Recommendations for graphics card in Macbook Pro 16

Don't buy an Intel Mac. Wait until Apple announces their new M1 upgrades this fall.

@Lonn Lorenz  You don't mention whether you are doing 3D in PS. See this forum post ref the depricaion of 3D in PS effective with 22.5.

My 2019 15" MBP has the Radeon Pro Vega 20 4 GB, zero issues. 

@Conrad_C  Your comments are certainly right on for a person who is totally in the Mac system. For me, I use my Intel 2019 16" MBP as a travel machine (not that much travel during covid darn it). When I get home I transfer all the trip work in a LrC catalog to my high spec PC with dual 27" monitors and do the rest of the processing there. The performance of the Intel MBP is fine for me. Heck, even my 2015 MBP 15" was also fine 🙂

@Lonn Lorenz  I mainly use my MBP as a travel machine and general internet browsing at home. I seldome do any heavy duty processing. On occasion while on photo trips I will do some HDR and pano merges. The machine will get a little warm to the touch. I have seldom heard the fan come on, even at low levels. I have read the posts about high fan use and noise. That has not affected me.

My travel machine is a 2019 MBP 16" with the AMD Radeon Pro 5500M. I have never had an issue with that GPU and PS. 

I am on Mac OS 11.5.2 and PS 22.5.1. In the Performance tab of Preferences, the Advanced button shows full CPU utilization except for 30 bit.

If I was going to upgrade to a newer 16" MBP, I would for sure get the highest performance GPU available to hopefully future proof the machine as much as possible. Since, as you know the GPU cannot be upgraded in the machine.
