Question #3: Which should I choose; Core i5 or i7?

This video is just a small comparison between the Core i5 and Core i7 desktop processors only in terms of processing power for a consumer, not for a system builder. Core i5 does not have Hyper Threading Technology whereas i7 does. i5 does not feature triple channel DDR3 as well, but for the consumer this makes no major difference. Both of these CPUs are native quad core, whereas the Core 2 Quad is not, i.e. it is two Core 2 Duo dies on the same chip, which is why i5 outperforms the Core 2 Quad in most areas. I actually didn't like the i5 and chose a Core 2 Quad in its place due to the pricing of the Core 2 Quad vs i5.

@nills99 Cool. Just one more thing, most OSes see a thread as a logical core because they can't distinguish between a core and a device which has Hyper Threading - like a Pentium Extreme Ed. looks like a quad-core CPU.

@nills99 This comes from me, who is now an experienced NET programmer. What Hyper Threading does is runs two threads at the one time in each core. It does this by doubling the ALUs in each core.

[jamiebalfour04]

@nills99 A thread is an instruction sent to the CPU which is contained in a process.

@nills99 No, they're "logical cores" - not physical cores. 2 of them are physical, two of them are logical. Hyper Threading works by adding a second ALU to the CPU core.

[jamiebalfour04]

@nills99 That's exactly it. I've now got a nice i7 2600K and an i5 2420M both have Hyper Threading. They're second generation.

@DidntKnowWhatToPut1 *Monday aha

@nills99 Oh...My i5 2500k comes on money, but it says it has 4 threads? Surely it should have 8 then.

[DidntKnowWhatToPut1]

@nills99 Your i5 has hyperthrthreading? How?

[jamiebalfour04]

@nills99 As does mine. As you may have noticed this video is almost two years old. The i5 and i7 have changed since then. We are now even in a second era of Core processors. This video relates solely to the original specification s of the processors.

@drjblf Very difficult question. I have an i7 at 2.8GHz and it runs smoothly with no problems and I recon to be honest the i7 is faster than the i5 with a higher clock rate. It does depend on what you will be doing with it as well though.
