NVIDIA's list of CUDA-enabled products

I would like to make an 'overview' for GTX 6xx / 7xx series graphic cards:

Graphic card = Prize (US market) = Wattage = RAC (for the beginning maybe with/of SAH Enhanced Cr., we have experiences with them)


GTX 650
384 CUDA Cores
1058 Base Clock (MHz)
5.0 Gbps Memory Clock
64 W Maximum Graphics Card Power

GTX 650 Ti
768 CUDA Cores
928 Base Clock (MHz)
5.4 Gbps Memory Clock
110 W Maximum Graphics Card Power

GTX 650 Ti BOOST
768 CUDA Cores
980 Base Clock (MHz)
1033 Boost Clock (MHz)
6.0 Gbps Memory Clock
134 W Maximum Graphics Card Power

GTX 660
960 CUDA Cores
980 Base Clock (MHz)
1033 Boost Clock (MHz)
6.0 Gbps Memory Clock
140 W Maximum Graphics Card Power

GTX 660 Ti
1344 CUDA Cores
915 Base Clock (MHz)
980 Boost Clock (MHz)
6.0 Gbps Memory Clock
150 W Maximum Graphics Card Power

GTX 670
1344 CUDA Cores
915 Base Clock (MHz)
980 Boost Clock (MHz)
6.0 Gbps Memory Clock
170 W Maximum Graphics Card Power

GTX 680
1536 CUDA Cores
1006 Base Clock (MHz)
1058 Boost Clock (MHz)
6.0 Gbps Memory Speed
195 W Maximum Graphics Card Power

GTX 690
3072 CUDA Cores
915 Base Clock (MHz)
1019 Boost Clock (MHz)
6.0 Gbps Memory Speed
300 W Maximum Graphics Card Power

GTX 770
1536 CUDA Cores
1046 Base Clock (MHz)
1085 Boost Clock (MHz)
7.0 Gbps Memory Speed
230 W Graphics Card Power

GTX 780
2304 CUDA Cores
863 Base Clock (MHz)
900 Boost Clock (MHz)
6.0 Gbps Memory Speed
250 W Graphics Card Power

GTX TITAN
2688 CUDA Cores
837 Base Clock (MHz)
876 Boost Clock (MHz)
6.0 Gbps Memory Clock
250 W Graphics Card Power


From my experiences (GTX 2xx), if CUDA then not the whole graphic card is used, so the max power consumption won't used - ~ 3/4 instead.
This is still true with the above graphic cards?

Every help will be welcome and appreciated.

Maybe this will help members to decide which graphic card they could buy, depend of prize, RAC, wattage (electricity bill ;-).

Thanks.

According to GPU-z my GTX 660's running 3 concurrent workunits run at around an average of 80-85% TDP.

Cheers.

Are they running at their base or boost frequency?

Boost.

BTW boost clock is 1100MHz on these Gainwards.

Are you running a Competion? If so what do we have to do to win the Prize? unless you ment Price? ;-)

More & more tempted to buy a couple. Shame i don't have the funds.

Somthing that could add to the table is a SETI performance of each GPU, minutes/seconds to crunch a reference WU for example, similar like the Fred´s performance program makes with the number of WU but instead of number of WU test real crunch time (performance in SETI), that could be very usefull to guide those who want to buy a new one.

I saw at some internet shops, the GTX680 and GTX770 for around the same price.

Which would be the better choice (highest RAC and/or best RAC/wattage)?

(BTW, the GTX7xx series will get a SAHv7 cuda55 app? ;-)


GTX 680
1536 CUDA Cores
1006 Base Clock (MHz)
1058 Boost Clock (MHz)

vs.

GTX 770
1536 CUDA Cores
1046 Base Clock (MHz)
1085 Boost Clock (MHz)
7.0 Gbps Memory Speed
230 W Maximum Graphics Card Power


Thanks.

Here the specs are very telling. This is a tweaked/improved GTX 680. They made the memory controller better. The higher max power figure is because you have a better cooler and 'GPU Boost 2'. This means you can OC the card more if you want, with boost 2 allowing voltage unlock as well as higher power target. Clock for clock at reference voltage it will use the same or less power, and be cooler... it is just possible to push this card higher than reference 680,without modifying the hardware.
BTW, the GTX7xx series will get a SAHv7 cuda55 app? ;-)
Of course, but this will make most difference in 780 in TITAN after I manage to get a 780, as these have some special instructions that do *exactly* the same things as some of my optimised code, with single hardware instructions, without memory transfer costs.

I'm sure he meant price. You can forgive a German for not always spelling English correctly, right? On the other hand, what's a competion? ;)

After 'Kepler' (6xx/7xx series) comes some day next year 'Maxwell' the first GPU with ARM CPU.

How much would this 'Maxwell' (and/or ARM CPU) increase CUDA and OpenCL calculation speed?

GTX880 douple (CUDA/OpenCL) performance as GTX780?

The apps calculation will change and will then not use the system CPU, but rather the ARM CPU?

Thanks.

Because ..
GTX 760: 1152 CUDA Cores
GTX 780: 2304 CUDA Cores

Does this mean the GTX780 (could) have ~ double SAH-RAC as GTX760?

Not quite...

Note that GTX 780 has a slightly lower clock rate than the GTX 760.

Also note that they both have the same memory bandwidth, so you will only get a speedup with the GTX 780 provided the memory speed is not the limiting factor...


Sorry but the only real way to tell is to look up any hosts running those cards, or to run some real-world benchmarks!

Happy fast crunchin',

I'm pretty sure you can't do a direct clock rate comparison. The GTX 780's GK110 GPU generally fares better at compute tasks than the GTX 760/770's GK104 GPU. Different architectures designed for different goals.
