GTX 780 proformance

[spartin503]

Does anyone know of/have the proformance difference between the 780 with GPU Boost 2.0 water cooled vs air cooled with the recferance cooler?

I think it's still a bit too early for that. People are most likely still waiting for either the card or waterblock to arrive.

Probably, the same difference a reference cooler Titan is to a water cooled one. Still, it depends on the silicon lottery on how good of an overclocker the GPU you get is. There's also ambient temps to take into account since GPU Boost 2.0 uses temps as a basis for its overclocking.

I have a stable 1201mhz on the core, reference cooler, any more than that and it will crash in games, I could run Heaven 4.0 fine at 1241 core but gaming was unstable, I have yet to encounter any kind of freezing in benchmarks or games with the current core clock of 1201, I have not touched the memory.

 

I recorded the process in the Heaven 4.0 environment I was overclocking with, I ended as stated above able to loop for as long as wanted/run benchmarks at 1241mhz boost frequency, but that proved to be unstable while gaming, I have dropped the offset to +175 now.

 

The voltage is set to +38mV, which is as far as the card will let you go, and at max load, 1201mhz core it sits at ~62C with 100% fan, In terms of actual performance, water cooling isn't going to improve it for me, as the reference cooler seems to have the temperature perfectly under control at the maximum I have been able to stabilize my core at. It would however make it quieter.

 

Below I will paste the statistics I gathered.

 

 

 

Heaven 4.0 Bench, Extreme Preset, GTX 780 (320.18 WHQL Driver) REFERENCE COOLER. ASUS P8Z77 V-Pro - Intel 3570K @ 4.2Ghz (1.12v) - Corsair Vengeance 1.5v 1600mhz 2x4GB DIMMS.


Stock Clocks Initial Bench (No + offset) - 992mhz Boost @1.14v - SCORE = 1630 - FPS = 65.7 - Min FPS = 25.4 - Max FPS = 148.8

First OC Increment of 80mhz (+80 Offset) - 1071mhz Boost @1.14v - SCORE = 1724 - FPS = 68.4 - Min FPS = 26.5 - Max FPS = 151.8

Second OC Increment of 25mhz (+105 offset) - 1097mhz Boost @1.14v - SCORE = 1747 - FPS = 69.4 - Min FPS = 26.2 - Max FPS = 153.0

Third OC Increment of 45mhz (+150 offset) - 1136mhz Boost @1.14v - SCORE = 1795 - FPS = 71.3 - Min FPS = 28.0 - Max FPS = 154.6

Fourth OC Increment of 45mhz (+195 offset) - 1175mhz Boost@1.14v - SCORE = 1834 - FPS = 72.8 - Min FPS = 28.4 - Max FPS = 155.3

Fifth OC Increment of 30mhz (+225 offset) - 1215mhz Boost @1.14v - CRASH @ 1215 boost @1.14v - adjust core voltage to +38mV

Re Run - Core Voltage 1200mV (+220 offset) - 1241mhz Boost - SCORE = 1922 - FPS = 76.3 - Min FPS = 28.7 - Max FPS = 157.5

Crash was seen at max Vcore @+225 offset, Max Achievable CORE OC stands at +220 offset @1200mV @1241mhz.
Final run of the benchmark shows the performance acheived.

Stock Core Boost Clock - SCORE = 1630 - FPS = 65.7
Overclocked Core Boost Clock - SCORE = 1922 - FPS = 76.3

     14% Performance Increase Achieved.

As can be seen here, the offset doesn't set the exact clock, it moves the range of potential clocks, you will see that I acheived a higher boost speed with a lower offset, just by increasing the voltage.

 

It is a tiny bit unpredicable in this manner.

Pretty nice increase you've got there. I got about just a tad higher on my water cooled Titans, around 16%. I did have to flash a custom VBIOS to achieve it.

 

What are your ambient temps? Mine is at 23C.

What are your ambient temps? Mine is at 23C.

I'm in England, and the few days since I've owned the card have been quite mild, it's about 20C in here, the side is off my case.

With the side on the case, and my fan profile set up to reduce the noise, I allow the card to settle at ~75C with about 80% fan.

2 Titans, very nice indeed, it looks like you received 2 good pieces of silicon!

Don't forget, my actual performance will be a tiny bit lower than +14% as I had to take the boost clock down to 1201mhz, so -40mhz in order to remain stable in games.

It would be nice it Heaven stable meant game stable but unfortunately that's not the case.

 

My idle temperature, it is in the mid 40s.
