Transistor count of modern FPGA
« on: April 20, 2018, 05:21:43 pm »
Roughly how many transistors are there in a logic cell of a modern Xilinx FPGA like an Artix 7?
Cryptocurrency has taught me to love math and at the same time be baffled by it.

Cryptocurrency lesson 0: Altcoins and Bitcoin are not the same thing.

The Virtex 7 2000T has 6.8 billion transistors.
A mid size Artix will be a about 100 million.

Yes, the Virtex-7 2000T is said to have 6.8 billion transistors for 2 million logic cells, which would equate to 3400 transistors per logic cell.
Since the Artix-7 is based on the same architecture, it's probably in the same ballpark.

Or go with Intel, who are shooting for the stars with their new 30 billion transistor (!) Stratix 10.  ;D

Note that a LOT of those transistors are not in the LUTs and FFs but in the routing fabric, there are a lot of fixed at bitstream load time multiplexers involved in routing, and things like the DSP and BRAM cores are not exactly cheap transistor wise either (But much cheaper then building the same things out of generic LUTS and FFs!).

Only a fairly small percentage of the silicon goes on LUTs and user flipflops, most of it is routing and whatever special purpose blocks are appropriate.
