The first of the 28nm generation.
As the whole PC community was partying last December when the AMD HD 7970s were out for review, our invitation was misplaced as the test unit AMD was supposed to send us didn’t come through until two weeks back. As such, I decided to wait for a retail HD 7970 to review the card. Finally ASUS came through with their standard HD 7970, and today I’ll be looking at stock and CrossFire HD 7970 performance.
For those of you who still don’t know the hoopla surrounding the AMD HD 7970, here’s a quick primer on the new Radeon architecture. First of all, it’s the first graphics card to use a 28nm GPU core, the smaller size bringing with it lesser heat dissipation and lower power consumption. Secondly the HD 7970 uses AMD’s new Graphics Core Next (GCN) architecture which is a multi-purpose computation processor designed to handle various applications (not just games) of today and tomorrow.
The HD 7970 is the first implementation of the GCN architecture with double the L2 cache over previous generation VLIW4 architecture. This allows for a massive 2TBps bandwidth capacity across the core of the HD 7970.
The rest of the technical specs can be seen on the chart below:
Now let’s talk about the ASUS HD 7970 that I’ll be reviewing.
The packaging is standard fare for ASUS, nothing overly flashy on the box. Inside we have a manual, driver CD which comes with the ASUS GPU Tweak utility, a HDMI to DVI and a mini-DP to DVI cable. Furthermore we have a 6-pin power cable along with a CrossFireX bridge.
