PCMark 08
PCMark08, developed by Futuremark, is a simple press play and run benchmarking tool designed to probe how well systems cope with a variety of standard tasks that a professional user might encounter. This includes video conferencing with multiple streams, image/file manipulation, video processing, 3D modelling and other tools. In this case we take the three main benchmark sets, Creative, Home and Work, and run them in OpenCL mode which aims to take advantage of OpenCL accelerated hardware. For fun we also put in the PCMark08 Storage workset.
Both of the Home and Work tests show something starteling in the Kaveri system beating all the 15W Carrizo parts. This comes back to what we saw on WebXPRT on the last page – these workloads are very bursty in nature, requiring the system to wake up, run a small amount of work, and go back to sleep. It would seem that this requires a lot more effort from the Carrizo platforms than the Kaveri ones (perhaps by nature of the lower idle power draw starting point on Carrizo) which impacts time critical performance metrics.
If we take the CPU frequencies of the two Elitebook systems, starting with the 745 G2 (Kaveri)
Here the standard frequency tends to be in the 3300 MHz region, moving down to lower frequencies when more threads are needed. But for the 745 G3 (Carrizo):
Here the CPU frequency is obviously mostly at the 2500 MHz mark, sometimes bursting up to 3400 MHz (It’s actually more of a 2:1 split in favor of 2500 MHz).
You might argue that the temperature of the design might be to blame. Both Elitebooks are in the same chassis, so let us see:
(take note of the scales)
Here it shows the G2 wanting to stay below 60C, whereas the G3 is happy to go almost to 80C, albeit with an average temperature which is nearer 50C. This means that the G2 can arguably keep the higher frequencies for longer.
Just to weigh in on the other 15W Carrizo designs in the Toshiba Satellite and HP Pavilion:
In both cases, similar to the G3, the main frequency for the test is actually the lower 2500/2300 frequency, with the system moving up to the higher frequency state around a third of the time, rather than staying at the higher state and moving back down. This is what is causing the Kaveri system to win out in these sorts of workloads (though likely at a power penalty).
On the storage front, having a mechanical drive is a killer here.
Agisoft Photoscan
Photoscan is professional software that takes a series of 2D images (as little as 50, usually 250+) and 'performs calculations' to determine where the pictures were taken and if it can create a 3D model and textures of what the images are of. This model can then be exported to other software for touch-ups or implementation in physics engines/games or, as the reader that directed me to it, national archiving. The tool has four phases, one of which can be OpenCL accelerated, while the other three are a mix of single thread and variable thread workloads. We ran the tool in CPU only and OpenCL modes.
When pure CPU performance matters, having the higher thermal headroom matters most. But moving it to the OpenCL mode shows that those extra TDP points can matter a lot on load balancing:
There are two things to note here. One, something seems to have gone very wrong with the G3, and I’m sure those numbers are erroneous and need to be re-run or the 4GB of memory is actually a hindrance here. The second is that the combination R7/R9 graphics in the Lenovo, despite not being in Crossfire, can both be used in OpenCL mode. This pushes a speed up of almost 30%.
Linux Bench
Linux Bench is a collection of Linux based benchmarks compiled together by ServeTheHome. The idea for this is to have some non-windows based tools that are easy enough to run with a USB key, an internet connection and three lines of code in a terminal. The tests in Linux Bench include standard synthetic compute, compression, matrix manipulation, database tools and key-value storage.
Unfortunately Linux Bench refused to run on any of the HP systems for relatively unknown reasons – the fact that it was all the HP models perhaps means that there is something firmware related which is causing the LiveCD to not boot properly. Nonetheless, the results are here for completeness.

no A12 core parts for the test? I can't find the A10 part on the HP websiote, only A8 & A12UtilityMax - Wednesday, February 10, 2016 - link
After a decade of hype since the ATI acquisition, nothing has changed. AMD has a massive OEM problem. Moreover, laptops have been outselling desktops for like a decade, yet AMD if you look at the history of AMD, it's hard to believe they ever really cared about portables. The Kaveri parts didn't even show up, while the Carrizo notebooks are already botched technology as explained in the article..gserli - Thursday, February 11, 2016 - link
I have to say that the $400 to $700 notebooks on sale are garbage.The IGPs are not strong enough for casual gaming like LOL and CS GO.
Crappy 5400RPM harddisk will make you want to throw the machine out of the window.
If you really need that little bit more performance.
Pay few hundred more. Or you can get a notebook that will hurt your arm if you carry it with one hand.
AMD needs to be more aggressive. Talk to the OEMs and give them better offer.
Convince them build a $700 notebook with 13 Inch 1080p IPS touch screen, 256GB SSD, 8GB RAM, A8 or A6 APU and below 1.5KG.
A lower end $600 one would work with 1366*768 IPS touch screen, 128GB SSD, 4GB RAM and A6 APU, below 1.5KG.
My $640 Asus TP300L is absolutely bullshit! I thought a mobile i5 would be enough for my daily use since I had a i5 desktop and was really satisfied with it.
CPU performance is not a issue nowadays. The IGP is slow, but I didn't expect it to be fast(Although the one on desktop is way more powerful).
The biggest problem is the GOD DAMN 5400RPM HARD DISK.
Not only did it affect the boot up speed. Every action I performed is awfully slow when there are some OS things running in background.
Only if I wait for 5 or 10 minutes after boot-up, then I can use it normally.
Please, kill all the 5400RPM Hard disk. They should not be in 2016.

That's what I find so hilarious about all the Y700 6700hq lovers out there - all the CPU power in the world is relegated to potato status outside of b.s. benchmarks with that 5400rpm HDD. Save money with the FX8800p Y700 and buy an $80 250GB Samsung 850 Evo to slap in it...wow&wow - Thursday, February 11, 2016 - link
Will it be more appropriate to have "Additional" (Why not Update?) in the beginning, particularly the misleading pre-production stuff? Thanks for the article.farmergann - Thursday, February 11, 2016 - link
LOL, because the entire point of this article would be nullified. They didn't even bother comparing the FX8800p Y700 with the intels head to head outside of some DX9 garbage. Pitiful anandtech shills are pitiful. How many times did they mention Freesync? Yeah...silverblue - Friday, February 12, 2016 - link
To be fair, is there a point?xrror - Thursday, February 11, 2016 - link
"Some companies in the past have dealt with contra-revenue, selling processors at below cost or with deals on multiple parts when purchased together. Very few companies, typically ones with large market shares in other areas, have access to this. Some members of the industry also see it as not fighting fair, compared to actually just pricing the parts lower in the first place."I had to laugh so much as this. WHO COULD IT BE? MYSTERY!
It must be... Cyrix ! no? hrm. I give up. =P

still ... there is just no saving the bulldozer architecture, no matter how much they improve or iterate it.bulldozer and amd by proxy for normal users are synonyms for "just not as good as intel" and for a little more experienced users "that processor that cheated with its core count".
the few people who actually read articles like the one above and compare performance/value represent literally no market share.
the only way out for amd at this point is to create as much boom around their zen-cores as possible, get them out asap, hitch their little start to new buzzwords like hbm, old buzzwords like rage and hope they can actually deliver the performance figures needed in the first reviews to drive a wave of positive articles through the press. only then will they be able to get back into the market. i wish them the best, a surface 5 (non pro) with a low power zen apu on hbm sounds awsome ... i'd get one of those in a heartbeat.

I own a Toshiba P50D-C-104. I read with interest this article and, albeit extremely helpful and rich of information, left some questions open, at least as far a I'm concerned.First of all, the P50D-C-104 costs <$600 and has an A10-8700P. I find this price range more relevant for home-users and, in general, for somebody interested in AMD offering.
1Kusd for a laptop with integrated GPU seems too expensive.
The P50D-C-104 has 2 DIMM slots; couldn't find for sure whether it is dual channel or not.
I am curios to know how it performs on some popular games against Intel's offering (at that price level, it would go against core i3, at best). In the page with comparison against Intel's offering there are almost only synthetic benchmarks: it would have been nice to compare on some actual games.
My point is that in the $1K range, there are many features that could add cost while not necessarily improving performance.
