I had one in for review and the GPU ran at up to 1845MHz during games according to GPU-Z. Pretty consistently too, rarely dropping below 1800, while the CPU was in 15W TDP down mode. As far as I recall, it was ostensibly a Max-Q. Furmark would drop the speed to something like 1300 - 1400. Still more than the advertised 1245Mhz boost clock. 1024 shaders according to nVidia driver. Whatever this is advertised as, it's much ado about nothing. This appears to be a GPU that, in reality, runs WAY faster than advertised. Unless GPU-Z was wrong. I downloaded another utility for comparison. Same thing. Something like 300MHz idle, but 1800+ sustained boost. Maybe notebookcheck should take another look at a review unit, rather than getting upset about spec sheets. Incidentally I had it set to GPU only mode, hybrid turned off.
