Info om kommende MONSTER-grafikkort fra ATI
Grafikkort af Webmaster tirsdag den 10 oktober 2000 kl. 15:23 [ Grafikkort ]
Det ser ud til, at grafikkortproducenten ATI ikke ligger på den lade side. Allerede nu understøtter ATIs RADEON grafikkort mange flere 3D egenskaber end Nvidias GeForce2. Og det ser ud til, at der er noget endnu større end Radeon på vej fra ATI - nemlig Radeon MAXX og Radeon 2. Radeon MAXX svarer til 2 x Radeon på et grafikkort (2 processorer, 128MB ram, dobbelt båndbredde, dobbelt fillrate, dobbelt af alt). Eftersom Radeon allerede nu har langt bedre DVD-afspilningsteknikker indbygget end GeForce2, så vil Radeon MAXX og Radeon 2 være kort, som vil konkurrere direkte med GeForce3 (NV20). Lad derfor være med at købe GeForce2 Ultra nu, som du kan se nedenfor, så ankommer Radeon MAXX, Radeon 2 og GeForce 3 om 1 - 2 måneder. Og kr. 5000 er væsentlig bedre brugt på GeForce3 eller Radeon MAXX end på GeForce 2 Ultra (GeForce 2 Ultra fra Creative Labs koster nemlig kr. 4.995,00, jf. www.edbpriser.dk)

Info fra www.rage3d.com:

RADEON MAXX - 128MB, to be released in late Octoberearly November.

RADEON II - 2 times faster than RADEON, full DX8 part, programmable TCL engine, to be announced during Comdex Fall 2000 (Nov. 13 - 17) and will be available in December.

RADEON II MAXX - Dual RADEON II setup based on ATIs AFR technology, to be released in Spring 2001, 3 months after RADEON II release.

RADEON PRO - 4 times faster than RADEON, 400mhz core, 0.15m, enhanced rendering architecture, will be available in the summer of 2001.

Aces Hardware (www.aceshardware.com) har lavet dette resume:

Videocard - DUAL TEXTURE Fillrate - Memory bandwidth - Available

GeForce2 Ultra - 1000 Megapixels/s - 7.4 GB/s - This month?
Voodoo5 6000 - 732 Megapixels/s - 11.7 GB/s - December 2000?
Radeon MAXX - 732 Megapixels/s - 11.7 GB/s - December 2000?
Radeon2 - 732 Megapixels/s - ? - December 2000?
Radeon2 MAXX - 1470 Megapixels/s - ? - Spring 2001
Geforce3 - 1200 Megapixels/s - ? - Christmas 2000

Jeg kan ikke finde Aces Hardwares referencer for GeForce3 postulatet. Tværtimod har jeg set fillrateangivelser på 4800 Megatexels, og personligt tror jeg mere på, at dette tal dækker over 1600 Megapixels x 3 teksturer end 1200 Megapixels x 4 teksturer. Men vi få se, et er i hvert fald næsten sikkert: GeForce3 bliver meget hurtigere og bedre end nuværende GeForce2. Polygonantallet fra GeForce 3 estimeres til 150 mill./s, mens ATI Radeon MAXX vil kunne klare 60 mill./s (sammenlign med GeForce DDR = 15 mill./s, GeForce 2 = 25 mill/s, GeForce 2 Ultra = 30 mill/s, Radeon = 30 mill/s).

Både Radeon MAXX og Voodoo5 6000 kommer med 183 MHz ram og processor. Da Radeon standard og Voodoo5 5500 kommer med 166MHz ram og processor, er der her lidt ekstra til godteposen.

Jeg fandt lige lige ekstra NV20 (GeForce3) info på Aces Hardwares forum. Dette er skrevet af "General Lee D. Mented" (fra http://www.aceshardware.com/board/general/read.php?message_id=20007786)

There's been several details leaked about NV20 (Nvidia's next chip, I don't think it's officially Geforce 3. The only other name I've heard is "Toy Story on a Chip"). It may be rumors but rumors aren't always unfounded.

Poly rate: 150Mpoly/sec

Possible? Yes.

Probable? Yes.

Explanation: a "poly" means triangle usually since you want this number to be high. Technically you can make a triangle with 2 new vertices if you have at least one vertex already in existance by connecting to the existing geometry. Hence, if NV20 has a 300mhz clockspeed (probable), and transforms 1 vertex per cycle (probable), 150Mpoly/sec. How to get all those polys over AGP? You don't, this chip is also rumored to have hardware curved surface support, hence most of these polys will be constructed locally from high level geometry. Note this also matches the Xbox specs floating around.

Pixel rate: 1200Mpixel/sec

Possible? Yes

Probable? Yes

Explanation: Obviously Nvidia wants their next product to beat their current product in every possible way (Geforce2 ultra). This means exceeding 1000Mpixel/sec. Also 300mhz x 4 pipelines = 1200Mpixel/sec. This reinforces the 300mhz expected clockspeed.

Textel rate: 4800Mtextel/sec

Possible: yes but with a hefty price tag

Probable: unknown given current memory situation

Explanation: Nvidia is rumored to be moving to FOUR textures per unit on this chipset (gee maybe they'll dig up my name entry for GeForce and call it Nvidia Quad Damage), as they anticipate newer engines (read Doom3) will use more texture passes (and according to Carmack they're right). 4 textures per pixel implies 4x 1200Mpixel/sec = 4800Mtextel/sec. Can they deliver this? I have no idea. It'd take some massive memory subsystem work or a bigass onboard cache.

Memory bandwidth: 19.2GB/sec ?

Possible: yes, but expensive as hell!

Probable: not unless they want 4 digits in the price or have an ace in the hole

Explanation: 4800Mtextel/sec 32bits per textel implies 19.2GB/sec. This would take a 256bit bus running with 300mhz DDR (600mhz) effective to deliver it. Or a 512bit bus at 150mhz DDR, which is the only currently feasible system I could think of, outside of embedded memory. One would make the pin count huge, driving up board cost. The other would make the die size huge, driving up chip cost. I can't see a way around this problem given current technology. However Nvidia is fairly good about delivering promises.

Other features:

Tile rendering? Maybe. It's been hinted that this upcoming chip will have "zero or near zero overdraw". That usually means a tile architechure but maybe there's other ways to do it via more agressive poly culling.

Onboard compression? Putting compression in the actual pixel rendering stage would buy alot of memory bandwidth outside the chip. Possibly the 4:1 change from the current hardware, but only with compressed textures. Given how crappy S3TC is I pray this isn't the case or they use a different algorithm. It's a possible solution as it cuts memory demand back to 4.8GB/sec for 4:1 textures.

Shaders. Definately more shaders. And better support. Vertex shaders will be added (see DX8 previews), which will allow really neat stuff like say damage geometry instead of just damage skins, that's generated from force calculated from impacts. Or really nice flowing water and fabrics.

box is still for Fall 2001, and is supposedly going to use "an NV25 graphics core capable of 150Mpoly/sec". This will probably not be the expensive highend shipping product at the time. It will probably be a scaled down version of the revised core on a newer process. Think Geforce vs Geforce2 MX. What's the MX's specs like compared to the origional? What do you think highend NV20 at shipping this winter vs budget NV25 next fall will be like? =)

Also developers need a platform to start testing games on if Xbox wants to launch with any titles. This requires 2 things: 1. DirectX 8, which is due to ship soon I believe, and 2. Hardware capable of approximating the performance and behavior of the Xbox engine. See NV20. NV20 will probably also be the only card to be able to run DX8's new TrueHAL mode where everything is direct to hardware. This means hardware vertex and pixel shaders as well as transform and light. It really needs to ship about 9-12 months ahead of the system launch for a proper development cycle to occur, which would be by the end of the year if Microsoft is still on a september target. =)

I say expect a simultaneous NV20 and DirectX 8 announcement (and IMMEDIATE chip availability in volume, i.e. it's been stockpiled thanks to TSMC doing well on the fab side) sometime this month. This would give a fairly short OEM ramp time (less if OEMs are currently designing under NDA) of 4-6 weeks, which could still put us on either side of thanksgiving weekend (November 23rd to 26th for you non-US readers) to see cards on shelves.

Nuvel, en lille opdatering. Radeon MAXX udkommer ikke, dette grafikkort er blevet aflyst. Radeon2 vil sandsynligvis blive annonceret juni 2001 og udgivet juli-august 2001. Så ATI's planer om 6mdr's produktionscyklus er indtil videre helt gået i vasken. Så hvis Nvidia atter påbegynder 6 mdr's produktionscyklus, så holder ATI måske ikke længe... men med 3DFX ude af billedet, og Matrox, som stadig fumler med G800, så har Nvidia ikke megen konkurrence på grafikkortmarkedet - så hvorfor skynde sig...
