RAM 4x8gb or 2x16gb

[Aspryin]

Weird question popped into my head. is there a perceptible difference in performance between 2 pc's with same specs.

 

One has 4, 8 gb sticks of ram. (4x8)

The other 2, 16 gb sticks of ram.(2x16)

Both dual channel. has there been tests to show this?

future expansion is one argument but not the question I'm looking to have answered.

 

thoughts? videos? benchmarks?

There's about no difference across the board.

On consumer platforms like AM4, lga1151,1200,1150 etc etc, the cpu's only have 2 memory channels, so assuming these sticks are identical in specs, they'll perform the same and 4 sticks put more pressure on the imc so you might not be able to achieve as high of speeds as with 2 sticks and with 2 stick, you'll have room for upgradability down the line, on HEDT/ TR/ platforms that have more than 2 memory channels and can run quad channel memory, you can see a performance improvement.

Not much. I think i saw a video done on this though. It will depend on the rank of the memory sticks. Four single rank ddr4 in dual channel will act as dual rank. Though the difference is hardly noticeable wither way.

In general NO.

But to be specific, the one with 2x ram will run (teeny tiny) faster than 4x ram.

Motherboard will run it at faster memory speed on 2x compared to 4x.
