Intel Baytrail vs. NVIDIA Tegra 4: too close to call

September 11, 2013

Intel processor

The NVIDIA Tegra 4 chipset has had some trouble catching on. While the Tegra 4 is snappy, OEMs are favoring the likes of Qualcomm, or making their own chipsets. Intel also looms on the horizon, and recent benchmarking shows their new 22nm chips are primed to keep pace with the Tegra 4.

In Geekbench testing, the Intel Baytrail T chips (byt_t) were nearly identical to the Tegra 4 in single and multi-core scoring. Both ran a variant of Android 4.2 — 4.2.2 for the Intel chip, 4.2.1 for NVIDIA — and similar amounts of memory. The Baytrail T was clocked at an impressive 2.39GHz, whereas the Tegra 4 was checked at a respectable 1.9GHz.

Perhaps the real turning point was multi-core floating point operation, where the Intel chip simply blew the Tegra 4 away. When it came to single-core operation, the Tegra took the edge, but only slightly. The Baytrail chip also outclassed the Tegra 4 in memory processing.

With Qualcomm letting loose the Snapdragon, and Intel announcing Baytrail alongside a slew of new Chromebooks today, Tegra 4 implementation seems highly unlikely at this point. NVIDIA may have the Shield and Tegra Tab to showcase their wares, but other OEMs are simply looking elsewhere.

    empire strikes back. Can’t wait to see performance oriented android devices running Intel

    Baytrail: 2.39 Ghz Andorid: 4.2.2
    nVidia: 1.91 Ghz Android 4.2.1

    What do you guys think?
    Also there’s the question of power consumption.
    What about graphics performance of Baytrail?

    • Pk

      And there’s also the question about heat.
      AND ability + headroom to OC/UV? We love that, don’t we?

    • jfinely

      Do you guys know that the Nvidia Shield has a fan for cooling?
      When energy consumption is figured in, Baytrail running at less than 2.5W will be the clear winner.

        hhh

        The Shield is intended to run 100% all the time (100% duty cycle) so it avoids thermal throttle. Also, it doesn’t dump heat into the user’s hands, while phones and tablets dissipate heat in the casing.

        Baytrail real world power consumption is unknown and any phone or tablet will thermal throttle to reduce heat output to meet TDP. Besides it’s at 22nm, it should be better, but the GPU isn’t really. Nvidia is still using PS3 era GPU (about 7+ years old).

      Check the reviews done by pc perpective. They include gpu test in their review. Honestly i wonder how much tegra 4 can do if they got thesame process node advantage as intel Bay Trail have.

      A few benchmark here: http://www.anandtech.com/show/7314/intel-baytrail-preview-intel-atom-z3770-tested/3

      With regards to power consumption about 2 – 2.5 times better power saving than clover trail (take that with a grain of salt).

      CPU wise it easily one of the best in class.

      GPU wise a modified Intel HD4000 integrated graphics (4 EU compared to 16 EU for desktop/laptop) that achieves about 10 -15% better performance over the adreno 320 (snapdragon 600) which is kinda disappointing but more than capable for most games and tasks.

      Considering that the following is in ‘pre beta’ for android 4.2.2 obviously (hopefully) the final product will improve on that.

      So pretty good news for X86 front anyway.

      Graphic are HD4000 and should be competitive. The notebook HD4000 outperforms the best SOC’s to date. However, my guess is that the move to a lower clock and TDP will certainly take their toll.

  • Jack Parker

    If nVidia are keeping up with 500mhz less per core, Kudos to them for making a great processor

    • Pk

      Agreed.

  • Caitlin Bestler

    As benchmarks go, isn’t Geekbench almost the opposite of Antutu? As I scan the Geekbench tests I’m not seeing much where the Tegra 4’s GPU cores would help. While the Antutu tests are if anything overweighted to thinks the GPU handles.

  • p3ngwin

    now how much will Intel sell those chips?

    Intel are notorious for demanding a premium on their processors, usually 2x or even 3x the price of ARM chips.

    • APai

      yeah, the last thing we want is an intel monopoly even on tablets and phones. once you let them in they squash the opposition with every dirty trick in the book. they are are pretty much like microsoft

  • Magnetic1

    Every phone and tablet and netbook and laptop with intel cost more than something without intel. I’m just saying with all of the other things being equal or pretty close, I’ll pick the best value proposition. And not to mention they both don’t do 64 bits, how so yesterday technology.

    • kevgr5

      64 bit means nothing today , when phones come with more than 4gb ram and software is coded to take advantage that may change, but by then android chips will all be 64bit!

    • vangard

      Baytrail is 64-bit.

  • instanick

    I prefer Apple 64-bit A7 processor :)

    /s

    • Humaan

      A7 is samsung made processor
      64bit arm did no great magic on IOS compared 32bit arms like s800 on android
      Expect better in 64bit android landscape soon.

  • Amir

    I love to see this kind of competition. It would greatly benefit consumer. Lets the fight begin…. Endlessly.

  • George

    Well…if Intel’s SoC has passive cooling instead of nvidia’s shield that uses a fan to keep things cool, kudos to Intel!
    If not, kudos to nvidia then for having lower cpu clock and around the same scores!

  • Balraj

    Got to see how snapdragon 800 processor does against Apple a7
    Specifically in gpu performance…I hope AA does a shoot out with lg g2
    I don’t trust Samsung note 3..it might have been optimised….

    “NVIDIA may have the Shield and Tegra Tab to showcase their wares, but other OEMs are simply looking elsewhere.”

    Looks like the author of the article just crawled out of a cave – HP, Toshiba, Acer, Asustek, Microsoft, and others had announced or will announce T4 tablets. They have more tablet wins then anybody else at this point. These are major players in the Tablet – PC space.

  • deppman

    These numbers look very much exaggerated.

    The top of the line baytrail part is the Atom Z3770. It has a base clock of 1.8Ghz with “bursting”, which is also known as “benchmark mode” or “completely blow your TDP mode” up to 2.4 Ghz. Check out this overview: http://www.pcper.com/reviews/Processors/Intel-Atom-Z3000-Series-Review-Bay-Trail-and-Silvermont-Arrive.

    If the entire run was done using benchmark mode – sorry, “bursting” – the processor almost certainly drew far more than 2.5W. At the stock 1.8ghz, the performance looks quite mediocre – perhaps 75% of the T4. Its really a shame too, given Intel’s fab advantage (22nm vs 28nm). Imagine a T4 at 22nm with a 2.4Ghz base clock!

    I don’t know why Intel just doesn’t buy Nvidia already. A 14nm T5 would be insanely good.

  • Dr.Mefityiszto

    NVIDIA SHIELD has a heatsink AND a fan for a reason. Obviously it consumes more power than a fanless baytrail tablet. In this market any comparison without measured power (or at least battery life/battery size) is meaningless.

  • Francis Short Jr

    Intel same amount speed as snapdragon 800 If more energy efficient would give competition

  • Jaroslav Jandek

    You do realize, that the tested reference tablet had an alpha version of Android that had serious issues with multi-threading, right? Intel is still tuning the Android VM (Dalvik) so it’s like it was operating only on two cores (out of four).

    The Bay Trail is a beast, especially in int and float calculations, but the graphics performance is mediocre. Overall it is an excellent SoC with 2W SDP.
    Also, Tegra 4 is actively cooled, which means that it is operating at its maximum performance. Tablet and smartphone maufacturers aren’t going to use active cooling.

  • CpuKnight

    But the graphics chip on the Baytrail is pretty bad actually. Better than the PowerVR chips they used to use no doubt but still not competitive with the Adreno 320 and Tegra ULP
