Qualcomm Krait & MSM8960 @ AnandTech

[Mariner]

I don't know about reviews, but you can buy them.

AFAIK that's not the only one.

Without knowing anything about what battery these tablets are using, as well as the rest of the hardware, we can't draw any conclusions about the power consumption of the SoC. For instance, Archos Gamepad gets terrible battery life in no small part because it has a terrible battery.

But what exactly does A31 have to do with RK3188 or 28nm?

Buy one? Doubt it. Order one? Certainly.

These Chinese stores aren't averse to accepting orders before they have the devices available. They also tend to overstate battery life so it is rather concerning that this store is only saying 4-5 hours from an 8000mAh battery. The best RK3066 tablets (albeit with a lower-resolution screen) get 8+ hours from a similarly-sized battery.

I mentioned the A31 as I wondered if you had confused it with the RK3188. There are certainly A31 devices available and in the hands of consumers now. Not sure if this a 28nm chip, however. Most sellers seem to claim that it is but then you often need to take these claims with a pinch of salt until further information is available.

I presume you meant to say that TSMC had nearly 100% market share during 2012, right? The way you're wording it makes it seem as if TSMC will have nearly 100% market share during 2013 as well....

Oh crap, yes, I meant 2012, sorry. I'm not yet used to "this year" being 2013.

My mistake. I actually didn't even think about that.. so many sites are selling them already >_> But it looks like you're right and no one actually has one.

I'm used to a lot of other lies from these sellers too, like with clock speeds (sometimes even the SoC vendor joins in!)

Oh no, I didn't confuse the two, although I did think A31 was a good example of devices showing up almost as soon as the thing is announced. Guess that isn't so for RK3188. For what it's worth, A31 is not 28nm - I think you'll find most Chinese SoCs are fabbed in China (or maybe Taiwan?) and they just moved on past 55nm there. Rockchip using GF is kind of a big move for them.

It will be interesting to see what the RK3188 brings to the table when it becomes available as I've been impressed with the performance of my tablet which uses RK3066.

The big irritation for me at the moment is that many of the better apps aren't available on Android tablets as yet. Considering how many capable Android tablets have been sold, I'm surprised that some of the better iPad apps haven't been ported across as yet.

Obviously not handheld related, but it doesn't come as a surprise either:

I'm assuming linking to existing articles on it won't get me in trouble with Qualcomm legal.

Thanks. I saw what I wanted to see. Finally on black & white that Adreno320 is clocked actually at 400MHz. Adreno330 is at 450MHz and should have a bunch of more units since otherwise it wouldn't get a performance increase rating of 30% compared to the 320. Jesus the 320 has 8 TMUs? Where the heck does all the fillrate vanish in realtime fillrate tests? Same TMU amount for 330.

Adreno420 (which I assume will be for 2014?) is at 500MHz and will have DX11.1 API support, but no performance estimates Still 8 TMUs though.

Processor frequencies and everything else looks more than just good. Given the CPU frequency, higher bandwidth and additional GPU performance in the APQ8074 the formerly stated 50% compared to its predecessor are perfectly realistic IMO.

I realise the typical secrecy semis have with those things, but with that roadmap Qualcomm doesn't have to be worried, rather the exact opposite.

***edit: to give you a picture what I mean with the fillrate I think but am not absolutely sure either that the T604 has 4 TMUs (probably clocked at 533MHz). Have a look at the offscreen 1080p fillrate scores here: http://www.glbenchmark.com/compare.jsp?D1=Google+Nexus+4&D2=Google+Nexus+10&cols=2

Even if I'd assume that the T604 has 8 and not 4 TMUs, the difference is still relatively big. At 4 for the 604 it rather gets ridiculous. Does the Adreno3x0 need much more bandwidth than a T6xx or else how much does Adreno's driver ie tiling exactly suck?

Qualcomm has supposedly delayed releasing new reference drivers for Snapdragon S3 so they could focus on Krait. Hoping this leads to performance boost for Adreno 320

Something more detail about adreno320/330?

Thanks guys for getting this info..it backs up what we saw on the dragon snapdragon demo thing..I noticed it said 450mhz..which left me puzzled. ..how can it be possible for them to increase gaming performance by 50% and compute by 2x with just a small clock increase and better bandwidth?

Perhaps the drivers are the key..we know that previous adreno uarch had an in efficient compiler and needed really good drivers to get the best out of it...qualcomm was initially slow at at this but future driver releases sped things up by massive amounts...

I do wonder whether adreno 320 is the same? Pehaps it is bandwidth starved also? Perhaps what we are looking at here is just improved drivers/bandwidth with a small adjustment to clock and shaders?..

I think that is more likely than loads more execution units...

One thing is for certain..qualcomm is very honest and accurate with their performance projections. ...if any thing they actually undershoot it when driver improvements are factored in later on down the road.

One more thing...that dragon demo runs at 30fps..according to qualcomm..I believe them, and it looks a hell of alot more taxing than gl benchmark 2.5 offscreen wouldnt you say?

APQ8064 is missing the T after model number to be Snapdragon S600, but there is the figure 600 next to the chip model.

 

[RedVi]

Is APQ8084 tablet only? There's no mention of an LTE modem. It kind of makes sense to bring the new 400 series of GPU to tablet first, along with H.265 playback. This would go well with a 2560x1600+ screen. Whatever succeeds that may couple the new GPU with a new CPU on the 20nm process for phones.

APQ = application processor without modem
MSM = AP with modem, second digit indicates type of modem.

S600?

 

[Ailuros]

S600?

I suppose so. Given that I doubt that they raised clocks for the GPU if you add with speculative math another 30% on top of that score for Adreno330 the result is rather scary and it explains rather well why Qualcomm was so "bold" with its statements against Tegra4.

Peak CPU frequency for the Samsung device is at 1890MHz according to the entry at Kishonti's database. The Nexus7 tablet successor?

dunnon what that is, but the cpu is clocking @ 1.9Ghz

As I said it could be the Nexus7 successor for Google with the CPU clocked higher. It could of course also be a ~25% higher clocked Adreno320 (ie ~500MHz), but I'd rather be optimistic and hope for driver improvements
