    I have a Lenovo Desktop which has an Intel Xeon CPU E3 3.30 Ghz with 4 GIG RAM, running Windows 10 PRO 32 BIt

    I have just bought another Desktop for graphics work etc.

    It is a Dell Optiplex 9020 which has an Intel I7 4790 CPU 3.60 Ghz 8 GIG RAM running Windows 10 PRO 64 Bit.
    I think both are quad core. It also has a 2 GIG Radeon video card.

    I put identical SSD 250 GIG drives in both, which have tested at similar speeds, and although are not the quickest both pass all the tests. Both PCs boot quickly.

    As the Dell I7 appears to be a much higher spec, I was expecting a much better performance. I have been using AUDACITY audio program to chop audio book MP3s into smaller chunks, as the books were just in one file. Audacity does all this perfectly, but the Lenovo I3 is much faster at loading the file, and then exporting the output, both to an SSD drive.

    As I have said many times before, I get lost with a lot of the technical stuff on here. Please answer the following:

    Is there a simple performance test than will run on both 32 and 64 bit Windows?. I would really like something like a score out of ten, that would simply show the quicker machine.

    Am I wrong in expecting the I7 to be much quicker, as the SSD drives show identical performance?

    Both machines are running perfectly, and the extensive DELL diagnostics report no errors.
    Many thanks

    When comparing 2 CPUs you'll need software that uitilizes them at the max. In single-thread (even if 2 cores are used) applications they might be equal. A good test is install.wim to install.esd conversion which should be much faster on the i7 since it uses all available cores and is a good stability test though.

    Thanks again, just a couple of questions. Any chance of how to install, and where do I get the file. I tried RUN but not found. Google mentions WIN8, but what do I use for WIN 10. The install commands for ESD would be very helpful. Is this just a test, or a permanent improvement for these type of programs.

    Many thanks.

    It's a compression task, nothing to install. An install.wim is main part of a Windows ISO and contains the Windows files. Process is used in the ESD>>ISO and UUP>>ISO converters by @abbodi1406 .

    In your case i recommend to check for CPU benchmarks like Cinebench and run the multi-thread part on both systems, you should see the difference.

    Have u check what kind of ram u running, dell proprietary factory memory is slow, u mite want to swap it out for faster one.

    Not sure exactly how to answer your question. What program do you use?

    The score of 7.9 Dell to 5.5 Lenovo, must mean that the DELL is quicker?

    Hello again @ loatpassword - Could you tell me the specific model for the Xeon E3 used in the Lenovo? Is 3.3 Ghz the base processor speed or is it the max turbo speed? I'm asking because I visited the Intel Ark website and found two different processors listed. The E3-1260L has a base speed of 2.4GHz and a max turbo speed of 3.3 GHz, while the E3-1240 has a base speed of 3.3 GHz and a max turbo speed of 3.7 GHz. If you have the latter, it's very close to the i7-4790 in terms of processor speed.

    Also, WindowsGeek touched upon a very good point, how does the speed of the memory and the speed of the front side bus compare between the Lenovo and the Dell? Even though the Lenovo has half the memory of the Dell, keep in mind the Dell is running a 64 bit instruction set vs. 32 bit for the Lenovo, and if the Lenovo has a faster front side bus along with faster memory, that could explain a lot.

    Interesting points you are raising - Windows System Info shows for LENOVO
    Intel(R) Xeon(R) CPU E3-1226 v3 @ 3.30GHz, 3301 Mhz, 4 Core(s), 4 Logical Processor(s)
    DELL
    Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz, 3601 Mhz, 4 Core(s), 8 Logical Processor(s)

    You have lost me a bit on the bus issue. But I have now run a video convert using XILISOFT Video Converter Ultimate. I paid for this, so can convert any length. This is a slower converter than many, but gives a good result. For a 552 MEG MP4 file to AVI the LENOVO TOOK 16mins 20 sec and the DELL was faster at 14 mins 21 secs (the prog has a nice timer), also shows CPU usage which was around 55% on LENOVO and 35% on DELL. The DELL was about 14% quicker on this job. A weird result was the LENOVO showed file size of 866 meg and the identical file on DELL ended up as 879 meg. Both files play with fantastic quality and sound. Must be related to different video hardware ??

    OK, I wasn't trying to talk you into buying new DIMMs for either machine. I just wanted you to see if what Crucial recommends using is different from what you have installed on either machine. Just trying to confirm if WindowsGeek's theory concerning Dell's use of low spec RAM might be valid.

    Thanks - the Crucial Scan shows only 2GB DDR3L-1600 UDIMM unbuffered NON-ECC.

    There are 2 empty slots, looks like 4GB is out of stock. Not sure if this is any help. Crucial reports Standard memory installed.

    Windows reports that the existing RAM is 8GB DDR speed 1600 Mhz DIMM . Don't think this is helpful enough to compare speeds, but not sure?

    Just for interest the DELL seems very well built, and weighs about 3 times some of the cheaper desktops. Everything inside the case is accessible etc.
