The two pictures have grass shadows, softshadows , I think . Iis a DX 9 render feature

There are no newer drivers for a couple of cards in that bench. especially at the time of that bench.
Besides, the x2900's tested now aren't tested with release drivers as well...

Was that one posted already? HIS has 2900XT on their site now

That's sweet.

My two latest cards have been HIS, and I'll probably buy one this time too.

VIVO Cable
HDTV Output cable
DVI to VGA Dongle x 2
DVI to HDMI Dongle x 1
Crossfire™ Cable x 1

Nothing about a 8 pin "converter" though. I hope they'll include one.

Google is your friend.

I know what the black box is, but there was no confirmation till just late last night, that it came with the 2900. Its now on HIS' site. After I posted..

Interested in the 5.1 audio though. I dont understand how they have will audio, with a DVI to HDMI adapter.

audio on the hdmi connector. there is more than enough bandwidth for video + audio on the dvi connector used.

Yes, but there won't be an HDMI connector. There will be a DVI connector with a dongle. And DVI doesn't carry audio. How does the audio signal manage to get as far as the dongle?

[fallguy]

Yes, that is my question. Id rather just have a HDMI connection already. I bought a DVI>HDMI adapter years ago, hurry up an adopt it.

1600x1200 8xmsaa?

It works because HDMI is backwards compatible to DVI, and the graphics card can query device capabillities. So the link will start in "DVI compatibility mode", and when a HDMI capable device is detected the graphics card will add audio output (which is interleaved in the digital stream, so no additional pins are required).

Using a DVI-I connector on the card is the best choice because it can drive DVI single and dual link, HDMI single and dual link, and analog VGA.

Well, I haven't played Stalker at all, but from playing Oblivion, that difference really looks like the difference between HDR and no HDR.

Edit: whatever arnold said!

Return to 64-bit channels is definitely very curious... I presume this means that each pair of chips in a channel is spread over both sides of the board, i.e. back-to-back, instead of sat side-by-side. I say this because the 3-3-2 arrangement looks awkward for 2 (out of the three) side-by-side pairings.

As to explaining the GDDR4 XTX numbers, weren't there rumours of a broken memory controller? If there are no actual XTX boards in the wild now, and all that's out there are old, partly broken prototypes, then...

I can now make out what's going on with the texture unit, working down through it, left-to-right:

• 4x TA unit for vertex or texture fetch (prolly unable to do LOD/Bias, filter-specific calculations?)
• 4x fp32 vertex fetch or fp32 texel fetch
• 4x TF units
• 16x fp32 texel fetch (might be usable for vertex fetches?)
• 4x TA units for filtered texture addressing (cannot be used for vertex fetch addressing)

Hope that's right...

OK, for the worst case, it would seem we're talking about 40 clocks + 200 for DDR = 240 versus 280 in total for the ring bus.

Is that reasonable?

And would you be so kind to compare vs G80 texturing power?

[fellix]

Does that mean, that any order of vertex fetched texture filtering will be done through a Geometry Shader run code?
Much like the lack of FP16 box filtering in R5x0, were custom one have to be coded, then.

At the the same time, R580 too.

You mean 40/80 cycles for propagation across the die and for all the MC related scheduling? According to Bob, the 40 would be too low, right? Where does the 200 come from?

Anyway, if your numbers are reasonable, it's a 16% buffering penalty just for transport.

Being a unified architecture, all kinds of fetch/filter are available to all kinds of shader.

So geometry or vertex or pixel shaders can perform vertex fetches or texture fetches or bilinearly (or better) filtered fetches. On Int8, fp16 or fp32 data formats.

I'm heading out now...

I've been told that HIS is still playing with final clockspeeds. It looks like they're going to clock their HD2900XT a bit higher than reference clocks.

R600 is in full mass production at the moment and retailers should all have their cards at the 14th of May in time for the launch.

The 8800 Ultra doesn't score much more than that on an X6800. Once you get in that range it's all about the CPU.

Could it be that Ati wants to clock it to 750 just to keep it at 225w ? Not many out there with a 8 pin psu.

[Geeforcer]

You know, I for one am getting really tired of the whole "Here some scores with no specks or settings provided" or my new favorite "Here is one screenshot with FRAPS on". IT. IS. SO. POINTLESS.

[fellix]

Well, the NDA is still too heavy to lift.

All I want now is a [very] high-detail shot of the R600 die. Sadly, don't have one of G80.
