Nvidia Pascal GTX 1080 and GTX 1070 To Utilize GDDR5X Memory, Demo Expected Next Week
The debut of the next gen Nvidia Pascal GPUs is just around the corner. CEO Jen Hsun Huang is expected to unveil the Pascal architecture at this year’s GPU Technology Conference (GTC) next week. That being said, a new report has just surfaced on the web which claims that the upcoming Pascal based GeForce GTX 1080 and GTX 1070 will utilize GDDR5X memory.
The information comes from a Swedish website Sweclockers which suggests that the successors to current GTX 970 and GTX 980 cards will support higher-bandwidth memory, GDDR5X, which offers twice the bandwidth and storage over the last gen GDDR5.
This is in line with a previous report from BenchLife, which states that the upcoming GTX 1080 graphics card will be configured with 8GB of GDDR5X memory. Based on the most powerful GP104 configuration, the GTX 1080 is rumored to feature 4096 CUDA cores, 256 texture mapping units, 128 render output units, along with a base clock of 1000MHz for a total of 8.192 teraflops.
Nvidia Pascal is built on 16nm process technology which will enable much reduced power consumption, as well as performance improvements over the predecessor Maxwell. Here is what we know about Nvidia Pascal architecture so far.
Nvidia Pascal Specifications:
- Pascal graphics architecture
- 2x performance per watt estimated improvement over Maxwell
- To launch in 2016, purportedly the second half of the year
- DirectX 12 feature level 12_1 or higher
- Successor to the GM200 GPU found in the GTX Titan X and GTX 980 Ti
- Built on the 16nm FinFET manufacturing process from TSMC
- Allegedly has a total of 17 billion transistors, more than twice that of GM200
- Will feature four 4-Hi HBM2 stacks, for a total of 16GB of VRAM and 8-Hi stacks for up to 32GB for the professional compute SKUs
- Features a 4096-bit memory bus interface, same as AMD’s Fiji GPU power the Fury series
- Features NVLink (only compatible with next generation IBM PowerPC server processors)
- Supports half precision FP16 compute at twice the rate of full precision FP32
As for the pricing, the Nvidia Pascal cards are rumored to cost between $600 to $1,100. The chip maker is planning to launch the new GPUs at Computex 2016 in May.
