nForce 415D/420D chipset differances?

What is the differance between the nforce 415d and 420d chipsets?

EDIT: Who would have guessed that someone had just posted the same question? My bad, lol...

No on-board video on the 415D, only sound. 🙂

Cool, thanks- but doesn't the 415 have a VGA port bracket that plugs into a header somewhere on the mobo? That looked like one of the accessories on one of the NewEgg picture details.

Nope, there shouldn't be. 415D only has Twinbank, sound and LAN. 😀

Plus the 5.1 add-on card and the USB bracket, which is about the only add-on's I've seen with nForce. 🙂

Ah ok. Did MSI ditch Twinbank (is that an MSI or nVidia technology?) on the 420? Was it just lame or something? What's the story?

What is twinbank?

 

[StattlichPassat]

It has something to do with using two sticks of RAM instead of one to achieve 128bit performance, over the otherwise one stick 64bit performance. I'm still not totally certain what that really does for me though.

Does twinbank have any real world performance increase?

No. The extra bandwidth goes to waste because the CPU is limited by the FSB
bandwidth.

What if you are using the onboard video? Does twinbank matter then?

 

[Damascus]

In that case, without Twinbank, you'd take a huge performance hit. 🙂

Thanks for the info 🙂 I guess I need to go twinbank then 🙂
