GTX 650 as a Physx card

[Keysplayr]

Question what is your performance like when you are running Physx off the 680 SLI?



The 660ti is a $299 card in canada I think that would be overkill for a dedicated physx card.

I think he meant JUST the 660Ti Rendering the game as well as running PhysX content. 1 card. No secondary card for PhysX.

 

[UNhooked]

Best person to ask would be the OP. He has one.

Not yet, I should have it in a week or so. But like I said that card is going straight to the buy and sell forum or ebay. Not going to open it.

Then let me rephrase that in saying that the OP will never know.

When I was running it without the 650 the game chugged a bit in heavy battles. With the dedicated 650 I'm not experiencing the slowdowns anymore.

 

[DooKey]

Do you see any performance improvement by using the 650 as dedicated as opposed to using the 680 SLI cards?

Yes, as answered above, the game performs better using the dedicated card than it did with just SLI 680's. The thing I like about this 650 is it has a HIGH OC out of the box and I push it an additional 90mhz to get 1300 out of it. It's a small card and fits between my 680s and doesn't block any of the fans for the larger cards.

Well that answers it. Thanks Dookey

 

[Makaveli]

Well that answers it. Thanks Dookey

Agreed just what I wanted to here thank you both.

Heavy scenes in BL2 bring the gtx 690 to a crawl. I never tested with a dedicated physx card separately (3rd gpu, 2nd physical card). There is a couple BL2 threads with some tests I ran.

Basically single/2 player, maybe even 3 are ok, but 4 player with major effects kills it quickly in huge fights. (gtx 690)

So got lucky and got a GT 640 w/ DDR5 1GB mem off the classifieds. Will update once I have it. Best part is the card runs off the PCI Express bus, no need for power connectors and it has DDR5 mem to boot. So should be very interesting.

Nice I'd be very interested to see the results, my work bought some 640's for no reason and I'm probably going to steal one for Physx. If its worth it that is... with a GTX560 448.

But Does Cry 3 engine or UE4 engine support phsx ? If not its a pointless thing and that video card is just gonna generate more heat and make your comp more noisy. gl

The OP has said nothing about the games he is playing. I'm going to assume its borderlands 2 and Batman AC since those are the two biggest titles with support currently that people still play.

So where are you getting this Cry 3 or UE4 from???

And while the second card will generate more noise and heat in your example if the games he is playing doesn't support it the card will be idling. And from what i've seen a 650 doesn't pull alot of wattage and has a low fan profile.

Ok finally installed it enabled HybridZ.exe and everything runs like gravy!

One odd plus that I encountered was Lucid Virtu now treats the 640 as an integrated GPU. Very strange! This has improved my score similar to when I had the onboard GPU enabled.

Did a benchie of Batman AC with Physx and it looks good I did have some unexpected dip but I am guessing that it's a demanding game.

My numbers look like this, with everything enabled to max at 1900X1200 and physx set to High

Min: 11
Max: 105
Avg: 60

Only thing I wasn't counting on was that the 640 I got is a two slot design so it blocks my only PCI slot. So currently using onboard sound

 

[tweakboy]

I hope that minimum of 11 doesn't happen throughout the game and is a worst case scenrio. Avg 60fps is what we want.

Ya if he play Borderlands 2 and Batman get the 650 if your gonna stop playing those games anytime soon or dont play those games then no point in a phsyx card. Oh Dirt 3 support phsyx,, hehe gl

 

[tweakboy]

Lets face it phsyx is a bust. First it was a Ageia company then they saw they could get no where so they sold out to nVidia. Now nVidia proudly touts phsyx which doesnt exist in 95 percent of the games lol.

If Cry 3 or IE4 doesnt have phsyx then I say they cancel this stupid phsyx and remove it from the drivers and only install it as a option, not default and what not. gl

DX11 can do everything a phsyx can which is why big companies like EPIC and Crytek don't use it. They apply the same graphics and nature of phsyx thru DX11 programming. gl

 

[sarthakyadav]

i think the gtx650 ti is way too expensive to be a dedicated physx card...man u tell me how many games support physx(although all benefit a lil bit from it)....and u already own an hd 7970,and an i7 2700k...isnt the compute power of the cpu enuf keeping in mind mostly games dont have physx support...n come on u talkin about gettin overwhelmed by eye candy of batman....how much time will u play that game,,or any game in fact...long enuf to buy a 150$ card...i don think so...


well u can always save and u anyways gonna buy gtx7**....wats the point...u already hav a gt650 for dat purpose....when u willl get the gtx7**,u wont need it,nor the gtx650

wow. Thanks for busting the thread up!!

Anyway, since your not following i will give you an update. The OP has already purchased a GPU and is running hybrid PhysX with his 7970. I guess you want to pee on that?

also not sure what you mean by IE4 but the Unreal Engine 4 (UE4) is built with all kinds of goodies. Like real-time Sparse Voxel Octree Global Illumination and....brace yourself......PhysX. UE4 will be the engine powering loads of games for the future. And there goes half your reasoning. Cry3, well i just dont see a lot of developers using that engine but hey, you got one. But what does that prove?? crysis3 dont have physx therefor physX sucks, LOL!!!!! thats so funny.

So to the point:
Perhaps you dont like physx, thats fine. But your opinion is your own. But please dont stomp on others or the threads they create to share their knowledge, love of tech, and experiences.

This particular thread subject may not be of you taste. So you say, " Lets face it phsyx is a bust...... cancel this stupid phsyx....DX11 can do everything a phsyx can" like its a bust yet your energized enough by it to make several post claiming its nothing????huh??? haters gonna hate.

But hey Annisman said it best when he said:

I'm also considering a GTX 650 for dedicated Physc in Bl2, no matter if you hate Nvidia and their Physx tech, it has no doubt got us consumers considering dropping coin on more Nvidia products.

http://forums.anandtech.com/showthread.php?t=2277356

I see more and more people butting in saying, "dont buy physX, it's nothing...." and its funny to me. Obviously, it must be sad for some to see it gain any traction- but if it was nothing at all, no big deal, then why waste your time in a stance against it???

 

[UNhooked]

Thanks for the back up ocre, no worries everyone is entitled to their opinion.

Some think physx is a bust well maybe or maybe not only time will tell. For now I am thoroughly enjoying Borderlands 2. I couldn't care what the rest of the world thinks Once you are used to physx it is very hard to ignore what you are missing.

My interest in Physx peaked while playing Batman AC on a GTX 460 2Win. Then I bought the 7970 and I was like wow what a difference. Obviously the 7970 had better FPS but still knowing what I was missing kept bothering me. So then I began researching how can I have Physx with an ATI card. So figured buy the cheapest capable Nvidia card that can do Physx and that will take minimal amount of power and will run cool

Enter GTX 650 not the GTX 650TI like someone else mentioned. However I was lucky to find a GT 640 w/DDR 5 Ram essentially it's a vanilla GTX 650 without the need for an external power plug.

Also like Dookey mentioned he has 2X 680 SLI and still needed a dedicated physx card. So that should put things in perspective for folks asking me to go solely Nvidia route.

So me very happy atm.

Also like I mentioned Lucid Virtu for some reason treats the GT 640 as an integrated GPU giving me some really cool FPS in benchies. So may it's doing that in games as well.

For e.g I got 218FPS in AVP benchie using default settings.

i think its cool you went hybrid. The 7970 is really amassing and there is no reason to get rid of it for a few physX games. I dont know why people would tell you to go all nvidia if your gonna use physx. There is really no reason to. Hybrid is not hard to implement at all. Did you find it hard?

People who love PC's and hardware usually love to tinker. its a joy just messing with stuff, well for me it is. a dedicated physx card could appeal just for the love of the PC hobby. Well for the old school type, like me. A few years back we used to get all kinds of niche HW that wouldnt have many applications at all. But we did it for the sport, the fun, the love of the hobby. It was all fun back then, back before things got so limited. I loved the hobby bask in the mid 90s to 2007. These days options have become so limited. Its nothing like it used to be. The vast huge options are shrunk to a handful. But.........

Anyway,

i ordered a physX GPU to toy around with too. I have a few things i want to test out. You know just for the sport.....

Not hard at all. Downloaded latest Nvidia drivers and ran Hybridz.exe. Easy as pie. I did have to replace the Physx files for Batman but for Borderlands 2 all I had to do was delete the physxdevice.dll file.

I do agree with the tinkering part. I remember days of the pencil mod for AMD chips, looking for that elusive AIUHB stepping and Twinmos BH5 chips etc. Heck I still have that OCZ VDIMM booster lying somewhere.

But overall like you said I love tinkering with my machine and it's always fun to make something work not in a way it was supposed to be

Found a user who did a Physx shoot out. 650ti was the overall winner but I think if I were to overclock the gtx 650 I should be able to yield similar results. IMHO GTX 650 vanilla version is the best card for Physx based on power consumption, heat, noise and overall gains in Physx. Gtx 650ti is an overkill.

nice find. that guy did a lot of work. I read the thread and this was interesting:

Yes, this one area where the numbers and benchmarks can let you down. You need to decide if the "feel" of the game improves. Sometimes the fps may not go up hugely but it may be more consistent/smooth. My benchmarks are available to download on my site and I did frame by frame recording so a graph could be created to outline that data for smoothness

Yeah I guess it might have helped a lot in avoiding major dips in framerate, which is usually what kills the experience,

I've found that CPU speed will eventually become the bottleneck for PhysX, maybe you could try with a higher clock on your 2600K, or even a lower, to see how that changes things

Also heard that the clock speed of these dedicated physX cards make a big impact. Like a higher clocked 640 is faster than a lower clocked 650 even though the 650 may have more cuda cores. I guess this makes sense in some ways. They will only use so many individual threads as to not hog up so many resources. If the number of physX threads isnt higher than what a 640 can handle at once, then it is all about the clock speed. The faster clocked card will be quicker. But you would also imagine that there will be cases when their are more threads when a lot of stuff is happening at once. Then the higher cuda cores should show superior.


Anyway, i plan on doing a lot of testing myself. Just for the sport of it.

 

[Makaveli]

I'm going to grab this tomorrow it does look like clock speed gives a nice boost.

EVGA GTX 650 Superclocked 1GB GDDR5
- 1202 MHz Core Clock, 5000MHz Memory

 

[Dark Shroud]

EVGA GTX 650 Superclocked 1GB GDDR5
- 1202 MHz Core Clock, 5000MHz Memory

That's the exact card I've been looking at for PhysX for that same reason, that sweet over clock.

I just started looking back into a hybrid setup after watching some of the BL2 videos. I won't be buying either until December as a Christmas gift for myself.

 

[tweakboy]

Oh yeah enjoy Batman and Borderlands 2 . I think a 650 is overkill for phsyx dedicated.

More like a 9800 GT as phsyx or 460 1GB as phsyx.

I hope things pick up for Phsyx I mean I know its nice technology. I just hope more engines buy into it.

I myself am not happy nVidia touts phsyx but it doesn't exist in most games.
As I said if phsyx comes to Crytek 3 or UE4 then ITS WORTH IT!!!

Im just bitter it supports 3 games batman and dirt 3 and borderlands 2

anyhow didn't mean to bust the thread.
