I thought you were supposed to run your FPU at the same speed as your Processor...?

Anemos · 12 November 2009, 13:31

On my Blizz 1230/50,i have one 68882 FPU at 33MH,working well,no problems.
(some links you post not working..)

I'd go for no FPU. You'll never need one and they just use more electricity.

alexh · 12 November 2009, 14:07

No, absolutely nothing.

seuden · 12 November 2009, 14:16

What exactly could it be used for then? There must be something?

Best reason ever not to buy an FPU. *sigh*

Raytracers use them to do the calculations f.e. and a lot of 040/060 demos need/use an FPU too.

So they can be useful then.

yup, so it's wise to buy a full 040/060 and not EC/LC ones. But for 030 ... I think only a few demos need an FPU.

Hungry Horace · 12 November 2009, 14:44

do any, or could any, emulators use an FPU to help speed things up a bit?

seuden · 12 November 2009, 14:45

So if you're gaming then there is absolutely no need for an FPU what so ever and if you do have one take it out 'cos it can save you 5p/month?

Hungry Horace · 12 November 2009, 14:47

it's a status symbol.

the "must have" accessory of 2010 is definately an FPU for your A1200.

not only does it sound good, but it lets people know you can afford the extra 5p per month. Nothing says "player" like an FPU.

68020 or 68030: you don't need FPU if you have to ask

68040 or 68060: you want FPU version.

I was thinking more about the unnecessary heat inside your case & increased demand on PSU.

Non that I know of. It would be very unlikely any could use an FPU, everything you're emulating is integer based.

Great post Alexh, care to elaborate? Or even better, send corrections to the ADA team so they can fix any obvious errors? *shakes head*
