Ati Radeon Hd3870x2 And Hd3870

摘要

It had been a long time since we got a high-end card from ATI, but this wait ends with the launch of ATI Radeon HD3870X2, a top-end card, which has two GPUs onboard on the same PCB. We just got the ATI Radeon HD3870, a mid-range card along with the recent HD3870X2 for review in our labs. Both cards are based on 55nm technology. but when one compares their capabilities and features then the latter comes powered with almost double capabilities. Compared to the 320 stream processor, 512 MB of RAM and 775 MHz core clock speed of the HD3870, the 3870X2 card has a 640 stream processor, 1 GB of RAM and a core clock speed of 825 MHz. The only glitch with the HD3870X2 is its size; it is 10.5 inch in size, which makes it difficult to be installed on the motherboard, especially if you are planning a Tri-Fire or Quad-Fire configuration using one HD3870X2 and one HD3870 or two HD 3870 cards respectively. The support of HDMI and 5.1 audio channels remains intact as it was with the earlier series cards. Moreover, these cards have got the support for DirectX 10.1, which is even missing from the nVIDIA's latest 9-series.
