VIA计划在2008年初发布新的处理器架构，取代已经使用了三年的现有架构。
VIA现有的“Esther”(圣经·以斯帖)架构推出于2004年，基于90nm工艺，V4总线频率800MHz，二级缓存128KB。
新架构工程代号“CN”，开发代号“Isaiah”(以赛亚书)，属于64位架构，将采用65nm工艺制造，V4总线频率高达1333MHz，二级缓存也达到1MB，并支持ECC内存和虚拟化技术。
参与新架构测试的厂商透露说，与Esther架构相比，Isaiah架构的处理器在频率上不会有大幅提升，同时功耗会有所增加，但价格会更低，而且目前可以得到的性能已经达到Esther的两倍，浮点单元性能更是翻了两番，有望进一步增加VIA的收入。
Isaiah架构将于今年第四季度进入工程验证测试(EVT)阶段，明年第一季度正式发布。

VIA to launch new processor architecture in 1Q08

Printer friendly Related stories Comments Email to a friend Latest news Related topic: Hot systems Advertisement Monica Chen, Taipei; Joseph Tsai, DIGITIMES [Wednesday 25 July 2007] VIA Technologies is scheduled to launch its new processor core, dubbed Isaiah, in the first quarter of 2008, with the new architecture entering EVT (engineering validation test) stage in the fourth quarter of 2007, according to market sources. The Isaiah core (engineering codename CN) will replace VIA's Esther processor architecture, which was introduced in 2004. Isaiah features a 64-bit architecture and will be manufactured on a 65nm process, as compared to 90nm for Esther. Other features include a V4 Bus speed of 1333MHz, up from 800MHz previously, and support for ECC (error checking and correction) memory and virtualization technology. The L2 Cache will also increase to 1MB from 128KB previously. Although Isaiah's core frequency will not see any obvious increases and power consumption will be higher compared to Esther, its performance so far has been measured to be twice as fast as that delivered by the Esther architecture, and the floating point unit performance is four times greater, according to makers that are testing the new architecture. With the lower cost and better performance, the new processor has a chance to boost VIA's revenues, added the sources

什么时候能和i 竞争主流pc市场就爽了:loveliness:

好消息，VIA　2008终于能拿出图拉丁1G性能水平的CPUw00t)

图拉丁1G性能水平的CPU 早就拿出来了，C7-M 2G

via怎么还不倒闭。:mad:

CPU是VIA主营业务了……VIA也想有所突破……
估计这次能赶上P4 1.8A？VIA也是和Intel拼价格，因为VIA主要做嵌入式，Intel基本不玩这块，NB上VIA份额太小Intel懒得理它，所以VIA没有和Intel正面竞争。VIA就算有本事做出高性能产品也不敢做，只要Intel被惹火了，就能用价格、工艺、授权、产能等一系列武器随便一个把VIA压死。

不知道CPU是采用那种接口???

至少是同胞搞出来的U嘛

比那个骗国家科研经费的虫芯值得骄傲多了啊~~

唉，感觉现在Via的几乎没什么生存空间！Cpu这块他很难有什么大作为，芯片组这块说实在Via已大不如前，kt400之后明显感到Via没落了，而且多了像Nv这样的对手。再就显卡这些不说也罢！

FPU/SIMD pipelined后，吞吐就可以提高一倍了，加上频率的提升、cache的增加，也就达到3x了。
