Rare GPUs / Unreleased GPUs

We're talking about Larrabee though, this predates any of nVidia's 14nm (16nm?) parts by half a decade at least. (Over a decade if you include the projects that merged into Larrabee, some starting as early as 2006.)
Well I was responding to the part where you said Larrabee wasn't a complete failure, when in fact, at least IMO, it was a total dud. Intel failed to deliver a dGPU for consumers, & then the Knights' Ferry successors couldn't deliver on that compute promise that it initially displayed. All in all, IMO Larrabee was the (bigger) Bulldozer from Intel, especially considering the $ they had.
Also for what it's worth, Knight's Mill was released just last December as a revision of Knight's Landing specifically for AI/ML workloads. I'd hardly call it cancelled. Intel is, as far as we know, still building a new architecture from the ground up to replace what was going to be Knight's Hill.
Speculation at this point in time, although I'd be really interested in their upcoming (d)GPU.

It didn't go to market as a GPU, but it did eventually lead to 3 successful generations of compute cards that still currently reside in supercomputers ranked on the Top500 list. I'd call that a successful product. It was researched, developed, released, and was worth reiterating and improving for subsequent releases. It wasn't just dumped by the wayside and swept under the carpet. Subjective failure, objective limited market success.

Speculation at this point in time,

They have already given some details on what they're doing, here's an interview with the general manager of HPC at Intel. We're well past speculation. We have more information publically available about the exascale architecture than we do about the dGPU project.

what's the deal with the video outputs and Parade dp530 (A0 - ES) DisplayPort controllers? Why are they labeled "Larrabee GPU" if they're not? This one wasn't from an external partner... it even has a bodge wire on it that i haven't seen across all of the 4-5 boards publicly known in the wild

Intel had the hardware made before Knight's Ferry became the focus. Larrabee was cancelled the same month Knight's Ferry was announced. So think of it as Intel had already made these cards to be Larrabee, realized over time that they were better used for compute and simply did the conversion with the existing hardware. If you go back and look at Intel's marketing material for Knight's Ferry they are literally using pictures of Larrabee in their documents because they're the exact same card.

Aubrey Isles (video output), i thought they were all the same card? are you suggesting the LRB1 won't ever function as a GPU and that there's a Larrabee before all of this listed?

"* Knights Ferry / Aubrey Isle / ~LRB1 - mostly a prototype, had some performance gotchas, but did work, and shipped to partners.
* Knights Corner / Xeon Phi / ~LRB2 - the thing we actually shipped in bulk.
* Knights Landing - the new version that is shipping any day now (mid 2016)."

That's what I just said, they're the same card. The physical hardware did not change. Intel showed some stock images of the cards without video outputs, but the reality suggests that all the existing Larrabee prototypes were migrated into the Knight's Ferry project completely intact, and many of those shipped to partners for development.

how can i get mine to display video on its own?

"
i did get the Larrabee to POST, like my system actually boots, but the card itself beeps, 1 long and 3 short



no video output

even with using Above 4G Decoding option, but my motherboard does POST with only the Larrabee in as a VGA adapter

the actual Larrabee card itself has a PC Speaker

159996_upload_2018-9-29_14-22-10.png


i put in a second video card, and the beeps no longer are present on the Larrabee



but the Larrabee isn't appearing in the device manager, and it's not appearing in the BIOS as linked in



the larrabee seems to be alive though... maybe just needs an old motherboard



if i remove the 2nd video card the larrabee gives 1 long and 3 short beeps again "

What I know about getting them to work is you can't. The software environment that Intel used to demo them as 3D accelerators was supposedly archived and is entirely unavailable outside of the company, at least that's the last I heard. It should still appear in the device manager as an available device though, so if it's not then your card might be having problems. I have yet to see anyone successfully utilize the card as the primary display adapter outside of Intel.

My ASUS X99-DELUXE doesn't even show the card as linked in at any speed on the PCIe Bus, but i see the speed listed for the M.2 NVMe at x4 and also I see the speed for my Vega 64.


Do you think i'd see any possible luck with an older motherboard known compatible with Xeon Phis (first gen?) what i mean is... having the Larrabee at least POST to display 2D on it's own
 
What is this?

Hmm, how do you think it might be worth?
mmmeeehhhhh =(

Sad that the first question about this find is "how much $$$ can I get for it?" vs "how do I post some sweet benchmarks and find out how many pixels this historically significant card can push?"

we'll never know, cause ebay fodder =(

At least give some background info man! How did you come upon this card?

Hell yeah, the original Terascale!
It sucked, but man it was sexy in that red.
 

And here's why those entries now exist: meet the Radeon HD 2950 Pro.

It's basically just a Radeon HD 3850, and reports as exactly such in all applications. It's clocked at 600MHz core and memory, which translates to 594MHz actual in 3D applications. Perfectly stable in both Windows 10 and 7 with legacy drivers, and AMD GPU Clock Tool can in fact alter the clocks where other programs can't (including AMD Overdrive). Here's the 3DMark Vantage results, stock and "overclocked".

Awesome cards. I have an odd obesession with the HD 2000 series. I still have more to collect, but have quite a few now. I am also the individual that purchased the 2900 XTX up above. It’s a MAC version, as shown by the PCI bracket. I assume it was sold or tested in an OEM environment? I don’t know much about the MAC versions of these cards. I’ll have more info once I get it. The part number is different vs. the other 2900 XTX’s found on this site.

i need more pics and info on this 2900 XTX, afaik none are Mac editions they all have the same bracket except some have no handle.

use in gpu-Z, validate and upload bios
 
I was thinking that, but couldn't find any conclusive benchmark data to support a comment. Maybe you found something I haven't?
4670 is better, 2x more memory and faster clocks
less rops but more TMUs

The 3850 is a good amount faster than the 4670. The 256-bit memory on the 3850 vs the 128-bit on the 4670 makes a big difference.
