Performance Issues - RX 7900 XTX

Some people like me like to play on ultra 4k with 280 fps / 280 gsynked hertz you know?

Just because you cant does mean others cant too.

Some people just born rich and dont have to work or do anything,just enjoy the good things of life,and asus rog 4090 is one of thise things.

You can forget about that forever till wow2 comes out. With 20+ year old engine thats been upgraded every xpack here and there. There is no way with this engine to pass 150 fps in crowded places. Besides that 5800x3d is best cpu for WoW not 13900k. This ancient engine loves cache.

Which 4K 280hz monitor is it you bought yourself?
And you do know 99% humans cant actually tell the difference above 120Hz
right?
Human sight simply isnt capable of seeing it.

and a 4090 still isnt a gaming GPU, a 4080 Ti would perform better
but hey, gotta have those big numbers!

The 5800x3d is a bit of a gaming beast, but as you mentionm, its all about cache benefit.
Intel 13th gen has a slight lead pretty much everywhere else for gaming (multithread isnt quite as strong but still) when compared to the 5000 series AMD.

The 7000 series AMD are taking that lead back though (which is the 13th Gen true comparison) and its looking like ?Intel are going back to being 1080p competitive gaming niche as their only lead in the gaming world. DDR5 is so brand new atm its burning cash buying a current gen, PCI 5.0 is going to make some incredible changes, particularly with direct access for loading effectively bypassing teh CPU on loading times, but i’d give it a year for the market to properly burn in and RAM to be properly optimised before building anything on teh new platforms.

But you’re also right, WoW is an OLD engine, already pushed to its limits and heavily CPU dominant, buying/building any new system with just WoW as your aim is an exercise in burning cash atm


I did a test with different monitors up to 500hz, and saw a big difference. But hey, we only see 30hz per eye right? Voidsteel is kinda wasting resources tho, as WoW caps out at 200fps.

No way you are getting 280 fps on max graphics. I got a new pc 7950x, 4090 suprim x, 6000mhz ram. If i max out settings i sit at like 140fps and in mythic raid combat like 40 fps

Same issue here. GTX 1070 Ti and i5 6600K 3.5GHz with 16GB RAM. Never had any framerate issues in BfA or SL, but now whenever we pull a big pack of enemies in M+, my frames drop below 30 and it becomes impossible to heal people effectively in high keys.

I already unsubscribed yesterday and I won’t be renewing my subscription in February after it expires if this is still not fixed by then.

Ye games just trash optmised ÂŁ5k pc and still trash fps xD

I also got a 7900 XTX and whilst in FFXIV it got a massive FPS boost, I also had the same / slightly worse FPS than my previous GTX 1080 in Warcraft, two of them infact (as I would swap to the other 1080 when the fan died on the other so I could repair it).

From what I understand WOW CPU usage is quite outdated
 so if you got a 5800x3D the FPS would jump substantially according to benchmarks because of the large L3 cache which games make a lot of use but with newer titles they use more cores, so the advantage is less prevalent / non-existant unless you play old games. In benchmarks a 5800x3D can increase performance by up to 60% in Warcraft, 40% in FFXIV. FFXIV less so because its slightly newer, uses more cores at least more efficiently. Could also be a driver issue, though I had also read 4090 users having the same problem.

I use a 5900x stock, 16GB 3600MHz RAM, but I do have the game playing from a HDD currently.

Well i would guess the ryzen 9 7950x should equal a 5800x3d though

In other games for sure, but even on like Red Dead 2, its like a 10 - 15 FPS difference between a 5900x and 7950x, but those games, even modern wont use that much and tbf the GPU is probs at 100%.

This is whilst killing the world boss with a full 40 man raid, notice how the CPU is capped at 20%, and the GPU drops to 50%, it just cant feed the GPU with enough data. The only hope is a higher clock speed / L3 Cache / WoW gets a CPU usage parse.

Games actually so bad tho, 7950x and 4090 on 5 graphics on mythic dathea and getting 40fps in combat

This isn’t the case. A world boss is limited by either the network and the server (if a lot of people show up) or by the single-core performance of your CPU needed to handle combat world state (you, boss, everyone else, and all the math and order of actions). Combat encounters aren’t GPU intensive.

it’s time that blizz incress the cores last time we had it in BFA since people had same issue with an game once they updated the cores all was working much better!

Not exactly, L3 cache memory is different to number of cores and core speed
 Without specifically looking at eh CPU spec break down I wouldnt be able to tell you how teh L£ memory cache pairs up between the two, but the 5800X3D had an -enormously- high cache size, which wasnt present on higher spec chips either.

Should also point out, im on a 3800XT, 2070 super and i still get over 40 fps on boss fights in raids
and use higher settings, so an element of this isnt just memory cache/CPU grunt, its also the quality and speed of internet connection and how well your system is actually optimised
 compoents should be paired well together and it also goes right down to stuff like VRM on the motherboard, a lot of people dont actually know how to spec a balanced system and just number chase on GPU and CPU, also what other software are you running, which can also impact performance in a big way (such as anti virus nonsense like norton or bullguard for example) or GEForced Exp handling your GPU drivers and settings and junk codecs it loads up
 System configuration isnt just hardware, its software choices too.

Combat encounters still require the GPU to render frames, the CPU needs to feed the GPU frames, if its busy doing other calculations n its sole world thread ie 40 other players doing stuff, its not going to set another thread aside for the GPU, it will work with what its got on that world thread.

I don’t think network affects FPS, internet/network is your just system communicating with the server, worst case if there is “lag” you would get spell delay, but your system will render frames, it just cant accurately place people or what they are doing.

5900x has 64MB L3 Cache, I am kinda amazed a 33% jump in cache for the 5800x3d makes such a huge difference. The new 7900x3D / 7950x3D are set to have 140mb/144mb respectively, thats insane lol.

The L3 cache isn’t shared across all cores, it’s shared per chiplet. So the 5800X3D has 96MB of L3 cache and a single 8 core chiplet whereas the 5900X has 64MB of L3 cache split between the 2 x 6 core chiplets as 32MB each.

So each core on the 5800X3D is backed by 96MB L3 cache but each core on the 5900X is only backed by 32MB of cache, so the X3D really has 3x as much L3 cache per core.

The 7900X3D doesn’t share all the L3 cache either and the 3D cache is only stacked onto one of the two chiplets. So you’ll have one 6 core chiplet with 96MB L3 cache (the normal 32MB + the 64MB 3D cache) and the other 6 core chiplet only has the normal 32MB L3 cache. So the windows task scheduler will have to work out which processes to run on the 96MB L3 chip and which to run on the 32MB L3 chip, similar to how it works with the latest Intel CPU’s and their “performance” and “efficiency” cores.
