K1 is impressive in AnTuTu benchmark

During CES 2014, NVIDIA was showing off a new processor that fits into the Tegra line: the Tegra K1. This week, some benchmarks that are claimed to be from that chip have hit the web.
 
We already know most of the hardware specs on the K1, including the fact that the chip has 192 CUDA cores. The chip is a 32-bit quad-core unit with another version tipped that will have dual Denver 64-bit cores operating at up to 2.5GHz.
 
The K1 has a maximum clock speed of 2.3GHz (in quad-core configuration) and supports DDR3L and LPDDR3 memory up to 8GB. The chip will also support displays with resolution up to 3840 x 2160.
 
Benchmarks for the chip show what it was able to score on the AnTuTu running Android 4.4.2. The unknown device that was used to run the benchmark has a screen with 1920x1080 resolution and 2GB of RAM.
 
You can see the full results of the benchmarks in the images below:

The Tegra K1 should make for some impressive smartphones and tablets when they start coming to market; but NVIDIA first has to get on the ball with design wins.

While I generally agree with you, there are some odd exceptions when it comes to mobile devices. On a PC almost every individual part has their own processor, while on a phone a lot of peripheral processing is done on the CPU. Phones also tend to be doing more and more video and photo work which is much easier (and efficient on the battery) to run multi-core than games and software. Also, background programs and processes can take quite a few CPU cycles, and a duel core game will run much faster if it can offload those processes to another core.

So while a quad core may well be overkill, there are plenty of reasons to have more than 2 cores. It would be really interesting to see a design with one small core to manage the phone peripherals and background processes, and then 2 normal sized cores to take care of active tasks... but I don't think that will be happening any time soon.

Between K1, 805, and the new Atom processors coming down the pipe, it looks like we will see some nice improvements in next gen phones just in time for my contract to expire! Things are lining up beautifully!

The only improvement I'm looking forward to is battery life (hence my bias towards dual-core solutions). Unfortunately, with the advent of the smartphone, it has taken a plunge to about one day and it remained around that mark ever since. O know processing power has improved dramatically, buy I'd like to see a decent phone that will last me for a week or so. Not everybody needs the absolute fastest, just like not everybody buys exclusively intel's extreme edition CPUs.

If I may also generally agree with you, if only to add a caveat to your "overkill" statement, each core can in theory run at an independent speed.

Also, power requirements scale higher than speed increase.

So a single core CPU running 1 major task and several smaller tasks at 2.2ghz will use significantly more power than a quad core CPU with one core at 1ghz and 3 cores each at 400mhz.

When it comes to battery life, spreading as many tasks around as many low speed "processors" as you can is the way to go.

8 or 16 cores simple cores would be even better for 90% of most usage, as far as battery life is concerned.

Frequency vs power is much, much more complicated. I'll try to explain it in brief when I'll get some time on my hands.
