Drivers & ISV Relations
As we noted last week with the release of the Catalyst 12.1 preview, AMD has a lot of technical and reputational debt to dig themselves out of when it comes to their Catalyst drivers. AMD dropped the ball this fall a number of times, failing to deliver on appropriate drivers for Rage, Battlefield 3, and The Elder Scrolls V: Skyrim in a timely manner. This isn’t something AMD is shying away from either – they know they screwed up and they’ll admit as much – but the question remains of how they intend to improve from there. Now that they once again have the leading single-GPU video card they need to have the leading drivers to run it.
Part of this redemption will come from the addition of new features, if only to reach parity with NVIDIA. Catalyst 12.1 introduced custom application profiles, while as we discussed with Eyefinity, Catalyst 12.2 will add to AMD’s suite of Eyefinity features with custom resolutions and the ability to relocate the Windows task bar. Furthermore AMD has features in the development pipeline for their Catalyst drivers for introduction later this year, but at this point it’s too early to talk about them.
But new features alone can’t fix every single thing that has ailed AMD in the past year, so the question remains: how does AMD intend to fix their poor delivery of optimized drivers for new games? It’s a question AMD cannot (or will not) completely answer in detail, but it’s a question for which there’s at least part of an answer.
The fundamental answer is more. More developers, more quality assurance, and above all more money. By all accounts NVIDIA sinks a lot of money into driver development and ISV and it usually shows. AMD is going to spend more resources on driver development at home and this is going to help a great deal, but at the same time it would seem that they’ve finally come to realize that great ISV relationships require that AMD be more proactive than how they’ve been in the past.
ISV relations covers a large umbrella of activities. Not only does this mean providing support to developers who request it, but it means providing cross-promotion marketing, encouraging developers to make use of your features (if only to help spur the creation of the killer app), and actively seeking out important development houses so that AMD’s interests and concerns are represented and represented early. It’s been said that the most important thing NVIDIA ever did with ISV relations was to send out their own engineers to development houses on their own dime to provide free support – essentially investing at least a small amount of money into a major game. The payoff of this was that NVIDIA was literally there to represent their interests, and conversely they had a chance to evaluate the game early and get to work on optimizations and SLI support well before it shipped. Snark about TWIMTBP aside, that’s where NVIDIA has raised the bar with ISV relations. That’s what AMD needs to follow.
To that extent AMD has reorganized the budget process for their ISV relations department. Neal Robison, the director of ISV relations, now directly controls a much larger ISV relations budget, whereas previously the ISV relations budget was apparently controlled by several parties. Having more funding for ISV relations won’t solve AMD’s issues on its own – It’s all about how that money is spent – but clearly AMD is on the right path by being able to afford to be more proactive about their ISV relationships.
Whether these changes will pay off as AMD is expecting them to remains to be seen, but from our discussions it’s apparent that AMD is trying harder than ever before. A great product requires good hardware and good software; AMD has the former in Tahiti, now it’s time to see if they can deliver on the latter.
Closing out the subject of drivers, AMD is also using the Southern Islands launch to outline their plans for Windows 8. AMD is promising that they will deliver drivers for Windows 8 on the same schedule as they have for Windows 7 and Windows Vista – new drivers will be available for the Windows 8 Beta, RC, and RTM releases. Furthermore as Microsoft has continually iterated on the WDDM driver stack since Vista, AMD will continue to be able to offer a single unified driver that covers all of the WDDM OSes (Vista, 7, and 8).

I think this card is a kinda fail. Well, maybe it is a driver issue and they'll up the performance 20-25% in the future but it is still not fast enough for such huge jump - 2 nodes down!!!It smell like a graphics Bulldozer for AMD. Good ideas on paper but in practice something doesn't work quite right. Raw performance is all that counts (of course raw performance/$).
If NVIDIA does better than usual this time. AMD might be in trouble. Well, will wait and see.
Hopefully they'll be able to release improved CPUs and GPUs soon because this generation does not seem to be very impressive.
I've expected at least triple performance over the previous generation. Maybe the drivers are not that well optimized yet. After all it is a huge architecture change.
I don't really care that much about that GPU generation but I'm worried that they won't be able to put something impressively new in the next generation of consoles. I really hope that we are not stuck with obsolete CPU/GPU combination for the next 7-8 years again.
Anyway: massively parallel computing sounds tasty!

You dont seem to understand that all them extra transistors are mostly there for computing. Thats mostly what this was designed for. Not specifically for gaming performance. Computing is where this card will offer massive increases over the previous AMD generation.Look at Nvidia's Fermi, that had way more transistors than the previous generation but wasn't that much faster than AMD's cards at the time. Because again all the extra transistors were mainly for computing.
And come on LOL, expecting over triple the performance?? That has never happened once with any GPU release.

The 9700pro was up to 4x faster then the 4600 in certian situations. So yes it has happened.tzhu07 - Thursday, December 22, 2011 - link
LOL, triple the performance?Do you also have a standard of dating only Victoria's Secret models?

I have a 3870 which I got in early 2007. It still does well for the main games I play: Dawn of War 2 and Starcraft 2 (25 fps has been fine for me here with settings mostly maxed). I have eyeing a new card. I like the power usage and thermals here. I am not spending $500+ though. I am thinking they are using that price to compensate for the mediocre yields they getting on 28nm, but either way the numbers look justified. I will be look for the best card between $150-$250, maybe $300. I am counting on this cards price coming down, but I doubt it will hit under $400-350 next year.No matter what this looks like a successful soft launch of a video card. For me, anything smokes what I have in performance but not so much on power usage. I'd really not mind the extra noise as the heat is better than my 3870.
I'm in the single card strategy camp.
Monitor is a single 42" 1920x1200 60 Hz.
Intel Core i5 760 at stock clocks. My first Intel since the P3 days.
Great article.

Can someone explain the different heights in the die-size comparison picture? Does that reflect processing-changes? I'm lost. :D Otherwise, good review. I don't see the HD7970 in Bench, am I blind or is it just missing.Ryan Smith - Thursday, December 22, 2011 - link
The Y axis is the die size. The higher a GPU the bigger it is (relative to the other GPUs from that company).Death666Angel - Friday, December 23, 2011 - link
Thanks! I thought the actual sizes were the sizes and the y-axis meant something else. Makes sense though how you did it! :-)MonkeyPaw - Thursday, December 22, 2011 - link
As a former owner of the 3870, mine had the short-lived GDDR4. That old card has a place in my nerd heart, as it played Bioshock wonderfully.Peichen - Thursday, December 22, 2011 - link
The improvement is simply not as impressive as I was led to believed. Rumor has it that a single 7970 would have the power of a 6990. In fact, if you crunch the numbers, it would be at least 50% faster than 6970 which should put it close to 6990. (63.25% increase in transistors, 40.37% in TFLOP and 50% increase in memory bandwidth.)What we got is a Fermi 1st gen with the price to match. Remember, this is not a half-node improvement in manufacturing process, it is a full-node and we waited two years for this.
In any case, I am just ranting because I am waiting for something to replace my current card before GTA 5 came out. Nvidia's GK104 in Q1 2012 should be interesting. Rumored to be slightly faster than GTX 580 (slower than 7970) but much cheaper. We'll see.
