GTS 250测试

Sirlion

4850 1G的功耗比4850 512要低……为什么？？

troopersky

这个新出的250如果显存只有512m的话和9800gtx+几乎就是一样的成绩。换上了1g的显存就高了一些。总的来说性能和1g版的4850不分伯仲。
还有双卡的SLI或者交火比单卡双芯片的效率高很多。

非公版啊，电压可能有所不同

同样是512MB显存，GTS250确实是比GTX+要快一些，幅度很小

Asuka

这。。。搭配新驱动。。。。
核心也没啥区别啊。。。快在哪啊。。。。

DID不同

NV的新驱动可能识别不同的DID然后采取不同的优化路径

寒......FAY CRY2和Fallout3  GTS两百五都战翻了98GX2了....囧囧囧

都是512MB VRAM，SLI对显存要求更高，很正常

ASUKA,有没有最新的1G GTS250 三星显存的BIOS？

黑A本质不改，带倾向性选择测试结果。貌似GTS250这种档次的卡选1920x1200更合理些

goldman948

9800gtx+还要两个6pin gts250只要1个,估计9800gtx+要大跳水了清仓了

苯苯小哥

1G显存啊 高98+一倍啦 为啥98+等老产品不用新驱动182.06？

确定XFX那个是公版？

koppie

但是同样的核心, 为什么要采取不同的路径呢

请你自己看清楚帧数

我选2560分辨率的都是因为1920下极其流畅的项目

MAGICWIN

软升级很成功啊，是不是9800GTX不刷成二五零就得不到新驱动的支持了？

可能是一些市场策略方面的考虑

不过这个结论只是基于我个人的猜测

If we focus on what is likely to be the target resolution of 1680x1050, the Radeon HD 4850 ties its direct competition, the GTS 250 512MB, the Radeon HD 4850 leads more often than it trails or loses. The 1GB GTS 250 does edge out the 4850 in one more benchmark, but it does cost $20 more and we haven't tested the 1GB 4850 which might make the difference.

We've recommended the 4850 over the 9800 GTX+ in the past, and we'll continue to do so now that it's called the GTS 250. But the extra memory does help out, especially if the card is to be used for 1920x1200 on a budget (or maybe with an HDTV).

Power consumption is an advantage the GTS 250 1GB holds. The new board design is only required on the 1GB model, and board vendors may opt for the new design on their 512MB parts, but they may also stick with their current 9800 GTX+ designs. We expect that at first the 512MB GTS 250 will more closely resemble the 9800 GTX+. This does mean we are left with the oddity of the 1GB part drawing less power than the 512MB part for now. Once we get a 512MB version with the new board revision we'll have to take another look at power draw.

The GTS 250 1GB is a better option than it's 512MB brother, and it's also a better option than the 4850 based on our tests. It isn't a game changing difference, but its an edge nonetheless. Is the added performance worth the extra $20? That has to come down to the individual gamer.

UPDATE: We are hearing rumblings of a price drop for the Radeon HD 4870 512MB to $150, and if this happens, there will be no contest between the two. AMD will handily lead at the $150 price if they can get their partners to adjust the price down this much. But doing this would also eat into the market for the 4850, as the jump in value for the extra money would be way more than worth it. Spending $150 over $130 (for either the 4850 or GTS 250) and getting the performance jump from the 4870 is just a no brainer. With the extra RAM, not even the 1GB GTS 250 can compete with the 4870, so IF we see the price adjustment THEN the GTS 250 1GB will be a non-starter. Without this price adjustment, our conclusion stands as is.

对此显卡的单solt版本很有兴趣{victory:]
