I agree, that it's very underwhelming, but remember, they only got the silicon a few weeks back (much later than comparable Kaveri chips a year ago), so they haven't had much time to do prototypes.

You are right according to newest preview of Carrizo at CES by Anandtech today --

AMD apparently only received initial silicon back from the fab a few weeks back, and they already have a laptop up and running with the early hardware. In fact, not only did they have a functioning Carrizo laptop but they also had several other working Carrizo systems running Windows. Of course, last year AMD had Kaveri up and running and that launched about five months later, so we’re a bit earlier than that for Carrizo but it’s coming along nicely.

One of the features of Carrizo is full support for H.265 decoding, and as an example of why this is needed they had an Intel system running next to the Carrizo system attempting to playback a 4K H.265 video. While the AMD system was easily able to handle the task without dropping any frames, the Intel system was decoding at what appeared to be single digit frame rates. The 4K content was essentially unwatchable on Intel. Of course that’s easy enough to remedy by adding an appropriate GPU that can handle the decoding, but AMD’s point is that their APU on its own is able to do something that a high-end Intel CPU cannot do without additional hardware.

From the Anandtech article -> "AMD also indicated that their eventual goal is to have the prototype laptop equipped with a discrete GPU for Dual Graphics support, but that isn’t in the current prototype."

Thanks for pointing that out.

I wonder are dual graphics finally working right?

Based on what I have read about desktop dual graphics they don't always work right, and even when they do work right buying a slightly more expensive video card (like the R7 260 or 260X) results in much better performance than running A10-7850K with an R7 25O.

Ideal situation for desktop: Athlon x4 860K with R7 260 rather than A10-7850K + R7 250 (Then, of course, with the Athlon x4 860K and single discrete GPU there would be no cpu throttling as well.)

Based on that I believe we need a very small cheap to produce dedicated hexcore die (with minimal iGPU or no iGPU) for desktop and higher performance laptop that would be paired with single discrete GPU.

(Crossing fingers AMD resists the temptation to bloat a Hexcore die with high amounts of cost adding iGPU when it does nothing for the applications it is meant to serve).

So for lower end gaming laptops: Carrizo is fine.

But for higher performance gaming laptops (that AMD thinks needs stronger graphics), we need a chip that is different than Carrizo. A chip that has two more cores and is cheaper to produce than Carrizo.

AMD has thin and light prototype systems jointly developed with Shuttle Inc. and is showing them off at CES. According to Kevin Lensing, Senior Director, Product Management, AMD, "It's a 'Carrizo'-based system sporting an upcoming mobile discrete GPU and it delivers exceptional, unprecedented gaming performance in a thinner and lighter platform than previously possible due to the energy efficiency and performance focus we have in 'Carrizo.'"

Very surprised to see the AMD Carrizo prototype with discrete graphics.

From TH article, AMD and Shuttle co-developed new type of mobile systems with Carrizo APU, with some models equipped with discrete GPU.

At Shuttle special design website, they have more info about "New Notebook Ecosystem" --

Shuttle new notebook ecosystem is a brand new standard for notebook design that can make the notebook industry more like the desktop industry, enabling smaller LOEMs and brand names to get into the notebook market and enhancing the competitive advantage of LOEMs to compete with MNC (multi-national companies)....

1) Choose display size --> 2) Choose chips --> 3) Choose look --> 4) Choose ship date

Combined with AMD Carrizo/L motherboard, parts ands assembly/test unification, Taiwan PC manufacturers like Shuttle look like they are making it possible for small OEMs anywhere around the world to create more customized notebooks that better fit customer and market needs and demands.

With new games coming out that have quad core cpu and GTX 660 as minimum requirements, APUs in the desktop or laptop again are going to be far behind the curve if you want to play all games, including resource intensive current ones, at any kind of decent settings. This is why I have never been a fan of trying to game on an igp. Yes, they are improving, but it is a constantly moving target. For sure in a desktop, apus make no sense to me for gaming. In a laptop, maybe. You will still have to make a lot of sacrifices, but since you cannot add a discrete card and intel/nVidia units with a discrete card are so expensive, I can see it as an acceptable compromise in a laptop if you are willing to not play some of the more intense games.

Thats the kind of business innovation that can potentially really make a difference to the market. But Intel can do just the same if its a success. But its interesting non the less.
H265, this and other smaller things to differentiate is all the right way instead of this stupid head on battle with Intel that is bound to fail.

It's not really "business innovation" -- the major mobile SoC vendors are including H.265 decode/encode. Broadwell is clearly an architecture aimed at the 2014 timeframe, but delays are pushing it into 2015 where -- as a whole -- it's missing key functionality needed to be competitive in 2015.

That's why Intel can't really afford to delay Skylake to get the most out of the Broadwell design; the latter is just not competitive enough.

Nice first and h265 is very important but skylake will do the same about 4 month later; h265 encode and decode.

People as a whole...don't like to wait. That's why everyone will rush to a new graphics card generation that is 5-10% better even if the competitor already has something that will beat it by 20-30% 3-4 months later.

The Computer market is like that...and the laptop/ultrabook market is no different.

If people want 4K h265 working properly NOW...they will get whatever option is available.

If AMD manages to sell first...then people will obviously buy AMD first.

People hardly care about who does it better later...except for the enthusiasts and high end gamers.

If a new Company invents a CPU that can cook scrambled eggs for you (formerly known as Vishera)...then people will buy that product even if the CPU coming 3 months later can do it at twice the speed.

Yes, a laptop is a much lower power platform (and will come with compromises because of this).

So I think if a person is going to make an attempt at playing the more modern games, the cpu needs to be a separate die from the GPU.

Okay, now with that out of the way, if a OEM wants to use discrete CPU can AMD offer a better value than Intel?

They might offer a better value for the gpu than nVidia, for the cpu, I am not so sure. I am sure they could offer one cheaper, but whether the performance is there is open to debate. I think one of the gaming laptop manufacturers offered an AMD APU with a top of the line discrete gpu at one point, and the price was great, but it was badly cpu limited.

For mobile, I have to wonder how much having a hexcore (triple module) die* would help the performance per watt compared to having three or more threads going through only two modules.

Then, of course, if AMD gets rid of the massive 512 Stream processor iGPU (and uses a smaller DDR3 PHY that doesn't also include GDDR5 functionality) the cost per chip should decrease by quite a bit.

So maybe AMD doesn't beat Intel, but at least is able to considerably improve value in both the higher performance gaming laptop segment (where dGPUs are used) and desktop.

*with very carefully selected amounts of cache.

So much for the FM socket. Seems sockets is a thing of the past at AMD.

Oh the irony about when it was rumoured some other company would go BGA only.

In a way it makes sense. The only place APUs make sense to me is in mobile, where you are power constrained and cannot add a discrete card. Especially with the demanding cpu *and* gpu requirements of new console ports, it seems APUs are getting further and further away from being viable gaming platforms.


Except for cheap cat core laptops though, AMD has been very poor in getting design wins. Lets see if Carrizo has any compelling features that can change that.

Keeps getting crazier and crazier.


So does this mean there isn't going to be a upgrade path for Fm2+ socket?? if this is the case please some one let me know now cause I just purchased a motherboard and a 7850K from newegg and have yet to open it. I can still return it and get something intel based. I just dont want to be stuck on A 7850k With no upgrade options.

What had you expected in terms of upgrade path that makes it so important compared to the 7850K?

Arcording to techreport there is no upgrade path.

Carrizo has the southbridge intergrated like Kabini, so now it is a SOC.

So that should help for OEMs wanting to make ultrabooks or 2 in 1 notebooks.

With that mentioned, It will be interesting to see what the die size ends up (it looks like AMD has reduced L2 cache from 2MB per module to 1MB per module, so that should help die size somewhat. I'm also hoping the DDR PHY is smaller since it will not have GDDR5).

Well so far isn't techreport the only site saying that Carrizo will never make it to Desktop at all?


That said...even IF it never comes (which is kinda ****** up because that means that AMD released an new mainboard for a SINGLE chip)...they might still put out some other Kaveri revisions for FM2+ like they're messing around with the FX line for AM3+

We could still end up seeing something like an A10 7870K and an Athlon 890K or something like it. (with the baseclock simply raised to 4.0 and a boost of 4.3)

Admittedly that would only be selling off cherry picks as higher end chips...but, eh.

But I won't really buy the "no Carrizo for Desktop at all" until I see something more official...a single site reporting that it won't come at all doesn't exactly sound trustworthy to me...unless Im missing something here. Other sites still seem to be wording it rather carefully and say "We don't know or "might not""... which is all that can be said...because as far as I can tell AMD has yet to release an official statement on this.


No cussing in the technical forums.

Is hw actually a traditional desktop cpu?
Is jaguar a desktop cpu because its sold in a huge case?

Well nothing at the moment but I was looking forward to dropping in a Carrizo CPU/APU around spring time.I guess 7850K is going to be it then for the FM2+ socket huh. I really dont need anything more then that I was just being greedy I guess. Kinda freaks me out how everyone is telling me I made the wrong choice choosing the 7850K and that an Intel i3 is twice the strength of a 7850K. Dont know if that is true or not but I dont like to waist my money on crap.All I use my pc for is emulators and ripping and encoding dvd's and blu-rays.so dont know if intels camp has more to offer for this in the el-cheap-o department.Also I never turn my pc off so power saving is a plus for me too.

The Kaveri system should handle those fine. However, an i3 is much better for emulators and quicksync greatly speeds up transcoding.

It makes sense since Carrizo runs at much lower frequencies than Kaveri so any desktop part would be inferior to 7850K (even tho there is certain IPC jump, it's not enough to compensate the frequency deficit vs Kaveri).

If people are looking to buy an AMD "APU" desktop chip as an upgrade from RIchland or Kaveri, the only thing worth mentioning is Zen parts that *should* arrive next year (if AMD doesn't screw up those also).
