What do people think about the GPU on the steam deck?

2 tflops sounds pretty good for such a small screen. I'm running an RX5700XT on my desktop which has ~10 tflops of fp32 performance (for a 1440p/144Hz screen). 2 tflops looks like it'll be plenty for a 720p screen at 60Hz.

Battery life is probably going to suck, but that's not unexpected for these kinds of devices.

One of my coworkers just ordered one of these as a replacement for his laptop. He says its more powerful than his current (Linux) thinkpad since it has a Zen2/RDNA2 CPU/GPU combo while costing less than half the price of his laptop. Valve must be subsidizing these quite a bit.

Maybe the loss-leader pricing might make these good for other tasks.
I've seen Raspberry Pi compute "clusters" before, maybe someone will put 10 of these together to make a Steam Deck cluster.
Cant waiting to start folding@home on my portable gaming handheld!

gonna break out the m.2 slot to full pci-e and plug in a 3090 for convenient portable gaming on the go

If it supports eGPUs, you might actually be able to do this relatively easily with USB-C.

Of course, you'd have to spend 3-4 times the price of a Steam Deck on the eGPU enclosure and the GPU itself, but maybe that's worth it to have raytracing on the go

Just a word of caution for people thinking of running Windows off an SD card: I’ve done it before on a different device (Surface Pro) and it was horribly slow. (Disclaimer that I’ve not tried it on a Steam Deck, which might be better)

Most SD cards have really poor IO performance, like 100 times worse than the built-in NVMe.

Linux is fine running off an SD card especially if you set some kernel flags to do heavier in-memory caching. But I couldn’t find a good way to make Windows tolerable on an SD card. I ended up uninstalling it a few days later.
