Models built with the new GF104 architecture are expected to have less horsepower but with features on par with their higher-end counterparts. Rumored specs include 256 shader cores, 64 TMUs, 32 ROPs, and a 256-bit memory bus. The graphics core is said to be destined for use in three cards, but no other details are available.
The GTS 450 should be a touch faster than the HD 5830, but its price will probably reflect that edge, and it's expected to cost between €200 and €230. The GTS 400 will supposedly outperform the HD 5770, and cost around €160 to €180. Meanwhile, GTS 430 will carry 192 shader cores, 48 TMUs, 24 ROPs, and a 192-bit memory bus, should match the HD 5770, and will run between €130 and €150.
Other cards based on GF106 and GF108 cores should follow, with the former selling for €60 to €100, depending on the SKU, and the latter for €30 to €40.
