Information on Nvidia’s next generation Tegra 4 chipset has been leaked on VR-Zone. The new chipset will apparently run between 1.2ghz and 2.0ghz and it will use the same 4-PLUS-1 configuration as Tegra 3, but with less ARM A15 cores.
There is going to be three A15 versions, according to the specifications sheet. The T40 is going to target 10 inch tablets and run at 1.8ghz and the T43 is clocked a little higher, at 2.0ghz. The AP40 will cost less and run between 1.2ghz and 1.8ghz.
The Sp3X uses the older A9 cores but will pair the 1.2ghz to 2.0ghz chipset with an LTE and HSPA+ modem. It will be released later with the T40 expected to hit in Q1 2013. The other three versions are said to launch in Q3.
This move to four A15 cores could mean that Nvidia have optimised the heat output, which was one of the problems they faced with the Tegra 3 platform from using A15 cores.
Kitguru says: We would imagine that Tegra 4 will really be well suited when paired up with a higher demand Windows 8 based tablet which are due for released later this year.
