AMD's Radeon HD 4870 X2 dual-core card can handle more than 2 trillion instructions per second, delivering higher quality and image resolution than Nvidia's products.

HD 4870 X2 is capable of handling three times the single-core HD 4870 and sells for $ 549. The device is equipped with 2 gigabytes of ultra-high bandwidth GDDR5 memory and each GPU, using CrossFire X technology, reaches 750 MHz clock.

However, users can wait until September when AMD introduces a 625 MHz HD 4850 X2 version, which works slower than 4870 but only costs $ 339.

AMD's main rival in the field of graphics processors is Nvidia with Nvidia 9800GX2, the highest-end product.
