As you already know, AMD's Tonga XT GPU has been quite elusive and although it should have appeared as a desktop graphics card, this never happened but luckily we now have some of the first benchmark results from that same GPU since it is exactly the GPU that Radeon R9 M295X is based on, which is also a key part of Apple's new iMac 5K.


While we do not have full set of benchmarks but rather just Cinebench results, it appears that Amethyst XT GPU, as AMD decided to rename it since the R9 M295X is a mobile graphics card, is still based on AMD's 28nm Tonga GPU architecture, packs 2048 Stream Processors, works at 800MHz GPU clock and packs 4GB of GDDR5 memory clocked at 1375MHz and paired up with a 256-bit memory interface.

Judging from these first benchmarks provided by Danny Winget over at Youtube and caught by Wccftech.com, the Radeon R9 M295X is actually faster than both the GTX 780M and the GTX 770, at least in Cinebench R15. While there are no results for a bit more powerful Nvidia GTX 980M or the rest of the Nvidia Maxwell mobile GPU lineup, it is clear that AMD has a decent mobile GPU with Amethyst XT.

Hopefully, we will hear more about the Tonga XT/Amethyst XT GPU as well as see that same GPU in a desktop graphics card.
