Interesting idea - rather than supporting OpenGL and Direct3D, I'd like to see a card that abandons them in favor of a better thought-out API (i.e. general purpose calculation on arbitrarily-sized buffers with arbitrary dimensions and an arbitrary amount of "channels" (or vector/matrix components)). Regardless, I backed it.

Is there a reason why the demo video looks like the cutting edge in 1993? Maybe I'm missing something...

Because the video card is made by a small startup (not much info in their web site, just mentions 2 founders) rather than multi-billion nVidia/Intel?

I think most people will go, great where can i buy the card... oh. The rewards are just the source code. I don't see how this can reach the first goal.

I agree that endusers won't be too happy with this projects, but companies might be, if they need a (not too powerful) video core.

If you're a company you can already license plenty of GPU IPs for use in your SoC (in RTL form or otherwise).

If you look at the various tiers of this kickstarter you can see you'll have to go up to 600k$ to fund a proper ARM SoC 3D IP with AXI support. And since it's a kickstarter you have absolutely no way of knowing what the end product will look like.

I can't imagine any company betting that much money for RTL code with absolutely no warranty about what the end result will look like and if it's going to even fit in your SoC.

And the code being open source is actually not an advantage since it means all other constructors can then integrate the same GPU in their designs for free.

If it gets funded and it ends up working correctly I'm sure many companies will be interested to try and use it in their designs but I really doubt they'd fund it.

The thing is, this isn't really interesting as a card to slap in your desktop PC. I think the market is people who do embedded projects and want something more open than an Adreno or Tegra chip. Those guys will either put this on an FPGA for prototyping, or layout a board for their specific needs and use an ASIC. Either way, the KS itself can't really ship a hardware part to help them.

Based on what little I do know about GPUs, it seems to me that they are aiming for a hardware-fixed pipeline as a first step, and want to move towards general shader based architecture only as a very-very stretched goal. Am I right? If I see it right what is the reason for that? Couldn't they just jump to a modern architecture, instead of following the evolution of the industry? Excuse me for my ignorance, it's possible that even my assumptions are wrong.

OK I'm missing this completely. What problem is this solving ?

I can't believe they have never seen a smartphone recently, so they know what cheapo hardware is capable of pushing nowadays. Yet this exists.

So what is it that is exiting here but fly high over my head ?

Yes, this is not going to work without a card as a reward.

The problem is making an ASIC and going to production will cost much, much, much more than 200k$. At that price you pay for one batch of MPW.

The only way they could do that is if they knew they could market their GPU to a broader audience and sell many units. The problem is I don't see who could be interested in buying a low-perf stand-alone PCI GPU which may very well end up costing more than a TegraII due to the small number of units.

But then it doesn't run any of your existing software and has a tiny market, competing with the various vector processors and FPGAs.
