ATI X1900 - R580

[tolstoi]

---

Should we say ATI STRIKES BACK?..hmmm

X1900 at a glance:

- R580 chip
- 48 Pixel Shader pipeline
- Higher clock than x1800
- 90nm process
- Avivo and Shader Model 3.0

.................................................. ...................................

ATI secretly released its Silver Bullets material to AIBs this week and the picture of R580 is slowly coming together. R580, or Radeon X1900 as it is called internally, is expected to "launch" in January according to ATI documentation. Unfortunately, ATI's track record has not been spectacular with the last few product launches. ATI's Crossfire chipset "launched" twice, once in June and again in October.

ATI released their Silver Bullets for Radeon X1800 approximately two months before the launch of the card, but it took nearly six weeks after the launch for master card variants of the X1800 to show up on store shelves (and nearly as long for Crossfire motherboards as well).

The Silver Bullets presentation was a little light on details, but did confirm the R580 GPU has 48 pixel shader processors and higher clocks than R520 (a.k.a. Radeon X1800). Radeon X1900 uses a 90nm process also found on Radeon X1800. The internal briefing also confirmed that there will be two separate versions of the card, RX1900CF "Master Card" and RX1900 "Crossfire Ready" card. Like the Radeon X1800 series, you will need at least one master card to enable Crossfire support. Avivo and Shader Model 3.0 will also appear on Radeon X1900.

hahahahaa "Return of the Jedi" muhahahaaa

NVIDIA happens to have an answer to this too, the G71..

Seeing ATI's reputation of successful "paper" launches.. I'm still going for NVIDIA!

[fatsu]

yup me too nvidia all the way

[nitto1320i]

me also. " NVIDIA ALL THE WAY" ~!!! im not saying that ATI are far behind coz its not. hehe. infact they have beaten Vdia's not long ago. the only problem for ati is their drivers which are far behind.

hmmm..let's just see how a 48 pipeline R580 will pair with the 32 pipeline G71 ..anywayz, this is already a boring rivalry..i wonder when will the other vcard manufacturer like the S3 joins the foray.

the way its meant to be played.

Heres a more detailed explaination:

http://theinquirer.net/?article=28341 for ATI's R580
http://theinquirer.net/?article=28227 For Nvidia's G71

ATI will still use 16 pipelines.
Its outlines ATI's use of Pipelines to Pixel Shader ratio which is 3:1. So thats 16 pipelines that process 16 textures with 48 pixel shaders for the upcoming X1900.

Compare that to Nvidia's Current G70 which has a 3:2 ratio, 24 pipelines with 16 pixel shaders. Thats why some games run faster with ATI and some run better on Nvidia.

when daw mo gawas ? late 2006 ?

[tolstoi]

@archille..nice eplanation bai..pero labaw gihapon ang ATI in terms of pixel shader implementation

@Earlz..X1900 is expected to launch this January 2006
