AFOX Readies Single-Slot Radeon HD 7850

At CeBIT, AFOX showed off the industry's first single-slot, air-cooled graphics card based on the Radeon HD 7850 GPU. Carrying the model number AF7850-1024D5S1, AFOX' creation sports a similar cooling assembly as the one on the AF6850-1024D5S1, an HD 6850-based graphics card. The cooler uses a big lateral-flow blower that directs air through a dense aluminum fin-channel array, where heat gets dissipated onto it. Heat is drawn from key components such as the GPU, memory, and VRM, using a vapor-chamber plate.

There's a small catch with AFOX' design, though. The memory amount is halved to 1 GB, although it still sits across a 256-bit wide memory interface. We don't expect a significant performance penalty for that. Further, the memory clock speed is reduced from the reference speed of 1200 MHz to 1125 MHz (4.80 GHz eff. to 4.50 GHz eff.), although the core speed stays the same, at 860 MHz. The display IO is an interesting mix of one dual-link DVI, one full-size HDMI, one mini-DisplayPort, and one full-size DisplayPort.

interesting
can it handle the heat in that form?

I think this is a good idea,because in recent review, the full dual slot 7850 card only reach about 70c under full load,and this card been tuned down,if it does not exceed more than 85c under full load then it should be ok.

i wish high end gpus in the future could be cooled by single slot with acceptable temps.

That's never going to happen. Sure, there's miniaturization of chips, but then there's Moore's law to keep up to.

Pair of these in CrossfireX would remind me of my dual 4850 single slots back in the day :rockout:

CPUs are dropping in power faster than GPUs but the trend is there. Each successive GPU consumes less power than the previous generation. less power consumption, equals less power wasted and less cooling required.

But speedgraphic demand goes up to so really your back at square 1 again.

What is Moore's law got to do with the temperatures?? :eek:

Everything.
Moore's Law states that the amount of transistors on a single die increase and keep increasing, thus making CPUs and GPUs increase in size or in the bast case stay the same (more transistors that decrease in individual size and will compensate each other this way).
So with other words, the growing complexity of GPUs makes their TDP remain at the same level at best.

You sure you are not confusing it with Koomey's Law???:rolleyes:;)

Great little offering for a HTPC crowd, not sure how the loss of memory would affect those with middling gaming on flat panel, but as to video, blu-ray it would provide quality performance in spades.

I say that's their intended thinking.

This is some massive graphics power for a single slot design. Can you imagine GTX480 being a single slot graphics card? :P

NOT for Nvidia! lol :rolleyes:

7770 single slot plz!
7770 looks like a waste of 28nm usage. The card is severely gimped with the 128bit memory interface. AMD really needed to put a 192bit memory interface on it to justify the 28nm gpu on it.

AMD Radeon HD 7770 huge fail at 28nm implementation.

I totally agree, hell even overclocking HD7750's memory brought a massive performance increase.

If the fan can stay quite and the heat under 65*C at stock clocks full load and 70*-76*C moderately overclocked to 960Mhz/1350Mhz, I'll take 2 :)

I can't speak for the 7750's but on the 7850's I totally agree. A moderate OC +OV on my 7850 from 860Mhz/1200Mhz to 960Mhz/1350Mhz +15% OV brought me up 11FPS in 1920x1080 burn in, in Furmark and 15% increase in 3DMark 2011 from 5155 to 6092. And that was MODERATE. It would take a 1050Mhz/1450Mhz +20% no problem. All that from just a little flick of the slider in overdrive. The OCing of AMD is really nice right now in the 7000 series :)
