Apple just released a Mac OS X 10.4.8 developer seed marked as build 8L2112 (Intel) and 8L112 (PPC). This latest build was released to developers with little fan fare.

An unconfirmed post claimed the latest 10.4.8 build did incorporate enhanced OpenGL performance which led to the following Cinebench that does not show significant improvements:

Update: Apologies, it appears the benchmarks are not significantly better. Updated numbers seen. Improvements may have been gradual over 10.4.x updates or simply variability in the benchamrks

can someone with a Macbook Pro 2.16, 2GB RAM, Mac OS X 10.4.7 run cinebench and post their results?

What does this mean for PPC users such as myself?
It means if you have a multi-core or multi-processor Mac, then you will see similar speed benefits.

Remember that multi-core/multi-processor PowerPC macs where limited to PowerMacs, however.

while these are impressive speed increases, i am not sure how impressive it would be in real life. does any part of the native os x gui or core elements use OpenGL?

the real question is would this increase the "snappyness"' :D of the next release?

Let me try not to die from the laughter.

Oh and yes you're going to see a performance increase on integrated graphics systems with multiple-cores.

Well, guess my iBook G4 and in-the-mail Clamshell, PPC mini, and 12" PB G4 are left out of this party.

Am I reading that correctly to say its a 4x to 7x improvement?

Thats staggering.
No, it's a 2x improvement if anything. I still need someone to run it on a latest 10.4.7 Mac Book Pro with 2.16GHz CPU and 2GB of ram if possible to verify results.

edit: MacBook Pro

Are you looking for a MacBook or a MacBook Pro? I don't think there is a 2.16 GHz MacBook

I really hope this update will double the graphics performance of my dual G4 PowerMac. Ideally games will not have to be updated to take advantage of 10.4.8's Open GL improvements.

The way blizzard is talking, yes they do have to be updated.

Certainly looks like it's there, almost exactly 2x everything. Very cool, since OpenGL is used just about everywhere. Things are looking up for my hopefully imminent MB/MBP purchase in Jan/Feb maybe. Will Vista have multithreaded OpenGL or anything similar (is DirectX multithreaded)?

I got some strange results from another MacBook Pro benchmark

2.0GHz, 2GB RAM, 10.4.7:

Rendering (Single CPU): 300 CB-CPU
Rendering (Multiple CPU): 569 CB-CPU

Multiprocessor Speedup: 1.90

Shading (CINEMA 4D) : 342 CB-GFX
Shading (OpenGL Software Lighting) : 1288 CB-GFX
Shading (OpenGL Hardware Lighting) : 2339 CB-GFX

OpenGL Speedup: 6.84
Still not as fast as the 10.4.8 #s, but not that bad. Until I see some more benchs, I pulled the story off the front page. Need more benchmarks...

DirectX has had it for awhile.

Some code modification is reportedly required to see the full benefits of the multi-threaded OpenGL.
Hopefully it will just be a simple small download patch rather than a complete rewrite. Hopefully this OpenGL speedup will encourage more native Mac game development.

Yeah, from what I can tell World of Warcraft already has some of the stuff put in, if not all. And is just sitting idle untill OpenGL is patched.

Blizzard pushing on Apple for help to make WoW faster is part of the reason these large OpenGL changes are coming along.

Just for fun here are my Cinebench frm 10.4.7

CINEBENCH 9.5

Results

Hi there,

My first post, with results.

Cinebench ran on MacBook Pro 15" 2.16GHz, 2GB Ram, X1600 256mb card, with OS X 10.4.7:

CPU (1 CPU): 329CB
CPU (2 CPU): 626CB
Multiprocessor Speedup: 1.90x

C4D Shading: 385CB
OpenGL SW-L: 1476 CB
OpenGL HW-L: 2828 CB
OpenGL Speedup: 7.35x

Double-checked results, they are accurate. It would appear that your results for 10.4.7 are pretty inaccurate. The real gain is practically negligible. Also, note that I'm running the MacBook on clamshell mode connected to a 30 ACD, so I'm pretty sure the number of pixels powered influences the results a bit.

Later,
M.

ok...

I suppose there have been speed increases along the way from the first 10.4.x results that where posted.

So, no substantial increase in speed I suppose. Also, I verified that the Multicore OpenGL speedups do require code modification, so it's unlikely to be the cause of any significant speed up on these benchmarks.

thanks. will update to a Page 2 story. Sorry for the false alarm.
