Poor performance from new Threadripper 1920X

[dean.kavanagh]

I have recently upgraded from the X99 platform, to the X399 platform. My new CPU is a TR 1920X and I have had nothing but problems regarding gaming performance. I never bought this CPU for just gaming, however, from the many benchmarks I have seen from main stream Ryzen, I was expecting quite a bit more! For example, GTA V will not go above the 70-80 fps mark with my GTX 1070, and this is even with no msaa enabled. I get the exact same performance at 1080p with no mssa as I do at 1440p with 2x msaa! GPU usage fluctuates between 50-70% therefore the CPU is clearly holding me back, however, it should not do this as there are benchmarks to show Threadripper hitting at least 100 fps. I have tried various things such as Game mode, new bios, chip set drivers, but to no avail. I don't get how this is happening?

I will post the main parts of my system specs below: 

TR 1920X
16 GB 3000mhz ddr4
GTX 1070
asus prime A x399

Have you observed your CPU speed while gaming?  

[dean.kavanagh]

Yes I have sir, both MSI afterburner and task manager report 3.5 GHz as I have the CPU at stock.

[nick name]

Hmmmm I can try my 2700X @ 3.5GHz to see what FPS is if you want.

[dean.kavanagh]

Yeah, that would be great! What GPU do you have by the way?

[nick name]

1070 ti

[dean.kavanagh]

Nice. 

[nick name]

Here ya go.  

 

1080p

 

I am running RAM @ 3600MHz CL14 w/tight sub timings though.  

[dean.kavanagh]

Thanks mate, you really not have to go to that trouble! As I can see, you are hovering in the 100s as one would expect from Ryzen, whilst I cant seem to get above 80 at all! To add to this, you have a 1070 Ti compared to my 1070 which means that you should be more CPU bound than I am if anything. It just puzzles me even more?

[nick name]

Here is the low FPS spot at 4.25GHz.  It's about 10 - 20 FPS more at the highest.   Sitting in that spot goes from 95 - 110  FPS.

I could try again with my RAM at 3000MHz with looser timings.  If you can tell me what timings you're at maybe the RAM is the answer to your question.  You can use Ryzen Timing Checker to see your RAM timings in Windows.  

[dean.kavanagh]

Thanks.

Does it show timings in ryzen master?

It shows primary so not as helpful.  Ryzen Timing Checker is made by The Stilt and shows EVERYTHING.  Except DRAM voltage.

Hmmmm, GPU usage in his benchmarks is somewhat low too in GTA and his CPU is around 4 Ghz and GPU is almost 2ghz.

I'd say try overclocking your PC within reason and see the results

[dean.kavanagh]

Yeah I appreciate that, however, there is no way a 500mhz OC is going to magically take me to where I should be! I have never hit 100fps at all since switching to this setup, not even looking at the sky! Furthermore, the city area in the benchmark is notoriously extremely CPU intensive, however, he is still hitting 100fps. Also, the reason his usage is extremely low is because he is running at 720p which is ridiculous, but it ensures CPU is at the forefront. An i7 8700k or 9900k would bottleneck a 1080 at that resolution!

I'll downclock my 2700 to 3.5 and report the difference.

I have a 1070 and 3000mhz ram ,so we should be about the same

Yeah 700MHz on the CPU only got me 10-20 FPS.  

 

I do wonder if your subtimings on your RAM were set to something ridiculous by the motherboard.  Some motherboards will set tRFC to a ridiculous value when left on Auto.

actually that's possible i left my ram timings on auto and got about 1620 in cinebench

once I set them manually i got to 1690, not a big jump,but it exists

Isn't there a game mode for Threadripper? 

[dean.kavanagh]

I have that enabled.

[somewittyaccountname]

Ok, I am currently doing 1 run passes ,so these shouldn't be too accurate, but should be used as an extremely rough baseline .city benchmark

3.8 Ghz

AVG mid 80's-mid 90's @ 1080p

GPU Usage:80-90%

with these settings

[somewittyaccountname]

ok, now

3.5 ghz

avg low 60's-mid 70's

with the same settings
