ATI has just recently published a new beta for their Stream SDK, a package designed to assist developers in creating GPGPU apps for ATI graphics adapters. The new package primarily adds OpenCL 1.0 support and, while all of that is well and good, it has also tipped the firm’s hand by revealing evidence of the Radeon HD 5900 series.
A quick peek at the new INF file for the SDK-compatible GPU driver lists the following entries:
“ATI Radeon HD 5900 Series” = ati2mtag_Evergreen, PCI\VEN_1002&DEV_689C
“EG CEDAR” = ati2mtag_Evergreen, PCI\VEN_1002&DEV_68E8
“EG CYPRESS” = ati2mtag_EvergreenGL, PCI\VEN_1002&DEV_6888
“EG JUNIPER” = ati2mtag_EvergreenGL, PCI\VEN_1002&DEV_68A8
“EG REDWOOD ” = ati2mtag_Evergreen, PCI\VEN_1002&DEV_68DE
What the 5900 constitutes is anyone’s guess. If history is any indicator, it should be a juiced-up version of the 5870 with higher frequencies as a result of improved yields.
Rounding out the list, we see Cypress (Radeon HD 5870/5850), Juniper (Radeon HD 5770/5750), and Cedar and Redwood which have not yet shown in the market. Those cards are believed to be low-end adapters suitable for the OEM channel.
