Nope! Not as far as I am aware of anyway.
However there are simple ways to work it out.
Jaguar (The CPU the next-gen consoles use) will generally top-out with a maximum of 2ghz core clock, much like Bobcat/Brazos, however the optimal clock speed for both Desktops and the PC for this particular architecture will be... You guessed it! A meagre 1.6ghz for various reasons like power consumption.
Microsoft is also using 16 x 16-bit, 512Mb 2133mhz DDR3 memory chips soldered onto the motherboard, this won't change regardless of the rumors as it would mean less performance as some of the chips would be higher density than others hence reducing performance, plus going by the leaked internal shots, Microsoft didn't reserve any area for more memory chips on the motherboard like they did with the first Xbox.
It's 16Gb or nothing folks.
For the GPU Microsoft did state that the GPU is capable of 768 operations per clock and that it was a GCN part.
Thus thanks to the PC's indepth look into the GPU architecture we know it's 12 compute units each capable of 64 operations per clock which gives us the magical 768 shaders.
800mhz, would give us the 1.2 Teraflop number.
Reason why many picked 800mhz is due to multiple reasonings, one is Power consumption and the other is that no discreet GCN GPU has been released at lower than 800mhz. - A 28nm GCN part can hit 1ghz easily enough, yet to meet one that couldn't.
800mhz is a good conservative number to stand- by untill confirmation from Microsoft or a break-down of the consoles when they are released.

Just to add...
There is no 8Gb DDR3 version running at 2133Mhz (1066Mhz real) in the market... so even for 16GB they have to go with 1GB 1800mhz DDR3 (8Gb modules).
Bandwidth drop.
And remember that the eSRAM runs at the same clock of GPU in the Xbone APU... so any increase in GPU clock will increase the eSRAM too... it's not only the GCN... it's a GCN into a APU with 32MB eSRAM... I think the this version of GCN can't reach 1GHz "that" easily.
