I guess you aren't into overclocking your video cards and CPU.

700 watts is fine for a NON-overclocked 295X2 and non-OC'd CPU.

Start OC'ing just the 295X2 and you are looking at 750 to 760 watts. Throw in CPU OC and a number of common devices, and you will easily be over 1000W.

Point being, you are looking at a system that requires twice as big a PSU, not to mention electricity, which isn't free.

I thought you were supporting the people attacking him for explaining the difference between SP & DP. Those OpenCL tests do not show NVIDIA cards in the best light for obvious reasons.

Oh and like I said earlier, other than the 12GB RAM, Titan X truly is a 780 TI successor. Not a true Titan successor. thumb.gif

I'm looking forward to the X80 with 6GB RAM for $649, so I can finally upgrade. wheee.gif

Once you get to the point of dropping $1,000 on a single GPU you shouldn't be that put off from the PSU requirements and the electricity draw of the R9 295X2.

Keep in mind that the Titan X is already around the amount of energy that the 290x uses at stock. We all know except for GM107 and GM206 that Maxwell throws its great efficiency away as soon as you do some pretty hefty overclocks.

Man this card looks really good , it might be time to retire my 780SLI and grab one of those but I'm definitely waiting for a waterblock.
Wonder how this would fare against 780SLI in terms of performance thinking.gif I guess nice boost in games with poor SLI support but slight loss in those with good SLI profiles.

295x2 on Newegg looks to be around $700 and you can get a 1300w PSU for under $200, still $100 cheaper than a Titan X. Or if you get a good deal, $600 for 295x2 and $150 for the PSU:

That is because for AMD to push the same performance they needed more power and more heat.
This card is what? Almost 50% more powerful than the 290x? So same power and same heat, but more power?

See the little difference?

The die is 37% larger as well.

Delta between Titan X and R9 290X2 average consumption is 207W

207W x 8 Hours a day x 365 days = 604.44 kWh/year

Even if we assume a high cost of $.30 per kWh, 604.44kWh/year * $0.30/kWh = $181.33 premium for running R9 295X2 over the Titan X all year at 8 hours a day...

Considering the R9 295X2 is currently $700, it will take about 1 year 7 months and 25 days of running the cards at load for 8 hours a days before the Titan X becomes a better economic strictly from an electricity cost prospective.

Also, good luck overclocking the Titan X, most reviews found it rather limited on the stock cooler...
