Apollo 68060 chip memory acess speed

[utri007]

I have heard that Apollo accelerators has a unstandard way to Access Chip memory. It supposed to be faster than Blizzard accelerators has.

Now I have a two 68060 66mhz accelerators Blizzard and Apollo.

So I decide to make a module.

Apollo is a LOT faster! Not just Chip RAM but also hard drive speed.

Interesting tests..
Are you using the same hd for both tests?
Is the blizzard kicked into synchronous mode on scsi? or is it on ide?

I have heard this about the Apollo vs Blizzard. My understanding is if you want to overclock/go for raw benchmarks you go Apollo, if you leave at 50MHz, want stable and most compatible as an 060 can be, go Blizzard.

Hard drive test are made with internal IDE. Hard driuves are different, 2.5 and 3.5, so tests are not so accurate with them. Apollo has a 3.5 drive and Blizzard 2.5 drive.

SysInfo test tells about 800kb faster IDE with APollo than Blizzard.

Chip ram operations are accurate. Both Amigas has same kickstart and pacthes.

Chip ram operations are 1.39x - 1.55x faster with Apollo and that is a lot. Not just few prosents wich I waited to see.

I once did a couple of SysSpeed Modules to compare a Blizzard vs Apollo (both patched to the max and running @ 80Mhz)

Apollo_1260_80Mhz_AGA

Blizzy_1260_80Mhz_AGA

the bliz scsi would likely give you 4x~ faster speed,but good to know what comparison was made.

How does fast ram compare?

[utri007]

Blizzard is marginally faster, something like 0,5%

Generally to get 80mhz CPU like Novacoder did, ram speed needs to be decraded. After that Apollo has ofcouse much slover ram. But with 66mhz no need to decrade ram speed.

I have an Apollo 1260.  Which 68060 libraries should I use for best performance and compatibility?  Which FPU patcher?

There is only one that is still supported.

Both Amigas uses mmulibs
