Qualcomm Snapdragon 8cx Gen 4

Qualcomm’s Snapdragon 8cx Gen 4 is Apple’s next M-series rival; Rumored specs include 12-core processor, 64GB LPDDR5X RAM, Wi-Fi 7 and more

The latest specs of Qualcomm’s upcoming Snapdragon 8cx Gen 4 are extremely promising, and if the SoC performs like an Apple M-series SoC competitor, we’ll have some real competition in the market. Here are more details we know you’ll be interested in reading.

Snapdragon 8cx Gen 4 will give Windows-based notebooks the ability to get cellular connectivity thanks to Qualcomm’s 5G modem, along with external GPU support

We previously reported that Qualcomm was working on an unnamed SoC codenamed “Hamoa”. Well, it seems that @Za_Raczke, who previously talked about a 12-core SoC, now states that the name of the silicon will be Snapdragon 8cx Gen 4. Apparently, Qualcomm is working on several chipsets, but the one that is said to to offer the highest performance is apparently to offer eight performance cores and four with energy efficiency.

However, he does not specify whether the Snapdragon 8cx Gen 4 will have Qualcomm’s Oryon cores, which are custom solutions that will be possible thanks to the company’s acquisition of Nuvia. Anyway, the information it shares sounds interesting on paper, with the Snapdragon 8cx Gen 4’s performance cores clocked at 3.40GHz, while the energy-efficient ones run at 2.50GHz. It is not confirmed if these clock speeds will remain the same when the silicon runs in commercial products, but we will find out in the future.

Coming to the system cache, the leaker says that each block of 4 cores has 12MB of shared L2 cache, with 8MB of L3 cache. Surprisingly, Qualcomm isn’t developing a new GPU for the Snapdragon 8cx Gen 4, as it’s said to have the Adreno 740, the same GPU that runs in the Snapdragon 8 Gen 2. While it’s still a powerful GPU, limitations could start to show when run on Windows notebooks instead of smartphones.

Where the M2 Pro and M2 Max are limited to LPDDR5 RAM, the Snapdragon 8cx Gen 4 could offer up to 64GB of LPDDR5X support, with the option to run that memory at a lower frequency of 4.20GHz, likely will prioritize battery life when needed. Wi-Fi 7 and an external Snapdragon X65 5G modem are said to be included, along with discrete GPU support for 8 lanes of PCIe 4.0.

There are also 4 lanes (configurable as 2 x 2) of PCIe 4.0 for NVMe drives, with PCIe 3.0 lanes reserved for the Wi-Fi card and modem. If manufacturers want to use integrated UFS 4.0 memory instead of PCIe, Qualcomm also offers that option with the Snapdragon 8cx Gen 4 through a dedicated storage controller. It looks like the chipset maker is going the extra mile, as users will also be able to connect high-resolution monitors, just like they can with the latest 2023 MacBook Pro models.

Not only that, video encoding and decoding performance is said to have improved considerably. We encourage our readers to check out @Za_Raczke’s tweet if they want a detailed overview of what to expect from the Snapdragon 8cx Gen 4. In short, we’re more than excited to see what this chipset will be capable of and with all the information shared today, it should be the Apple M-series competitor we’re all clamoring for.
