I'm just curious, is there a PC really has achieved 7.9 for the CPU (Windows 7 Experience Index)? What are the specs?

Note: I also know that the WEI score can be hacked, so do not try here. Also, please do not discuss "My score is only 7.8" (too many people who have it).

I don't think so. Based on some of discussions on the internet (you can googling it), even EVGA Classified SR-2 with 12-core Intel Xeon only reached 7.8 (just like the i7-2600K).
 
Throwing my .02 cents in....

^---Quite a few of these numbers appear to be bunk found here.

From what I understand, I believe you would need a very good combination of low timing ram, a healthy OC and a good reliable chipset.

Basically you would have to set everything optimally manually to get 7.9

As everyone else stated though, WEI is not the greatest performance analysing tool. It's good for a basic rundown to make sure certain components are running as they should.

When the processor tests are running, all 8 threads of my 2700k appear to be utilised, suggesting more cores yield higher scores. Mine's clocked to about 4.9 and gets 7.8, so assume it must be possible to get 7.9 with a hex core. Don't have one so can't confirm.

But it's of theoretical interest only - there are many better benchmarks out there.

Having said that, I don't know if I'm unique in this but I still run CPU mark99. Terrible benchmark and only single threaded but has the advantage that it was available in 1999 and I roughly remember the scores for every processor I've had.

Pentium 200MMX - 12
AMD K6 III - 50
Duron 850 - 85
Athlon 1800 (Palomino) - 130
Athlon 64 3700 - 270
Core 2 Duo E8400 - 400
Core i7 920 620 (When O/C to 4GHz, 430 otherwise)
Core i7 2700k 780 (OC to 4.9GHz)

Of academic interest only, but it shows a 65 fold increase in one particular measure of single threaded integer performance over 13 years, which is quite interesting.
 


Interesting. What would be the difference if you factored in size and core count as well? Those old CPU's are massive by today's standards.

What hardware do you need to reach 7.9?
Components may vary by manufacturer, and having specific hardware may not guarantee a 7.9. But people who have built high-scoring PCs generally have bought the following pieces:

> A quad-core desktop processor with at least 4 gigahertz (GHz) (with a water cooling kit for overclocking) or a six-core processor
I doubt this, even I've heard that i7-2600K OC @ 4.80 GHz and i7-990X @ 3.46 GHz (stock) they still only get score 7.8.


> A socket 1366 motherboard
It's irrelevant.


> A low-voltage desktop memory system with 12 GB of RAM
It's very possible true.


> A GTX 285 graphics card
It's very possible true. One thing I know, that GTX 580 would reach 7.9 (for Aero and Gaming).


> A 256 GB internal solid-state drive in a striped RAID 0 configuration
It's very possible true. Or simply install a 240 GB SandForce SSD (SATA 6 Gb/s).


> A 1000-watt power supply
It's irrelevant.
 


A 4.5GHz 2500K (mine) does not have a 7.9. Nor did a dual 6 core LGA1366 system I setup for a customer a while ago, and thats in essence 12 cores/24 threads.

Besides, my Q6600 @ 3GHz had 7.3 WEI and my 2500K @ 4.5GHz moves up .5 to 7.8? Doesn't sound like WEI is useful at all.

For a while my HD5870 has a 6.3 WEI. Not sure why. Reinstalled 7 and it went to 7.8, pretty much everything is a 7.8.

I am guessing it will take a quad CPU system to get that extra .1 score.

There are several theories (not yet proven) about how to achieve score 7.9 for the CPU:

01. Overclock 6-core CPU (e.g. Sandy Bridge-E) or 8-core CPU (e.g. Zambezi) until very extreme frequency (almost 6.0 GHz).

02. Using 16-core two-socket processors (e.g. Intel Xeon E5-2690 + EVGA Classified SR-X), with corespeed @ 3.80 GHz.

03. Install Windows 8 Beta or Developer Preview (somewhat ridiculous). :pt1cable:
 


1. I still doubt it, see 2

2. Built a dual socket 6 core (two 6 core/12 thread Xeons for 24 threads) system with that mobo, still only got a 7.8 on WEI.

3. Possibly but it will probably have up to a 9.9 just to troll people who really care about the top WEI score.

Maybe the dual socket LGA 2011 I build in the near future will hit it. I will let you guys know.

Thank you, if you could please suggest that WEI scores (Windows 7 and Windows 8) listed in the review of dual-socket CPU (if available).
 
when you go Win 8 and see that the WEI score is now raised to 10...
i5-2500K @ 4.5GHz

http://i1130.photobucket.com/albums/m529/malmental/1-1.png

I so guessed right on the WEI score going higher.

Still, it gets 7.8 (my 2500K @ 4.5GHz) in 7 but 8.0 in Windows 8? That seems.... off.



We will probably get the parts within the next week or so and I will start the builds (they want 4 of them..... should be fun) and I will keep this thread in mind when I do it.



Still seems strange since I would assume that 12 cores/24 threads even clocked lower would have higher overall thoroghput than 4 cores/8 threads OCed.

Still its a strange system they have. It makes no sense. As I said before, my HD5870 had a 7.8 then dropped to a 6.3 and when I upgraded my mobob, CPU and RAM it went to 7.8 again.

My 2600k at STOCK gets 7.8 (the one in my sig) but when I oc'ed it after getting my new waterblock on it to 4.6 it's still 7.8. Don't know why people would care about WEI anyway though, lol. My dual 560 ti's get a 7.9 on gaming and aero though.

It's very interesting, I'm very curious whether two Intel Xeon E5-2690 is able reach perfect score 9.9 without OC (on Windows 8).
 
I've never seen a legitimate WEI of 7.9, even my 6-core SB-E i7-3930K @ 4.8GHz is 7.8. I've seen it reported by those with the 8-core E5-26XX running the assessment WEI has a bug.

About the only 'good' reason to run WEI is that it detects if you have an SSD and disables Disk Defragmenter from defragging your SSD. /edit - I too have had OP's post really low scores to help diagnose a major problem.

Yeah it's a lousy "benchmark" for sure. I have the same cpu at 4.7GHz and CL9 ram at around 1650Mhz scoring 7.8 for the cpu performance.

I noticed with my FX-8150 platform that having a faster RAM also increases your CPU score way more than the real life experience in WEI (from 7.7 with 1333MHz to 7.8 with 1600MHz). With my Sandy E I noticed it doesn't really matter if you run the test with 4.5Ghz + or at stock speed. Same score. It doesn't even seem to utilize 100% any of the cores during the CPU stress test.... so.... :p
