The Xenium was great when it first came out, but now Xodus is getting lazy. The matrix and chamelion chips were fucking amazing in their times, some of the best chips. (Hell, in my primary box i still use my Chamelion LE) Now, Xodus is at the bottom of the food-chain. They are relying on gimmicks to increase sales. The gold has no advantage what-so-ever except to look pretty. Gold does has an advantage in electronics as it's a better conductor, but as the old saying goes "A chain is only as strong as it's weakest link" and i'm guessing it's using a standard lead based solder, so it will be like every other chip. Also, size wise, that's easy. Just shorten the traces and scrunch it all together. Nothing but gimmicks to raise sales.
