The RV870 Story: AMD Showing up to the Fightby Anand Lal Shimpi on February 14, 2010 12:00 AM EST
- Posted in
My love/hate relationship with AMD PR continued last year. But lately, it’s been far less hate. Let’s rewind back to the Summer of 2009. I’d been waiting for AMD to call for weeks.
We all knew that the RV870 was going to launch sometime before the end of the year, and we’re normally briefed on new GPUs around a month or so before we get hardware. The rumors said that the launch had been pushed back, but just like clockwork I got a call in June or July of last year. It was my old friend, Chris Hook of AMD PR.
This time he wanted me to come to a press event on a carrier off the coast of California. Sigh.
It’s not that I have anything against carriers. It’s just that all I cared about at that time was the long awaited successor to the RV770. The RV770 was the GPU that unequivocally restored my faith in ATI graphics, an impact shared by others last June. But that’s not how the game is played I’m afraid. AMD promises its management and its partners that they can fill a room (or carrier) up with important press. We get promised access to engineers, useful information and free drinks.
The USS Hornet. GPUs are in there.
I’m not easily swayed by free drinks, but Chris Hook knows me well enough by now to know what I’d appreciate even more.
The Dinner - September 2009
I had to leave dinner earlier than I wanted to. ASUS’ Chairman Jonney Shih was in town and only had one opportunity to meet me before I left Oakland. Whenever either of us happens to be in the same town, we always make our best effort to meet - and I wasn’t going to let him down. In the same vein that Steve Jobs is successful because he is a product guy at heart, running a company best known for its products. Jonney Shih is an engineer at heart, and he runs a company who has always been known for their excellence in engineering. This wasn’t just another meeting with an executive, this was a meeting with someone who has a passion for the same things I do. His focus isn’t on making money, it’s on engineering. It’s a rare treat.
My ride was waiting outside. I closed the lid on my laptop, making sure to save the 13 pages of notes I just took while at dinner. And I shook this man’s hand:
Before I left he asked me to do one thing. He said “Try not to make the story about me. There are tons of hardworking engineers that really made this chip happen”. Like Jonney, Carrell Killebrew has his own combination of traits that make him completely unique in this industry. All of the greats are like that. They’ve all got their own history that brought them to the companies that they work for today, and they have their own sets of personality traits that when combined make them so unique. For Carrell Killebrew it's a mixture of intelligence, pragmatism, passion and humility that's very rare to see. He's also a genuinely good guy. One of his tenets is that you should always expect the best from others. If you expect any less than the best, that’s all you’ll ever get from them. It’s a positive take on people, one that surprisingly enough only burned Carrell once. Perhaps he’s more fortunate than most.
Mr. Killebrew didn’t make the RV870, but he was beyond instrumental in making sure it was a success. What follows is a small portion of the story of the RV870, the GPU behind the Radeon HD 5800 series. I call it a small portion of the story because despite this article using more than eight thousand words to tell it, the actual story took place over years and in the minds and work of hundreds of engineers. This GPU, like all others (even Fermi) is the lifework of some of the best engineers in the industry. They are the heroes of our industry, and I hope I can do their story justice.
As is usually the case with these GPU backstories, to understand why things unfolded the way they did we have to look back a few years. Introducing a brand new GPU can take 2 - 4 years from start to finish. Thus to understand the origins of the Radeon HD 5800 series (RV870) we have to look back to 2005.
Sidebar on Naming
AMD PR really doesn’t like it when I use the name RV870. With this last generation of GPUs, AMD wanted to move away from its traditional naming. According to AMD, there is no GPU called the RV870, despite the fact that Carrell Killebrew, Eric Demers and numerous others referred to it as such over the past couple of years. As with most drastic changes, it usually takes a while for these things to sink in. I’ve also heard reference to an RV870 jar - think of it as a swear jar but for each time someone calls Cypress an RV870.
Why the change? Well, giving each member of a GPU family a name helps confuse the competition. It’s easy to know that RV870 is the successor to the RV770. It’s harder to tell exactly what a Cypress is.
AMD PR would rather me refer to RV870 and the subject of today’s story as Cypress. The chart below shows AMD’s full listing of codenames for the 40nm DX11 GPU lineup:
|ATI Radeon HD 5900 Series||Hemlock|
|ATI Radeon HD 5800 Series||Cypress|
|ATI Radeon HD 5700 Series||Juniper|
|ATI Radeon HD 5600/5500 Series||Redwood|
|ATI Radeon HD 5400 Series||Cedar|
Given that we still haven’t purged the RVxxx naming from our vocabulary, I’m going to stick with RV870 for this story. But for those of you who have embraced the new nomenclature - RV870 = Cypress and at points I will use the two names interchangeably. The entire chip stack is called Evergreen. The replacement stack is called the Northern Islands.

simtex - Sunday, February 21, 2010 - linkExcellent article ;) Insider info is always interesting, makes me a little more happy about my -50% AMD stocks, hopefully they will one go up again.
NKnight - Wednesday, February 17, 2010 - linkGreat read.
- Friday, February 19, 2010 - link
you should write a (few)book(s); of course in multi eReader formats
- Saturday, February 20, 2010 - linkNvidia blames sales shortfall on TSMC
one dot you didnt connect in the article was AMD's foundry experience, which gives AMD a big advantage over NVIDIA; must have been an oversight?
truk007 - Tuesday, February 16, 2010 - linkThese articles are why I keep coming here. The other sites could learn a lesson here.
dstigue1 - Tuesday, February 16, 2010 - linkI think the title says it all. But to add I also like the technical level. You can understand it with some cursory knowledge in graphics technology. Wonderfully written.
sotoa - Tuesday, February 16, 2010 - linkExcellent work and very insightful indeed!
juzz86 - Tuesday, February 16, 2010 - linkAn amazing read Anand, I can wholeheartedly understand why you'd enjoy your dinners so much. One reader said that these were among the best articles on the site, and I have to agree. Inside looks into developments in the industry like this one are the real hidden gems of reviewing and analysis today. You should be very proud. Thanks again. Justin.
talon262 - Tuesday, February 16, 2010 - linkHell of an article...congrats to Anand for putting it out there and to the team at ATI for executing on some hard-learned lessons. Since I have a 4850 X2, I'm most likely going to sit Evergreen out (the only current ATI card that specs higher than my 4850 X2 (other than the 4970 X2) is Hemlock/5970 and Cypress/5870 would be a lateral move, more or less); while I run Win7, DX11 compatibilty is not a huge priority for me right this moment, but I will use the mid-range Evergreen parts for any systems I'll build/refurb over the next few months.
Northern Islands, that has got me salivating...

Peroxyde - Monday, February 15, 2010 - linkThanks for the great article. Do you have any info regarding ATI's commitment to the Linux platform? I used to see in Linux forums about graphics driver issues that ATI is the brand to avoid. Is it still the case?
