[Xbitlabs] Ex-AMD Engineer Explains Bulldozer Fiasco: Lack of Fine Tuning - Page 2

you know, i was thinking something like this. FX was strictly to get this new architecture out into the field on a mass scale to see where to focus improvements.
but, if this was the case, wouldnt you think AMD would mention something? i mean, of course they wouldnt say, "hey FX is a beta for the real 'BD'" because then the FX wouldnt sell....but you would think they would start dropping hints instead of backpeddling and twisting statements like "the kid loosing the fight at recess."




idk, like you said, we should all stop assuming for AMD.

Nah, CAD software cares a lot about efficient design. The software tries to compress the design so much that it may cause timing glitches and other design "flaws" that impact stability and eventually performance. This is why a lot of manual debugging is needed.

We're playing around with 1.6 micron process at the university at the moment, and this is what we've encountered. We most definately use different software though

edit:

My bad, CAD software used by AMD makes the die bigger...

idk, like you said, we should all stop assuming for AMD.
The company spent hundreds of millions on R&D and should have done things right the first time. Also, you don't beta test hardware. It works on software because there is sooooooo many different hardware setups that exist and all the development is done through an API that is supposed to play nice with the hardware. Beta testing is to see if there better ways to right code based on community input, hence, why beta's are free.

All hardware in computers has a pretty limited set of standards it has to meet, I mean they all run the same 8 operating systems available, they all communicate with other hardware in pretty much the same way, and on release, there is no free handout of processors to a community to see if they worked all the bugs out.

I do agree with you however that it feels like a crappy beta version of what it is supposed to be, but when the consumer ends up paying for a junk product with no way of recuperating his wasted money, that is just bad business. I suspect that AMD's years of absentee leadership has allowed the development teams to browse redit, FB and other distractions all day instead of actually doing development on the processor.
