Qualcomm could follow Apple’s lead and go bold with Snapdragon 8 Gen 2 design

Written by admin

just last month, and rumors have already started about its successor, which we assume will be known as the Snapdragon 8 Gen 2. Most chips intended for Android phones out there are octa-core. CPU with three clusters, but it looks like the Gen 2 will have a different layout.

Snapdragon 8 Gen 2 gets four medium cores

Yummy Digital Chat Stationwho has many credible leaks under his belt claims that SM8550 Kailua, which apparently is the model number and codename for the Snapdragon 8 Gen 2 respectively, will be based on Taiwan Semiconductor Manufacturing Company (TSMC)’s 4nm process, which was also announced. used for the 8 Plus Gen 1.
What’s more interesting, though, is that the chip will deviate from the general design with one large Arm core, three medium cores, and four power-efficient cores used by most chipmakers for their high-end chips that support the best android phones out there.

In fact, even the Snapdragon 8 Plus Gen 1 is based on that setup, with one Cortex-X2 core, three Cortex A710 cores, and four Cortex A510 cores. There was a time not too long ago when chips had four large cores and four small cores. For example, the Snapdragon 845 had four A75-based cores and four A55-based cores.

The Snapdragon 8 Gen 2 will seemingly shake things up. As per today’s leak, the chip will have one layer by one Makalu generation core, another cluster with two Makalu generation cores, followed by two Matterhorn cores and three Klein R1 cores.

If that sounds like a word salad, Arm’s Matterhorn generation is referring to its 2021 Cortex CPUs, while Makalu is intended for 2022 phones.

That means the Snapdragon 8 Gen 2 will have one Cortex-X3 core, yet to be announced, two Cortex-A720 cores, two 2021 A710 cores, and three older A510 cores. The tipster adds that it comes with the Adreno 740 GPU.

Qualcomm still isn’t ready to abandon an instructional architecture that Apple got rid of a long time ago

Arm announced the Matterhorn and Makalu generations in 2020 and said they would offer a 30 percent increase in performance. The company had also said that from 2022 designs, the Cortex-A large cores would only support the 64-bit instruction set.

That’s because 64-bit code leads to a faster and more responsive experience compared to 32-bit. Chinese outlet IT-home reports that OPPO, Vivo and Xiaomi no longer allow new 32-bit apps in their app stores to improve the user experience.

Chipmakers are apparently planning to phase out support for 32-bit code, which seems to explain why the Snapdragon 8 Gen 2 chip will also have A710 and A510 cores. Otherwise, if it only opts for Makalu cores, next year’s advanced Android phones may not be able to run some older apps.

Apple has an architecture license with Arm that allows it to make changes to designs. The smartphone chips have six cores: two high-performance cores and four energy-efficient cores, and are thought to be much faster than Android chips, especially since the company has been using a 64-bit instructional architecture since 2013.
Tailored from Google The Tensor chip that powers the Pixel 6 and 6 Pro also has an unusual setup aimed at improving efficiency and features two Arm Cortex-X1 cores, as well as older mid- and lower-power cores, which it seems. to have worked well for the company .

So while it’s not uncommon for chipmakers to use old CPU designs, it’s still not clear why Qualcomm chooses a different design.

Which seems odd – as noted by android authority – is that instead of sticking to Arm’s merged-core approach for the Cortex-A510, where two cores are linked together to allow for resource sharing, Qualcomm is also opting for a single core with its own dedicated resources, which could reduce efficiency.
Could it be that efficiency gains from 2+2 medium cores compensate for that? It seems likely, given that well-known leaker Ice Universe said late last month that the Snapdragon 8 Gen 2 is a lot more efficient than the Snapdragon 8 Plus Gen 1.
Still, it’s hard to fully understand what Qualcomm is up to here, but the specs rumors have certainly piqued our interest. Will this be the year Qualcomm’s Snapdragon 8 Gen 2 chip finally takes over the iPhone’s A-series SoC? Well, it’s too early to comment on that, but if Qualcomm deviates from Arm’s chip design guidelines, it’s definitely onto something.
