This thread actually reminds me of the old school computers which used IDE hard-drives using UDMA which is what transfered everything on the ATA controller.
I had an old motherboard and old hard-drive using something such as UDMA-33 which meant max transfer speed of 33.3MH/s.
So I decided to upgrade to a new motherboard and new harddrive which supported UDMA-100 because I assumed my files will open 3x as fast. Was it the result? No.
Basically there was almost no difference in transfer speeds between the 2 different motherboards and hard-drives. I did a few benchmarks and the results were almost identical.
Took me a while to realise that this was more for a setup where you got more than 1 hard-drive and you are using the drives simultaneously, but for a single drive it didn't make a difference.
Kind of like buying a Ferrari that can go 200MPH while the speed limit is 50MPH.
Topic: PCIE gen 4 will it have an effect in crypto mining? (Read 305 times)
The PCI-E extenders can run at PCIE 1.0 X1 with no hashrate drop. What makes you think that you will benefit from PCIE 4.0? 
In current technology and algorithm yes, it will not benefit from it, but what I am saying is that in the future if developers adapt and make improvments can this technology be beneficial?
It will be beneficial to the future generation of graphic cards, this new technology opens up a whole new world for graphic cards producers like Nvidia and Amd.We should hear an official statement from these companies in order to know more where the benefits will be.

The benefits of PCIE 4 come into play with stuff like offloading heavy computation to an FPGA/ASIC type device (like the Acorn)...since you can now offload heavy compute tasks twice as fast between the GPU and secondary device through the PCIE bus. So for heavy memory bound algorithms like most of the GPU centric ones you can have the GPU do what its good at and handle the large memory intensive parts of the algorithm, and then offload the compute heavy rounds to a FPGA/ASIC device. This will significantly reduce the power consumption of the GPU and give a hash rate boost, and the speed ups will be compounded due to the bandwidth increases between the GPU and secondary device over PCIE 4.
So in theory the hashrate can be boosted twice with less power consumption in the GPUs or secondary devices, though it will depend on case to case basis of the users. The only thing that I am worried about is the motherboard integrity as they already mentioned that it will draw more power up to 15w so that the chipset can supply power to the PCIE, specially that in mining the rigs are working 24/7.

Wouldn't FPGA bitstreams benefit from it? I believe that was one of the limiting factors. Also, I suspect it would be good for any rendering tasks... So the render-farms out there might consider upgrading.

I am not 100% sure this is correct but I remember back in late 2016 early 2017 when ZEC was first released and Claymore released a miner for it, the GPUs which used the x16 slot were faster than x8 which was faster than x4 and x1. And the conclusion drawn was that Claymore coded the algo to do some compute with the CPU for every cycle.
I think the reason why Pcie 1.0 X1 has no drop than a Pcie 3.0 x16 slot is because it doesn't communicate with the CPU too frequently. So the Pcie 4.0 probably wouldn't have any boosts compared to Pcie 3.0 currently out.
However with gaming is very different because the GPU communicates much more frequently with the CPU and maybe for gaming it might have an effect.
I am well aware in the gaming side of things and that most of GPUs right now cannot even maximize the PCIE gen 3 bandwith. What I am here for is that your thoughts in the future of this technogy. Will developers take advantage of it to make a new algorithm that uses such transfer speeds much like in raid configuration? As in data computing in data center such speeds will benefit from such tech.

After the AMD keynote in Computex motherboard manufacturers unveiled their new x570 chipset for the Ryzen 3rd gen. This chipset boasts the new PCIE gen 4 that have 16 GT/s per lane, which means that it will have a 256 GT/s per 16 slot, which is too much for the current GPUs.
Though some enthusiast mentioned that memory and data transfers benefits form this new tech I am wondering if this is also true for crypto mining as even ASIC mining uses the PCIE lanes.
That means if the single PCIE lane for gen 4 will have doubled result on GT/s from PCIE 3.0. But I don't think there will be a lot of gap on its performance when you are trying to create a comparison between a single lane of PCIE 4.0 that have 16 GT/s with 2 PCIE 3.0 lane that can carry 16GT/s too. I'm personally feeling doubt about what enthusiast said about that. Though some enthusiast mentioned that memory and data transfers benefits form this new tech I am wondering if this is also true for crypto mining as even ASIC mining uses the PCIE lanes.
