HD 7850 vs 7870?

post #1 of 35

Thread Starter 
Hey everybody, I was looking at getting a 7870, but I can't help but feel like it is a worse value compared to the 7850. I'm not sure if the performance increase is worth the 100+ extra bucks. It seems like the 7870 is about 10% faster, or less, in most cases.

I am looking at this same decision here in a few weeks

This is a nice comparison of the two cards.

I may go with a 7850 reference in hopes it unlocks but then again I may not take the chance on that and just get a 7870

I'd say save the $100 and down the road if you see it necessary, get another one for xfire thumb.gif

The HD 7800 series is not well priced curently. If you can afford USD 400 go for Sapphire HD 7950 OC. You can get this card to 1100 at stock volts. with sapphire trixx and extra voltage 1200+ is achievable. Even HD 7870 at 1200 Mhz will be much much slower. thumb.gif

Agree for the most part. 7850 at $220-250 is a good value and if oc'd performs very well while sipping power. But the 7870 is priced to close to the 7950 and 670, which both perform much better. I actually just ordered a sapphire 7850 to replace my unlocked 6950 in my htpc. Wanted something that took up less space, created less heat and performed about the same or better.

What kind of power supply is needed to crossfire 7850s?

650 should be fine for a CF. It'll really depend on your extra components but for the most part I think you can get away with a 550W(good quality of course) with 7850 CF.

I'd recommend Corsair professional series PSUs. they're really good and the modular black cables that come with it make them all the better:thumb:

I dont guess its worth it from a performance to dollar standpoint but if youve got the extra $100 to spare, I think you should go ahead and get the 7870. Im a big believer in getting as much GPU horsepower as you can afford. Games are slowly getting more demanding and the more GPU muscle you have, the better performance youll get and the longer youll be able to go without needing an upgrade.
