Qualcomm announced the Snapdragon 8cx Gen 3 for PCs in December 2021 and now leaker Kuba Wojciechowski has revealed what the specifications of its successor may be: the Snapdragon 8cx Gen 4, which should be released in the next few years, probably in 2024.
According to the leaker, the Snapdragon 8cx Gen 4 should be equipped with 8 performance cores of 3.4GHz and 4 cores of energy efficiency of 2.5GHz. All of them must be based on Nuvia’s Phoenix architecture, a company acquired by Qualcomm in March 2021.
First of all – the CPU.
As I previously leaked, the highest model of Hamoa has 8 performance cores and 4 power efficient ones. Qualcomm is testing the chip at ~3.4GHz (performance cores) and ~2.5GHz (efficient cores).

New cores must be named Oryon instead of Kryo. In addition, the processor must support up to 64 GB of LPDDR5X RAM in the 8-channel configuration with up to 4.2 GHz, a configuration that resembles servers, as they always support a lot of RAM.
Wojciechowski further details that the chip should have 12 MB of shared L2 cache for each block of 4 cores, 8 MB of L3 cache, 12 MB of system-level cache and an extra 4 MB for graphics.
The GPU must be the Adreno 740, the same as the Snapdragon 8 Gen 2, but the new chip will support external GPUs with up to 8 PCIe 4.0 channels and 4 extras that can be used in NVMe SSDs or dual-channel UFS 4.0 storage with up to 1TB. The Adreno 740 can be used in Machine Learning tasks with the Hexagon Tensor Processor with 45 TOPs in INT8.
Speaking of connections, the Snapdragon 8cx Gen 4 should support up to two 10Gbps USB 3.0 ports, 3 USB 4 ports (Thunderbolt 4) with DisplayPort 1.4a to connect up to three monitors, one 5K resolution and two 4K.
In addition to traditional connections, the chip will also support more PCIe 3.0 inputs for peripherals such as WiFi antenna and modem, since it will not have an integrated 5G modem.
Translated into simpler terms, it is said that the Snapdragon 8cx Gen 4 will have support to decode 4K videos at 120 fps or 60 fps in various codecs like AV1, which may put it at an advantage as Apple does not support it to this format on Silicon M chips.
Qualcomm guaranteed that it will reveal more details about the Snapdragon 8cx Gen 4 in 2023, but has not yet set a date for an event dedicated to it.
