Perhaps not many people knew about it, but the CPU, or the brain that handles all in a personal computer, has been revised from time integrating characteristics of video cards and AMD in particular has made her a model called APU.
One designed for PlayStation 4 is the most powerful ever made, and there is another one on the market!
To declare is John Taylor, global business manager of AMD, during an interview with the Inquirer magazine, stating that “no one has reached that level of number of cores, number of teraflops.” This model inherited from the APU Series A Model “Jaguar” was customized by Sony engineers according to their policies.
The solution inside the console from Sony is made up of eight core 64-bit x86 architecture-based “Jaguar”, that we begin to know last summer, and a GPU AMD Radeon family, certainly based on Graphics Core Next architecture but at the moment it is not clear if the first embodiment, the second (still waiting) or a strange hybrid all to know.
“The GPU has a unified set of 18 computer units (probably 1152 stream processors), which generate 1.84 Teraflops of power that can be freely applied to graphics operations simulation or a mixture of the two,” said the Nissan during the presentation. Recall that there are also 8 GB of GDDR5 memory, available CPU and GPU via a 256-bit channel, for a bandwidth of 176 GB / s. There are also “hardware blocks” specialized.
It is a solution “semi-custom” also incorporates the proprietary Sony for now unknown nature, which is obviously not present in AMD solutions that come on the market. Also we will not have the same number of cores and computing capability. This opens up interesting scenarios, because it will help you understand how much customization work did Sony. It is possible, however, that John Taylor has made only one reference to Kabini and Temash, the two APU for tablets and portable low-power that will come in the second half of the year and will be based on its Jaguar.
Recall that Sony Computer Entertainment has revealed only partial information regarding the technical specifications of PS4, including the eight core fact dela APU or CPU and the power of computational performance given in teraflops of more than 1.8. Remains to be seen Microsoft’s answer to the Xbox Infinity.
