WOW!... Someone is upset. They never did anything similar? Oh, this is going to be a waste of my time.
Even the article mentions GT 730. Have you even used your brain to ask yourself what happened with GT 730? Nope? Knew that. Let me explain to you the GT 730 fiasco in a few words. Under the GT 730 brand you will find. Models with 64bit DDR3 memory and bandwidth even lower than 10GBs/sec and GDDR5 versions with bandwidth at 40GBs/sec. And believe me, it is worst than the GT 1030 case. Because, while you will find cards that are using a Kepler core, you will also find models using a Fermi core. Yeap, you read it correctly. One product name, different generations and also different support for DX12.
I also see you have problems understanding what you read. The conclusion is not irritating because the author is critical. It is irritating because the author reacts like this is the first time Nvidia did that. And the most irritating part is that GT 730 is mentioned in the article, but only as a comparison for the memory bandwidth, not as an example of Nvidia doing the same trick again.
As for that link. Google GT 730, go to Nvidia's official page, check the specs. Ask yourself how the hell three totally differect cards share the same model number. BusinessWorks?
PS Bonus.
Nvidia always posts memory bandwidth numbers of DDR3 models with memory speed at 1800MBs/sec.But they let their partners to freely choose whatever memory they want. So most low end models in the market came with memory from 1066MHz to 1600MHz. Cute, isn't it?
