Boo-ya! We review the world's first 40nm graphics card - the XFX HD 4770
Great performance, custom cooler, good overclocker, low power consumption
No overclocking software, occupies two slots, expensive

40nm fabrication is finally commercial and for the first time it's a GPU instead of a CPU, and who other than ATI to bring you the world's first 40nm graphics card.
After striking gold with their 55nm RV770 GPU back in August last year, the RV740 is finally a reality. Shrinking the die further means cheaper cost of production (though the fabrication process itself is more expensive initially at least) since you get more dies per wafer of silicon and also lower power consumption, which eventually gives you lower operating temperatures.
The RV740 is not architecturally very different from the RV770; in fact it supports the exact same features. This GPU is fabricated using the 40nm process and comes with 640 stream processors (or shaders) just like the HD4830. In order to lower the cost of the card, the memory bus has been cut down to 128-bit instead of 256-bit, but to compensate for that ATI has chosen GDDR5 memory which is relatively easy to implement while drawing less power (1.5v). So instead of just shrinking the die of the HD4830, ATI has taken a slightly different route by giving you low voltage and much faster GDDR5 memory coupled with higher clock speeds for better performance.
The HD4830 was never far behind from the HD4850 and now with the HD4770 replacing it and promising better performance, that gap is soon closing up. We managed to snap up the only retail sample of the XFX HD4770 available in the country and are going to compare it with the reference card to find out what XFX has done differently. The direct competition to the HD4770 from Nvidia is the 9800GT, so of course that's there, and then we have the HD4830 and the HD4850 to complete the group.
Can anyone tell me where can I buy it in Pune? I am not able to find even ATI cards in some of the prominent shops in Pune. I was actaully looking for 4850, but I think this one looks better.
could i attach this graphic card with my asus (m2a-mx) motherboard,
i really need ur help,
i m new in this matter.
athor brand of this card are:-
MSI, HIS, Sapphire, Diamond, Gigabyte & Powercolor
which one is the best
please help me please......
You can definitely use the card on that mobo without any performance loss since its a midrange card. Right now, MSI seems to have a very competitive pricing of around 6.5K (in Delhi at least) so if you can find one for similar pricing, its a steal.
hiii,sir i have a intex-4800 watts subwoofer,but i want its sound quality features,life,how's experience compatibility of 5.1 channel home theatre system,so pls give more information about it.
Well, i got one, the Diamond 4770 at Frys here in the USA. It is kinda a high price, but since May all prices went up on Disk & Video about 10%.
Issue is it needs newer drivers, 9.4 does not seem to load for it. it seems slick, i'll be testing it out and comparing to 4850.
congrates for bringing the first available retail card review. You should consider that a modest testbench while reviewing a mass market graphics card. This will give more appropriate understanding of how the card will perform on an average joe's pc.
keep up your good work :)
Nice review and test system but I think the appropriate nvidia card to use as comparison would be the 9600GT and not the 9800GT.
When you're not comparing the "cream-of-the-crop" "monies no issue" components it more comes down to "bang-for-the-buck". The current price of the HD4770, here in Canada is $130.00 so also the 9600GT at $130.00 but the 9800GT is retailing at $160.00.
Also, to be fair, the nvidia comparison card should have been over-clocked to show it's maximum potential.
