Before we say anything else, let's just point out the fact that the WinBook J4 running at 2.4GHz is the fastest mobile system in 2D we have seen to date. The J4 outperformed our previous 2D king, the Compaq Presario 2800T 1.7GHz by a little over 12% making for quite a nice speed improvement. You can thank the 2.4GHz processor for the speed that the WinBook J4 has.

Now, let's take a look at how the J4 compares to our desktop solutions. First off, let's look at the desktop 2.4GHz SDR platform. This system should be relatively similar to the WinBook J4's configuration and it is. The desktop 2.4GHz SDR system performs only 9% faster than the J4. The performance advantage offered by the desktop can be attributed to the faster hard drive used in the desktop test system. We have proven time and time again that notebook hard drives are just not up to speed when it comes to application performance.

Things become interesting when an 845 DDR board is thrown into the equation. We decided to see exactly how much the J4 was being penalized by using an SDR only solution. To test this we configured a desktop system based off the Intel 845 DDR chipset and put in the same 2.4GHz processor. We found that the DDR solution on the desktop platform performed 16% faster than the SDR solution. Using this information we can estimate the performance boost that the J4 would have had using a DDR memory bus to be a little below 16%. This gives you an idea of exactly how much the J4 is being held back in its current SDR memory bus configuration. It is likely that switching to DDR memory would put the J4 ahead of the competition by almost 30% as opposed to the 9% speed advantage it currently has.

We see the trend described above carry over to the overall SYSMark 2002 score. The WinBook J4 outperformed its closest competitor by 17% but it had the potential to do much more if only WinBook opted to use a DDR memory bus.
