I was quickly looking at the review and noticed that the 7770 as less stream processors than the 6770.....this seems weird unless the new architechture is that much more efficient.

I also noticed that the 6790 has the same specs compared tot he 6750 but with slower core and mem speed, is this a mis-print?

Barts LE: 800 SPs, 40 TMU, 16 ROPS,
Juniper XT: 800 SPs, 40 TMU, 16 ROPS

There are several architectural differences (tessellation, caching hierarchy, bandwidth, etc) which allows the Barts core to pull ahead regardless of the specification similarities.

less stream, more core speed. In the end, it's (supposed) to balance out.

The 6790 also has a much larger memory bus.

Well that was disappointing. These days you can find 6850's for ~$130 after rebates.

Thanks for the review, Sky!
I have to agree that the prices don't make sense given that the 7770's die would obviously be smaller than the "outgoing" 6850's die. (Horrible amount of 28nm manufacturing issues?)

What happened to the people who launched the Radeon 4850 and 4870 and completely overturned GPU pricing ~3.75 years ago?

How often do consumers actually buy hardware at regular price these days? The seemingly high launch price might just to make the sale price and rebates look better. It may also be reflective of availability.

Most of the time the pricing structure sent to reviewers is fairly accurate I am afraid. We didn't see many dips from launch prices on most products.

Core computer components, and video cards especially are3 one of the only products that actually tend to retail for MORE than the MSRP. Almost everything else is sold for less, even if it's just a couple of dollars. It's a ratehr disquieting trend that has been increasing ove the last couple of years. It also seems more pronoucned with ATI's products. Perhaps due to the reason SKY linked to previously.

Availability? No I call it greed. I recently found a brand new HD 4870 selling for a whopping $412 !

Official Newegg pricing: $159.99 to $179.99.

At least it isn't the retailers gouging this time.....
