Back in 2011, Nvidia announced to the world that they had acquired a license for the latest ARM instruction set, the ARM v8. But the most exciting part of the deal was that the new ARM instruction set is 64-bit. After making 32-bit mobile CPUs, Nvidia was set to take their Tegra K1 platform to the next level with a 64-bit mobile CPU. At the Hot Chips conference this year, Nvidia revealed their little project that they have been quietly working in for all these year. The Tegra K1 ARM v8 64-bit chip from Nvidia is ready for a release later next year. The new chip is codenamed Project Denver.
The upcoming chip is a 192 core Kepler class chip which is the basis of Nvidia’s previous 32
-bit Tegra K1 mobile CPUs. Being from the same class, the newer chip will have the same pin configuration and compatibility with the previous generation of Tegra, thus making the implementations of this chip much more cost effective. The new chip will pair two Denver Chips on one die. According to Nvidia, pairing two processing cores for their upcoming chip provided them with a far higher performance when compared to the quad or octa core mobile processor designs from rival companies.
Each of the Denver chips can attain speeds as high as 2.5 GHz. The newer chips have a 7 way superscalar microarchitecture, in contrast to the 3 way of the previous generation. What this means is that the chips will be able to execute up to 7 concurrent micro operations per clock. The mobile CPU also comes with a 128KB 4-way L1 instruction cache, a 64KB 4-way L1 data cache, and a 2MB 16-way L2 cache.
Nvidia also confirmed that they are indeed working on Android L’s support for 64-bit processors on their Denver chips. According to Nvidia, consumers can expect devices packing the new chip to be available by the year’s end. If they do pull it off, Project Denver will definitely bring mobile CPU at par with desktop processing prowess. That and the fact that with the latest OpenGL 4.5 and Android Expansion Pack, we can expect graphical features like tessellation on Android L, the next version of Android looks better by the day!
