Resident Evil 5

Resident Evil 5

Resident Evil 5 is a survival horror video game developed and
published by Capcom. Resident Evil 5 features similar gameplay to
Resident Evil 4, with context-sensitive controls and dynamic cut scenes
also making a return. The player can control Chris Redfield or Sheva
Alomar in a similar fashion to Leon S. Kennedy in Resident Evil 4, with
the same over-the-shoulder perspective.

Resident Evil 5

We ran the Resident Evil 5 benchmark in DX10 mode with all the image quality settings turned down, which just happens to be the default settings of the game.

This game title runs on up to four threads as you can see from the task manager shot above that was taken on a test system that was running the Intel Core i7-2820QM processor.

Resident Evil 5 Benchmark Results

Benchmark Results: We had a gut feeling that gaming performance would be the most impacted area when it comes to performance across different memory speeds on the AMD A-Series APU and we found that to be very true.  Running the 2x4GB 1333MHz CL8 memory kit we were able to get 50.9FPS at a resolution of 1280×720.  Switching to the 2x4GB 1600MHz CL8 memory kit we saw performance jump up to 60.7FPS, which is a performance difference of more than 19% and we could really notice a difference in other game titles as well. The move up to 1866MHz CL9 memory bumped up performance around 1FPS, which isn’t nearly as impressive as the jump from 1333MHz to 1600MHz. Populating all four of the memory slots with the 4x4GB 1866MHz memory kit once again shows that running four DDR3 memory modules does help boost performance over running just two DDR3 modules.  This is true for all memory speeds in case you are wondering.
