We pair the Sapphire HD 7770 with another and see how CrossFire HD 7770 performance looks.

When I installed the Sapphire HD 7770 OC into my testbed and ran 3DMark 11, I found that there was only a few points difference between the score that Sapphire offered and what we saw out of the XFX HD 7770 Black Edition S Super Overclocked 1GB which we looked at the other day. Heading into GPU-Z I saw the reason the score was so close was because both cards where clocked extremely close to each other. We'll cover the clocks in the next page when we look at the specifications of the card.

Since it felt like a waste to just test the Sapphire card by itself when it's score would be near identical to the XFX model, I decided to pull the XFX card back out and throw it alongside our Sapphire one and see what CrossFire performance was like.

With the clocks on the card being similar but not identical, we lined up the clock speeds of the cards and then as always proceeded to benchmark them. Before we see the kind of performance we got, though, the first thing we need to do is take a closer look at the Sapphire card, which we haven't looked at yet.

The first thing we'll do is check out the package before we take a closer look at the card. Once that's done we'll cover the specifications of the OC model and go into a bit more detail what we did with the clocks. From there it's all about the performance of the setup, so with haste let's get into the package.



This is a really nice bundle for what is considered a mid-range card.

Alongside the included HDMI cable, the other big stand out is the Mini-DP to DP connector, which is something we're seeing a lot of companies ignore with the HD 7000 series.
