Radeon 5770 vs Radeon 4890 - Page 2 - Overclock.net

**ericeod** · 10-20-09

The 4890 outperforms the 5770. The 5770 is more on par with the 4870. But the 5770 runs more efficient with a die shrink, runs cooler and supports DX11. So take that for what it is worth.

Last I checked, some 4890's can go over 1ghz core

Yea, some. Most top out at around 960-980 and less than 1200 memory. I am saying I have reached the bios limit of 960/1445 and it is not even getting hot enough for the auto fan to turn itself up. As soon as I get this BIOS limit bypassed, we will see how high it can go, but for now I'd say that constitutes as a higher OC potential.

I will check if the ASUS 5770 I ordered has higher OC potential. I know their 5850 and 5870 can go higher due to ASUS own OCing software and voltage control.

4890 is still better than the 5770 as of now. IMO, it's much better to go for a 5850 if you're going for a single card setup or at least wait for Fermi/5900.

I was really interested in a 5770 for my AMD system. But it just does not have the power to cost $160. It should beat 4870 1GB and trade punches with the 4890. But in truth, it doesn't even beat a 4870 512mb half the time.

4890 stock is faster than 5770 stock, but both are known to be great OCers.

5770 is cheaper @TM IIRC and has DX11, less power/heat, AA/AF methods, etc. + It can easily be OC'd to 4890 levels and beyond. On early drivers it's about on par w/ the 4870 IIRC.

If not a 5770, then save for a 5850.

edit:
Currently owning a 4890 I would not currently buy a 5770. However if I had a 4850 or less(performance-wise) and was looking to upgrade I'd def. have the 5770 near or @ the top of my list.

the 4890 is faster but then again the 5770 supports dx11.
By late 2010 we will probably see the first dx11 games

Hey - thats decent!

Tell me something real quick - the heatsink for these cards also cool RAM. Corrent?
