Some nice clocks indeed but if you're like me I'm curious to see what it can really do so I installed GPU Tweal II, set a fan profile and proceeded to overclock. Since I'm overclocking I will run the test in OC mode then I'll do a test with it overclocked to the maximum, we all know they leave us some room under the hood so we'll find out how much. I'll skip gaming mode but you can expect a tiny lower score with it since the clocks are slightly lower.
I used the unigine valley gpu stress testing/Benchmark program to test for stability and to see the scores. I have it set to 2560 x 1440 resolution, ultra settings with no antialiasing, this is how I play my games with the NVidia control panel 3d settings set to high quality.
Strix 1070 OC mode
Overclocked to the maximum with GPU Tweak II I was able to get the Boost clock to 2038MHz, over 2.0GHz that surpised me and amazed me at the same time, my matrix platinum 980 TI tops out at 1505MHz. Getting the Memory clock to 9342MHz is nothing more than astounding, that is a 1.34GHz overclock on the memory, the maximum temp was 61c.
There are some nice features with the Strix 1070 and that is two fan headers that are controlled by gpu temp, I think this is a brilliant idea. I'd guess 75% of people liquid cool their cpu including me so now we have the option of having the fans ramp with the gpu instead of the cpu, again just brilliant. It also comes with a free year of Xsplit Gamecaster which is a $99.99 value, that's very generous from Asus other vendors may only give you 6 months.I haven't tried Xsplit yet but I'm going to install it and see what it's all about.
And the Aura lighting? This is one of the coolest features about the Strix 1070, there is lighting in the front on the shroud and a lighted ROG logo on the backplate and you can change it to any color including white !
And Ansel an advanced screenshot program.
I'm very impressed with it's design and how it looks and performance is awesome and has great overclocking potential as you can see, going from OC mode to my overclock is quite a leap, a gain of 7 FPS and 14 max FPS and that shows they let a lot under the hood for overclocking.
Aura is getting an update to sync the Strix 1070/1080 with an ROG motherboard that has Aura lighting. I'll do a performance test with crysis 3, that's still a pretty demanding game and I don't see 111 FPS, I'll post an average.
Ok, so we see performance is astonishing at 1440p let's see what the Strix 1070 can do at 3840 x 2400 resolution which is a little higher than 4k (3840 x 2160).
3840 x 2400, ultra settings, no AA - 64 FPS and was using 4055MB of Vram.
Here's another screenshot of 3840 x 2400, ultra settings, no AA - 50 FPS. It's not the 60 FPS we want but it's still very playable. I wouldn't call this crippling, with Doom the Strix 1070 stands up very well "beyond" 4k resolution.
Next I'll try it with my cpu overclocked and the ram at around 3200MHz and see how much of a performance gain there is.
With my 6700k overclocked to 4.70GHz and ram at 3140MHz there was hardly any gain maybe 1 FPS which wasn't worth overclocking the cpu or ram.
Just for fun let's see what we get with 5120 x 3200 resolution.
5120 x 3200 - 31 FPS, I wasn't expecting 31 FPS and this surprised me, it is playable but it's too choppy for my taste.
OK, enough testing for now I want to go play it and have some fun. I'm enjoying the new Doom game so far, there isn't much story to it but the gameplay is really fun. I haven't come across any big monsters or bosses yet but when I do I'll post a screenshot.
With V-Sync enabled it caps the FPS to my monitors refresh rate of 60Hz. There are two new features with pascal in the NVidia control panel and they are MFAA and Fast Sync.
MFAA = Multi-Frame sampled Antialiasing works by reprogramming coverage sample locations across pixels within the same frame as well as across frames. This has the effect of making the overall sample pattern irregular which eliminates aliasing artifacts.
Fast-Sync = The gpu renders unconstrained similar to V-Sync off but does not tear since frames in excess of the monitors refresh rate are dropped. It delivers latency that is very close to V-Sync off with no tearing.
I was anxious to try this and the latency is better but there is a slight stutter with it, maybe future drivers will fix this.
I thought I'd try out the Xsplit Gamecaster and see how it works and it's pretty easy to use. I already have a YouTube account so I upload my recorded videos there and you can stream to YouTube as well, a capture card is NOT required to stream or record.
Here is some Crysis 3 gameplay with the Strix 1070 recorded with Xsplit Gamecaster.
I'd like to comment on the ROG Strix 1070 fan headers, they work with 3-pin fans as well as pwm fans. In GPU Tweak II you can set the fans to auto, manual or user define. I find user define works very good turning them on to the temperature I set. 60c is the lowest temp I can set for them to kick on.
Auto - The fans kick on low RPM when the temp hits 60c and slowly increase to 100% by the time the temp hits 81c.
Manual - 50% is the lowest I can set them to come on, you can adjust them to your desired fan speed between 50% - 100%.
I'm back with another performance video of the ROG Strix 1070, this time DOOM at 3840 x 2400 resolution, NVidia 3d settings set to performance.
You can see the game settings before the game starts. This is with open gl, xsplit gamecaster doesn't work with vulkan enabled but you can expect another 5-10 FPS with vulkan.
3840 x 2400 Beyond 4k 50 - 60 FPS and is very playable. Xslpit must have trouble keeping up with resolutions higher than 1440p with the pausing and the audio being behind.
So I'm running a Strix 1070 at 2100Mhz stable with 16GB of DDR4 RAM and an intel i5 6500 at stockspeeds, and I can't maintain 60fps on ultra at just 1080p on some games. F1 2016, drops in the high 40's under heavy rain, Just Cause 3 drops in the high 40's during big explosions and Far Cry 3 (yes 3, not 4) dips in the low 50's sometimes. I can list a couple other games where I get drops below 60 despite seeing people with a 980ti or 1070 locked at 60. I'm on max performance and latest drivers and even if I revert to stock ASUS clocks it doesn't change so it's not because my OC is unstable.
