how does a graphics card fit a bus inside it??
Has anyone mentioned vram yet?
It is 2030. The 7070Ti has a 256-bit bus.
The real bus is the friends you make along the way
Cpus having a 128 bit bus on all top end consumer parts since 2001: Ha! Unbroken record intel/amd 🥇
The 290X had 8GB of VRAM in 2013/2014 for a MSRP for ~400 and we’re still selling 8 GB cards for that nowadays 💀
Would a bigger bus improve the card significantly?
It is 2003. The FX 5950 Ultra has a 256-bit bus. It is 1999. The FireGL 1 has a 256-bit bus.
Bus width is only a small part of the equation on bandwidth. DRAM clocking, caches, memory PHY locations, and core fabric bandwidth (how much data gets from one side of the silicon to the other in the fewest cycles) matter more.
But bus width doesn’t tell you anything? The 7800 GTX from 2005 had a 256 bit bus. The Radeon Fury X from 2015 had 4096 bit.
The AMD RX 380 and RX 480 both had 8 gigabyte versions
And both cards were around $200 or less.
ITT people who have no idea what they are talking about.
My 280x had a 384-bit bus
Not to worry. DLSS is here to save the day! Downscaling your image from 4k to 1440 and giving you more frames. Our new enhanced ai makes the image look even better (just don’t do real comparisons, take our word for it). And you can get all this for 3x the price you used to pay for almost the same hardware. Rasterization? No. That’s AMDs thing. We like to find shortcuts to better performance and keep pushing power draws to absurd levels while an rog ally can do quite well on 35 watts.
Do they matter tho
Gtx680 has a 256 bus
I’m very much interested in seeing performance of my 4090 vs a 5080, especially when Vram goes over 16gb
It’s 2017. The 1070 ti has 8gbit gddr5x. It’s 2020 the 3070 ti has 19gbit gddr6x. It’s 2025 the 5070 ti has 28gbit gddr7.
There I fixed it for you. These details are critically important as it shows the bus width isn’t standing still at all.
1070 ti: 256 GB/s
3070 ti: 607 GB/s
5070 ti: 894 GB/s
The amount of VRAM is a way stronger argument.
On the upside in 2027 you will need industrial powercabling with industrial fusing for your new card with 8gb memory….house might melt but thats just the price for being cool.
so the bus width determines how much data you can transfer, right? what determines the speed of the transfers for GPUs? is it VRAM clock?
But the memory itself gets faster, though. There’s a reason why memory bus never really went above 512 bit and even that was always rare and reserved for the highest end of the cards.
Now do 8Gb card, wait what ?
It’s the same reason most consumer motherboards are only dual channel.
It’s more cost/performance efficient to increase ram speed than increase bus width.
4070Ti had a 192-bit bus
That’s the same as the 3060 btw
Man, wonder how many days we can get a streak going of people complaining about NVIDIA even though everyone here still buys them.
So did the 8800GT all the way back in 2007 😉
In the context of gaming industry and graphical cards. The technological advance and leap from 2000s to 2010s is much more significant than from 2010s to the present day.
I’m not saying it’s not there, but play a game made in 2000 and another in 2010 and you’ll notice a difference that’s unfortunately not equal to a game released around 2011 and any game in the modern day.
The lack of tough and fierce competition has lead to this stagnancy. Yet I’m actually optimistic, because it will return soon as many countries are attempting to advance technologically more than ever and that’ll lead to a new brands of graphical cards and new gaming development companies that wants to climb the ladder and attain success.
Why do technical specs matter if the performance is there? If they figured out how to make the performance the same even using a 1-bit bus would it matter? People love to miss the forest for the trees.
The 2070 Super had a 256-bit bus.
The 4070 Super has a 192-bit bus. :\
Who cares!? Why would any mainstream graphics user ever need a floating point number bigger than 256 bit
