Passmark numbers -- are they useful?

Every so often a question is asked about PC performance and the Passmark numbers.   Are the Passmark numbers meaningful and helpful?   I started collecting passmark data about 18 months ago to see how it relates to SSDR user experience.    I think the Passmark tools can be helpful in ruling out your PC as an issue and also a good way to measure the impact of the upgrades you make.  So FWIW, here is a copy of my latest update based on recent user feedback.   The good news is that it doesn't require a "fire breathing" PC to run SSDR. 

 
The Passmark score and how it relates to running SSDR. 

Al / NN4ZZ -- 18-Jan-2015 -- updated notes based on user feedback

Some Flex users have reported issues with performance when running SSDR software.   The symptoms are slow response, jerky screen displays, disconnects, etc.  There are a number of potential reasons.  

-          Network or connectivity issues. 

-          Software, or driver issues.   Malware.

-          Inadequate PC performance

 

Passmark can help rule out your PCs performance as a factor.  It can also be used to measure the impact of improvements.    Based on the data collected, some Passmark performance metrics are more important as it relates to running SSDR and others are not.    For example:

More Important -- 2D graphics score, Overall score, CPU score

Not as important – 3D graphics score and disk drive performance (although these do factor into the overall score)

The Passmark values here were compiled based on member feedback.  The suggested numbers are based on SSDR running concurrently with other programs (browsers, email, loggers, fldigi, ddutil, etc).    The data provided by the majority of members meet or exceed these numbers.    

 

A Free 30 day trial of the Passmark tool is available to test your PC.

Notes & Caveats:

- Higher numbers are better, but these values below appear to be adequate with some headroom

- you may find that adding a good video card is all that is needed to bring your numbers up on an older PC.

- The recommendation does not take the network connection into consideration.  A connection of 100 MB seems to be more than adequate.  Wifi appears to be sufficient although some latency issues have been reported.   This could change when the LAN remote and WAN remote versions are released

- The 3D graphics metric doesn’t have an effect on SSDR performance for the current design of the software but that may change some day.

- If you are running SSDR on a Mac in a virtual environment you may not get the 2D graphics performance as reported by Passmark. 

- your mileage may vary based on how you use SSDR, other types of programs your run that may require more resource, your memory and disk setup, number of monitors, etc.  If you have additional input on the Passmark numbers please post your results and comments to the forum.  The numbers will be adjusted as needed.

Hi Al,

Thanks for posting this data, (with a caveat)....   Checked my ATI Radeon HD 2600 Pro and it hit 273 on the 2D score.  I could tell the GPU was struggling a bit so I think your cutoff at 300 is on the mark. My CPU score is 2400 on an old intel core2 Quad @ 2.4Ghz.  

The machine doesn't seem that old but technology sure marches on fast.  The Smartphone chips I work with are much faster than this puppy.  Obviously would be nice it SSDR was on Android but that's a whole other topic.

Caveat - Time to upgrade the GPU unfortunately....


Best Regards,

Al,

I am running a 6700 with a home-built Core i7-920 + NVIDIA GeForce GT640 + 12 GB + 1000bT networking. The passmarks (thanks for the link!) are as follow

Overall = 1838
CPU = 5227
2D Graphics = 554

These seem well above your suggested figures for the 6700.

I find this is not enough if you want flawless operations with 8 panadapters running full out.  It will run without glitches up to about 5 panadapters.  (I find it hard to imagine using all 8 this way, but I think it's supposed to work!)

I do look at GPUShark and Task Manager and see that my GT640 runs < 21% and CPU runs around 52% when showing 8 panadapters.  To me, this suggests that there are other problems, like a software threading bottleneck -- to take a WAG.  (Maybe SSDR just won't use more than 4 hyperthreads?)

So I wonder if anyone can point to any computer configuration that does support 8 panadapters, full out, without glitches?  Is this one of the many things that should be improved in SSDR 1.4?

Hi Martin,
Thanks for the data.  Your Passmark results would suggest that your PC is plenty for the 6700.  So perhaps there is another problem such as a video driver, etc.   There have been reports of performance issues in V1.38 so it will be interesting to see if the new version V1.4 coming in a few weeks resolves it.

Let me know if you find that V1.4 helps or if you discover something else.  

I rarely run more than 3 panadapters so it will also be interesting to hear for anyone that uses all 8 (or even 6 or 7) on a regular basis.   

Update --- I almost forgot to ask what version of Windows are you running?

I have Windows 7 up to date, directX 10, etc. There are different NVIDIA drivers to consider. Does anyone have info on that question? I think I have the latest.

Recommendation:
Try the current nvidia release first and see how it behaves, if that works your done. If it's a problem try the previous release. Rinse and repeat as often as you have too. Be sure and uninstall any version thats installed before installing a different one. Nvidia drivers are such a moving target that there's just to many variables to know what will work.
Sorry I know thats the exact answer you didn't want. The actual recommendation is use the latest release available that works. Even less helpful I'm sure.

My NVIDIA driver version was 344.60.  I tried 340.52 with essentially the same results.
