The bandwidth is far more than any other tablet PC I have ever seen.  It is almost as fast as the X1's bandwidth (64 GB/s).

But it's compute capabilities will put it at near have the X1, if not a little more.

A9X is some 2x A8X when it comes to GPU, which puts it at somewhat under 500 GFLOPS FP32 - which is still way off XOne's 1.3 TFLOPS...unless you were referring to nVidia Tegra X1, which is rated at 512 GFLOPS.

Do you mean the Nvidia Tegra X1 and the Shield Console? That may be above the Wii U (possibly though Nvidia sometimes overstates performance), but technically it's not been put into a portable form factor yet, though Nvidia filed a trademark for a tablet that's upcoming with the X1 chip. 

Lol, yeah. I was thinking Shield, but I typed "Steam."

I didn't realize they hadn't released a tablet with that SOC yet. I recall seeing an Unreal 4 demo that was supposedly running on an X1 powered tablet a while back, so I assumed the tablet would already have released by now.

It sounds like it's coming:

I think they were waiting for 14nm so the chip can run cooler for a tablet form factor and Nvidia just signed that deal with Samsung for 14nm manufacturing. So that's probably why they've waited. The current Tegra X1 is made on the 20nm process whereas A9X is on the 14nm FinFET process. 

I'm guessing they also maybe wanted to see the A9X first too. 

In a word -- yes. 

While Apple devices are very costly at retail, the biggest cost of them by far is the high resolution touch LCD displays. 

The Apple A8X was estimated to cost only $22 as of last year, so the new A9X might be a little more than that, but probably not much more, Apple likes to maintain the same profit margin on their devices. 

$50 - 6-inch 1280x720 cheap but decent LCD display

$40 processor - Lets say Nintendo goes for something beastly

$35 - 4GB LPDDR4 RAM

$4 - cameras (Nintendo cheaps out)

$20 - Sensors + NFC chip

$5 - WiFi Chip

$14 - Battery (large 32 wH battery)

$10 - NAND Flash (16GB or 32GB)

$20 - Misc

$5 - Manufacturing cost

Yeah ... I could see it for under $250 honestly if Nintendo is wlling to sell it at cost. Keep in mind the Nvidia Tegra X1 console is $199.99 and that's a similar class of processor, but obviously it has no LCD screen + battery, but Nvidia is likely pocketing a fat profit margin there too. 

Here's the cost break down for the iPad Air 2, but keep in mind the Air 2 has a massive 10 inch screen at a huge 2048x1536 resolution and is made of fairly premium materials (also ignore the cellular models):

Remember the Sony Vita basically used the same processor as the iPad 3, but the Vita was able to launch at $250, while the iPad 3 was $500-$800.
