R600 is "a mini core" marchitecture

4xRV610 = R600 all in blocks Talking about mini cores and putting more chips together brings us back to the R600. The R600 is nothing more than two times the RV630 or four times the RV610 chip. The only key difference between these chips is the memory controller. The RV630 has 32 Unified Shaders while the RV610 has 16 only. No need to panic as RV630 has 160 stream processors just as Nvidia while the RV610 has 80. However they work completely different than Nvidia's. R700 will be the first real mini core, but even the R600 is made out of blocks. So R600 has four blocks and each of them have 16 Unified Shader units, while RV630 has two blocks with total of 32 Shaders and so on. Compared to CPU dual or quad core marchitecture, graphic is much easier. Graphic calculations are almost always parallel, so a 64 Unified Shader chip can be seen as 64 small processors rendering and calculating together at the same time. We will do another part to explain some more inside information about the R600 stream processor marchitecture, but be prepared to read some complex information.

RV630是2bank不错，但如果是32US，那就比较离谱了 :)

太强了？还是太差？

出来再说！等死人了。

R600好像420mm吧，RV630，一半就是240mm，算上65nm比80nm缩小25%好了，就是180mm,另外位宽128bit，再减个20mm，160mm差不多了:lol:

32*(4D+1D)，这说法没问题呀，他说的是US，不是US array。

PHK是骗子
RV630只有24个US:lol:

Edison

24是指哪一个规格。

这就是这一代VPU的特点,模块化趋势!:loveliness:

我听到的说法是24个5D :unsure:

请思考大人解释一下，5D是什么含义啊？
4D比较好理解，增加的1D是干什么用的啊

谢谢司考， 学习到了

够厉害的了～～～～

如果真的是这样，那RV630和RV610的性能应该很强的，RV610应该就和G84差不多了
