Pentium vs Dual Core vs Quad Core

[LastDefender]

In my library there are old games, like Football Manager 2009 and GT Legends.
Light on requirements, but I really like them.

Mostly these games require only one core to run, but what will happen when I'll buy a Quad?

I will need to purchase a new laptop soon or later (my specs: i5 [1.8 up to 2.7], 8 RAM and Nvidia 720), definitely a quad core. Will these games run badly, cause they don't need multi threading and more cores?

Also, I've always thought that a Dual Core is way faster than a Pentium IV, but I could be wrong when we talk about gaming.

Let'say we have a game relesead in 2005 which requires a 2.4 ghz Pentium IV.
A Dual Core will not be a lot faster than a Pentium to run the game, right?

Summary: no, they won't run badly.

Yes, multple cores aren't going to help with anything if the software doesn't support it (unless you're running multiple applications), but an individual core in a modern CPU should still be able to surpass an old CPU.

Buy a really good power supply unit at least around 700 w or higher. I use a 850 w Antek. This the power behind the cpu the gpu.

You REALLY need to read the Conroe and later reviews on AnandTech.

The 2.4 GHz Core 2 Duo outperforms every Pentium IV model, by a HUGE MARGIN!

The Core i5 is EVEN BETTER PERFORMING at just moderate clock speeds, in single threaded workloads!

Edit: At the same clock speed a Core i5 will be 2.97x times faster in SINGLE THREADED workloads, even faster in multi-threaded workloads!

So a 2.4 GHz Core i5 is on par with a 7.133 GHz Pentium IV in single threaded apps.

I'm going to take a look at it.

When looking at your next CPU, take note of its single core performance. That will give you an indication of how strong that CPU is in single core applications.

Yes, [performance] = [clock speed] x [instructions per cycle]

Performance DOES NOT equal [clock speed] alone!

The newer processors, which may be clocked lower, have significantly higher [instructions per cycle] throughput, and thus they perform at least 2.5x to 3.0x better at the same clock speed.

Clock speed translates into both HEAT and HIGHER POWER CONSUMPTION.
