AMD Graphics Chip Shortage Hits PC Vendors
CWmike writes "An offshore AMD foundry is having trouble ramping up production of a new 40-nanometer GPU, forcing PC makers to delay shipments of desktop and laptop computers, AMD confirmed today. TSMC is struggling to get up to speed manufacturing AMD's 5800 series, 40-nm GPUs, according to Jim McGregor, an analyst at In-Stat. He added that the foundry is in full production, but so far yields are below expectation. Matt Davis, a spokesman for AMD, confirmed that TSMC is having issues with production of the chips. He added that it's not clear how far behind the foundry is on production expectations. 'The design is sound. It's just a matter of trying to get TSMC to a point where they can yield. They're feeling the manufacturing crunch,' said Davis. 'We're a little bit under yield but we're working back into a manufacturing schedule we want for these parts. TSMC can only kick them out so fast at this point.' He said that PC vendors are being affected but declined to say how many vendors are feeling the pinch or which ones. 'It's the end of the whip,' he added. '[The vendors] are going to have a hard time.'"
A post at Anandtech suggests we'll see price hikes for the 5800-series Radeons until this situation sorts itself out.
This is how nVidia always manages to stay on top: assumption.
I don't know why, but people always assume that nVidia parts are at the least equal, and for the most part better than ATi. Granted they have been in the past, but anyone savvy enough to know about graphics cards should also know how much things can change with every next generation.
I've heard people actually say "It's safe to say that the HD 3800 was pretty much a failure". That had to be one of the dumbest comments I've ever heard from a so-called "true gamer".
Part of the problem in particular with this one seems to be the process. TSMC has decided to blaze their own trail as it were and is going outside the ITRS roadmap. You'll note it says 40nm chips and that's not a typo. They have a 40nm process, whereas pretty much everything else (like Intel and AMD CPUs) are 45nm currently and working on moving to 32nm.
Ok well this roadmap with set nodes isn't for nothing. You don't semiconductor manufacturing in a vacuum, the foundries buy hardware from a number of companies to be able to make their fab work. As such it is useful if everyone has a common goal to work on. If machines for one step are for one process and machines for another are for a different process, you have problems.
Well TSMC has decided to go ahead and make their own process, not something part of the ITRS standard. Ok well that means they are buying some custom equipment or modifying the procedure or the like.
The result? Well it seems to be poor yields. They had a lot of trouble bringing it online, took longer than they planned, and now it doesn't work as well as they'd hoped.
This isn't isn't entirely surprising. How well it works out for them in the long run remains to be seen. They do have the smallest process on the market now as far as I'm aware and both nVidia and ATi are placing orders using it. However I wonder if they'll be shopping elsewhere for future cards, given the problems this is having. They can't change what they've got now (a design for one process doesn't work on another as is) but they can change what they do in the future.
You are also correct, Intel rocks at fabs. They generally beat just about everyone to market with on a new node and they seem to be able to keep yields high enough to meet demand and keep prices at whatever level they like.
