As we mentioned in HD 4870 review, Radeon HD 4870 have a very good graphic performance, but poor inÂ temperature/cooling and power consumption. Powercolor HD4870 PCS+ is the first non-reference 4870,Â and all of us are looking forward of this product, expecting it have a way better cooling. So when we got the card we did not run normal performance testing but instead ofÂ temperature test. We hope after a month’s preparation, AIB manufacturers introduce a product more better than reference HD 4870.
PowerColor HD 4870 PCS+ is based on reference 4870 PCB design, the major improvements including better voltage regulator module and cooling:
- VRM upgrade from 3 phase(reference 4870) to 4 phase; replaced reference cooler with ZEROtherm dual heatpipe cooler.
- Memory modules and VRM have their independent heat sink.
- Also Powercolor added a shiny metal strip to prevent PCB deformation.
What’s more, HD 4870 PCS+ is factory overclocked to 800/950MHz (core/memory) (reference: 750 MHz/900MHz) . After all these changes, Powercolor keeps the price tag only ten dollar higher then reference version (newegg price). On behalf of one Powercolor rep, the card is more perfect than reference design.
