I am researching upgrading my computer. The Intel I5 don't have Hyper Threading the I7 does. What is the benefit of the more expensive I7 Hyper Threading.
P.S. I'm not a gamer but perhaps am heading that way..
To put it simply, hyper threading makes the CPU slightly better at doing multiple things at the same time.
It isn't really essential for gaming...
For gaming, the main thing you want to focus your effort (and money) on is the graphics card, everything else is important, but takes a secondary role to that.
Pretty much what ocalhoun said: It's better if it has it, but it's not all that important.
hyper threading is only an Intel trade mark it is what people in the microprocessor industry commonly refer to as Simultaneous Multi-Threading per core
hyper-threading allows a single PC microprocessor to behave like two or more PC microprocessors.
Hyper-Threading allows various parts of the PC Microprocessor to work on various tasks at the same time.
it was brought to the market by Intel which they did for the first time in 2002 when they introduced it to the consumers in an Intel xeon PC microprocessor.It was supported in windows from windows NT 4.0 onwards and is also supported in most Linux and UNIX variants. the Pentium series were the last to have hyper threading before it disappeared and reappeared in core i7(Nehalem) in 2008 which had 8 threads
