8800GTS 512 vs 3870 power consumption?

post #1 of 8
Thread Starter 
I don't need to know which is better, I just need to know if the 8800 consumes less or more than the 3870.
post #2 of 8
hmm...I would think the HD3870 consumes less power, because it has a lower fabrication process.

The 8800GTS 512 consumes about 30 watts more power, uder load, than the 8800GT or Radeon 3870.

8800GTS is a beast, and will consume way more power than the 3870. Although the 3870 has powerplay, which lowers the core clock to 300mhz every chance it gets, regardless of whether or not you want it to, and as of Catalyst 8.2 they have yet to add an option to disable it. I emailed AMD about it and said they they "had someone looking into it".

The difference is pretty minimal, unnoticeable, and with your PSU you'll be fine.

3870 is probably the most efficient though and I've even further lowered my 2d clocks in the bios.

overclock it using riva tuner or simply enable low level overclocking and it will stay at the 3D clocks.
adding,8800gt consumes lesser power than 3870 at load.
