Dolphin Performance with Exynos AMD Gpu

The next samsung exynos flagships will launch with AMD gpu..how much of a performance boost shall we expect in dolphin considering it was the crappy Adreno and Mali GPU drivers that have held back dolphin android for so long?

Considering that no phones with AMD GPUs have been released yet, it's really hard to know. You'll have to wait and see.

At the very least, I'd expect a much better situation driver-wise. AMD's Linux drivers are currently really good and should share a lot of code with their Android drivers.

That's purely speculation at this moment, but I would be cautiously optimistic at best. Just remember that AMD drivers on Linux used to be pretty crappy (especially the proprietary ones)...

AMD don't do proprietary Linux drivers now. They rewrote a new one from scratch (although I believe it's got a lot of code in common with their proprietary Windows drivers), made it open-source, and that's the backend Mesa uses on modern AMD hardware. The GPU ending up in Samsung phones will be RDNA-based, so there's no benefit to not basing things on their existing Linux driver.

What I meant is that I highly doubt the GPU driver for Android will be open-source, so, even though the current open-source AMD driver for Linux is very good, there's no guarantee they will use the same driver on Android, nor that it would perform similar. Like I said, it's purely speculation for now, but given how crappy GPU drivers are on Android in general and taking into account AMD used to have pretty crappy drivers too, I simply can't blindly go "hell yeah, it will be awesome!" at this time, although I would be very glad if things turns out that way, since it has great potential of pushing Qualcomm and ARM to improve their drivers too in order to compete...

I'm expecting it to be more work to create a crappy driver than a good one. If they base it off their existing Windows or Linux RDNA drivers, it'll be very good by Android standards, so the only way to make it crappy is to start from scratch, but starting from scratch means redoing a bunch of work they've already done for no good reason.

I’m with AnyOldName on this, Intel uses their Linux driver for the android builds, it’s not plug and play but it’s a hell of a lot less work then writing a new driver. I doubt AMD will do anything different, they are going to take the easiest route which is reusing a driver, not writing a new one.
