Tom's Hardware posted a review on the Zotac Gaming GeForce RTX 2080 AMP
A quote from the article:
Size isn’t everything, but a bit of extra heft sure doesn’t hurt when you’re trying to keep a 13.6 billion transistor GPU running cool and quiet. Zotac’s Gaming GeForce RTX 2080 AMP is much larger than Nvidia’s Founders Edition model, measuring 12.13 x 4.45 x 2.24 inches. Of course, that makes it about two and half expansion slots thick, tying up three slots on your motherboard (along with more space in the other direction due to a taller backplate).Zotac Gaming GeForce RTX 2080 AMP Review
