We have told you earlier that Nvidia is preparing 55nm GPUs against current ATi's offerings like RV670, RV635, RV620 as well as RV770. VR-Zone has managed to find out Nvidia is planning a GeForce 9800M GTS refresh codenamed NB9E-GT1 and a new GeForce 9800M GT codenamed NB9E-GS1 based on 55nm G94b architecture. Both GeForce 9800M GTS and 9800M GT have 1GB of GDDR3 memories onboard. Interestingly, the GeForce 9650M GT codenamed NB9P-GT is actually a 55nm G96b.
