Tessellation ON vs OFF & Hyper-Threading ON vs OFF comparison

post #1 of 8
Thread Starter 
Intro
I haven't seen a good recent comparison of Hyper-Threading recently, and I haven't seen one that adds tessellation into the mix either.

So I decided to make a quick comparison to show people the performance difference on standard usage of HT on vs off and tessellation on vs off. By "standard usage" I mean, I never turned any processes off, I ran it like I would a normal game with MSN Messenger, etc and antivirus running in the background.

The benchmark used was Unigine Heaven 2.1. The settings were as follows (except for tesselation which was either Disabled or Extreme for each graph below):


The specs used are in my sig, but just in case they change in the future I will add them here.

Test system (my Gaming PC)
CPU: Intel Core i7 920 D0 @ 3.5GHz 1.2v
RAM: 3 x 2GB Corsair XMS3-1600 @ 1656MHz 6-7-7-20-60 tRFC 1T
Motherboard: ASUS P6TD Deluxe (BIOS 0501)
Graphics: 2 x HIS Radeon HD 5870 1GB @ 850/1200MHz
HDD: 160GB Intel X25-M SSD
PSU: CM Real Power 850w Modular
Sound: ASUS Xonar D2X
OS: Windows 7 Ultimate (x64)
CPU Cooling: Corsair H50

Results




Conclusion
Is Hyper-Threading worth it? According to those graphs it has virtually no effect on standard usage. However, using something CPU-intensive in the background would be logical to enable it as you WOULD see performance gains. All-in-all, it depends on how you want to use your processor, even if you aren't using anything CPU-intensive in the background, it does give you a small boost to minimum FPS. But when you take into account the complaints of heat and increased power-consumption that have been talked about, the benefits are not worthwhile.

Nice, i knew that HT wasn't doing alot of things in games and general applications, but i do alot of video editing and all the cores are maxed out during rendering, that's why i leave it on.

Yeah, it DOES work great when it's needed. But for general usage and gaming there's virtually no gains or losses. Though, if you're using encoding or using anything CPU-intensive, then it's best to just leave it alone.

I host several VMs on my sig rig - is HT beneficial? I like keeping this pc as 'green' as possible so the heat savings may be better?

nice to know HT doesn't really help in gaming. learn something new everyday

Virtual Machines. OH YES! Having HT on for many VMs is very beneficial, it allows the cores to switch between threads quicker. In your case there are a lot of threads to cater for with VMs.

Ah wonderful It's what I expected but then again I also expected HT to benefit gaming.

It would if games or graphics/sound drivers used more threads .
