Lol it's a matter of time, until you buy a GPU and "just" add a CPU and some RAM.

I was kind of hoping doing it that way would let you put big CPU style coolers on the GPU parts with a lot more height than a 1x or 2x expansion slot. If you “folded” the GPU over the CPU to save height I would think that would be worse than today for heat. Maybe I’ve got this backwards. Give up on PCIe, or put it above the rest of the motherboard. The one GPU slot, planar to the motherboard, stays below. Basically m…
> If you “folded” the GPU over the CPU to save height I would think that would be worse than today for heat. Why? Cooling would be far better: the CPU and GPU heatsinks would both face outward from the center and receive clean front-to-rear airflow. Thus, looking down from above: intake air --> [cpu heatsink] exhaust --> [cpu+vrm+ram+chipset] ---------pcb---------- | [gpu heatsink] exhaust --> The power supply and po…

#223All In One liquid coolers are the answer. They were already getting popular in the RTX 3000 series. They make the card thinner and separate out a lot of the weight. They can't cost much more than some of those massive conventional coolers.
AIO coolers do have the tendency to be hit or miss and can seriously impact performance if done incorrectly. If it's out of the box it should probably be fine though but it's not for everyone to replace a GPU cooler and repaste it.
With these power hungry beasts my custom loop, outside of a tiny case (the radiators make the pc look silly small and are connected to it with quick couplings) suddenly makes practical sense instead of just being a "let's see what I can do" project.

#224I liked the new 4090. 12 fans seems reasonable for a sub 1 kW card. Those 2 AC power connectors on the back are a nice innovation. Great benchmark numbers. That they managed to have 21 cards in stock at launch is fantastic!
The 4090 Ti looks fantastic too. Totally worth the risk of fire.

#225The thing I don't get is why are we so damn stuck on towers as the default form factor? It's pretty much masochism to mount a sensitive piece of 8 billon layer circuit board vertically and then hang a bunch of blocks of solid heat conducting metal to it from the side, held on only by a soldered on piece of plastic. Bring back proper desktop cases!
And while we’re at it, let’s bring back rack mount chassis. The rack mount market is appalling at the moment. If you don’t want the volume sales model imported to your region, your stuck getting overpriced models shipped at overpriced rates all the way from the increasingly limited number of manufacturers in china/India/etc, many of which are slowly sliding into overpriced industrial only markets. I bought one at full list price and shipping that had so little care put into it they didn’t even take the protective plastic wrap off the metal subcomponents before slamming them together! All because I wanted a generic 3U chassis to put together a compute node with low profile network cards. I looked at getting an empty chassis to just go open frame drill my own holes and it would have cost more to get a hollow sheet metal tube 3U high than the rack mount unit I bought… ridiculous!

How does latency impact rendering etc?
PCI latency has no impact on rendering, but your card/motherboard may fallback to PCIE3 instead of using PCIE4, in which case filling the cards entire VRAM from RAM could take an extra half-second (slowing the loading of new textures an infinitesimal amount).
Modern engines also do a lot of streaming data to VRAM, rather than loading everything up front. So it’s not necessarily a single delay and could very well impact framerates etc.

Right? Floor space is at an all-time premium with high housing costs. And most people I know have a stack of books/etc. to rise the monitor anyway.
Having a ~140 mm tall desktop case under the monitor doesn't work that well with today's pretty large monitors - it would result in uncomfortable viewing angles. Add to that the often very wide monitor stands. And increased cooling noise because the case comes closer to your ears.
Current monitors can be raised on their stand, maybe future monitors could be lowered in front of whatever they’re on top of?

#228Compare the size of the new air-cooled 40XX cards and the iChill 4090, which is tiny by comparison. The simple answer is just to use liquid cooling if you have a card using 400w. Then all the absurdity just goes away.
The water cooling on my 3090 is heavier than the air cooling for the same card, as you need a coldplate on both sides of the thing to get rid of the heat.
If you give me a lever long enough and a place to stand, I will move the world.
The length of the 3090 with air cooling is what makes it so heavy on the PCIE connector - localized coldplate weight is not an issue.

You can? Both the RTX 3050 and RX 6400 come in single fan form factors not much longer than a PCIE slot. Anything weaker than that is getting beaten by AGUs.
For reference, there used to be low profile cards available barely longer than an AGP slot. For example, here's a low profile Nvidia Gefore4 MX440 (I used to have one of these): https://c1.neweggimages.com/NeweggImage/ProductImage/14-135-... > Anything weaker than that is getting beaten by AGUs. Is AGU the GPU on the CPU thing? Is it not possible (or maybe not profitable) to put something a little more performant tha…
APU*, for accelerated processing unit. Essentially a CPU with integrated graphics, but the graphics cores can also be used for traditional CPU computing if it's not being used for graphics.
They can't put anything bigger because they run into heat, power, and memory limits.

#230Although the idea of the author focus solely on how to fit/support the card in the motherboard, and to provide an existing cooling solution, I actually find it a bit too much, this race to higher performance based on increasingly higher power requirements.
New NVIDIA cards will draw 450W, and, even if you lower that in settings, the all package will still need to be manufactured to support those 450W at various levels.
I wonder what are games doing that require that extra power, seriously. I, personally, would much prefer to slightly have to lower settings (or expect devs to take at least some basic steps to optimize their games) than have a 450W behemoth living inside my computer.
Meaning, 40xx series will be an obvious pass for me. My 1080 Ti is actually still great in almost all aspects.
