hey there toms hardware peeps,

Im going to build a pc in october-december hopefully and was wondering How much of a difference does hyperthreading actually make in rendering say the i5 was rendering a 10 hour video. how much faster would the i7 be?

CPU: Intel i7 3770K
GPU: Gigabyte HD 7970 Overclocked 3GB
HDD: 1TB Western Digital Caviar Black(will get SSD later very expensive in AUS)
MOTHERBOARD: Gigabyte GA-Z77X-UD3H
POWER SUPPLY: Corsair Hx-850
RAM/MEMORY: G.skill Ripjaws-X 1600Mhz (2x4GB)
OS: Windows 7 Home Premium 64-bit OEM
Cooler: Cooler Master Hyper 212 EVO

More about : 3770k 3570k

Well i can give you a example video editing with Adobe Premiere Elements 8 shows a marked improvement with HT on e.g. encode a test clip of 1GB on a Core i7:

4.2GHz HT on = 312 seconds
4.2GHz HT off = 379 seconds

3.6GHz HT on = 369 seconds

However a lot depends on the software being able to use HT. If I encode the test clip with Premiere Elements 3 there's virtually no difference whether HT is on or off.

so you reccomend 3570K?

Get the i7 buddy, if you are building a new computer, may as well spend that extra 90 bucks for the i7. Since you are video editing, you will be putting the cpu to good use so it will be money well spent. Also in terms of gaming, the i5 and i7 will run identical if not better. An i7 is just a i5 with hyper threading enabled, if you do feel the hyperthreading is holding you back while gaming then just turn it off in the bios and turn it back on while you are video editing. Also you are basically spending 1000+ on a new rig, extra 90 wont hurt

Get the i7. HT will not affect your gaming that you will possibly notice. The main reason why i5 is better than the i7 for gaming is that the i7 offers no performance improvement.

It kinda sounds like you won't be doing much video editing. If you are only casually editing videos (like once or twice a month or so) I wouldn't think the extra power the i7 offers would really be necessary, it may save you a little time here and there over the i5, but if you aren't doing it all the time, it's likely you'll never really be bothered by the extra time it takes.

if you are professionally (meaning for pay) editing and rendering effects to video in software like adobe premiere then an i7 with 16 gigs of RAM is great.

but if you are encoding video taken off your iPhone with media espresso showing you and your friends drinking and ogling some hired stripper at a frat party to upload to you-tube then an i5 with 8 gigs of RAM is suffice.

If all you plan to do is video transcoding, any software that can use QuickSync on HD4000 Ivy Bridge CPUs will be faster than any other software or GPGPU option currently on the market.

I would get it, the 3770. HT helps even in basic tasks. If u encode HD video for 12 hrs, it helps.

Well i don't like ivy period lol but that's because i am addicted to high OC if your not then sure besides you'll mostly be gaming so i don't think the i7 worth extra $100 in your case.

An overclocked i5 will compete with a stock i7 in video encoding. Just get whatever you want you can't really go wrong with either.

dual xeons anyone?
But seriously just get the i7 if £90 isn't a great deal of money. If you're just doing casual video editing though then get the i5 and spend the savings on GPU and RAM or other niceties.
