This always happens with CE products

NO RATINGS
Bragging rights, for aspects of the design which may or may not eventually make any sense, has always been the case for products sold to the innocent. I've read that beyond eight cores, memory management becomes so cumbersome that it's hard to get any better performance. Not sure if that's still the case, but it does suggest that migrating to as many as eight makes sense.

What also make sense is to aim for the same amount of processing power in these handhelds as one gets now from PCs. That's when one could conceivably start thinking in terms of docking the handheld to do the real work, and doing away with the separate PC entirely. Looks to like this is where we are heading. The problem is that until now, the battery life of powerful but portable computers has been pretty bad. I wouldn't be surprised in the industry is working hard to fix that problem.

Also, I don't know about 8 cores, but without a doubt 4 cores are a huge improvement over a single or even dual cores, operating at the same clock speed. I've seen that myself, with a single core 2.8 GHz PC vs a qud core 2.8 GHz PC. Like night and day, EVEN THOUGH the applications running on these PCs are not multithreaded.

"True Octa-Core"
junko.yoshida   8/5/2013 2:36:47 PM
When MTK talks about "True Octa-Core," I don't think that's entirely a marketing hype (although it does sound like it).

MTK needs to explain better (or more clearly) the end results (or tangible benefits consumers can experience) of their "true" octa core processing.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
