How much faster is 64bit?

[thegoonden]

Last time I tried XP64 and Vista64, nothing worked, none of my software ran and none of my drivers loaded, and my machine seemed downright sluggish.

But the other day, on these very fora, I was told, that everything now works perfectly on either, and should require no special messing around.

While I doubt that in and of itself (I mean the vista64 disc can't have been updated, it's in a drawer), I was wondering about performance.

I'm TOLD 64 is much MUCH faster, and yet the only vista32 score (mine) on the Crysis benching thread, is far far higher than anything from vista 64 (highest 64 score for a quad core and a single GPU is 22FPS, with a much better CPU/GPU than mine, yet I scored over 25).

Could anyone post, or point me too, direct comparisons betwen 32 and 64 bit XP and Vista, on the same exact hardware.

I still don't believe that 64 bit windows is faster (not sure I believe it's working after the way Cubase exploded last time, and as for Grand Prix Legens, the other reason I keep a windows machine, it wouldn't even run).

Well, I was hoping to see proof that it IS faster.
Like I said, the highest scores on this very website are from my own 32 bit machine.


The difference was that going from 16-32 bit provided tangible benefits. More colours, that sort of thing. But I we can already do more colours than can be seen and 16bit is good enough for sound, so 64 really has to be MUCH faster to warrant an upgrade.

Figures?
Anyone?

oh dear.....

Well, OK, a slightly daft example, (silly, AND inaccurate, since really only 24bit is needed).

It just seems to me that since it doesn't /appear/ that a 64bit bus can act as 2x32 ones, the only tangible benefits of 64bit (for now, obviously in time software will be written to take advantage of the better mathematical "headroom" on offer), is the ability to access higher amounts of RAM.

And this business of my machine trouncing[1] better kit running in 64 bit, has me very curious indeed. Doubly so since it uses Dx10, which I though was all very 64bit savvy,


I do have a 64bit OS, as you can see from me sig, and it's scarey quick, but then I never tried that box in pure 32bit, it could just be gentoo going space happy with all that RAM and two cores, when it'd be chuffed enough running on a wristwatch




[1] IS 3fps in the Crysis V.High DX10 test a trouncing?

Sod it, I have a backup of my 32bit vista, maybe I'll try 64 again, with this new service pack, and get my own results, a quick cinebench, Crysis, aquamark, 3dmark06, 1million places of pi should do the trick.

The scores in question are on this very site's standardised crysis benchmarking test (see graphics card forum).


But I think a back to back test on my own hardware will reveal of it's an upgrade or not.

Shall of course post results.
