SAM 460 poor performance, high price

[Louis Dias]

Really? What are you basing this on?

The numbers I've seen are:

SAM460 AMCC460 1.167GHz

Code: [Select]

---> RAM <---
READ32: 311 MB/Sec
READ64: 310 MB/Sec
WRITE32: 521 MB/Sec
WRITE64: 521 MB/Sec
WRITE: 1251 MB/Sec (Tricky)

Mac Mini 7447 1.5GHz

Code: [Select]

---> RAM <---
READ32: 387 MB/Sec
READ64: 403 MB/Sec
WRITE32: 771 MB/Sec
WRITE64: 771 MB/Sec
WRITE: 809 MB/Sec (Tricky)

By your own listing there, the last write speed listed was 50% higher probably because it involves writing to main ram.  If these tests were performed using local cache then the Mac will win.  Writing to actually RAM and reading from actual ram should be faster on the SAM as someone else posted earlier.

Anyone can make a test that is more favorable to one platform or the other.

I'll wait for some real world benchmarks.
The fact of the matter is it will talk faster to the gpu, like it or not.  SAM460 will *feel* faster than it's 1.15MHz.

SAM
---> VIDEO BUS <---
READ: 72 MB/Sec
WRITE: 261 MB/Sec

MAC
---> VIDEO BUS <---
READ: 32 MB/Sec
WRITE: 180 MB/Sec

Even your posting was biased...sad...

dont forget the video ram numbers too

I think you are wrong. The Mac will actually be faster in real world use and fell faster due to MoprhOS being a quicker OS than AOS4.
 
I go into troll mode with you when I get bored of your views which you dont ever back up with actual evidence. And jsut to remind myself and other people the rubbish you are capable of coming up with.
 
The Mac Mini video bus is the weak link.   But thats not an issue on other macs.

Better yet, Quake III and Blender benchmarks for real life speed.

So you finally admit being a troll.  Quoted for accuracy.

The bottomline is I have actual hardware and software experience.  I am employed in a technical position.  I've been an IT admin and am currently a developer.  I did take courses in Computer Engineering.  People like you can understand simple concepts.

Fact: Quake3 will run faster on a SAM460 than on a G4 and that is directly because of video card performance.  Please return to your bridge.

Despite the updated PCI bus drivers on SAM440, it did not improve Quake 3 there.  Quake 3 loads everything it needs into the gpu at the start of the level.  The gpu is the limiting factor in games using 3D like that.  Sam460 supports faster gpus than are possible on Macs and Sam440.

People like me can understand simple concepts.   Just as well I am not a programmer for a living then., oh wait there, thats what I do

Then counter with reasonable arguments instead of trolling...

All of these tests go to main memory. There are separate tests to L1 and L2 caches. Ask Crisot for details.

This test was created by Crisot, OS4 user. The test was run on SAM460 by OS4 beta tester. Sure you could blame me for trying to use my mind control powers to affect these people but you give me way too much credit.

Even your posting was biased...sad.

Pot, kettle.

Here is my view.
I don't care what OS SAM460 is running.
SAM460 will run 3D intensive games better than any Mac regardless of what OS is on the Mac.

Nothing is stopping you from porting to it.  Instead you make it an OS issue of AOS4 vs. MOS.  It's old already.

My 2009 MacPro would like a word with you...

Oh?  I guess you forget that we are still on planet PPC in Amigaland...

I think what matters the most is what you have available today. With currently available drivers MorphOS 3D runs circles around this sam460.

By time time some sort of 3D support will be available for Sam460 MorphOS might have new 3D drivers released. They already run quake3 150fps on puny Radeon 9200.

I won't even bother splitting hairs about using PCIE<->PCI bridge and all that nonsense which might allow Macs to use some yet unknown future gfxcard.

@lou_dias

So any comment on as to why this Sam460 with supposedly superior memory bus loses to 6+ year old Mac mini G4? Or did we change the subject already?

The SAM460 already outperforms a G4 1.5Ghz on large memory intensive tasks.

So again, what are you basing this claim on? Or did you just assume something here without actually checking?

If a bridge is still limited to PCI speeds.  I'm glad you are basing Mac power on this 'magic bridge'...
