G800


<< And here the specs for Matrox G800 go:
Core clock: 200 Mhz
Memory clock: 200 Mhz / 400 Mhz DDR
Render pipelines count: 3
Texturing units count: 3
Fillrate: 600 Mpixels/sec, 1800 Mtexels/sec
Processing speed: 20-30 million triangles/sec
Memory bandwidth: 6.4 Gbytes/sec
Scalable architecture
As far as I remember, previously the memory clock was planned to be 250/500 Mhz DDR. >>



Specter


<< Here are the specs for the next generation board from 3dfx:
Core clock: 200 Mhz
Memory clock: 200 Mhz / 400 Mhz DDR
Render pipelines count: 4
Texturing units count: 4
Fillrate: 800 Mpixels/sec, 3200 Mtexels/sec
Processing speed of Sage, the external T&amp;L unit: 75 (may be 60) million triangles/sec
Memory bandwidth: ? 6.4 Gbytes/sec ?
Scalable architecture. (1 Rampage + 1 Sage)
The specs are given for a basic model (1 Rampage + 1 Sage), but even a basic model looks very impressive. >>



A big day isnt it

[Adul]

Myabe I wait a bit more for my upgrade.

 

[Noriaki]

Nice, now all we need is the NV20 and we can have a big happy family fued over which of hte 3 is better.

 

[interchange]

I vote for the one that doesn't cost me $400.

Oh well, guess I'll wait another year to get rid of these Voodoo2's.

<< I vote for the one that doesn't cost me $400. >>



Don't be silly they won't cost you $400, a V5-6000 is going to be $600 and a GF2 Ultra $500, these guys are the next generation, they have to cost at least $700.

:|:Q:disgust::frown:

 

[Mem]

Now the big question is when are they going to be released? especially Matrox since it should be the first one out(I hope).

 

[Sunner]

Somehow I get the feeling he's just taking guesses(also knows as spreading BS).
Once 3dfx and Matrox announce the chips themselves, Ill believe it, there are far too many people out there who claim to have &quot;reliable sources&quot; to believe stuff like this.

 

[RagingGuardian]

Both units seem pretty impressive. I vote the G800 to be the cheapest. We probably won't see them any time soon anyways.

 

[superbaby]

Those specs for the G800 seem to be a bit low, although I must admit it fills the Matrox trend nicely (mediocore performance with great image quality and a crapload of features). If Matrox ended up being the performance leader that would certainly make Matrox king. I have a feeling that the NV20 is going to blow everything out of the water, including 3dfx.

 

[ragiepew]

and you base that &quot;feeling&quot; on what?... mediocre BS spread by zealots...?

 

[dl]

is it just me or does anyone else think these specs suck! I mean I was expecting a significant increase in power....:|

 

[Deeko]

Take a look at the Rampage specs. That is to Rampage as Voodoo4 is to VSA-100. Just imagine the version with 4 rampage chips and 4 sage chips.....3200mpixel rate, 12800 mtexel rate!! That's insane...and that's effective rates, not assumed rates like the 4800 of the NV20, which is based on 4x overdraw. Even the mainstream version is 1600 mpixel/6400mtexel. That's crazy. Of course, in order for the mtexel rate to be accurate doesn't the game need to be quad-texured? Still....that's nice. Maybe 3dfx will reclaim the throne?

 

[Czar]

Same goes for G800 as for Rampage, multi chip solutions. Great eh

lets just hope we wont start seeing cards like Voodoo5 6000 as a standard

 

[zippy]

I wouldn't be shocked if Matrox used tile based rendering actually.

 

[BFG10K]

Memory bandwidth: 6.4 Gbytes/sec

Is that all? The GF2 Ultra has a 7.3 GB/sec memory bandwidth, up to 8 GB/sec when clocked to 500 MHz (as rated by 4 ns RAM). The Ultra also has a core clock of 250 MHz and RAM speeds between 460 MHz to 500 MHz.

As for fillrate, the Ultra has 1 Gpixels pixel fillrate and 2 Gpixels texel fillrate. Only the Specter has a spec higher than the Ultra: a higher texel fillrate. This will likely be constricted by its inferior memory bandwidth compared to the Ultra.

From the specs you have given me I don't see anything on that list that could be a GF2 Ultra killer, much less an NV20 killer.

 

[Sohcan]

We already know that the mid-range Rampage board will be dual-chip, and the G800 is likely to be the same, so double those pixel and texel fillrate numbers. (1600/6400 mpixels/texels for Rampage, 1200/3600 mpixels/texels for G800).

If Rampage has a similar memory architecture as the V5, the dual-chip board will have 12.8 GB/sec of bandwidth. John Carmack also said a while back that the G800 has eliminated the memory bottleneck problem, probably from tile-based rendering or some sort of hyper-z type method.

Of course, this is all speculation, so I'm not held to anything.

 

[Deeko]

BFG10K, the Rampage specs posted there were the low range product, i.e. the Voodoo4 or the MX. So assuming that they follow what they did with the VSA-100 line, expect double for the mainstream version and quadrupal for the high-end-alomst-no one-will buy(VF 6K/GF2Uish) version. If a chip with a mpixel rate over 1.5x the mtexel rate of another doesn't beat it by a good margin, something is seriously wrong. Don't say memory bandwidth, cause if it's the same as it is with the V5, it will have I think equivilant to 1600MHz effective RAM.(200MHz DDR x 4)

EDIT: Forgot something, if these specs hold true, and 3dfx releases the card in a timely fashion, not only will the card be a GF2U killer easily, it may very well be a NV20 killer. Way I see it, the NV20 has an effective fillrate of 4800 mpixles/sec, assuming there is always 4x overdraw. Well, that's not always gonna happen. In places where there is not alot of overdraw, I expect the Rampage to wreck the NV20, and in places with a lot, I expect the NV20 to be ahead, not by alot though.

 

[Chriz]

Wasn't Rampage the Voodoo 3? I swear around right before or when the Voodoo 3 was released the 3dfx guys said it was the rampage. I mean Rampage has been talked about for over 3 years now (it was talked about BEFORE Napalm which is Voodoo 4/5). I'm pretty sure they're using a different codename now

 

[Packet]

I also disagree with the &quot;Matrox = Medocre 3D with lots of features&quot;

The G400Max was very much on par with the TNT2U

Both are the same generation card

if you compaire a G400Max to a Geforce of cource its going to seem medocre

 

[TheBeast]

Chriz,
voodoo3 was codenamed &quot;avenger&quot;. Rampage is 3dfx's next chip and Sage is the T+L chip.

 

[Soccerman]

first off, I doubt any specs like this (I've always gotten someone saying that these probably aren't real, even though I say this infront of nearly every speculation message based on unproven facts such as this) till I see them!

Second, before you guys start comparing it to the NV20, which we heard from nVidia PR will hit 4.8gpixels/second. what this PROBABLY means is that the PR stretched their legs somewhat.

as DaveB3D so nicely pointed out to me, nVidia's HSR isn't anything near as complicated as Tile Based rendering. it doesn't do a whole other slew of tricks that tile based rendering does to get bandwidth usage down (and effective fillrate UP).

so as DaveB3D pointed out in a previous thread, they got that 4.8gpixels/second out of their ass. why do I think this?

it is most likely that nVidia focused on the bandwidth issue correct? if they did, and kept the same amount of pipes/texture units, they still get a monster increase in performance just from that. however it is also likely that they've shrunk the die as well, giving them a fillrate of about 1.2gigapixels/second if the core is running at 300mhz (good even number no? it probably leaves them a little room for an Ultra version if they need it too I think)

our numbers on the NV20 are this (this is the compressed version) so far:
-1.2gigapixels/second
-2.4gigatexels/second
-6 gig's bandwidth? unknown, but the more the better
-similar features to the NV15
-300mhz
-4 pipes, 2 texture units per pipe

as you can see, it's about the same in terms of features as the above Rampage and G800, however clock speed is somewhat different, which gives us the different fillrates.

as for bandwidth for the G800, we heard one famous person say that they had the bandwidth limit licked, so we might see the G800 perform very well in comparison with the GTS Ultra.

however 3dfx looks to be in a fix when it comes to bandwidth per chip, becuase we have no clue as to what types of bandwidth saving measures they have taken besides adding more chips. these cards could be pretty limited by the RAM (a bit faster then the GTS for each chip, becuase I'm betting that the core and RAM would be synchronized and if the core's at 200mhz, so will the RAM!).

as you can see, I've already analysed this to hell, and until the specs come out, there's really not much else to say, besides cost, and the time that the cards come out.

BTW, that link doesn't work for me at all. it gives me some other webpage called forsite or something like that..
