The RV870 Story: AMD Showing up to the Fight

Final Words
Unlike a product review, there’s very little I can do to conclude here. There’s no buying recommendation, no performance to summarize. Even as an analytical piece there’s not much for me to conclude based on what I’ve learned at this point. When I wrote The RV770 Story I was convinced that ATI had embraced a new, refocused approach to GPU design, only to learn that they nearly threw out all of the learnings with the RV870.
The Northern Islands GPUs, due out later this year, were surely designed before anyone knew how RV870 would play out. Much less whether or not Fermi/GF100 would be this late.
I’m not sure any of what we’ve seen thus far in the history leading up to the RV770 or RV870 can tell us what we should expect from Northern Islands. While we can’t conclude about ATI’s future products, I do believe I have learned a considerable amount about how AMD’s graphics division works.
Carrell told me that the process of doing a product is not a logical process. There's logic in it, but it's not a logical process. It's an argumentative process. Not in the sense of having conflicts, but rather developing new data when the data isn't all there. When companies like AMD and NVIDIA do a product the engineers don't know all of the answers, and the knowledge they do have isn't binary - it's probability, it's weight, it's guesses. Sometimes they guess right, and sometimes they guess very wrong. The best they can do is to all weigh in with their individual experiences and together come up with the best group of guesses to implement. Over the years it seems that ATI has learned to, as much as possible, have all members of its team bought in to the product they're building.
The graphics team’s dedication and experience in jumping to new process technologies seems to have paid off with this generation. The move from TSMC to Global Foundries will surely challenge them once more. It’s not all about process technology though. The team’s focus on schedule and execution was a much needed addition to the company’s repertoire.
Carrell Killebrew helped turn ATI from a traditional GPU company with a poor track record, to one that could be known for its execution. The past three product generations have been executed extremely well. Regardless of whether you're an AMD, Intel or NVIDIA fan, you must give credit where it's due. The past couple of years have shown us a dramatic turn around from the graphics group at AMD. To go from the shakiness of the R500 and R600 GPUs to solidly executing on the RV670, 770 and 870 year after year is praiseworthy. I almost wonder if AMD’s CPU team could learn from the graphics group's execution. I do hope that along with the ATI acquisition came the open mindedness to learn from one another.

Just like many others, I've been a long time reader and I just couldn't carry on without leaving a comment:This has been an article, just like the RV770 one. It may not reveal many facts but is tremendously insightful and inspiring. Thank you for bringing this deeply hidden information out to the public and to the "fans". Please do everything in your power to continue this trend.
Once again, thank you Anand,

Germans say "lange Rede kurzer Sinn". So many pointless sentences that do not tell anything even remotely interesting.TGressus - Sunday, February 14, 2010 - link

Fantastic article."
First, it massively increased the confidence level of the engineering team. There’s this whole human nature aspect to everything in life, it comes with being human. Lose confidence and execution sucks, but if you are working towards a realistic set of goals then morale and confidence are both high. The side effect is that a passionate engineer will also work to try and beat those goals.
"
Finally, someone accepting and using human nature.
And see it works out...
The fun part is that a requested functionality that is desired but can not make it within the expected timeframe, can still be worked on and can be ready for the next "bulge" in the market. This way you relieve your engineers form stress, you have the time to sort errors and bugs out, you have time to solve unforseen consequences that always happen( people can get sick, a bug in software, machines breaking down) and you have a feature for the market department to market to the consumer for the next iteration of the product. This way you can use the free market to build an in the end perfect device. It is all about balance. If you have to invest to much energy in situation a, you will have less energy for situation b in a certain timeframe. We are bound by laws of nature meaning there is no "perpetuum mobile" in this universe. Nothing comes for free...

Anand, you have taken an article that is really technical in nature, and turned it into something entertaining to read and yet informative for non-engineer types. My hats off to you. This is really the right balance of information and readability. If only all the Scientific Papers I have to read were written like this!dukeariochofchaos - Sunday, February 14, 2010 - link
i wonder if you will give fermi the same drama queen touch?i hope so.

I don't think anyone wants to read nvidia's marketing department tell us how awesome PhysX and CUDA is again tbh.TGressus - Sunday, February 14, 2010 - link
I suspect Fermi will be able to stand on it's technological innovation.RJohnson - Sunday, February 14, 2010 - link
...and it's exorbitant price/die size will exclude mere mortals from owning one.Spoelie - Sunday, February 14, 2010 - link
That depends entirely on the openness of NVIDIA on the subject, historically not one of their strong points.In fact ATi's take on NVIDIA's design process has been more informative than what has come out of NVIDIA itself.
But here's to hoping..
