So looking a the new macbook pro's configurations, I see that the 9600M GT is offered as either 256MB on the 2.43Ghz model, and 512MB on the 2.53Ghz model. I cant find any benchmarks related to this GPU comparison, so I'll ask you guys: Is the 512MB version going to make a significant difference in performance (gaming) as opposed to the 256MB?

Many new games use 512MB+ VRAM... Heck some even use more than 1024MB.
 
The 9600 (same as 8600 and 9700) is 128 bit, meaning it can only use up to 256 mb of vram. Meaning the 512 is no better. The only way it would be better is if it were a 256 bit card, so it could use 512 mb vram. But its not. Save your money. ;)

How can you relate Memory Controller Width with Memory amount? The correct phrase should have been yes, to get all 512MB you have to use higher settings in games, but since it's GPU is not powerful enough to process those higher settings virtually 512MB would be overkill. 9800M GTX could have taken advantage of the extra RAM but not 9600.

Yet I believe that 512MB could be useful in not Graphics intensive but texture intensive games lie MMORPGs
 
interesting, so what benefit does the 512mb have over the 256mb if that difference cant even be used?

it can be used, but to use it you have to hike the eye candy stuff in games. But that result greater processing power from the GPU and 9600 might not be powerful enough to process those eye candy effects to use all the 512MB.

But again, texture intensive games could benefit from the extra 512MB since texture drawing is not as much of a load on GPU as let's say particles or shading.
 
Here's a relatively simple explanation I found on another forum talking about the 128-bit 8600gt 256mb vs 512mb:

Allow me to put it in layman terms.

Think of the memory bus as a street. The 64 bit is a 4 Lane highway while the 128 bit is an 8 lane highway. Logically, the 8 lane highway can handle twice the number of vehicle compared to the 4 lane highway. Translate this to memory bus will means that theorically, a 128bit memory bus can handle twice the amount of data compared to a 64bit memory bus.

As for how much memory is enough, let's take it this way;

For example, I have a carpark that have 256 parking slot and a 128 lane road that can only handle about 256 vehicle traveling in and out of the carpark at any one time. So if I were to increase the number of parking slot available to 512, will it increase the rate at which the the car will go in and out of the carpark via the 128 lane of road? Logically , theorically and practically, the answer is no.

Now let's put it in into your question: "So with the 256MB vs 512MB in subject, any proof to support your claim?"

Your graphic card have a video memory of 256MB and a 128bit memory bus that can only handle about 256MB of data transferring from the GPU to the VRAM at any one time. So if I were to increase the amount of video memory available to 512MB, will it increase the rate at which the data will be transfered in and out of the GPU and the VRAM via the 128bit memory bus? Logically , theorically and practically, the answer is once again no.

So to conclude, there's actually not much difference in terms of performance when comparing a 512MB VRAM and a 256MB VRAM variant of 8600M GT.

Hope my explaination have persuaded you in letting you know the rough idea what are all this about. If you still need concrete proof, feel free to post here. I'll try my best to answer your questions.

OT: Recently just realized my Acer's 8600M GT is manufactured by MSI.

Apparently there will be no noticeable difference.
 
hmmm I see. so you make it sound like the difference isnt that outstanding to merit the price difference. what about the gpu relevant to the cpu. does the 6mb cache, paired with the 512mb worth the $500 price difference? It just seems like alot of money for perhaps a slight performance increase, or maybe im wrong?

The performance increase would be slight that's for sure, but the gap could widen in texture intensive games.

Graphics cards use System RAM if the VRAM is full. VRAM is used to store vectoral and graphical information. if it's full, GPU takes some of the System RAM to store informantion, whcih sig drastically slower than VRAM.

500 USD difference is not only 256MB more of VRAM, you get a faster CPU with more L2 cache. But if you're not a serious gamer, you would be better off with 256MB
 
good point, but I guess the age old question arises here. Spend the money on the 6MB L2 processor, or save the difference and use it on more RAM. Which would be the better performance gain relative to $$ spent be
 
The memory controller being 128bit has nothing to do with the amount of memory that the GPU can handle, only the throughput speed of that memory. More VRAM can still be beneficial--it simply depends on the game and the design philosophy behind the game. Some games, like Crysis, are almost entirely dependent upon GPU memory speed/throughput--that's why one needs something insane like a 384bit memory bus with the highest possible rated (>1GHz, 100+ GB/sec bandwidth) DDR3 memory to play it on 'ultra-pretty' mode. Other games rely less on constantly moving as much data to the GPU as possible and instead try to make things prettier by using higher resolution textures.
 
The 9600 (same as 8600 and 9700) is 128 bit, meaning it can only use up to 256 mb of vram. Meaning the 512 is no better. The only way it would be better is if it were a 256 bit card, so it could use 512 mb vram. But its not. Save your money. ;)

Disregard that post. It depends whether or not the applications you run can take advantage of that memory (framebuffer for textures etc). Memory bandwidth has nothing to do with that.
 
I ordered the one with 512MB and I think it'll be great. Even if it's not a huge improvement over 256 it's still more. More is always better than less in terms of memory (if the other specs is the same of course). I'll probably be running the 9400M most of the time because it's enough to play my precious WC3. :rolleyes: Hopefully 9600M will be enough for some RA3, SC2 and D3.

But the main reasons I went with the "bigger" model is due to the 4GB of system memory, bigger L2 cache and larger hard drive.

However, the Swedish Apple store said "7 days until shipment". :( Can't wait! :D

Anyone else want to make a statement about that? I also just read that the 9600M can't run Crisis unless it's on lowest settings, but can run "current games" on mid - high settings. :confused:
 
aHH Help

Ok. So I have been looking around.. LOts!

Can't seem to find the info I need. Right now I take advantage of the majority of the CS3 suite. I use it on a Macbook 2.0 2GB with the 64mb integrated graphics. It chugs quite a bit. Especially if I have more than one app open at a time.

Planning on getting a new Macbook Pro. However I am trying to decide if the extra for the 512MB graphics is worth it? or will 256mb suffice? In the long run obviously the 512 will be better. I run my computer with external monitors. Which I'm sure takes a small toll on it too.

So for the CS4, do I choose 256 or 512? Keep in mind I will probably have 2-3 CS apps open at once.

Help? or direct me to where I can find the info?

I'll try and help. I got the 2.53 ghz MBP. There's a few reasons I think it's worth it.

1.) if you use an education discount, you get $100 off of the 2.4 ghz but $200 off of the 2.53 ghz
2.) 2.53 comes with 4gb ram
3.) better processor with twice the cache which you can't upgrade later.
4.) bigger hard drive standard.

It actually doesn't end up being a $500 difference if you think about it. Take the 2.4 ghz, add in 4ghz of ddr3 ram and a bigger hd and I believe the price difference ends up being around $200 less.

So the question is, would you like a better processor with twice the cache, bigger hd, twice the ram and twice the VRAM for $200?

Depending on the game, there are performance increases in the 2.53 ghz version. It could be any of the things listed that give the performance increase. Also with higher resolutions (external monitor) you should get better results.
I didn't want to regret it down the road so that's what I did. I also got the 320gb 7200 rpm hd.

Oh, and to the guy that said he read you can only play crysis on low is wrong. I posted all of my settings in another thread which are a mix of medium and high and have pretty good results from that. It is the most demanding game and that's on a laptop.

The 2.4 will be fine. Thats what ive got and been running cs4 beautifully....I have run ps, safari, itunes, and iphoto at once with no problems at all. Also I have run dw and ps simultaneously and not noticed any problems at all.
 
If you have the money get the higher spec model. You're going to have it for a good 2-4 years before you go to replace it so you might as well put down the extra money. We might see advantages with it in snow leopard and CS4 takes advantage of it, specially if you're like me and have several windows open at once.
 
Do bear in mind the higher processor speeds and more processor cache (ie, more transistors) translates to higher temperatures and lower battery life. Also a consideration for many, since the battery capacity was reduced by a significant 10WH.

Personally, I went with the 2.4Ghz and upped the RAM to 4GB - it's user-upgradeable so you can buy it cheaper elsewhere as compared to Apple Online. The HDD does not have to be bought from Apple too, so the cost savings are potentially higher, plus you get an additional drive and RAM modules to use as spare/external.

HTH.
 
you guy just made me regret that i ordered the 2.53 model.. despite the "slight" increase..
party breakers.
now im in a bad mood.

I have the previous generation MBP 2.5GhZ. I went for the 6mb cache because that is not upgradeable after market like RAM is.

Get the better processor and upgrade RAM later, if needed.
 
I guess the best way to think about if its worth it is to think 'what else can I do with that $500?'

Buy an Xbox or PS3 maybe? A new surround sound system would bring me a lot more joy than a 10% increase in the frame rate...

I think I'll go for the 256 after reading all this and looking at the benchmarks...
