If you were to compare the PS3 video card with a pc video card......WHAT WOULD IT BE?

For example a 4850 or 9800gt?

Or compare the x360

If I remember correctly, it's comparable to the 7800GT.

The 7900GT, X1950 and the HD 4650

The xbox 360 is even worse

Are you sure? The PS3 video card i think is better than the 7900GT, X1950 HD 4650. After all, it doesnt lag ever in MW2 or COD4.

PS3 and XBOX360 are 4 or 4 generations behind the current PC High End card. Take note that PC video card updates at least 2x a year.

PS33 games are set at 720P(not 1080P) which is way low compare to the current games in PC.

Basically a 7900GT with half the memory bandwidth.

That's because it is running at 1280x720.

actually it runs at 600p

It has much better drivers, making it much more efficient with its power. The PS3 gpu has 1.8 TeraFLOPS of processing power btw, which is 50% more than an HD 4870.

Like has been previously said, the PS3 has about a 7900GT and the Xbox 360 uses an R600 variant probably around an HD 3600 or HD 2900 XT; both DirectX 9. The difference is it has some processor cores that can also be used for graphics processing and it only runs in 720p or sometimes lower which is at best 1280x720. You can run at that resolution with, well, a 7900GT. The consoles upscale the image to 1080p, but there's a very large difference processing graphics at 1280x720 and 1920x1080 (which you can actually demonstrate using ARMA II on the PC -- graphics settings allow the resolution to be in 1080p but it can render everything in a lower resolution, case in point); need I count how many pixels different that is.

Now of course the consoles don't look terrible and are definitely comparable, but you also have to keep in mind these things are designed from the ground up to work with the development platform people make the games on. That means no driver issues/optimizations, no worrying about different display settings, no worrying about memory or processor speeds. If AMD or NVidia took the time to optimize each of their GPUs they sell you for your exact hardware and that exact GPU with that exact game the PC would probably beat out console performance by multiples of ten, as it should. Also, if you were able to strip the operating system and just run bare games off of, well, something, that would help.

As we move into DirectX 11 and adopt ATi's HD 5 series and (hopefully) NVidia's new cards I think you'll start to see a disparity in console graphics until it's time for their new revisions/replacements.

the reason why xbox360 and ps3 run games at 720p so well is because they are designed to video games and utilizing 100% of the power, while a computer is designed to do much more.

For example the ps3 cell cpu runs pararrell with the 7800gt making the system very powerful. the cell cpu is more powerful than any gaming cpu on market while the GPu is rubbish. cell is 7 cores.

Unlike PC, PS3 doesn't have a Heavy Operating system running behind.
(That's what I read in a comment on a similar question )

Yeah keep dreaming.

The cell consists of 1 PowerPC core and 8 SPEs (one of which is disabled to help yields and one of which is dedicated to running the OS). SPEs are very simplistic and are in no way comparable to any current CPU core from AMD or Intel.

It's more of a R500 / R600 hybrid. If anything it leans more towards a X1900XT in design.

HD 4870 has 1.2 teraflops computational power as seen here on amd's website.

The PS3's gpu has 1.8 teraflops computational power (I never said it was all used effectively) as seen here along with many other sites that did reviews on the PS3 when it came out.

Finally, the PS3 has 50% more processing power than an HD 4870; this is just simple math (1.8/1.2 = 1.5 = 150%, meaning a 50% increase).

Thats because its running at a lower resolution, and the games are specifically designed for exactly one variant of hardware. Console hardware is actually pretty whimpy compared to a gaming PC. Games such as Dragon Age make this point for me. The console versions are stripped down quite a bit to run well there, and MW2 looks much better running in Eyefinity at multiples of the resolution a console could muster. We can max out graphics settings that aren't even available on the console version.

Not that I'll give Infinity Ward a dime until they inluded independent servers. Bastards.

Arbitrary claims of computational power that are stated only by the companies themselves are completely meaningless. They could say it had 5 teraflops of power, there's no way to check this since they didn't give out the specifics of how they determined the number.

A 7900GT with half the memory bandwidth and half the ROPS is not 50% faster than a HD4870. Check any benchmark even comparing a full 7900GT with a HD4870.

Memory bandwidth has nothing to do with computational power, which is probably one reason the PS3 doesn't have the performance of the HD 4870.

Ok, so now we can't trust any manufacturer's specifications. How do we know the HD 4870 even has 1.2 TeraFLOPS computational power? Did you disassemble one and reverse engineer it to count the rops, shader processors, etc.? Just because we are told it has 800 Shader processors and 16 ROPs, what if AMD is lying?

put in a 4670 on top of an athlon2 x4 620 and run mw2 @ 720p. i'll cut my dick off if it hints a tiny bit of LAG. and yeah turn vsync-on as well (sync every frame) to match that frame-capped visuals of a console.

Where is TGGA when you need him...

I mean, seriously, Nvidia wouldn't have bothered with producing any new cards at all if all they needed to do was make a 7900GT with a 512bit bus to stay on top.

And yes, you can look at a piece of silicon with a microscope and actually count the stream processors, etc. AMD's claim of 1.2 teraflops is at least plausible. A G70, with no known changes other than a reduction in memory controllers and ROPs, does not suddenly gain 400% of its performance once it's put in a PS3.

The Sony claim of 1.8 TFLOPS is simply obviously false. It makes no sense whatsoever in context of the history of gpu technology. Period.

I asked if you yourself have, since we can't trust manufacturers claims as you said. Also, FLOPS are a measure of theoretical processing power, and it certainly doesn't always equate to real world processing power (as we see with the NVidia RSX and even with the ATI Xenos). Also, processing power of the GPU doesn't necessarily equate to graphical performance either.

Im shutting this down. If you really want to know about consoles vs PCs, either look up old threads, which contain the info, or google is your friend
