The american webshop NewEgg had the specs of a GeForce GTX 650 Ti from the Galaxy GTX 650 Ti GC for a little while. It seems that the product comes with 768 shader processors opposed to what was reported earlier. That would give the card a significant enough boost in performance to close in on the Radeon HD 7850.
Galaxy GeForce GTX 650 Ti GC 1GB (65IGH8DL7AXX) looks identical to GTX 650 GC. The listing said that the card would have 768 CUDA cores and feature 966 MHz GPU clock. Only the memory type and interface is the same as previous rumors suggested. The card has 1GB of GDDR5 memory operating on 128-bit interface.
Galaxy GeForce GTX 650 Ti GC
Core Clock: 966MHz
CUDA Cores: 768
Effective Memory Clock: 5400MHz
Memory Size: 1GB
Memory Interface: 128-bit
Memory Type: GDDR5
It looks like the card would require only one 6-pin power connector and would not support SLI technology. I’m not sure why did the listing say about different number of CUDA cores, but it’s highly unlikely that there are two versions with different cores count. So this might be only a mistake, or previous rumors were wrong.
This model was listed for $149, however it’s a non-reference model so the price might be little higher than MSRP of reference model.
