What does heavily Intel-coded mean?

post #1 of 6
Thread Starter 
Okay first some background. I have an A+ and NET+ cert (just got NET+ =D) through CompTIA and think of myself as a considerably technical person.
I have a very good background in windows.
Ever tried to close windows explorer using the start menu? CTRL-SHIFT-RMB in the Start Menu will let you.
SHIFT-RMB in Windows Explorer will let you open a command prompt in that location without any needed registry changes.


Admittedly though I do not know VB C++.
I do however know InnoScript, NSIS, HTML, CSS and a bit of others here and there. Like a bit of the custom RubyScript for RPG Maker VX Ace, and a bit of JavaScript.

So I am not totally stupid, but I do need some help to understand a thing or two. Had a question and thought to myself "Hot damn! I know just the place to ask it."

So here we go.

1. In one part in this video the guy up at Write Trigger mentions that Dolphin is heavily Intel-coded.
Is there such a thing as Intel-coded?

2. Excluding multi-threading (as I am not about to spend that much on a gaming computer's processor, GPU maybe... Not CPU) what is the difference in performance really between AMD and Intel CPUs. It was my understanding that if the processor isn't engineered by gorillas then (SB/NB/buswidth problems) then Ghz measures the speed of the processor in calculations/ticks per second, or Hz.
Is there other ways people measure this? FLOPS (haha. hmm...)? Seems like there are lots of Intel and AMD fanboys and I keep thinking "surely some of these pseudo technically-inclined folk know what they are saying right?

3. Lasty when a recompiler is translating code, is said recompiler going to do something differently in any scenario depending on the processor? This means brand, socket-type, what have you. As far as I can tell Dolphin runs without a care for the processor brand because (I assume) the architectures are the same: x64.

Any info on this would be very appreciated. Had an account since 2013 and only now using it! lol

Thanks ahead of time

Should be Singlethreaded.

It may mean that it was compiled with ICC instead of VC++.

Hz are just cycles per second, Instructions Per Cycle (IPC) are the average number of instructions executed each cycle. There are some differences between AMD64 and Intel 64 instruction sets: http://en.wikipedia.org/wiki/X86-64#Recent_implementations New CPUs often come with new instructions: https://en.wikipedia.org/wiki/Advanced_Vector_Extensions#AVX2

I'm the wrong guy to explain it but it comes down to IPC (Instructions per cycle). Frequency is a measure of the cycle speed. Even a single core can process more than 1 instruction per second, depending on the types of instructions. Generally Intel CPU's are better at executing multiple instructions per cycle.

See? I knew this was the right place to go to ask this =D
Thanks for the help I didn't even know IPC was a thing. Got my homework to do! Thanks

IPC in itself is totally irrelevant, it's IPS (instructions per second) that is very important. It's possible to have a low clocked high IPC CPU that gets beaten by a high clocked low IPC one, as was the case with Cyrix and P3. Cyrix' CPU's had amazing IPC but because their clocks were stuck at 333MHz and Intel's P3 architecture clocked easily over 450 Cyrix are now history.
