Roadmap detailing Nvidia’s Upcoming Kepler based Geforce GPU’s has been leaked. The roadmap reveals details on specs and release dates of the Kepler based 28nm chips.
- Gk110 : Dual Chip GK104 × 2, supports PCI Express Gen.3
- Gk104 : Performance GPU, supports PCI Express Gen.3
- Gk106 : Mainstream GPU, supports PCI Express Gen.3
- Gk107 : Entry GPU , supports PCI Express Gen.2
According to the roadmap, Nvidia would firstly release the Lower-End lineup followed by the Mid End and later on Higher End GPU’s, This would ensure that the company doesn’t conflict with any TSMC’s 28nm manufacturing issues.
The first 28nm GPU codenamed GK107 would launch in 1H 2012, GK107 would replace the lower end Geforce 500 Series cards which include GT 520. The card would feature a 28nm TSMC design, 128-bit GDDR5 memory and support for DX11.1 and PCI-e Gen 2.
The launch of the Mainstream lineup is expected a month or two late after the lower end cards are released. Codenamed GK106 these would replace the GTX 550Ti GPU, Featuring 256-bit GDDR5 Memory and support for DX11.1 and PCI-e Gen 3.
Next up would be the GK104 chip which would include Nvidia Performance Segment cards replacing the current gen GTX 560Ti/GTX 570 GPU. The GK104 would feature a 384-bit GDDR5 memory interface. Launch of these cards would be expected in 2H 2012. Some performance estimates reveal that these card would be able to outperform AMD’s current High End HD6900 Series GPU’s.
Nvidia’s Dual Chip Flagship GPU codenamed GK-110 would also feature two of these GK104 chips. The card would be released in 2H 2012 and would feature a 28nm design, 384-bit x2 GDDR5 Memory and support for DX 11.1 and Gen 3 PCI-e interface.
Finally, In 1H 2013 we would see the launch of Nvidia’s fastest Single Chip GPU codenamed GK112. This would be a monstrosity which would replace the GTX 580 and feature a 512 Bit wide memory interface and Gen 3 PCI-e/ DX11.1 support. One reason Nvidia opted for using GK104 in its dual chip GPU instead of GK112 could be the higher power consumption and heat dissipation even after being built on a 28Nm design however details are yet unknown.
