How to explain to a friend that the Mhz Myth, is a myth?

post #1 of 120
Thread Starter 
Recently I got in a dispute with him. He insists that because a Pentium 4 has higher clock rate than the GTX Titan (seriously), the P4 is faster, and it's cheaper because the Extreme Edition is priced a little less than $200. I shows him a benchmark result of the CPUs getting trashed in real-time graphics rendering, but he insist that they're fake.

In short, he wants a Windows 7 P4 rig, with no GPU and have the P4 run all of the graphics. Mind you that he's looking at a single core P4.

Knowing that he's knowledgeable about cars, I've tried comparing clock rate to the RPM of an engine, and stating that just because an engine screams at 50,000 RPM doesn't make it more powerful than a 5,000 RPM engine. I've also used the cylinders in an
engine as a comparison to the GPU cores. 1 cylinders vs 16 cylinders in raw performance.

But that didn't work.


Or, I could let him learn it the hard way and post the benchmark results of running some games' graphics on the P4.

Crysis' lowest settings at 800x600:

He probably won't listen. Just let him do what he wants biggrin.gif

EDIT: I also forgot to mention that he believes a 4 GHz quad-core only runs at 1 GHz per core, therefore the P4 is superior to even a super clocked i7. (1 + 1 + 1 + 1 = 4, right?)

He's not that bright when it comes to computers...

Seems like your friend is just dumb, no solution for that.

I don't think he is only dumb at computers it mostly reflects him being dumb at everything biggrin.gif and the refusal to believe

Hahah... I've seen/heard people say that it's 3.3*4 for example.. But I'm sorry, that is just dumb. I can see where he gets the idea but if it's the case of old technology being superior to new technology...

Wow.

You can't fix stupid. Let him get a Pentium4 with no GPU, he'll see how well his computer runs when he gets it.

Try this: MHz are like the number of steps a person takes per second, but IPC (instructions per cycle) are like how long a person's legs are. A person who takes slightly more steps but has much shorter legs won't get as far as a person taking slightly fewer steps with much longer legs. That's why a higher-clocked Bulldozer is still slower than a lower-clocked i5.

Just let him spend the cash on a crappy system then you can tell him you told him so. That's got to be worth it.

Sometimes, you can't fix dumb people.
