Poor Performance RX 7900 XTX OC

I purchased a AsRock Taichi RX 7900 XTX OC recently and I've been feeling  very let down by it's performance. While it runs synthetic benchmarks just fine and scores on par with similar hardware, even older games feel terrible. The screenshots above are from Stalker SoC with the Stalker Complete Mod. On my 3070 Ti I get well over 100 or more than enough to a point I never even thought about checking the frames. 

I'm running:

AsRock X299 Extreme4

Intel Core i9 9820x @ 4.4

GSkill DDR4 4000 17-17-17-37 XMP2 64GB (16x4)

Corsair 1000i PSU

4 Evo860's in raid0 for games

 

If you look at the 2 screenshots, the one getting 59fps is looking out into the town, and the GPU is only running at 1283 mhz.

The second screenshot, is in a corner looking away when it's running at full speed or close to it.

 

I've tried all of the AMD profiles and combinations, Hyper-RX, Default // Rage mode, OC GPU mode etc.

 

Why is the GPU only running at half speed when it's under load?

 

Prime and OCCT are stable for 10+ minutes temps always under 70 for CPU.

I also have a 7900xtx and I feel you man I'm so disappointed, we both should have gotten 4070 ti supers for cheaper or 4080 super slightly higher....

 

 

We go thru all this too and they didn't even release a Stalker 2 driver like Nvidia did so it's ready day 1....or at all......I get it man trust me many of us get your pain.....

 

Today it's space marines which took a performance nose dive.....its a sad state...just pray for Intel B780 leaks to be true this will force real pressure on AMD, even AMD admits they vsnt compete with Nvidia so they are counting on the peasants and cheapskates to lock down the mid range market well an Intel 780 for $500 that has ray tracing cores and smokes several amd cards at their new b580 $250 price point especially in ray tracing, WILL hurt them bad...and force AMD to support their products....the hardware is fine it's the drivers and that team is out of touch.......

Your CPU has poor single core performance. If you compare the screenshots, you will see that the CPU utilization is the same. My guess is that the game utilizes 1-2 cores, so when you look out in 2nd screenshot, there is a lot more to do, the CPU still feeds GPU at same CPU utilization rate, but there is a lot more to do on CPU, and it cannot keep GPU fully utilized so gpu down clocks.

 

I suggest trying VSR "Virtual Super Resolution" under display to put more processing on the GPU and drive utilization up, then pick higher resolution in game.

 

When I went to 3080 with my 8700k, I found that the CPU could not keep up, and that my previous GPU 20xx? was better or the same in many games. 7900 xtx does not make much sense for your CPU in my opinion.

 

I suggest ignoring the Sgilbert guy as he is spreading his trail of tears in every post it seems.

Stalker is a single threaded application.

 

The single threaded performance isnt that great compared to modern CPU's, but for a game from 2007, and a mod from 2009, it might as well be alien tech.

 

Besides, on the same slow single core performance cpu that I have, with a 3070 ti and all other variables identical, I get 100+.

 

I think I just need to dump this AMD junk on ebay and go back to Nvidia. Now I remember why my last AMD card was a Radeon 8500.

 

Still can't get this whole software thing figured out, can you guys?

 

See ya's in another 20 years, maybe.

Your CPU is cannot keep up with the 7900 xtx, so it simply down clocks and runs at lower rate. NVidia has a setting called "Prefer max performance" which helps prevent gpu down clocking. I do not know if AMD has a similar setting. Like I said, crank the graphics options and resolution to to put more load on the GPU and prevent the down clocking.

I disabled turbo and set my cpu to bclk of 3.3 and absolutely nothing changed.

 

There goes that theory.

 

It's 100% crappy drivers and software just like the last time I tried this junk.

 

Thank you anyways for your help.

 

I think after the 8500 nonsense, and then this sillyness with a $900 card and I'm completely done with 'em.

 

Can't even run a near 20 year old game at 60 FPS, and this is their flagship.

 

How embarrassing.

Considering that AMD uses menu FPS averages in their totals, they probably think they are doing a good job when this telemetry they data-mine from their users reaches them.

 

In realty, it's just people sitting in the menu's changing video options trying to get the games to run smooth and without the horrible latency, lol.

 

Either way, I dropped my 3070 ti back in and fired up BF5 albeit only at 1080P as I prefer a smaller screen for the FPS's I play (really recommend the Alienware AW2523HF if you like high refresh and 1080p btw) and I'm getting nearly the same framerate as you, all settings max'd while actually in game playing with action and such.

 

More importantly, my mouse and keyboard now feel like they are in the same time zone as my PC when gaming and that's pretty important to me.

 

Can't wait for the 50x series cards next year. Hopefully the 7900 will sell by then.

 

(selling for $850 btw. AsRock Taichi White 24 GB OC, maybe 200 hours on it, never touched voltages for overclocking, just used the automated stuff in the AMD crapware a few times for testing. ) cash only Philadelphia area. Feel free to send me a PM! ;o)
