The RV770 Story: Documenting ATI's Road to Success

Dave Baumann Saves the Radeon HD 4850
ATI had this habit of finding good reviewers and bringing them on staff. Our first Graphics Editor, Matthew Witheiler, went to work for ATI after graduating from Duke. He was with AnandTech for a good three years before ATI snagged him, he ended up being ATI’s youngest Product Manager (congrats on the engagement Matthew). One other prominent reviewer ATI grabbed ahold of was Dave Baumann of Beyond3D fame and brought him on to do technical marketing.
One of Baumann’s strongpoints was the ability to analyze the competitive landscape given that’s what he did for Beyond3D before ATI. One of Dave’s first major tasks at ATI was to compare R600 to G80 internally, which wasn’t exactly the best job in November of 2006. Obviously, G80 had a significant impact on RV770. While the architecture was set in stone, clock speeds, board layout and memory sizes were all variable until early 2008.
Initially, RV770 was targeted at 1.5x the performance of R600, which looking back would not have been enough. During the next 1.5 years that 1.5x turned into 2x R600 and finally settled at 2.5x the speed of R600, at a price in the $200 - $300 range.
Dave became a product manager on RV770 by February 2008, which was a big deal given that he hadn’t been with ATI that long and this was a very important product. RV670 saw ATI return to competition in the year prior, but RV770 needed to put ATI back on top.
When Dave took the 770 under his wing a lot of the product had already been mapped out, the chip was back from the fabs and at this point ATI’s engineering team wasn’t ready or eager to make any changes. The RV770 XT sat well with Mr. Baumann (the XT was the internal name of the Radeon HD 4870), in his words “the specifications were perfect”. There was a late change to the 4870 that gave it its second PCIe power connector, but that’s it. Arguably the more important version, the RV770 Pro that would become the Radeon HD 4850, concerned him - it was a bit under spec’d.
Here’s a quick put-yourself-in-ATI’s-shoes test. Your engineering team has spent the past three years on a product that may fail miserably because it’s a radical departure from how you’ve designed GPUs in the past. Your last major GPU architecture launch failed miserably (R600), and the last refresh (RV670) did ok but still didn’t really snag real mindshare from NVIDIA. You’ve just finished this radical new design, and this young new PM with an accent comes in three months before you’re supposed to enter production and tells you that you need to make changes. It was a ballsy move by Baumann, but he wasn’t interested in saving face, he was trying to help his team win. The engineers could’ve just as easily cast him aside, but they listened and they worked, oh did they work. The final stretch is rarely the quickest or the easiest, and this is very true about RV770.
The Radeon HD 4850 was originally a 256MB card with a 500MHz core clock and 900MHz memory clock. Dave insisted that the card needed 512MB of GDDR3 and 625MHz core / 993MHz memory clock, it’s not just that he insisted, but that he convinced the engineers to make such a late change. Dave took the engineers through his reasoning of why and where ATI needed to be in the competitive landscape, by the end of the discussion he didn’t need to persuade them, the board and ASIC teams were championing the changes.
Had it not been for these modifications, the 4850 would not have put as much pressure on NVIDIA’s GeForce 9800 GTX and its pricing wouldn’t have needed to fall so quickly.
Thanks Dave.

absolutely brilliant. i've always read anandtech instead of tomshardware because of objective reviews. i was reading an intel review, and people were questioning the objectivity of anandtech. while some might could look at this as praising ATI/AMD, i would definitely say this was a very objective view of what happened. seriously, one of the BEST articles i've read since the 4850/4870 review.kevyeoh - Thursday, December 4, 2008 - link
I've been reading anandtech for years and there wasn't any article that makes me wanna read every single word of it. Usually i will read the forewords and then skip on to the Conclusion. But for this article, i really read every single words! period! Anandtech rocks!nitemareglitch - Thursday, December 4, 2008 - link
I was actually getting a little bored with the articles around here, until I read this one. Great job, I loved reading this story!!lchyi - Thursday, December 4, 2008 - link
This is by far the best (and most insightful) article I have read here to date Anand. It sounds like you put in a ton of thought to it and I have never flown through 7,500 words as quick as that read. Congrats to the ATI guys for their successful gamble on the RV770. The last three years must have been an extremely interesting experience for them and their engineers.joshjnm - Thursday, December 4, 2008 - link
Great article I will bandwagon with the rest of you and agree this is one of the best articles I've read in a while.josh6079 - Thursday, December 4, 2008 - link
I thoroughly enjoyed the article. Last time I was really involved with graphics cards was when the X1900's were in full swing and G80 was on everyone's mind. The history told in the article helped bring me up to pace as to what has transpired since I stopped gaming as much. I can remember how the Video card section used to be here on the forums with the trolls and constant flames. Two camps of people cheered on for one or the other competitors instead of realizing that they should be cheering for competition itself.Great job ATI, Nvidia - what's next?

Very good article, most of these interesting background stories are written in books, but a lot of years latter.Something, that is not mentioned, is that it seems that AMD didn't affect ATI in any way (technically speaking). Many thought that the R600 failure had something to do with AMD.

Awesome article.I am definately a performance/mainstream kinda guy in this market. Definately love the competition. I started my first build with a Geforce 4200Ti, moved up to the infamous 9700Pro, followed by X1900, and now 4850HD...
It is good to see that the ATI/AMD didn't damage ATI as a whole. Rock on guys! Love those cheap kick ass Crossfire cards! Go 4850HD x2.

as a long time reader of anand I never felt the need to register an account; however, after reading your article I felt compelled to create an account just to commend you on an excellent article.we need more articles that give us insight into business decisions like this. job well done mate!

Anand,I've been a long time reader of AnandTech but I especially liked this article. It was interesting to get a peek behind the curtain to see what challenges companies face when making these tough decisions. Hopefully more companies take a chance and share more of their stories with this site. Keep up the good work.
Regards,
John Wright
