*GTX 260/280 Unofficial TPU! Thread*

[mudkip]

I had read that 55nm GTX260 using the on-the-fly voltage change on evga's voltage tuner wont work it's because they had change the voltage regulator to cheaper ones and I doubt changing the bios voltage will work.



so I'm stuck at 1.12v

If I were you I'd just try it, you can always flash your original bios back.
It's only seconds of work.

while gaming my card hits 80c thats with the OC applied. I'm thinking I can't go any higher because of my temps

 

[mudkip]

from 0.825v to 0.775v

ey o tatty or anybody.. could you post a screenshot of your max overclocked 275... gpu-z.. just to compare to the max oc 280.. and maybe give an opinion on whos fastest.. i meen maby drivers is more tweaked in favor to the 275 to day to make it shine and be noticed.. i meen look at those fillrates rendering speeds and that 161.3gb pr second bandwidth loop for the 280..


anyone??

 

[Kursah]

Why are you using such an old driver stinzza? One of my favored drivers has been the 182.48 (iirc)...I'm on the newest driver now, that also might be a factor as I doubt there's even support for the 275 with that older driver and with it missing optimizations for the GTX series you're also missing out on performance, in some areas it might be minor, in some areas it might be a very nice improvement.

Nice results and a decent oc man! I'm quite content with my OC'd 260-216 and 1080p, game on!

 

[stinzza]

just wondering if the 275 IS better then the 280.. i got my doubts i must say...

 

[Kursah]

Well fwir the 275 can oc a tad further, if you look at some of W1z's video card reviews the 275/280/285 can come really close in performance. If I had to choose a card now it'd be the 275 tbh. I wouldn't say it's clean cut better tbh, if anything I'd call it more of a tie. They have the same amount of shaders but the 275's shaders are faster, going from stock vs stock, it seems the 275 is a little faster out of the chute. Sure the 280 has a tad more raw power and bandwidth, but shader power is about the same and that's where big differences can be made.

I'd say check out the TPU GFX card reviews and check out W1z's top notch graphs, the guy works really hard to keep them consistent and accurate so they're definately worth a look (just find the most recent vid card review(s)).

Sorry I couldn't be more help, but like I said from what I've read here and elsewhere the 275 is generally a tie, sometimes edging out a 280, never by much though.

 

[stinzza]

hehe.. well i agree in a degree.. raw power is as it is.. but allsow is new tech ey..

 

[mudkip]

GTX275/280/285 are almost performing identical never much more than 1-3 fps at the same clockspeeds.

I love how nvidia rebrands their chips lol.

Can't wait for the GT300

 

[stinzza]

but the 4 extra rop`s on the 280 over the 275 must do have a say.. whether the 275 got a "bit" faster shaders..

Yes, yes it is. 275 is a 55nm chip that handles heat and power better than the 280. It clocks much better at the same heat output as the 280.

Since they are both the same price I would go 275 all day.

yes i know about the heat.. but can it justify the extra 4 rop`s

 

[Kursah]

It can, check out W1z's review graphs as I suggested before...think of it like the 9600gt vs 8800gt. The 9600 had much less power but could have much more raw speed, where-as the 8800gt had more raw power but not as much raw speed, so granted those two weren't as close, many saved a ton of money going 9600GT and oc-ing the snot out of it to attain the next level of power. The 275 has most of the 280's power and more speed, so in the end in a highest OC vs highest OC comparison I believe the 275 would win, but again like I said before not by much.



Here's a link to the beginning of the gaming performance graph section, take a look thru it. I trust W1z and his graphs without a doubt consistent and accurate.

well is it possible that drivers are more optimiced for the 275 bechause the 280 is not at this time being produced.. that in time things will show.. bechause the 280 got a lot of texture speed and bandwith..

 

[Kursah]

Sure it's possible, but again I don't think you'll see the 280 or 275 ever pull clearly ahead, though you still may wanna consider updating your drivers man...there's been a lot of good added in the 18x and now 19x series of drivers.

TBH it's not suprising at all that a newer, slightly lower-end card is just as fast as the older, higher end card...that's the trend technology goes man, especially in the GPU arena. The specs don't always mean everything, especially since many forget that there are some aspects of the original GTX2xx gpu's that aren't used or included anymore on newer GTX gpu's, that helped with higher clockspeeds, lower fabs (55nm), lower costs, etc. See the OP for more info from the GTX's initial release and release reviews.

 

[stinzza]

but the 275 is not routed diffrentlig in the gpu or on the pcb..i may be wrong there.. but the extra 4 rop`s.. what about them..

 

[Kursah]

"not routed differentling in the gpu or the pcb"....?
The 275, 260 55nm, 285 use different pcb and power designs than the first models, along with the gpu's also being different as I stated above, more for the better though.

On the ROP's, who really cares if the performance is still good or even improved because if removing a few things helps with a smaller package that has higher clock speeds and ends up being even or faster than an older higher-end product...does it really matter? Who knows man, we didn't design it, and really focusing on something like that when real-world gaming performance or even benching performance is what really matters. If the 275's clock to make up for the difference in what it's missing in comparison to the 280, and runs cooler to boot, and costs less, there's no point in worrying about it. I'd say start googling because I don't think you'll find that answer out here to an explanation you'll accept or that is a true answer that really only NV or GT200b engineers might be able to truly answer.

They are all same cards, you can't do different drivers for them. Only one that differs is GTX 295 as it depends on SLI performance. I still didn't get your point from all those posts. Do you own a GTX 280 or plan to get a GTX 275/280?

Reason GTX 275 does so well is because it's clocked higher stock. Nothing to do with being newer or 55nm. Reason why it's clocked so high, is because ATI released 4890.

More ROP & memory doesn't hurt, but it'll come down to what shader level the card can do. There GTX 275 will most likely clock higher.

I like my GTX 280, but I wouldn't cry if I had to use GTX 275 in stead. Even though it never was a high end card and is way cheaper to make it has it's positives, like VRMs you can actually cool

IMO NVIDIA killed two of their cards with one new, GTX 260 & 285 had a perfect spacing. Now with GTX 275 you get the cheap price of GTX 260 and the performance of the GTX 285, there is no reason to buy the other cards. Of course you also can't go wrong with any of the series, so in the end it doesn't matter

Had an occasional strange glitch where it didn't seem to go back to 3d clocks under 1.09, so am using 1.10v for now, no more problems. It may have to do with the "adaptive" mode for power management in the new drivers, I'll have to test more. Every game I throw at it under full oc runs perfect with 1.10v. Interesting!

 

[OnBoard]

It may have to do with the "adaptive" mode for power management in the new drivers

That power management is nothing more than forcing GT200 cards to 3D clocks all the time or the other setting like it has always been. NVIDIA's claim that it would be for all 9 series and up is wrong, neither 9x00GT or 9800GTX(+) has 2D clocks.

 

[rizla1]

just looked at my load temps after playing grid 50c . and the 9.4 amps 112 watts

 

[mudkip]

That power management is nothing more than forcing GT200 cards to 3D clocks all the time or the other setting like it has always been. NVIDIA's claim that it would be for all 9 series and up is wrong, neither 9x00GT or 9800GTX(+) has 2D clocks.

Why would they always force to 3D? Or what is adaptive power mode exactly?

Meh...that kinda stuff, who cares, if your chosen product/brand runs the games good, then it's not that big of deal either way imo. Choosing a GTX260 over an HD4870 over a year ago was much more than performance comparison as both of them were very close with the 4870 being a little cheaper at the time. But none-the-less, this thread is about supporting the GTX series of cards, not dogging the other guys' stuff tbh. I'll support what I have at the time and I'm glad this thread has grown so well, and I'm hoping to keep it from fanboy-ism stuff at this point.

That article has some ok points in it, but I'm more of an enjoy it kind of person than benchmark and hard-core compare anymore...if an HD beats my rig in a game...oh well...mine still runs smooth and that's all that really matters to me.

Are you planning on getting a GTX series or do you have one that's not listed in your sys specs? The GTX280 is a beast of a card, but I'd still rather get the newer 275 still...and I prefer w1z's comparisons in his reviews, the man worked many hours to be consistent and has for yeras, I respect that and know that...where-as other sites I'm just taking their word for it...not saying they aren't, but not saying they are either.
