How Many Transistors Does This FPGA Have?

The Virtex UltraScale+ VU19P is one big chip.

It has 9 million logic cells and 2,072 user I/Os.

It can be used for emulation and prototyping in areas such as test, measurement, compute, networking, aerospace and defense-related applications.

I used this logic. I know 2 transistors for one NAND gate. But you need two more when spanning control. For a logic gate you need several using combinatoric truth tables. I put that number as ~128. Total…

Accidentally read the press release or did you count them ?

You said what was on my mind: "It is mind boggling!" That's why I posted this. Just incredible

I used this logic. I know 2 transistors for one NAND gate. But you need two more when spanning control. For a logic gate you need several using combinatoric truth tables. I put that number as ~128. Total so far is 4.5 billion. Add 2K i/o would add per logic gate gives 18 billion more. This puts me under 35 billion an way over 2 billion.
I learned approximation back in grade school. And it still works.

Everything about it is mind boggling. Even the CAD system you need to be able to develop with this chip is mind boggling.
I suspect the amount of computing it can do is dictated as much by how much heat you can extract from it as by how fast you can feed data in and out. Of course it can have lots of resident data as well with over 220 Mb of memory built-in.
Comparing apples to oranges with other impressive silicon - a complex 900 sqmm FPGA like this would sit between a CISC monster like a big Core i7 which could have a couple of billion transistors packed in a die a little less than half the size of this chip, and a huge FLASH memory chip like a 512 Gb flash chip that could have 64 layers on a 128 sqmm die.

So most of you hunted down the press release to find the answer. (Not all of you!)

Now, you know something about this chip. What do you think of it as a piece of engineering?
