Reviews show 1900 is slower than 1750, is this true and why?

Hi, I am looking into buying a Buffalo router and wanted to go with the WXR-1900DHP.

I have a gigabit fiber connection at home and I am interested in getting the most out of it, so WAN to LAN throughput matters to me. I know of only one site that measures this comprehensively and it's here:

http://www.smallnetbuilder.com/tools/charts/router/

They show the 1900 to be about 150Mbits slower than the older 1750. So my questions are:

1) Is this true?
2) If so, how could it be if the 1750 has an 800MHz chip and the 1900 has a 1GHz chip?
3) Was it just a firmware issue that has since been solved?

My apologies if this has already been covered, but I was unable to find any info on it.

Thanks.

I have seen some reviews saying this but i have not tested it. Although the 1750 has a 800mhz CPU, it is capable of being overclocked to 1600mhz on DDWRT firmware. As i said, i have no information on the 1900ac as the reviews and suggestions and research made me think the 1750 is quiet good enough for me.

Thanks. I would like to get some feedback from official support staff to determine whether the newer router is indeed slower than the older one.
