Hi all,

Well Ive just had a play with the new 1200, and ran a copy of
Sysinfo v3.01 on it too see what it can do!

The 68020 is running at 15.2 Mhz, this model with 2 meg CHip ram and no
fst ram.

Drystones ;- 1296
A1200 = 2.2 times faster than A500
1.85 times faster than A500 with Fast Ram
0.63 times A2500 with 68020 (14Mhz) !!!!!!!! Why????
0.28 times A3000.

Giving 1.35 Mips

Is it impressive. ? Im not so sure rerally really.

I should imagine I will get one, but it isnt really a great increse in
CPU power.

Ant.

I'd bet that your results would be much better on a machine with some Fast
RAM. I ran the same version of SysInfo on my A3000 with the FastMem both
on and off and the results are interesting.

My times are below the originals in with/without FastMem format.

Well, if you consider that it has no Fast RAM, it is quite impressive. In
fact, it is than a 25MHz A3000 with no Fast RAM. While I'm not certain that
the addition of Fast RAM would have the same impact that it does on the A3000,
I'd bet that the numbers would increase.

The funny thing is that the 14MHz EC020 in the A1200 is faster than the 25MHz
030 in the A3000 when both are running with Chip RAM only! All I can guess is
that the AGA chipset is tying the bus up even less than the ECS chipset, which
is what C= has been telling us all along.

>I should imagine I will get one, but it isnt really a great increse in

A bit of Fast RAM will probably do a lot of good. The AGA chipset will also
go a long way towards making the machine much more powerful than any other
Amiga with the exception of the A4000 and possibly other AGA machines. Sure,
the A1200 may have a few faults, but overall I like it and think that C= has
a potential top-seller if they will market it.

What if Commodore had introduced an A1200 type machine that had an EC030,
SCSI, and the ECS chipset? The cost of the 030 and SCSI should more than
offset the savings of not using AGA and the resulting price might have been
similar. Would people have really wanted something like this? I don't think
so, but the amount of whining about the A1200 is almost as bad as that about
the A4000. What in the world do people expect?

This seems to be awfull! I would assume that an 68000 based Amiga
running at 15.2MHz would give double the speed of an A500. But the
A1200 has an 68020.... that should at least triple the speed
compared to the A500.

What speed is the chip mem going at? Maybe the chip mem runs at the
original A500 speed, slowing everything down. That way you might get
the real speed increase with some Fast RAM.

If I run nofastmem on the A3000 and use SysInfo 3.01 it tells me the
speed is 2.48 times faster than an A500 and Dhrystones = 1459. Gee, not
a fast machine.... :) (Although exec and libraries are still in fastmem
because it's not a true chipmem only test)

You can't measure the best performance of the A1200 with only ChipMem
and sysinfo, you really need some fastmem. The speed should be (I say
should 'cause I ain't got one) around five times faster than an A500
with A1200 fast memory, and instruction cache turned on. If the ROM is 32bit
wide, then there is no need for CPU FastROM either.

Regards,
Stephen.

This is exactly what one would suspect, since CHIP RAM is still
at 7.14 Mhz, but add some FAST ram in the slot on the bottom
and it will be faster than an A2500/20 by a lot.
FAST RAM in the trapdoor slot runs at full processor speed,
with all caches enabled. I think that inst cache works
better out of fast RAM. In any case to get real performance
with an A1200, some fast ram will be needed. This is not
a bad thing, it is MUCH faster than an A500/600 as shipped,
but the gains from adding fast ram on an a1200 are MUCH
greater than they were from adding fast ram to an A500/600

No...SysInfo says its running at 15.2 MHz...the actual clock is 14.28 MHz
(approx).

Well...I'd be real careful about basing a decision on this data. SysInfo's
test are extremely simplistic, and not really showing of much of anything
in terms of real performance. In addition, it has been known to be very
wrong on more than one occasion.

that's 14.28 unless you've fudged something...

Add fast memory and try again. (yes, I know you can't do instantaneously)

Also, try the tests when displaying the display modes that really slowed
down the chip memory only A500. 4-bitplane hi-res, etc...

Why? Probably because an A1200 has no stock Fast Ram. If you add Fast Ram,
your system performance would be GREATLY enhanced.

Without 32-bit FAST RAM you will not see the major speed improvement since
the only speed you are seeing is the 32-bit CHIP RAM speed increase.
The CHIP RAM timing is still the same as it was (7.xxx MHz) but it is now
32-bit vs 16-bit on the A500/A2000/A2500. The A2500 has 2megs (minimum) of
32-bit RAM. With some 32-bit RAM for the A1200 you will see speeds that
will equal or better the A2500 in all cases. (Unless the RAM is of a
bad design, in which case, well... you get the picture.)

Well, except that it easily beat en A2500 whan you're out of fastmem.
I tried some benchmark on mine after I read this and Sysinfo reported 0.87
of an A2000 with fastmem!!!!

I also tried to run som test on AIBB with only chipmem.
As long as one use the overlay function so that the custom chips don't steal
DMA then performance is not so bad, but try to turn this of and performance
will fall 6 feets below ground...:(

I suppose that the performance on the A1200, if the above numbers is
representative (I don't like Sysinfo), is really quite good if you put
it up against an A2500.

Probaly as it only has chip ram and no 32 bit fast ram

With a 14 MHz 68020, 120nS ROM's can run zero-wait state accesses,
so DRAM can't be any faster (effectively). For a faster processor,
or an '030 DRAM may be faster, though some of the FLASH memory
chips are offering some pretty fast timings.

Just moving the system stack to fast ram should make a big difference.

The folks on this net expect to get the best, fastest, newest technology in a
laptop package for under $500 - no, that is too expensive, make that price $1.

68040 at 50 Mhz. (or 100 Mhz Alpha or...)
fast Gigabyte hard drive (or three)
CD-ROM jukebox
DAT
DSP
2048x2048x24 display
at least 20 Meg ultra fast static RAM
8 Meg ultra fast CHIP RAM
20 Meg Floptical drive
5.25" HD drive
emulation mode that runs ALL software for ALL computers faster than the original
computer

and free software and hardware updates for life.


Oh, yes. Don't forget, we don't want to hear any more silly whining from those
engineers who keep saying that it is not feasible, costs too much to build, etc.
Ask MB, he can tell you how to do it!


P.S. For the humor impaired... 8^)

There is no way I would fork out $1 for a computer without an external keyboard!
