We get tons of laptops at the Hardware.Info test lab, and in recent times most of those are of course the ultra-thin, light and sleek models. The Dell Precision M6700 is a completely different beast that way. It's a 17.3-inch laptop weighing in at 4.1 kg, a true workstation for the heavy-duty jobs. It's portable yet doesn't make any concessions in terms of features and performance.
Dell calls it a mobile workstation, a laptop for professionals in other words. This is reflected by the configuration options (you can get up to an Intel Core i7 Extreme edition), and especially by the available graphic card options. You can choose between AMD FirePro and Nvidia Quadro cards, which are optimised for graphical and GPGPU duties.
The test model of the Precision M6700 we received came equipped with an Nvidia Quadro K5000M graphics card. It's currently the most high-end card that Nvidia has for the mobile segment. The Quadro K5000M has 1344 CUDA cores (600 Mhz), 4 GB GDDR5 memory, (1.5/3 GHz) and a 256-bit memory bus. The processor comes from the GK104 Kepler family, and can be seen as the business version of the Nvidia GeForce GTX680M. It consumes up to 100 watts, which is a lot in notebook terms. We haven't tested that many Quadro cards, but it's clear that it's powerful.
The processor in our test model is an Intel Core i7 3920XM, which is one of the fastest versions of the mobile Intel Core i7 Ivy Bridge family. It has four physical cores, but thanks to HyperThreading it can act like it has eight. The processor has 8 MB of cache and runs standard at 2.9 GHz, with a turbo mode of 3.8 GHz. The processor also has integrated Intel HD Graphics 4000, but it's not really relevant here.
