@marko

nice comparison :)
Now we need also an X1000 bench :)

Sam460 appears to be a good competitor vs the Peg2.

@balis

Yes, those Sam460 numbers are looking pretty good. And those are before any tweaking that may occur in the future.

Very tempting. What is the anticipated release on 460 - wasn't it supposed to be end of November?

@marko

I just noticed that benchmarks on AmigaOne-XE where at 1.4Ghz not on whats common 800Mhz, I have a 1 Ghz version my self.

Sam460 does rally well in all test whit the exception of L1 cache benchmark, way better then I expected or hoped.

Can't wait to see the X1000 benchmarks, I guess depends on getting SMP working.

Basilisk II is slow in window mode, you should have used full screen mode 640x480 or 800x600 in 32bit, you should be able to play some Quick Time movies (16bit is slower), (Maybe graphics does not look the same in full screen as on my computer.)

There are also a number of games that play OK in 8bit.

Probably because of external factors delaying things abit, November has been extended by another 4 weeks or so...

I didn't make the video and it was made on a 1 Ghz board, not on a full speed one.

@gregthecanuck
Yes it was supposed to be available by now. Don't know why it's delayed.

Very nice.

Now, should i post the results of my i7 ?

/me hides

@Speedy

Maybe results of your C=One?

Why not... if it runs OS4... (read title of this thread )

@Crisot

My SamEp 667Mhz, shows MIPs, around 1337. I have read by you, that in order to calculate the raw power in MHz, I have to divide by 3 (that is ~ 446Mhz).

Personally, I believe that this could be the real number, since I feel it way too underpowered and I can't think many other reasons, why all 3D games (except Quake 1) are so chunky (how crappy can be miniGL in AmigaOS at the end?).

In any case, can you please explain me why I have to divide by 3?

Is it possible to make a benchmark that calculates exactly this?

Why U-Boot shows otherwise also?

Have you got any idea why the video bus is so low? What could bottleneck the system so badly?

Sorry for lot of questions :)

What has Minigl common with MIPS of your CPU?

For 440EP it is to divide by 2...

666 MHZ 440EP could be as fast as 500-600 MHz G3 in most applications.

Did you applied latest updates from ACube?

divide by 2. The cpu technical specs indicate 2 DMIPS per MHZ performance.

compare against intel i7 which is 23.75 DMIPS per MHZ. ( x11.87 more powerful)

I'll try to explain...

A CPU is composed of differents units.
-Some units dedicated to simple integer maths (+, -).
-Some units dedicated to complexes integer maths (*, / ).
-Some units dedicated to floating points maths (simple or complex).
-Many other units (memory, branch, etc...).

If code is correctly written, all thoses units are able to work in parrallel, but it's also depending from a last unit, the "dispatch unit".

The dispatch unit "read the code" and send the correct instruction to the correct unit (simple, complex, float, etc...), but it is limited by its own working speed.

On a G4, the dispatch unit is able to dispatch 3 instructions per cycle. You CAN'T execute more than 3 instructions per cycles, even if you have "sleeping" units waiting for work (A PowerPC got much more than 3 units).

So if your frequency is 1000 Mhz, you can reach 3000 MIPS.

The PPC440 (and also PPC460 and G3), are only able to dispatch 2 instructions per cycles, so result is frequency x2. Your 666.666 Mhz SAM can reach up to 1333.333 MIPS.



If you feel your Sam a bit slow, that's unfortunately because Warp3D/MiniGL have to be replaced. Fortunately, Galium is coming. Wasted CPU power is really noticeable on a PPC440.



'Hope I was clear enough

Comparison A1 G3 with 512 MB ram and SAM 460ex with 2 MB DDR2 ram.

I am told that according to Max Treteme of ACube and Hans De Ruiter who is working on the Radeon driver, the 460 values from ragemem are a bit low due to WIP status. I have only just learned of this thread.

Except for the small L2 cache the SAM460 appears to have a considerable edge on the A1 all the way. I'm not quite certain what the video bus is measuring.

@NoelFuller

The write to L2 and RAM is the same on the 460 suggests it has some form of write-through enabled so that everything written is always flushed directly to RAM at the same time. That may not need to be the case in the final version.

The 460 may end up improved if they can get the FSB to 200MHz. Currently it's 166MHz with a cpu multiplier of 7. If it's reliable at 116X (166.x * 7) then it will probably still be stable with an fsb of 200 and a multiplier of 6...I'd even settle for 5.5...

Hopefully a future version of the 460 will be able to handle even faster DDR2 memory.
