M2 Ultra consists of 134 billion transistors &mdash; 20 billion more than M1 Ultra. Its unified memory architecture supports up to a breakthrough 192GB of memory capacity, which is 50 percent more than M1 Ultra, and features 800GB\/s of memory bandwidth &mdash; twice that of M2 Max. M2 Ultra features a more powerful CPU that&rsquo;s 20 percent faster than M1 Ultra, a larger GPU that&rsquo;s up to 30 percent faster, and a Neural Engine that&rsquo;s up to 40 percent faster. It also features a media engine with twice the capabilities of M2 Max for blazing ProRes acceleration.<\/p>\n<\/blockquote>\n\n<p>Previously:<\/p>\n<ul>\n<li><a href=\"https:\/\/mjtsai.com\/blog\/2023\/06\/05\/mac-pro-2023\/\">Mac Pro 2023<\/a><\/li>\n<li><a href=\"https:\/\/mjtsai.com\/blog\/2023\/06\/05\/mac-studio-2023\/\">Mac Studio 2023<\/a><\/li>\n<li><a href=\"https:\/\/mjtsai.com\/blog\/2023\/01\/17\/apple-m2-pro-and-m2-max\/\">Apple M2 Pro and M2 Max<\/a><\/li>\n<li><a href=\"https:\/\/mjtsai.com\/blog\/2022\/03\/08\/apple-m1-ultra\/\">Apple M1 Ultra<\/a><\/li>\n<\/ul>\n\n<p id=\"apple-m2-ultra-update-2023-06-13\">Update (2023-06-13): <a href=\"https:\/\/wccftech.com\/apple-m2-ultra-soc-isnt-faster-than-amd-intel-last-year-desktop-cpus-50-slower-than-nvidia-rtx-4080\/\">Hassan Mujtaba<\/a> (via <a href=\"https:\/\/news.ycombinator.com\/item?id=36271804\">Hacker News<\/a>):<\/p>\n<blockquote cite=\"https:\/\/wccftech.com\/apple-m2-ultra-soc-isnt-faster-than-amd-intel-last-year-desktop-cpus-50-slower-than-nvidia-rtx-4080\/\"><p>The CPU managed to post a single-core score of up to 2809 points in single-core and 21,531 points in the multi-core tests.
