ATI Radeon HD 5870 gets dismantled

Techpowerup found photos and the specifications of ATI's upcoming Radeon HD 5800 series graphics cards. The Radeon HD 5870 features a 338mm² 40nm GPU that contains 2.1 billion transistors, more than double as much as the RV790.

Here are some of the specifications and the prices of the three Radeon HD 5800 series SKUs that will be launched on September 23rd:

Finally, information from ArabHardware.net suggests a pricing model on three of the first SKUs based on Cypress: HD 5870 2 GB, HD 5870 1 GB, and HD 5850 1 GB. All three use the same GPU and memory standard (GDDR5), but differ in clock speeds and GPU configurations. While HD 5870 sports 1600 stream processors, 80 TMUs, and 32 ROPs, HD 5850 has 1440 stream processors, 72 TMUs, and 32 ROPs. Although 32 ROPs puzzles us for a 256-bit wide memory interface, we suspect low-level design changes that make "32 ROPs" more of an effective count than an absolute count. While HD 5870 features over 800 MHz core clock and 5.20 GHz memory, its little sibling has over 700 MHz core clock and 4.40 GHz memory. Price points expected are US $449 for Radeon HD 5870 2 GB, $399 for HD 5870 1 GB, and $299 for HD 5850.
