Introduction

Earlier in the month we had a chance to look at the new PowerColor HD 7870 2GB Myst Edition Tahiti LE based HD 7870 which uses a modified version of the higher end Tahiti HD 7900 GPU. We found ourselves extremely impressed with the new model, but it was not without its flaws.

 

The card itself was excellent in so many ways and it was rounded off with a really strong price. The big issue comes from the marketing side of things. As we mentioned in that review the new Tahiti LE based HD 7870 isn't a model that AMD are promoting. Instead only certain companies are offering the model with PowerColor being one, and another being Sapphire.

 

Due to this it's up to companies themselves to promote it and while they'll do a pretty good job, there's no denying that the product won't get the same attention verse a model that every AMD partner was promoting. Since we've already looked at one of the new Tahiti LE based HD 7870's at its out of the box speeds, we'll today be taking time to overclock a Sapphire model to see just what it's capable of doing.

 

As always there are a few things we need to do before we get into the overclocking side of things. We'll start with the package to see what Sapphire is offering before we move onto the video card itself. Once we've done that we'll take a look at the specifications of the card out of the box before we look at how we went with the overclocking. Finally we'll quickly check out our testbed and then get into the performance side of things.

Having a look at the box there's nothing too new. You can actually see we're dealing with the typical HD 7870 box with just a sticker that gives it the new name which has the XT label tagged onto the end. The biggest problem is that we don't really know this card is based on the new Tahiti LE core. This was the same issue we noted with the PowerColor version that we looked at previously.

 

We kind of understand when you throw the "LE" tag onto anything it gets hit with this negative stigma. The difference is that this time we're dealing with a HD 7900 series core that has been brought down to the HD 7800 series level. In the past we often saw the LE tag on video cards in the same series where a lower end version of the core was used.

 

This time, though, we're dealing with a core that is used on the series above it and AMD have brought it down to the series below making it the highest end HD 7800 based video card on sale.

Looking inside the package it comes as a big surprise just how much there is contained within. Alongside the normal paperwork and driver CD we have the standard DVI to VGA connector and CrossFire bridge in the bundle. We've also got two Molex to 6-pin PCIe connectors, Mini DP to DisplayPort, HDMI to DVI and a full length HDMI cable to round things off. This package bucks the trend of late of light video card bundles.
