These mid range SoC are getting better and better every generation, they should be more than enough for the generation population. Good enough hardware + decent software = good quality lower price phone for everyone, lol
The A53+A72 combo on the 650 and 652 made them punch well above their weight for most tasks while still getting very good efficiency. I thought the octa A53 designs were hampered by the A53 being a slow chip in general, no matter how high they're clocked. It's good to see A53+A73 back in action, these new chips could almost equal flagship performance while being much cheaper and more efficient.
Unless you're gaming on 4k displays, the fancy stuff in the 835 is overkill for most users. Mainly they're for phone/phallic envy and bragging rights.
They also seem to be as rare as hen's teeth, because smartphones using 600 series chipsets are very hard to come by. I don't know whether this is because of production issues or because manufacturers mostly care about high and low end, but that's how it is.
Actually, up to now there were decent 600 series chipsets (like 650-652 or 625), and really crappy ones, such as the SD 617. The really crappy ones are the ones that used eight A53 cores build on 28nm process. By most measures their performance was mediocre. Now in the USA the smartphone market situation is indeed weird in the sense that most smartphone either use the top of the line high end chips, or the manufacturers go for the cheapest crappiest SoC like 617. What truly lacked in the US smartphone market was a true midrange. Thankfully, recently the arrival of Moto G5 Plus (using SD625) and Huawei Honor 6X (using a similar architecture) might have started changing things.
625 is at best a clocked-up 617. The 50+ seem to get actual big.LITTLE, while the sub 50 get 8 x 2012-era cores.
My dad recently needed a smartphone and got what (at the time) was one of the best cheap unlocked phones for Verizon, the G4. I recently compared the benchmarks it alongside my other devices using AnTuTu. The G4 sat around just barely double my old Samsung Galaxy S3, which I upgraded to Nougat using a Lineage nightly. My Shield K1 tablet got double the G4 score, and my current phone, a Windows Alcatel Idol 4S, despite its unoptimized beta benchmark, got about triple the G4's score.
For reference, the Idol 4S cost $400 unlocked and has superior screen resolution, screen color reproduction, build quality, cameras, battery life, battery size, NAND quality, and NAND capacity. I guess you could say its OS is a weakness, but that misses the point: phones using the < 650 series simply fall off the value curve way too hard, and smartphone makers and smartphone chipmakers need to get their act together and fix it or else the market will fall a lot harder than the PC market did.
I would love a 4.7 ou 5 inch phone with a 660 and 3GB of RAM would be more than enough. Also, with that Remix Singularity to be used as a Desktop when in need. It would be a really good phone and problably not too much expense
I don't get it why manufacturers don't have a serious competitor for the non-Plus Iphone. There's no 4.7 inch phone with decent performance in the Android world. That's baffling to me, I'd buy it in a second.
I thought we were talking about decent mid-range chips. 625 is an A53 chip. The sonys I listed use the A72 based 650. Still not as fast as an iphone but also cheaper.
The search link you posted already lists my mentioned X compact. The other three use A53 chips (excluding the iphone).
I wasn't really talking about the chip, they all have some type of mid-range SoC, but as one can see there's like 3-5 under 5" at any cost, from ANY brand.
Only one that fits the bill, with some shortcomings is the Galaxy A3 (2017), but that one is expensive and has a Samsug Exynos SoC. It's small and 4.7" though, but with a glass back.
What do you mean A3 is the only one?! Xperia X compact has 1GB more ram (3 GB), twice the storage (32 GB), better camera, and a 2*A72 + 4*A53 processor (vs. 8*A53), which makes it a decent amount faster. It fits the bill far better.
Again, even though it's not as fast as an iphone, it's quite cheaper. Right now you can get one for $315 on amazon (was $400). The cheapest iphone 7 is $650, and cheapest iphone 6s is $550.
I'm more interested in the efficiency improvements to the LTE modem and the GPU. Even 100 mbit LTE is pointless when mobile data quotas are so low - a gigabit LTE modem at full speed would burn through my monthly quota in a few seconds.
The LTE peak PHY rate is a utterly worthless spec: Even if you have an unlimited data quota, you will be lucky to hit 50mbps in real world life. Most people do have data caps which makes it more moot than ever.
Anyway the SD650 in my Mi Max is awesome SoC, I suspect the only reason why there are so little design wins with the 650/652 because OEMs feel it performs too close to comfort to their S820 flagship phones.
Hey, another Mi Max user :) I was using a Redmi Note 3 previously, also with the SD650, and I absolutely love this processor. It's fast and efficient at stock settings, decently fast and crazy efficient with some tweaks. 11-12 hour screen on time ratings are possible on the Mi Max.
Yeah, I guess the 65x processors offer 80% of flagship performance at less than half the cost. There's no point getting a Mi 5 with an SD820 when a Redmi Note 3 costs less than half.
There's a direct relationship between increase in peak rates and the corresponding increase in real world speeds. Watch this if you're interested in learning more: https://www.youtube.com/watch?v=EyLL8BO-HRg
I suspect it's because the A53 has the best performance/power ratio. Other chips are more powerful (A72 and A73) but use disproportionately more power (on the same manufacturing process); others are more efficient (A35) but are slower.
Why ARM hasn't updated it is a bit of a mystery. As it's their oldest 64-bit chip now, perhaps they'll replace it soon.
To be fair, A53 cores clocked at 2.2-2.5 are more than adequate for a vast majority of CPU related tasks. At 10nm, you could even get away with 2.5-3.0 Ghz for A53 cores, which should give it a single threaded performance close to a Cortex A57, which is pretty good for the midrange.
Looking at Geekbench scores, A53 cores built on 14nm process (like SD625) are on the same level of performance as SD800. (Yes, SD800 is old, but its level of performance is adequate for a cheap smartphone today).
@ LiverpoolFC5903 What about OoO execution and better branch predictor. No matter how much higher you clock the A53, it will still be behind, if compared to bigger (A57, A72, A73) cores...
A53 is not that bad when it's built on 14nm process. The smartphones using the 625 (built in the same architecture) have certainly punched above their height in terms of performance while having very good battery life (e.g. Moto Z Play). I wouldn't really mind a 630 in my smartphone. The crappy A53 cores were the ones built on the 28nm process.
A73 is not cheaper, it just takes up less silicon die space than A72 core, so it reduces the 'SOC manufacturer' cost but a Licensee has to pay more on every A73 core produced or modified vs A72 core, as A73 is a newer core.
Why I am saying that it is still A72 and A53 is because- snapdragon 660 only provide 20% improvement in cpu performance compared to 653, given that it has transitioned from HPM to FinFet, 28nm to 14nm, ARM A72 to custom core 'kryo 260', It should give 20% performance improvement, if based on A72 core, and at least 30% increase in performance, if based on A73 core.
( Note: A73 core provide upto 15% increase in performance when implemented on same process node and upto 30% improvement in performance when implemented on 10nm process node as compared to an A72 core ).
Where did you get this information from? From what I recall, the A73 is barely ~10% faster than the A72 overall at the same process node and clock speed, and actually slower in many tasks.
I have read, probably ( i am not sure), that A73 is better than A72 in integer operations but perform worse in floating-point operations. You have said A73 is slower in many tasks, can you elaborate?
Matt Humrick Yeah, i just browsed that URL and it was about snapdragon 835 and its 'kryo 280' core but i am talking about snapdragon 660 and its 'kryo 260' core. Did you test this one ('kryo 260' core)? If 'kryo 280' is based on A73 core, it does not mean that all 'kryo 2xx' will be based on A73 core as well. If it is really based on A73 core, then why 'only 20%' performance improvement in cpu as compared to snapdragon 653, given that it has transitioned from HPM to FinFet, 28nm to 14nm, ARM A72 to custom core 'kryo 260'. Will you test 'kryo 260' in coming days?
Xiaomi and smaller Chinese brands used the 65x in their midrange devices that could have cannibalized flagship sales. Only Samsung charged premium prices for a midrange 650 on their Galaxy A9 Pro.
Seriously, where are all the socs with cortex a35? Has anyone heard anything besides the deca core mediatek? Maybe it didnt turn out so good. Snapdragon 630 with 4x a35 and 4x a53 would be awesome.
Indeed. The A35 is for really low end stuff whereas the A53 is a midrange general purpose design. A53+A73 is the best midrange design so far, with the efficient A53 cluster doing most of the work while the A73 cluster is used for short, fast bursts like for loading apps and laying out web pages.
If you look at the bottom of the first graph here, you can see that (on the same process) A53 still has better perf/power than even A73. A73 has more performance but less efficiency. A35 comes from the other side, as vladx says -- less performance, more efficiency. A53 performance itself is very much 'good enough' as phones like the Moto G4 show.
The A53 cores built on a modern 14nm or 16nm process can achieve the same level of performance as Snapdragon 800 cores, while being very easy on the battery. Not bad for a cheap, under-300USD smartphones. The crappy ones were the A53s in the SoCs like SD617, which were built on 28nm process.
Have you seen phones with 650 at mid-range price other than Xiaomi's? It could be the same with 660. It will be priced slightly below than flagship. Even Xiaomi downgrade Redmi Note 4 to 625
I don't know if we can lump 800/801 into the same class with 808. The 800/801 were using 32 bit Krait cores, while the 808 was 64 bit SoC using A57 + A53 cores. To me, it looks like the SD 660 is basically a SD 820 done the right way (in the sense of using a more modern manufacturing process, resulting in better efficiency and thermal properties).
The SD 660 Could have easily been called the SD 818. The only part of the SoC that is slower than SD 820 is the Adreno 512 gpu. But, even the Adreno 512 should allow you to play any game on the Play Store on high settings with solid frame rates.
No sense to use 2x32bits Memory on both S835 and S660 Bandwidth will be mostly used by GPU for texturing and S660's one is far smaller (see on PC, we only see DDR4 when GDDR5 is used for long time on GPU)
I think it's 2x16 You can see it on Geekbench scores... Memory bandwidth shows about 10.5GB/s on S660 And about 17GB/S on S835

That first one is a 5", you can get a 5" with 625 and 4100 mAh battery on Aliexpress for half of what the Sony costs.There are only a few 4.5 - 4.8" phones with good res and mid-range hardware, since 2015/2016. If I do a search I find only these on GSMArena.

To me, it looks like the SD 660 is basically a SD 820 done the right way (in the sense of using a more modern manufacturing process, resulting in better efficiency and thermal properties).SquarePeg - Wednesday, May 10, 2017 - link
The SD 660 Could have easily been called the SD 818. The only part of the SoC that is slower than SD 820 is the Adreno 512 gpu. But, even the Adreno 512 should allow you to play any game on the Play Store on high settings with solid frame rates.Suraj tiwari - Friday, May 12, 2017 - link
@LiverpoolFC5903I wonder where you saw A53 having equal single-threaded performance as
A57/A72.
Here is the 'trusted' site -

See A53 in mediatek is clocked at higher rate than A57. Did you see the performance difference between A53 and A57?
Let alone comparing A53 to A72.

No sense to use 2x32bits Memory on both S835 and S660Bandwidth will be mostly used by GPU for texturing and S660's one is far smaller (see on PC, we only see DDR4 when GDDR5 is used for long time on GPU)
I think it's 2x16
You can see it on Geekbench scores...
Memory bandwidth shows about 10.5GB/s on S660
And about 17GB/S on S835
