Cross-platform computing power
Mathematica is optimized for the latest operating systems and hardware, so you can use any system you want. Hardware Specifications
Processor: Intel Pentium IV 2.4 gHz or equivalent Disk Space: 5.5 GB System Memory (RAM): 2 GB+ recommended Internet Access: Required in order to use free-form linguistic input and computable data functionality. To use Mathematica‘s built-in GPU computing capabilities, you’ll need a dual-precision graphics card that supports OpenCL or CUDA, such as many cards from NVIDIA, AMD, and others.

Linux

Ubuntu 7-12 RHEL 5, 6 CentOS 5, 6 Debian 5, 6 openSUSE 11, 12 Fedora 9-17 Mathematica 11.3 has been fully tested on the Linux distributions listed above. On new Linux distributions, additional compatibility libraries may need to be installed. It is likely that Mathematica will run successfully on other distributions based on the Linux kernel 2.6 or later. Mathematica supports an X Window System front end, and since Version 7 has used the Qt application framework for its user interface—the same used by the major Linux desktop environment KDE. Regular tests are run on both enterprise and popular open-source Linux distributions
