Two AMD Radeon Navi graphics cards have made a sudden appearance on 3DMark and AOTS benchmarks. The Navi based GPU variants were found by TUM_APISAK and it looks like we also have some early specifications for what look to be engineering samples running in test labs.

The two AMD Navi GPU variants are not the same since they have a different device id. The variant which has the specifications featured on 3DMark is the ‘731F: C1’ and it comes with a clock speed of 1000 MHz and 8 GB of memory that is clocked in at 1250 MHz. Now what is interesting about this memory clock is that if we speculate that it’s GDDR5 based, then that would translate to 5 GHz which is quite low for a 256-bit variant that this card seems to be.
