are however slightly different in size than normal GDDR5 memory modules.
In a recent leak, a cut down version of GP104-400 was also revealed which is dubbed GP104-200-A1. This variant of GP104 is rumored to be powering GTX 1070, and if previous reports are to be believed then this graphics chip could feature 20nm GDDR5 memory from Samsung.
The GTX 1070 will use 8GB of DRAM clocked at 2GHz, with memory bandwidth of around 256 GB/sec is expected on the upcoming card over a 256 bit memory interface. In comparison, GTX 1080 will feature 8 GB of GDDR5X memory on a 384 bit memory bus, for a total of 320 GB/sec of bandwidth.
Further, GP104 GPU is expected to feature 2560 cuda cores in total, and around 8 billion transistors.
Nvidia is set to reveal its GP104 based GTX 1070 and GTX 1080 graphics cards at Computex 2016 with product availability in mid-June.
