AMD Launches Carrizo: The Laptop Leap of Efficiency and Architecture Updates
by Ian Cutress on June 2, 2015 9:00 PM ESTAMD Secure Processor
One of the final pieces in the puzzle is AMD’s Secure Processor, which they seemed to have called the PSP. The concept of the security processor has evolved over time, but the premise of a locked down area to perform sensitive work that is both hidden and cryptographically sealed appeals to a particular element of the population, particularly when it comes to business.
AMD’s PSP is based around a single 32-bit ARM Cortex-A5, with its own isolated ROM and SRAM but has access to system memory and resources. It contains logic to deal with the x86 POST process but also features a cryptographic co-processor.
ARM has been promoting TrustZone for a couple of years now, and AMD has been tinkering with their Secure Processor proposition for almost as long although relatively few explanations from AMD outside ‘it is there’ have come forward.
Final Thoughts
Sometimes a name can inspire change. Carrizo isn’t one of those names, and when hearing the words ‘AMD’s notebook processor’, those words have not instilled much hope in the past, much to AMD’s chagrin no doubt. Despite this, we come away from Carrizo with a significantly positive impression because this feels more than just another Bulldozer-based update.
If you can say in a sentence ‘more performance, less power and less die area’, it almost sounds like a holy trifecta of goals a processor designer can only hope to accomplish. Normally a processor engineer is all about performance, so it takes an adjustment in thinking to focus more so on power, but AMD is promising this with Carrizo. Part of this will be down to the effectiveness of the high density libraries (which according to the slides should also mean less power or more performance for less die area) but also the implementation of the higher bandwidth encoder, new video playback pathway and optimization of power through the frequency planes. Doubling the L1 data cache for no loss in latency will have definite impacts to IPC, as well as the better prefetch and branch prediction.
Technically, on paper, all the blocks in play look exciting and every little margin can help AMD build a better APU. It merely requires validation of the results we have been presented along with a killer device to go along with it, something which AMD has lacked in the past and reviewers have had trouble getting their hands on. We are in discussions with AMD to get the sufficient tools to test independently a number of the claims, and to see if AMD’s Carrizo has potential.

If you think as gaming as hard-core gaming, latest and greatest titles, max settings, high res, then yes, I agree.But, as a father, I can tell you that there are tons of kids that are OK with "some" gaming and for whom the parents won't fork 1Kusd for a powerful gaming rig, and for which AMD really offers a price/performance ratio that cannot be compared.

The marketing for this particular launch is specifically targeting players of MOBAs, such as League of Legends, DOTA2, and Starcraft. The active players of those 3 games is about 100 million people. You can argue that's not a majority of users, but AMD has never had a majority share of laptops, and 100 million people is a sizable market.I expect that AMD will make more direct appeals for that group of people, such as sponsoring tournaments, and generally trying to establish mindshare for laptops in that group.
I don't think targeting that particular niche market is a bad idea, personally.

Their APU's can perform on those games very well, but also so can all of Intel's HD series graphics, at least every rendition I've ever seen.It won't be an easy crowd to win over. Even if the requirements for their sport only warrant a $300 computer, you know they are gamers and still want their supercomputers.

I agree with this. But it also doesn't make sense to me why they have. CPU's have been commodity devices for some time now and it makes no sense to me whatsoever that the average consumer would buy Intel when they can transparently get the very same performance for their needs with a much cheaper AMD processor. This, plus the fact that AMD does so well with essentially embedded systems (XBox, Playstation) even though they are 'AMD Inside' suggests to me that their struggle is largely due to marketing failures rather than technological ones.medi03 - Thursday, June 4, 2015 - link
Athlon 64th were outsold by Intel's Prescott that was:a) slower
b) consumed more power
c) more expensive
also because of "AMD's marketing failures" I guess...

no it's the skin that surrounds the amd heart - and that skin is cheap and ugly - that's how amd plays their cards... a low class dirt bucket cheap compile - so even if it could be made to look great and "feel very expensive and well constructed" - those creating AMD skin WON'T DO IT.FlushedBubblyJock - Tuesday, June 9, 2015 - link
Thinking again I will admit when browsing new laptops in person AMD GAMING ! is not something I can ever recall seeing ... it's very tough sometimes just to get the basic specs visible by the box stores....AS118 - Wednesday, June 3, 2015 - link
I don't ind 1366 x 768 on a smaller screen (14" and less for me) and think that AMD's performance on 900p and below's great. I also think that it's sad that more people don't know about them and how capable they are.Many casual customers who would want that extra gaming performance don't even know it exists on A8's and A10's.

Yeah, I don't mind 1366 x 768 myself on smaller laptops, and gaming at that resolution is a thing with AMD APU's. Gaming performance on the A8 and especially A10 APU's is why I've been getting AMD Processors on Laptops for years.I don't need a lot of GPU oomph on my laptops, just needed the option to play casual games and not that hard to run stuff like WoW (well, before WoD at least) on the go.
