某淘宝页面上的显卡信息。。。


5770 76.8GB/sec  的带宽都很严重的瓶颈了.....460 192bit没比5770多多少啊

西把拉古

胜在sp单元啊，260的216都和5770持平了，336还多了120呢。

NV60

新一代8800GS啊~~~~~~~~~~~~~

显存频率低可以超，容量少小就没救了，NV一定不会让媒体开8xAA测。。。

5770 5870 提升显存频率 未见性能有多少提升  192bit DDR5 显存带宽完全没什么问题

solidusmic

要知道几个月前的中端神器5770 不过128bit阿
还自我陶醉与128bit gddr5=256bit ddr3

oscar1987

要买也买256版的

苯苯小哥

要不还出个256bit的 用这个规格来限制档次

stuart123

192bit没什么不好 768m才是大麻烦

大哥频率不同啊，3600对4800啊。如果不超频，5770的带宽和460 192差别太小了。

然后呢，你的后半句 ，正好我手头用8800GTX 384bit GDDR3，460是不是要自我陶醉在192bit gddr5=384bit gddr3一下？

solidusmic

是的.所以这一切都是浮云
也不能光看性能

关键还是价格


性价比,.屁民们最关心的问题

否则早就去买5870/480了

性价比

现在新出的卡，让人越发的看不懂了！！！

紫夜星辰

要上就上1G的吧
