4070 Super on a Gen 3 PCIe Lane

[Emillio]

So, I have a very old motherboard and cpu which is the msi b350m mortar and a ryzen 5 1600 from way back in 2017. I wanna upgrade my gpu first to an rtx 4070 super. I will upgrade the rest of the components later. My question is, how much performance difference for an rtx 4070 super running with a gen 3 vs gen 4 speed of pcie? is it more than 10%? and also i have a 650 bronze psu from antec is is it capable of handling it?

Don't have a test for the 4070S, but it should have similarly low impact to the 4090:

It's mostly the lower end cards which only have PCIe x8 or even x4 with low VRAM that are affected.

Considering your PC is running with a 1600, I wouldn’t worry about PCIE bottlenecks at all because your CPU has a bigger impact on performance. Just make sure when you upgrade your CPU, you get a gen 4 or 5 motherboard.

 

You could get away with 650W for now, but when you get a better CPU you’ll likely need something like 750 or 850W depending on what you get

My 550w PSU with a 4070 super and 7600x should probably be upgraded

i might upgrade to 12400f or 12600kf is that possible? i check power supply calculator from cooler master and the result is 511 watts total consumption.

actually, is it safe to upgrade to 40 series now? because i think 50 series will come soon?

cpu wise drop in a 5700x3d to get rid of the cpu bottleneck cause the 1600 is nowhere near fast enough to run a 4070s

 

psu should be fine considering these chips draw <150w

waste of money platform hopping for worse performance than a 200$ 5700x3d

Based on rumors could be this year, could be start off the next year. But likely the high end stuff (e.g. 5090) will come first and that will be very expensive.

 

Based on rumors AMDs new cards should launch around the same time and could be fairly affordable this time around.

On what planet does he need an 850w or even 750w PSU for a 4070?

 

Can we stop trying to make people spend money.

 

His motherboard will support a 5700X3D / 5800X3D with the latest bios and providing his psu is of decent quality a 650w is plenty for a 5800X3D + 4070 Super combo.

 

Gen 3 PCIE vs Gen 4 PCIE account for about 3% difference on a 4090.... it's even less of a difference on a 4070 super.

 

OP don't buy a 12th series intel , Buy a 5600X3D / 5700X3D or 5800X3D when you have the money and keep your current mobo and psu.

i want to change my motherboard too. i want to change to the one that support gen 4 pcie x16. the reason i go with 12 gen intel is because its kinda cheap here in my country, indonesia and support ddr4 because i didnt want to change my ram yet. i was thinking to change to 5600x but then i was wondering if i gotta change my motherboard soon, wouldn't it be better to go to the newer platform like the 1700 or am5. am5 is good but i need to change to ddr5 so 12400f is kinda compelling to me.

There is nearly zero difference between pcie gen 3 x 16 and pcie gen 4 x 16.

 

5800X3D will poop all over the 12400f....it's not even close.

 

Then where do you go from there? 13th and 14th gen have issues and most wouldn't recommend them.
