Difference Between i7 620M and i7 720QM and How to know if you have an i7 620M or i7 720QM on your c

i7-720qm i7-620m45nm 32nm Quad-core eight-thread dual-core four-thread parameters are approximate, I won't write anything else. Because both are mobile series, in terms of performance, the same series 4 cores to dual cores. You know.

If you are looking for high-speed cores, choose 620, and for multi-threaded tasks, choose 720, if you choose one of the two. I would choose 620, after all, the battery life of the notebook is limited, and one with low power consumption and low temperature is more.

i7-720QM cache 6M main frequency turbo frequency up to 45nm

i7-620M Cache 4M Turbo Frequency Max 32nm

It can be seen that i7-720qm in addition to the large cache, the main frequency and turbo frequency are lower than 620m, playing games, etc., generally have high requirements for the main frequency (so the desktop e8400 dual-core game is often faster than some low-end quad-core), 620m will have more advantages, and he is 32nm, more power-saving, and the heating is also small.

But the i7-720qm is 4 cores and 8 threads, and the i7-620m is 2 cores and 4 threads, so it must not be able to run the i7-720qm

Of course, if you talk about performance, the i7-720QM is definitely stronger if you have nothing to say, after all, it is 4 cores to dual cores.

GeForce GT 240M Shader frequency 550 1210MHz, floating-point computing power 174Gflops

GeForce GT 330M Shader frequency 800 1210MHz, floating-point computing power 182Gflops

The rest of the parameters are not listed.

It is made of the same 40nm

Of course, the performance is 330m strong, but that improvement can basically be ignored In other words, 330m is a 240m vest, so if the price is about the same, it is naturally 330m, otherwise it is obviously more cost-effective 240m.

The 720Q is 4 cores and the 620 is dual-core First of all, it's different in the cores, and then the 720Qm has 6M cache and 620M is only 4M! However, the thermal power consumption of 720qm is designed to be 45W, but the 45nm process is 45nm, and the 620 is a 32nm process, and the thermal power consumption is 18W, and in terms of performance, the i7 720qm is higher, but the i7 620m is cooler, and it is energy-saving!

The 720Q is 4 cores, 8 threads, 6M cache, the main frequency is 45nm, and the thermal power consumption design is 45W

The 620 is a dual-core four-thread cache of 4M, with a main frequency of 32nm and a thermal power consumption of 18W

1. In terms of performance, the i7 720QM is higher, but the i7 620M is more energy-efficient.

2. i7-720qm is lower than 620m except for the large cache, the main frequency and turbo frequency are lower than 620m. 620m will be more advantageous, and it is 32nm, which is more power-efficient and generates less heat.

3. i7-720qm is 4 cores and 8 threads i7-620m is 2 cores and 4 threads So in terms of running scores, it must not be able to run i7-720qm

The parameters to look at here are not just the clock and L2! Because 720qm and 620m belong to two different categories! Although they are all i7 series standard voltage processors, the 620M is a dual-core with an integrated GPU, while the 720QM is a quad-core without an integrated GPU.

In terms of games, it is not about the main frequency of the game, because the main thing is to look at the performance of the graphics card, followed by the processor speed and memory. The speed of the processor is not reflected in the main frequency, which is a more general category. These two processors have their own advantages, and the performance difference is not much, and the advantage of 720qm is that it is better to open more.

Corrected upstairs, 620m power consumption 35W, 720QM power consumption 45W.

The flagship model of the 45nm Core, the main frequency of the turbo frequency The flagship model of the 45nm Core, with outstanding performance and average integrated display.

The 720Q is 4 cores, 8 threads, 6M cache, and the main frequency.

The turbo frequency is the largest. 45nm, thermal power design is.

45w620 is a dual-core four-thread cache of 4M, the main frequency.

The turbo frequency is the largest. 32nm, thermal power consumption 18W

1. In terms of performance, i7

The 720QM is a bit higher, but the i7620M

More energy efficient. 2. i7-720qm is lower than 620m except for the large cache, the main frequency and turbo frequency are lower than 620m. 620m will be more advantageous.

And he is 32nm more power efficient.

The fever is also small, too. 3. The i7-720QM is 4 cores and 8 threads.

The i7-620M is 2 cores and 4 threads.

Therefore, in terms of running scores, it must not be able to run the i7-720qm
