Celeron vs Sandy bridge?

Well i've just bought a new laptop with a sandy bridge i5, and I was wondering how much faster it is going to be then my current laptop (which has a Celeron dual-core).

So in short, my question is: How much faster do you think a (dual core) sandy bridge processor would be, when compared with a celeron (dual core)? (assuming they had the same clock speed)

Thanks

(Sorry if I posted this in the wrong place. I'm new here )

 

Comparing a Celeron to a Sandy-Bridge Core i3/i5/i7 CPU is like comparing an old Toyota Camry to a Ferrari. The Sandy-Bridge will be significantly faster.

But be aware that a speed upgrade to a single component in your system will not necessarily yield real-world performance gains. Application performance is controlled by the speed of the storage system (HDD or SSD), so upgrading the CPU will give you only small gains in that area. Gaming performnace is typically controlled by the power of the GPU, so upgrading the CPU will only give you small gains in this area as well (for most games).

You'd only see massive gains in performance when you're running applications that specifically pound the crap out of your CPU and take it for a spin... applications like CPU-based video encoding, or massive number crunching applications like cryptography.

 

Thanks a lot for the post. Good to hear it's going to be a lot faster then this

Do you know if anyone has ever written down exactly how much faster the different series of processors are to each other?

For example, I have heard people say that sandy bridge is 10% faster then the old "i" series (clock for clock).

I suppose I can just wait and see though. Only a couple of weeks before it should come.

 

+1 to what kent1146 said, it is incomparable. Even assuming your Celeron is based off Core 2 architecture, clock speed for clock speed it surpasses by a longshot. And more "GHz" will only yield performance gain in applications such as rendering.

 

Can I ask what laptop you bought?

 

A lot will depend on what you do. While the SB certainly offers more oomph, many things do not use much CPU power. There the hard drive speed will be more relevant.

 

I don't know exactly how much faster Sandy Bridge is but it's A LOT. The SB quad cores are about 200% faster (2x) than last year's i-series. (according to early benchmarks) (I'm comparing the MBP's geekbench scores cause that's the only thing I remember)

Yeah... what kent1146 said... it's like comparing a 1980 Toyota to a Ferrari.

You will notice a significant boost in everything. Well, I did when I jumped from core2duo to core i5.

 

Celeron hands down will smoke Sandy Bridge!!
