R300 效能 (轉載)
根據這篇報導，R300 在目前驅動程式下，約快 Ti 4600 15~20%。
原文： 3DGPU.com
Got an email from a Hong Kong reader with some details that a magazine over there posted some R300 performance numbers. This is what he wrote in the email:
引用:
I found that a Hong Kong Magazine PC Market did talk about the performance of the ATI's new generation card, R300. They said that the performance of the R300 will be about 20% better then Geforce 4 Ti4600, and they did run 3DMark 2001se, however due to under the NDA, they can't tell us the exact number. They test the R300 in the VIA KT400 demo at Taiwan Computex.
If you want, I can scan you a copy of the article, but it is in Chinese. I just think that if ATI R300 really have 700mhz DDR ram and 256bit memory bus, 20% performance increase over Ti4600 is really not that great.
I asked him to scan a copy of the article if he could. I agree, that just 20% over a Ti4600 isn't overwhelming, but the drivers are definitely not final, and I'm sure with more tweaking and work on it, that 20% can be much higher.

Update: Cheung was able to scan the magazine, which you can check out the image here: http://www.3dgpu.com/misc_images/pcmarket-r300.jpg.
He translates a bit from the article for us:
引用:
We saw a R300 demo in another Computex VIP Rom (sorry, it looks like not from VIA). We cannot tell you the 3DMark 2001 score due to NDA, but we can tell you it "is faster than Gefore4 Ti4600 about 15-20%.
It also tell us that the announce date of RV250 will be 20th of July, and RV250 will have one more RAMDAC compare to RV200, but they don't have futher information. They saw 2 ATI RV250 card, one is unknown brand, with Hynix 3.3ns memory, the other one is from Gigabyte.
