LEADTEK has released several video cards from its WINFAST A400 GT Series, based on nVIDIA's 6800GT chip with low memory speed. The reasons for this are still unclear. What is more, the company did not publish any information about this move, and you can see the new card data only in some sites that sell the company's products.
The change is to reduce the memory speed from 1000MHZ to 900MHZ, which will make the card slower than other 6800GT-based cards produced by other companies.
It should be noted that the author of the article did not receive a response from LEADTEK until the publication of the report, but evidence of the existence of such a card in the market can be found At the GameVE.com store, In which the reduced data are published.
