How many TF GhzD/day can the cpu in question provide? A good gpu can do 1000 to 3000, 24/7. (GTX1080, 1650 are ~1000; RTX2080 Super ~3300. The best use of a cpu core for TF is to keep a good gpu well fed, or several.

I'll occasionally run cpu TF, but only for test purposes, or the very rare foray into very high exponents that available gpu software like mfaktx can't handle.
