[EXPreview] Small Review for Radeon HD 7950 Surfaced - Page 6

Although we don't have proof until review I am with you. Center fan version look reference with a custom vendor shroud on the outside. Cooler looks weak to me, no vrm cooling. Might not be needed I guess. I want some reviews.

Even if it is the same power as a GTX580 1.5 card I guess you get GTX580 3GB performance for less? Waiting for more competition to help with prices...

Huh? There's a reference one from ASUS, one from PowerColor and one from HIS.

Edit: No, you're right, kind of. There's no such thing as a retail 100% reference design, but most of these are using a reference PCB.

You'll find out in two minutes (probably, generally the NDAs end at 12:00AM EST, and I do believe the NDA ends on the 31st).

Edit: they're already popping up: http://www.techpowerup.com/reviews/AMD/HD_7950/

That is a sorry excuse for a heatsink on a $450-500 video card (going by Newegg prices as of today).

The comparison between the 7950's reference heatsink and the 7970's says it all:

It is apparently one of the 2 reference designs available. Check on newegg, all of the reference 7950s are using this design. The only difference among them is the design of the plastic shroud. I have not yet seen a retail 7950 using the other reference design, probably because it is much more costly to produce.

These are the 2 reference designs for the 7950:

The cooler is actually decent and can dissipate a good load. It cooled the 4890 at low noise levels. No vrm cooling is not a good sign for the overclockability of the 7950 though.

The Vapor-X cards had heatpipes, larger aluminum fins, and a separate VRM heatsink. A VRM heatsink might not be necessary for this card at stock, but I would think you would want something once you flash and OC.

I think that's a typo on the reviewer's part. The cooler is from the 6950 he compares the card too. It wouldn't make much sense to have a bare 7970 lying around only to use a 6950 for the PCB comparison. The 7970's aluminum heatsink outlines the front of the card and is more rounded.

Hardware canucks had both cards. They were sent a 7950 that was probably a 7970 with diff bios for testing. Just before the reviews came out they were sent a center fan reference card. Because of the low power draw it seems to work, but for that price they could give us a little better cooling, vrm, etc.
