Qualcomm Announces Snapdragon 750G: Cortex-A77 & mmWave in the Premium Rangeby Andrei Frumusanu on September 22, 2020 9:30 AM EST

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.

Seems like Andrei doesn't understand what design reuse is. SD690 and SD750G are obviously the same chip of the same generation. Just like SD710/670. They just lowered the frequency and disabled mmWave for 690, that's all.
Andrei Frumusanu - Tuesday, September 22, 2020 - linkNo. They are different designs.
tkSteveFOX - Thursday, September 24, 2020 - linkA tad too late. Exynos 980 came with 2xA77 cores mire than 6 months ago on 8nm.
Mtk 820 will eat this for breakfast, along with Kirin 820.
Qualcomm have released a bunch of mid tier SoCs which were always behind the competition (690/720/730/732/765/768)
In fact, the last time QC had a real beast of a mid-range product was the SD660 which had 4 big cores at the time and was like an SD835 with half the GPU cut down.
Why not get a 4xA77 with lower clocks (1x2.4 and 3x2.2), 4xA55s and an Adreno 620 for the $3-400 segment to replace 765G and 768G?
