Exclusive: XFX HD4770 Review

[desiibond]

hmm okay.

how about this:

The architecture of HD4770 and HD4850 is almost the same. And the things that are less in HD4770 is 128-bit memory bus width and 193MHz slower Memory clock and 160 less shaders.

Now, HD4770 has faster core clock, lot lot faster GDDR5 RAM. As a result of this, it was only a bit slower than HD4850. Now, when I increase core clock even higher and Memory clock made same/higher as/than that in HD4850, HD4770 should be lot more faster than HD4850 because it has faster RAM, faster memory clock and faster core clock. This should be the reason why for small increments in clock, we are seeing high increase in fps.

^^To beat HD4850 full on, set to following parameters:-

Core - 800MHz(50MHz only!)
Memory - 1000MHz(check the chips, they ARE RATED TO RUN AT 1000MHz, 1.0ns chips)

1Ghz memory on HD 4770 surely boosts the FPS in all the games ,,

@ desiibond : in some games only HD 4770 lows on to the HD 4850 many games its equal may be if u change ur proccy then u ll get more FPS !!

@desiibond

is ur Sapphire HD4770 a dual slot card??

 

[desiibond]

nope. Sapphire's is not a dual slot card but it's cooler is big and luckily, it nearly touches the soundcard in PCI slot. Will post a detailed picture in the morning.

and it seems a dual slot, but is not fully covered, and has a big copper heatsink. but it leave the air inside the chassis itself.
