Nvidia worldATI IS ON A ROLL, having taped out its next generation GPU family called Southern Islands. ATI might call it the HD6xxx series, and it could be out before Nvidia gets its GTX4xx line of GPUs fully fleshed out and to market.
南岛已经流片，应该就是下一代HD6XXX系列，估计要比nvidia gtx4XX产品线全部布局完成要早出来。
The news is straightforward enough. Southern Islands (SI) taped out recently, and is now moving through TSMC. Although the schedule is very tight, if all goes really well we could see a demo or two at Computex in just over a month. This puts SI slightly behind where Evergreen was a year ago, but not by much.
Computex大展上应该会有demo演示
Southern Islands is said to be a hybrid between the all new Northern Islands (NI) and the current HD5xxx Evergreen family. Those in the loop say that Northern Islands was meant to be on TSMC 32nm before that process was killed. Due to the ever-slipping nature of TSMC's 28nm high-K metal gate node, the SI hybrid GPU was slapped together to be fabbed on TSMC's current 40nm process.
tsmc取消32nm转向28nm导致北岛延后，只能使用现在的40nm来造一个南岛。
Sources tell SemiAccurate that SI uses some of the NI uncore (unshader?), and wraps that around a mildly updated Evergreen shader. RAM is more of an open question. NI was set to use GDDR5+, but since DRAM makers might not be ready, we may end up with only GDDR5 on SI.
南岛使用混合设计，北岛的uncore和evergreen的shader部分，北岛估计会用GDDR6吧？南岛还是用GDDR5。 |
