Well-known leakster Kuba Wojciechowski shared information about the Qualcomm Snapdragon 8cx Gen4 chip codenamed “Hamoa” today.
Windows on ARM promises well: the specifications of the Snapdragon 8cx Gen 4 have been revealed
Kuba Wojciechowski said in a tweet that Qualcomm is internally testing a SoC codenamed "Hamoa", which can be equipped with up to 8 performance cores and 4 efficiency cores. This processor will be part of the "Windows on Arm" category and will be sold to manufacturers of laptops, PCs and tablets.
Wojciechowski added that the 8 high-performance cores in “Hamoa” can each clock up to 3,4GHz; while the 4 efficiency cores each have a clock frequency of 2,5 GHz, a difference of 900 MHz.
Also, every 4 cores of the chip is a block, and each block has a shared 2MB L12 cache, meaning 3 blocks provide a 2MB L36 cache. They also come with 8MB of L3 cache, 12MB of system-level cache, and 4MB of GPU cache. The SoC will support up to 64GB of LPDDR5X RAM clocked at 4200MHz.
Wojciechowski also said that the Qualcomm Snapdragon 8cx Gen 4 borrows from the Snapdragon 740 Gen 8's Adreno 2 GPU and will support DirectX 12, OpenCL/DirectML and Vulkan 1.3 libraries. There's also support for a discrete GPU via PCIe 4.0.
The GPU will be able to drive 2 4K displays and 1 5K display simultaneously for a total of 3 displays. While the chip also supports 4K/120 FPS decoding and 4K/60 FPS encoding using the AV1.
Furthermore, the Snapdragon 8cx Gen 4 will contain a more powerful Hexagon Tensor NPU capable of delivering up to 45 TOPS of theoretical AI performance.
The processor will support NVMe, UFS 4.0, support for Thunderbolt 4 and DisplayPort 1.4a connectivity. The chip supports Wi-Fi 7 and the communication module is X65.
Finally, the Snapdragon 8cx Gen 4 is expected to be launched in 2024.
