The Test
As we mentioned earlier in this article, since NVIDIA is not shipping cards to reviewers, we do not have a traditional stock unit; and this is compounded by the vast array of speeds vendors can and are offering cards. For the purposes of our testing, we are clocking our Palit GT 220 Sonic Edition to 635MHz core, 1360MHz shader, 900MHz memory, and calling that our stock GDDR3 GT 200. The results should be close to where most of the GDDR3 GT 220s end up.
Meanwhile the 9600GSO we’re using is one of the original G92 based models, which means it has 96SPs, and is clocked at 550Mhz/1375MHz/800MHz, with 384MB of GDDR memory, all on a 192-bit bus. This is not to be confused with the poorly named 9600GSO 512, which is 48 shaders at higher clock speeds and a 128bit bus. It’s this latter 9600GSO that the GT 220 is expected to compete with. Unfortunately we were not able to acquire a 9600GT in time for this review, so this is the next-lowest NVIDIA card that we have on hand to use in our comparison.
Finally, the Radeon 4670 we’re using is a 512MB, 1000MHz memory model. They come as low as 800MHz.

엔비디아의 첫 40나노공정 데스크탑 GPU, GT220은, 라데온 4670보다 많이 떨어지는 성능, 9500GT보다는 조금더 나은성능을 낸다. 추가적으로 도입된 HDMI의 사운드 출력기능과, 저전력인 점은 장점으로 볼수 있고, 현재 시장에서의 위치는 9500GT를 대체할 모델이고, 현재 4670의 가격이 저렴하기 때문에 GT220은 홈쇼핑쪽에서 좀더 강한 모습을 나타낼것으로 보인다.
