GL703GM comes with 8th gen processor... but youre right, less RAM and smaller SSD...
That’s got less RAM and a smaller M2 SSD. Also the details and description in the actual text of the advert says it’s a 7th Gen
Extra £70 and you can have 8th gen... https://www.ebay.co.uk/itm/ASUS-ROG-Strix-GL703GM-1060-Gaming-Laptop-Intel-Core-i7-8750H-2-2GHz-8GB-RAM/292612282978?_trkparms=aid=555017&algo=PL.CASSINI&ao=1&asc=53456&meid=9311961df61e42e594f977bb009ca133&pid=100508&rk=1&rkt=1&&itm=292612282978&_trksid=p2045573.c100508.m3226
This was £979 from John Lewis last Friday if you where lucky enough to get one.
I'd have liked to see the current 8th gen processor included at this price. They are reputed to be a significant improvement over the 7th gen (to compete with AMDs current Zen range)
