Most motherboards these days have decent video memory size(1GB, 2GB) on them.
That is incorrect. Motherboards don't come with video memory. The integrated GPU borrows system RAM.
Are AMD motherboards on par with Intel ones when comes to light gaming?
It depends on the board and the rest of the hardware. The integrated GPU, CPU, RAM and the rest of the PC can answer that question. The motherboard alone is just the foundation so it doesn't set any gaming bar on its own. Then price comes into the picture and makes your gaming question impossible to effectively answer. Not going to apply an uninformed blanket answer to such a vague question.
Thanks for your reply. To be honest, I wasn't sure how to put out this question. Yes, you are right GPU borrows system RAM (shared video memory).
So let's put this question in more detailed manner.
AMD Build (excluding graphics card)
1) Motherboard - ASUS Prime X370-Pro
2) Processor - Ryzen 1700
3) RAM - Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3200MHz
4) HDD - Seagate 1TB BarraCuda SATA 6Gb/s 64MB Cache 3.5-Inch Internal Hard Drive
Intel Build ((excluding graphics card)
1) Motherboard - ASUS PRIME Z270-A
2) Processor - i7-7700k
3) RAM - Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3200MHz
4) HDD - Seagate 1TB BarraCuda SATA 6Gb/s 64MB Cache 3.5-Inch Internal Hard Drive
I hope this will put some straight picture. All, I want to know how well gaming will be under these configurations?
Will Intel's HD Graphics will put it to advantage? Also tell me how the procedure works in both builds.
Please tell me anything which I need to include. I want as much enlightenment as possible in this department..
