Wait, the SSD is not upgradable?


The HDMI Forum allows calling any HDMI 2.0 port HDMI 2.1 now (true HDMI 2.1 is called HDMI 2.1a). So what's the bandwidth of these HDMI 2.1 ports?
I want to connect a LG OLED C3 42" to watch 4K60Hz HDR content and use full/normal 4:4:4 chroma. This requires 15.68 Gbit/s: en.wikipedia.org/wiki/HDMI#Refresh_frequency_limits_for_HDR10_video, which the HDMI 2.0 can NOT provide.

This is how one calculates this value btw:
15.68 Gbit/s (15.678432 -> 15.68) = ((3840+80)*(2160+62)*3*10*1*60)/10^9.
* 3 -> bits per pixel
* 10 -> 10 bit (required for HDR)
* 1 -> full 444 chroma (for 422 use 2/3 and for 420 use 1/2)
* 60 -> 60 Hz
* +80 and +62 come from the CVT-R2 timing format

For full 120Hz 10bit HDR 444chroma 32.27 Gbit/s are required.
((3840+80)*(2160+127)*3*10*(1)*120)/10^9 -> 32.27 Gbit/s.
HDMI 2.1 FRL4 (32G) can only do 104.7 Hz in this case.
HDMI 2.1 FRL5 (40G) can do 129.3 Hz, so would be enough in this case.

I but it if it had 32GB ram and USB4 and upgradable SSD.
Hope they have better spec models.

What write "3.2K" instead of "3200 x 2000"? Why drop a spec?

There are 16 GB of LPDDR5 RAM -6400 more than enough for 99% of users, and more for that price US$670 possibly Xioami will release more powerful versions of 32Gb but the price of the US$670 laptop is unbeatable. Hopefully it will reach that price in EUROPE and USA.

+1  Ryzen 7 7840HS APU with 8 cores/16 threads and an integrated Radeon 780M graphics accelerator. Additionally, these are the first mobile APUs from AMD to feature dedicated AI acceleration with the new XDNA cores from Xilinx. Complementing the processor is 16GB of LPDDR5-6400 RAM along with a 512GB PCIe 4.0 NVMe SSD. HDMI 2.1 video out, audio jack and a full-size SD card reader. Wireless connectivity is offered through a Wi-Fi 6 + BT 5.2 card. Also included are a 1080p webcam, Dolby Atmos audio, system, and a 72 Wh battery with 100 W GaN fast charger for US$670 in China
I want to see it in the US and EUROPE. They are finally releasing the products that people demand. Xiaomi will earn a lot of money with this laptop for US$670 in China.
