Report: GTX 770 Spotted Again, Specifications Confirmed

Because a number of people were doubtful about the validity of the previous images of the GTX 770, Chiphell has released yet another image. In the meantime, there's also been more talk of the specifications.

The graphics card will apparently pack the GK104 GPU with eight of the SMX units enabled. This would give the card a total of 1536 enabled CUDA cores, 128 TMUs, and 32 ROPs. The base clock would be 950 MHz, with the boost clock set at 980 MHz. The card would also have only 2 GB of GDDR5 memory, which would run at an effective speed of 6.00 GHz over a 256-bit memory bus, letting it pump out 192 GB/s of bandwidth. This makes the GPU and memory parts of the card almost identical to the GTX 680.

What appears to be different is the PCB design. Apparently, the card has a lot more overclocking headroom due to a standard TDP of 250 W (vs. the 195 W of the GTX 680). The default voltage would also be above 1.3 V. The card would be fueled by a 6-pin and 8-pin PCIe power connector setup. The PCB is reportedly much more similar to the design of the GTX Titan rather than the GTX 680, although this particular sample could be an engineering sample.

It also appears that the card will launch on May 30, 2013.
