If you are asking about dedicated video memory -
The Iris video chip on that model does not have dedicated (hardware) memory, but shares with the main memory, and uses more as needed, up to 1GB.
i was asking in the intent to play video games on that mac, do you recommend it
Sure.
You also asked the video memory question about 4 months ago.
If your question is REALLY about game play, and how well your MBPro will do games, there's a bunch of threads here that try to answer that to some degree.
Here's one specifically about the Iris 5100 (in the late 2013 13-inch MBPro)

Any one ever played : Grand theft auto V on RMBP?
GTA5 is not yet released for PC. And I highly doubt that the 13" MBP will be able to play it even remotely well.
I saw some where it is possible to play?
like the hacked one

In case I was not clear before, I will repeat it. GTA 5 has not been released on the PC platform (this includes Mac) . There are no versions, legal or otherwise. What you saw was either a trojan or maybe some earlier GTA game.
look on the pirate sites man you will find one with instruction on how to install and play
