The current navi 10 core is no more than 40 cu units, with a total of 2560 flow processor units, and even the rumored big navi core is no more than 80 cu units, up to 5120 flow processor units.

The real big core of AMD should be the Arcturus that was leaked before. It was first used in the new generation of radeon insight mi100 accelerator card. It was revealed that the GPU basic frequency is 1091mhz, the acceleration frequency is 1333mhz, with 32GB hbm2 video memory, and the typical power consumption is 200W.

What's more surprising is that the GPU in this big corner is not the rDNA or rdna2 architecture of Navi family, but the Vega architecture beforeDouble the core scale, 128 groups of Cu units in total, divided into 8x16 groups, and 8192 stream processor units in total.

There are signs,AMD doesn't plan to go on the RDNA architecture on the big core GPU, but continues to change the Vega architecture , probably considering that Vega architecture in the accelerator card market is easy to expand and has been optimized for many years, AMD's GPU is not likely to erode NVIDIA's AI and optical market for the time being.

When the core size doubles, the power consumption of the large angle GPU also drops to 200W from the previous 300W, which is mainly to achieve the improvement of energy consumption by reducing the frequency by 1/3, comparing the RX Vega game card is like this, at the lower frequency energy efficiency is OK, the high frequency energy efficiency is completely out of control, in the game card is not worth the loss.
