Why it matters: GPD has spent the past year updating its various ultra-portable PC models to AMD's Ryzen AI chipset, substantially improving their gaming and AI performance. Although the company's latest product, the MicroPC 2, instead uses a low-power Intel Twin Lake CPU, it shares the GPD Pocket 4's updated design at half the price.

Pre-orders for GPD's upcoming MicroPC 2 are now open. With shipping set to begin in September, early-bird pricing for the 7-inch Windows 11 PC with a swivel display starts at $495, around half the cost of the company's other 2025 handhelds.

Starting with last year's GPD Pocket 4, the Hong Kong-based ultra-portable PC maker has rapidly released new models in multiple form factors featuring Ryzen AI 9 processors and Radeon 800M series GPUs. Although the lineup offers better-than-Steam-Deck performance in variants resembling a Sony PSP or a nano laptop, they typically cost over $1,000.



Users waiting for an update to GPD's sub-$500 model from 2019 receive a substantial spec upgrade with the MicroPC 2. Like the GPD Pocket 4, it features various modern expansion ports, a fingerprint scanner, and a touchscreen that turns 180 degrees and folds over the keyboard, essentially making it a pocket 2-in-1.

Although the new Intel N250 Twin Lake CPU maintains the original MicroPC's 4-core, 4-thread arrangement, the boost clock frequency increases from 2.6 GHz to 3.8 GHz, while the L3 cache expands from 4 MB to 6 MB. According to GPD, the MicroPC 2 quintuples its predecessor's Geekbench 6 Vulkan GPU score and exceeds the older model's single-core CPU score by more than an order of magnitude.

Additionally, the newer model supports up to three 4K 60Hz external monitors through an HDMI 2.1 port and two DisplayPort 1.4 USB-C ports. Two additional 10Gbps USB 3.2 Gen2 Type-A ports are also included.

The 1.08-pound, 6.74 x 4.36 x 0.92-inch pocket PC comes with 512GB of storage as standard and supports expansions through PCIe 3.0 NVMe SSDs and microSD cards. The only available memory configuration offers 16 GB of LPDDR5 RAM.

Although the MicroPC 2 ships with Windows 11 24H2, it also supports version 6.14.3 of the stable Linux kernel, allowing users to install Android, ChromeOS, Ubuntu, Debian, and other distros.

GPD's spec sheets compared the 2019 model favorably to the original Microsoft Surface Go, and the MicroPC 2 might have more significant advantages over the Surface Go 3. It has a higher-resolution touch screen, 2-in-1 functionality, and more ports in a package that is nearly a pound and a half lighter and hundreds of dollars cheaper.

Don't know about the 8/6 bit modes, but I can confirm it's 16bpp.

Zaurus - Hardware discussion / C1000, C3xxx: is the PXAfb/LCD 16bpp?
« Last post by DiTBho on July 02, 2025, 05:41:39 pm »
Only consider 640x480: is the PXAfb/LCD 16bit per pixel? RGB565?
doesn't it support 8 bit per color? RGB888?
doesn't it support 6 bit per color? RGB666?

I wrote a framebuffer application, from my testing, it seems 16bpp only.

Is it correct?

Astro Slide - Android / Re: Astro update to V07

Is there anything I can do to help bring a newer version of Android to the Astro Slide?

No. There are several factors necessary, not least of which that we - the community - need Google to sign the builds, be an official Google partner, and the signing keys for the Astro. None of which we have.

https://github.com/planet-community for OSS'd repos.

However, I doubt the Astro will ever be updated. Whilst unsigned OSes (or test keys signed) could be used, it wouldn't be fully functional or supported on the Play Store. Therefore, a lot of apps would refuse to run.

I guess the simplest way to fix this is to by editing the update.sh script to remove the need for the microdrive. The file itself is encoded with a simple character substitution algorithm, here's a simple program to encode/decode it: endecsh.c at the bottom of this page:
https://web.archive.org/web/20160505230130/http://www.h5.dion.ne.jp/~rimemoon/zaurus/memo_008.htm

Code: [Select]
### Check model ###
/sbin/writerominfo
MODEL=`cat /proc/deviceinfo/product`
case "$MODEL" in
    SL-B500|SL-5600)
        ZAURUS='poodle'
        ;;
    SL-6000)

        ZAURUS='c7x0'
        ;;
    SL-C3000|SL-C3100|SL-C3200)
        ZAURUS='c3x00'
        check_for_hdd
        check_for_tar
        ;;
    *)
        echo 'MODEL: '$MODEL 'is unsupported'
        echo ''
        echo 'Please reset'
        while true
        do
        done
        ;;
esac

I wonder what the point is in coding a script that absurdly...
In any case, this is where it probes for the microdrive.

AFAIK the SL-C1000/3x00 models were never directly sold in the US/EU, only imported through resellers. I bought my 1000 from an online japanese shop which exported japanese electronic goods.

I'm really looking forward for your new bootloader, I can help with testing it on my devices. I understand your frustration with the lack of feedback, unfortunately the Zaurus community is these days extremely small. I have answered on your thread for the update issues, sorry I didn't answer earlier.

I have tried to make a mirror of the page with httrack but it was unsuccessful, I'll try again.

Is the source code available?

No, it's NDA'd, if you're referring to the BSP. Bootloader was taken down by Mediatek on GitHub.

There's a few projects mainlining the kernel and such, but AFAIK, I'm the only [active] one here with access.
