go 7400 vs 7600?

How big is the difference? I looked at the 3DMark scores and 7600 was almost double! does that mean that if I have 40fps with the 400 I'll have 80fps with the 600? (I'm a cs source/bf2 player, so I need a good graphics card for that, since I'll be gaming half the day. Also, could someone estimate the fps on cs:s/bf2 for the 400 is I had 2 gigabytes of ram?

Thanks!

 

If you are gaming a lot for sure i would go with the 7600go, I have it and it plays bf2, bf2142, cs source,hl2 very well. And no fps will not double but you will see fairly large gain in fps in the 7600.

 

The Go7600 is roughly twice as powerful as the Go7400. You'll need at least a Go7600, for playing the games you mention at high settings.

 

Yes it does have twice the power, but that doesnt mean you'll get double fps in your games. If you want to play games at high settings though go for the 7600. But if you're fine with medium-ish and want to save some money, go for the 7400.

 

I play BF2 on my Go7400. Get about 50fps at 1024x768, options at medium, view distance 100%. What kills it is enabling dynamic lighting and shadows. which is annoying, as without shadows things look a bit....out of place and just fake, really. But it does the job.

 

so which is better 128M 7600 or 256M 7400 ?

 

the 128M 7600 will be definitely faster

 

No way is the 7400 going to be better than the 7600 even if it has the higher edge in memory. Always consider which one's the newer and better model before you look at the memory. At least 128 mb of dedicated memory will do much already. The go 7600 is without a doubt the better, wiser choice.

 

The 7600 is better, but a 256M 7600 is strongly recommended, for 2 main reasons:
- newer games need large framebuffers
- often the 128M 7600 is a 7600SE with a 64bit bus instead of 128bit (on some Acer and Toshiba for sure, but I don't know if there are other manufacturers that use this version). A 7600SE should score about 2600-2700 on 3DMark05, instead of 3400-3600.

 

the size of dedicated RAM is only essential when the game needs it, if the game doesnt then theres not much difference between a 7600 128, 256 or 512, unless other aspects are toned down or suped up. also system RAM is only going to help in terms of loading times and such things as the system lagging cuz it needs to unload and load more during gaming, but wont really affect the average fps of a game when there is no serious loading to be done. and as mentioned above newer games need larger framebuffers so the less dedicated RAM the less potential power the card will have. a 512 version of a 7600 could be useful in the long run but the 7600 might become redundant by the time 512 becomes the norm for games, so stick with 256 megs for now and the short run

 

Go to meaker's charts and compare the specs.7600 is even more than twice as powerful (the pipelines are are parallel,the bandwidth and memory is not much of bottleneck , many companies use GDDR3 for 7600 whereas all of them (correct me if I am wrong) in the best case use DDR2 for the 7400)

 

Well, actually for mid-range cards the standard ram is still DDR2. Even some 7700 are equipped with DDR2...
There are really few X1600/X1700 and 7600/7700 equipped with GDDR3. If I had GDDR3 on my vga, I could reach 5200 on 3DMark05...
