However, if my sources are right, Spartan is not IE 12. Instead, Spartan is a new, light-weight browser Microsoft is building.
Windows 10 (at least the desktop version) will ship with both Spartan and IE 11, my sources say. IE 11 will be there for backward-compatibility’s sake. Spartan will be available for both desktop and mobile (phone/tablet) versions of Windows 10, sources say.
I’m guessing not having to worry about supporting websites built for older versions of IE will make development a lot easier, and the change in name is a huge PR bonus.Shipping two browsers on Windows 10 seems a bit… Well, I don’t know, convoluted. Hopefully we’ll be able to kick IE right off our computers.
is the number of processor cores increases rapidly, while no big advances in single thread performance has been achieved lately.
This trend is based on
1. the engineering effort to achieve even more IPC gets bigger and bigger, the performance per watt ratio gets worse and worse
2. battery lifetime has become a selling point
The single thread performance to power consumption ratio gets worse with increasing single thread performance.
ARM’s BIG.little approach (http://community.arm.com/groups/processors/blog/2013/06/18/ten-thin…) takes this fact into account. The second figure illustrates the power consumption over performance of a high IPC design vs. a low IPC design. The low IPC design achieves a significant better performance per watt ratio than the high IPC design.
I hope Microsoft Spartan is a reaction on this trend as the Firefox Servo rendering engine is.
Update – Sorry, but I forgot to mention the Google Blink engine.
