Keep in mind that comparisons between a X1900XT and a 7800GTx can't be made accurately yet

[Demoth]

The X1900XT for $520 looks pretty decent right now, but just remember that the 7800 series drivers are fully developed and optimized, while the X1900 series drivers are in it's first stages of development. Going by previous generation trends, expect another 25% increase in raw FPS in a month once an optimized driver is released.

As far as OC results, that is anyone's guess. Personally, I doubt the X1900XT will take much beyond getting to a X1900XTX on air. The almost non-differance between the two card makes me suspicious the card is pretty much max as far as core and memory goes for this generation of ATI.

However, driver updates should push the X1900XT above 7800GTx 512 SLI levels.

Too bad crossfire stinks, it's the one flaw in an otherwise excellent ATI round of victory.

Of course by the time ATI "matures" it's drivers the G71 will be out making this thread into a revolving door.

 

[aggressor]

I've heard some bad reports on the fan on the ATI card, though. The GTX line is fast+pretty damn quiet, or at least my EVGA GTX is.

I think for the most part the drivers are ok. True, there may still be some issues and tweaks to work out in the next release, but that's not the main thing holding it back. IMO, the majority of the games benched in most reviews are not designed to take advantage of that much shader throughput. Also, the mem is definitely not clocked anywhere near as far as it can be, since it uses the same mem as the 512gtx, but it's clocked lower. It's a moot point that x1900 barely beats a 512gtx in a 2 year old game like Farcry and HL2, when there are newer games that show much higher gains.

I want prey/QW ET bench results.. plus UT2007

:thumbsup: Yeah 25% seems a bit optimistic- also hopefully after a month or 2 the price will be down to the mid $400 range-this plus some driver gains are gonna put pressure on the G71 release.

Another note- so the G71 comes out in March. From what I've read the G80 may come as soon as June! There is no why I'm going to know when or what to upgrade to....

I'm of the opinion that while the R580 is undoubtedly a good chip, it is currently without a direct performance comparison. Refreshes & Next Gen products should always be faster than the previos products. ATI has the jump start it needed to get market penetration butr when G71 is released and available we'll be able to make proper comparisons. I am I must admit it is strange how the XT & XTX have next to no differences yet they charge a premium for such tiny and frankly pointless clockspeed improvements.

No matter though, i'll be holding out for upgrades until AM2 and G80/R600 for Vista & DX10 compliance.

Prey and QW ET both use the Doom3 engine, so they will probably perform close to the Quake 4 benchmarks, unless ATI gets it's crap together with OpenGL.

another 1900xt thread... there have been many

but yes, drivers will mature. heck im counting on it since i just bought one but it'll be a while. heck even with hacked drivers it performes better then the GTX 256, and most benchies against the 7800512. but i dont mind it losing *sometimes* against a near-vaporware card. never figured why they didnt just change the GTX256's core to the 512's one. same for the GT. ohwell.

next up: G71! should be quite a show.

There is some speculation that the X1900XT cards will only have the 1.26ns ram while the XTX has the 1.1ns ram. For consumers who don't overclock than it's not worth paying the price premium. However, if you like to overclock whatever you get your hands on, than the extra price of the XTX isn't that bad.

Its not so much OpenGl weakness, but rather Atis weakness in stencil shadows. Whoever wins QW ET, will probably be the winner this year or so. (That game is amazing.. i think it will blow away BF2 all together.)

I believe at least a couple reviews yesterday stated that the mem is exactly the same, where is the speculation? I am interested in confirming this since my XT will be here tomorrow.

This architecture is well seasoned by now. I would be very suprised to see another 5-7% performance gains on it. Its not a different architecture than the X18xx series.

I am very impressed with the new part as well as the widespread availability. Kudos to ATI!

Now lets wait for the next Nvidia card to see if Nvidia can do anything interesting.

Dont other games use stencil shadows besides Doom3 engine games? What about games like FEAR, Chaos Theory, COD2? I think the argument may have been true of the r300 cards and their derivatives, but you'd think a modern gpu as forward looking as the r580 would have been designed with volumetric shadows in mind. I'm still thinking it's the OpenGL driver.

There is a guy at xtremesystems who says: "Yup should be child's play already with that card speed.
This one is with cards at only 732/765 (default cooler and default IQ):"
He got 18671 in 3DMark05 on CF.

So there goes overclocking and what's wrong with CF?

Some of the review sites have said the same ram and some have said different. Also some of the members over at XS have been thinking the same thing. Maybe some of the early XTs have the 1.1ns ram but more than likely the later boards will have the cheaper 1.26ns stuff, especially with prices on the XT being fairly low.

We'll have to wait and see when more people start pulling off their hsfs. I'm curious to see whether AMD uses the 1.1ns ram in the XT's. That would be killer if they did.

Yeah same memory- My opinion on the prcing of the XTX is to make people feel like they are getting a great deal, a STEAL when they pay over $500 for the XT model.
(Which I think it is worth $500 for the XT but still, smart marketing...

I just received mine today, I'll list the mem code on mine when I swap hsf's later tonight
