ATi has timed the start of its new Evergreen graphics chip with military exactness. It's the world's initial Direct X 11 chip so it is no concurrence that it was started simply in time for Windows 7.

The first editions of Evergreen to hit the environments are the high-end HD 5850 and HD 5870 which as the model codes propose are substitutes for the Direct X 10.1 HD 4850 and HD 4890. The HIS Digital HD 5870 that we're analyzing is a mention design with an HIS sticker on the cooler and a voucher to actuate a copy of Colin McRae Dirt 2 on Steam when the game is issued more recent this year.

The graphics card are normal of HD 5870 graphics cards that you will also check from Gigabyte, Power Color, Sapphire, XFX and others. contribute it a month or so and we will check updated designs with tradition coolers and raised clock speeds.

HD 5870 supports Direct X 11 which is a substantial step advancing from Direct X 10.1 but the new chip has some other trick up its sleeve. HD 5870 uses the similar 40nm construction procedure that was inserted with HD 4770. cutting the size of each transistor has granted ATi to double the number of Stream CPUs or mingled Shaders with only a slight increase in the size of the chip.

The 55nm HD 4870 and HD 4890had 800 Stream CPUs and needed a die size of 263mm2 to house the 956 million transistors. By differ the new 40nm HD 5870 has 1,600 Shades and 2.15 billion transistors in a die field of 334mm2 which is an increase in area of 27 percent. The not rather king of the heap HD 5850 has 1,440 Shaders in a chip that is the similar size as HD 5870 so we can derive that one block of Shaders has been disabled.
