    SU7300 vs SU9600 for HP Touchsmart TMT2 Laptop


      I am about to purchase my Daughters first laptop, who has her heart set on an HP Touchsmart Laptop.

      She in not interested in a gaming PC per se, but I am sure she will end up purchasing some titles that are

      available for the XBOX 360 so she doesn’t have to compete with her brother for playing time,


      HP offers 2 chip upgrades to either the Intel(R)Core(TM)2 Duo SU7300 (1.30GHz, 800MHz FSB)

      or the Intel(R)Core(TM)2 Duo SU9600 (1.60GHz, 800MHz FSB).


      The SU9600 upgrade is an additional $200 and I am not sure what advantages the SU9600 may provide

      that would make it worth the money.


      Question: If these 2 chips were identical in all other ways, how much more speed

      Would that .3 GHZ really make?  Is the 9600 3X as fast or 20% faster?


      Intel furnished me with the a comparison chart that pointed out the following architectural differences


      The SU7300 has 3(MB) Intel Smart cache while the 9600 was 3 (MB) of L2 Cache

      Question: Is there a noticeable speed difference between these two types of cache?


      Instruction Set:

      The 9600 has a 64-bit instruction set while the 7300 has something called an SSE Instruction set extension.

      Question: Would the fact the 9600 has a true 64bit instruction set make a noticeable difference in speed?


      Intel Trusted Execution Technology: 9600 only

      Question: Does this technology increase performance or reliability


      This is not my area of expertise and with getting some informed answers I no matter what

      I choose I know I’ll always wonder if I made the right choice.


      Any advice that you may offer would greatly appreciated.

      Thank you for taking the time to read this post!
