A Closer Look

The cooler looks fairly simple. It manages to keep the card cool without any fancy heatpipes or expensive copper baseplate. Nevertheless the cooling performance is good, thanks to the low heat output of ATI's latest GPUs. The yellow fan is made by Arctic Cooling which is almost a promise for low-noise, high-quality cooling performance.


Unlike the reference designs, the AXLE HD 5670 requires a single 6-pin power connector. Looking at our power consumption data, I can't see any reason why AXLE added that to their card.


The GDDR5 memory chips are made by Hynix, and carry the model number H5GQ1H24MFR-T0C. They are specified to run at 1000 MHz (4000 MHz GDDR5 effective).


The voltage regulator in use is a uPI uP6201 which doesn't feature software voltage control, but that's not a big problem for a card in this performance class.


AMD's Redwood GPU comes with 627 million transistors and is produced on a 40 nm process at TSMC Taiwan. The die size is 104 mm².
