Had no chance to test it but i think your right. A quick look at a TDP comparison (45 to 2450M's 35) tells me it has to be faster. Much newer CPU but higher TDP -> should be faster
Try the i5 6300hq and tell me your opinion...
No real difference... much better TDP and FSB instead of DMI are the only things 6200U is better though i am sure that 2450M is much faster in the end cause it's nearly always in overclock (2.9Ghz)or turboclock (3.1 Ghz) mode. 2450M is the fastest mobile i5 'till today in my test cases because it's not U but M
