很显然，“New Zealand”(新西兰)将是新一代旗舰级单卡双芯型号(新西兰本身就是南岛、北岛两大岛屿组成的)，取代Antilles Radeon HD 6990，我们可以暂时推测它会叫做Radeon HD 7990。
“Tahiti”(塔希提)是高端核心，将会取代Cayman Radeon HD 6970/6950。它有两个版本Tahiti XT、Tahiti PRO，按惯例会分别命名为Radeon HD 7970/7950。
“Thames”(泰晤士)是主流级别核心，并且分为Thames XT/GL、Thames RPO、Thames LE三个版本，看起来会分别取代Barts Radeon HD 6870/6850/6790，型号上顺应叫作Radeon HD 7870/7850/7790。Thames XT/GL同时还代表着FirePro专业卡版本。
“Lomlock”(龙目岛)则是低端核心，将会衍生出一体机版本Lomlock AIO、专业版本Lomlock GL和两个消费级版本Lomlock XT、Lomlock PRO。最后两个猜测会叫Radeon HD 7670/7650，取代Turks Radeon HD 6670/6570。
大家可能注意到了，入门级核心Caicos Radeon HD 6450怎么后继无人了？这也是必然的了，Fusion APU的诞生将使这种入门级独显变得完全没有必要，Lomlcok这种低端核心更大的作用估计也就是配合APU组成双显卡系统。
另外还有一种比较“耸人听闻”的说法，声称New Zealand、Tahiti、Thames都会使用AMD日前提出的全新图形与计算架构“AMD Graphics Core Next”，只有低端的Lomlock继续使用Radeon HD 6900系列引入的VLIW4架构。难道AMD真能跑这么快，今年第四季度就带来新架构？
From SemiAccurate:
What is going on with Southern Islands, the next generation ATI (NYSE:AMD) graphics card? When is it coming out? What is it?
The last one, what is it, is easy. AMD told us all about it at Fusion 11, or at least the shader architecture, so the only open questions are how many of them, and when will we see it? Both are dictated by TSMC’s 28nm process, or are they?
OffiCIal word is that TSMC is coming out with 28nm products in Q3 of this year, that would be some time from next week to the end of September. Given the foundry’s track record on 40nm, we are fairly skeptical about this. Moles say that 28nm non-HKMG is doing just peachy, but the 28nm HKMG process is having the proverbial issues. Lets hope these are the normal bring up/teething issues and things are on time for the sake of the entire industry.
Back to Southern Islands (SI). At Computex, AMD was telling all the vendors Q1, which means TSMC would start ramping in Q4, and have volume in Q1, but in reality, don’t count on things going well. The problem is that other sources are now saying that things are going really really well, and signs are looking like it is September-ish, not February-ish.
If you look at when SI taped out, chips could possibly be on the market in mid-Q3. That date assumes that TSMC is willing, able, and has wafer starts to spare. SemiAccurate is pretty sure that the first is true, the third looks somewhat questionable, and the second is the open question. Considering that there are Apple chips coming off the line now, quite possibly 28nm Apple chips, then that means that TSMC is able, but puts wafer availability in serious doubt.
One other slim but intriguing possibility surrounds SI, is it on 40nm? Northern Islands was originally set for the canceled 32nm process, and was then backported to 40nm, so things like this can and do happen. Could there be some 40nm SIs that come early, then a quick 28nm refresh when our Taiwanese buddies have their wafers ready? Could the line be split between 28 and 40?
Overall, we doubt there will be any 40nm SIs, but technically speaking, it could happen. Southern Islands is much more likely 28nm, and quite possibly coming in very short order. Q3 should be easy if 28nm HKMG works, is on time, and AMD can get the capaCIty it needs. Some other data points show that AMD is looking hard at late August as the earliest possible launch date, but September is more traditional, whatever the process geometry.S|A
