The Juniper Pro chip was manufactured in Taiwan on the 13th week of 2011.
As opposed to the GPUs of the ASUS and Gigabyte cards discussed above, this one has only 720 unified shader processors, 36 texture-mapping units and 16 raster operators. The GPU clock rate is only 700 MHz in 3D applications and is lowered to 157 MHz in 2D mode. There are heatsinks on the memory chips, so we couldn’t read their markings. We can only tell you that the card’s memory clock rate is 4600 MHz whereas the total memory amount is 1 gigabyte.
PowerColor’s cooling system doesn't have a proper name. It is designed in a very simple way. It has a copper base with four copper heat pipes, 6 millimeters in diameter. There are slim aluminum fins on those pipes, placed 3.5 to 4 mm apart from each other.
The fins are press-fitted on the pipes which are soldered to the base.
Despite the simplicity of design, the cooling system copes well, keeping the GPU temperature under 55°C.
You should keep it in mind that the Juniper Pro's clock rate is 150 MHz lower than the clock rate of the Juniper XT chips the previous two cards are based on. Is the passive cooler of the PowerColor card any good at overclocking? Yes, it is.
The GPU is only 59°C hot when the card is overclocked to 855/4880 MHz.
Now let’s move on to our performance tests.
