I downloaded Cinebench 11.5, a benchmarking software which is available for both OS X and Windows 7.  I was thinking if the Windows side doesn’t turn out as well as I think it should, then I might just return the 15″ and keep the 13” for its portability and stick to the desktop for more serious gaming.  I figured the CPU would be better in the MacBook Pro but the two year old discrete graphics card in the dv4i would be better than the integrated graphics in the Pro.  Boy was I wrong.

The 13” smoked the dv4i in graphics performance and did a bit better in CPU speed.  By comparison, the 15” bested the 13” as expected.  The graphics auto-switches in the 15” so I cannot test the integrated graphics separately.  The CPU score was much higher.  That i7 quad core really seems to shine.

I also put my three year old desktop in for comparison.  It has an ATI Radeon HD 5770 graphics card (introduced late 2009) and much to my surprise, the 15” Pro beat it in the OpenGL test.  Laptop graphics really have come a long way.  The a6720y has a 2.2 GHz AMD Phenom X4 9550 quad-core processor but unlike the 15” Pro, the former only has 1 thread per core (4 threads total) whereas the Pro has 2 threads per core (8 threads total).  It seems even the 13” Pro is quicker in CPU performance than my desktop.  The 15” Pro just blows it away.

So in short, the 15” Pro can truly be a desktop replacement for me (aside from any Windows specific issues I may come across).  The 13” Pro can’t compete with the desktop in terms of graphics performance even though it comes out ahead in CPU performance.

As long as I’m talking about speed, let me mention the Pros come in and out of standby really fast.  It can come out of standby pretty much as fast as my other computers turn their screen back on after being in Power Save mode.

That makes me think of power consumption.  Here’s the peak wattage used according to my Kill A Watt.  The laptops are measured by themselves.  I measured the computer both with its peripherals (router, external hard drive, external speaker system, and both monitors on) and also by itself.
