"Apparently Qualcomm is so confident in Hydra that it is cutting down the number of cores to four, instead of the eight found in the Snapdragon 810, which it promises will still deliver a whopping 35% performance improvement. This is coupled with a new Adreno 530 GPU, which accounts for an additional 40% improvement in the graphics department, as well as 30% better power efficiency."

What do you guys think?

 

[ShintaiDK]

Less faster cores=better.

However there is rumours that it still...overheats.

MediaTek have gone completely bananas. Their X30? is 4x2 clusters. Half the clusters are identical, just at different speed. I cant see anything but silly PR in that.

 

[NTMBK]

Presumably this means that Hydra scales well enough that big.LITTLE isn't necessary. Good news!

Waiting for NVIDIA answer. They could start to implement SMT. Apple could try too.

NVIDIA isn't even in the smartphone AP game anymore.

Looks solid. It'll be interesting to see how it does in the real world.

 

[dark zero]

NVIDIA isn't even in the smartphone AP game anymore.

But is still alive on the ARM market. And they can move to the Chromebook market.

And now to Qualcomm... Their desing is promising.. But The overheating is lethal for them.

When was the last time you saw a consumer-oriented NVIDIA Tegra design win?

Hydra CPU w/ -35% performance improvement

Should be:

~35%

otherwise it's really poor...

 

[krumme]

The interesting is what is not specified. The most important:
Cpu efficiency.
I think thats bad news.

But the dsp is as usual interesting. But i cant decifer anything from it apart from the obvious. Is it eg. Able to stabilize 4k60hz video?

They have the best Android TV, but the market for that is still minuscule.

we previously believed it would be called Kryo, yet the document at hand refers to it as Hydra.

Kryo is the official name but they somehow trust more some "leaked" papers

 

[NTMBK]

But that isn't a design win, that is their own internal product.

You are right, my bad.

 

[sm625]

3 cores might even be smarter. As much as I hate apple, they at least know how to make a cpu. This eight+ core crap needs to die as fast a death as possible, or at least go into hibernation for the next 6 years.

 

[krumme]

An update mostly about GPU
http://www.anandtech.com/show/9522/qualcomm-adreno-530-510-snapdragon-820
Seems they are gunning for better efficiency on the GPU side, but if the bragging is right it looks fine.

We still have to wait for Kryo cpu news.

"Devices based on Snapdragon 820 are expected to be available in 1H 2016."
Argg. Seem a little late to me

Is perhaps beeing tested in Samsung S7
http://www.gforgames.com/gadgets/samsung-galaxy-s7-snapdragon-820-leak-48041/

"Back in July we heard that the Galaxy S7 is codenamed Jungfrau and that Samsung is strongly considering Snapdragon 820 as a potential chipset for its device (the same report mentioned that an Exynos version is also in the works).

Friday, the Galaxy S7 returned under the spotlight as a new rumor claimed that Samsung has switched to “Agile” development process in order to be able to finalize its upcoming flagship by December and thus shaving 1 to 2 month from the entire planning-to-store-shelves life cycle.

Now a new leaks brings the Jungfrau and the Snapdragon 820 pair back to the forefront."

 

[podspi]

If Samsung is considering it for the S7 that is good news that QC has got their groove back. Thank goodness. It would have been really disappointing if it was only ARM (and Apple) in the AP core business.

Will Samsung switch back to using a QC solution for their flagships? I hope this news about 35-40% improvements pans out - IIRC the S810 was pulling 1300/3800 in geekbench while the 7420 was putting out a phenomenal 1500/5400 single/multi core!



1300/3800 x 1.4 (being generous) put the S820 in the realm of 1800/5400, that's faster than 7420, Apple A8, and it even beats Intel Broadwell Core M. If they can provide that kind of performance I see no reason to use Samsung SoCs with their sub-par GPU cluster. Adreno graphics have always been superior to the stock ARM Mali GPUs.

1800 single core Geekbench would indeed be impressive. However i imagine that could be possible with Cortex A72 as well within an upcoming Exynos SoC.

Yes, A72 on 16FF+ should be able to hit/exceed 1800 in GB3.

It's somewhat interesting that Qualcomm and ARM are promising almost the exact same level of performance improvement (~35%), with Kryo and A72 respectively.

Makes me wonder if the other ARM manufacturers out there (Mediatek and the like) might have an easier time competing against Qualcomm this time around. This is of course assuming that the actual performance of the two designs live up to the promises (or fail to do so by an equal amount).

ARM cores have always been competitive with Qualcomm's CPUs on performance.

A9 was higher performance than the original Kraits, and A15 was easily Krait 400 level.

CPU performance is just one part of the mobile SoC equation.

You're absolutely right. I was probably thinking back to the original HTC One X results with Tegra 3 vs Snapdragon S4, where Krait won. But later implementations of A9 (on 28nm), like Exynos 4412 seems to have had the upper hand versus Krait. The A15 versus Krait 400 is also correct.

Either way CPU performance was arguably never Qualcomm's main competitive advantage, it was their modems. Given their reduced patent portfolio for 4G (relatively speaking), there should arguably be more room for other competitors.

So I guess all in all, Qualcomm will still be seeing significantly tougher competition this time around, but I was incorrect in saying that it would be the result of a shakeup in the CPU landscape specifically (although the CPUs might of course still play a role, depending upon how they turn out).

MediaTek already has an 8173 out with 2x A72 and 2x A53. It's been demo'd in tablet and chromebook form.


Looks like at 1.6Ghz the 8173 is getting 1300-1700 single thread. It's spec'd to clock up to 2.4 Ghz when on a 14/16nm process though (8173 is on 20nm).

It's beating an Apple A7 in single thread, and at 2Ghz+ should beat an A8 as well. I tend to ignore multi-core results on phones, as long as it has 2 cores.

And this is a low end part. Huawei is supposed to release a 2.4Ghz quad A72+Quad A53 on Sept 2.

Also QualComm 618 and 620.

1484 at 1.57 GHz is extremely impressive, considering the targeted boost frequency of A72 (and as you mentioned some of the results on geekbench even go as high as 1698), but can we be certain that geekbench is reporting the frequency correctly for this chip?
