I built a new PC in July/August around the AMD FX8350 CPU; Asus AMD 7870HD GPU; Asus M5A99FX Pro R2.0 Mobo; Corsair Bronze CX750M PSU; 3 Toshiba SATA 1 TB each HDD; I OCZ 256 GB SSD; 16 GB PNY 1333 DDR3 memory; Windows 7 64 Bit.My WEI scores were 7.8, 7.8 on the CPU and memory scores and 7.9, 7.9 on the GPU scores with 7.8 on the storage scores. I don't know why my CPU scores were not 7.9 for the 8350, But I was okay with 7.8. I suspect the lower quality 1333 MHZ PNY memroy from my prior PC kept the score down. And I planened to upgrade to 32 GB 1866 MHZ eventually.Initially the Windows Experience Index reported the FX 8350 correctly as an 8 core processor. But after several Win 7 OS updates and the Final BIOS update it now reports the FX 8350 as a 4 core processor. It always reported my GPU incorrectly as DX 10 instead of DX 11.1. But that is for another thread. My BIOS reports the 8350 accurately as 8 cores. WIndows Device Manager also reports it accurately as 8 cores. And DXDIAG reports the GPU accurately as DX11.1.So my question is this. What is the reason for the disconnected reporting in WEI if anyone else has experienced the same problems. And how did you fix it. Is this something to worry about? Or is WEI just fundamentally inaccurate? Because all other BIOS generated stress tests reveal correct CPU information. Is the FX 8350 a true 8 core processor? OR is it 4 core with 4 virtual cores?

The following reference explains it all...

[Discussion] AMD's "Module" Architecture: The FX 8350 is not a Quad-Core.
http://www.reddit.com/r/buildapc/comments/1e8226/discussion_amds_module_architecture_the_fx_8350/

The FX-8350 has four modules. The module contains two “traditional” integer cores, each with its own scheduler and L1 data cache. This is partly where AMD gets away with calling their 8350 an 8-core CPU. A module has two 128-bit FPUs that can be paired to carry out 256-bit instructions. Each modern Intel CPU core has its own 256-bit wide FPU. A module is recognized as two logical cores by the operating system.

Modules are not like Hyperthreading. These modules are not dual-threaded cores, they are CPU building blocks that have two cores inside them. Hyperthreading works by taking the resources of a single core and running two threads through it, and each thread takes a significant hit to performance compared to if they were executed on separate cores.

In a patch released for Windows 7 and by default in Windows 8, Windows recognizes Bulldozer-based CPUs as 4-core/8-thread CPUs. This has to do with how the operating schedules tasks on the CPU.

Mine...CPU at 4.8GHz, GPU's at stock.  The magic 7.9 is unattainable....no worries, I can't even hit it at my CPU's max clock of 5.25GHz with 6 cores and 12 threads.

Thanks MrEd. Is there a work around to fix this interpretation. Because the WEI reported the FX8350 correctly as 8 core before that patch update. I also noticed that your score sheet along with others below had the same DirectX version error as mine DX 10. Is this happening as part of the same process? Why can't WEI even accurately read/record a DX11 GPU? Perhaps Black Zion is correct. The WIndows Performance Index scores are worthless.

There has always been a lot of confusion about mulit-core CPUs. AMD's 8-core CPUs most definitely ARE 8-cores. They use a quantity of four DUAL cores to achieve the 8-cores. Those who are technically challenged do not understand that 4x dual cores = 8-cores.

For the record Intel CPUs are often show as half the "advertised cores" because they use hyper threading which is a virtual core, not a physical core like AMD uses. So in Intel's case they really do have half the advertised cores, where as AMD really has all of the advertised cores as physical cores.

Many PC benches and system hardware reporting programs compensate for Intel CPUs as Intel has ~80% of the PC market. AMD is often ignored or improperly reported because they are the small guys.

Technical ignorance is NOT a destiny it is a choice. Do your homework so that you can make technically informed decisions and not be duped by advertising hype or mis-information stated as fact when its not.

One day maybe AMD will design the modules so that users can select ganged or unganged mode for the integer cores.

While it may happen I doubt that it's a high priority for most PC users.

MrEdoes this mean Windows 7 locks down the logical cores. Because that is my concern with the report. If it only schedules 4 cores, Won't that limit the Capability of an 8350 based PC to handle ports from NexGeneration consoles?  The Next Gen consoles are are 8 core designs. And I still don't understand why the WEI is reporting my GPU as DX 10. Even though it is reported as DX11 in their own DXDIAG tool. If the WEI is not an accurate reference of anything happening in my PC, then none of this matters. But if Windows is somehow limiting the capability of the system, or I need to hotfix something in the registry; that is a big deal.

The problem with WEI is caused by a limitation of these tools in Windows 7. The latest version of DirectX that these tools can report is DirectX 10. This limitation does not affect the hardware functionality or the software functionality of the graphics adapter.

Thanks WMudrockJr That is exactly the information I needed. I presume the misreporting of the cores is the same thing. ANd no system limitation is being enforced for games or console ports that require the 8 core architecture.
