Today Qualcomm is announcing a new entry into their premium tier Snapdragon 700-series with the brand-new Snapdragon 750G platform and SoC. The new SoC, as its name implies, lies slightly below the popular Snapdragon 765/768 series released earlier this year, but since it’s a newer design, employs some new IP, such as new Cortex-A77 based performance cores.
The chip on paper looks extremely similar to the Snapdragon 690 which was released last June, however the 750G does have some important distinctions such as the inclusion of mmWave 5G connectivity support which enables it to be Qualcomm’s lowest-end chipset with the feature, positioning itself as an important chipset for the US market.

Looking at the specs, the new Snapdragon 750G upgrades its CPU cores from the Cortex-A76 to newer Cortex-A77’s, clocking them up to 2.2GHz. The A77’s roughly has a 25% performance per clock advantage over the A76, meaning the new chip should be roughly equivalent to the Snapdragon 768G when it comes to CPU performance. Alongside the two performance cores, we also see 6x A55 cores clocked at up to 1.8GHz.
On the GPU side of things, we’re seeing the Adreno 619 GPU which promises a 10% performance boost over the Adreno 618 in the Snapdragon 730G.
Besides the CPU and GPU, the new chip also features a Hexagon 694 DSP and tensor accelerator and promises a combined platform computational throughput of 4TOPs.
Looking at all of the above specifications, they’re oddly familiar and seemingly match those of the Snapdragon 690 SoC, so it’s likely Qualcomm did a lot of design re-use between the two chipset generations.
One further difference from the S690 is the upgrade from 1833 to 2133MHz LPDDR4X memory.
The key difference though to the 6-series sibling however is in the modem: The Snapdragon 750G uses an X52 modem, the same as on the Snapdragon 765/768 chips, with the distinguishing factor to the X51-based variant of the Snapdragon 690 being the additional for mmWave support.
This is an important feature to have for the US market handset designs as it opens up support for the Verizon 5G network, whilst the rest of the world primarily is focusing on sub-6GHz deployments first.
The Snapdragon 750G is manufactured on Samsung’s 8nm process node, and from a device development standpoint is interesting as it’s pin-compatible with the Snapdragon 690 – meaning vendors can pick between the two SoC options without a major platform redesign.
Commercial devices with the Snapdragon 750G are expected to be available by the end of the year, with Xiaomi claiming to be the first vendor to launch a smartphone based on the platform.

I'm still confused about mmWave, it's just marketing currently, right? It's not the sort of thing we see methodically tested (particularly because of the availability), but even casual reviews note that it's blocked by your hand and runs hot. Will this be alleviated by node improvements, or is it too analog heavy?yeeeeman - Tuesday, September 22, 2020 - link
mmWave is just a corner case usage of 5G and it will not take off not even after a few years because it has very bad penetration characteristics and needs a LOT of equipment to install. I see this being used only in the largest cities in center. The rest will use sub 6ghz which is more than enough for 99% of the cases.A5 - Tuesday, September 22, 2020 - link
mmWave is for dense urban cores and venues with large crowds. Verizon has deployed it in small areas of a few cities, and it works, but it will never be your primary connection method.s.yu - Wednesday, September 23, 2020 - link
Stands for any 5G other than the "really low" bands, so, it's a glorified Wifi with more royalties. Any speed 5G on any band can currently reach realistically, Wifi can, with a more stable connection, and mmWave coverage is very close to Wifi in limited controlled areas like shopping centers. CA may bring 5G closer to performance parity in all metrics with Wifi but that's just using more bandwidth, of which there's a limited total. Mettis Aerospace is choosing Wifi over 5G for coverage of their office and production areas, their money is spent smart.shabby - Tuesday, September 22, 2020 - link
The naming scheme is so confusing, I dare anyone to say which core is in the soc without looking at a spec sheet... not happening.Tabalan - Tuesday, September 22, 2020 - link
Hah, look at Kryo cores. You have like 5 different Kryo models based on Cortex A76 and 8 Cortex A55 derivatives XDhttps://en.wikichip.org/wiki/qualcomm/kryo
Plus I believe this list is not up to date XD
Honestly, I 'd love Qualcommto be fined for such top tier BS naming SKUs/cores/GPU and forced to fix it...

Kryo 4 is based on A76 the other 2 numbers are basically meaningless. They are supposed to denote frequency and cache difference, but it's largely irrelevant.s.yu - Tuesday, September 22, 2020 - link
AFAICT this would have trouble competing with MTK, as the 765 series already did.spaceship9876 - Tuesday, September 22, 2020 - link
Still no AV1 hardware decoding :(dotjaz - Tuesday, September 22, 2020 - link
Qualcomm will be the last to support AV1. They are the only SOC vendor not in AOMedia. HiSilicon is not in it either but they are irrelevant for now.
