Nvidia announces next-gen Tegra K1 chip, features 192-core Kepler GPU

by: Andrew GrushJanuary 6, 2014


At tonight’s CES press event, Nvidia announced their next-gen Tegra processor, the Tegra K1. The Tegra K1 is a substantial upgrade from the Tegra 4, particularly when it comes to graphics prowess.

The new K1 chip comes in two pin-to-pin compatible versions. The first is a 32-bit quad-core chip with a 4-plus-1 ARM Cortex A15 CPU, and the second is a custom Nvidia-designed 64-bit ‘Denver’ dual “super core” CPU that is based on the ARMv8 architecture. Both versions of the chip feature the same impressive 192-core Kepler GPU, delivering what Nvidia claims will bring “next-gen console gaming graphics” to mobile devices.

While we have yet to really get our hands on the Tegra K1 to give it a true run for its money, we can say that it looks to pack a pretty hefty punch. Furthermore, it will work with Epic’s Unreal engine 4 and will have support for both Direct X11 and OpenGL 4.4 technologies. According to Nvidia, the Tegra K1 not only has tons of power but it is also an efficient chip that the company says is roughly “1.5 times more efficient than other mobile GPUs”.


Now the big question is when we’ll actually see the Nvidia Tegra K1 arrive to mobile devices. Reportedly the first device’s based on the 32-bit chip should be arriving sometime in the first half of 2014 — so pretty much right away. As for the 64-bit chip, it won’t actually make its way into the market until the second half of the year.


The Nvidia Tegra K1 is certainly a major step up for the company, but will the chip be able to compete in a bigger way than the Tegra 4? Only time will tell for sure. Be sure to stay tuned to CES where we’ll be bringing you demos and other news related to K1 over the course of the next few days!

… developing … stay tuned!

    Snapdragon 805 vs Nvidia Tegra K1, let’s see if Nvidia can pull it off this time

    • Thomas Su

      They will.

    • DrewNusser

      Sure looks like it. We’ll see how true the claims are, I guess.

    • TjaldidTjaldid

      VS the 805 probably… however I have a feeling that they will announce several new chips that will come out through the entire year so I don’t expect the 805 to be the flagship.

    • najiy91

      price comparison?

    • Shark Bait

      I hope so , tegra has always been great but always lacked something, like LTE , let’s hope this will become mainstream and give Qualcomm some competition!! If only it wasn’t 28mn …

    • apianist16

      I doubt it, though I would like to see Tegra succeed. I seems to me that nVidia generally overpromises and underdelivers with their mobile chips. I think that they just lack the experience of Qualcomm.

    Hmm. I wonder if this will be in the Surface Mini, then.

  • najiy91

    snap d 805 vs tegra k1 price comparison?

    • paul neal

      If the tegra comes out later in the year, say around July, quallcom will have something to compete, but the 805 will be no match in the graphics department

    Their website says it’s 28 nm, how do you pack 192 GPU cores in, without going to 14nm, this years PPI means UD 4k in 7″.

    • Jusephe

      Simply said, that chip is big… Big chip with lost of GPU units… See how tiny those cortex A 15 cores are ? (Yellow squares)

      Nvidia say what you want but a huge chip with 192 Kepler units is not going to be a long runner on battery especially when playing games.. Only word about how much more performance it has wasn’t said like at tegra 4 launch- 6x the performance. Only how it supports unreal engine 4 and other things…
      And what about efficiency ??? 1.5 x compared to what ? I heavily doubdt it is compared for example rouge which is not only the most efficient GPU architecture in mobile but propably the most efficient GPU architecture to date.

      This is just typical Nvidia marketing and when it comes to actual chip… Well we will see.

      • stucrmnx120fshwf

        Yes, I am thinking It would have to be 14 nm, to not eat the battery alive at UD 4k. My 28 nm AMD video card, needs a fan to keep it cool.

      • hahmed330

        Big chip doesn’t mean higher power consumption… You clock the 192 cores way down at per say 200mhz the power consumption will be much lower then clocking 96 cores at 400mhz… Even though both would have equal amount of performance. Get your facts right please

      • me

        It is well known, maybe not so well known, that nvidia photoshops the “die” shots they show. They are just representative of what they want to highlight on the chip

  • mr

    omg great now a mobile phone gpu has officially more cores than my laptop…
    (GT 630m 96 Cuda cores vs Tegra K1 ULP Geforce 192 Cores)

    • MasterMuffin

      Well 630m is a low end GPU. GTX 680 has over 1500 :)

    • Ichibanmugen

      most likely this is meant for tablets..

  • George

    Too bad no one plays with nvidia anymore. :P

  • Bone

    Tegra 7: 100000000000000000000000000000 GPU cores

    • t3chb0y

      That’s just too many. Way too many.
