Would Adding RAM boost FPS on an intergrated graphics card?

[chonkymarmot]

So, I have Ryzen 3 4300G with 8 GB of Ram(single channel) and I was wondering if I were to add another 8 GB of Ram, would this increase FPS? I am mainly interested in playing Dead By Daylight on PC. Currently, it runs around 30 FPS.

Watch youtube videos and see if there's any single vs dual videos for your set up. Dual should boost it but might not get you 60 fps. Might be a ram speed integrated gpu video also.

igpu performance is directly proportional to ram speed (including dual channel)

[Cathulhu]

Yes, but that RAM can only "unlock" the iGPUs potential, not boost it. Adding more RAM than the system and game needs is a waste.
Using faster RAM than the chip can utilize is a waste.

There is a limit on how much you can gain by adding more and faster RAM.

he only has a single 8g dimm, adding another of anything for dual channel will help
but a new faster matching kit will help more

[Cathulhu]

Of course, dualchannel helps a lot. And a matching high performance kit even more.

Double Channel nearly doubles the bandwidth . The performace of iGPU depends on RAM as well , so dual channel could help . I ve found out that despite the bandwidth doubles the performance of the PC increases about 10% , i have a dedicated GPU though but i tested with a chess engine as well .

Regardless , you d better have 16GB RAM , since a part of the RAM is used by the iGPU

edit

a guy achieved 60% increase on R5 3400G , another guy - almost 100%
apparrently for Ryzen iGPU , there should be a tangible difference . Anyways , 16GB is far better and nice to have

Well, my laptop is with Ryzen 5 5500U, 3200MHz CL21 dual channel. Why? Idk. But I tried different iGPU clocks and almost no difference between 1800MHz and 1300MHz which is ≈ 38% lower clock for the same performance. Both tests were made @ 28W TDP

[76561198343548661]

@A&A , not even 10% ?!

[Bad 💀 Motha]

GPU clock alone doesn't make as much difference as you think. Dual Channel RAM at 3200 or 3600 with lower CAS timings helps more for Ryzen onboard iGPU

Higher iGPU clock is only usefull when you have good and effective memory bandwidth. Dropping the clock gives you more power for the CPU. If my iGPU clock is @ 2100MHz, my CPU will perform like FX 8350 or something close to it. If the iGPU is @ 1300 MHz, the CPU's performance is close to I5 10400 and i7 8700, but if the iGPU is idlling, Ryzen 5 5500 is the faster one.

I'd guess you'd see some noticeable improvement by going to dual channel even if you just had 2x4.

[Damian]

I had a specific 5600G APU build to see how good it is.

1. Synced Infinity Clock ratio with your RAM controller
2. Most performance comes from fast Infinity Clock... mine was at 2200mhz
3. Lowering latency on your ram rises minimal FPS and lowers FPS drops
4. OC iGPU and make sure your Mainboard has good SOC VRM

I did 200FPS 1080p@LOW in Valorant... and about 90FPS in Warzone but in 900p@low.

Oh and you need 2x ram sticks (see manual to install it properly in dual channel mode) and make sure you have 2x8GB

[Bad 💀 Motha]

Yea but who the F wants to play good looking games on "Low" visual settings. I'd rather never buy or install the dam game if I have to play them that way. Especially when many games can look worse then a PS3 AAA title game on PC when running 1080p/Low Preset.

If you want to do well with a Ryzen APU like 5600G, it helps to get 2x 16GB. That way you can dedicate 8GB for VRAM

Yolo, GTA5 PC lowest settings 1080P is better than ps3 version.

[Bad 💀 Motha]

Only because for that game it looks alot clearer at 1080p on PC (the PS3 version was only 720p) and the PC version has a bit more details and draw distance then PS3 by default for that particular game.

Anyways you missed my point but whatever. You want your games looking like crap, go right ahead.
