So LinusTechTips claims 6990 has 4GB memory

post #1 of 42
Thread Starter 

The video in question is this:


He says that the card has 4GB of ram and forgets to state that only 2GB of it is usable.

I believe he doesn't know what happens when you crossfire. Here's his reply to my message regarding this issue:



The truth is the card does not have 4GB. Yes 4GB of memory chips are present on the PCB but since memory is mirrored (there's same data on both 2GB sets) the actual usable memory size on the whole card is only 2GB. Apparently some "enthusiasts" like Linus himself doesn't know that.

Also GTX 590 does not have 3GB but 1.5GB usable ram.

I think he also falls for so-called "512 bit" argument which is also false because same thing applies here. It's 256 bit not 512. These things were made up for marketing by AMD/NVIDIA. Very unethical.

You're bent outta shape over this? He's technically right though, there is 4gb of vram on the card! How the card uses it is different, but doesn't change the technical facts. He's a kid doing box openings for a big shop right?

yes that's what he does.

and i don't agree with you on that. what you said is the same as buying a 500GB hdd and finding out when you get home that for some "technical reason" only 250GB of it is usable and manufacturer *oddly* never mentions that neither on the box nor in their product webpage.

Ummm that is exactly the way it is in real life......

HD manufactures use 1000 kilobytes to a meg
While computers count it as 1024 to a meg
So you get way less space on a HD then advertised.
I dont really know or care... but if the ram runs in lockstep then yes there is actually twice as much ram there. Just cause "you" cant use it doesn't mean it isn't there. The card still needs it to function.
LOL

NO.

Hard drive manufacturers acknowledge it and state that openly so that's a known fact. You can even read that info on the sticker of most HDDs.

And even that does not make big difference between marketed HDD capacity and actual HDD capacity.

250GB(marketed)-232GB (usable)
500GB(marketed)-465GB (usable)
etc...

What i'm talking about here is the half of the memory size on a graphics card! Cutting it in half. And unlike HDD manufacturers, AMD/NVIDIA do not state this openly, it can even be said that they try to hide this info.
