You're not going to see anything too exciting with the reference HD 7750.
We've got a heatsink fan over our core which takes just a single slot up and we've got no external power connector CrossFire Bridge. On the I/O side of things we've got a Dual-Link DVI port alongside a HDMI and DisplayPort connector.
Since our HIS HD 7750 carried with it the reference clocks, there's no real surprise here when it comes to the numbers we're looking at. You can see the core clock speed comes in at 800MHz while the 1GB of GDDR5 carries a clock speed of 4500MHz QDR.
Before we get into the testbed side of things and the cards we'll be comparing today the last thing we want to do is make sure that CrossFire is working. Looking above it seems to be as we can see it's enabled via 2 GPUs.
The best way to find out everything is going along well, though, is to run 3DMark 11, which we'll do in just a second.
