Nice review De! And of course, you are correct there also.
I was not referring to the L2 cache found on MANY fairly modern prcessors though. Your bottlenesck will not be the L2 cache or the smart cache. The "potential" slowest point of data throughput flow will be the Random Access Memory also known as RAM. It also comes in various speeds as well as AMOUNT.
Think of it as the opening GATE on a large DAM. When you open that gate you allow water to pour through.

The larger the opening, the more water, or data can pass through unobstructed or hindered.

Thatis only reason why mentioned about getting 32 GB's of RAM instead of 16 IF you wanted a truly monster data throughput machine.

ALSO, when you get that machine, check the CPU at "normal setting" and see what the normal speed really is.

From all I read, I am betting 2.8 Ghz with 3.8 Ghz being top speed on Turbo setting.

I found ZERO of that model number of INtel Mobile pricessors with a base speed of 3.8. IN order to obtain that speed one must set the cpu at Turbo boost setting in the cmos settings.

I think the machine you are getting has already been set to turbo so it is going to be at the 3.8 lvel you want .

The only important thing in all of this technical dicusion is that YOU like the way it performs and whether it accomplishes the needs that you have for it to accomplish. Everything else is moot but makes for fun discussion.
I haven't had this much fun since retiring from the computer advice board...

Hope you get it soon!

Re: "I would take the memory over the raw speed of the cpu every day of the year..."Right you are.

I'm sure you know, though, that there are several kinds of memory in a typical computer. They operate at different speeds and come at dramatically different prices. The 16 gigs of RAM that you discussed are very important to the computer's overall speed, but they're also the slowest and cheapest of the three types in the laptop. The Level 2 cache on the motherboard is far faster, and the Level 1 smartcache on the processor is SO much faster and costlier that the manufacturer gives this laptop with 16 gigabytes of RAM just 8 megabytes of smartcache memory. To put it another way, the computer has two thousand times as much RAM as smartcache.

My beef with Amazon is that I ordered a machine with 8 megs of smartcache and they delivered one with just 6 megs of smartcache. That was a $190 mistake... in their favor, of course... as Intel currently sells the i7-4900MQ CPU for $570.00 and the i7-4810MQ CPU for a relatively modest $380.00. (Kind of funny, when you think about it, that the i7-4900MQ CPU sells for more than I'm paying for a laptop containing one.)

But it's not about the money. It's about the fact that I paid for something that will give me a certain level of performance, performance I think I will require in order to terraform my own Minecraft world, and Amazon delivered one that is substantially inferior.

I returned the "bad" laptop today and re-ordered. The new Dell Precision m4800 should be here on Tuesday. You can bet that the first thing I'll be doing is checking to see if it has the right CPU. The second thing, probably, is writing a review on Amazon warning people who order refurbished equipment to verify that what they received is, in fact, what they ordered. If this "mistake" was done on a large scale, it would be quite a scam. I don't think many laptop purchasers would ever notice it.
