Radeon HD 5570
This model is based on the Redwood (Pro) graphics chip, which is used in the production of serial HD 5670, however, unlike the "older" adapter, the HD 5570 works with DDR3 memory up to 1 GB. The memory bus remains 128-bit, and the thermal package of the novelty, thanks to the use of a 40-nm technological standard, does not exceed 42.7 W at the recommended frequencies of 650/900 (1800) MHz.
“Saturated” with 400 stream processors, 20 texture units and 8 ROPs, the new video accelerator requires active cooling, especially since it is made on a low-profile printed circuit board and it is problematic to fix a large heatsink on it. The interface panel contains DVI, D-Sub and HDMI video outputs. The latter can be replaced by DisplayPort depending on the policy of a particular vendor. On the back side there are four DDR3 chips and a backplate.

The Radeon HD 5570 starts at $79. Unfortunately, as practical tests have shown, the use of slower memory seriously limits the capabilities of the Radeon HD 5570 - in games it is minimally inferior to the representative of the previous generation HD 4670.
