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.

De

I been doing some research on Intel Mobile processors, in particular the I-7 4900 MQ 3.8Ghz.

Let me direct your attentionto the spec sheet provided easily by BH Photo
http://www.bhphotovideo.com/c/product/985518-REG/intel_bx80647i74900mq_core_i7_4900mq_processor.html/specs

The normal clock speed of this processor is 2.8 Ghz. You can run it in Max turbo speed at 3.8 Ghz.

I cannot find a separate processor with the Core I-7 4900MQ part number that is a base speed of 3.80 Ghz which means it could be boosted (overclocked) to to around 4.6 to 4.8 ghz.

I have overclocked hundreds of CPU's on computers for friends and other people who wanted a faster running processor, including my own.

I just wanted to pass this on to you because I suspect what you are getting is not a stock speed 3.8 Ghz mobile processor, at least by that part number. If it is indeed the same part number, then it is running turbo boost and yes, it will be 3.8 Ghz, but its base speed is 2.8

Just some info you may want to bear in mind. More important than the raw 8 threads (processing threads: 4 cores plus 4 more from hyperthreading) from the quad core processor would be the amount of MEMORY or RAM that allows that data to flow through that CPU. That 16 GB of memory COULD have been 32 GB and running the CPU at normal speed this thing would be even faster with NO bottleneck to hinder data passing through the memory...

Anyway, just something to consider. That is expandable to 32 GB of memory. I would take the memory over the raw speed of the cpu every day of the year...

yer pal,

micro Thumbs Up Very Happy
