  Hard. FEMU is still slower than a regular 040 FPU, although it is moving closer.

Where did you see this?

Yes FEMU is slower than 68080 Hard FPU.
But in many benchmarks FEMU actuually beats 68040 FPU

I think it would be helpful to set some things straight.

My understanding, and maybe you confirm this here:

- Current benchmarks are made on V2 systems. FEMU moved from a SW only solution to a solution which implements important stuff in HW and benefits from AMMX instructions.
- An all HW based FPU will come with V4, no benchmark here so far.

My understanding, and maybe you confirm this here:

1) FEMU started as pure software solution, able to run on any 68K.
This showed the compatibility of FEMU.
Speed of this solution is ~ 0.5 MFLOPS

2) FEMU tuned for 68080, uses CPU for a lot of stuff.
This version of FEMU can only run on APOLLO.
Speed of this version is better ~ 7 MFLOPS

3) The Hard-FPU, the HardFPU can be used in 2 modes
  a) Super scalar, full parallel
    Speed ~ 160 MFLOPS
  b) Debug, serial mode
    Speed ~ 40-60 MFlops    *** This mode we use now ***

4) FEMU + Hard_FPU, we can cherry pick, and select for each Opcode to be excuted in Hardware or by FEMU.
  Speed is depending on the selection of accelerated opcodes.
  Ranges from 7 - 160  MFlops

I guess my knowledge was outdated on this. Good to see that it can indeed outperform a real 040 now. :-)

It obviously must outperform an 040 in all instructions that the 040 doesn't have in hardware... :o)

Makes sense, so the question is then how many TRAP'ed instructions are used in this particular AIBB test? If it was designed towards 040, they would probably have tried to mainly use real 040 FPU instructions or it would be a useless test.

AIBB FMATRIX uses only instructions fully available in 68040 and 68060 FPU.

So there are zero instructions trap'ed on those CPUs

In all seriousness, well done gents, looking forward to V4 - a500 edition!

...UAE... ?

Of course it's UAE (with FPU support in JIT as well), or it is photoshoped :P

  no photoshop, just 4.0 Ghz of Ryzen and WinUAE.
 
  The challenge was "Beat It - If you can" .. and it didn't specify it had to be on Amiga Hardware.
 
  Of course I understand the intent, which is why I'm looking forward to the V4, and planning to buy one myself.

What kind of setup do you have that can clock a 68060 at 128Mhz?
