Full details about Snapdragon 670, 640 and 460 chipsets leaked out ahead of unveiling


Aside from the already unveiled Snapdragon 845 top-tier chipset, Qualcomm plans to launch at least three other SoCs (system on chip) in 2018: Snapdragon 679, 640 and 460.

Although this is the first time we hear about these three unannounced Qualcomm chipsets, we've been able to learn quite a lot of things about them thanks to an image published on Chinese social network Weibo.

The image contains in-depth details about the Snapdragon 845, 670, 640 and 460 chipsets, but the first one is of no concern to us since it has already been made official.

That being said, let's deep dive into the raw information we're being given. First off, it appears that Qualcomm plans to use the same combination of ARM Cortex-A55 and Cortex-A75 architecture in Snapdragon 670 and 640 chipsets, while the Snapdragon 460 is limited to ARM Cortex-A55.

Qualcomm's upcoming Snapdragon 670 chip will be the most powerful in its lineup, second only to the top-tier Snapdragon 845. It comes with four Kryo 360 Gold (derivative of A75) CPUs clocked at 2GHz and four Kryo 385 Silver (derivative of A55) CPUs clocked at 1.6GHz.

The octa-core processor is paired with an Adreno 620 graphics processing unit and Qualcomm's Snapdragon X16 LTE modem.

Next in line, the Snapdragon 640 chipset consists of two Kryo 360 Gold CPUs clocked at 2GHz and six Kryo 385 Silver CPUs clocked at 1.55GHz. It comes with an Adreno 610 graphics processing unit and a Snapdragon X12 LTE modem.

Both Snapdragon 670 and 640 are manufactured using Samsung FinFET 10nm technology, just like the high-end Snapdragon 845 chipset.

Last but not least, Snapdragon 460 chipset is aimed at the low-tier segment but offers more than decent performance on paper. It features four Kryo 360 Silver CPUs clocked at 1.8GHz and four Kryo 360 Silver CPUs clocked at 1.4GHz. Furthermore, the chipset packs an Adreno 605 graphics processing unit and a Snapdragon X12 LTE modem.

Unlike the other three chipsets, Qualcomm Snapdragon 460 is manufactured using Samsung's FinFET 14nm technology, which isn't bad at all.

Although there's no information on when exactly these chipsets will be introduced, chances are that Qualcomm will announce them in late February at MWC (Mobile World Congress) 2018.

Nice. At least QC is moving forward. I like to see how the Exynos matches against the 845

I have a feeling that Qualcomm will become the chipset to beat on midrange phones, but next year we could see Huawei's Kirin 980 surpass it on the high-end. Especially if the 980 is manufactured on the 7nm process and also features Cortex A-75 processors.

ALRIGHT... nice to see those cache sizes increasing... might actually close that gap to the A11 a little

Close the gap? I'm sure you mean "widen the gap" A11 can't even beat 1 year old SD845 in speed test, lol.. And bigger cache size doesn't mean it will be faster, since bigger cache mean more latency. And if the cache hit, it will be a few ms faster at best, and if it miss, and need to access data on memory, the lower sized cache is also faster a few ms. btw, even intel i7-7700K only have 4 × 256 KiB L2 cache, and 8MiB L3 cache, and it can handle multitasking much better than any mobile processors right now

When Samsung was getting it's ass handed to them every year in speed tests: "Oh herp derp... speed tests aren't real world performance and my Samsung will save the world one day!" Literally the moment they FINALLY win some: "Ha slow Apple with their crappy chip! Samsung numba 1!" Fucking hypocritical swine.

wait... did you just compare a desktop cpu to a mobile chip.... bye

Woah, didn't expect either of the 670 or 640 too also be 10LPP Last year the 835 was slight more efficient than the 660 due to the process difference Mid-high end Android phones really are catching up to the flagships Wonder if the 670/640 are lower bins of the 845

I think 640 must reach near 82k antutu and the 670 near 130k

Mid-range android also catch-up in in price too.. look at the new galaxy A8 at $500-$600, OPPO R11s plus (SD660) at 580EUR or Asus Zenfone 4 (SD660) at 500EUR :v (and I'm not sure why Moto, Sony, HTC, Samsung, LG, and nokia didn't make SD660 smartphone :-/ )

The 640 should hopefully be used in $250-$400 phones that perviously had the 625-630
