Qualcomm Snapdragon 8cx Gen 4 Details Leaked

Qualcomm is working on a next-gen processor- Snapdragon 8cx Gen 4 that will go toe to toe against Apple’s M1 and M2 series processors. A new leak has offered details about the processor. The Snapdragon 8cx Gen 4 should be substantially more powerful than the current crop of SoCs available in Windows On-ARM laptops because it has 12 CPU cores and the GPU from the Snapdragon 8 Gen 2 processor.

A developer named Kuba Wojciechowski has added details regarding the Snapdragon 8cx Gen 4 to a string of tweets he made in November. According to Wojciechowski, Qualcomm is evaluating an SoC codenamed Hamoa with up to 8 performance cores and 4 efficiency cores, similar to Intel’s Alder Lake and Raptor Lake platforms. Plus, leaks also suggest that the SoC might arrive in different variants. Although we wouldn’t rule out Qualcomm following Apple and selling a variety of core configurations under the same brand name, it’s possible that Qualcomm is testing different designs before deciding on core arrangements to sell to laptop manufacturers.

Snapdragon 8cx Gen 4 purported specs

The 8 P cores of “Hamoa,” as per Wojciechowski, can boost up to 3.4 GHz, which is 900 MHz faster than its 4 E cores, which Qualcomm limits to 2.5 GHz. The SoC includes 8 MB L3, 12 MB system-level, 4 MB GPU, and 36 MB of L2 cache divided into three clusters. Wojciechowski further adds that the new SoC will include an Adreno 740 GPU similar to the Snapdragon 8 Gen 2. As a result, it will support DirectX 12, OpenCL/DirectML, and Vulkan 1.3 libraries. Rumors also suggest that the GPU will be able to power three displays at once, two of which can run at 4K and one at 5K. Similar to the Apple M2 platform, 4K/120 FPS decoding and 4K/60 FPS encoding with the AV1 codec will also be supported.

Additionally, a more powerful Hexagon Tensor NPU that can produce up to 45 TOPS of theoretical AI performance will arrive in the Snapdragon 8cx Gen 4 chip. Even better, the SoC will enable separate GPUs through PCIe 4.0 and up to 64 GB of 4200 MHz LPDDR5X RAM. Moreover, Qualcomm will also provide Thunderbolt 4 connectivity with DisplayPort 1.4a support, along with NVMe and UFS 4.0 support.
