The part of decrease is real. I wrote a quicksort program in c using openmp, and put an argument to limit the thread number to the value I want. Running this on a i7 dual core 4 threads was way faster on 2 threads than on 4. That's because in 2 threads, when I split the program in two cores, they execute it directly, but on 4 threads, they where always changing process, and that made them slower. Hyper-thread is good for very small, parallel tasks, and not to split heavy ones.

Wow! I have a great example of this. Just last week, I took a process I have and made it into a multithreaded process. It's the building of a navigation mesh for pathfinding in video games. The process I started with was single threaded and it took 52 minutes to build for my huge level. I made it work on building two tiles at once and this brought it down to 26 minutes exactly. Then, I made it use 4 threads and, as expected, the build time dropped to 13 minutes! WOW! I know that it's only a quad core so, if I try for more than 4 threads, it's going to try to use hyper threading. What the heck, let's try! 6 threads....12 minutes!! :( 8 threads, 11.5 minutes! HA... hyper threading didn't help me much at all. More CORES freakin' rules!

I remember the advent of dual cores, it was a massive breakthrough in computing for the average consumer. At that point in time waiting for common things like browsers, media players, and folders basically went extinct. The ability of the computer to have a free processor open for you to access those things instantly meant that it didn't have to drop background processing to open the program you'd requested. Even going from a 3.8ghz single core to a 1.86ghz dual core is a big improvement just because of this fact.

Just in case people are interested, this very good analogy more accurately describes Super-scalar processing techniques in general, of which hyper-threading is just one method. Others include things like out-of-order execution, more efficient branch prediction and register renaming, all of which try to eliminate different parts of the processing pipeline from being left redundant.

Also a cache is many orders of magnitude faster than DDR4, that is the whole point of a cache. Trust me dude, I just had to build a CPU from scratch for school, and understanding cache operation was a big part of this.

It only works when you don't have enough single cored load,, GTA4/5 for example, will load CPU so much, that for a 2core-4thread can't get any time free from work, and Windows will park half it's cores(the actual physical one, as dumb as it sounds) and try to boost frequency as high as it can to overcome the load, reducing performance in half, leading to stuttering. FC3/4 OTOH, just lightly loads all 4 threads, so there are all 4 threads always available leading to smooth gameplay, no matter how long you play.

JFTGames Yah wouldn't multicore be virtual machines and screen recording while multithreaded would be like video editing? Because "kemoka77" said the 8350 "trashes many i7s in multithreading" and I don't believe that.

I have an AMD-FX 6120 in one of my computers. Task manager says it has 3 cores and 6 threads. Hyper-threading is an intel technology, no AMD processors have it. Download CPU-Z, it will say your CPU has 6 cores and 6 threads. Task manager is wrong, probably built to read intel CPUs.

Even games won't utilize 2 or even 4 processors at all times even with (or without} threading.. If you understand the point he is making. A game is an essentially an application, and it still spends time waiting for the next move before it can process the next thread. It can (and does) try to predict what the next move will be, but it can't process the next frame until it knows what it is going to be. So obviously the game is not using all 4 cores all the time. Because there aren't threads waiting in line, as the man said. Then when the next frame is known it can use however many processors it wants to to display the next frame or action. That's why it helps to run extra GPUs to add the speed boost necessary for fast seamless action.

@TechQuickie July 2018 - I have been playing Counter-Strike GO with hardware monitor running in the background. I have an I3 7350k Kaby Lake cpu which is a 2 core with hyperthreading. I do notice the two hyper-threading cores are quite busy while I'm playing so I definitely think there is a benefit to having those extra hyper threading cores while playing games. Of course it is not as good or faster as a more expensive chip with more throughput and more cores.
@DrRChandra

Think of it more this way...HyperThreading uses pieces of the processor which are not otherwise in use. For example, if an instruction for a floating point multiply of one floating register with another is followed by a memory fetch to an integer register, while the FPU is computing the product, the memory fetch circuitry would be otherwise unused/idle. So instead of waiting for the FPU to finish, the memory fetch goes straight to the ALU, thus executing a floating multiply and the memory fetch at the same time. Obviously, this can only be scheduled thusly if there are no conflicts, for example the floating multiply cannot reference the same memory area as output which is being fetched in the next instruction (which is why above I specified the FPU was working with registers).

For those with a bit more interest, a single-core CPU with Hyper-Threading has a single processing core, or "1 mouth" as per the analogy, but it has a duplicated set of registers. This added set of registers is the "2nd hand" in the analogy.

1:05 I think you're describing superscalar processors more than hyper-threaded ones (Intels are superscalar since P4 architecture (and I don't mean Pentium IV)). HT uses concepts of superscalarity, but for improving performance of different tasks on a processor. It would be better to describe HT as doing two different things at a time: eating and writing a blogpost maybe? And sharing resources not needed by the other task (left hand for eating, right hand for typing).

I like this format for AFAP better than the newer format. This style is slower, less stuff thrown in your face, and easier to digest (see what i did there? lol). It seems like they are trying to make their newer AFAP videos shorter and still contain the same amount of content, if not more...its a little overwhelming.
