What does it mean by "Intel HD Graphics"

[Rov3rRepo]

When comparing CPUs, for example the
i3-2330M - http://ark.intel.com/products/53434/Intel-Core-i3-2330M-Processor-3M-Cache-2_20-GHz
--and the--
i5-520M - http://ark.intel.com/products/47341/Intel-Core-i5-520M-Processor-3M-Cache-2_40-GHz?q=Intel%20Core%20i5-520M

I find that the i5 says Intel HD Graphics and the i3 says Intel HD Graphics 3000. One of the Macbook Pros run with Intel HD Graphics 4000. If I upgrade to the i5 (and my GPU was removable) could I put in newer graphics like what goes in the macbook (Intel HD Graphics 4000)?

Intel HD graphics is a small GPU integrated in the CPU itself. It's fine for regular use, not for hardware intensive applications. You cannot remove them, nor can you add them. The difference between the i3's integrated GPU ( iGPU ) , and the i5's is not significant. They were not designed for gaming.

You cannot upgrade a laptop's GPU. Most GPUs in laptops are soldered in.

It means its integrated into the CPU. In order to use it you need a mobo with onboard Intel graphics

Those are the intgrated graphics that come with the CPU, But happens that the integrated graphics of that i3 (HD graphics 3000) perform better than the one that the i5 has, that i5 is older than the i3. But you're on a laptop, and you cant just swap CPUs like that. Is a bit more complicated to check compatibility on laps.
