The 636 does not have cortex a53 for the big cores, but cortex a73. It has the same configuration as snapdragon 660, but with lower clock speeds and weaker GPU. This is clear since it has only 1.8 GHz max frequency opposite to the the 625 (which is supposedly be slower 40% by qualcomm's saying than 636) that has a higher max frequency. The only way to improve the performance this way is to use different cores than a53.
Cortex A53 isn't a LITTLE. It has dual role as big or LITTLE. The more power efficient core is Cortex A35 which is a True LITTLE core
Comparing with Snapdragon 660, SD636 has slower CPU (1.8 GHz vs 2.2 GHz) and lower GPU (Adreno 509 vs Adreno 512). It may be good upgrade path from hugely popular SD625 APU, which is used in many mid-range phones like Xiaomi Redmi Note 4x and recent Xiaomi Mi A1. But its predecessor SD630 and it superior SD660 both were not so popular for some reason, so I don't think that SD636 will be as popular as SD625.
Kiyasariin, 18 Oct 2017the 260. it's the same cores as the SD660 but slightly lower clocked (1.8GHz@S636 vs 2.2 GHz@S... morethe SD660 apparently has big.LITTLE configuration, with the little has 1.8 GHz frequency, and probably it's a Kryo 260 that based on Cortex-A53. Won't be surprised if SD636 use all of the little config, just like the SD625

Anonymous, 17 Oct 2017It will take about a year From the announcement like this to products in the shops... So Expe... moreYeah, that's true. As it is most companies are still shoving the SD625 from Feb 2016 in nearly all their phones *coughXiaomicough* ...
Oh, definitely it's a good news for the mid-rangers (segment). Although is still better if they opt for the SD660 instead than for the SD636. But if they (the brands) skip the SD660, AT LEAST now they can use the SD636 instead of the SD630 (slightly better). Moreover, also excellent news that it support QC4. Hopefully all the phones (mid-rangers, etc) that will use it, will include the QC4 as well. (Based on this, it is appropriate to mention that unlike Samsung, that they'll are still using just the QC2 even for/in the S8 duo & Note 8, shame on them. But let's hope that from the S9 onwards they will start including the QC4+ or Exynos equal to it [HOPEFULLY!!!]).
Which kryo is this? There were two types of kryo 260 in sd660, performance(a73), efficiency(a53). If it's just another 8 core a53 then there won't be much difference from 625.
danny15, 17 Oct 2017Why is it still on 14 nm? Is not time yet to move on better process like 10 nm? Because chip price get higher even if die size will shrink.
Well, I was interested in the Redmi Note 5, but today searching... I found that it'll probably use this SD636 and be the first phone with that SoC, although if it's released this year the first version will come with the P25 and later in 2018Q1 they'll release the Redmi Note 5 with the SD636 (Weibo source), probably the global version too. I wanted the Snapdragon version.
Too late for me, I guess. Now looking for other alternatives, perhaps the Nubia Z17 MiniS but I wish something with bigger screen. I hope there'll be something new before Christmas with bigger screen, B20 and similar performance/price or look into something older in offer with custom Oreo roms available. : (
R31ya, 17 Oct 2017What the hell? SD636?
We haven't even got SD630 in my place.
And SD636 use Kyro 260 instead ... moreIt will take about a year From the announcement like this to products in the shops...
So Expect to see 630 at the end of this year an 636 maybe in the next summer or next autumn, most likely christmast 2018 so about a year From now.
I like it. Because now, OEMs can use these and still sell good quality mid range devices
SD 636 is an updated version from previous model, SD 630 which mean some improvement from octa core 2,2 GHz A53 to octa core 1,8 GHz Kryo 260 (the same as SD 660 used it only with smaller clock), Adreno 160 GFLOPS to Adreno 175 GFLOPS, and MAYBE 15% - 20% improvements on Antutu score.
Can wait for an update version from SD 660. Since 630 becoming 636, perhaps 660 will become 666, DEVIL INSIDE. Perhaps, Kryo 280 (which used in 835) or A73 maybe with smaller clock (such as 2,0 GHz), Adreno 513 with 280 GFLOPS, and about 110K - 120K on Antutu scores.
Anonymous, 17 Oct 201740% faster cores, so finally matching the iPhone 5 in single coreAll this chipset speeds really don't mean much in real life performance. Most apps like Facebook, whatsapp, etc.. Users only use one core for it's service. The old snapdragon 801 still runs smooth.
Anonymous, 17 Oct 201740% faster cores, so finally matching the iPhone 5 in single coreMore like +30% performance.
...but its not an improvement in the Multicore score, that's an improvement in the single-core score, which is much more important. When comparing the QSD 835 to the QSD 845.
This boost is thanks to Qualcomm's Cortex A73 customised cores, unlike their off-the-shelf cores in the QSD 835, that they've been designing for awhile. These new "Kryo 300" cores are now almost equal to the Cortex A75, which we won't see until the end of 2018 (Samsung Note9/Huawei Mate11). We saw a similar scenario with Qualcomm designing the custom Cortex A9 = Krait 300 microarchitecture (QSD 200/400/600) which mimicked the Cortex A15. And again, with the custom Cortex A15 = Krait 400 microarchitecture (QSD 800/801/805) which mimicked the Cortex A17. And once more with the custom Cortex A57 = Kryo 100 microarchitecture (QSD 820/821) which mimicked the Cortex A72 cores.
It should be slightly faster than the Apple A9 SoC in single-core speeds, but slower than the Apple A10 SoC. In terms of Multicore, it should be well above the Apple A10 but slightly below the Apple A11 SoC.
Overall, I would say its almost on-par with the Apple A10 SoC... which is an impressive feat, well done Qualcomm!

Sony Fanboy Bitches, 17 Oct 2017SD845 might be announced at CES or earlier/later than that, and the first one to use it might ... moreUnveiling and sell are two things. QC provided some SD835 samples to any OEM that wants it, just to develop the product and showing it to the press. And based on a recent report posted here, Samsung still has called dibs to the first batch of SD845.
