The Lenovo B575e has an AMD E processor family which is better than most medium processor core laptops that have been available for around the same time as it. Most medium processor core laptops that were released more than two years ago have an Intel Core i5 processor family.
This laptop's processor family (AMD E) is in fact the worst processor family across all laptops of a comparable spec and age to the B575e.
The best processor family across similar types of laptop is Intel Core i7-3xxx.
We compared this portable PC to all the other notebook PCs that have an AMD E processor family and we think cheaper portable PCs such as the Toshiba Satellite C50D-A is also worth considering.
If the processor family of this laptop is not good enough for you then you might want to look at the Asus X55A (Intel Celeron) which is also cheaper.
