A Closer Look

HIS uses a fairly simple heatsink which is just a big chunk of metal with some cooling fins. AMD's latest generation of graphics processors consumes extremely little power, so there is no need for elaborate cooling solutions.


Like all other HD 5450 cards, the HIS HD 5450 requires no additional power connector. All power is supplied via the PCI-Express bus.


The GDDR3 memory chips are made by an unknown manufacturer and have been relabeled to say "ATI". According to the markings the chips are specified to run at 1.2 ns, at 833 MHz (1666 MHz GDDR3 effective).


uP6101 is an affordable voltage regulator that does well on less complex cards. It does not support the I2C interface, so software voltage control is not possible.


This is AMD's Cedar GPU, it comes with 292 million transistors and is produced on a 40 nm process at TSMC Taiwan. The die size is 59 mm² - really tiny!
