@ObscureNemesis If you have a good performing processor like an Intel i7 you're better off with a software based PhysX that runs through your CPU it would compensate greatly specially on those fast CPUs.
@RenaruX WOW too much but its not possible because MB's that support 4-way sli are designed to support 4 graphics card so if you put 4 580's you wont have space for another one
@aeroaa2 actually its possible if you use 1 slot cards like the hydro copper 2 edition the only problem would be that the last card and the physx card will run at 4x lol
@Xsiter2 Why not try it? This is one of the best reasons of being a PC Gamer, is that we can just try it out and in 10-20 minutes you can find out which is better
I'm using a single slot 9800GT for Physx along with my main GTX480. Mainly because I want to have space for other cards when adding another 480 to run sli
I have an ati 5870 and a gt430 as my dedicated phys card....I was just wondering if I needed a more powerful nvidia card to get better fps while running these cards together
This is very interesting - I was going to use my old 8800GT as a PhysX card alongside my current GTX560, but after this I don't think I will. If the speed of the card is paramount as your evidence suggests, then logically a dedicated PhysX card should be of the same speed (meaning probably the same generation) but with less cores so it's not too overpowered - therefore a GT420 or 520 might be the best bet.
i wonder if connecting the SLi bridge and run them in non SLi configuration and try out physix on one card, there aint any boost, i dont know if these new drivers allow that today, i remember trying it on my 2x 8800gts before, that was along time ago!
If you have 2 GTX 580s just run them in SLI... Are you kidding me..??
Most games don't run PhysX.... But a product that could run PHYSICS, by itself would be neat, "BUT" at that point just upgrade OR overclock your CPU if possible... There is your answer. 2 GTX 580s are enough to tear the keyster out of anything at the moment...
You are completely missing the point... This entire video is demonstrating how much physX saps from a single GPU, and what you can do to offset it for CHEAP. aka non SLI/Xfire.
This is why he is showing a bunch of different results from budget graphics cards.
@fateephat I'm not missing the point, a HIGH end card loses very little running PhysX, it was like .oooo1 or something like that...Watch the Video... Budget Video Cards..??
The 550 Ti is the only budget card in there, and I wouldn't put that in a HIGH end gaming rig. A 560Ti performs the best for the price, and two of those are pretty sick in SLI, I know... Putting in an old crappy card will actually make performance worse, I dare you to try that with a GTS 210... I have seen that as well.
Games are still reliant upon texturing and pixel pushing power. This is mostly due to nVIDIA. Games also push a ton of geometry calculations which are not needed. Why? Because these are the areas where nVIDIA are dominant. Games don't use much compute yet. So a GTX 580 has extra compute resources sitting there idling... enough idling to handle PhysX better than an 8600 GTS.
@RadicalTendencies This is also why nVIDIA is ahead of AMD in several titles. AMD is not sitting there idle anymore though. They appear to be pushing relationships with developpers far more than before. If games leveraged the Compute Power of a 7970, say, you'd have the most surreal experience. nVIDIA is and has been holding gaming back with it's "The way it's meant to be played" developper relationships. A little more competition in this area is welcomed imo.
@loudtrout Get 560 Ti 448 cores. I have one for week now and its running great, games on 1080p easy. And it's like 570 but 'budjet' version. It's more liek 565 ;)
@loudtrout I would definitely recommend it, the price to performance ratio for this card is amazing. Also you get PhysX with it which ATI doesn't have. Going for about 250-300 dollars this card will do most modern games 1080p resolution maxed out with smooth fps.
I have this PC: Processor: AMD Phenom(tm) II X4 960T Processor, 3010 MHz Motherboard: ASUS M5A99X EVO Video Card: MSI N560GTX-Ti Twin Frozr II/OC 1GB GDDR5 Memory: 8GB (2x4GB) DDR3 1600Mhz Patriot Hard Drive: 500GB SATA 3 Western Digital. Fuente: CoolerMaster 600w Extreme Power Plus. And i have a GTS250 1GB from my old PC what you guys think if i use this for PhysX?
@exsnozer the Asus Rampage IV Extreme can handel them i think, it has enough PCI slots, you'll need watercooling though to make them only 1 slot high to maker them fit.
@soapman7x7 i think the ageia cards are not good now as the new cards have the ageia card built onto them, if u have an ageia card hanging around try it, but dont buy 1 as its a waste of cash.pick up a card for physx think your system is good enough anyway the old card probably will slow you down.
I am using 2 gtx570's SLI and have 3 GTS450's SC laying aroung and for giggles added a gts450SC for phys x and only gained 4fps. the gts450 was @ 950mhz oc and the 570's on stock clocks. for me it's not worth the additional heat and clutterd look of a non matching card for 4fps. having a dedicated phys x card would be a bigger improvement when using lower end gpu's like the gts450's and the older gtx 460's. the newer 5xx series cards are pretty much do it all cards and do not need physx help.
ok heres a question what if you have a nVidia card like a 570 or 580 that only supports two monitors and you add something like a gt440 to support a third monitor how would this work out?, also using it to process phsyX
Why can't you see it? The gtx580 rendering power is bottlenecking this test. Do the test with a gtx 590 as main gpu. And then compare gt440..gts450..and gtx 550ti as a dedicated physx card. If you must use gtx580 as main gpu, you should test gt220.. gt440.. and gts450 for the physx job. You use 8600gt then jump to gtx550ti ? lol..
@charlieevoviii You the stupid 1. I was saying about the 57 fps when he use that top 3 dedicated physx card (550ti.. 560ti.. & 580 give the same result). He said he "dont know where the threshold is". If he switch that gtx 580 with gtx 590 then benchmark again with the same 3 physx card/system... that's when he can see the difference between that 3 dedicated physx cards. You are an amateur.. please don't talk too much.
@charlesbego actually i think he means where the threshold for physx cards is. like how far down do you go below a 550ti before you see performance drops. because clearly the 580 560 and 550 ti are all giving the same results.
Just stumbled across this video today and thought I'd rehash some info. A friend of mine that works for nVidia told me that the corporate rule of thumb for PhysX is to use a same generation card (pairing a GTX5xx with another GTX5xx or GT5xx) or a previous generation card at the bare minimum (GTX4xx, GTS450, or GT4xx card) to keep from bottlenecking the PhysX performance.
@goattke I have an easier rule of thumb. Make sure it has at least 96 stream processors. That's really all that matters. There's only a marginal framerate difference from a GT 440 as a dedicated PPU to a GTX 580.
@stalin666666 Say you have 100 CUDA cores. Physx only using 40 at full speed rendering. Say your card has 120, but the 8600 gt only has 32. Dedicate the card to physx and you will have a slow down. Physx requires 32 minimum as a "it should run the littlest of demos at no problem", this does not include full scale games developed now. In games like gta 4, you can have a Geforce onboard integrated gpu run the graphics. As long as you have a quad core cpu to make up for the Physics Processing.
Would be more interesting with a not so overpowered main Graphics-Card. Like a GTX 550 as a main graphics card. Your Test is like checking if a Ferrari is fast enough for city-traffic at noon, which is not leading to an interesting result.
2 Reasons:
1) Its not reasonable to spend >400$ for a piece of hardware which is worthless in 2-3 years, no matter how good it is today.
2) Most people would have a spare 8x00 from before the last upgrade, which could prove useful to a 550.
@underwatercookie Disable it from a game? Rewrite the game with a different physics engine.. wouldnt help anyway as you would get the same, if not, worse results.
Its a nice set up i use to have 2 480s one burnt out i was gonna replace it then i realized it wasnt such a huge deal. After all the human eye can only see around 30 FPS i figured it wasnt worth dropping a couple hundred bucks to replace it
xcuse me, witch motherboard are u using? and another thing, what do you think about doing something like this with 2 GTX460 in SLI and an additional GT240 for the Pyshx? thanks for reading!
@blackelfwolf it's close to impossible actually because the drivers for NVIDIA and AMD conflict with each other and thus, they don't allow you to run a dedicated PhysX card with a main AMD gfx card.
it was possible at one time by using hacked/modded drivers (back when the GTX 400s were just being released i think) but i'm not too sure how it is these days...
@sexking83 Physx is a gaming enhancing feature developed by Ageia, later bought by Nvidia. Few games use it though, but if you happen to play many of those games, it is a nice feature to use.
@exoticg9 the thought behind it is to divide the processing of the PhysX and the graphical processing to 2 graphical cards , boosting the overall FPS rate
please guys i need help regarding the bottlenecking issue.......does insalling more gpu's slows the graphic performance.......and can please someone tell me meaning of bottlenecking....i have read on an article that the game which uses the physx....will stuck or lag...while this dedicated physx setup os installed.........please..@linus help........and those who know the answer to my question please help me ...ok
i wanna use my gtx 285 as a ded-physx when i overhaul my pc q1 or q2 of next year. anyone think its gonna bottleneck my gpu (which is going to be a kepler)?
@MontyTFox I can use it in metro 2033 and it's clearly running. I haven't tried it on other games though. They give you the option to run it off a Nvidia card or off the cpu, but it only uses 1 core on the cpu so you need a powerful processor or the frames will be terrible which is why you're supposed to use a Nvidia card.
so, i got 2x gtx 460 1gb's in SLI for rendering, and left the settings to automatically select cpu or gpu to do physx, but i am thinking about putting a dedicated physx card in, but like with your results, im affraid of bottlenecking the main cards. what would you think about a heavily oc's / bios flashed 9800gx2 for dedicated physx? would that be ok? thanks for your help
I'm running two GTX470s in SLI with CPU as Physx. I've been researching if I should/could put my 9800GT as Physx, but after seeing this GREAT video, I will not do it. Additionally, I don't think my 800W PSU could/would handle that.
Hey guys im doing a new build in the coming year. on a G1 assassin it says it can have 3way nvidia sli so that confused me a bit can i have 2 590s because its 2 cards. yet 4 gpus so its in a way 4 way sli so i think id be able to run 2 590s on it with it being such high end. also with the 590s i was thinking of getting a 460 for dedicated physx but then again that would mean 5 gpus is it possible to do that im not sure because of the nature of the cards and what there being used for
Hey Linus!. In my computer I can only find 1 PCI-E cable to my Graphic card. So if I buy a graphic card fx one of the new graphic cards and it requires 2 PCI-E cables. What shall I do?. My system. Radeon HD 5770, 8 Gigs of ram and 6x3,20 GHz processor. If I play World of Warcraft at full graphics I lagg a bit. If I want to improve my FPS what new upgrades for my pc would be could. Please thumps up so people can see :) and wich new things to replace them with :D ?
I think these results simply mean that GTX 470/480 and of course 580 do have a way better physx engine because they have more cuda cores,faster memory and shaders.I do dedicated physx by combining one or two HD 6970s with one low profile GDDR5 GT440.I can't use my previous GTX 470 with it because it is dual slot but i'm pretty sure that a GTX 470 would be a way better to deal with physx in my case.But well it was the only available fermi low profile GDDR5 card that i could find.
What about the old agea physix dedicated cards? Are those any good or are they gona be a bottleneck?

michaelkitselaar 3 months ago
Why can't you see it? The gtx580 rendering power is bottlenecking this test. Do the test with a gtx 590 as main gpu. And then compare gt440..gts450..and gtx 550ti as a dedicated physx card. If you must use gtx580 as main gpu, you should test gt220.. gt440.. and gts450 for the physx job. You use 8600gt then jump to gtx550ti ? lol..

@charlieevoviii You the stupid 1. I was saying about the 57 fps when he use that top 3 dedicated physx card (550ti.. 560ti.. & 580 give the same result). He said he "dont know where the threshold is". If he switch that gtx 580 with gtx 590 then benchmark again with the same 3 physx card/system... that's when he can see the difference between that 3 dedicated physx cards. You are an amateur.. please don't talk too much.
charlesbego 2 months ago
@charlesbego actually i think he means where the threshold for physx cards is. like how far down do you go below a 550ti before you see performance drops. because clearly the 580 560 and 550 ti are all giving the same results.

@umeshtheman I mean that if you got 2 580's i don't think that you will run 1 as physx and 1 as a normal graphics card but both of them in SLI.

@ItalyNerf ....usually but...considering that this is a case where u jus wanna test how well a 500 dollar card does physx.....then its different!!!!
umeshtheman 2 months ago
@ItalyNerf He wasn't using a GTX 580 as a suggestion, it was a test to see the best results possible as a comparison to the lowest (ex. the 8600).

Just stumbled across this video today and thought I'd rehash some info. A friend of mine that works for nVidia told me that the corporate rule of thumb for PhysX is to use a same generation card (pairing a GTX5xx with another GTX5xx or GT5xx) or a previous generation card at the bare minimum (GTX4xx, GTS450, or GT4xx card) to keep from bottlenecking the PhysX performance.
goattke 3 months ago 44
@goattke I have an easier rule of thumb. Make sure it has at least 96 stream processors. That's really all that matters. There's only a marginal framerate difference from a GT 440 as a dedicated PPU to a GTX 580.

stalin666666 4 months ago
@stalin666666 Say you have 100 CUDA cores. Physx only using 40 at full speed rendering. Say your card has 120, but the 8600 gt only has 32. Dedicate the card to physx and you will have a slow down. Physx requires 32 minimum as a "it should run the littlest of demos at no problem", this does not include full scale games developed now. In games like gta 4, you can have a Geforce onboard integrated gpu run the graphics. As long as you have a quad core cpu to make up for the Physics Processing.

Would be more interesting with a not so overpowered main Graphics-Card. Like a GTX 550 as a main graphics card. Your Test is like checking if a Ferrari is fast enough for city-traffic at noon, which is not leading to an interesting result.
2 Reasons:
1) Its not reasonable to spend >400$ for a piece of hardware which is worthless in 2-3 years, no matter how good it is today.
2) Most people would have a spare 8x00 from before the last upgrade, which could prove useful to a 550.

wouldn't a dedicated PhysX card only be good if you had an AMD card as your main graphics card? Because AMD doesn't support physx?
blackelfwolf 5 months ago
@blackelfwolf it's close to impossible actually because the drivers for NVIDIA and AMD conflict with each other and thus, they don't allow you to run a dedicated PhysX card with a main AMD gfx card.
it was possible at one time by using hacked/modded drivers (back when the GTX 400s were just being released i think) but i'm not too sure how it is these days...

@sexking83 Physx is a gaming enhancing feature developed by Ageia, later bought by Nvidia. Few games use it though, but if you happen to play many of those games, it is a nice feature to use.

MontyTFox 5 months ago
@MontyTFox I can use it in metro 2033 and it's clearly running. I haven't tried it on other games though. They give you the option to run it off a Nvidia card or off the cpu, but it only uses 1 core on the cpu so you need a powerful processor or the frames will be terrible which is why you're supposed to use a Nvidia card.
lemonsyay1 5 months ago
so, i got 2x gtx 460 1gb's in SLI for rendering, and left the settings to automatically select cpu or gpu to do physx, but i am thinking about putting a dedicated physx card in, but like with your results, im affraid of bottlenecking the main cards. what would you think about a heavily oc's / bios flashed 9800gx2 for dedicated physx? would that be ok? thanks for your help
ThePCgamer1989 5 months ago
I'm running two GTX470s in SLI with CPU as Physx. I've been researching if I should/could put my 9800GT as Physx, but after seeing this GREAT video, I will not do it. Additionally, I don't think my 800W PSU could/would handle that.
Great video. Thumb up.

Hey guys im doing a new build in the coming year. on a G1 assassin it says it can have 3way nvidia sli so that confused me a bit can i have 2 590s because its 2 cards. yet 4 gpus so its in a way 4 way sli so i think id be able to run 2 590s on it with it being such high end. also with the 590s i was thinking of getting a 460 for dedicated physx but then again that would mean 5 gpus is it possible to do that im not sure because of the nature of the cards and what there being used for
onimushaninjavideos 5 months ago
@onimushaninjavideos At first you should be clear that 1 590 is OVERKILL. 2 of them are even more overkill!
Second: Multi-GPU= Micro Stutter! More GPUs, worse stutter!
A dedicated PhysX Card wouldn´t run in SLI with the other two, so it would be like a normal card which wouldn´t be used beside PhysX!
YOu don´t need more SLI. Only stick the 590s together and let the 460 alone in its slot

Hey Linus!. In my computer I can only find 1 PCI-E cable to my Graphic card. So if I buy a graphic card fx one of the new graphic cards and it requires 2 PCI-E cables. What shall I do?. My system. Radeon HD 5770, 8 Gigs of ram and 6x3,20 GHz processor. If I play World of Warcraft at full graphics I lagg a bit. If I want to improve my FPS what new upgrades for my pc would be could.

Amuffin456 5 months ago
@LinusTechTips
I think these results simply mean that GTX 470/480 and of course 580 do have a way better physx engine because they have more cuda cores,faster memory and shaders.I do dedicated physx by combining one or two HD 6970s with one low profile GDDR5 GT440.I can't use my previous GTX 470 with it because it is dual slot but i'm pretty sure that a GTX 470 would be a way better to deal with physx in my case.But well it was the only available fermi low profile GDDR5 card that i could find.
