Matrox heeft vandaag de G450 aangekondigd, een G400 geproduceerd op 0.18 micron en met een geïntegreerde flat panel transmitter, TV-out encoder en een tweede RAMDAC. Het geheugen is van SDR naar DDR gegaan maar ze hebben de geheugen interface van 128 bit naar 64 bit gebracht wat een winst opleverd van 0,0 Gb/s aan bandbreedte :
Montreal, Canada, April 25, 2000—Matrox Graphics Inc. today announced the new 0.18-micron Matrox G450 2D, 3D and DVD graphics chip. The Matrox G450 AGP 2X/4X chip leverages a die shrink of the 0.25-micron Matrox G400 chip technology to integrate a digital flat panel transmitter, TV-out encoder, second RAMDAC and 64-bit DDR memory interface. By integrating these components directly on the chip, the company has re-architectured its award-winning Matrox G400 graphics technology into a full-featured accelerator that is set to standardize DualHead Display across more markets than ever before. Matrox's exclusive DualHead Display is a state-of-the-market technology that provides immediate and valuable benefits by allowing users to double their display real estate by pairing two display screens (RGB monitor, flat panel or TV) as many as eight different ways.
Display versatility is further enhanced by the Matrox G450's 165 MHz Transmission-Minimized Differential Signaling (TMDS) transmitter, which outputs to a DVI-based digital flat panel at resolutions as high as 1600 x 1200, in 24-bit color. Business professionals currently using high-resolution analog monitors, as well as users who plan to take advantage of increasingly popular digital flat panels, will benefit from the chip's 256-bit DualBus architecture. This well-balanced architecture powers razor-sharp, crystal-clear 2D graphics, even at taxing resolutions as high as 2048 x 1536 at 85 Hz, in 32-bit color on the primary display screen. And with two RAMDACs built directly into the chip, the Matrox G450 ensures a superior-quality analog output signal-not just to one, but to two displays simultaneously.
De verkleining van de die naar .18 micron moet ervoor zorgen dat de kaart op een hogere clocksnelheid kan lopen dan de G400, maar hoeveel hoger is nog niet bekend aangezien Matrox daar zelf nog niet helemaal uit is .
