The card is yet again based on the R580 core, the new revision that ATI likes to call R580+. The card works at 650 MHz core but it uses brand new DDR 4 memory working at 2000MHz this time.
The new memory means a faster card but as the clock is still locked at 650MHz it doesn't mean that the performance will blow your brain out, but the price certainly will.
ATI plans to sell this card for $399 in the US and 399 including VAT in Euroland. It is a great price for the board and ATI definitely wants to put even more pressure on Nvidia's 7950GX2 cards that are currently winning the benchmarks.

ATI finally redesigned the cooler and made the heaviest graphic card in its desktop history as there is a lot of copper inside the cooler and it bears a spooky resemblance to the Arctic cooler.
It is really silent - that's what you should care about. You can also overclock the card and it works at 700/2200 MHz as well, and will be totally stable at 689/2178MHz.
These is not much to say about the chip as the only modification we've noted is the support for GDDR 4 memory. The rest is the same as with other R580 cards also known as Radeon X1900 XTX series.
We gave it a try versus Radeon X1900XTX card clocked at 650MHz core and 1550MHz GDDR 3 memory. There was not much of a difference. We tried to overclock and that's when we saw a bit of a delta.
Benchmarketing
We used :
Foxconn C51XE M2aa Nforce 590 SLI motherboard Athlon FX 62 2800 MHz 90 nanometre Windsor core
2x1024 MB DDR2 Corsair CM2X1024-6400C3 memory
Seagate Barracuda 7200.8 400GB SATA NCQ hard drive
Thermaltake Mini Typhoon Athlon 64/X2/FX cooler and Intel CPU's
Silverstone Strider ST60F, 600W ATX 2.0 SATA

We tested our usual set of benchmarks and decided to compare the R580+ based Radeon X1950XTX with its older R580 based Radeon X1900 XTX brother and Sanjin managed to get the card stabile at 689 / 2178 MHz. If we had more time maybe we could tweak some voltages and go even further but this was totally not necessary.

Quake 4 again stays between one and two frames faster. The overclocked card can manage to run six frames faster and that is only the case at 20x15 highest resolution that we test. Quake 4 FSAA 4X and Aniso 8X runs eight frames faster at 16x12 and this is the best case scenario. Radeon X1950XTX overclocked at 689 / 2178 MHz runs ten frames faster but only two frames faster from the default clocked card.
FEAR can show the difference. The new card runs two to three frames faster except at 10x7 where it manages to outperform the old X1900 by seven frames. Overclocked card is three to four frames faster than the default clocked one. The card can not even put a stand when you turn the settings and stays one to three frames faster, while the overclocked card is one to three frames faster than the non overclocked one.
Serious Sam 2 performs almost identical in all cards in the first two resolutions but it manages to run three to six frames faster at the last two resolutions. Overclocked card is six frames faster at 20x15 and that is the biggest difference. Once you turn the HDR on the card runs three to five frames faster than the older one and you gain five to six additional frames by overclocking.
Serious Sam 2 with 4X FSAA and 8X Aniso runs even seven to eight frames faster than the old card. Overclocked card is up to thirteen frames faster than the old card and up to six frames faster than the default clock.
Serious Sam 2 with 4X FSAA and 8X Aniso and HDR makes nine to ten frames difference at first two resolutions and then it narrows to six at 16x12 and finally settles at only three frames difference at 20x15. Even the mightiest ATI card gets to only 30.8 or 32.8 FPS at such a high settings and the highest of 4:3 resolution 2048x1536.
The Radeon X1950XTX is just 400 points faster than the previous card, when you overclock it you gain an additional 1000 more points. In 3Dmark05 there is only a 200 points difference, and even the overclocked card works just 500 faster than the non overclocked one. 3Dmark06 yet again runs just 200 marks faster than with the previous card, while the overclocked card runs 300 points faster. The new card failed to impress even in 3Dmark tests.
In Short
We are not impressed with the X1950XTX card. We expected more but the card failed to meet our expectations. It
is obvious that even for 2048x1536 resolution you don't need that much memory bandwidth. The card is up to seven per
cent faster and that is all you are going to get from it.
At the same time, it is really just a memory upgrade of the existing marchitecture, but we have to mention that the new cooler actually works very silently and keeps the card at an average of between 65 to 70 degrees Celsius.
It will run a little bit faster than the previous card and if you overclock it, it will run faster than that. The great thing about this card is that it will cost just 399 and I think the price and super silent cooler will work on the cards advantage. If you have X1800 generation or older card I can recommend this one. It will make you super happy but don't recommend X1900 supporters to go for this. You still need a master card but this time the master card also works at 650 MHz core and 2000 MHz memory and costs the same, 399 including VAT.
The R600 is the real refresh and we will shortly bring you the scores of X1900XTX versus Nvidia's top Geforce 7950 GX2 dual chip card. ?
