Difference between Classified 780 & 780TI [Hardware not performance]

Twofour · May 29, 2014

Hello everyone!

Before I start I am not here to find out the performance difference between the 2 cards. I'm here to ask about the difference (if any) of the hardware on the cards!

Basically what I'm trying to figure out is if the 780TI is just an overclocked 780.

I ask because I'm doing a watercooled build and I already have the EK Classy waterblock. I was having trouble finding the 780ti version and the only place that has it listed is Newegg. then my friend got me thinking when he said " why don't you just overclock the 780". Then I was wondering if there is even a difference in hardware between the 2.

Money is not a problem, I just want the best card I can get and be able to overclock it as high as it can go! At the same time I wouldn't mind saving the 300$~ and putting it somewhere else.

Thanks guys for taking the time to read! hopefully one of you can help me!

the 780 has 2304 cuda cores while the Ti has 2880. The vram is also 7Ghz on the ti vs 6Ghz on the 780, but I don't think the hardware is different in that case, just the Ti is clocked higher.

The 780Ti is a stock OC'd card you can overclock the 780 to match the 780Ti stock speeds but if you OC the 780Ti it will preform significantly better than the 780 OC. To sum it up the 780Ti is a better card and is a very good card.

That is not completely true the GTX 780 Ti has 25% more CUDA cores than the GTX 780... So with both cards clocked the same the GTX 780 Ti will be about 15-25% faster.

Thanks for the quick answer ! Question -

If I were to overclock the 780 would the cuda core go up? or is that stuck at that value. I understand that I can take the 6ghz up to 7ghz but what I'm wondering is will both cards max out at the same numbers? or would the 780TI overclock higher than the 780.

Twofour :

CUDA cores are physical, overclocking will not increase them... They both overclock well, but say you get teh GTX 780 to 1200Mhz and the GTX 780 Ti to 1200Mhz... the Ti will still produce 15-25% higher frame rates.

Twofour :

No, the Cuda cores function as individual cores. Adding the Cuda core count is as impossible as making a 4-core CPU to a 6-core one.

Wow guys thanks for all the quick responses! I think I get the Idea now

From what I'm seeing here is that even at same clock speed the 780Ti still has the edge over the 780.

Thank you very much everyone! upvotes for you all!
