XBOX GFX benchmarks

[MadEye2]

a friend of mine has an XBOX and I was quite impressed with the quality of the graphics on it. I read up on the specs for the machine but I can't find any specs that I can compare with PC benchmarks. It's probably been asked before but does anyone know where I can get the benchmarks for the console from? Is it possible to run benchmarking software on XBOX linux/windows projects or are there no drivers available just yet that support it's GFX chip fully under an OS?

It's a P3 ~700MHz with a ~GeForce3... it blows, but it blows away PS2 or GC!

I guess if you have a modded Xbox, you could install GentooX, use WINE, and watch any of the 3DMarks crash and burn...

 

[MadEye2]

Nope, I have a GameCube and I'm quite happy with it thank you very much yes yes. What cards do the GeForce XBOX chip/card compare with in terms of raw power and how do they compare with the code optimisations? You know, in an estimated guess.

I'm interested in buying one actually, when this windows project has developed further I'd like to use the xbox as a mdeia player and net browser, just so I can save on the electricity bills and not impair my hearing. I might try Linux, but I'm scared of the idea, even though I've used AmigaOS for years.

It's the same cards you get in your computer. The xbox is a computer with a modded windows 2k to play xbox games. If you want benchmarks, just look at the benchmarks of a p3 with a geforce 3. Sure the xbox has less overhead, but what does that matter? It's still old hardware compared to what most computers run today.

I heard that the Xbox has a custom made video card by nVidia. Plus, how can a GF3 run games that some GF6's can't run today?

 

[LTC8K6]

Not to mention the resolution.......

 

[Todd33]

It's a special GF3 with some GF4 features. It can run games because it has high bendwidth to the CPU via shared memory. Remember most games are rendered at 640x480 to produce 480p.

What are you talking about? PC games have to be nerfed before put onto any of the consoles because they are all weak compared to PC's. A game on the xbox that a PC can't handle? LUDICROUS!

 

[Mrvile]

lol no need to get violent.

Anyway I don't know much about consoles, but I guess anything can handle any games on 6x4 resolution.

 

[Mrvile]

And Malak, I didn't know Alienware offered the X850PE?

 

[MadEye2]

PArt of the reason for increased performance is because developers are creating code that's optimised single set of chips that is the XBOX. It can't happen on the PC, not unless you can ask a codemonkey to modify the source of your favourite game to bang the most out of your system specs.
It's like the early days of the Amiga - Commodore set some compatability rules that developers must stick too. Some chose to ignore the rules and develop code that will bang the early A500 hardware to it's maximum, but as soon as anyone upgraded or bought a new model of Amiga most of software they made failed to work.

 

[MadEye2]

Doesn't the XBOX have a feature where you can run games at higher resolutions? Would be pointless anyway unless you have a display that can handle them without resorting to interlacing, but still, it can handle higher resolutions can't it?

I don't know which games support it, but my XBOX supports 480p, 720p and 1080i. The games I have are all 480p games however (Halo2, Top Spin and NCAA football)

I am having issues with the YPbPr HD pack however. For some reason using the high bandwidth YPbPr input on my RPTV won't sync (480p or 1080i modes), using my low-bandwidth YPbPr input will sync to 480i, which I can use the TV's onboard line doubler for progressive output. I just got it, so maybe the HD pack only supports 480i? I dunno, I just finished my shift so I'll have some time to play with it now.

Nah, the HD pack is made for progressive scan, and you have to have it or the Monser Cable version to run your xbox to 480p, 720p or 1080i. The trick is you have to go into the dashboard video settings and enable 480p, 720p and 1080i, and you can turn widescreen on there as well.


Also, the xbox cpu isn't a p3, it is a celeron clocked at 133x5.5. It is a celeron as it has half the L2 cache as a p3.

 

[otispunkmeyer]

i think the xbox gpu was a geforce 3 with the extra vertex engine, ala the gf4 which also had twin vertex engines (nfiniteFX 2?) then its mated to a p3 coppermine cpu with half the cache of a proper coppermine cpu. all this is then mushed together with 64mb of ddr.....certainly nothing special

but consoles only need produce a 640x480 image, and seen as everyone with an xbox has the same hardware, the game developers can optimize like crazy without fear of degrading IQ on one product whil increasing Performance on aother product. when they optimize for xbox they dont have to worry about ruining the game for some with different hardware

consoles make it so much easier....u jus have to code for a set piece of hardware, so u can put all ur resources into making it run well on that one piece rather than trying to make it run well on many pieces (ie most ppls computers will differ greatly in GPU and CPU power and memory speed and bandwidth)

tho i have to say Vlave did a very good job making HL2 run on almost any level of hardware.

i thought it was a P3 but with half the cache DISABLED?

 

[canadageek]

xbox definitely has a p3. anand did a little thing a while ago where he put 8? xboxes into one rendering cluster. He mentioned all the specs, plus how to put linux on it

Ordered my alienware the day it was offered. Cheaper than the x800XT, which they stopped offering.

And dude, shrink that sig.

It's actually neither a P3 nor a Celeron... But that description is probably the best.

Actually, if you want to get technical, they need to produce a 480i image, which is 640x480 at 30FPS, interlaced. That's equivalent to 640x480@15FPS (progressive), or 640x320@30FPS (progressive). Couple that with lots of hand-optimized code and lots of little IQ tricks, and yes, it can run a lot of games and make many of them look very good. The free 'antialiasing' (read: blur) you get on a TV helps, too.

The XBox can do 4:3 "720p" (960x720, I believe 60FPS progressive) and 1080i (1920x1080, I think 60FPS interlaced) with a handful of games. A larger number can do 480p (640x480, 30FPS progressive).

 

[Malak]

Not all TV's support that either. I think my tv doesn't go higher than 640x480.

I was affraid of that I enabled my supported modes and widescreen, it just won't sync to 480p or 1080i with my display using the HD pack. I use my low-bandwidth connection(480i component) and set those settings..hooking it up to my high-bandwidth connecton (480p or 1080i) and its out of sync. I use that same connection with my HTPC's and 480p and 1080i work fine, so, looks like the timings are a little off with the XBOX....so apparently no-go.
