The matter of the fact here is that its a 40nm card and cheaper in comparison to 4870 and 4890 and we can never pick up a card just for playing single games. NVIDIA favors some and ATI favors some , so its a never ending debate. The crux here is that ATI have made a low cost solution which is powerful enough and things are going in right direction as more will follow. it is just a beginning and i hope to see NVIDIA goin the same way soon as it also saves the environment!!!!I hope all of you would agree

Power Consumption for GTX 275

We'll now show you some tests we have done on overall power consumption of the PC.

The methodology is simple: We have a watt monitor constantly monitoring the power draw from the PC. We look at the recorded maximum WATT peak; and that's the bulls-eye you need to observe as the power peak is extremely important. Bear in mind that you are not looking at the power consumption of the graphics card, but the consumption of the entire PC. From a performance versus wattage point of view, the power consumption is pretty good with the new 55nm products.

Note: we recently upgraded our test-platform, which by itself utilizes a lot of energy.

It's Core i7 965 / X58 based and overclocked to 3.7 GHz. Next to that we have energy saving functions disabled for this motherboard and processor (to ensure consistent benchmark results).

The ASUS motherboard also allows adding power phases for stability, which we enabled as well. I'd say on average we are using roughly 50 to 100 Watts more than a standard PC due to these settings and added CPU overclock. Keep that in mind. Our normal system power consumption is much higher than your average system.

* System in IDLE = ~210 Watts

* System with GPU in FULL Stress = ~396 Watts

The monitoring device is reporting a maximum system wattage peak at roughly ~400 Watts, and for a PC with this high-end card, this is excessive but remains within acceptable levels.

The IDLE Wattage is fine, though a little higher than the competition. Again, this test PC consumes heaps of power.

The ASUS motherboard allows adding power phases for stability, which we enabled as well. When you take everything into account, I'd say on average we are using roughly 50 to 100 Watts more than a standard core 2 duo based PC due to these settings and added CPU overclock. Keep that in mind.

Our normal system power consumption is higher than your average system. The results:

* System in Idle: 232 W

* GPU stressed 100% : 305 W

Roughly 305 Watt, which is really fine. 305-232 = 73W which rhymes well with the 80W TDP ATI claims.


I think still the CF setup is still less pricey and more energy efficient..

Please feel free to comment here.

whats the point in winning by a single fps when the CF setup will limp around like a 3-legged dog?

agreed,.single card setup is definitely better than crossfire. but check out its performance in rest of the games in the review. 4770 CF leads in almost all games.

moreover,.couple of 4770's will cost you 13k (excluding the cost of a CF motherbaord + PSU) while gtx 275 will easily be around 20k and other cards in the review will average around 15k. so even if 4770 is better by 1 fps,..it hugely increases the price:performance ratio.
 
^^yes i agree...hell, i gotta buy a mobo with CF...do you think the VX450 can handle 2 of these cards :)

i guess vx450 can handle 2 of those!

even CM extreme 600W can handle 2x HD4850 CF!! :D

Actually VX450 was never touted as a CF/SLI ready PSU but with such low power consumption from a CF setup its now a good CF PSU indeed.... :hap2:
 
crossfire drivers are PITA . i was using 4850x2 before and the card was fine with stock drivers , once i updated drivers had so much problems with vista disabling the second card and crossfire not getting enabled , also tearing and weird issues in crysis DX10 and bugs in many other games . would never go for crossfire again even if its 2x cheaper :| .

now switched to SLI and its working without any problems , just installed card and drivers and working gr8 . nvidia driver support rocks.

see then no of problems people having with crossfire :rofl: in ati forum

Another good review..

Legion Hardware
^ 4770 CF beats GTX 285 in COD World at War, Fallout 3, ETQW and Supreme Commander.

It beats 4890/275 in H.A.W.X, WIC, Soviet Assault and Crysis.
Awsome CF scaling with 4770..:)

Nope buddy, i seriously doubt that. Running 4850 CF on CM EP 600 would be kind of a Time Bomb .. :bomb:
 
^ they used DX9 :rofl: maybe they got CF problems with dx10 :P

and all those games dont stress gpu much , they should test GTA 4 etc ,in new games which use 1gb memory ,sometimes crossfire setup is worse than 1gb 4870 :rofl: also they didnt mention minimum fps ( which drops sometimes to 0 in CF setup )

anyway single 4770 rocks , but would be better to get 4890 instead of CF 4770 :)
 
^ i don't think, there is any CF Scaling problem in DX 10, had it, then FarCry2, Crysis, Stalker CS, etc won't scale. Still, Drivers for 4770 hasn't been polished yet. Hope to see further more scaling with Cat 9.5..

Yes, 4770 CF does struggle when AA is raised prolly coz of limited bandwith and only 512MBmemory buffer per GPU .:)

That shouldnt be a problem, as the GDDR5 memory bandwith compensates for the 128 bit bus. Also if I remember correctly, CF used the alternate screen rendering, as well as rendering by area. Rendering by area should not be memory limited, as it basically reduces the pixels to be rendered by each card. Thats where the limitations of multi-gpu setups are, they need to be optimized for each games individually.

Rendering screen wise, might be memory starved because each screen needs to be stored, as the cards would be rendering alternate screens. I think this is where the cpu cycle would have an advantage.
