There are a few things that need to be set straight with the ravings of both sides.
- Southern Islands IS a huge step in the right direction for AMD. The architecture is efficient, performs well and is massively impressive regardless of what NVIDIA fans say while burying their heads in the sand.
- Here's a shocker for you: AMD is behind the technology curve. Sure Tahiti is able to pull ~20-25% (on average) ahead of the GTX 580 but we have to remember that we're comparing it to a PREVIOUS generation Fermi architecture, not a comparable next generation Kepler part. When you look at it in that context, AMD may still be fighting one hell of an uphill battle in 2012 and need to get product in the channel....NOW.
- I know the above statement sounds like absolute insanity to some around here but it's important to remember that Southern Islands was originally supposed to be introduced on 32nm before the process was cancelled. Think of it as a Tick (New Architecture) to NVIDIA's Tock (Fermi v2) and that would have put Tahiti in a great position. Instead, AMD had to release "Northern Islands" at a low price AFTER NVIDIA's refresh and push their new architecture back to a time when it would be competing in a less dominant position against Kepler.
- Additional performance through "optimizations" for GCN? Quite possibly but I really don't think so since the goal sticks for driver dev are always in movement. Plus, while there may be increases in today's games, will you be playing Crysis 2 6 months from now? How about MW3? Arkham City? No, probably not. You'll be on to the latest and greatest game and while AMD may be upping performance on the games seen in yesterday's reviews, time has proven that it is their support for NEW games that continues to lag behind. So "performance improvements through drivers" be damned (IMO) until they can show proper and immediate support for new releases. Remember, NVIDIA's driver dev. is hardly standing still either so once everything evens out, you won't see any additional separation between the GTX 580 and Tahiti-based cards in upcoming games. And you can quote me on that.
- We can't only think of Tahiti from a purely gaming performance standpoint. AMD has built in enough appealing features like ZeroCore Power that there are more than enough reasons to consider a HD 7970 over any other card currently on the market. From a personal perspective, the HD 7970's power consumption alone has caused me to immediately replace a GTX 580 3GB in my main gaming system. It may be winter up here in Canada but even a few bucks every month saved on my power bill will add up.
- The HD 7970 is priced lower than most GTX 580 3GB cards and slightly above reference GTX 580s. It consistently outperforms both. The fact that people can continue to complain about pricing simply boggles my mind.
