NVIDIA Introduces Denver 64-Bit Tegra K1 Processor

    NVIDIA introduced the new Tegra K1 processor in January, there was a corresponding publication on Habré . Then it was known about the 32-bit four-core Cortex-A15 processor. It was also said that a 64-bit processor with two Denver cores of its own design from NVIDIA will be released.

    Yesterday, the company’s blog posted more detailed information about the second type of chip; we can say that the official presentation of this processor took place.

    Unfortunately, the exact timing of this chip is not called, but the characteristics of the processor are still presented. So, the 64-bit version of Tegra K-1 is “sharpened” for working with the new Android L OS (the developers claim that the performance of the dual-core Tegra K-1 processor is higher than that of the “mobile” four and eight-core processors). At the same time, both versions of the processor have compatible pads, so motherboards do not require rework.

    Tegra K-1 with Denver are intended primarily for working with “heavy” applications, including toys, as well as with no less “heavy” media content.

    As for the two Denver cores, the 192 KEPler graphics CUDA cores are added to them, which allows you to process seven instructions in one clock cycle, as well as save the most frequently used sections of program code in a 128 MB buffer. This process is called Dynamic Code Optimization. Each of the two cores includes 128 KB of 4-way L1 instruction cache, 64 KB of 4-way L1 data cache, and 2 MB of 16-way L2 cache.

    According to the developers, 64-bit processors are very energy efficient, the chips work using dynamic changes in both frequency and voltage. The developers also argue that such processors are comparable in performance with the Apple A7 or Celeron 2955U / Haswell.

    Devices based on 64-bit Tegra K1 will be released this year, however, the release date of such devices and their description are not provided.
