Old notebook higher performance index than new notebook

Hi,

I just bought a new notebook and it´s Windows Vista performance index for RAM is lower than on my old notebook, while both use the exact same type memory yet the old notebook only has 2GB while the new one has 4GB.

On my new notebook the performance index for RAM is 4,5, while on my old notebook it´s 5,9. Not a very small difference. Below the CPU-Z information for both notebooks. Doesn't anybody have any idea why the index is higher on my old notebook? Overal, the performance index is higher on my new notebook (4,5 versus 3,1), yet for RAM it's lower. Thanks for your replies!

All newer AMD cpus get a 5.9 in memory performance due to Hypertransport. I wouldn't worry about it, seeing as WEI is a pretty much useless benchmark. Your new laptop is faster.

 

I agree.

If you'd like to do some memory benchmarks try the ones in PC Mark / Vantage.

 

WEI can be seriously misleading at times.

It came up with a memory score of 4.5 for the Zepto Notus which has 1GB of 400MHz RAM.

Another program which includes a memory benchmark test is SiSoftware Sandra.

Another example of the innacuracy of WEI, me and my father have the same exact memory. Same brand, speed and size. I get a 4.9, he gets something around 4.2 or something.

Use 3DMark and/or PCMark for benchmarking.

 

the Windows test is complete BS, so dont pay any attention to it.

fabarati has it correct, the amd processor will always have faster memory bandwidth because AMD processors have integrated memory controllers built into the processor, whereas the Intel processors do not have a memory controller and must reside in a much slower chipset, thus bottlenecking the system and making teh memory run slower. If you run a real benchmark like SISandra, you will see that the memory bandwidth on your older system will be much higher because of this. However you should not worry too much since the speed of the memory really doesnt impact the speed at which your system runs.

My T7300 has scored higher than my dad's T7700 almost all the time.
