nV今年4季度将推G92, 运算将达近万亿次


顺便说下, G80的峰值US运算能力是340G, 这样算来G92是G80的3倍, ATI今年Q4的日子恐怕更不好过了

In recent analyst conferences that were publicly webcast on NVIDIA's website, Michael Hara (VP of Investor Relations) has claimed that their next-generation chip, also known as G92 in the rumour mill, will deliver close to one teraflop of performance. In a separate answer to an analyst's question, he also noted that they have no intention from diverging from the cycle they have adopted with the G80, which is to have the high-end part ready at the end of the year and release the lower-end derivatives in the spring.

Assuming that NVIDIA manages to hit these aggressive release schedules, it implies that the chip will compete with any potential R6xx refresh at the beginning of its lifetime, but also eventually with R700 as it seems unlikely NVIDIA will refresh again before the second half of 2008, unless they go for an optical shrink from 65nm to 55nm. It also remains to be seen how aggressive ATI will be on the process front this time around.

There also were a number of other highlights during the conference, including a major emphasis on GPGPU (aka 'GPU Computing') and a short mention of Intel's upcoming GPU efforts through their Larrabee project. Micahel Hara seemed far from certain about Intel's exact strategy there, although he did mention that it was possible Intel was more interested in the GPGPU market than the gaming one. This is something we have already said in the past.

And finally, he mentioned that although he does not believe R600 will have any impact on their G80 sales, RV610 and RV630 are much more competitive parts that are likely to gain traction in the marketplace. He argued that he was not convinced 65nm gave AMD a real advantage in terms of costs because of the yield curve, and seemed confident that their own 65nm mainstream parts will be superior. We can't help but wonder how much that matters when you release them 9 months later, though? It will also be interesting to see who's first to 55nm, and how good of a half-node it will be.

:lol: ATI早就有了,藏在抽屉里等N先发,然后A后发先至,给N一个惊喜

就好像R600一样，对N来说确实是个惊喜w00t)

第四季度推的意思是中国什么时候能买到？？？－－－－中端

NVIDIA能力令人佩服...而低估NVIDIA的代價太大了,看看ATI現在寄人籬下就知)_)

方案a：(32 MUL + 128 MAD)*1.5倍单元扩张x1.35GHzx1.5频率提升，这样就能得出875GFLOPS。

方案b：(32 MAD + 128 MAD)*1.5倍单元扩张x1.35GHzx1.5频率提升，这样就能得出972GFLOPS。

方案b开始接近：G*92 = (192 SP+192 SFU)@2.03GHz

相信G92一定令AMD抓狂
我们想想G80-G92同当年NV40-G71十分相似
NV40-G71由130nm-90nm晶圆细少约30%,而G80-G92由90nm-65nm一样约细少30%,由工艺进步方面相当相近.
而68U-79GTX频率由400升至650,而相信G80-G92频率亦能升约1.6倍即88U的612升至979左右,但单单提升频是做不到1 teraflop的
所以相信也会像G71一样由NV40的16条Pixel Shader流水线提升50%到24条的道理,由G80的128 个Streamam Processor提升至196个以今G92达到1 teraflop和令AMD连追的机会也没有...
结论,在11月左右相信会出现一张主频在960-990左右,Streamam Processor达196个的怪物足以令AMD的显卡部门(ATI:p )专心只做中底价显卡...

66/76如果只有68的1/4還有辦法輝煌嗎？XD

:sweatingbullets: 我的意思是G9X上65nm很有可能SP上更大规模，也许不会只有高端1／4

估计不会，8600只有32SP一方面性能固然可以媲美默认频率的79GS，一方面更是工艺的妥协，G9X上65nm的话，有可能继续6600GT／7600GT的辉煌

希望这次的9600不要阉割的这么狠:funk:

NV好久没这么高调过了。这回完全不再掩饰次世代GPU的性能，不知是NV太自信了，还是觉得友商已经无法形成威胁了？
