Hey all,

I noticed that the Intel i7 chip was different between the Mid 2012 and Early 2013 versions of the i7 chip offered. Is there a difference in speed?

When I looked at the benchmark test (this is where it gets confusing), the mid 2012 model was actually faster than the early 2012 model.

I am sure this is very minor differences...but doesn't anyone have any insight?

Thanks.

You are comparing a top-of-the-line 2012 machine that has 8 MB of L3 cache, against a middle-of-the-line early 2013 machine with only 6 MB of L3 cache.

The 2012 model is superior.

The actual change from 2012 to 2013 was simply to increase the clock speeds by 0.1 GHz across the line, from 2.3, 2.6, and 2.7 to 2.4, 2.7, and 2.8 GHz.

Thanks...looks like a refurb mid 2012 is better than an early 2013 model.

I think to do a better comparisson would have to be the top of the line 2.7 model from 2012 (8MB cache) versus the 2013 2.8 model, which has a 8mb cache as well.

Yes, you should be comparing apples with apples. The BTO 2.8 option available for 2013 also includes 8MB cache. The 2013 refresh had several other improvements over the 2012, including better cooling. Technically the early rMBP 2013 is clearly a better machine than the equivalent rMBP 2012. Dunno about the cMBP. The cost difference is subjective. You probably won't notice the speed or cache difference unless you are doing tons of encoding or rendering.

Thanks for the responses. Was just looking at either getting a refurb mid 2012 15" rMBP 2.7 or the early 2013 models - 2.8.

Thanks,

What is the price you get on each case? If the difference is not that big, the 2013 would be a better value.

Refurb mid 2012 i7 2.7 with 768 SSD is $2700.

I believe the equivalent in early 2013 i7 2.8 is about $3200.

The MSRP of the max out 2012 rMBP (2.7 / 16 / 768GB) was $3900 if not mistaken. I paid $2400 for my mine (Samsung Display / September 2012 built) with Applecare from a private seller through Ebay like 2 months ago, so the refurbished price sounds good. For a $500 difference the 2.8 might be the way to go if they have better internals as said here by others. You could wait for Haswell, but won't get a similar deal (up to 40-50% off retail) for at least 6-12 months after they are launched. If I were you, would buy the 2012 or 2013 version and deep discount prices.

Thanks fskywalker.

I may consider a early 2013 2.8 with reduced SSD size - 512GB, instead of 768.

I know the refurb I has a Samsung display.

Decisions...decisions :p.

Some here dislike the samsung color and clarity. The LG SA2 (which are in rMBPS built since sometime in Jan - Feb time frame) does not seem to have the image retention a few SA1s had experienced. They have been out 4 months now.
