To test power consumption today we are using a Keithley Integra unit and we measure power consumption from the VGA card inputs, not the system wide drain. We measure results while gaming in Tomb Raider and the synthetic stress test Furmark and record both results.
Power consumption is good – holding at around 190 watts when gaming. Our R9 280X sample consumes around 210 watts by comparison – so clearly the new architecture has improved the situation. That said, Nvidia are still miles ahead – their cards consume a lot less power under load.

The latest AOC AGON monitor boasts a whopping 520Hz refresh rate
AGON by AOC is raising the bar again with its latest creation: the AGON Pro AG276FK. This 27-inch Full HD gaming monitor boasts a Fast IPS panel and an astonishing refresh rate of 520Hz, making it one of the first monitors with these specs to be released.
I agree with what was said on the pricing. Why buy this right now when you can get good deals on R9 280s?
It’s a replacement for the 280…so the price diff will only last as long as the 280s last.
Hmm, the KitGuru noise guide is a bit low on the decibels. And holy crap, I just realized how energy efficient the 750 ti is compared to its sadly low power :/ If only all cards wasted that few watts 🙁
This is a clear and concise review one of the best I’ve come across. Your use of similarly OC AIB customs leaves the reader not conjecturing like so many that went reference 760’s.
The 285 is a fine substitution for the 280, and while there’s still great deals on a lot of the 280’s, yes you’d have to quandary in which to go with. If your one to kind of think of a C-F in the near term, I’d say a 285 as it including CrossFire XDMA might make a strong contention (like to see C-F 280’s vs. 285’s). I think if I recognized I wasn’t predicting a monitor upgrade (1440p) during the life of the card, the choice of improved tessellation performance, along with it quad-shader layout, allowing four primitives to be rendered per clock cycle instead of two might be more useful as more titles evolve. Lower power is good, while I don’t see the whole memory @1080p add any apprehension.
It’s a hard call on the AMD side between (they win either way)… but consigns the 760 as no longer any smart deal. Then with Nvidia saying “nothing” as to its’ pricing, while bring it’s big brother into the fight with its price drop, one can pretty much figure Nvidia will let the 760 go quietly into the night.
Look at the 750Ti as the “5670” for the mainstream resolution today, just as the 5670 the no aux-power choice when 1680×1050 was in vogue. Given @1080p with the setting at medium is more its place to keep from “slide show” Fps, judging it in with this group is frivolous. Look at similarly OC customs of a 750Ti and 260X when gaming, the 260X needs 20% more while neither offer any difference in settings or immersion.
It’s nice to save power during 2-3 hours of gaming, but if you sleep (monitor off) AMD ZeroCore drops to 2-3W, while the 750Ti draws 5-7W when no one is using it perhaps 18 hours a day! If you really look at the total efficiency over a month’s power usage that saving is not all that pronounced.
