i7-620m ---> G73Jh

Anyone have one of these? I wan't to put one in my G73 but can't seem to find any place that sells them online aside from some foreign company on ehay. If you made the switch, how does it perform compared to the 720qm?

 

It's a dual core, not a quad core. So in multitasking and some games, you will probably note a performance decrease, but I don't think the difference is too great. Why would you want a i7-620M over the stock i7-720QM?

 

A higher clocked dual with HT is really close to a true quad. My line of thinking is more (8) threads doesn't necessarily mean better for gaming, expecially when those threads are lower clocked. Technically I will lose 2MB of L2 but gain in a ton clockspeed and thermal headroom. Your also talking about a 45nm quad-core w/HT vs an 32nm dual w/HT.

Under load with 4 threads active, the default clock is 2.66Ghz on the 620m and has the potential to boost up to 3.33Ghz with a single thread.

The 720qm on the other hand has a default clock of 1.6Ghz tops with 8 threads active and can only go up to 2.8Ghz with a single thread.

Playing around with games and benchmarks on my G73, the highest freq I seem to obtain is 1.73Ghz because there are 3 or 4 threads that appear to be active.

 

From what I've noticed using my G73 that its gaming performance seems GPU bound, not CPU. You may get marginally better per-thread performance with a higher-clocked dual core, but you lose 4 overall threads.

 

No, it isn't. Even a Q9000 will easily beat the 620M, in a multithreaded app.

 

I kinda doubt that, but I won't know for sure until I can get my hands on one

 

Depends on the game you are playing.
