Nice post. FLIPQUAD! Now what does it mean?

Nice post FLIPQUAD! Now what does it mean?

FLIPQUAD is their copyrighted AA method.

I do not know the specifics of it, but it should be some kind of multi-sampling AA method.

Bump-mapping on cell-phones.

On paper this GPU sounds very kick-ass, I want to see how many Vertex Shaders and Pixel Shading ALUs it has (and how well they have been implemented) before I decide.

 

[MightyHedgehog]

Yeah, but how much faster will this sucker drain my cell phone battery?

 

[Panajev2001a]

Yeah, but how much faster will this sucker drain my cell phone battery?

The G40 ? I do not know, but I would not be too worried,

Screens are usually the biggest battery-life drainers.

Cell-phones have no moving parts, small and not very bright screens.

Of course, with normal cell-phones screens I'd think all this power would go very much wasted so for a phone that has a screen that makes the GPU justice, then yes, I'd be a bit worried (still, we have no moving parts, only ROMs and SD cards).

[Dave Long]

Have these guys ever released an actual consumer level card?

 

[Kon Tiki]

THAT on a cell phone??!!

 

[SpoonyBard]

Nope, Bitboys is a vaporware company.

 

[SantaC]

Nope, Bitboys is a vaporware company.

yeah bitboys vs DNF is a classic.

 

[Panajev2001a]

Nope, Bitboys is a vaporware company.

Except not, as they have a NEC license already and other waiting to be announced.

News and press releases

Bitboys Licenses G34 Graphics Processor to NEC Electronics

(Espoo, Finland - August 10th, 2004) Bitboys today announced that it has licensed the new Bitboys G34 graphics processor to NEC Electronics. The Bitboys G34 graphics processor is licensed as an IP (IntellectualProperty) core.

They have silicon now, they are launching chips now.

A classic fight which DNF lost apparently.

and the phantom was a real console too. They have silicon now, they are launching chips now

Does the phantom have support from a company the size of NEC ?

Are you scared for some reason ?

NEC is getting screwed, Bitboys have nothing.

I did explain some stuff, plus you guys already know all the techno-voodoo as you all show in the PS2 vs PSP vs DS vs Xbox threads .



Basically, Bitboys finally is ready with a whole family of GPUs from the very low-end (G10) with a DX7 like GPU with software T&L (done on the host CPU) and fixed-functionality pixel-pipeline (basically the sam rendering features of the GS in the PS2 more or less).

That family supposely scales up till the G40 chip which is their biggest and baddest mofo of a GPU.

Lots of rendering features, Vertex and Pixel Shaders, etc... I do not see any support for HOS (High-Order Surfaces like NURBS, subdivision surfaces, etc... to keep the memory footprint of geoemtry data low and reduce bandwidth requirements).

Explanantion: if I can send the data I need to render 4 Million Vertices in the effective space of 1 Million vertices, I cna go by with a bus to memory which is about 4x smaller and I can save some money.

Unless the G40 has a fast memory attached to it, a lot of its performance might go to waste.

True that Bitboys talk about their "efficient" memory controller (it might be as simple as a normal cross-bar memory controller: instead of one big 128 bits bus you would break it down in say 4x32 bits busses for 4 smaller memory controllers and a switch to regulate access to them from the chip).

They also support, DXT1 (DirectX) compressed textures and Early-Z checks which allow you to reject pixels before they have to be fully rendered (you check their depth before having to pass them through the Pixel Shader) which would increase the efficiency of the GPU as you would spend less time shading unseen/occluded pixels (it depends also on how many pixels per clock this unit can reject: the more, the better).

 

[Panajev2001a]

NEC is getting screwed, Bitboys have nothing.

Shouldn't you leave this judgement to NEC ?

Maybe they have their industry insidurs too .

 

[Blimblim]

Well if they actually finally delivered I'm glad for them. If my memory is correct (and it usually isn't) some of the guys at bitboys are former members (psi and trug) of the PC demo group future crew. They have come a long way since 1993...

Nice. So Sony is not the only Japanese company that never makes mistakes.

 

[Panajev2001a]

Skeptical till the very end... a selective skepticism or real skepticism ?

 

[Oni Jazar]

Bitboys will deliver when they actually deliver a product... to like someone's door.

 

[Seth C]

Skeptical till the very end... a selective skepticism or real skepticism ?

I'd call it realism. This is coming out, and so is Duke Nukem Forever. In both situations, I'll believe it when I see it. "It" being actual product on shelves.

 

[Bregor]

When they produce a product, I'll believe it's real.

 

[Sho Nuff]

I WOULD LIKE TO GO ON RECORD SAYING I ACTUALLY OWN A BITBOYS CARD.

It was a prototype board that I got from Brian Hook back when he was at id. Never ever got it running; hell, the drivers weren't even available. But somewhere in my house there lies an actual authentic functioning (?) piece of Bitboys hardware. Amazing!!!

 

[Dave Long]

But you never got it working. How do you know it's functional? Maybe they just made a mock board and it never ever worked?

Frankly, this is a whole lot of hot air until I see a card sitting on the shelf at Best Buy. NEC's track record isn't much better than Bitboys. A match made in heaven?

I will remember this when you guys talk about HD-DVD .

 

[Lazy8s]

There are some that too closely associate commercial availability with technological availability, ignoring that a product makes it to market on the strength of corporate relations, politics, and pre-existing deals at least as much as its technological merit. Bitboys always had something special even if their product deals kept falling through. And now, their licensing package for this impressive mobile/embedded technology is complete and available for licensing. From the perspective of their market (licensing IP to other semiconductor designers), they've delivered.

Though it's under NDA, it'd be interesting to know the die size, power consumption, and heat dissipation specs for their new solutions.

This line is a mid-generation entry between the cycles of the already-established players in the mobile market like Imagination Technologies, so direct comparisons will be difficult. But Bitboys definitely looks to be as skilled as the top companies in the market.

 

[Shogmaster]

Until I can smack it with my penis, it's just vaporware.
