Ask HN: How much does L2 cache impact performance of a development machine?

Hi, I'm trying to decide between two budget laptops. While the lenovo laptop has only 4 gb ram, Im planning to add another 4GB so that is fine. My concern is, I'll be using the laptop for programming. It will mostly involve text processing and occasional number crunching. I will also be using two vms. Both the machines are quad core. Will the 4 mb L2 cache of HP have a greater impact on performance compared the 1 mb L2 cache of Lenovo? This is going to be my primary work machine. I have only worked with thinkpads till date. So I'm also concerned about the comfort level of the keyboards. Has anyone used the HP Pavilion keyboards? Also, I have only used keyboards sans dedicated numeric keys. Both the laptops come with dedicated numeric keys and I'm afraid the keyboard might be a bit cramped. Any inputs regarding this experience would be great! ======================================= HP Pavilion 15-e026AX Laptop (APU Quad Core A10/ 8GB/ 1TB/ DOS/ 1 GB Graph) http://www.flipkart.com/hp-pavilion-15-e026ax-laptop-apu-quad-core-a10-8gb-1tb-dos-1-5gb-graph/p/itmdp2awh5hdhndg?pid=COMDP2AWH5HDHNDG&srno=b_1&ref=bc0646b6-bce2-45d7-81dd-5938a283feda Rs. 37900 +8 gb ram +a10 processor +4 mb cache -dos -it has full keyboard including numeric pad I'm not sure how comfortable that will be -generally dont know how hp products are ======================================= Lenovo Essential G505s (59-379987) Laptop (APU Quad Core A8/ 4GB/ 1TB/ Win8/ 2GB Graph) http://www.flipkart.com/lenovo-essential-g505s-59-379987-laptop-apu-quad-core-a8-4gb-1tb-win8-2gb-graph/p/itmdz5afmgr6facs?pid=COMDZ59FTHJV9T9K Rs. 32707 (at 22% off) + Brand that I have used in the past and trust + windows 8.1 +2 gb video raQ1m * saw a review that said the keyboard was good, It also has full keyboard with numeric keys - 1 mb cache - 4 gb ram - a8 processor
