Details have just recently surfaced behind the near future release of several graphics cards from NVIDIA, designed to fill the void beneath their current flagship 8800 series G80 offerings.
It's been said that these will apparently get launched around the same time as ATI's R600 card (early to mid March).
GeForce 8600 and GeForce 8300 are the two series of graphics cards which will fill the void beneath NVIDIA's already launched 8800 series. Based on the G84 core 8600 Ultra and GT will have 64 and 48 shader processors respectively with cores running at 500MHz and 350MHz. With a 256-bit memory bus and memory speeds at 1400MHz and 1200MHz the cards will replace the 7600 series of today. The launch date for these cards is about the same as for when ATI will launch R600, that is, around CeBIT at the start of March. Except from the 8600 series Bear Eyes has also published specifications for 8300 GT and 8300 GS (via VR-Zone).
