Alright, let's start of with pictures, below you can see the HIS Radeon HD 7770 1 GH edition. You can see packaging and bundle. Included with all cards will be manual and a demo and driver CD, power converters and an monitor connector converters to get your multi-monitor freak on.
The 1.5 Billion transistor encounting 28nm Cape Verde based core is tied to a decent 1GB memory -- which is a lot for entry level products. The R7770 is sitting in the 100 to 125 EUR price bracket.
The HIS 7770 1 GHZ card is clocked at a 1000 MHz core frequency and the GDDR5 memory runs at 4.5 Gbps (effective data rate as GDDR5 has a quad data-rate, so effectively that quadruples that number) the memory bus is 128-bit though. There is however a lot of room left for tweaking and overclocking as we'll demonstrate later on in this article.
