HKEPC found out from Taiwanese manufacturers that the GeForce 8600 GTS, GeForce 8600 GT and GeForce 8500 GT will all three be launched in April. But none of these cards will have HDMI support.
Based on G84, the whole GeForce 8600 family is all fabricated by TSMC with 80nm technology. The top model, GeForce 8600GTS, codenamed G84-400, has a core speed at 675MHz, and features 2GHz DDR 128Bit 256MB graphic memory. GeForce 8600GTS is therefore expected to give more power than GeForce 7900GT.
The second top, GeForce 8600GT, codenamed G84-300, would be a weaker version of GTS, where its core speed is lowered to 420MHz or below, and features 1.4GHz DDR graphic memory only. GeForce 8600GT is expected to give more power than GeForce 7600GT.
On the mean while, NVIDIA also plans to release new value G86 product, GeForce 8500GT, codenamed G86-300. Based on G84, its architecture is much simpler, and it will be fabricated by 80nm technology as well. GeForce 8500GT is expected to give more power than GeForce 7600GS.
All G84 and G86 except G84-P400 would have no HDCP and native HDMI support on this release. Yet, since its rival AMD makes these features in all of its upcoming RV630 and RV610, source cited NVIDIA's promise that the company would put in these features in later time.
