Base Clock VS Boost Clock

[Th3-Trinity]

I just got rid of my 980 Boosted to 1241 MHz. In return, I bought the 980 Ti that was 1190 MHz. Is it really going to make much of a difference if I manually clock the new one to 1250 to match the old card's speed? Or is this going to cause some major issue? My understanding was that the old card was just OC'd in the factory higher than the new one. So I can just OC it myself correct? It really only is a small jump from where it is now.

Only one way to find out mate, do it.

However, the 980ti at stock should be a lot faster than the 980.

I had the GTX 980 Matrix D:

As long as you don't get a bad card, as in bad silicon lottery, you should be able boost your base above whatever the factory overclocks are at. It will depend on your individual cards ability, as far as how high you can overclock.

What brand card did you end up getting? The 980 boosts really well and so does the 980 ti, but even if you weren't able to boost, the 980 ti reference stock clock speeds at 1000 is still faster than a heavily overclocked 980.

My old 980 matrix came at a clock of 1250. The new one (Ti) by evga is at 1190. I just wanted to catch up to the old one. Also, more Cuda cores so maybe that is it

A lot of people hit 1250 base clocks with that evga card, but will still depend on your individual card. But even if you weren't able too, the 1190 overclocked evga card will still be quite a bit faster than your 980.

Why would it be faster? Is it because it offers more cores?

It's more than just that but yes it has more cuda cores at 2800 ish vs 200o ish for the 980. The Titanx has 3000 ish. Streaming multiprocessors is 22 vs 16 for the 980 and 24 for the titanx. ROPS are 96, same as titanx and 980 has 64. 176 texture units vs 128 for the 980 and 192 for the titanx. The die size is the same as titanx at 601 mm² vs 398mm2 for the 980 so, transistors are 8 billion, same as titanx while 980 has 5 billion.
