#2 The HP Elitebook 745 G3 (Carrizo, PRO A12-8800B)

The Carrizo Elitebook 745 G3 looks practically identical to the Kaveri based 745 G2, so there’s no need to cover the visuals again, but the internals here cause a lot of talking points.

The G3 is almost the top premium model Carrizo you can buy, coming in at nearly $1100 if you put up the cash for the top model, which includes as much memory and storage you can fit in. For our unit, it came in at a more modest $700 ($700 for the base model, this was more $1100), which is more in-line with what price point AMD originally expected the Carrizo platform to hit. This is the first notebook with AMD’s new A12 line of processors, with this one being the PRO A12-8800B. This is a 15W part running at a base frequency of 2.1 GHz with a turbo mode up to 3.4 GHz. Any mobile APU in the A12 category has a full complement of 512 streaming processors similar to the FX mobile parts or A10 desktop parts, and the A12 runs these at 800 MHz. Unfortunately this is slightly crippled by only having the equivalent of one memory module in play, a single 4GB DDR3L-1600 module. It is dual channel capable if another is installed.

One of the big plus points with this model is the display, in comparison to the dire one on the G2, but this probably explains the majority of the cost in this 745 G3. With a 2560x1440 IPS display running a high contrast ratio (1422), it did have the best display out of what we tested for this piece. This is matched by the Wi-Fi solution, which had Broadcom’s BCM943228Z module which is an 802.11ac module in the M.2 form factor. One of the general feelings I had from the engineers here is that laptop Wi-Fi will all migrate to M.2 eventually on the understanding of better power control and form factor.

G3 Specific Testing

The 2560x1440 display varied from 0.21 nits all the way up to 297, nearly reaching the 300 mark but resulting in a 1422 contrast ratio. The white point was high, marking it up at 6657K.

While the color accuracy calibration graph looks as if the red line is the one going off on its own, it is actually the red line that is most accurate – we’re expecting a straight line through (0,0), (32,32), (64,64) and so on and while the red line is below most of these points, it isn’t as low as the green or blue.

The CPU-Z outlay shows the new FP4 socket with Carrizo over Kaveri, as well as having the full 12 compute units with those 512 SPs in tow.

On the integrated graphics side, despite the R7 graphics in there, the important element is that memory bandwidth running at 12.8 GB/s due to the single channel memory in use. We can also see the GPU clock running at 200 MHz idle, lower than the Kaveri implementation, which has power benefits.

With the 745 G3 we were able to do a run down on our light battery test, as well as run through some charge numbers.

    Holy shit, I haven't seen that many pages in a long time. You don't see this much content very often. Gotta love dat chorizo.

    ImSpartanus, they're just writing a comprehensive article. I'm sure they put in good work with all of them.

    I think this article provides a pretty delicate and nuanced treatment of chorizo and its place in the market (both potential & actual). There's no doubt that the circumstances demanded it. This was not business as usual and I'm glad Anandtech recognized the need for that additional effort.

    We're fooling ourselves if we pretend that any journalistic entity puts the sane amount of effort into every project. We're talking about living, breathing humans, not robots.

    I found the language convoluted, verbose, and difficult to read, compared to, say, Anand's straightforward and logical writing:

    "Nonetheless, Intel’s product line is a sequence of parts that intersect each other, with low end models equipped with dual core Pentiums and Celerons, stretching into some i3 and i5 territory while still south of $1000. In this mix is Core M, Intel’s 4.5W premium dual core parts found in devices north of $600."

    "south of/north of"... can't you just put in "below/above"? And all that "intersecting of parts", can't you just say from the Atom to Pentiums, Celerons, i3's, and i5's....

    The whole thing reads like they're paying you to score a high word count. Lots of information to extract here, but it can be 3 pages shorter and take half as long to read.

    That is why Anandtech has video adds on their main page - designed for people like you. Who simply lack reading comprehension past 8th grade and find it hard to understand. Just watch watch the video on how to loose weight that auto-plays on the side.

    Or... try Tom's Hardware - they cater to your demographic.

    There's no question that Anand had a powerful way of writing that was uniquely simple yet educated you nevertheless. And for a layman that reads this sort of stuff to learn new information, that's very attractive and I kinda miss it (along with Klug).

    However, I give Ian a pass because he at least attempted to use other brand of conveying his ideas. In certain sections he used special table-like fitting to separate "parallel" sections/stances so that the rader would be more apt to compare them. So there's at least some effort, though he surely could do better.

    fmcjw does have a point, but in all fairness it is much harder to explain techical stuff in layman terms than it is to be long-wordy. Carl Sagan was the master of it on TV, and Anand was excellent at it on paper.
  • JMC2000 - Sunday, February 7, 2016 - link

    I didn't find anything wrong with the language Ian used, as this is piece is still on a technical level, but can be understood by the layman that knows a bit more than just what the stickers on the outside tell.

    To me, the phrase "parts that intersect each other" lays out that there is a myriad of options where configurations overlap, where as saying "from the Atom to Pentiums, Celerons, i3s and i5s" indicates that there is a pricing structure that is related to general CPU performance, which there really isn't when it comes to low-end machines.
  • plonk420 - Monday, February 8, 2016 - link

    "south of/north of" sounds better than "greater than/less than," which is more correct than "below/above"
  • Sushisamurai - Thursday, February 11, 2016 - link

    yeah, colorful language is nice. Dumbing down adjectives or descriptions can often construe the true message IMO. This way, it paints a more descriptive/colorful picture.

    Keep up the good work Ian.
