It should support any, its technically upto 64gb as that was all that was out at the time, the 128gb is sold out atm and only released a few days ago. And seemingly at an offer price of £85 do expect that to double when it comes back in stock. Not guaranteed to work, but it should.
They aren't going to kill it off, it will almost certainly have the NVIDIA k1. All the leaked documentation, shows they aren't killing it off, and that RT and wp will be rolled into one OS for phones and tablets same as ios/android and will use the windows8 store.
Be nice if they had an atom version as well, but that depends when the new one is out as well.
As a student, I can get an Original Surface Pro (64Gb) with a touch cover and pen for £395. I want something to Browse, run Microsoft office and an SPSS like application simultaneously but, it also has to be portable. Is this the best device for me?
Look at 3D Mark figures of the S800 on RT against Tegra 4 on RT, The S800 has a mighty win (~16.9K to ~13.2K, and to me that's a viable benchmark, rather than some obscure ones of no interest)
I'd take an S800 over a Tegra 4 any day of the week.
The verdict of this comparison is that, while pretty much all of the current flagship SoCs are pretty close in terms of CPU power, the Tegra 4 falters slightly when the GPU is put to the test. The Apple A7 does very well on the GPU side, but it's just slightly outperformed by the Adreno 330 GPU on the Snapdragon 800. But really, they're all so close it's hard to pick one as a definite winner. You could call the Snapdragon 800 the overall inner, but I say it's too close to call.
I couldn't argue with a surface pro and touch cover for 395!
he biggest limitation of the Tegra 4's GeForce GPU is that it only supports OpenGL ES 2.0. Right now, this isn't really a problem, as game developers haven't yet migrated to OpenGL ES 3.0 for their games, but that practically destroys the future-proofing of the Tegra 4.
Peak theoretical compute power puts the Tegra 4 behind the A7, but the Tegra 4 is still close enough to the A7 to call it competitive. However, be aware that, while the A7's unified shader architecture allows it to have its peak 115.2 GFLOPS performance available to it in any situation (the same applies to the Adreno 330), the story is quite different with the Tegra 4. The discrete pixel shader architecture means that the GPU's peak 96.8 GFLOPS can only be achieved when the mix of pixel and vertex shader requests matches the ratio between pixel and vertex shader hardware (2:1), so most of the time the GPU achieves less than 96.8 GFLOPS.
