Lower res v Higher res OC'd GPU'?

Hey all, here is a question on my mind.

What should theoretically perform better.

A lower res card at 1440x900 or a higher res and overclocked card at 1650x1080?

Its bugging me.
So i decided a good discussion was in order.

Thanks

It depends on a lot of factors: card's clocks, memory size and type, bus width, amount of overclock, etc. They could theoretically output the same FPS and they could theoretically outperform the other.

 

Yeah. It's way too vauge a question to have a meaningful answer to.

 

your looking at about 36% more pixels to render, i know performance does not scale linearly with pixel count but it should tell you that ocing will not get you up to the same performance level going from wxga+ to wsxga+.

 

Your right, this was quite pointless without details, so here goes

ATI HD 4850 Mobility - DDR3 Ram - 512mb @ 1440x900
500 Core Clock
500 Shader Clock
850 Memory Clock
256 Bit interface
1440x900

v

Overclocked GTX 280m @1650x1080
Core Clock 625
Shader 1625
Memory Clock 1000
256bit interface
1gb Gddr3

This seems to be biting me at the moment, from what i've seen i'd expect the gtx 280 to have much more bite but am unsure. After all it has so many more pixels to render.

Cheers

Dude, if you wanted me to run at 1440 x 900 all you had to do was ask

 

They need to be on native, since downscaling can cause some loss of quality.

I only used you as you had reference to GTX 280m Overclocking (Do i sound evil?)
And i know the Desktop GTX series are deadly, im just wondering about the notebook ones.

 

they are completely different unfortunately.
the 280m is about the same as the 8800gts 512.

 

Hmm, somehow i dont believe that is accurate.

The 280m GTX should perform within the region close to the Desktop 9800m GTX, at the very least 98 series.

 

Benchmark wise 280m GTX performs the same as an 8800GTX (desktop). If im not mistaken the difference between 8800gtx and 9800gtx is not that big so i guess you could say that.

 

Its also a farely new release so i recon it will really shine in a month or so, atleast i hope so.

So is it safe to assume that performance levels vary hugely depending on the amount of pixels that a GPU will need to render?

 

8800gts and 9800gtx are basicly the same.

 

Relatively close but not as much as 8800gtx is to 9800 gtx.

 

Umm, my clocks are basically the exact same as a G92 8800 GTS. I do have double the memory though, which can help. They're the same core, just the 280M is die shrunked. The 9800 GTX, 9800 GTX+, GTS 250 are also very similar, but I can't reach those clocks.

I don't know why you're comparing 2 similar tiered GPUs at different res, but whatever.

 

Well the GTX280m certainly seems it could out rank the 4850, and i want to know if this is true or not as the GTX 280m could be concidered a future upgrade
