Video Cards on a Mac Book Pro

A new / used laptop has been proposed to me with "AMD Radeon R9 M370X with 2.0GB GDDR5 memory, plus an Iris Pro 5200 with 1.5GB shared memory"

Anything wrong with this, off the cuff, for SketchUp, Photoshop, or Twilight?

(I don't know what shared memory means--I can ask the tech guy who's putting this together, I'm sure)

Thanks.

A three year old graphics card with 2Gb video RAM doesn't sound overwhelmingly impressive. But yes, for SketchUp/Twilight it's adequate. It's rated here as roughly equivalent to Gefore 860M which is a pretty good graphics card for laptops.
4Gb video RAM would be better for general performance, especially for new Adobe Creative suite programs.

Iris Pro 5200 with shared memory means that you have a second (basic/lower end) graphics card built into the CPU which shares memory with the CPU. This sounds fancy, but is not helpful in high-end graphics work.

However - theoretically you could set some programs to function off the Iris graphics processor while you utilize the "real" Radeon graphics card for the heavy duty stuff.

Thank you. My current laptop has " NVIDIA GeForce GT 650M 1024 MB Intel HD Graphics 4000 1536 MB". MacBooks have "automatic graphics switching". Maybe the two cards shown here are similar to the set up I have but better cards. It seems that on these machines, you turn "graphics switching" off in order to use the better card only (while plugged in to power) and the switching saves energy otherwise.
