To whoever who is going to preorder! I was so excited when I see this slide and wanted to preorder one immediately: It looks great with a stylus, and with the touchscreen and tablet mode almost made me preorder one. Then I realized, the Macbook Pro in the ad is running Mavericks.. it's 2012 version which probably come with a CD ROM and Hard Drive and 4G of RAM. And a further evaluation of it's specs prove me right... Some comparisons: SurfaceBook 1499 USD: i5 CPU - Skylake, i5-6300U, Integrated HD 520 Graphics 15 W TDP Ultra low wattage processor 2.4GHz to 3.0 GHz Same lineup of processor with the Macbook Air (TDP) 128 GB SSD 8GB RAM 3000*2000 Resolution Retina Macbook Pro 13 inch 1499 USD i5 CPU - Broadwell, i5-5257U, Integrated Iris 6100 Graphics 28W TDP low wattage processor Have the highest end for integrated graphics in the 28W line up Graphic performance > HD520 256GB SSD 8GB RAM 2560*1600 Resolution Short conclusion: The retina Macbook Pro have a larger SSD, Faster CPU and a better integrated graphics. The Surface Book is hybrid, higher resolution and have a stylus. Comparison for the high end: 2699 USD Surface Book: i7 CPU- Skylake, i7-6600U, Integrated HD 520 Graphics 15 W TDP Ultra low wattage processor 2.6GHz to 3.4 GHz Same lineup of processor with the Macbook Air (TDP) 512GB SSD Have an dedicated graphics card (GTX 940M/950M-predicted) 16GB RAM 3000*2000 Resolution Retina Macbook Pro 15 inch 2699USD (Compared because same price) i7 CPU - Haswell, i7-4980HQ, Integrated Iris Pro 5200 Graphics 47W TDP processor 4 cores and 8 threads Have the highest end for integrated graphics in the 47W line up 1 TB SSD 16GB RAM 2880*1800 Resolution Dedicated graphics card R9 M370X with 2GB GDDR5 Short conclusion: The retina macbook pro 15 inch hae a higher performance in both processing speed and graphics. The surface book have an advantage of the stylus, higher resolution and its hybrid form. Why is it a low power processor? 13 inch laptops which boasts a 12 hour battery life, will have to use the lower wattage to increase battery performance. The surface pro 3 i7 have the following specs: i7- CPU Haswell, i7-4650U and Intel HD 5000 (15 W TDP), boasts a 9 hour battery life. Macbook Air 2014 version also have the same high end i& CPU, boasts a 12 hour battery life. How do you judge processors? Judge it based on the TDP. In recent generations the processors that are low TDP is very unlikely to beat a processor with a higher TDP. 4th gen is Haswell, 5th gen is Broadwell, 6th gen is Skylake. All the processors will be separated into three groups: 15 W TDP Ultra Low power Macbook Air standard processors 28 W TDP Low power Macbook Pro 13 inch standard processors 37W 2-core/47W 4-Core TDP High end Macbook Pro 15 inch standard processors How do you compare? For the processors of same TDP but different generations, the NEWER generations will beat the older generations. For processors of different TDP, the processors will be faster in the one with a higher TDP (REGARDLESS OF GENERATION) Hence the processors in the SurfaceBook will NEVER beat the ones in the MacBook Pro. How Microsoft can claim that it's faster by two times than the Macbook Pro? Passmark Benchmark: Intel HD 520- Expected score 500 - Surface Book i5/i7 Integrated graphics HD 5000 - 596 - Macbook Air 2014 HD 6000 - 796 - Macbook Air 2015 Geforce 940M - 869 - Expected in Surfacebook USD 1899 Iris 6100 - 947 Retina MBP 13 2015 Iris Pro 5200 - 1180 Retina MBP 15 2015 integrated graphics Geforce 950M -1366 Gefore 960M - 1574 R9 M370X - 1985 Retina MBP 15 2015 Discrete graphics Microsoft's comparison is that you have to get the $1,899 Surface Book to get "double" the graphical power of even the cheapest MacBook Pro, which goes for $1,299. Only with the discrete graphics it is possible.. :l But not two times. And the integrated graphics is so mediocre (HD520) and can be find in any of the ultrabooks that are released recently. So don't expect great performance in tablet mode (without the discrete graphics). Conclusion: The SurfaceBook is a great laptop with great design, but for the specs it offers, it is too expensive, especially the low power processors and very mediocre integrated graphics. Crossing my fingers to see the reviews soon.
