They will be supported as 64GB LPDDR5X RAM in an 8-channel configuration running at 4.2GHz. The chipset will integrate the Adreno 740 GPU, but will also support external with up to eight PCIe 4.0 lanes. There will be an additional four PCIe 4.0 lanes for NVMe drives, while UFS 4.0 type storage (up to 1TB) will also be supported for a more economical solution. The chip will have additional PCIe 3.0 lanes for peripherals such as a Wi-Fi card or a modem. Still, the 8cx Gen 4 won’t have built-in support for 5G.
It would support two SB 3 10Gbps ports and three USB 4 (Thunderbolt 4) with DisplayPort 1.4a for a triple monitor setup, 5K+4K+4K.
The Adreno 740 will be able to be used for machine learning and will be upgraded with a Hexagon Tensor processor that can reach 45 TOPS in INT8. As is known, Qualcomm is working with Microsoft and Adobe to make the processor compatible with Windows.
The chipset will support video decoding up to 4K/120fps and encoding up to 4K/60fps with various codecs, such as AV1.
Snapdragon 8cx Gen 4 is expected within 2024.
