AMD Radeon HD 6870
The AMD ATI Radeon HD 6870 measures 25cm long and weighs roughly 1kg. The GPU has been fabricated using the 40nm process, except it features 454 million less transistors than the Radeon HD 5870's Cypress XT core. This allowed AMD to shrink the die from 334mm2 to 255mm2, making the Radeon HD 6870 more fuel-efficient. The core is clocked at an impressive 900MHz, the HD 6870 has 1120 SPUs, 56 TAUs and 32 ROPs.
