Qualcomm Snapdragon 8cx Gen4 detail exposure: 8 3.4GHz performance cores + 4 2.5GHz efficiency cores, maximum 64GB memory
CTOnews.com January 22 news, reliable source Kuba Wojciechowski shared information about Qualcomm Snapdragon 8cx Gen4 chip code-named "Hamoa" in its latest tweet. CTOnews.com learned that the revelations were a follow-up to his revelations in November last year, sharing more information about the chip.
Core:
Kuba Wojciechowski said in a tweet that Qualcomm is testing a SoC code-named "Hamoa" that can have up to eight performance and four efficiency cores. Qualcomm is likely to test a variety of combined designs before deciding to sell to notebook manufacturers.
Wojciechowski tweets the eight performance cores in "Hamoa", each with a clock rate of 3.4GHz, while each of the four efficiency cores has a clock rate of 2.5GHz, a difference of 900MHz.
Cache:
In addition, every four cores of the chip is a block, and each block has 12 MB L2 shared cache, that is to say, 3 blocks provide 36MB L2 cache. In addition, L3 cache for 8MB, system-level cache for 12MB and GPU cache for 4MB are also provided.
Memory:
The SoC will support a LPDDR5X RAM of up to 64 GB with a main frequency of 4200 MHz.
GPU:
Wojciechowski also said that Qualcomm Snapdragon 8cx Gen 4 borrows from Adreno 740GPU of Snapdragon 8 Gen 2 and will support DirectX 12, OpenCL / DirectML and Vulkan 1.3 libraries.
Stand-alone GPU is even supported through PCIe 4.0.
The GPU will be able to drive two 4K monitors and one 5K monitor at the same time for a total of three monitors.
The chip also supports 4K / 120 FPS decoding and 4K / 60 FPS encoding using AV1 codecs.
NPU:
In addition, Snapdragon 8cx Gen 4 will include a more powerful Hexagon Tensor NPU that provides theoretical AI performance of up to 45 TOPS.
Connection:
Qualcomm will support NVMe, UFS 4.0, Thunderbolt 4 connections and DisplayPort 1.4a. The chip supports Wi-Fi 7 and the communication module is X65.
Release time:
The Snapdragon 8cx Gen 4 is expected to be launched in 2024, which means that Apple's Apple Silicon will still be the main character on the ARM laptop chip for the next year or two.
