Intel x9000 vs 740qm?

I used to have a laptop with the x9000 but now got a laptop with the 740qm. So I'm just wondering if I did a upgrade, sidegrade or downgrade CPU wise.

 

From what I'm seeing on Notebookcheck.net, the i7 is just as fast in single threaded environments, and runs around 40% faster in multi-threaded apps. Cinebench showed the score being 8900 for the i7 in the multi-threaded run and only 5900 for the X9000. So for a dual core, the X9000 isn't really that slow, however it's definitely an upgrade for you sir.

 

It looks as if it wasn't until Sandy Bridge that architectural improvements lead to roughly 20% increase in clock per clock ratio.
Ivy Bridge was another 3-5% in clock per clock increase, and Haswell, up to 5% increase in clock per clock.

Overall, from SB to Haswell, we are looking at roughly 30% improvements in clock per clock ratio on the CPU side, while the iGP was the one experiencing highest increases (starting with SB and now coming to Haswell).

But yes, from x9000 to 740qm, there will be no difference in clock per clock ratio, but for programs that do use all 4 cores, the 740qm will definitely be faster than x9000 due to 2 extra cores.

Still, why hadn't you get at least a Sandy Bridge quad core?

 

Becuase i got the upgrade 3 years ago hehe, but i never really knew if the CPU was an upgrade or not :=)

 

Each arch recently has been 10% faster per clock.

 

In synthetic benchmarks perhaps, but in real-life tests with games and software that heavily use the CPU, the improvements on Ivy Bridge were more in line with 3% (up to 5% in rare cases), while for Haswell, most of the time it was 5% (rare situations showed 10%, and even then those were rare flukes and not a realistic/consistent representation).

As I said... largest increases were seen in the igp department.
