test1:
Score:
1st place: ATI (10 points)
Tied for 3rd place: NVIDIA and XGI (5 points)
Interpretation:
The ATI is the best solution for picture slideshows where there's no 
animation.
test2:
Score:
1st place: ATI (18 points)
2nd place: XGI (13 points)
3rd place: NVIDIA (11 points)
Interpretation:
When it comes to de-interlacing 30 fps content such as TV shows, the ATI 
Radeon X1800XT and XGI Volari 8300 are superior to the GeForce 6600.
test3:
Score:
1st place - XGI (5 points)
3rd place: ATI and NVIDIA (0 points)
Interpretation
When outputting to a television, you will want to have the TV control the 
level of sharpening whenever possible because it takes into account your 
viewing distance and the screen size. All three cards should be great for 
use with a television.
When outputting to a monitor, you will typically need some level of 
sharpening and so the XGI is the best option here.
test4:
Score:
1st place: ATI (10 points)
Tied for 3rd place: NVIDIA and XGI (0 points)
Interpretation
ATI is the first of the big GPU manufacturers to implement noise reduction 
into their DVD playback. This is an important step for PC video enthusiasts. 
Nonetheless, ATI should provide users with the ability to disable any noise 
reduction should a user want to reproduce a "faithful" image from the DVD.
test5:
Score
Tied 3rd place: ATI, NVIDIA, XGI (10 points)
Interpretation
Catalyst 5.13 makes the ATI Radeon X1800 XL a great choice for watching 
movies. NVIDIA and XGI are equally good for playback of DVDs films as well. 
NVIDIA does seem to lock on a fraction of a second earlier (we were unable 
to capture the video output from the ATI to make a true frame by frame 
comparison).
test6:
With Catalyst 5.13, ATI seems to detect all of the known cadences tested by 
the HQV Benchmark. Amazing!
1st place:ATI (35 points)
2nd place: NVIDIA (5 points)
3rd place: XGI (0 points)
Interpretation
If you watch a lot of documentaries that were shot on 30 fps film, or a lot 
of animation, the ATI Radeon X1800 XL with Catalyst 5.13 is the unanimous 
choice. When it comes to unusual cadences, ATI AVIVO completely outclasses 
PureVideo and TrueVideo
test7:
Score:
Tied 2nd: ATI and NVIDIA (15 points)
3rd place: XGI (0 points)
Interpretation
You may see artifacts when watching movies on TV on CNN or MSNBC or during 
the credits sequence with the XGI. You don't see artifacts with the ATI or 
NVIDIA cards under such conditions, but you still lose half your resolution.
FINAL
Total HQV Benchmark Scores
ATI Radeon X1800 XL with Catalyst 5.13: 103
"With Catalyst 5.13, ATI becomes the first PC GPU to break the 100 point 
barrier on the HQV Benchmark DVD. This makes ATI AVIVO an excellent choice 
for DVD playback."
NVIDIA GeForce 6600: 51
"Still going strong after one year, PureVideo represents a good video 
solution that provides great image quality with Hollywood films. Although 
NVIDIA's video deinterlacing was once considered the best among PC solutions 
with XGI and ATI now offering better diagonal interpolation, NVIDIA 
PureVideo is due for an update."
XGI Volari 8300: 38
"The XGI's low score on the benchmark is due to the fact that the Volari 
doesn't handle uncommon scenarios well. But common things are common, and 
for Hollywood movies and pure interlaced content, it's actually just as 
competitive as ATI's AVIVO with the exception of noise reduction and static 
images."
H.264 Acceleration
The Catalyst 5.13 drivers also bring H.264 acceleration as well as the AVIVO 
Video Converter. This means that you'll be able to watch those 
high-definition 1080p trailers from Quicktime with an X1800XL with ease. At 
the moment, we've only had time to do some limited tests with the X1800XL, 
but it seems like H.264 acceleration works very well. We'll have to spend 
some more time in January looking at H.264 decode performance with a wider 
range of CPUs - the dual Opterons I've been using obviously is an atypically 
powerful configuration.
Conclusion
Catalyst 5.13 represents the greatest leap in video quality technology for 
ATI since the original Mach64-VT. It brings sophisticated diagonal 
filtering, basic noise reduction, and the ability to detect unusual 
cadences. ATI marketing told us about "video dominATIon" and we have to 
agree that Catalyst 5.13 brings ATI to the top of the PC video world.
One of the best features of the Catalyst 5.13 is that the software is a free 
upgrade. As long as you have DVD software that supports DXVA, the AVIVO 
video processing will work. Owners of Built by ATI cards obviously have 
access to ATI's Multimedia Center as well. In comparison, PureVideo has 
never been free. It starts off at $20 for the "bronze" edition with basic 
SPDIF out support or 2 channel audio, $30 for the gold version with 5.1 
analog out, and $50 for the platinum version with DTS support. When price 
shopping for a new GPU, if you're going with NVIDIA you need to factor in 
the extra $20 that you wouldn't have to with a built-by-ATI card. Although 
(or because?) NVIDIA PureVideo cannot detect the unusual cadences, its 3:2 
algorithm is faster and is able to lock-onto cadences such as some of the 
anime test clips. ATI believes that NVIDIA PureVideo is faster because the 
PureVideo MPEG-2 decoder is able to provide more information to the GPU. 
Still, we'd certainly prefer that PureVideo be free for NVIDIA owners, at 
least for the GeForce 7 series or that NVIDIA could offer a free DXVA-only 
video processing solution like ATI.
Ten days ago, ATI had the worst video quality on the PC. With this new 
driver, ATI has jumped to the top of the class and then built a nice lead. 
For Hollywood films, ATI edges out NVIDIA's PureVideo. Although the cadence 
detection is faster with NVIDIA, ATI has noise reduction will improve the 
quality of films once the cadence is locked on. In other words, for most 
Hollywood films, ATI will look better for the 2 hours whereas NVIDIA might 
look better for the few seconds after a bad-edit, if such a bad edit exists. 
When it comes to processing interlaced video, ATI now surpasses anything 
that we've seen on the PC with the best implementation of diagonal filtering 
we've seen yet. When it comes to unusual cadence detection, ATI AVIVO has no 
peer in its price range.
There's still room for improvement though. Although ATI and NVIDIA apply a 
region-based motion-adaptive deinterlacing algorithm to high definition 
sources, they do not seem to reliably detect the 3:2 cadence in 
high-definition. Neither ATI nor NVIDIA have the ability to handle mixed 
film/video content with the same skill that some dedicated scalers can. 
Neither ATI nor NVIDIA have advanced detail enhancement or advanced noise 
reduction algorithms that can take picture quality another step forward. 
Even so, with Catalyst 5.13, ATI is making a serious challenge toward the 
dedicated video processors that cost $3000+ and they're doing it as a free 
upgrade. With a fully programmable architecture, there is also room for ATI 
to grow. Companies like Faroudja, Silicon Optix, and Gennum should take 
notice at this new competitor to the market.
The video engineers at ATI deserve a big holiday bonus. They've made a big 
leap in performance and will make Catalyst 5.13 free for download on 
December 22nd. Perhaps the greatest benefit of AVIVO technology is that for 
most of FiringSquad's readers, it's an added bonus. Most people aren't 
buying the X1800XL for video performance alone - they're buying for it for 
the flagship gaming performance.
So what does the future bring? Well, most of what I said 10 days ago still 
applies. XGI still offers a nice product for $50. NVIDIA's PureVideo is just 
as good today as it was 10 days ago, but ATI has tripled their deinterlacing 
performance in those 10 days. NVIDIA must now play catch up with ATI. What 
about ATI? Well, it turns out that this level of deinterlacing performance 
was planned from the get go with the X1K family of GPUs. Now that these 
drivers are about to be released, their engineers are working on enabling 
the next set of technologies for AVIVO to bring even more functionality and 
quality. We can't wait until 2006!
Editors Note: The driver we tested for this article is the same driver ATI 
will be releasing next week, only the final driver will add 
WHQL-certification. ATI is working with Microsoft on WHQL-certification as 
we speak, with an ETA of 12/21.


Real world testing
Although this is actually a 3:2 sequence, and the X1800 was unable to detect 
the appropriate cadence in our real-world test. We saw plenty of jaggies and 
feathering artifacts and our findings were confirmed by ATI. What's 
interesting is that NVIDIA's PureVideo, which only scored 51 points on the 
HQV Benchmark actually does well here (although it occasionally drops the 
resolution). NVIDIA GPUs are able to detect this cadence appropriately and 
for this clip, NVIDIA actually locks onto the cadence faster than even HQV 
solutions. The XGI Volari 8300 was not tested.
Lo sai cosa vuol dire avere dei risultati ottimi in un benchmark 
(pubblicamente disponibile) e *contemporaneamente* avere dei risultati 
disastrosi nei test su comuni video?
Vuol dire che i risultati nel benchmark non sono stati una conseguenza dei 
nuovi driver ma un obiettivo. Chi vuol capire capisca. 

 
ma non dovrebbero chiamarsi 6.1 ? Visto che per ATI il primo numero e' 
l'anno e il secondo il mese
Quando mai esiste un mese 13 :)

Mai, infatti è la prima volta (credo) che viene rilasciata una seconda release 
nello stesso mese ;-)

letta tutta, complimenti ad ati, non tanto per la qualità che si sapeva 
prima o poi arrivasse a questi livelli (l'assoluta programmabilità di r520 
permette questo ed altro) ma anche per il fatto che tutto ciò ati lo offre 
GRATIS al contrario di nvidia....

d'altra parte non mi e' piaciuto per niente il fatto che, al contrario
di quanto annunciato, soltanto l'implementazione delle x1800 di avivo
e' capace di fare 1080p in hardware.
Radeon X1300 owners will be able to get hardware acceleration at up to
480p, X1600 owners get it for 720p, and X1800 owners get full
acceleration at up to 1080p.  ATI did mention that they are working on
bringing those limits down, but that is a time intensive driver and
algorithm optimization process that may or may not happen. 
chi aveva intenzione di buttarsi sulle x1300 come schede economiche
per il video hd si trova fregato.

Ahhh ecco che allora avevo ragione io a dubitare..... E mi chiedevo come fosse 
possibile.... E tutti a rispondermi "Eh ma no, l'unità video è la stessa dalla 
X1300SE alla X1800XT, quindi sono uguali" ecc
Brutta storia questa :-(
In pratica per una soluzione che duri con certezza nel tempo è indispensabile 
andare su una X1800 :-(


Già, mi sa che Blackangel dovrà fare due cose: 1) puntare più in alto e 
2) ricordarsi di quando mi aveva attaccato ferocemente perché avevo 
detto che molto difficilmente le tre fasce di X1000 avrebbero potuto 
offrire le stesse performance video, nella riproduzione dei filmati HD. ;)
Intendiamoci, con un pesante lavoro di lima sul codice, e con qualche 
accettabile compromesso sarà anche possibile vedere un filmato HD 1080p 
sulle X1600 e magari sulle X1300, ma ci vorrà molto tempo e non è detto 
che alla fine si potrà realmente farlo.
p.bes

 per il video hd si trova fregato.
cavolo vero....peccato... ma forse è dovuto al fatto della potenza che ogni 
scheda video può dare... accellerare il 1080p non è così semplice come il 
480i :D


480i :D
esattamente, sono gli shader a lavorare in parallelo per il decoder e
semplicemente nelle 1300 ce ne sono troppo pochi.


 stesse performance video, nella riproduzione dei filmati HD. ;)
beh io aspetto la 1600pro agp sui 120 euro
se anche non ce la fa da sola ad andare a 1080p, vuol dire che la cpu ci 
metterà un pochino di se, mica ho un un celeron 300 mendocino
in ogni caso se, 720p non toccano la cpu, ed è già una cosa buona e 1080p 
non necessitano di un dual core senz'altro come in schede sprovviste di 
accelerazione, la ritengo una soluzione nettamente migliore rispetto alle 
schede incapaci di fornire accelerazione
se una persona ti vuol dare 10 euro e l'altra un calcio nelle balle, è 
chiaro che preferiresti più di 10 euro, ma la preferenza non è che cambi 

 metterà un pochino di se, mica ho un un celeron 300 mendocino
Il problema non è tanto e/o non solo il 1080p, il problema è il 1080*i*.
A meno che Tu non dica "No, il 1080i è cacca, l'interlacciato deve morire, 
l'unico 1080 che mi interessa è il p", nel qual caso mi troveresti pienamente 
d'accordo :-P
Resta sempre aperto il discorso dell'H.264, per cui se non hai la scheda video 
che aiuta ti serve davvero una CPU ultrapotente, specialmente per il 1080
