XFX - Radeon HD6570 1GB DDR3 weaker?

[Mimishiki19]

I'm looking to buy a xfx radeon hd 6570 1gb ddr3.Code is HD-657X-ZLF2
Here's the link

It's in romanian so here's a newegg

My question:
Is the XFX model weaker/slower than a normal 6570?
I've read a review on game-debate that said this model is 64bit instead of 128bit and other stuff that don't match the specs I found on other sites.

I know it's low end card but it's very cheap 200ron compared to the 6670 which is around 260-300 ron.
I have a GeForce 8400 GS so it would be a improvement.

there are 64 and 128 versions. both you posted are 128.

Sorry.My mind is in the clouds.Meant to post the link but forgot

The model he's reviewing is the 128bit one if you look at the specs but the memory speed is 650 when it should be 900.Also the card I'm buying doesn't mention the speed.It says 650/1300 but I've no idea what that means.

Another question:
Is this XFX model better or worse than a GT 630?

AMD Radeon HD 6570
Average G3D Mark - 754

GeForce GT 630
Average G3D Mark - 722
http://www.videocardbenchmark.net/gpu.php?gpu=GeForce+GT+630

Higher results represent better performance

the faster the core the faster the card will be overall. ( 650 ) if it was 670 or 700 or 800............ the higher the number the faster the card.
the 1300 is the memory speed.
i never used a 630 so I can't answer that.

The reason is probably because those are DDR3 cards not the faster GDDR5 memory cards
