How to find out size of graphics card ?

I am using a Radeon R5 230 graphics card (Caicos, 1 GB) on my FreeBSD 11 
system. I was trying to ascertain whether the system recognizes the card 
as a 1 GB card.

Here's a couple of snips I get.

dmesg | grep -i radeon :

info: [drm] radeon: 1024M of VRAM memory ready
info: [drm] radeon: 512M of GTT memory ready.

dmesg | grep -iE '(vgapci)|(caicos)' :

vgapci0: <VGA-compatible display> port 0xe000-0xe0ff mem 
0xc0000000-0xcfffffff,0xfea20000-0xfea3ffff irq 24 at device 0.0 on pci1
drmn0: <Caicos [Radeon HD 6450]> on vgapci0
info: [drm] initializing kernel modesetting (CAICOS 0x1002:0x6779 

Questions :

a) Is the above sufficient proof that the card is working as a 1 GB 
device ? It's not easy for me to make this out by myself.

b) Are the terms 'graphics memory' and 'video memory' the same ? I ask 
this because booting from UBCD (Linux) on my computer, I vaguely 
remember/think I got to see 16 MB stated somewhere as the size of video 

Thanks for any assistance
