Core i5 related question.

lolzololz said:

It often seems like a single one of my cores on my core i5 takes a lot of load, and the others very little. Like, I'd be playing a non-graphics intensive game, and a single core would be one 90%, and the others maybe 10%. Is this normal?

System:
-Intel Core i5
-HD 5850
-Gigabyte p55m-ud2 (motherboard)
-Western Digital Caviar Black
-Corsair 650TX (650 W)


I recently upgraded from an old AMD build with a 1.6 ghz processor, so I don't know if this is supposed to happen or not on four core processors or not.

I take it you have an i5-750?

Download Cinebench(it is a free benchmark) and run the multicore benchmark on it, and compare to reviews from the major sites.

I got 4289 on the "Single CPU Render Test" and 14126 on the "Multiple CPU Render Test". Is that up to par with other core i5-750s?

Depending on your operating system, and the game, this is entirely normal. Pre-Vista/Win7 Windows wasn't even threaded for multi-core. So even system tasks would all get devoted to a single core.

And many, many games are still this way. They'll grab one core and use it for every computation they need done.
