Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.
Ya, Ya, but can it play Crysis?
lol
Most definitely, son. Most definitely.
LOLOL!!!!!!
4870x2+GTX280?
If this is real, the combined performance of 4870 X2 and GTX 280 combined would be staggering or any other power GPU released to date.
You get the best of both worlds from Nvidia and ATI-- each one complementing their strengths and weaknesses.
Let's hope it's affordable or if any motherboard manufacturer actually implements this.
I feel like such a nerd...knowing thats a math problem involving three gfx cards and not a math problem involving three variables
Not a nerd... the 4870 X2 is just one card. SHAME!
@PCIV:
You've never taken a math class, have you?
I hereby retract my premature statement. It was you who read things correctly, PCIV, and obviously not me.
However the 4870x2 card has two GPUs, which could have led to Cube's statement. I'm going to assume he knows what he was talking about, just used a poor choice of words. Maybe he hit "Add Your Comments" as he realized what was really going on, like I just did.
Yeah...above-linear? Doubtful, unless the chip itself is doing some processing too. Ten bucks says it's going to fail if they're already making claims like that.
Man, it uses that new flux capacitor technology, it goes ahead about 4 seconds in time to see what the game is going to do next.
let's see....
above linear = upconverting
Super linear speedups are theoretically possible when you take into account the increased aggregate memory bandwidth. Such superlinear speedups can be routinely seen in MPP running embarassingly parallel application (though in those cases it is often due to larger aggregate cache size).
I agree with your underlying skepticism, however.
I can't begin to imagine how this works. I mean, most cards are like hardwired to send the output of a lot of GPU functions to the display ports etc.
I reckon the only way is through interfaces like CUDA etc, which will be EXTREMELY inefficient at processing graphics data and returning it back to the CPU instead of outputting it via the display port.
will this be another chip on the motherboard? or a PCI(e) card?
If this proves out, video card fanboy BS will be just that: BS.
Better than linear is hard to achieve but in the CPU world keeping one processor purely in decoding and another in encoding is better than both switching logic between encoding and decoding. Processors are smart and that cache close to the CPU (or GPU in this case) certainly like seeing the same math being done over and over again...
For above linear performance:
Maybe an intelligent routing algorithm which plays to each cards strengths while avoiding its weaknesses? Would that slightly increase the performance of each card and be considered above linear?
Or is it comparing the cards all daisy chained together? (See how this solution works vs the blank screen you get when they are hooked up incorrectly)
I'm not saying it can be done (or done well) in realtime.
Perhaps the above-linear involves caching things that'd have been duplicate efforts?
above linear performance is possible, but only under some special conditions involving scheduling, process priorities, etc. I remember studying this in some comp sci class, but it was so long ago...
Are they the next Bitboys Oy?
Man, I thought I was the only person who still remembered those guys =P
Wasnt this already done with Alienware?
Not sure why you are downrated as it was a legit question.. Alienware did have a board that could do SLI or Crossfire, but it couldn't do both between different cards. It was one or the other.
So is this basically making a cell-processor out of a bunch of old graphics cards?
Too good to be true, my friends. I'm calling vaporware on this one.
Well, you don't have to *call* it vaporware for it to be so. Vaporware just means they have claims not currently backed by demonstrable hardware. That is the case here. Thank you for *calling* it. Also, the sky in New York is currently blue, with some clouds.
If you're smart buy as many stocks as you can of this company when it joins the stock trade.
Wow wow, hold on there a second! You telling me I'm gonna have to deal with both nvidia and ati drivers - meaning double the bugs and double the headaches? :)
You can achieve above-linear speedup in the rare cases where breaking a job to multiple processors allows you to have simpler code for each processor (i.e. split the code such that each card does different functionality that is only part of the unified code) that just fits in the cache, while the single processor version is larger than the cache, causing thrashing and slowdown due to cache misses.
I see this as being particularly environmentally friendly. Think, when you upgrade your video card (which for hardcore gamers is fairly frequently) you will be able to grab the processing power of your new card as well as that of your old one. This is a decent solution to complete obsolescence, whereby your old card might have ended up in the trash.
Yes because when I game that's all I think about...the environment.
Will this be in the form of software, hardware or what? Hopefully if its hardware its like PCI or something, I wanna have all my PCIe spots saved for my outdated cards that can led themselves to a bit of extra power!
M-M-M-m-m-m-m-m-Microstuttering!
It might work for things like CUDA but it will fail at games because of latencies etc
will it blend?
This makes me think of times when Nvidia fans wanted to mix an older 8800 GTS G80 based chip with the newer G90 (or G92 is it?) chip. You can't mix chips. After reading through their site, it will be interesting if this works, but I won't keep my hopes high...
Progression of compatibility is always nice to see.
"It's the above-linear part that particularly makes no sense -- how can you squeeze more power out of cards than is there to begin with?"
Emergent properties! It's the way of the future!
Again, didnt Alienware do this?

Thats right. Thing is, I been around pre the 3DFX days (yes S3 and Virge) and can remember odd bits here and there!
Anyway, Im sure Alienware managed to get Nvidia and ATi cards to work in tandem in an SLI mode.
But whatever, the majority here im sure are joe six pack and only think that Crossfire and SLI is where its at (rolls-eyes)!
The solution is that you could run ether an SLI setup OR crossfire.
You couldn't run two cards of different brands in parallel
"Maybe an intelligent routing algorithm which plays to each cards strengths while avoiding its weaknesses? Would that slightly increase the performance of each card and be considered above linear?"
-rick
I was hoping the same thing, does anyone know when the hell this is going to be ready to do some real benchmarks?
E3 2004: Alienware Video Array and X2
http://uk.gear.ign.com/articles/515/515363p1.html
"The scheme involves two video cards -- they don't have to be identical cards -- and a tertiary PCI card. The outputs from the video cards run to the third card, which sends the signal to your monitor. Basically, each card renders one-half of the scene and then throws it to the array card, which assembles the final image."
There you go.. pure ownage.
Next time low modders, try and validate your info before you mark up/down. ;)
Good memory/research skills.
But, looks like it never came to market. Must not have worked out as well as expected. Not surprised seeing as how ndivia and ati are still having a hard time getting sli/crossfire to scale well, despite having spent tons of time and resources on it. cool that they tried it anyway.
I would like to read more about exactly why it never made it, though.
I would like to see this work on Vista, considering the new WDDM breaks mixed graphics drivers. They could make money off of something that would just let the different cards operate at the same time, let alone together.
ok, so any chipset, any gpu, ...but what kind of monitor does it take?
Didn't ATI already use the Hydra name commercially?
I saw some scepticisem in the comments from people who knows very little about the gaming industry or they are only "just users". Well I saw it in operation and I believe that next year 2009 the market will enjoy the product. I agree with the one who recommanded to buy this company shares when they will be floted.
