With Tegra 3 “Kal-El” closer, Nvidia is revealing details of his successor Tegra 4, known by the code name “Wayne“, which true to its name code will be available in 2 versions: we call it unofficially “Robin”, for mobile devices, and version is “Batman” with more powerful focus for netbooks and notebooks.
A few days ago we confirmed that Nvidia Tegra 4 would be available in the course of 2012 and apparently that SoC (System On a Chip) will be based on ARM Cortex microprocessor A15 and come in two versions aimed at different markets: one of lower power with 4 cores and IGP with 24 CUDA Cores (shaders), and a larger power with 8 cores and between 32 to 64 shaders. The lower power version will be focused on smartphones and other portable devices, while the more powerful version will be focused on netbooks and low-power notebooks with screens up to 13 “will work with the upcoming Windows operating system 8 for ARM.
The IGP Tegra 4 lower power (24 shaders) will probably use one based on the GT200 core (8 cores per SM and SMs per TPC 3, ie 24 shaders), while the higher power version with 32 to 64 shaders speculated that the IGP could be based on Fermi, because as we know Nvidia has 2 variants of its GPUs Fermi one with 32 cores per Streaming Multiprocessor (SM) that is used in the high GF100/GF110, and another variant SM 48 cores used in the Fermi mid to low, both organized in groups called GPCs formed each by 4, 2 or 1 MS, depending on the range, presumably a variant with a CPG consisting of 2 cores with 32 SMs each, where the version with 32 CUDA cores could have 1 SM disabled, while the version with 64 cores would both SM’s enabled. Well so far everything is in speculation.
Nvidia promises that the most powerful graphics performance “Wayne” will have a 10 times higher than the current Tegra 2, and 2 times the performance of Tegra 3 “Kal-El“, in addition to support PhysX technology, OpenGL 4.1 and 1.x OpenCL .
