It takes a thousand GPUs to make something serious. Everything else is just kidding

Why GPU? BSGS works on CPU.

btw, what's more important RAM or CPU?

I've tried
AMD Ryzen 9 7950X - 4.5GHZ, 16c/32th + 128GB - 4ek on start, reaches 6ek after week
Intel Core i7-11700K 3.6GHZ, 8c/16th + 128GB - only 2ek, no growth
Intel Core i7-11700K 3.6GHZ, 8c/16th + 64GB - around 1ek, no growth

E5-2670v3 2.3 GHz 12c/24th + 256GB - 7ek on start

Why RAM ?

Storage required for a hash table for a search space of Puzzle 130 to solve with speed like Puzzle 60.....

Each entry in the hash table will contain a key (of 256 bits) and a pointer (of 80 bits) to the corresponding data.
So, each entry requires 256 bits + 80 bits = 336 bits.

Total bits required for hash table = 336 bits per entry * 2^130 entries
Total bits = 336 * 2^130

To convert bits to petabytes:
1 petabyte (PB) = 8 * 10^15 bits

So, total petabytes (PB) = (336 * 2^130) / (8 * 10^15)

Total petabytes (PB) ≈ 42 PB RAM

It is not possible to get such amount of ram in the next 80 years.
