Powercolor HD 7870 Tahiti LE

post #1 of 9
Thread Starter 
I'm currently looking at this HD 7870 because I read somewhere that the Tahiti LE has better specs then the normal 7870 which uses pitcairn.

http://www.ncix.com/products/?sku=79571&vpn=AX7870%202GBD5-2DHP&manufacture=PowerColor&promoid=1313


Shows model number AX7870 2GBD5-2DHP

But I am having a really hard time finding out any info about this specific card. Do all Tahiti LE GPU's have the increased specs or is it only certain kinds? Does this model have the increased stream processors and other things?

yes its a different chip i'd mark it some where between a 7870 and a 7950. but much better than the original 7870.

its either going to be LE, or Myst

It's the same card as the AX7870 MYST with exception to the cooler which from my understanding is not quite as good. The card itself is good and should be able to reach 1100-1200MHz core although the memory is already clocked at 1500MHz and is not recommended to push it much if any further.

I like to think of them as 6970's on steroids seeing how they have the same amount of shaders at 1536. It's a 7950 with 1/4 the shaders cut. Like I said their good cards but temps can be an issue especially if their clocked over stock.

Just seems strange that it is supposed to be 1500mhz memory clock but that would be 6.0 gbps. But the card says right in the name it is a 4.8gbps which would be the standard 1200 mhz clock. Seems so much conflicting information it is hard to tell if it is actually a Tahiti LE or just a Pitcairn XT.

I can't find the exact model on the power color website either which seems strange. I guess i could send it back if it isn't what it is supposed to be confused.gif

Newegg has a standard Pitcairn XT powercolor on sale for 150$ and if this is actually the Tahiti LE then it would be a better buy for 160$.

Yea seems to me as if the core clock is correct but memory is the Pitcarin XT. I found that model # on Newegg and it is a Pitcairn XT.

http://www.newegg.com/Product/Product.aspx?Item=N82E16814131520

So it's either a mistake in that it's the wrong model # and memory speed or the core speed and labeling it a Tahiti LE is wrong.

Here is the link to the Tahiti LE version from Newegg as well.

http://www.newegg.com/Product/Product.aspx?Item=N82E16814131487

If you can call them I would do so and ask them directly because something is definitely off there.

Newegg does have refurbished 7870 Tahiti LE MYST for $135.

I was thinking it was mislabeled as well but checked forum messages and Ive found at least 4 posts with people saying they can verify it is Tahiti LE with GPU-Z. So it is a pretty good deal for 160$. But after some further looking around they have a Powercolor HD 7950 for 195$ after rebate.

http://www.ncix.com/products/?sku=84902&vpn=AX7950%203GBD5-2DHV5E&manufacture=PowerColor&promoid=1313

Is that model of 7950 worth an extra 35$ over a Tahiti LE?

That model is very similar to the PCS+ 7950's I have and actually flashed my bios to that model's. The 3gb of VRAM will serve you better at higher resolutions so it maybe worth it if gaming at 1080p or higher. I would say it worth it just because the cooler is way better than the Tahiti LE.

It's a shame because Newegg was selling these at $190 until they sold out.

It should also be noted that if you have preference to the color of the PCB that it may actually be red and not black.

Yeah the PCB color does not matter much to me. I have a bit of a blue/black theme going on but it is mostly just by coincidence. I think the 7950 is my best bet at 195$ so ill probably order one tomorrow since it even has free ground shipping. I was going to buy one a while back and hesitated to long and prices went back up but this is even less then I was expecting. I just want something that will work well for a few years.

My GTX 260 actually still worked fairly well for how old it was. Until it just kinda stopped working one day lol. This GT 220 backup is getting annoying. Thanks for the info/help.

Well the 7950 I was looking at ended up selling out before I had a chance to place my order so I ordered the HD 7870 Tahiti LE instead before they sold out as well. It is good enough for my needs and way less then I was planning to spend at 160$.

Is there any special preparations anyone recommends for dealing with drivers? Is simply uninstalling the Nvidia drivers from Programs and Features ok? I usually do a complete format when I get new hardware but I did it not that long ago and kind of want to wait.
