Nintendo Switch (Nintendo NX) release date, price, specs and preview trailer: Codename NX console…
I have the Radeon X800 Pro graphics card with 256 mb of video memory however after running 3D Mark 05 last night I noticed that I only have 128 Mb of AGP memory!
I think it's still there as in my screenshot I have 256 Mb displayed by the side of the following 2 entries: 'Total Local Video Memory' and 'Total Local Texture Memory'.
What's the difference between the above 2 types of memory and AGP memory?
I thought that video RAM was all the same?
Also why is there a difference in the memory size for AGP?
Thanks for the link but what I mean is that I hadn't heard of 'Total Local Video Memory' and 'Total Local Texture Memory' before and was just wondering why these RAM totals were double the size of the AGP memory total?
It's not that important as my graphics card is in perfect working order but I was just a little surprised by this that's all! ;0)
I will tick this as resolved as I have done a bit of Googling and have come to the conclusion that everything is in order as below is an actual post of someone's specs on a forum and they too have the same RAM sizes as me on each of the 3 different memory types.

I have added the * to make it a bit easier to read.
The 128MB is referring to the BIOS setting for system memory reserved for use by the AGP bus.It doesn't refer to the actual physical memory of the graphics card(thats the other two figures you mention)which is correct at 256MB.
Don't worry that there are two different settings...your system is fine as it is.click here for a brief explaination of the AGP memory size.
Just found out the solution click here and scroll down to the article "Doesn't add up" just over half way down the page.
In the article it mentions that:
"You won't, however, necessarily see the right number when you look at the info display in 3DMark, or in other utilities like Nvidia's AGP memory display application. Your AGP aperture probably is set correctly but graphics card drivers often can't figure out the right value, and deliver some semi-random number. Sometimes the reported value is zero bytes.
Don't worry about it, though. If it's wrong, it's just a cosmetic problem."
The mystery is solved!
Interesting link. Thanks.
