Other laptops with the AMD Radeon R7 M265 suggest many more gaming performances than our test device. The issue: though the GPU would in fact be able of using its DDR3 memory via a 128-bit interface, Dell uses the slower, but cheaper alternate with a 64-bit memory interface.
This leads to an obvious difference in terms of presentation when compared to e.g. the Acer Aspire E1-572G or the Acer Aspire V5-561G (both ship with the same GPU while making use of a 128-bit memory interface) of approx. 20 fps when playing Bios hock Infinite. For several games with particulars set to high (e.g. for Tomb Raider), this make the difference among “still more or less playable” and “strongly stuttering.”
The Dell Inspiron 15-5547 is still well suitable for older games such as Anno 2070 or fewer difficult titles such as Diablo III. These can even be played with medium or high information, using the resident resolution of the display (1366 * 768). More recent games such as robber or Assassin’s Creed: Black Flag won’t run smoothly – not even with everything set to lowest. It does depend on the engine, though, with e.g. Wolfenstein: The New Order running rather well even with medium settings.
Gamers who favor fast action titles or multiplayer games will not be too happy with this machine, with the low frame rates (even for average settings in most games) making it hard to compete with other players using more capable hardware.
While running on battery, graphics performance decreases even further: BioShock Infinite e.g., runs at 32.3 fps (lowly settings) instead of 53.4 fps.
