3 more NatAmi's - Yippee!

Yep cant wait to get my hands on one of these puppies, SuperAGA with all the new chunky modes, resolutions and 100-200 times faster than a classic AGA.
 
Gunner has been playing/tuning with the 060 card and says it can keep up with 600mhz PPC Amiga in mem copy.
 
MEMORY READ 145 MB/sec (Optimised Code)
MEMORY READ 114 MB/sec (Average Code)
MEMORY WRITE 155 MB/sec
MEMORY COPY 140 MB/sec

He also says he isnt finished tuning it yet which is cool, I wonder how the N050 FPGA and the DDR2 memory will stack up to these results ;-)

Memory interface of this "600MHz powerpc amiga" is the partcularly weak spot in it. Beating it is hardly worth cheering about.
 
Comparing the results against 7447 with 166MHz bus and proper chipset would have given a slightly different picture:
 
write: 774 MB/s
read: 375MB/s
 
(Actual figures from Mac mini G4 1.5GHz, unoptimized C code)
 
And if we go to anything computational the G4 crushes classic, and even natami, regardless of if it runs real 060 or some FPGA 68k emulation. Some figures here: http://via.i-networx.de/bench_en.html

Yes Piru MOS in a Mac is impressive, I am sure Gunner was refering to Pegasos with OS 4.x if you read the whole natami thread.
 
But dont you think those figures are impressive concidering how old the 060 processor is ?? I think it shows how mature the 060 architecture is, and it is only running @ 120mhz. Gunner also says he is aiming for 180 MB/s.
I am sure the N050 + DDR2 will score alot higher, I guess it would also depend on the memory controller Natami MX has.
I do know it is using a 64bit bus for the DDR2 memory, Oh well time will tell.

alexh is the only one with his head up his own backside.
 
I wouldn't worry about anything he ever has to say, he only joins in when there's an opportunity to tell someone they're wrong, but never actually offers any new or useful information in his posts or takes into consideration the fact that other people have different views on computing than he does.

Cammy thats a bit harsh :laughing: but this time Alex is wrong ..
 

I don't even think it will replace your Amiga in the short term as compatibility will be it's Achilles heel for the short term.

Alex you know NatAmi stands for Native Amiga right? The following is from the NatAmi website:
 
Topics on Compatibility:

• The NatAmi is compatible to the OCS/ECS/AGA AMIGA chipsets.
• AMIGA Kickstarts 1.2, 1.3, 3.0, 3.1 are supported
• We recommend AMIGA Workbench 3.0 - 3.9 to be used
• AMIGA 4000/1200 register compatible IDE controller on board (enhanced, PIO and DMA)
• Existing AMIGA IDE harddrives can be used unchanged
• AMIGA DD/HD floppy support using standard PC Floppy drives.
• Floppy drive access can be redirected using ADF images on HD.
• AMIGA applications, games and demos that run on classic 68060-Systems,

will run on NATAMI as long as they have not any constrains to chipset timings/limitations.

• Direct hitting of the Amiga hardware works natively.

Querying CIA, and blitter registers will fully work just like on original AMIGA hardware.
All features documented in the Commodore Hardware Reference Manual, work as written there.
Enhancements will be described in similar style and quality.

• PS/2 mouse and keyboard can be used just as well as the original devices.

PS/2 devices are mapped to the original hardware registers.

NATAMI have *NEVER* boasted 100% compatibility.  Given you are using an FPGA to mimic the chipset, you are at BEST, an APPROXIMATION of the chipset.

You can get it *CLOSE*, but if you want 100% compatibility, then use a REAL amiga.

Even Minimig, does not boast 100% compatible, and lets face it, those working on the firmware have done an EXCELLENT job, there are some titles that will *JUST NOT* run, and the same will happen with NATAMI.



It says "Compatible", not 100%.

Like I said, Minimig is Compatible, but not 100%.



SO they have openly admitted there will be some incompatibilities, therefor, not 100%.

I agree with you but different Amiga models used different speeds of ROM/memory, so therefore even an A600 was never 100% cycle exact to say an A1000 or A2000. That why WHDLoad was invented

Can you tell me where Cammy posted this? Did you quote her then change her post when you quoted her to attack Alex? A bit suspicious...

I swear it was there ask Cammy, it leaves 2 choices:
A) Deleted by Cammy herself
B) Deleted by a Moderator

No delusional drugs here buddy
