Nvidia kicked off GDC 2014 with a few new announcements in the GPU market. First, Jen-Hsun Huang revealed the reasons why the GPU is not seen as the top piece of kit in the personal computer, due to constraints on memory bandwidth between the CPU and GPU, something Nvidia has apparently fixed with NV Link.
NV Link is a new technology built by Nvidia to increase bandwidth between the CPU and GPU by up to x15, leveraging the PCI-Express standard to make the size of the bandwidth larger, leading to better all round performance on the PC. This is a big leap over PCI-Express 3.0, but is less impressive compared to the new PCIe 4.0.
Still, NV Link has up to six times better performance than the current PCIe 4.0. Nvidia’s solution will be available for chip manufacturers to use, instead of the PCI standard. We are not sure how many PC manufacturers and chip makers will actually choose NV Link, despite its performance advantages.
Nvidia also announced the new GeForce GTX Titan Z, a dual-core GPU for high-end users. This looks to replace the GTX 780 Ti GPU, with up to two times better performance thanks to double precision floating point and double the RAM.
It looks like the next generation GPU, named Pascal, will also be delayed until 2016. The roadmap looked a little difference from the one Nvidia showed last year, with an increased time period between Maxwell in 2014 and Pascal in 2016.
The clock speed for the new Titan Z was not revealed on stage by Nvidia, but we did find out the GPU will have 5.760 cores in total, 12GB of RAM and up to 8TFLOPS of performance. It will also have an increased price, available for $3,000.
