6870 vs 7870

post #1 of 13
Thread Starter 
I am looking at building a second computer to be used as a family multi-purpose computer for games and browsing.
The computer will be an i3 cpu 4gb/8gb ram with 1tb hard drive
the psu is undecided
I already have 4gb of spare ram from my own computer as i have 12gb which i will never use....
i already have a ati hd 6860.
i was wondering if i should either get another 6870 for the second computer as i have not found any games i cant play. however the price difference between 6870 and the 7870 is only £50 so i was wondering if i would see any real world difference if i put my current 6870 in the new build and bought a 7870 for my personal computer?

This sounds like a good idea, 20-30% faster looking at some benchmarks and game FPS.

Go for the HD 7870 Tahiti LE. comes with 1536 stream processors at 975 mhz. 256 bit memory at 6 Ghz (192 Gb/s) . around 10% faster than HD 7870. Sapphire HD 7870 XT is one of the best Tahiti LE cards. good cooler. when overclocked to 1.2 Ghz matches HD 7970(925 mhz)

http://www.overclockers.co.uk/showproduct.php?prodid=GX-312-SP

you can see users have posted benchmark comparisons with HD 7950 too.

close to 60% faster than HD 6870 at stock speeds. with overclocking to 1.2+ Ghz you will mostly be doubling performance. comes with 2 AAA games - bioshock infinite and tombraider thumb.gif

lots of good information about the graphics card you suggested, howerver i am looking at buying the cheaper xfx version of the card as i dont really want to be spending £200 on a graphics card. This is because i dont really need a new graphics card for my pc but i was thinking i could upgrade my computer for a small amount (£40) difference to what i would be paying to put a 6870 into the second computer.
but rep for the helpful information smile.gif

if you want a slightly cheaper card go for powercolor pcs+ myst hd 7870 (tahiti le) for 180 pounds . free delivery. cooler is louder than the sapphire hd 7870 xt.

7870 will most certainly be an upgrade, yet an i3 would be the biggest bottleneck you can strangle 7870's bandwidth demands with. Why not pick an FX 6300? Don't overlook its crossfire performance when installing a single card, what it can handle twice over will definitely benefit the minimal latency of a single card.
Crysis 3 benefits from the 6 cores, hence correlates with multicore beneficience even more so than the Frostbite 2 engine(it supports 5 threads afaik).

Just take a look at those charts.

wow, really helpful.... one graph out of a 27 page article, a graph that gives a score, Where did i say i wanted to increase scores? i dont even know what the scores mean. Yes i know that they give an idea on which cards better than which, but it doesnt really tell ME anything about the card. I understand that you are trying to be helpful but could you please try to be friendlier about it instead of linking an article that is to do with a card that has a similar name 7870 7970 very easy to get the two mixed up, so i assumed this may have been what you have done. Also when im looking at a £160-£180 card i dont want to go through a massive article about the card above it.
maybe next time just quote the relevant information?

The computer that the 7870 will be going in is an i5 2500k not an i3, the i3 will be in the new computer that will be getting my old graphics card or a new 6870 depending on my decision.

my friend has the 6870 and i have the 7870 and as far as we can tell the bottle neck is going to be the Cpu for sure i have the fx 8120 and he has the 8150 and he scores only about 5 -10 fps lower then me but bang for your buck the Xfx 7870 is cheaper then some of the other cards out there it runs hotter but is nice and quite that is the trade off but it does have more kick then the 6870 if your looking for somthing that is going to be good for another year or 2 depending on the gaming that you do i suggest the 7870 it is the best bang for the buck now a days and you will hear that on alot of reviews it is the best price to performance ratio of all the ati cards currently in that price range good luck with your choice and always remember it is your cmputer get what you want and game on buddy thumb.gif
