i5 2500K or i7 is a must?

Post by jelmet » Tue Aug 23, 2011 3:25 am

Hello everyone,

I'm about to build a new computer mostly because of Nebula.
I'm not going to have as much $ as I thought I would have so I'm trying to save some where I can.
So the question is:

For Nebula, does the multi-thread thing on the i7 is really worth it?
If you tell me I'll have much more power with an i7 running the same clock as an i5, I'll go i7, if you tell me it's... 20% better with the i7... I'll go i5... you've got the idea.

Thanks!!!!

Is i7 a must? I'd say no. But there is a difference. For me I'm always chasing the mythical dragon of CPU and I can always use more so I just buy the most powerful chip I can possibly afford and build the rest of the machine around that.

Hum, I agree with you, but I would love the have some numbers...
Maybe GianCarlo will stop by and shed some info about that.

The i5 2500K benchmarks are a bit better than the slightly more expensive and older i7 950. 7329 VS 6682 according to the link below. I'm sure you can find some comparisons online. Most i7s score lower than the 2500k. The i7 2600 is not much more expensive and does offer a significant performance boost so you might want to consider that?

Get the best CPU you can afford. No matter what you get, you will want something better in six months anyway.

I know I should get the best CPU I can... just curious how well the 2500K perform compared to the 2600K with nebula.
Those benchmarks don't impress me, I care about real world usage tests.
But thanks anyways, I'll go 2600K.

I do think the 2500k offers the best value for money. You can get around the same performance as a stock 2600 if you overclock it. I'm going go for the 2500k and spend the difference on a small ssd to cut loading times. Also, next years Ivy bridge cpu should fit the 1155 socket, so I might be able upgrade the cpu and get an even faster one by then.

I never tried i5, so I don't know... i7 should be twice faster if you use the same clock and architecture. I'm using 960, though

I have both i5(2,27) and the i7 (3,4). I can't give you a "scientific" answer, but my subjective impression is that the i7 is much faster. It's also very easy to overclock. If you are mixing @96kHz you will need every tiny bit of cpu power you could use.

My perspective experience: i7 hands down.

My personal experience: i7 to save your days.

I run two i7 2600k side by side. I spend about 1200 on each machine. they have 16gb of ram each and run SSD for nebula.. I am VERY happy running one as the nebula server. I usually mix at 1024 samples and I have NO problem running ALL the reverbs and consoles I want in real time. God bless nehalem

Do you think you could share what is a real trackcount for Nebula with let's say, AlexB consoles on a 2600K?
I mean, I can run something like 6-8 consoles on a Duo Core and could run 12-14 on a Quad 2.4, both running MacOS :D
