Dedicated PhysX Card Experiment - How Powerful Does it Have to Be? Linus Tech Tips - Page 3

post #21 of 82
Well, if anybody cares to know, I have a thread in my sig to show benchies on how systems with Physx cards compare to ones with none.

Yes.

Proving 'established fact' is not bringing much to the table. I was hoping for new information being brought forth.

Two data points are important:- the card with which the curve starts to level off and the 'minimum card'.

This video review does not shed new light to either one of these 2 points.

One one hand, powerful cards like GTX560Ti (384 shaders) and most certainly GTX580 are simply plain obvious to have well passed the leveling-off point. And, GTX550Ti (192 shaders) is also too new for most people to have a spare one sitting inside a closet collecting dust and waiting to be used a Physx card.
So, to this end, older cards like GTX260 (192 shaders), GTS250 (128 shaders) should be used to match the GTX580.

On the other hand, confirming 8600GTS (32 shaders) to be too slow is not helpful to establish (just a little bit more precise ) on the 'minimum card'. Older cards with 64 shaders (eg 9600GT) and with 96 shaders (eg 8800GTS, 8800GS, 9600GSO, GT240) should be tested.

I have an 8500 GT, a few GTX 260s, and two GTX 570's laying here....
I suppose I could redo these tests for you guys tmmw.. Altho you all know damn well Ill get the same results.

I love linus.
post #25 of 82
It took less then one page for the hardcore bashing I would kill to have his kind of exposure to all of that technology, even if it's not the best review, he's doing what he likes; I can't judge that. I always thought the minimum for PhysX was AT LEAST a GTX 260/GTS 450, but if I ever got one, it would be at least a GTX 560, that would Fold most of the time.

He may not be an expert, but he's having fun and making me jealous

The point of this thread is not to bring new information to the table. The point is to post a video that proves what we have been trying to type in plain text all along. Now we have something to show others when they post a thread asking what card they should use for PhysX, or when they ask why they're getting worse performance when they use a dedicated PhysX card.

Nor is that the intention. The intention is to make it even clearer. Plus, most people prefer to watch a video instead of reading a bunch of text.

The reason why he used the 8600 GTS was to prove the point as clearly as possible by exaggeration.

Yeah, I am saying here that you're missing the point of this thread as well as the point of Linus' video.

All obvious results, I personally would never use a card with < 116sp's.
The absolute lowest would be 96 sp's.

What he needs to test are physX at different lane width, 16x vs 8x vs 4x.
I've done that, threads around here somewhere.

And I would like to see ATI/Physx vs NV/PhsX, I've also got one of those treads around here somewhere.

I remember this, 5870/250 > GTX295 in BMAA, maybe more games.

That's what I've put together from 5 minutes of observing, at least.
What are you talking about digging? It was right at the top. I just scrolled down a little. When the YT'er comments on a comment, it automatically goes to the top.

I'm not jelly of his job at all. I just want the right information as I'm sure anyone else would want. But I'm sure that people would LOVE to do what he does, but it's not my cup of tea.

Also, what's with the name calling? It's unnecessary and just makes you look childish.
Oh wait. My bad. Maybe I should have said "Unboxing & First Look" or his "Unboxing & Reviews". It still doesn't look professional. Go look at other people that make reviews of the products, the same products he does. You will see they actually do their job well. Study their product and present it well with actual correct information.

Name calling? Seriously? I called him a prick because he is. Go look at his comment that I posted earlier. If you don't think that was a douche thing to say, then there is something wrong in your head.
