    $AMD's answer to $INTC Silvermont? Pray.

    • Justin Jaynes: Let's wait until we see power consumption before we start popping champagne =p again - The 15W Kabini doesn't consume *close* to 15W cinbnch

    • Justin Jaynes: http://bit.ly/17tY7MH it consumes probably between 4.5 to 6.5W - Anand didn't isolate just the SoC in these measurements

    • Ashraf Eassa: Yeah, but good luck fighting ~2 generations of process tech + Intel's massive R&D might. Intel is about to drop a nuke on AMD + ARM vendors
      9/6/13
    • Justin Jaynes: Maybe according to PR and selected benchmarks? My guess is that Intel is very good about managing power consumption between the CPU and GPU

    • Justin Jaynes: let's see some real world benchmarks like some games that tax both, or some video playback (typical tablet usage)

    • Justin Jaynes: The 15W Kabini you're making fun of only uses 1W when surfing the web or just over 1.5W when watching 720p video.

    • Justin Jaynes: http://bit.ly/1enNiSJ first hands on bay trail tablet reports stuttering issues already, possibly due to driver issues
      9/6/13
    • Justin Jaynes: i've written before that Intel's GPU is pretty inefficient - do you argue this point? And the GPU in Bay Trail is 4EUs clocked slower than

    • Justin Jaynes: their desktop parts - so less than 1/3 of the HD3000 performance. How many people do you think use tablets for CPU intensive tasks
      9/6/13
    • Justin Jaynes: compared to tasks that utilize the GPU? I don't see a lot of people looking at their tabs thinking about how great it runs cinebench :-p

    • Ashraf Eassa: I love how nobody believes Intel marketing slides, but they're usually pretty accurate. Haswell rocked - as promised.
      9/6/13
    • Justin Jaynes: I'm not denying Intel's marketing slides about CPU performance, or even GPU performance - but physics are physics

    • Justin Jaynes: Intel's GPU EUs consume more power than AMD's GCN cores and take up more die space when doing so based on some rough estimating
      9/6/13
    • Justin Jaynes: Again, I bet Intel has some pretty good control of where it sends power - ie CPU or GPU depending on load, but if you tax both CPU and GPU

    • Justin Jaynes: but don't raise that tiny 2W power envelope, something is going to be starving for more electrons
      9/6/13
    • Justin Jaynes: the biggest unknown regarding bay trail are the silvermont based CPU cores - we have a rough idea of how the EUs behave
      9/6/13
    • Justin Jaynes: and the 4.5w to 6.5w power consumption of the A4-5000 doesn't take into account inefficiencies in the voltage regulator

    • stockalicious: " Haswell rocked - as promised." Rocked what? ive read some of the reviews and the word "Rocked" was never used
      9/7/13
    • Ashraf Eassa: The MacBook Air's battery life (thanks to Haswell) has been very highly praised.
      9/7/13
    • Justin Jaynes: Haswell's battery life is the only real thing I've seen praised. Anything less than Iris Pro GPU wise has been luke warm at best
      9/7/13
    • Justin Jaynes: And almost every single review I've seen for desktop haswell has been a yawn.
      9/7/13
    • Justin Jaynes: I specifically call out the GPU because Intel's PR slides hyped up the GPU, but if you look a lot of it is based on Iris Pro
      9/7/13
    • Justin Jaynes: Out of curiosity have you seen any of the 28W mobile parts yet with 40 EUs and the higher TDP?
