EVGA "GeForce Meets PhysX" Mockup: GT200b and 896MB on the left, G92b and 512MB on the right
As you can see in the crude mockup picture we created above [created with two images from colleagues at TechPowerUp!, image doesn't feature correct amount of memory chips], EVGA took the single PCB design from GeForce GTX 295, left one GeForce GTX 275 and simply placed a G92 GPU next to it. From one side, you have 896MB used by the GTX 275, and the second GPU - G92 uses only 512MB, making up for a never-seen-before 1408MB of GDDR3 video memory.
