512MB vidcard enough for these days?


Recommended Posts

And what the recommended output (12V) for an 4850/4770 ?
I don't know exactly, but I can assure you that it's more than your 15A. When I bought an X800XL about three years ago the recommended current was 18A so I suppose it's above 22-24 amps now. A quality 550W unit isn't expensive and it should last you quite a while.

In any case, meet the requirement or proceed at your own risk, that's all I can say.

It's better to have too much than too little, as it would impact other important aspects of the card's specifications.
Well, sure, but I'm just reporting what the benchmarks say. Some games and settings benefit a lot from 1GB, most don't. I wouldn't say 512MB is insufficient generally speaking, it's just not optimal. But again I'd rather have an HD 4870 512MB than an HD 4850 1GB.
I believe most top end cards require about 30 amps on the PCI-E rail, maybe you can get away with 22-25 for a mid range card

not even the most expensive models from antec cannot ouput 30amp, get real..

any recommended antec model? Dr_Asik.

they require 2 connectors, thats how they get the 30 i think.

just checked my 2 GTX280's requires 40amps each

Cosmin, I'll let you know how my friend's Sapphire 4770 turns out. He has been looking to upgrade his ATI HD 2400 for a while but I wasn't sure if his Dell's PSU had enough for a 4770. Luckily, the 4770 has GDDR5 memory, runs extremely cool, short profile (not very long), etc which makes up for the 512mb of memory

Yeah, 30 amps would be the combined current from two or more rails.

I'm not a great reference in PSUs, I use an Antec Trio 550W for my 8800GTS 320MB which has similar requirements, it was cheap and it works well, I think the OCZ Stealth- and GameXStream are excellent values too. In general if you go with a reputable brand and get anything at or above 550W you're set for the next few years. But just in case check out reviews if in doubt.

Thanks , waiting pm with details :)

So, it's important to check the 12V output max in terms of psu's ? I'll go with antec if I'll get a new one (must also fit my case - 80mm fan) , depends on Mystic words :) .. thanks.

Edited by Cosmin

connectors are also important, i got a 1100w PSU was short 2 connectors for the SLI, had to use the Adapters included with 1 of the cards, crap load of other connectors though, good thing its a modular PSU

I should have mentioned he will hopefully have it by Friday (or regretfully Monday, come on UPS). Checking how many amps on the 12V rail is one of the most important things to look for. When I bought my Corsair 660HX, I noticed it had over 50.

Yeah the +12V rail is the most important rating, but in terms of specific amp for specific cards I'm not the reference... This is. :)

I just don't get this thing ;)

It should be fine, more RAM is not always better! I've seen cards with less (but faster) RAM outperform cards with more (slower) RAM. Amount of RAM is only half the equation, you also need decent access speed/interface to be able to get the large amounts of data in and out of it quickly. 512Mb should be more then enough for the time being, it wasn't long ago that it was considered an obscene amount of RAM for a GPU!

    • This one baffles me...so they are creating a museum based around the Ship of Theseus? A museum is supposed to preserve things. It doesn't really work if the conversation goes, "I gazed upon Starry Night the other day, the colours were beautiful!" "Yeah...I didn't expect Godzilla to show up, though." Create a building devoted to displaying AI work, fine. The rainforest idea sounds interesting and I would consider visiting if they pay me a few bucks. But don't call it a museum...
    • >defenders of AI-generated artworks often claim that AI is just a tool It is not. It is the inhuman artist replacement. The human writing the prompt is the employer/manager requesting the work product of the artist -- a supervisory/descriptive job that doesn't carry with it any rights to the copyright of that work product at all. And since AI is not human itself, it can't gain copyright for anything it is asked to regurgitate or hallucinate, so it can't transfer that copyright to the employer/manager/human who asked for the output. This was all legally reaffirmed last year. So, no, while there are AI tools, AI slopware generation is NOT a "tool" in the legal definition of that word.

    • Google is opening the world's first AI museum in Los Angeles by Ivan Jenic Image via: Google Ever since AI image generators went mainstream, the debate over whether AI-generated art is real art hasn't let up. Those who don’t consider AI to be art say that if a machine does the creating and anyone can prompt it, there’s no skill involved, and therefore no art is produced. The counter-argument is equally persistent, as defenders of AI-generated artworks often claim that AI is just a tool, and that every major technological breakthrough, like the camera or the computer, was met with the same skepticism before eventually being accepted as a legitimate creative medium. Google’s position in this debate is clear. Which is no surprise, as the company is investing billions in AI infrastructure. And now, in efforts to encourage people to use its AI even more, Google is opening Dataland on June 20, which it's calling the world's first AI arts museum. Located inside The Grand LA, a Frank Gehry-designed building in Los Angeles, the museum spans 25,000 square feet. The museum is built around a collaboration with media artist Refik Anadol, who has worked with Google since 2016. The inaugural exhibition is called Machine Dreams: Rainforest, and is powered by an AI model trained on “an extensive dataset of the natural world.” It generates 1.2 billion pixels of visuals in real time and reacts to visitors dynamically. The space also generates soundscapes, real-time emotion sensing, and algorithmically produced scents. Image via: Refik Anadol Studio / Google Google says that the museum is powered by its Gemini models, which run on Google Cloud. So, everything is generated inside one of Google’s AI data centers and is streamed to the museum. Alongside the museum opening, Google Arts & Culture is funding an AI Artist Residency, giving four artists $25,000 grants each, along with mentorship from Refik Anadol Studio and access to Google's machine learning tools. Their work will be shown at Dataland and on the Google Arts & Culture website later this year. Google’s AI museum will undoubtedly initiate a fired-up debate on social media, and we can’t wait to see the first reactions. Via: Smithsonian Magazine
