English to Chinese Tech/Engineering IT (Information Technology) graphics card

Though ATI was first out of the gate with a DirectX 9 card, and the architecture of the Radeon 9700 (the R300 architecture) dominated for quite some time, the company really took its sweet time incorporating more of the DX9 spec（注：指规范）. This year was pretty rough for ATI. The R520 architecture, finally bringing Shader Model 3.0, was set to be released in the second quarter of the year. Unfortunately, R520 fell victim to a small logic bug that was replicated throughout the chip, and it took ATI several revisions to finally find and fix it. This pushed R520 back to the fall, so instead of beating Nvidia's GeForce 7 cards by a month or two, they trailed by 3 or 4 months. When the Radeon X1800 cards finally hit the market, they weren't the slam-dunk ATI was hoping for. The top-end "XT" variant is suitably fast and great competition for Nvidia, but the lower-end cards in the X1000 line don't measure up very well.
