Nvidia Pascal
Tijekom današnjeg uvodnog govora na GPU tehnološkoj konferenciji u San Joseu, Nvidia je predstavila novi roadmap budućih procesora. Predstavili su Pascal, obitelj GPU-a koja će naslijediti ovogodišnje Maxwell GPU-e. Imenovana po francuskom matematičaru iz 17. stoljeću, Blaise Pascalu, sljedeća generacija GPU-a će donijeti nekoliko novih ključnih karakteristika kao što su: stacked DRAM, unified memory i NVLink.
Pascal dolazi 2016. godine sa sljedećim karakteristikama:
- 3D Memory: Stacks DRAM chips into dense modules with wide interfaces, and brings them inside the same package as the GPU. This lets GPUs get data from memory more quickly – boosting throughput and efficiency – allowing us to build more compact GPUs that put more power into smaller devices. The result: several times greater bandwidth, more than twice the memory capacity and quadrupled energy efficiency.
- Unified Memory: This will make building applications that take advantage of what both GPUs and CPUs can do quicker and easier by allowing the CPU to access the GPU’s memory, and the GPU to access the CPU’s memory, so developers don’t have to allocate resources between the two.
- NVLink: Today’s computers are constrained by the speed at which data can move between the CPU and GPU. NVLink puts a fatter pipe between the CPU and GPU, allowing data to flow at more than 80GB per second, compared to the 16GB per second available now.
- Pascal Module: NVIDIA has designed a module to house Pascal GPUs with NVLink. At one-third the size of the standard boards used today, they’ll put the power of GPUs into more compact form factors than ever before.
