GeForce GTX 780 Details

NVIDIA GeForce GTX 780 Specification

• GPU: GK2xx
• Base Clock: 1100 MHz
• Boost Clock: 1150 MHz
• Memory Clock: 1625 MHz (6500 MHz effective)
• Memory type: 3GB GDDR5
• Memory Interface: 384-bit

According to Chip.de, the GeForce GTX 780, which would supposedly use this processor, may feature 2304 CUDA cores. The site also reveals that the card would use 3GB GDDR5 memory across a 384-bit interface. Nevertheless, our sources are less enthusiastic about this card. From what we know, it would have 1920 CUDA cores (2110 tops), 160 TMUs and 48 ROPs. Needless to say, probably the most certain information right now is the 384-bit interface. The site also mentions the exact clock speeds, but it seems that these are pure speculation, since NVIDIA does not usually launch their cards with such round clock numbers. Anyway, from what has been said so far, the GPU would be clocked at 1100/1150 MHz (for base and boost respectively), and the effective memory clock is 6500 MHz.
These specs suggest that the memory bandwidth would increase from 192 GB/s to 312 GB/s (that’s 62% increase). The texture fill-rate would be around 170.6 GT/s (32% increase) and pixel fill-rate 52.8 GP/s (64% increase)

The Kepler Refresh Naming

It’s still uncertain whether NVIDIA will launch their new GPUs with the GK1xx or GK2xx naming. However our sources and the leak from previous week suggest that the Kepler Refresh is using a GK2xx scheme. What that means is there is no GK110 or GK114 powered GeForce graphics card coming.

GeForce GTX 780 Launch Date

The GTX 780 is currently planned for February/March 2013. First  samples should be available in January. The release date of GTX 780 might be changed depending of the sales of current Kepler cards.videocardz.com
