It is lovely to have such a feature in windows 7

Performance scores can vary so much in eveery category. No info on how they measure the score precisely

SO, I 'd rather like to share performance score here with you

What do u think?

[nitroshift]

It was there in Vista too, but the max score was 5.9 as opposite to 7.9 in 7.

[medhunter]

oh , I see. I kinda skipped Vista . ran from XP to 7 .

Yet I haven't known ur score yet

Please Share Your score. with this rig(in your sig.) I expect a rather high score

[Social-Zero]

on my Dell XPS M1710 Notebook I get a 4.5 score.

6.9 on graphics which is the highest score I get

and 4.5 on my processor which is the lowest.

Running Windows 7 beta 1 build 7000 and the notebook has 4GB of ram and a Nvidia Geforce 7900 GTX 512MB

The processor's only 2.0 though, I guess that's doing it

I'm running 7 on a crappy laptop (1.73 Celeron / 1GB RAM / onboard SiS 3D grahpics) and got 2.9 On the rig in my signature I'm running Vista Business x64 with a 5.9 score

The rating system is not working correct on Win 7

New Computer
My Quad Core at 2.5 and 8 GB Ram it gets a 2 on Win 7

Old Computer
My Single Core P4 at 2.5 and 2 GB Ram it gets a 3.4 Win 7

If it's your hard drive score, you can go to the "policies" tab of it's device properties and disable the write back caching, it will result in a much higher HDD winsat score. Vista's winsat didn't take into account the write-flush policy, and Win7's winsat does. Hence, certain drives that perform poorly on the write-flush portion of the test will score (very) low compared to their score in Vista.

Show us the whole break-out and it'll make more sense. For example, this old Dell of Mine running Win7 scores as follows:



Note that under Vista this machine scored higher in every category - memory and HDD, for instance, both got a 5.9, but now they do not with the winsat changes.

Good to know, I was wondering why I only got 3.5 while on Vista 5.9 .

[gunsmokingman]

cluberti I did what you suggested and it improved the disk score from 2 to 3.

[cluberti]

Correct - you will still likely have a "slow" disk (especially if you score 2.0 or under on the initial test), but it will perform "better" - 3.0 will be fine for everyday use, but will be slow if you hit the disk hard.

[Smiley89]

Actually my Hard Disk is the one which got the lowest score - 3.0. I didn't understand why in Vista scored 5.5, but now that I read it's OK.

But I can't complain, since I got a very good general score.



I have a ATI Radeon X1950 Pro and I got this score. A friend of mine has an X1950 XTX and the score is 0.1 lower in poth GPU scores. How is this possible? Both the cards are 512 MB, not overclocked, and my friend has a more powerful PC (not only the GPU). Is something related to monitor resolution? I have a 1280x1024 monitor, he has a 1600x1050 one.

@cluberti, you're using the default Windows graphic drivers. If you install the latest Catalyst for Vista, the GPU scores better. If you already know this, that's OK.

[cluberti]

Yes, I'm aware, this machine is used to test WDDM drivers from WU, so that's why it's running it. And whilst the catalyst updates from ATI are better, there's nothing wrong with the WU driver either, really.

[Smiley89]

Ok, now I understand

Do you have any ideas about the graphic cards' scores I described in my previous post?

Resolution will affect it, as will system bus throughput and bandwidth capabilities to/from the graphics card.

a question about the write back cache;

On my laptop it increased the Performance Score on the harddisk from 2 in a 5.

But in real life; does it increase harddisk performance?
In other words; why did they put in the write back cache when it is decreasing performance?

Yes, when it works it does, quite a bit. What happens is that the drive tells the OS driver that the write is completed once the entire file copy is either on disk or in cache, rather than ENTIRELY written to the disk - it will go back and flush the cache to the disk at a later point when it thinks the drive is idle and won't affect performance. This can drastically improve HDD utilization and performance, and make the system more responsive and hopefully faster. When it doesn't work, however, it can cause the system to be slower, so this was tested for in Win7's winsat because it does matter.

What winsat is testing is the actual performance of the drive during load whilst write-back caching is enabled, and what the score is saying is that, in fact, the drive you have performs FAR better with write-back caching disabled. The reasons for this could simply be that the spindle(s) is/are too slow, or a poor hard disk controller on the system board, or the algorithm for write-back in the HDD firmware is not optimal, etc. A lot of times it's that the hard disk controller does a poor job of handling out-of-order flushes, or that it's actually slow to write (but not read) thus negating any benefit a write-back cache would give, etc. Note that this phenomenon is seen more often on laptop drives/chipsets and older desktop IDE/PATA drives rather than newer drives and chipsets, so keep that in mind.

But, this is much more a "real world" test than Vista's was, so the number is more accurate with the write-back test - your drive really is performing that much better under a "real-world" test with the caching disabled.

[XP_NO]

Thanks for your clear explanation Cluberti.

I defenately will keep the write back cache disabled then

So, then the performance of my laptop tested by the Win7 Performance Score: 4.5

Memory is the issue here....

[cluberti]

Also note that there is a very good blog post on the E7 blog about the WEI changes, and it does go into detail about the HDD test changes. A good read overall.

[Smiley89]

Thanks for the answer about the graphic card.
