The developer and reverse engineer Kuba Wojciechowski posted on Twitter Extensive information has been re-released on the first commercial chip being developed by the team at start-up Nuvia, which was acquired from Qualcomm a few years ago. The chip, which is also being traded on Apple’s M-series SoCs, could finally make Windows on ARM devices a viable alternative.
Up to 3.4 gigahertz maximum clock rate
According to earlier reports, the SC8380’s 12 cores, as the model number of the “Hamoa” SoC reads, should work at up to 3.4 gigahertz, according to Wojciechowski’s information. Four of the cores will run as “Efficient” cores with a maximum of 2.5 gigahertz, while the other eight can reach the round 3.4 GHz peak clock.
Three blocks of four CPU cores are used, the jewels have 12 megabytes of L2 cache. In addition, there is a total of eight megabytes of L3 cache, which all cores use together. They have 12 megabytes of cache at the system level and also have a very large megabytes of cache for graphics tasks.
It has 64 gigabytes of arbitrary power
According to Wojciechowski, “Hamoa” supports 64 gigabytes of 8-channel LPDDR5x RAM, which can use “additional low-power features” and is said to run at 4200 megahertz. The graphics unit of the chip is the Adreno 740, which IS also used in the current Qualcomm Snapdragon 8 Gen 2 for smartphones. Qualcomm will offer support for DirectX 12, Vulkan 1.3, OpenCL and DirectML, among others.
This mobile GPU from the Snapdragon 8 Gen 2 in the SC8380 is probably not sufficient for demanding graphics display in desktop operation, the “Hamoa” SoC in the 12-core version has eight PCIe 4.0 lanes, via which an additional graphics card can be used can. According to Wojciechowski, most device makers are likely to use the chip in conjunction with an internal GPU.
PC type support for various ports
Also on board are allegedly four PCIe 4.0 lanes for NVMe SSDs that can be configured as 2×2, as well as some PCIe 3.0 lanes for using internal WLAN and mobile network cards. The SoC itself also comes with support for WiFi 7 ex works, although Qualcomm recommends using an internal cellular modem such as the Snapdragon X65 for 5G Internet.
Qualcomm also gave its new desktop SoC a UFS 4.0 controller with support for SSDs of up to one terabyte. There’s also a performance-enhanced Hexagon Tensor processor that’s said to deliver significantly more power for AI tasks.
In order to make the new SoC usable for use in PCs and laptops, Qualcomm also integrated the option of connecting various external devices. Up to two USB 3.1 10 Gpbs ports and three Thunderbolt 4 capable USB 4 ports including DisplayPort 1.4a support. In this way, various external displays can be connected, whereby one 5K and two 4K panels can be displayed simultaneously.
We found “Hamoa” in various countries, and there is no such thing as Qualcomm recently because of its high-quality custom computing cores with the marketing name “Oryon”, which spoke of the availability of devices in 2023. In view of the high prices of laptops with the current Snapdragon 8cx Gen 3, however, it is to be feared that the finished products that will appear then will be anything but cheap.
