Is Nvidia cheating?

Hello,

I was browsing the new NVIDIA gpus while checking the old ones, and found gtx 970 has 6Gbps "memory speed" on the 1070 comparison page ( http://www.geforce.com/hardware/10series/geforce-gtx-1070 ) , meanwhile gtx 970 has 7Gbps "memory speed" in its dedicated specs page ( http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-970/specifications ) (screenshots for obvious reasons) http://prnt.sc/bmmq9f http://prnt.sc/bmmqbr
