The e8600 is Slower than e8500

I have been using 2 computers in which one is laptop and the other one is desktop. The Desktop PC contains Intel Core 2 Duo e8600 processor and the Laptop contains e8500 processor of same. When I ran the 3D mark vantage program to check clock for clock score for both computers’ CPU and GPU, I got different result. What I got is the e8600 scores less than e8500. The difference between the cores was actually 400 with same BIOS settings. When looked into the Desktop which also has e8500 I got the same result. I couldn’t able to find the reason for it. I think that maybe I am missing something. There was also a variation in GPU scores. The superPi time also seems to be a bit slower. Can you describe it? What would be the reason?

Are your processors containing same GHz? If you use different clock speed processor then of course you will get a slight variation in scores. But not much as you think. But it will not going to decrease any performance. The reason behind lacking in scores is because of some incompatibility issue of Hardware or components. Did you use the same configuration? The chipset drivers, windows version and its update, BIOS version and also some other component drivers will affect the score. You don’t need to worry about it. Only the scores seem to be lower not the capacity of the whole processor. It will perform as it was created for. The different version processors vary in some Core.

As far as I know clock for clock, the E8600 processor is slower because of some variation in the version of OS. You should know that E8500 has a FSB of 473.68 MHz. On the other way the E8600 is 450 MHz. This describes that the equipped frequency at the identical clocks is efficiently superior on the lesser multi. One thing you should know that E8600 has the capability to attain advanced clocks. That means it will really going to beat other processor. So don’t care about the scores you got. Just see how you will get the output from it.

It seems to me that something is missing in your system configuration. Do you have the same configuration in both? Check that the both contain same RAM. Update the latest version of drivers for all components and chipsets. Update the OS and also the BIOS. If still getting same result. Re-assemble and reinstall both computers and see can you reach the value without installing any third party applications. Also try the cpu-based bench like Super-Pi for each processor. This program will give you the real result. You can also use other CPU based programs to test.

All I know is it's not slower clock for clock. I have seen and used those processor and what I get is when I run the 3D bench, every time i got different numbers. Whether you use same setting or same computer, you will get different scores for every run. It is not the issue of either the processor or the program. It’s just the behavior of the program to get true result. Even after rebooting also you will get different numbers. So it is not possible to say that e8600 is slower than e500.

Are they working at the same settings, mean same MHz speed? Do their multiplier locked? If the multiplier has been locked, still at equal MHz on the whole OC, the lowly multiplier will run at a elevated FSB, and then the CPU sequences are actually, further more effectual, for the reason of a divergence on bandwidth accessible to the core. It would be something like evaluate two 400 MHz CPUs, one at 1x400 FSB and other at 2x200FSB. At this point the second 2x200FSB would undergo from memory boundaries on the memory controller supplementary than the 1x400.You should know that not all the CPU cycles are useful. Some may lost in waiting for the data. So it's in reality promising that you wrecked up with slower system, clock per clock
