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.

    Like many said before, this is truly one of the best readings ive had in a long time. Keep up the good work man!

    Great article, it's excellent to have the back story of the GPU wars.

    It's kind like the planes/tanks on the history channel :)

    5* Anandtech

    Awesome article. Did NOT miss the sea of charts. At all.

    Loved every bit of the tale.

    Easily the best PR a company can get.

    However I was kinda hoping for a little bit more info on the RV670. What did *that* team go through when making the part that is RV770's direct (or no?) predecessor?

    Im acctually concidering buying a GFX to support the company that allowed this interview. Its easily one of the best Ive read.

  • hrishi2das - Wednesday, December 3, 2008 - link

    A great article... very well written and personal...

    Can Anand with his great contacts get us a backstory on the Core 2 arch. That would be another great article.

    As an NVDA shareholder, having a *huge* amount of unrealised loss in the shares, I bought the 4870 a month ago.

    A testament to how good the 4870 is at its price point. It just makes sense.
  • piesquared - Wednesday, December 3, 2008 - link

    All preferences aside, I have to say that was probably, hands down, the best article i've read in a long, long time. Talk about capturing your audience.

    Tremendous insight.

    Well I must say this is a good article because it is something different good work on this one. I do have to ask this has AMD been making GPU's for 8 years really..ok

    I know ATI has for sure but they were not part of AMD then if AMD has been then oops I guess I never owned one of their GPU's before they bought ATI.

    I have to echo the other comments here, wonderful article! One of the best ever on Anandtech.

    And thank you, ATI, for giving the community this kind of access to your hard workers.

    What a great story. Really shows how long it can take to make a significant change towards a process that is right for the end user. All those external factors e.g no GDDR5 at the time and G80s prosperity can really suck out an engineers motivation. Good thing those few engineers stuck to the task.

    The card itself looks so neat and well designed from a bird's eye view. To see how the internals were pateiently designed too is awesome!

    The article showed how the RV770 came to life using just words. Time to introduce my pc to life using this card I say :-)

    I also join the best-article-I've-read-wagon on this one.
