That leaves you with two memory slots available to expand the iMac further. Our review iMac 2019 came with 16GB, fitted as two 8GB modules, just like in the Inspiron 7000. Its clock speed even matches the iMac 2019’s, which Apple has upped to 2,666MHz in 2019 models. The top-of-the-range Inspiincludes 16GB of DDR4 memory. That’s sufficient for light use, but 16GB would be wise for creative work, or just to avoid macOS paging things out to disk when you have a lot of apps and documents open.

Thanks for the (not much) memoryĮven in 2019, all three 27-inch iMacs 2019 come with 8GB of RAM to start.

At 1,920 x 1,080, the mean average rose to a very comfortable 77 fps, though this particular game’s toughest scenes still see dips as low as the high teens. Really, with iMac 2019 gaming you’ll get much better performance by lowering resolution instead of effects quality. Switching to the game’s ‘High’ quality preset brought frame rates up to 23 and 33 fps, the latter (4K) approaching playable levels. In the Rise of the Tomb Raider benchmark, with all effects turned up to maximum, the mean average frame rate at those resolutions was just 19 and 27 frames per second (fps), respectively. When connected to the same iMac, the eGPU took 10 minutes and 42 seconds to finish the task.Įven so, gaming at 5K or even 4K resolutions isn’t advisable even with a better GPU like the Vega 48. That’s actually more than a minute faster than when we connected our Thunderbolt 3 eGPU, which contains an AMD Radeon Vega 64 card. The iMac finished this test in 9 minutes and 19 seconds. To test the capability of the optional Vega 48 GPU, we encoded our 2.5-minute, effects-laden DaVinci Resolve project to a 720p, H.264-format video file. Some software requires a powerful GPU instead. Churning through huge amounts of data doesn’t always depend on CPU capability.
