Fritz 17

I would like to know whether it's worth getting Fat Fritz with only a GTX 1660 GPU. I have Ryzen 1700 with 32GB RAM.
Does it just run a little slower or not at at all?

Yes - it will be fine.
Albert says that you can actually use fp16 according to a well-known tester. Not quite as fast as the RTX cards, but 1.7 times faster than plain CUDA.

That particular optimization was introduced in version v0.21.2 (more than 4 months ago).

Thx for speedy response, Graham and Ozymandias. Sorry but I have no idea what fp16 is. Not asking for a lengthy explanation; just a quick pointer for if I buy this thing. Cheers....

Some people are claiming that only one person needs to buy Fat Fritz and then they can distribute its weights so anybody else can use it without buying it. I don't think I've ever seen a precedent for a case like this, it would be piracy to distribute anything on the disk that they sell, except for that weight file?

But is the NN engine all you care about, not the Fritz17 AB engine? If that's the case, it's not worth buying.

Why not?

Well, it depends whether all he cares about is the NN engine.
If that's the case, he should just go with Leela.
But if he's interested in Fritz17, etc., that's different.

I guess it will depend on Fat Fritz results.

When we've looked at analysis of positions on this BB, Fat Fritz has not been any better than a host of NN engines and in one position it's been inferior.
