【神棍查理】Computex 2012: AMD to launch Tahiti 2 next week

BDFMK2

AMD is going to be launching Tahiti 2 in the near future, at least according to almost every board maker in Taipei. T2 to T1 in silicon isn’t anything like T2 was to T1 in the movies, but there is a lot of good here.

The short story is that Tahiti 2, aka Tahiti XT 2 in ASIC speak, isn’t actually new silicon, they are just binning better. If you thought that Tahiti/HD7970 was binned really conservatively for yield, you would have been right. Think of it as the polar opposite of Nvidia’s GTX680 footgun binning method.

End result, well over a GHz, but likely to be called HD7970 GHz edition as is all the rage nowadays. People are telling SemiAccurate that final silicon will run from about 1050-1075MHz, so about a 15-20% boost over Tahiti. Since T2 is binned for low leakage, it should run at the same TDP or less than current Tahitis. That means no board changes, no cooler changes, and likely no memory changes either, but all of those things are just fine the way they are now.

As we mentioned earlier, T2 is a real product, unlike GTX680 which was never actually meant to be real according to Nvidia sources. We have good technical reasons to believe Tahiti 2 will have great yields and ship in more than enough quantity, conversely GTX680 never will.

Also, if you are waiting for New Zealand, aka the dual GPU 7990, this ASIC is what AMD was waiting for. While there are other, non-AMD related issues with launching that card, the silicon should no longer be a hold up now.

Last but not least, there will be a new binning of Tahiti Pro, now called Tahiti Pro 2. Sources did not tell us the specs to that part, but it will likely be nothing more than a mild update to better utilize the ASICs that don’t end up being called Tahiti 2. So there you have it, the brand ‘new’ Tahiti 2.S|A

GCN2.0，不知道会往啥方向改进？

看上去没啥大变化

就只是步进不一样吧

查理说的是连步进都一样...

马甲2.0？？还是期待中！

特挑版本，不过查理菊花可以塞下鸵鸟蛋了，爆料可信度。。。。。

AMD的心太黑，逻辑也很简单； 我给你超频，我给你加压，但就是不降价~~~
把产品的价格降到合适，或者让大家惊喜的价格，那是以前那个CEO时代的风格。
换了CEO，就像我以前分析的：商人出生看重利润率，买不买是你的事，卖多少价格是我的事。个人觉得按此趋势，AMD财报上显卡部分的利润率不会低，但是独显市场占有率持续下降。
