#1: The HP Elitebook 745 G2 (Kaveri, A10 PRO-7350B)

The Kaveri system chosen was selected as a pinnacle system – one of the best 19W Kaveri devices currently on sale. This is an A10 PRO-7350B system, which translates as a dual module/quad thread processor with a base frequency of 2.1 GHz and a turbo mode up to 3.3 GHz. The APU contains integrated ‘R6’ level graphics based on GCN 1.1, for 384 streaming processors at a frequency of 533 MHz. The 1600x900 TN display was certainly nothing to write home about, but unlike some other devices in this test it came with a 256GB SSD and is strangely enough the only device in our test with dual channel memory (2x4GB, DDR3-1600 C11). This memory aspect is one we’re going to revisit a fair bit as it explains a significant angle surrounding the binary decisions that AMD has to make in a platform.

The Wi-Fi on hand in the G2 was a single stream Broadcom 802.11n solution, which is broadly disappointing. A remark I will probably make several times in this piece is that if I can get 2x2 802.11ac on a sub-$150 motherboard, why is it not in a laptop >$600? A positive on the battery life side is that the G2 had the biggest battery out of all the devices we tested, coming in at 50.274 Wh, although unfortunately our battery life test failed and we ran out of time to run another.

As for the device itself, the HP Elitebook line is typically focused on premium business customers, and comes in as one of the more stylish elements this field, relying on an aluminium clamshell and a polished design to set the tone. HP is one of AMD’s top tier partners for laptops, which is in itself somewhat surprising perhaps, but most of their business is in the professional line. This means features such as a VGA port and a fingerprint sensor come standard.

It certainly does not look out of place in any meeting room or on a flight. The bezel around the display is noticeable but not too large, with a 720p webcam at the top.

On the sides we get a total of four USB 3.0 ports, and a DisplayPort to compliment the VGA. To fit with some business use, the smart card reader is on the left, as well as the docking port on the right hand side between the circular power cable and the Ethernet port. The Ethernet port is interesting, given that in the ‘thin is best’ mantra for laptops an Ethernet port is quite bulky, so many devices eschew them all together and provide a USB-to-Ethernet adaptor. But instead we have an expanding Ethernet port which makes room for the RJ-45 connector. It saves having to remember another cable in the work bag.

Mouse movement comes from both a trackpad and a nub in the center of the keyboard, with each having a mix and match set of left and right mouse buttons. Personally, using the trackpad during testing was a nightmare as it was not particularly responsive, requiring exertion and exaggeration to get the cursor to move, meaning for most of the time a mouse was plugged in anyway. Technically this G2 sample is actually an old one from stock, perhaps suggesting it has been ‘lightly used’. This is shown by the front of the device.

Even a bad camera can’t hide some scratches. Then again, a number of business devices are held in pouches to save from scrapes, perhaps belying the ‘we kept this in a stack of other laptops that could scratch it’ mantra.

The keyboard was a little different to what I am used to, with odd half-height up and down arrows as well as having the home/end and page up/down keys on the right hand side. There are a couple of immediate second function keys, including the Wi-Fi and Mute buttons on the top right next to the speaker (and also right next to the delete key). The power button on the top left is near the escape key, and in a week I hit it at least twice by accident.

The full aluminium design of the clamshell bodes well for cooling, although there is only a single vent on the left hand side for an exhaust. Depending on the power of the fan, and corresponding heat soak, performance may be temperature affected in the long run.

HP Elitebook 745 G2 Specific Testing

With i1Display Pro colorimeter on hand (sorry, we didn’t have a spectrophotometer for more accurate color measurements), the G2 display running at 1600x900 with a TN panel came very low on our scoring. The high brightness was low (267 nits), and the low brightness was high (1.69 nits), giving an overall contrast ratio of 157. On the plus side, one could argue that the white point, at 6476K, was pretty good.

The color displacement in the calibrated display showed blue was way, way off what it should have been. Both red and green at low settings were also off target, with green having the best default line.

Here is the A10 PRO APU, showing the 19W TDP in the Bald Eagle platform. Kaveri and Carrizo are still both on 28nm, and it’s worth noting that these chips do not have any L3 cache but a super-associative 16-way L2 cache to reduce cache misses.

The G2 graphics are integrated into the APU, showing here the link to DDR3 memory at 25.6 GB/s (that’s dual channel, DDR3-1600 C11) for 384 streaming processors. This falls under the Spectre code name, and is DX12_0 compatible with the right OS and drivers.

    You'd think someone was paying the OEMs to hamstring these machines...

    Some odd facepalm design decisions there.

    Somebody *IS* paying OEMs to hamstring the machines: Customers. Customers who want cheap products that is.

    AMD makes its reputation as: "Intel is too expensive! We're cheap!" Don't act all shocked and surprised when the rest of the components in the system end up being the cheap components too.

    As Anand just pointed out with that price comparison, even with all the cheaping out you can still see a whopping $8 price advantage for AMD on comparably configured notebooks.

    Seriously, some weird stuff. No dual graphics when the chips are almost the same performance? Single channel RAM? What the hell. Reply

    I feel like AMD needs to pull a MS surface or Nexus and put out a reference model to show OEMs how it is supposed to be done. If all OEMs will do is put out a half assed effort, at least then they can just copy the reference design and it will work well. Reply

    +1... You're right, OEMs have pissed off MS and Google enough for them to go solo. AMD could totally follow suit Reply
  • InquisitorDavid - Friday, February 5, 2016 - link

    Sure, if they had the money to. As it stands, the company is now banking on Zen to rescue them. I don't think they can afford to invest in going solo with device designs, at least not right now. Reply

    They could team up with the likes of MSI or Clevo. Both have done good AMD laptops in the past.

    A 14 inch msi laptop with a 100wh battery, a 8800p, and 8gb dual channel ram would fetch a good price from those who want AMD laptops.

    GCN 1.0 in the text and then 1.1 in the grid.
    Nice read BTW.

    Fixed! Thanks :) Reply

    Great write-up, Ian. This is enlightening, and the buoyant attitude at AMD might be saying a lot about what we can expect to see from the 2016/17 product releases.

    Speaking to Carrizo, I'm not sure they realized how badly they were hurting themselves when they elected to keep Kabini/Temash as single-channel designs and then provide OEMs a cheap out by making it pin-compatible with the big architecture. GCN has always been very bandwidth-dependent in every APU they've released. These single-channel setups have got to be really starving the SoC.

    Either way, the performance picture points out what everyone already knows. Zen can't get to mobile quickly enough.
