Synthetics
Because the 7970GE uses the same architecture – and indeed same chip as the 7970 – there’s not much to report here with synthetic performance, but we’ll quickly run through the numbers.
Starting with 3DMark Pixel and Texel Fill, the 7970GE improves on the 7970 around as expected. Pixel fill is a bit low at only 4.5% though, which is unexpected since the 7970GE got a big boost in both its core clock and its memory clock.
Next up is tessellation. While at normal tessellation levels we’re CPU or otherwise throughput limited, at maximum tessellation levels the 7970GE further improves upon the 7970 by 13%, which means we’re likely seeing the full impact of PT Boost in action here. However at this performance level we’re also approaching the same throughput limits we saw with normal tessellation, which means that we either need a better test or GPUs are reaching the point where they have more than enough tessellation performance for future games.
Finally we have Unigine’s Heaven. The GTX 600 series has always done well here, and while the 7970GE improves on the 7970, the GTX 680 is still well ahead for what it’s worth.

the first chart, the regular 7970 is priced higher than the ghz edition. the second chart shows it as lower howeverRyan Smith - Friday, June 22, 2012 - link
Actually those are a list of launch prices up top. The 7970 launched at $550, which is indeed higher than the $500 launch price of the 7970GE.EnerJi - Friday, June 22, 2012 - link
It's confusing and misleading. The first thing I thought when I saw it was that you had accidentally reversed the prices between the two models.Iketh - Friday, June 22, 2012 - link
that certainly isn't what I thought... i understood what was being presented to meCeriseCogburn - Saturday, June 23, 2012 - link
I love how amd has a birthday for tahiti at 6 months....Why wait a year for a birthday when you're a lying sack of crap corporate monster rip off crummy drivers fan boy mass brainwash co ?
Heck, two birthdays a year !!! amd is so great, they get two birthdays a year !

People in the first few months of a relationship like to mention anniversaries a lot despite the (rather obvious) point that the word denotes a yearly period. "Milestone" would be more appropriate though it does sound less glamourous and perhaps a bit pessimistic (well, in the case of relationships, anyway). Might even seem cynical.Captmorgan09 - Friday, June 22, 2012 - link
Just read the chart and it's not confusing... I did a double take the first time I glanced at it, but when I actually read it it made perfect sense. :)Ryan Smith - Friday, June 22, 2012 - link
In case it's not clear, since we have a price comparison chart at the bottom, the purpose of the prices up top is to help describe the cards. The fact that the 7970GE is listed for $500 next to the $550 7970 for example is to make it clear that it's launching at a lower price than the 7970. It helps offer some perspective on capabilities and the market segment it's designed for.That said, we can always get rid of it if it's a problem.

Could I suggest adding when they launched on the line right above the prices? I can easily see how that is confusing, but also knowing how old each generation would be useful to see.Ryan Smith - Friday, June 22, 2012 - link
Now that's an excellent idea!
