is Hyper threading really that necessary?

[007agentHP]

hello, i want to just bring something up to hopefully spark a conversation. i right now am using my secondary rig because my first one is down, and the specs u need to know are it has an i5 4590, 280x and 8 GB ram. for my main rig, i got a i7 4790k for multitasking. but just before, here was all the programs that my secondary rig was running without any lag at all!

sony vegas pro 12 rendering a 25 minute 1080p 30fps video

running a 2 person minecraft server

running a maxed out minecraft with high render distance

running skype

running fraps and recording

running chrome with 5 tabs open.

running 2 player hamachi.

so the main question, the quad core i5 could handle all this without any lag, on 8 gb ram (even tested with a more intense game, allbeit no server runing, battlefield 4), what is the point of going for the i7 4790k?

Better performance when doing heavy multitasking, faster rendering of videos.

 

I myself kinda wish I went with the i7 4790K instead of my i5 4690K so I could do more stuff when rendering videos in premiere pro without getting a pretty large performance hit.

Better for multitasking.

but i never got that performance hit, which was what scared me. battlefield 4 still ran on high at 60fps smoothly. i was running all that, and there was no performance hit.

Linus has a good video on it

unless your CPU usage is really high, youre not going to notice any with a 4690k or 4790k

the difference is that rendering a video will take 30% less time, running many programs at the same time will not create lag, and you have more threads to allocate in case you want to render while doing other taks

because if you render on all cores, your system will lag no matter what CPU you have

with 8 threads you have more flexibility

Hyper threading offers absolutely nada for single-threaded tasks or other thread limited tasks like gaming (unless you've got something like an i3 that only has 2 cores and the game can easily make use of 4 threads).

 

However for real multi-threaded tasks it can be a huge difference. Video encoding and rendering are some good examples here.

When I render a video my framerate in tekkit classic (modded minecraft 1.2.5) drops down to 20-40, when normally its 100+..

I like saying things so I can get my post count higher. 

 

When you make use of the whole CPU Hyper threading will perform similarly to having those extra cores.  if you are not maxing out that i5, the benefit of an i7 or Xeon won't be significant.

for rendering I really want a 5690x because I feel like my i7 4770k @4.7 is very slow

Even a 5820k is a large improvement over 4770k.

Or you could save money and buy he 5820K and put that money in a new graphics card ...

Hyper threading isn't like adding extra cores, what it does is streamline the process which can feed the CPU faster.

I feel like the 4770k is very very slow and the 5820k is only 2 core 4 thread over it so I'd need the 5690x to get the difference I want.

I am very difficult but yeah I like when stupid things are done as fast as possible.

Here is another way to look at the first point. It has 50% more cores and threads.

 

Also agreed, I went with a 5820k cause the cores/$ ratio is too strong.

@Casperian yeah I'll probably end up going with that too.
