The new 450 integrates one to eight cores, 8 KB to 512 KB L2 cache and supports 4x multi-sampling with "virtually no performance drop" as well as 16x anti-aliasing that is "outperforming all implementations of comparable quality", ARM states. A reference quad-core Mali-450 MP GPU with 256 Kb L2 cache has a size of 8.6 mm2 and is clocked at 240 MHz or 480 MHz.
ARM says the 450 will hit 104 million triangles per second and up to 3.8 gigapixels per second at 480 MHz. There was no information how much power the GPU consumes. In comparison, the 400 MP tops out at 44 million triangles per second and 1.1 gigapixels per second at 400 MHz.
The new 450 chip is targeted at the lower-end range of tablets and TVs, but can run 2K and 4K screen resolutions. ARM said that the new GPU design is available now.
To be honest with youm i dont think that the SoC in phones is what determinates the battery life, i say its the screen, put the brightness in 0% and you get 8-9 hours of battery life but if you put it in 100% you barely get 5.5-6 hours
Sorry, had to say it once :D
