Amiga performance on Raspberry PI 2
« on: July 19, 2015, 12:02:47 PM »
Does any one know what sort of performance an Amiga emulator on a PI 2 puts out, Sysinfo and AIBB tests, jit and non jit?
I'm specifically interested in how well it performs vs a real 030 (or 040?)
A600 (3.48/4.46 MIPS) - 2MB Chip, 4MB PCMCIA, 11MB Fast, ACA-620 OC 680EC20@16.67/25MHz, RTC, 512MB CF HD, WB 2.1
A1200 (7.36 MIPS) - 2MB Chip 8MB Fast, MTEC Viper 68030@42MHz MMU, 68882 FPU, RTC, 1GB CF HD, T.Turbo 2, 2 Ext. Floppies, WB 3.0.
Atari 520 STFM - 1MB, Multiface ST.

Commodore 64C - 64K, SD2IEC Drive

SysInfo 4.0 (07/11/2012)

Sam440@800, 4.1FE (builtin E-UAE 0.8.29)
Dhrystones 2149
Mips 2.24
Chip Speed (vs A600) 3.85
MHz 36
>>>>>>>>>Lets go

RetroPie (Raspberry Pi2 quadcore, default setup)
Dhrystones 3348
Mips 3.49
Chip Speed (vs A600) 5.40

Cheers! I had hoped it'd be in the region of 10MIPS. Ah well :)

There is a difference between a real computer and the Raspberry PI.
It is not just a chip that makes a computer but the bus and the architecture of the whole machine.
There are too many benchmarks that you would have to write and run.

@brownb2

The emulator serves its purpose : you cannot tell from the original.
It`s set to 50Hz, vsynced no frame skipping and no sound glitches. Ultra smooth scrolling and quick joystick response time, so it can replace the original HW anytime.

I was hoping to use the PI 2 in a custom keyboard case with a custom straight to uae minimalist linux build if it had decent performance. I had ideas to 3D print something like a mini a4000 case or even just squash it into a rebadged cherry keyboard. Guess I'll wait until the Raspberry PI 4 at £25 comes out!
