I just bought an Asus Laptop with Intel Core i7 2920XM Extreme Series Processor. I just received it yesterday. I installed CPU-Z to recognize the processor, but I received that information from CPU-Z (Intel Core i7 2920XM Extreme (ES) after I started it.

The processor model and the step information like the below.

Family 6
Model A
Step 6
Revision D1

Is it the Engineering Sample or OEM / Retail?

What is the differences between them because Windows 7 rates this processor with 7.4 from 7.9 even it is the fastest processor of the market. Can you give me some idea about that processor? Should I return that laptop for the processor replacement? Thanks

Its far from the fastest processor on the market, the i7 990X and its Xeon counterparts hold that title, and WEI is far from a good way of judging system performance, its scores change as newer faster parts come out so its not a solid benchmark score.

Your laptop will NOT contain an engineering sample CPU, those are in limited supply and are preproduction units that may not perform exactly like the retail units so they are never put in regular machines, your laptop will have an OEM version in it.

Time to get on the phone with whomever you bought it from for some answers. If in fact they did install a ES chip in your laptop by mistake I would return it. I don't think Intel would even warranty that chip and there is no telling how hard that cpu has been hammered in testing!
As far as the WEI rating of 7.4 I don't know what to make of that! You'd think it would rate 7.9 but oh well.
They should pay shipping both ways too!

7.4 WEI is incredibly good for a laptop CPU. Remember, there is a sizable difference between best laptop CPU on the market, and best desktop one. Since my i7 2600K desktop chip gets a 7.6 at stock, I'd say your ranking is pretty dead on, high even

Btw, not even any desktop chip scores a 7.9 (at least on stock speeds)

CPU-Z says it is (ES) I would wish that they could not have installed an (ES) chip, but CPU-Z says it is ES.

Do you have any idea about the below steps and info of processor

The processor model and the step information like the below.

Family 6
Model A
Step 6
Revision D1

How many percent performance difference can have between (ES) and OEM / RETAIL processor?

wrong wrong wrong!!!

read and restate previous post because it is not a sizable difference. the 2920xm beats the 980x in gaming and and very competitive in other areas and beating the 980x in single threaded programs.

also my 2630qm scores a 7.4

I also realized another strange thing on the intel's web site. It says on their web site 2920XM Extreme processor supports up to 8GB memory, but my laptop has 16GB

CBrunnem, beating the 980X in single core apps is absolutely meaningless. So does my i7 2600K, but WEI does not measure single core speed, it measures speed across all available threads. Even the higher end Core i3s will beat a 980x on single core

The i5 2500K desktop CPU gets about a 7.5 on WEI. The 2920XM, while an excellent processor, is not as good as the i5 2500K all around

Either way, WEI is a crappy benchmark anyways, and less reliable than many others. Download CPUZ and check the specifics of the CPU, see if it says ES. Run some valid benchmarks on it like Cinebench 11.5, SiSandra, or 3DMark

Tomshardware has a test at the below link for that processor versus to i7 980x

They used 1.56 version of CPU-Z. It says the below information for the processor.

Intel Core i7 2920XM CPU @ 2.50 (does not have any info as ES like mine has)
Model A Step 7
Revision D2

Which is the above model of my processor (it looks like)

If someone knocked on your door and told you to run because aliens were coming, would you grab your stuff and run or assume they are crazy?

Dumb analogy, but the point behind it is to look at the situation logically. It's much much much (I could keep going) more likely that CPU-Z is reporting incorrectly than it is that you got an engineering sample CPU. Don't worry about it, and if you must, try a few different programs to check what it's telling you.

I have used another program to watch its temperature, but it shows it is ES series too. the tool version is CORE TEMP 0.99.8

how is beating the 980x in half the games meaningless? thats damn impressive for a laptop cpu.

not quite sure what you point is but the 2920xm is a competitive gaming cpu to any cpu out there. it might not be the most cost effective but it is still very strong and i dont care how it does it because facts are facts.

Also I did not open that topic to discuss the performance difference between 980x ans 2920xm. I opened it to learn differences between 2920XM (OEM / TRAY / RETAIL) and Engineering Sample (ES)

Also confirm if my processor is ES or NOT

Its a great cpu however we are talking about an extreme version of Sandy Bridge architecture.Wait later in the year for 2011 socket then we can see the extreme version of desktop computing.
Not sure when it will come out probably this year probably next but we might see the extreme version some time later.
Gud day to you sir.

It deserves a huge amount of credit - I've long maintained that mobile is where Sandy truly shines. Mobile sandy bridge impresses the heck out of me, and I am amazed every time I see it tested.

That having been said, that test really doesn't show a whole lot. Crysis definitely does not use more than a couple of threads, and a 5% difference at low resolutions in a laptop doesn't really tell you anything useful about true performance.

I think I found an information regarding the processor. The current and the actual stepping and revision information like the below

Model A
Stepping 7
Revision D2

It is looks like one model higher than my version.
