Friend upgraded his GPU to a 4070 and we're disappointed by the performance

[SugarFreeKnife]

My friends build had a 1050ti before this with a Ryzen 5 3400g, now he upgraded to a 4070. The BIOS had to be updated before the install so he tells me (he went to a local PC shop to get it installed)

We're incredibly disappointed by the performance and were wondering if any of you could help. We suspect the RAM being the issue due to its low speed, but can't be sure if the GPU really is this bottlenecked by the CPU.

The things we've tried:

-Clean driver installs

-Enabling Hardware accelerated GPU scheduling in windows

-Updating windows

-Reinstalling all the games and nvidia programs

At 1080p: (Both Cyberpunk demos had a mix of mostly medium and high with DLSS Performance mode on)

-Cyberpunk 2077 Frame Gen on, RT Off in-game benchmark has average fps be 84, minimum 25, max of 141 (tho in actual gameplay we saw closer to 30-40 in the open     world around 70-90 indoors)

-Cyberpunk Frame Gen off , RT Off in-game benchmark has average fps 51, minimum 13, max 85 (again in actual gameplay it felt significantly lower than the benchmark)
-Riders Republic with ultra settings and AA set at medium the in-game benchmark average fps 43, minimum 7 and max 60

-Fortnite at its Epic preset was very stuttery, jumping up and down between 30 and 60fps, took ages to load in one match.  

-Apex Legends set at all max settings, tripple buffered vsync, reflex+boost enabled, TSAA enabled basically locked at 60

- Spiderman Miles Morales was a complete mess, barely climbing out of 30s at all high RT off 

In all of those examples the CPU was going at all times around 100& while the GPU was chilling around 30-50% utilisation

 

The screenshot was taken before we enabled XMP
PSU is a Corsair CV650

 

So we're looking for your help to explain this odd behaviour, or if its to be expected with the specs

He has a 3400g as his CPU.   He is 100% being held back by it.

 

Good news is his motherboard (B450 Steel Legend) can handle any CPU upgrade, so have him look into the 5800x3d. It's the only one I'd advise pairing with the 4070. 

 

Or the new x3d ones released soon.

The Ryzen 5 3400g is quite the bottleneck for the 4070.
If he upgrades the CPU and get faster RAM, he will see quite a nice improvement

The CPU doesn't support PCIE 4, only PCIE 3.

For example my current CPU is the same but GPU a RX 6650 XT which DOES support PCIE 4 but PCIE 3 is enough for everything for that GPU.

And maybe V-Sync (or G-Sync) is pushing it back, also the CPU being 71°C does mean its (about to) thermal throttle. Maybe you have some stuff running in the background.

Doesn't matter.

 

And 71c is not anywhere near thermal throttling.  Like 20c to go even.

A quad core is bad enough, but on looking it up, 3400G is Zen+ which is... I'd rate it worse than Skylake. A new CPU would be my priority, much more so than the ram.

I'm running a 4070 on the system I'm using to reply. It also only runs PCIe 3. It is not a problem.

I told him to look into that cpu, he checked the performance out on a bottleneck calculator and it said there's still gonna be a 30% bottleneck. So I'm wondering if you know what kind of performance we should expect with the 5800x3d

Yeah don't use the bottleneck calculators.  At all.  Not accurate.

 

Look up YT videos from good reviewers that compare what you're thinking about.  Then make the decision.

 

Or as close to what you have.  Not sure anyone compared the 5800x3d to the 3400g, but they probably did with a 2600 as that is close to the 3400g roughly.

 

 

Or just look at 5800x3d + 4070 in various games to get an idea of performance.

 

TLDR:  It's a fuckton better.  The 5xxx series is a hop skip and jump above the 3xxx series.

The GPU is being bottlenecked by the CPU. Perfect example of this was when I originally built my PC I had a Ryzen 5 5600g paired with my 3080. I significant bottlenecking issues so I upgraded to a Ryzen 7 5800x3D and the jump in performance was astronomical. I would recommend he upgrades his CPU to something newer and more modern.
