GTX 970 like performance with a GTX 1070

I am getting framerates very similar to my old GTX 970 SLI setup with my GTX 1070 SLI setup. I used DDU to clean out registry data and it found data for my 970 still being installed with the 1070s. After cleaning and reinstalling drivers, I still get 970 like framerates. Really low GPU usage, nowhere near the refresh rate of my monitor(144Hz). CPU usage is very low, like with my 970s. Tips?

Using i7 980X, 20GB RAM, GTX 1070 SLI

There's a very simple way to prove or disprove what we're telling you. Overclock the processor.

You're still never going to reach the full potential of dual 1070s with that system but performance will scale up.

You have a cpu bottleneck. The 980x is old and is only about as strong as a FX8350. Even an i3 6100 would be an upgrade for you. I recommend a more current i5 or i7.


Low cpu usage is not always an indicator of anything. You have a 6 core i7 but if you're maxing out 2 cores while the other 4 sit idle, your usage % is not going to be very high.

Which is why I asked which games. Some games will hit 2 cores super hard, but if you have a 6 core CPU you'll only get 33% usage. Which you think it low enough, but because it can't use more cores that's all you'll get. You need a better core, or OC it and get a faster frequency. Or both. Until hard details show up it's just a guess.

Modern games like Battlefield 4 that use all 6 cores are nowhere near 100% usage, closer to 25%. Temps are very solid for CPU and GPUs, nothing to be concerned about. High temps are not bottlenecking and I don't have high temps.

CPU upgrade not worth it right now as price to performance ratio hasn't made made proper leap. CPU is not the problem.

One game I ran, did get the GPU usage I was looking for along with programs like 3D Mark, Unigine Heaven, etc. All the others, my GPUs are just sitting there.

this happened a long time ago specifically for gaming, especially for 144hz gaming


and 1070 sli on top.... XD

it cant handle a single 1070 man... cpu + gpu need to be balanced otherwise you get no fps gains



perfect time to jump into a i7 7700k setup

Sorry, I thought you asked a question because you were looking for ideas as to what was wrong. Seeing as you know what it isn't and are unwilling to provide data I'll back off. Good luck in finding info that confirms your theory as to what is happening.

That pic he posted to show his usages is next to worthless it's such a small res I can't make out the numbers.

Try this one:

What documented proof do you have that an older CPU will bottleneck a modern GPU with CPU usage not even 50%? Link?

I have had GPU bottlenecks where the CPU was maxed but never with both CPU and GPU underutilized. Only conflict I could imagine would be the instruction set in the CPU being needed by modern games. Some modern games work correctly with my CPU/GPU setup with almost 100% SLI scaling and GPU usage. Some older games that were released about the time of this CPU which wouldn't need those modern instructions, have the same problem of underutilization.

The one core hitting 86% is the hyperthreading of Core 1. It isn't really a core so that doesn't concern me. Possibly Windows background processes. Total CPU usage is 41%, that is the relevant stat.

That is BF4 not BF1. I have read BF1 still has huge DX 12 SLI issues, as all DX 12 SLI compatible games are having at the moment unless they get patched.

Like I said some games have proper SLI scaling and GPU usage, some don't.

Absolutely disable hyperthreading. That will help for sure. Overclocking would also help a lot.

I would disable hyperthreading, OC as much as possible, and probably remove one of the 1070s. I can't help but feel like the second card is being wasted. A single 1070 with a newish i5 or i7 would be pushing 120-140 fps in BF4 at 1080p easily.

Your core count doesn't mean squat here. What you're bottlenecked by is the low clock speed. Your 980X is roughly 15% slower clock for clock than the i5 2500K. I really hate when people expect me to watch youtube videos in threads but well, here it is. :)

15% slower is 35% more efficiency overall with 50% more processing power from two more cores. 6th/7th gen i7 is a downgrade right now until Intel makes a reasonably priced 6/8 core CPU.

I disabled HT and all that did was lower performance across the board in everything, from boot time to game performance. HT is giving me a huge performance boost.

Here is a pic with HT disabled from BF4, same map and location on the map.

I'm at 1440P 144Hz, not 1080P.

You understand cores aren't additive right? You're using a single core really hard here. The 2500K usage would be identical. You're 15% slower. The video demonstrates the 2500K bottlenecking a single GTX 970 when compared to even a Skylake i3.

I've also seen reports ( anecdotal, no real benchmarks to point to ) that a single GTX 1070 will bottleneck as much as 10% using PCI-E 2.0.

I've seen benchmarks (real benchmarks, not anecdotal) that state the difference between PCI 2.0 and 3.0 ATM is absolutely nothing to a very small percentage which is most likely simply margin of error differences.

The cores are additive in games like BF4 that use all 6. In this scenario, a quad of any kind is a downgrade. It's irrelevant the HT of core one was heavily used at the moment I took that screenshot. All of the CPU is utilized by the game 100%, not just 4 cores. I'm not concerned with older games that are dual/quad core only.

This is a completely ridiculous statement. The i7 6700k is something like 60-65% stronger in single core performance and roughly 40% stronger overall.




I mean you answer your own question in your thread topic. Why else would the 1070 SLI not be an improvement over your old 970 SLI? Your cpu has been the bottleneck the whole time.

Here's some more bubble bursting. IPC and throughput improvements have made your 6 core CPU completely inferior to a modern quad core i7.

http://www.anandtech.com/bench/product/1826?vs=142

The one benchmark that AMD FX chips have traditionally done very well in even against the high end Intel chips in is 7Zip. That's because it likes physical cores more than fast cores. Your 980X loses to an i7 7700K.

Your basic understanding is flawed.
