It's hard to make direct comparisons solely based on specs, in part because Nvidia is inconsistent about the specs it provides at launch. You usually have to wait a little bit until people dig in and ferret them out. 

Most of the specs Nvidia's provided for the $6,300 Quadro RTX 6000 and the $2,500 Titan RTX are almost identical -- the Quadro does have a faster base GPU clock speed and four DisplayPort connectors vs. the Titan's three. So I can't wait to find out what magic the Quadro performs that merits an almost $4,000 premium. Given that neither GPu is shipping yet (the Quadro's in preorder and the Titan is slated for the end of November), we'll have to wait and see.
