Qualcomm announces the Snapdragon 765 with the Snapdragon X52 5G modem and support for 120Hz displays and 192MP cameras




Facing increased competition from MediaTek, Huawei, and Samsung in price and spec-conscientious markets like India and China, Qualcomm created a new Snapdragon 700 series of upper mid-range chipsets last year. The 700 series brings the best of Qualcomm’s premium 800 series but at a lower price point. The most recent iteration, the Snapdragon 730, even introduced a gaming variant to meet the growing demand of the mobile gaming industry. Now, Qualcomm is once again introducing a new member to the 700 series: the Qualcomm Snapdragon 765. The new SoC brings support for 5G connectivity, high refresh rate displays, and high-quality imaging to the mid-range price tier.

In India, China, and other parts of Asia, phone makers like Xiaomi, Realme, OPPO, Huawei/Honor, Vivo, Lenovo/Motorola, and Samsung are locked in a competition to see who can deliver the best specifications at the best price. The cost of the SoC, of course, factors into how low a brand can price their smartphone, which is why we see a lot of mid-range smartphones with Qualcomm’s latest 600 series SoC or one of MediaTek’s Helio P series SoCs.
In between this range and the premium flagship tier is where the upper mid-range devices like the Xiaomi Mi 9T, Realme X2, Redmi Note 8 Pro, Xiaomi Mi Note 10, Honor 9X, and Samsung Galaxy A80 come in. These devices have features that were previously exclusive to the flagship tier, such as 3+ cameras, an ultra high-resolution main camera, 6+GB of RAM, and very fast wired charging. With the Qualcomm Snapdragon 765, next year’s upper mid-range devices could have features like 120Hz displays, 5G network support, 12GB of RAM, super slow motion video, and more. Here’s how the Snapdragon 765 could make that happen.

To begin with, here’s a table I made compares the Snapdragon 730 with the new Qualcomm Snapdragon 765. The table may be hard to follow if you’re not already familiar with most of the terms. Underneath the table, I have provided explanations of all the year-on-year improvements and new features.



CPU

The Snapdragon 765 features minor improvements in CPU performance compared to the Snapdragon 730. That’s because there aren’t any major architectural changes to the CPU cores. Instead, Qualcomm added a new “Prime” CPU core cluster consisting of a lone core clocked at up to 2.3GHz. There’s also a lone “Performance” core clocked at up to 2.2GHz. Qualcomm says these two cores are based on its customized Kryo 475 architecture, which is derived from the ARM Cortex-A76 design. Lastly, there are 6 ARM Cortex-A55-based Efficiency CPU cores clocked at up to 1.8GHz. Thus, the core cluster configuration of the Snapdragon 765 is 1+1+6 compared to 2+6 on the Snapdragon 730.

It is likely that the transition from an 8nm manufacturing process to a 7nm manufacturing process yields some improvements in CPU power efficiency, and thus, average performance.

GPU

Qualcomm’s new Adreno 620 GPU in the Snapdragon 765 supposedly offers 20% better performance and efficiency compared to the Adreno 618 GPU in the Snapdragon 730. We don’t know the maximum clock speed of the GPU or any other details that might explain the increase in performance and efficiency, but again, it’s likely that the transition from an 8nm to a 7nm manufacturing process yielded some benefits in those regards.

Qualcomm added support for HDR10+ and Dolby Vision video playback in the Adreno 620. The Adreno 618, in comparison, only supported 4K HDR10 PQ.

Display

One of the best capabilities of the new Snapdragon 765, according to Qualcomm, is the fact that it supports on-device displays up to FHD+ resolution and a 120Hz refresh rate. The GPU is largely responsible for pushing pixels to the display, and with higher resolutions and refresh rates, there are a lot more pixels to push.

So far, high refresh rate panels have been exclusively found in premium flagship smartphones. However, the Snapdragon 835-powered Razer Phone had a 120Hz display back in 2017, and this year alone we’ve seen nearly a dozen smartphones with high refresh rate displays. It’s only a matter of time until the first upper mid-range device launches with one, and when it does, it’ll likely be powered by the Qualcomm Snapdragon 765. Interestingly, Qualcomm confirmed to us that the GPU in the Snapdragon 730 is already capable of supporting FHD+ @ 120Hz, but we don’t know how much more capable the Snapdragon 765 is at sustaining 120fps than the Snapdragon 730.

AI

Qualcomm’s advancements in on-device artificial intelligence are best seen each year in the new Snapdragon 800 series, but the company has been bringing some of these advancements down to the Snapdragon 700 series as well. Qualcomm doubled the AI performance of the Snapdragon 730 versus the Snapdragon 710 by introducing their 4th generation AI Engine, adding more ALUs in the GPU, improving dot product instruction performance in the CPU, and adding their Hexagon Tensor Accelerator (HTA).

Qualcomm is continuing to improve the AI performance in the Snapdragon 700 series with the introduction of their 5th generation AI Engine and a newer Hexagon Tensor Accelerator in the Snapdragon 765. Overall, the Snapdragon 765G SoC is capable of 5.5 TOPS (trillions of operations) performance, closing in on the Snapdragon 855’s 7 TOPS performance
A discrete component called the “Qualcomm Sensing Hub” has also been announced. The Sensing Hub is designed for always-on detection of audio with support for multiple hotwords such as “Hey/Okay Google” and “Alexa.” Utilizing <1 mW of power, the chip’s power drain is basically negligible. As the sensor’s framework is scalable, developers can use Qualcomm’s Hexagon SDKs to create their own audio-activated features.

ISP

While the Spectra ISP in the Snapdragon 800 series has received a huge bump in performance and functionality with this generation, the improvements in the Snapdragon 700 series are more modest. As far as we can tell, Qualcomm hasn’t disclosed any notable improvements in photography. Qualcomm boasts that the Snapdragon 765’s Spectra 355 ISP is capable of processing 192MP photos, but without ZSL at that resolution, don’t expect smartphone makers to ever allow you to capture full 192MP photos. Qualcomm did state that camera vendors are working on image sensors with these ultra high megapixel counts, though.

What we do know has changed in this generation is video capture. The Spectra 355 is capable of processing slow motion 720p videos at 480fps compared to the Spectra 350’s 720p@240fps support. In addition, the Spectra 355 adds support for video capture in HDR10+.
Qualcomm is aggressively positioning itself at the forefront of 5G technology, and they’re banking on the Snapdragon 765 to bring 5G-enabled smartphones to the masses. The Snapdragon 765 is Qualcomm’s first SoC with integrated 5G, meaning the 5G modem is on the die. This results in lower power consumption as the smartphone won’t have to provide power for a discrete modem. However, that doesn’t mean the Snapdragon 765 is superior at 5G connectivity compared to the Snapdragon 865.

The Snapdragon X52, like the Snapdragon X55, is a multi-mode modem, meaning it is capable of 2G, 3G, 4G LTE, and 5G (sub-6GHz and mmWave) connections. When comparing the specifications of the two modems, however, you’ll find that the Snapdragon X52 offers half the maximum theoretical 5G download speed (3.7Gbps vs 7.5Gbps), half the maximum theoretical 5G upload speed (1.6Gbps vs 3.0Gbps), half the mmWave bandwidth (400MHz vs 800MHz), and half the sub-6GHz bandwidth (100MHz vs 200MHz) compared to the discrete Snapdragon X55 modem paired with the Snapdragon 865. It’s a similar story for the 4G LTE speeds.

Yet, the mmWave 5G network roll out is still underway, so most users won’t be seeing 5G speeds that are anywhere close to the theoretical maximums anyway. What’s more important about the Snapdragon X52 is the fact that it supports global bands and has all the technology that Qualcomm has developed to improve throughput, reliability, and usability. Technologies like Dynamic Spectrum Sharing, global 5G roaming, multi-SIM 5G, 5G PowerSave, and Qualcomm Wideband Envelope Tracking are all implemented in the Snapdragon X52 modem, just to name a few.

Location

Like the latest 800 series chipsets, the Snapdragon 765 supports dual frequency GNSS, which can result in more precise location tracking if the smartphone has a chip capable of supporting multiple frequencies (L1+L5 or E1+E5a). This is the first Snapdragon 700 series chipset that supports this functionality.

Charging

Qualcomm’s latest fast charging technology is still a work-in-progress, it seems, as 27W Quick Charge 4+ is still the fast charge technology of choice for the Snapdragon 765. However, Qualcomm has added a new “Quick Charge AI” technology that supposedly extends the longevity of your smartphone’s battery. Compared to the Snapdragon 730, a device with the Snapdragon 765 will last for up to 200 more battery life cycles. Qualcomm did not share many details on how Quick Charge AI works, but it could be using dynamic voltage adjustment like USB-PD PPS (USB-Power Delivery Programmable Power Supply.)
