Does a 512mB Dedicated ATI Radeon X1600 exist in a 15.4" or less laptop?

Does a Radeon X1600 with 512mB of dedicated memory exist on a 15.4" or less laptop? I'd like to know, because i want something with 512mB of dedicated memory, so im leaning to the 7600GO in the Asus A8JM laptop for now until i can find a laptop with a 512mB dedicated X1600. Any ideas on which laptop has this technology?

 

Why wait? It's not like there is an advantage to an extra 256mb as I understand it

 

yea...theres probably zero advantage to the extra 256mb ram...

 

Yeah, the X1600 will not fully use 512mb of VRAM.

the 256mb version is really good.

The 7600 cannot use the 512mb of dedicated, it is too slow.

 

So there is no difference between an X1600 or a 7600 with 256mb of ram compared to 512mb of ram? So whats the point? Not even SLIGHT? Then i might as well take an ATI radeon X1600 256mb over a geforce 7600go 512mb.

 

The cards are just not fast enough to take advantage of the extra memory. On high end desktop parts then 512mb will give you an advantage, but on mid range cards then the effect just won't be seen. In extreme situations (ie 1600x1200 with full AA and AF) then the difference will be there, but then it'll be a case of 5fps versus 10fps anyway.

 

The thing is, most games won't even need the extra 256MB of dedicated memory, they'll probably use less than 256MB. There are exceptions, such as Quake 4 & Doom 3 on Ultra mode.

 

The x1600 and the 7600 just aren't fast enough to use 512MB of vRAM as others have said. I won't go so far as to say that games don't use 512MB of vRAM, because as Chaz said, there are a few exceptions, and more usually always helps. But mid-range cards with 512MB are usually rather pointless. As for the x1600 vs. the Go7600, I'm more of an nVidia guy, so I would say go with the Go7600. They tend to be stronger performers in the OpenGL games, and they are much stronger in Linux. But the Asus W3J is one very sexy machine.

 

Alright, thanks, ill probably go with the 512mB 7600 though, since the A8JM seems the best bang for the money. Otherwise, Ill see what suits me well and take the GPU that comes with it. I think ASUS is my brand Thanks a bunch

 

youd be much better off with 2 gigs or more of system ram than 512 video, and on a 15.4" screen, your not going to be playing at near enough resolution to take advantage of it, if you intend to hook it up to a 24" or larger lcd for gaming, then it could come in handy, regardless, the money would be better spent towards other components

 

Even then, a 7600 is still far to slow a chipset to take advantage of 512 MB of onboard memory. Putting lots of RAM on a midrange GPU is purely a marketing tactic to make people think that simply more RAM = better.

 

Exactly, it might, might, use a little over 256mb if your playing a very demanding game and have AF and AA enabled. But definetly not the full 512mb, for that, your gonna need at least a 7900 with a 512-bit bus.

 

See, i dont see any difference between the cards and memory as far as price goes. Its just, i know the ATi Radeon X1600 has a slight edge over the 7600, but if the 512mb on the 7600 makes it up for the 256mb on the radeon, then ill go with the nvidia. If theres no difference AT ALL, all take the cheapest one

 

i'd rethink your methodology of cheapest is best..i think the adagy is buy the most you can afford..i mean if i were to buy the cheapest i would have bought a dell..but i bought a w3j since i like the keyboard..compares very well to thinkpads..and the only one with a fully clocked x1600 in a 14" package that is available in the US

 

This is exactly what we've been (repeatedly) trying to tell you. There will be no difference between a 256 MB X1600 and a 512 MB 7600. The only time there will be a difference is if you're running games at a high resolution (> 1600x1200) and at that point, the 7600 chipset itself is too slow to even run games that high. Thus, buy whatever laptop is cheaper and spend the extra money on a faster CPU, more RAM, and hard drive space.

 

Here's a great post on the topic that may help you out some:

Thanks a bunch

One last thing, should i stay away from Hypermemory/Turbocache? I read somewhere that it takes the ram away from your 1gb or 2gb of ram, and I dont want that to happen, since there will be no difference between 256 and 512.

 

That's exactly what it does. The nVidia's Turbocache is said to be much better at pulling it off than the ATI Hypermemory. Either way, I'm not very high on the concept of either.

 

Its not that much better at all, and any type of system borrowing RAM system sucks.

 

The X1600 slightly pwns the 7600.

Plus.. X1600 sounds way cooler than 7600 XD

 

Here's a little quote from Chaz on the VRAM and Hypermemory/Turbocache discussion pared down to the relevant sections. I do agree, however, that shared memory is a poor system...but that is getting away from the OP's question.
