Default Nvidia GTX 745 4GB ???

I'm surprised to see that there are no stats on mersenne.ca about this GPU.
Anyone know anything about it in regard to mfaktc performance?

Can this statement be true? "GFLOPS and GHzday/day is in linear equation/relation, (so 2 times the GFLOPS, about 2 times the GHzday/day), for the same model gpu normal and M."
Tried out for 460-460M & 970-970M from mersenne.ca table, worked, can be coincidence.

745 793.3 GFLOP (gpuboss geforce.) 55 W 4 GB
745m 642.8 GFLOP (gpuboss, mersenne.ca) 45 W 2GB
745a 642.8 GFLOP (techpowerup mersenne.ca) 33 W 2GB
same memory speed (eff: 1800), type (ddr3/gddr5), bus (128 bit), frequency, bandwidth 28,8Gbps , clockspeed (837)-or base clcok 1033??

similar core count possible: https://en.wikipedia.org/wiki/GeForce_700_series

It should give you 3/4th of a GTX 750's performance. It has terrible memory bandwidth though, so I wouldn't buy it for gaming.

It has ddr3 RAM. Terrible bandwidth.

The standard already for quite a while is GDDR5.

Those huge display resolutions mentionned for it are @ 24 hertz refreshrate. I guess within half an hour you can see the doctor then.
