Who Controls the User Experience? AMD’s Carrizo Thoroughly Tested
by Ian Cutress on February 4, 2016 8:00 AM ESTGaming Benchmarks: 3DMark and Rocket League
Due to timing we were only able to run a couple of gaming tests, namely parts of the 3DMark suite and our Rocket League test. A reminder of our systems, including their graphics:
System Overview | ||||
µArch | APU + GPU | Memory | Channel | |
HP Elitebook 745 G2 | Kaveri | A10 PRO-7350B (19W) R6, 384 SPs, 533 MHz |
8 GB | Dual |
HP Elitebook 745 G3 | Carrizo | PRO A12-8800B (15W) R7, 512 SPs, 800 MHz |
4 GB | Single |
Toshiba Satellite E45DW-C4210 |
Carrizo | FX-8800P (15W) R7, 512 SPs, 800 MHz |
8 GB | Single |
HP Pavilion 17z-g100 |
Carrizo | A10-8700P (15W) R6, 384 SPs, 800 MHz |
8 GB | Single |
Lenovo Y700 | Carrizo | FX-8800P (15W) R7, 512 SPs, 800 MHz R9 385MX, 512 SPs, 900-100 MHz |
16 GB | Single |
One of the biggest issues we’ll see here is the effect of dual channel memory on gaming. The Kaveri system used has a chipset solution that supports dual graphics, but also two memory modules installed. The Carrizo systems either came pre-prepared with one module installed or do not support dual channel memory full stop. This latter point is the main kick in the teeth, especially for a company like AMD that prides itself on gaming – the issue here is down to pin compatibility between Carrizo and Carrizo-L. As the latter only supports single channel, an OEM will design one motherboard to support both platforms (whether they are used for both or not). If a motherboard supports Carrizo-L, then it will not ever support dual channel memory, and any Carrizo APU that is used will be crippled.
Technically the Lenovo Y700 gets around this (hands up if you ever see a Carrizo-L based Y700 please) by equipping the system with a discrete graphics card and disabling Crossfire, so this system will still ultimately win in our tests due to the discrete card. The downside of this augmentation is the higher power draw, which would matter if our Y700 sample had a battery (the retail units come with a 60 Wh battery).
3DMark
3DMark is Futuremark's premium software, developed to tax systems at various different performance levels. The software contains several benchmarks as a result, with some focusing more on smartphone use all the way up to 4K, quad-SLI systems with as many in-game and post processing effects as you can throw at it. The base test, Ice Storm, is actually a good indicator of GPU scaling performance, but we also test Cloud Gate, Sky Diver and Fire Strike to get a measure of all of our systems.
The easiest test, Ice Storm, shows the performance benefits of the Carrizo APUs in the CPU stage, although the dual channel memory for the Kaveri kicks in and gives it the graphics lead. The overall scores however benefit from that high CPU boost, so Carrizo at 15W on single channel wins this round.
Moving up in difficulty to Cloud Gate puts dual channel Kaveri in the lead, although the Toshiba is holding on a bit with its higher thermal skin temperature limit.
The last two benchmarks fall square with the dual channel configuration. The GDDR5 of the discrete graphics card in the Y700 wins out on all of them.
Rocket League
Hilariously simple pick-up-and-play games are great fun. I'm a massive fan of the Katamari franchise for that reason — passing start on a controller and rolling around, picking up things to get bigger, is extremely simple. Until we get a PC version of Katamari that I can benchmark, we'll focus on Rocket League. Rocket League combines the elements of pick-up-and-play, allowing users to jump into a game with other people (or bots) to play football with cars with zero rules. The title is built on Unreal Engine 3 and it allows users to run the game on super-low-end systems while still taxing the big ones. Since the release earlier in 2015, it has sold over 5 million copies and seems to be a fixture at LANs and game shows.
With Rocket League, there is no benchmark mode, so we have to perform a series of automated actions. We take the following approach: Using Fraps to record the time taken to show each frame (and the overall frame rates), we use an automation tool to set up a consistent 4v4 bot match on easy, with the system applying a series of inputs throughout the run, such as switching camera angles and driving around. It turns out that this method is nicely indicative of a real bot match, driving up walls, boosting and even putting in the odd assist, save and/or goal, as weird as that sounds for an automated set of commands. To maintain consistency, the commands we apply are not random but time-fixed, and we also keep the map the same (Denham Park) and the car customization constant. We start recording just after a match starts, and record for 4 minutes of game time, with average frame rates, 99th percentile and frame times all provided. For these tests, we used the 1280x720 resolution at high settings. A bigger explanation of testing can be seen in our AMD A8-7670K APU review.
Built on UE3 and DX9, the game relies heavily on single threaded performance and at this level of detail, memory bandwidth. The Kaveri takes the crown, showing that at this level adding another stick of memory (and making sure you have the right configuration) is more important than a more advanced (or perhaps expensive) APU.
We’ll go into temperatures on the next page.

Including all, AMD and nVidia both at their funeral state! They can not possibly open 22, 14, 10 etc. micron fabric.Intel spended 5 billion dollars to open their new Arizona factory, they will pass lower processes there as well. AMD and nVidia can not get, even a billion dollar profit in these years. It is impossible for them to spend that much money to a new low process factory.
Those little tweaks can not help them to survive....

They don't build factories. TSMC and Samsung (and GloFo to a lesser extent) build factories and do R&D for these processes. Nvidia, AMD. Samsung, Qualcomm, MediaTek and many other companies design chips to the standards of TSMC/Samsung/GloFo and pay money for wafers and running the wafers through the fab.The cost for this per wafer is meant to get all that money back in a few years. And than the process keeps on running for over 10 years sometimes.
It is getting more expensive to get to smaller nodes and the performance increase and power decrease is getting smaller. And costs more to design chips and run wafers. So it is getting harder to find the funds to shrink. Which is one of the reasons Intel has delayed their 10nm process.

Thanks for this review. Really needed for sometime. It was missing from the internet, not just Anandtech.As for the laptops, they say as much as there is to tell. Small Chinese makers, who no one knows they exist, would built better laptops than these. HP, Toshiba and Lenovo in this case, multibillion international giants that seems have all the technicians and the R&D funds necessary, end up producing Laptops with "strange" limitations, bad choices, low quality parts and in the end put prices that, even with all those bad choices and limitations, are NOT lower than those on Intel alternatives. It's almost as if Intel makes the choices for the parts in those laptops. Maybe their is a "trololol" sticker on them somewhere hidden addressed to AMD. I guess that way those big OEM don't make Intel too angry and at the same time, if there is another legal battle between AMD and Intel in the future, they will have enough excuses to show to the judge in their defense, if accused that they supported a monopoly.

This article is what makes Anandtech great. Just keep being like this guys, your work is awesome!I'm going to spend some time clicking your ads, you deserve it :)
As for the "poll" about who's to blame, IMHO it is:
1 - AMD for letting OEMs place Carrizo in designs with terrible panels and single-channel solutions. It's just not good for the brand. "You can't put a Carrizo with single-channel cheap RAM because that's not how it was designed. You want to build bottom-of-the-barrel laptop? We have Carrizo-L for you."
I'm pretty sure Intel has this conversation regarding Core M and Atom/Pentium/Celeron solutions. I know AMD is in a worse solution to negotiate, but downplaying Carrizo like this isn't good for anyone but Intel.
In the end, what AMD needs is a guy who can properly sell their product. Someone who convince the OEMs that good SoCs need to be paired with decent everything-else.
$500 is plenty for a 12/13" IPS/VA screen (even if it's 720/800p), 128GB SSD and 4+4GB DDR3L. Why not pull a Microsoft's Surface and build a decent SKU for that price range so that other OEMs can follow? Contract one OEM to make the device they envisioned, sell it and see all others following suit.
2 - OEMs for apparently not having this ONE guy who calls the shots and knows that selling a crappy system automatically means losing customers. And this ONE other guy (or the same) for not knowing that constantly favoring Intel with their solutions is bound to make the whole company's life miserable if Intel's only competitor kicks the bucket. The consumer isn't meant to know these things, but the OEMs certainly are.
It's 2016. We're way past the age of tricking the customer to buy a terrible user experience through big numbers (like "1TB drive woot"). He/She will feel like the money just wasn't and next time will buy a mac.
Want a $300-400 price point? Get a Carrizo-L with a 128GB SSD and a 720p IPS panel. Want $500-700 Price point? Get a Carrizo with dual-channel, 256GB SSD and 900p/1080p IPS screen.

Anything under 1080p is simply not usable. All these 1366x768 panels are just awful. I have an old netbook with one (12.1") and I've put a small SSD in there and loaded it with Ubuntu. I cannot have a Google Hangouts window open and a web browser open wide enough to view most pages. Basic web browsing + IM - 1366x768 completely fails at the task.testbug00 - Friday, February 5, 2016 - link
768p panels are fine if they are good quality, in 11" laptops.900p good up to 13", and 1080p minimum for 14+.
Honestly I wish we stayed with 8:5 14x9, 16x10, 19x12z
jabber - Saturday, February 6, 2016 - link
Indeed, 768p is fine on my 11" Samsung Chromebook but I would not tolerate it on anything bigger. IMO 1600x900 should be the minimum screen res for budget machines. 1080p for midrange and whatever you like for higher end.jjpcat@hotmail.com - Monday, February 8, 2016 - link
Resolution is not as important as the quality of the panel. I used a Lenovo X1 Carbon. It has a 14" 1080p screen. But it's a TN panel and that just makes it a pain in the ass. I am amazed that Lenovo uses such a lousy panel in its $1k+ laptop while some 10" sub-$200 tablets use IPS.testbug00 - Friday, February 5, 2016 - link
Toshiba can make a $400 chromebook with a good 1080p display. Fully agreed.1080p panel, make it thicker so you can put a larger battery and so the laptop can handle up to 35W from the APU. Do dual channel.
When plugged change APU power mad to 35W, when in battery make it 15W. Probably can be done for $500 for a 15" laptop with an A8. $50/100 upgrade to 128/256GB SSD and $50/100 upgrade to A10/FX.

"The APU contains integrated ‘R6’ level graphics based on GCN 1.0, for 384 streaming processors at a frequency of 533 MHz."Isn't it GCN 1.1?
