Intel Core i7-740QM quad core processor
The Intel Core i7-740QM is a four core processor and has a nominal operating frequency of 1.73 GHz. This is still slow but is faster than the Core i7-720QM which has a nominal operating frequency of 1.6 GHz.
Even though the nominal frequency of the Core i7-740QM is just 1.73 GHz, its turbo frequency is very high – 2.93 GHz. Notice that not all the 4 cores can go in the turbo mode simultaneously. In fact only one of the 4 cores can ramp its frequency to the maximum turbo frequency.
The Hyperthreading is enabled in the Core i7-740QM and we can have 8 cores running simultaneously. This is very helpful in the multithreaded environment.
Based on the Clarksfield architecture, the core i7-740QM has a TDP rating of 45 Watts.
The intel Core i7 740QM ( in fact all the 7xxx line processrs) has DDR3 integrated memory controller. Intel’s architecture has started looking good after the Clarkfield and the Nehalem processors with the integrated memory controller.
If you thought that the integrated memory controller is not fast enough , the Core i7-740QM also has 6 MB of L3 Cache. If you are looking for a higher cache you may like to take a look at Intel Core i7 820QM with 8 MB of L3 cache.
Benchmarking scores – The Super Pi 2M takes close to 34 seconds with Intel Core i7-740QM. The Windows 7 gives it a score of 7 out of 10.
