Comparison between Intel i7-2760QM vs i7-2820QM

Hi guys, I need you opinion in choosing between those 2 processors.

I found this promotion for Clevo P150HM. Currently it is equipped with Intel i7-2760QM but they give free upgrade to i7-2820QM.

As far as I understand, the i7-2760 is the newer generation compare to i7-2820 and it has higher clock speed, but the i7-2820 has better better L3 cache.

So I want to know is the free upgrade actually worth it, what are the benefits from upgrading, which has the best value for money and if you guys have to choose would you go with the i7-2760 or i7-2820?

Thanks

 

Both of those processors are "second-generation" Core i7 variants and are architecturally identical. The i7-2820QM is slightly faster than the i7-2670QM. If the upgrade is free, get it.

 

Passmark processor benchmark:

2820QM: 7462
2760QM: 7575

Pretty much identical.

 

Thanks for the info guys... Really appreciate it

 

It is indeed slightly faster than the 2670QM, but keep in mind that the upgrade is from a 2760QM. Thus, the "upgrade" is essentially a trade of an extra 100MHz of clock speed for 2MB of extra cache. It's basically identical, but unless you are using a rare cache-bound application, I don't see the point.

 

I would definitely pass on this 'free' upgrade - they are simply trying to clear their old inventory of processors.

While the less than 2% difference between the cpu's (with the faster one being the i7 2670QM) is not what I would base my decision on; it is the fact that the i7 2820QM is Q1 2011 'tech' while the newer i7 2760QM is Q4 2011.

In your shoes, I would NOT opt for the 'free upgrade' - it is a lesser processor in my eyes.

The 'proof' that I have on recommending this way is this:

The 33% more cache is still not enough (in PM 'scores', at least) to offset the ~4% increase in base clock speed for the 2670QM.

This makes the 2670QM overall more efficient per clock cycle and at the same TDP rating both processors share.

As mentioned; unless your usage scenario specifically requires a larger cache (mostly server type workloads...), then this 'upgrade' is really a downgrade in all ways that are actually important imo.

Always buy the latest hardware - no matter how tempting a nominally higher end, but older model seems - the latest revisions are there for a reason (lower energy consumption, higher ipc, optimized micro-code, etc.).

Instead of taking this 'free' offer - I would ask what else can they offer in it's place - like 16/32GB RAM 'free' instead.

Good luck.

 

Q1 tech, Q3 tech? What? Do you have detailed specs on intel's process tweaks? Are they for power/speed or yield improvements but for slightly lower quality chips?

Considering the margin intel are operating at due to the lack of competition you have no way of knowing.

Just look at the speed and the cache, decide which affects the programs you use more and opt for that one.

 

considering 6MB cache plenty already....
i would go for extra 100MHz...
