Quake 2 on PiStorm32 accelerator!

So what RPi is recommended to get ready for this? Would a 4gb or 8gb RPi 4 Model B give better performance? Will the Ram of the model I choose make much difference for Amiga use?

Forget Quake2, check those sysinfo scores out. I'd like to see some CPU bound application benchmarks.

The point is it's real and orders of magnitude cheaper than a Vampire/V4 whatever you're supposed to call them these days!

Ice me a Drake and put my Bird in the Fire for holy smokes there's a 32-bit Storm in my Pi baby!

Imagine how well it'll run with a RK3588 CM5 plugged in instead of a Raspi CM4(provided it's ever supported). :D

That cushion in my lap is just because I feel a bit cold,umkay?

Michal is doing great work with Emu68.

OK, so you like benchmarks! However, in the real world we're supply constrained and if ordered today we won't get a RPi 4 Model B until September on back order!

So, I again ask nicely, what difference will a 4gb versus an 8gb version of the RPi 4 Model B make to 'real world' Amiga PiStorm performance? There's about a £25 price difference which is not unsubstantial!

You can look etc at dnetc benchmark: https://youtu.be/9ELrJVyP_V8
Or, if you prefer 720p video played with riva: https://youtu.be/IHsSE0S0aAY
Or, if you overclock the pi4 or cm4, you can play 720p mpeg2: https://twitter.com/claude1079/status/1610345329726988289?s=61&t=Zj_HmF3GJMTQOXJ22EcCQQ

It all depends on the code that gets compiled to aarch64. Sometimes one can squeeze 1MIPS/1MHz, sometimes less.

@michalsc

Is there any support for native code inclusion? I can imagine things like datatypes and codecs benefitting enormously from being able to have some aarch SIMD assistance

No, not yet. But if it comes then not in a transparent way, but rather in form of a library which will be used to acces QPU and VPU.

FYI, the mobile Ryzen 7040 APU has a block of Xilinx FPGA technology marketed as Ryzen AI.

It would be cool, albeit controversial, to allow something akin to WUP/PUP to allow native code execution. I'm not sure how well you could expose the vector extensions via a library, except for a set of standard algorithms, but the number of potential uses for vector code is, well, as good as limitless.

I tried to determine a relevancy factor for that statement but realised it was not with in the domain of normal numbers.

How feasible is a CPU slot version for A3000/A4000 ?

If you remember my AmiWest presentation this is exactly something I want to avoid - a growing zoo of different binary targets for AmigaOS, therefore no, I would still prefer to go through a library approach.

Well, PiStorm is open hardware/open source, so everything is possible :) But that is up to those who would do that.

None.

The vampire was fun for a while but i really regret spending all that money on them now :D

@michalsc

The Warp accekerators and ZZ9000 have an ARM on board so it might be worth having a discussion with CS LAB and MNT to create a standard for running ARM code from Amiga OS 68k. MNT have already done some work with an SDK and some example code.
