Which graphics card is better? 128mb X300 or 64mb 9600 - Page 2

guys, all x300's have dedicated memory... it's the x300SE that uses the hypermemory thing... lol, there wasa huge discussion in this very forum a few weeks back.

Go check out the benchmarks on the X300 in the Dell forums. People with the 128MB X300 can overclock it to get 1700 in 3DMark05. The 64MB version has a performance hit because of the 64-bit memory bus. For the 128MB version, it should perform the same as the 9600 at the same clockspeeds.

If the X300 uses hypermemory as you say AND the system reports the memory as complete, the only other option is to use a driver to reserve the memory under the operating system. If there is no such process borrowing memory then there is no hypermemory. There is nothing to get around it.

Again, the video card cannot simply access the memory as it wants. It's not how a computer really works.
Ok first, I do not need to be told by you how a computer really works, I am well aware. Second, your statement that a system that uses shared RAM ALWAYS report lesser memory is false.

Intel has a similar setup to hypermemory with the Intel Extreme Graphics 2. When it is set to 64MB shared, it will only take 8MB from windows, and use the rest only as needed. Windows will report only 8MB less than what is actually installed, even though it can and will use up to 64MB of system RAM. When set to 32MB shared, it will take 4MB, 16MB will take 2MB, and 8MB will take 1MB. It only uses the remainder of the RAM as it is needed.

Hypermemory is similar, except that it doesnt take the initial 1/8th amount that is allocated for constant use because it has some dedicated RAM onboard. Therefor it only uses the shared ram, like the Intel, as it is needed.

Just because you don't understand how something works, doesn't mean that it doesn't work.

We're talking about the Mobility X300, which does use hypermemory. Look it up on ATI's website.

oh sorry, my bad, the mobility x300 does, but the regular desktop x300 doesn't use hypermemory (that's only the x300SE desktop card that does). I thought it was that the only one that used hypermem was the x300SE.

No problem, I didn't know they did either until I looked it up on ATI's website.

Big claim!

In the first place, all what you said confirms what I said earlier. You can't borrow memory so you need to either reserve it at startup or to use discrete memory (hypermemory). The rest is allocated by the driver under the operating system. If the memory isn't reserved at startup and there is no process allocating it, then the chip cannot use system memory.

Besides, I know how computers work. I may not know all about them, but I know enough to invent a new kind of hard drive, memory, infrastrcture... enough to build a laptop that is 20 times faster and requieres no active cooling. And at half of the price.

I CREATE the technology you can barely understand.

as per this website http://www.overclockers.co.nz/ocnz/r...tepciex3000103

ATi's X300 series VPU is the most affordable PCI-E solution on the market right now, apart from Nvidia's FX6200 which is yet to be seen in the retail market. The X300 VPU is made with the most advance technology on the market, 0.11 micron process. (the previous models were using 0.13 micron) The new process should keep the cost of the VPU down and increase its overclock potential.

"There are two versions of X300 and X300SE. The X300 has a full 128bit memory path, whereas X300SE only has 64bit. (I am guessing that manufacturers may also down tune the engine and memory clocks on the X300SE."

I misspoke when I said that the OS has nothing to do with it, because yes if it is not reserved then yes the driver will allocate the RAM, HOWEVER you cant just look at the list of processes for something using 64MB of RAM, it just wont work. It will only be using the RAM when needed, which unless playing a game or running 3DMark it wont need it.

I never said you don't know how computers work, I just said that just because you don't understand how something works, it doesn't mean that it doesn't. There is a difference. It is right there on ATI's website that the mobility X300 uses hypermemory, yet you say you have seen no proof that it does.

It always amazes me how people like you on the forums assume that you know more than another person because of your job, yet you have absolutely no idea what I do. I have also noticed that people that spout off what there job is, are usually full of BS.

It's obvios that you and I are not going to agree on this subject, so why don't we just stop now. If you are still intent on proving me wrong, may I suggest contacting ATI and asking them.

main stream graphic cards isn't my expertise, but from what I have learned on them so far, ATi makes a chip and nothing but the chip, then they sell them to notebook manufactures who decide how it will be setup, what memory it will use, how much memory it will use, and if it is dedicated or shared.

I don't see how ATi could tell you weather or not its hyper or dedicated. As for nvidia they seem a little more regulated and anything under a 6600 is hypermemory.


btw im a Rocket Scientist!

but im just trying to keep a interesting debate going, i read 6 months a go all x300s would use hypermemory :P

You started being offensive not me. But yes, peace.
