ATI Radeon HD 5830: The Slowest Cypress-Based Card

Radeon HD 5830 reference board

XFX Radeon HD 5830

The Radeon HD 5830 is AMD’s new product to fill the gap between the HD 5850 and the HD 5770.

The HD 5830 comes with half of the ROPs compared to the HD 5850 (32 ROPs). ROPs (Raster OPeration) are important because they do operations such as color blending and their number has a direct impact on performance.

The HD 5830 has the same memory performance than the HD 5850 and even offers better performance than the HD 5850 at the GPU level. But the higher GPU clock leads to a higher power consumption: the TDP (thermal design power) of the HD 5830 is 171W while the TDP of the HD 5850 is only 151W…

The HD 5830 uses the same design than the HD 5870

In term of OpenCL GPU computing power, the HD 5830 comes with 14 compute units (Radeon HD 5870: 20 and Radeon HD 5850: 18 – see HERE for more details about compute units)
