GTX 460 192 bit?

[spaceman1701]

Hi,

I was looking at inexpensive/mid-range graphics cards for a build I am going to be starting soon. At first I was looking at the Radeon 6870 but it is a little bit more than I want to pay. I then found the GTX 460 Super Clocked for EVGA. I did some looking and found that it was about as powerful as the Radeon 6870. I found it wired though that a GTX 460 only has 192 bit memory bus width, I though all of the 1Gb cards had a 256 bit bus width. Will this noticeably affect performance and does the SuperClocked 460 really perform similarly to the Radeon 6850/6870/GTX 560 (non Ti)?

Get the 256 bit. $5 more after rebate. It will make a difference at higher resolutions.

AlsoGTX 460's overclock well. I have GTX 460's stock at 733MHz core clocked to 840MHz. The card I showed you clocks stock @ 833 so maybe it will o/c even higher. Makes about a 12-15% difference in frame rates.

A 6870 is reputed to be a faster card.

Uhhh. You linked the GPU. I do not plan to ever OC my GPU so that's really not an option. Is it the bus width that makes the 12-15% FPS difference?

 

[DelroyMonjo]

Bus width will make a difference depending on monitor resolution and graphics settings in the games being played. If you have a monitor with 1600X900 resolution or lower compared to 1920X1080 or more, bus width will be less important. Bus width also affects graphics settings like anisotropic filtering, high shadow-low shadows, water effects and so on. "Eye Candy".
Overclocking increases the FPS at whatever those above settings are.

 

[spaceman1701]

OK. I currently have a 1600x900 monitor but I am planning on upgrading to 1080p in the next year or so. What is the GPU you suggest? And will these factory OCed 460 perform as well as a Radeon 6870? Also, the link you posted is the same one I posted...

 

[spaceman1701]

avoid the GTX 460 192-bit like it was the plague..
256-bit or better in gaming cards nowadays.

Are they really that bad?

My bad, you are correct! Should have been : http://www.newegg.com/Product/Product.aspx?Item=N82E16814130752
That's the 256 bit model.
A 6870 is reputed to be faster than a 460 256bus. Just wait for the AMD fanboys to tell you that or go read some video card reviews.

Also as for the 192 bit bus I thought I had explained the difference between 192 and 256 bit in my previous post. If you are getting an HD monitor DON'T get a card with a smaller bus if a higher bandwidth is possible within your price range.

the 192 bit performs in the same category as the 6790, it takes the full 256 bit to compete even with the 6850. They are NOT in the same league as the 6870 or 560
With the 7770 just launched, i'd keep my eye out on a 6850 deal. This looks to be the best deal now, might even go down in the next couple weeks

I might be wrong, but i think the 460 SE is what they are referring to as the 192 bit. Same performance class either way.

A little history about the 192 bit 1GB GTX 460. Its actually based on the GF114 chip, just like the GTX 560 and GTX 560 Ti. That's what allows for the much higher clocks than the original GTX 460 (which is a GF104 chip). If you do not plan on overclocking your card the GTX 460 1GB (192 bit) will probably be as fast or faster at its factory 867 Mhz than the GTX 460 256 bit at its factory 720 Mhz. Yes, the original GTX 460 has a greater bus width, but that extra 147 Mhz on the version 2 card will make up for that and more.

A stock HD 6870 will be faster than both, but there won't be much difference until you hit 1920x1200 with AA applied.

Here's a review of the HD 6870 and HD 6850 when they first came out. They included an eVGA GTX 460 FTW (256 bit) that is factory overclocked at 850 Mhz. It handily beats them both in almost every bench.

Here's a review of the EVGA GTX 460 768MB Superclocked. Its also a 192 bit card, but with only 768MB of VRAM. Its also only clocked at 763 Mhz at it still matches the GTX 460 1GB (stock 675 Mhz) except at higher resolutions. That's why I'm pretty sure the version 2 clocked at 867 Mhz with a full 1GB of VRAM would beat the 256 bit version clocked at 720 Mhz.

If you're not going to overclock the card yourself and your budget is tight I'd get the GTX 460 1GB 192 bit Superclock.

if you can get a 6850 in the same price range I would get that. It's a little faster in most games but the biggest thing would be physx. As soon as it's enabled the performance will drop. If you look at the reviews closely, the games that use it won't be benched with it enabled. Some sites will explain this up front.

A stock HD 6850 will not be faster than either a GTX 460 256 bit @ 720 Mhz or a 192 bit @ 867 Mhz. In fact it will be slower. Again, the O.P. will not overclock his card.

 

[Boopoo]

performance wise, a big let down.
even the HD 7770 can match the 192-bit versions of the GTX 460..
give me a HD 6870 if you can wait and save then GTX 560 at least, I'm a nVidia guy..

Actually the 7770 is matching and or trading blows with the GTX 460 1gb not the 768mb version.

6850 is about the same performance as GTX 4601gb and really it is a bit faster over all but whom is spliting hairs really.

 

[Boopoo]

not talking about the 768MB version.
there are 1GB 192-bit versions.

and to be honest, for a couple of dollars more you can get the HD 6870 on sale..

I like the 6850 cause I can run two off a PSU that is only meant for one card.

 

[spaceman1701]

Wow! Thanks for all the replies! The Radeon 6850 seems on par with the stock (675mhz) GTX 460. From what I see on Andantech bench, neither clearly is more powerful than the other. http://www.anandtech.com/bench/Product/539?vs=542

So if I take into consideration the 50mhz factory OC on this GTX 460, than would it not out-perform a stock 6850 (which is the same price)? http://www.newegg.com/Product/Product.aspx?Item=N82E16814130752

Also, how easy is it to Overclock a GPU? I have never heard much about how to do it, besides seeing a short video on MSI Afterburner.

 

[Boopoo]

might also mean it's a good PSU..

I was more in referent towards the low Max TDP of 125Watts the 6850 has and that it only takes one 6 pin. My old GTX 275 that the 6850 CF replaced took 220Watts Max TDP and had half the power of the CF 6850. Any PSU with 2 6pin PCI-E power dongles will power up a 6850 CF rig no problem thats the magic and value of these wonderful cards.

OCed 6850 can best the GTX 570 in some titles.

 

[spaceman1701]

Ok, so then I guess the question is which card is easier and better to overclock. I have no idea how to change coolers on the cards so I guess which ever one can handle the best OC. Which one do you all think it is? I don't want to change voltages.

 

[Boopoo]

never the level a GTX 570....
GTX 560 Ti if your lucky.

OK I send you some links that says in some games an OCed Cherry Picked cream of the crop Msi Cyclone 6850 does beat on a GTX 570. I know it's just in a few games but for a pure mid range card to beat a high end card that cost well over $100 more is nothing short of remarkable. http://www.overclockersclub.com/reviews/msi_r6850_cyclone/7.htm

 

[spaceman1701]

If I could OC either of these cards to the speed of a 6870, that would be great. Is the cooler on this card better than on the Sapphire? http://www.newegg.com/Product/Product.aspx?Item=N82E16814150515

Afterburner is very easy to use once you've done it. To change clock speeds you have to move the slider with your mouse first, then to get the exact number you want use the left or right arrow key. Next slider. When done with the settings click on apply and then profile, pick a number, use 2 and keep 1 for the original settings. Leave the fan on auto for now and and you can ,ook into that later. Clock up in small steps, about 10-20% of original speeds. Then benchmark it using 3DMark or Unigine Heaven 2,5 and save the results. Keep clocking until you see a noticeable improvement in frame rates or until the program refuses to run or shows artifacts or tearing on the screen. You may have to play a game to see artifacts since the won't necessarily show up in benchmarks. I got a 12% FPs increase for a 10% overclock. Your mileage may vary.
That's how I do it on Nvidia cards. AMD cards might have a slightly different scheme.

 

[Boopoo]

not important, it's not like he's getting a GTX 570.

Well that is just highly subjective a 6850 beating a GTX 570 and then you say it does not matter cause he is not getting a GTX 570 you are right he is looking at a 6850 that costs over a $100 less than a GTX 570 and beast it in some games and that is extremely important and relevant to the cause.

 

[spaceman1701]

Ok, thanks. So is there any facts that show what GPU is better for overclocking? All of these GPUs are the same price and preform almost the same, so does it matter which one I get?

 

[spaceman1701]

OK whatever, moving on....
nothing has changed, a few dollars more and get the HD 6870...

I am on a very tight budget and I really rather not spend 30 more dollars. I have to draw a line for the price somewhere, and right now it is at $700 (Without Windows).
