ATI PCI-Express Devices Revealed

JohnQ writes "According to Xbitlabs and AnandTech, the specifications for ATI's newest graphics cards have been revealed. Interesting to note is that all of these next generation video cards will run exclusively on the PEG (PCI-Express x16) interface. This does not bode well for those of us who just paid top dollar for the last generation of AGP cards. Read more about the roadmaps on Anandtech and Xbitlabs"

PCI-E about features

[Anonymous Coward]

PCI-E is not about more performance. In fact, a well designed PCI-E card will not show any real deficit in performance vs. an AGP one, provided all other variables are identical.

PCI-E is about making the video processor useful for more than just dumping graphics data. Modern graphics chips are essentially giant geometry calculators, and could be used for far more than they currently are. Due to the fact that PCI-E allows data to be communicated back to the system after it has been processed on the card, this opens up a whole new realm of possibilities. Many 'glitches' in current rendering techniques should dissapear now that the card can relay what the output looks like back to the game driver, allowing it to make on the fly corrections to the image.

PCI-E is all about features, not performance. It should perform like any other interface really, maybe a couple percent faster due to the increased bandwidth, but nothing major. I doubt games will truly begin to take advantage of it for a couple years. Upgrading right now to get PCI-E is ridiculous, however buying a top of the line AGP card at this juncture is equally ridiculous...

AGP/PCI-X is not the most important thing...

[S3D]

For most games/3d-app AGP/PCI-X is not the most important thing. Number of pipelines, vertex processors and GPU clock is defining factor. AGP/PCI-X matter only for applications/games which are streaming (not loading by big blocks) a lot of data from the disk (for example detailed, not patterned, seamless terrain engine), and that is not common in modern games.

Does this mean anything for non-gamers?

[G4from128k]

As a non-gamer I am truly curious about the impact of these latest graphics cards for regular everyday use (spreadsheets, word processing, photoshop, etc.). Do these cards do anything to improve 2-D performance (scrolling, image manipulations, large screen displays?). I would assume that the inproved memory bandwidth helps a few percent, but that all the vertex shaders & pipelines mean little to 2-D office and graphics applications.

I'm just curious.

Of course if you're running OS X or anticipating Longhorn then your whole desktop will be 3d-accelerated. Daft some might say, but why waste all that powerful hardware if it's there? And OS X does look extremely pretty.

Try putting two AGP graphics cards into your computer :)

This is the next evolution in peripherals. Every slot in your PC will be able to take every sort of device you can think of, including the latest and fastest video card(s). Like the old PCI-only days, but with better-than-AGP speed, across the board.

PCI-Express == Vector CoProcessor

[BuildMonkey]

In my lab we're working on surgical simulation including organ physics, cutting, bleeding, etc. We need all the perfromance we can possibly get. The GPU is a monsterously fast parallel vector processing engine, and can be used for non-graphics computation. Asymmetric AGP bandwidth has prevented us from using the GPU as a coprocessor thus far: across the AGP bus you can push data down to the GPU through a firehose, back up through a straw.

AGP was a hack onto PCI. PCI-Express will give us the symmetric bandwidth we need. Yeah!

Re:Cheaper prices

[jridley]

Absolutely. Video cards are like sand in the wind. I'm not a gamer myself, so I get to be amused as my friends pay $500 for a card, then sell it on eBay 12 months later for $200 and buy another $500 card.

I recently pulled a graphics card out of the trash box at work and we putting it into a test box. A friend laughed and said that he had paid several hundred bucks for that "top end" video card about 4 or 5 years ago, and now it wasn't even worth keeping out of the dumpster; any $30 cheapo would whip it these days.

I also don't see how this hurts buyers of the latest AGP cards. It's not like you won't buy a new card when you build a new machine, anyway; by the time you build a new machine that $500 card will be a lamer POS anyway.

Depends on your use...

I actually fail to see why it hurts those of us that did buy the last generation of cards. I needed a video card, this was the best out there (well best bang for the buck) so I bought one. How does this news affect something I did in the past and why would it affect my future? Anyone care to explain?

...but in case your multi-GHz processor will serve your needs just fine for several years, while your AGP card won't last you nearly as long, you'd wish you had an upgrade path, yes?

That being said, not being an FPS freak I've found that by the time I'd like to replace the GFX card, there's also lots of other new things on the mobo, new CPU socket, new memory interface/speeds, RAID / SATA / GB LAN / dual LAN / Firewire / USB2 / Bluetooth / WiFi / PCI-X / whatever to justify upgrading the whole machine.

Or, more to the trend, perhaps what you'd really like is to change form factor from ATX to a mirco-ATX or similar, get one of those mini-PCs.

But, if what you do is gaming, judging by the hours some people I know spend, getting the latest GFX card every six months be "reasonable". Just compare it to how much money other people dump into hobbies like cars or skiing or whatever. If you do it all the time, you want some seriously good equipment even though you'll never "recover" the investment.

And for those, it kinda sucks since they'll need a new computer to go with their spanking new GFX card. On the other hand, the AGP slot has been around for a long long time now, going from 1x->2x->4x->8x. Compared to pretty much every other interface, it's hardly surprising that it's time for some design changes.
