Kepler 28nm taped out

Edison

Works well

The successor to Nvidia’s Fermi architecture, a certain GPU that goes by the name Kepler has already been taped out.

We have multiple sources to confirm that the new 28nm chip is alive and that it looks quite well. Nvidia didn't have any major obstacles with the first tape out, but naturally there is still a lot of work to seal the leakage, and make the chip generally better. This is nothing unusual for a new chip, and getting from 40nm to 28nm is definitely not a walk in a park.

Kepler naturally gets a lot of changes to Nvidia's GPU and you can imagine that with the same maximal TDP, you can squeeze significantly more transistor and get much more power.

The optimistic projection is to see Kepler in retail in Q4 2011 but some sources suggest that this won't actually happen this year, as TSMC needs a bit more time to make the 28nm more mature.

Current generation GPUs are already hitting the performance wall at 40nm and the industry has a lot riding on the 28nm process, but fear not. For the moment, both AMD and Nvidia seem to be on track and we might see the first 28nm chips by the end of the year, but mass availability comes a bit later.

28nm 快点上市吧，40 nm 的剩菜实在是不给力

{:5_194:} AMD的新架构不知道是不是kepler的对手。

Q4 的事情，快不了。

某厂第一块。

按进度来看，估计下周或者下下周应该就能开始有R7K的消息了

不知道nv把kepler的规模设定在多少W

fermi显然是有点大了

hd7000还是4D架构

1024个cuda核心是必须的{lol:]

kepler 是架构代号，自然有上中下多个具体的型号。

自然是指旗舰型号啦
我觉得fermi旗舰规模偏大，性能/功耗得甜点可以说在300w~350w了。造成了在风冷下勉强才能达到最佳点。
而按摩店的开曼则有些偏小。性能/功耗的甜点基本上落在150w~200w左右。即便再超频，功耗大幅上涨的同时，性能却上涨的很少了。

搞。。。。。。。。

但愿开普勒是1536SP 256TMU{hug:]

esgehtmirgut

开普勒旗舰显卡什么时候能出
40nm这代太搓了

骨刺

1536 1536{lol:]

esgehtmirgut

512SP能到1024SP已经是不可思议了，1536的话，硬件商一步到位就不能骗钱了

平均提升60%左右了不得了 。
