Ah sorry wrong thread, then. thanks! wargames posted:760 should be good for now but yeah I'd wait to see the 800 series. Yeah, I told him to wait, but I get the feeling he needs his gaming fix quite soon. Sorry for the derail.

Does anybody have experience altering nvidia bios to allow the hardware 1.21v limit? I'm thinking about going for that again (MSI 780ti) but it very weirdly did not work for me the first time despite doing exactly the same thing I've done on other cards, and the flash reported successful. I did just use someone else's bios (skyn3t?) but I'd have no issue doing it myself if it was feasible

Goons! What's the ETA on 20nm cards? Is it still around January next year? What's the gooncensus - will AMD & nVidia release new (old) cards before then?

Just for fun: GK110 is a 550 mm2 chip at 28 nm. Scaled up to 28 mm feature size, that's a 550 km2 chip, or nearly exactly the size of Guam, including reefs.

Obviously the resistance through the chip that size would be insane so the heat output would be furnace-like, but if it was cooled with liquid helium or something, the resistance would fall and maybe you could have had the future!

Obviously the resistance through the chip that size would be insane so the heat output would be furnace-like, but if it was cooled with liquid helium or something, the resistance would fall and maybe you could have had the future! The big problem here is that, as you scale up the size of a transistor, its switching speed slows. This is because electricity is not instant, and it takes time for electrons to move around. The more electrons you are moving to change the state, the longer that state change takes. Switching faster is based on reducing the number of electrons needed through reduced size, or increasing the flow of electrons through increased voltage. You also run into problems with moving information around, as the timing of information moving between elements on a chip is also strictly controlled, and changing the scale changes the timing. Related to that, is that the longer the timing, the less information you can send in any given time period. A larger chip simply could not move enough information around quickly and reliably. In answer to your question, no, it would not be possible to take any modern chip design and make it on an older process, it wouldn't function.

Obviously the resistance through the chip that size would be insane so the heat output would be furnace-like, but if it was cooled with liquid helium or something, the resistance would fall and maybe you could have had the future! Not even the most powerful supercomputer in the world 20 years ago made of separate CPUs could touch a modern desktop CPU/GPU. For reference a quad core i7 would perform around equal to the 140 GFLOPS figure in Linpack, Ivy Bridge-E would probably beat it and a high end Xeon would crush it. The 290X/780ti do around 5000 GFLOPS single-precision and in the non-gimped DP versions (aka Titan) over 1000 GFLOPS double-precision. Trying to match just the sheer compute performance of one Titan 20 years ago would likely have required hundreds of megawatts and hundreds of thousands of CPUs. quote:In 1993, Sandia National Laboratories installed an Intel XP/S 140 Paragon super- computer, which claimed the No. 1 position on the June 1994 list. With 3,680 processors, the system ran the Linpack benchmark at 143.40 giGflop/s. It was the first massively parallel processor supercom- puter to be indisputably the fastest system in the world.

I wish I knew more semiconductor physics. I plugged in a bunch of flagship CPUs, comparing process node (X-axis) vs. top retail SKU clock rate (Y axis).  Running that trend line back, which is a statistical no-no but whatever, GuamK110 could be hot-clocked up to 4.1 KHz. About 22 MFLOPS single-precision.

I dunno what is happening on that website but nvidia is most certainly going to release something before October 2015. The editing on that "article" is good for a laugh though.

So honest question: Do we eventually get to a resolution point where there's a slight percieved boost in perf because AA / AF and the other little resolution based tweaks no longer become as necessary to run as mathematically detailes/ times per frame?

I believe so yes. Super sampling looks incredible ... even though its technically AA itself I think it shows what a raw higher resolution can do. Then again, a lot of AA has "effects" that have nothing to do with the resolution so maybe not

Yes. If you could render native on a Retina-type HiDPI display, things would be aliased, but the aliasing would be smaller than you could see (in principle - YMMV depending on your eyesight and distance from the display). That said, AF is not AA. Even with perfect rendering with a bajillion times more pixels than you could ever see, you still want anisotropic filtering because it's something totally different and hugely increases visual quality on surfaces that are aren't perfectly perpendicular to the camera (which is pretty much all of them in a game).

The number of GTX 880 rumors seems to be increasing by the day, they seem to be pointing to a late September or October launch at a price under $500. From the specs the performance looks to be slightly above the 780ti and the TDP will likely be somewhat below the current high end cards. http://videocardz.com/51117/exclusive-nvidia-geforce-gtx-880-released-september

I notice Asus has new 6gb gtx780s out. That in itself is boring but they also seem to have used them to debut a new Strix Cooler which they claim is 38% cooler, and is apparently designed to operate in a fanless mode when the GPU is below 65 degrees.

On the subject of the 880, videocardz (yeah I know) has quoted the gigabyte marketing guy slating the release of their GTX 800 G1 Gaming series of cards for late September. Rumour are rumours, but this seems almost semi legit.

Will be really interesting to see how a smaller 880 does against 780ti without the node shrink advantages 580->680 had.
