Whatever the case, I'm positive that dolphin won't run faster in a side by side comparison of exact PCs one with HT and the other without. Unless you can give me a reference to some proof otherwise.

Unless you can give me a reference to some proof otherwise. It probably won't, but it makes your PC much better for everything elsr, so unless Dolphin is literally the only thing you ever plan to do on the computer which is demanding, it's a definite advantage. Also, that's real rich coming from someone that just comes in saying HT is something completely different to what it actually is, also without any proof. I'll see about disabling HT on my computer and doing the Dolphin benchmark to see if it makes any difference. 02-09-2017, 05:13 AM
Wikipedia is not an academically accepted source. You would need to do more research than that, unfortunately :/
If two people build the exact same computer, and both install the same OS image, then the computers will have identical performance. If they start loading different programs onto the computer, the overall performance of the computer is still the same, there's just more programs taking up the limited amount of processing power. So then if they both run Dolphin, one may seem faster, only due to having less background processes stealing system resources. Hope that helps you clarify your arguments in the future As for hyper-threading, it can help by putting background processes onto the logical cores instead of the physical cores, allowing the physical cores to spend more cycles on Dolphin. I would need to dig around in the forums, but I'm pretty sure there was somebody who did the test already with Hyper-threading turned off on an i3 and noted that their Dolphin performance was lower than when Hyper-threading was turned on. 02-09-2017, 05:14 AM

It's really no big deal if you don't believe me or what Wikipedia says, because we all run our PCs a different way than other people. That's why some peoples PCs are faster than others even if the hardware is the same. It's just logic, pure and simple truth. Because we all know Wikipedia is the complete truth all the time, right? In all seriousness, it is right in this situation, but I still roll my eyes when people say they have 'proof' that only comes from Wikipedia. However, in the case of Dolphin, I do wonder how much a dual core hyperthreading gains just by having the background tasks on the logical cores so they run when the physical cores (running Dolphin) aren't currently working. I imagine it to be somewhat toned down from the difference between a dual and quad core processor even though Dolphin can only really run on two cores. Which is why I'm testing it.

Look guys you don't know me and I don't know you but I know that I've have studied countless books, websites and had actual experiences on these topics, A+ certification books are a good place to start if you doubt what I say. Like I said before, I only gave my input because I know what I'm talking about I'm not some noob that's just now learning about HT. Also I wasn't arguing, I was stating a fact. I believe the argument was from whoever started to doubt what I was saying. 02-09-2017, 05:37 AM
Here's a YouTube video you might be interested in on the topic. It's had 23K likes and 1.2M views. https://youtu.be/wnS50lJicXc

I don't have a problem with your later post, but your first post was misleading at best, because it makes it sound like a Logical core only acts if a physical core is completely idle and otherwise just waits in a queue, which is just false. ANyway, here are the benchmark results from my little test, I didn't bother to set them up properly so it's not exactly scientific, but there is a slight difference that gives the advantage to HT. With Hyperthreading: Image: Image: So yeah, maybe not much of an advantage, but it does have one. (Don't ask me why AMD markets this chip as 'quad core', because I've been asking myself that since I got it...) 02-09-2017, 09:00 AM

Hey guys,
The reason I mentioned hyperthreading was just because it seemed to be a selling point for the new Pentiums. It would help me out since I was planning to use the PC for multitasking as well, not just Dolphin. From my experience with hyperthreading in a 2x Xeon workstation/server, I did not see a noticable difference with hyperthreading on versus hyperthreading off, however the emulation on the Xeon CPUs was not very good either. Regarding the graphics card, I will take admin89's advice and test out the built-in graphics if I get the G4620. In my current laptop, which has an Nvidia GeForce GT 650M graphics card, the performance is just a bit lower than that of the Intel iGPU 630, and it seemed to handle 3xIR well when I tried it out a while back. (There's always the option of course to use 1080p for GameCube/most Wii games, and 720p for graphically intensive Wii games until I can get a dedicated graphics card). http://www.videocardbenchmark.net/compar...5B%5D=3540 I guess a good question would be is the $45 price increase on the G4620 worth it? Since if I were to go with that option, I most likely wouldn't be able to fit a graphics card into the budget (unless I go with an older used one from eBay), but it is the newest Kaby Lake architecture, has hyperthreading, and has the 10% performance boost.

It really comes down to the individual. Will you pay more even if it does nothing for your performance? As for me I would rather spend my money on more actual cores or a higher boost clock. Or maybe it does make some difference. Dolphin has been a dual core application. Should they add support for HT in it? Probably not. Because it's more likely that you'll be using your PC for just running it at that moment and not anything else, thus only getting a real speed increase from real CPU cores. Quad Core support would definitely be a wiser improvement. 02-09-2017, 10:36 AM

That's really not how Dolphin works. I know the devs have said many times that two, maybe three cores is the highest they can go without causing more problems than benefits, and Dolphin already does that. It even says that in the FAQ I think. They can't just 'add quad-core support'. Also, sure, two benchmark runs with the Dolphin benchmark tool are totally opinion based, even though I spent far longer running them than you spent looking something up on wikipedia To the OP, check this video for seeing just how much difference HT can make to a CPU with few physical cores, and some scenes that show how close it is to an i3 in most situations due to the Hyperthreading. You won't have seen that much of an improvement with Xeon's, they have so many cores anyway. Hyper-threading is mainly useful for CPU's that only have a few physical cores.: https://www.youtube.com/watch?v=H-aP0JqJkJ0 Ok, I'm done now. Not going to waste any more time in my life trying to convince you. |
