Lol, AMD consolation thread. There's a few things TC overlooked:
1. AMD/ATI cards mostly perform better at higher resolutions because their cards always have more memory. GTX 680 has 2GB RAM while the HD 7970 has 3GB. Two years ago, the HD 6870 had 2GB of RAM while the GTX 580 had only 1536MB. This has been the case since the HD 5970. The difference becomes even more apparent with duel gpu or SLI/Crossfire setups. So yeah, performance at higher resolutions are a no brainer.
2. The HD 7970 came out almost a year ago, about 10 months to be exact. Back, then, it lost to the GTX 680 in most areas, even Crysis 2 and non-Unreal engine games. The 680's lead over the 7970 in terms of framerate was small, but if this little edge is all AMD/ATI can come up with after 10 months, I'm not sure if it's something worth getting excited about. 10 months is quite a long time. For all you know, Nvidia already has a trump card, but is holding back on releasing it just to see what AMD can come up with.
3. And the whole assumption about transistors is quite pointless nowdays. Yes, more transistors GENERALLY give an indication of how powerful a card is. A card with 4 billion transistors will most likely be more powerful than a card with only 800 million transistors. However, the GTX 680 had 3.54 billion transistors compared to the 7970's 4.31 billion, and yet, 10 months ago, the GTX 680 won the 7970 in many areas. This isn't the NES era, where the strength in hardware boiled down to bits. The 7970 is 512-bit while the 680 is only 384-bit. All these figures about transistors and bits are abstract and superficial in today's day and age. Performance nowadays is all about ARCHITECTURE. And expanding upwards isn't necessarily better than expending say....sideways.
4. The article posted is about AMD's Catalyst, which is a driver. It's software, not hardware. What AMD did was optimize their code for the cards. So what we can say for sure is that the 7970 isn't necessarily weaker than the 680, but it's vice versa. Maybe Nvidia drivers for the 600 series cards are unoptimized as well. And maybe Nvidia just can't be bothered because they may be focusing their resources on the next generation of cards.
Bottom line - Don't compare two cards which came out 10 months ago based on a driver for one card which came out 10 months later. There's no such thing as a perfect driver. The more work they put into driver optimization, the better it will be. That's definite. The bigger question that Nvidia and AMD would ponder is - would it be better to focus on their current cards, or future cards?
