Snapdragon 820 specs reveal a next-gen 14nm process, better than in A9 or Exynos 7420
posted by Daniel P. / Nov 11, 2015, 5:09 AM
The difference between the Low Power Early (LPE) and Low Power Plus or Performance (LPP) generations is what it says on the tin - LPE are the inaugural production batches of a die shrink, proving the viability of the move to this node, and generally exhibits a much faster performance with less power consumption in the same footptint as the previous generation.
Delivering maximum performance and low power consumption, Kryo is QTI’s first custom 64-bit quad-core CPU, manufactured in advanced 14nm FinFET LPP processThe LPP process, on the other hand, is an improvement within the same 14nm generation, bringing about a higher performance within an even smaller power envelope than 14nm LPE, and LPP is what Snapdragon 820 will be built on, as you can see in the PDF specs sheet below.
We'd wager to guess that the upcoming Exynos 8890 - which is another candidate to go into the future Galaxy S7 - will also be built on Samsung's second-gen 14nm LPP process, so these two should be crushing the benchmarks when they land. At the same time, they should be more frugal than the 14nm LPE chips like the Apple A9 in iPhone 6s, or the Exynos 7420 in the Galaxy S6, so we can't wait to see what the Galaxy S7 will have on offer in the power draw/performance ratio department.

Another interesting thing is that its a big.LITTLE quad core (or dual dual core?) Its has a dual core cluster of "Kryo HP" @ 2.2Ghz And has a dual core cluster of "Kryo LP" @ 1.6-7Ghz

It's not big.LITTLE...all 4 cores have same architecture...only difference is in clock speed and cache configuration. 2 x 2 cluster is unnecessary move by qualcomm...whatever qualcomm is trying to achieve with this could be done easily with just cpu governor! Anyway impressive soc...looking forward to 2016 devices.

Better be ''better'' or else Qualcomm will surely bite the dust

If the 820 is only marginally better than the 7420, the Exynos 8890 gonna be miles ahead again.. I feel Qualcomm's high end CPU's are falling into the mid range CPU bracket due to the 810 heating issues slowing them down.

Still wonder why none of these soc makers use the same principal as Apple and Nvidia and use a wider superscalar. This has proven to be quite fast and less prone to throttle.

from what I understand the reason might be efficiency, although that is becoming a moot point now - why waste perfectly good methods when you can easily clock the cores higher.

Please note all the speed you see in the new iPhone 6s as nothing to do with the A9 CPU, but is linked to them moving away from Emmc HD like Samsung did and just like when Samsung did it the speed of the OS and the phone goes up big time as you can r and w at the same time

Can't wait for the Lumia 1050.

I wanna see what the new exynos brings to the table as well.

From records, the Exynos knocked Qualcomn outs easily so I think it's going to be the same thing for this time again. At least Samsung lets Qualcomn enjoy their game for the time being. When Samsung releases their monster Exynos 8890, we will see the SD 820 is a joke. Don't get me wrong, the 820 can be the 8890's rival, but only if the thermal issue is gone. And without Samsung's 14nm performance, it's nothing.

Hallyu you need to stop been so blind. In past years Qualcomm beaten Samsung year after year. Exynos 54XX where overheating mess as well. Its not because qualcomm made the mistake to use crappy big little architecture ( thats turn any soc into an oven even the last exynos throttle by 40% after 15 min. Wake up man.
