Radeon X1900 Series @ Anandtech

Anandtech has published their review of the Radeon X1900 Series:
"Take all the clich's used to describe a long overdue event or the unexpected
fulfillment of a promise (hot places freezing, heavy animals soaring through the
air, etc...) and you still couldn't say enough to fully proclaim the news that
ATI has finally properly hard launched a product. That's right, looking around
the internet this morning has provided us with the joyous realization that the
Radeon X1900XT, XTX, and CrossFire parts are available for purchase. We've tried
to keep an eye on the situation and it's been quite easy to see that ATI would
be able to pull it off this time. Some sites started taking preorders earlier in
the week saying their X1900 parts would ship in one to two days, putting the
timeframe right on the mark. There were no missing dongles, no problems with
customs, and ATI told us last week that thousands of parts had already been
delivered to manufacturers.
And if that isn't enough to dance about, ATI
has delivered a hugely powerful part with this launch. The Radeon X1900 series
is no joke, and every card featuring the name is a behemoth. With triple the
pixel shader units of the X1800 XT, and a general increase in supporting
hardware through out the pixel processing engine, ATI's hugely clocked 384
Million transistor GPU is capable of crunching enormous volumes of data very
quickly. Fill rate isn't increased very much because the X1900 series still only
allows 16 pixels to be drawn to the screen per clock cycle, but power is
delivered where it is needed most. With longer and more complex shader programs,
pixels need to stay in the shader engine longer which further shifts the
performance burden from the theoretical maximum fill rate.
NVIDIA would
like us to compare the X1900's increase in ALU (arithmetic logic unit) power to
what they did with the FX 5900 after NV30 tanked. Certainly, increasing the math
power (and increasing memory bandwidth) helped NVIDIA, but fortunately for ATI
the X1900 is not derived from a fundamentally flawed GPU design. The X1800
series are certainly not bad parts, even if they are being completely replaced
by the X1900 in ATI's lineup.
I'll spoil the results and make it clear that
the X1900XT and XTX are hands down the best cards out there right now. But all
positives aside, ATI needed this card to hard launch with good availability,
perform better than anything else, and look good doing it. There have been too
many speed bumps in ATI's way for there to be any room for a slip up on this
launch, and it looks like they've pulled it off. The launch of the X1900 series
not only puts ATI back on top, but (much more importantly) it puts them back in
the game. Let's hope that both ATI and NVIDIA can keep up the good fight. But
let's not forget why we're here. The first thing we are going to do is talk
about what makes the R580 GPU that powers the X1900 series so incredibly good at
what it does"
Whoa. Just as I was beginning to think that ATI was going to slip further and further behind nVidia they come out slugging with this monster. If you've got the bucks, the top of the line ATI card beats out the 7800GTX (yes, even the 512MB flavor) from nVidia on just about every benchmark performed and according to most sources, has better image quality while doing it. I can only think of one word to say: SWEET!
