A Closer Look

The HIS iCooler V heasink is an elaborate piece of cooling technology. Note how the baseplate cools the GPU and memory chips at the same time, but it still does not cover the whole area of the cooler base which helps to keep costs down. A central copper surface soaks up heat quickly from the GPU surface and transfers it to an array of fins where it is dissipated.


HIS has opted to stay with the 6+6 pin PCI-Express connector configuration used by AMD on their reference designs. While we have seen some AIBs use 6+8 pin this is not needed and pure marketing.


The GDDR5 memory chips are made by Samsung, and carry the model number K4G10325FE-HC04. They are specified to run at 2500 MHz (5000 MHz GDDR5 effective).


uP6213 is an affordable voltage regulator, unfortunately it does not support the I2C interface, so software voltage control is not possible.


This is AMD's Cypress GPU, it comes with a whopping 2154 million transistors and is produced on a 40 nm process at TMSC Taiwan. The Cypress die size is 334 mm².
