MSI GTX 770 Gaming Testing:

Testing of the MSI GTX 770 Gaming will consist of running it and comparison cards through the OverclockersClub.com suite of games and synthetic benchmarks. This will test the performance against many popular competitors. Comparisons will be made to cards of a range of capabilities to show where each card falls on the performance ladder. The games used are some of today's newest and most popular titles, which should be able to provide an idea of how the cards perform relative to each other.

The system specifications will remain the same throughout the testing. No adjustments will be made to the respective control panels during the testing to approximate the performance the end user can expect with a stock driver installation. I will first test the cards at stock speeds, and then overclocked to see the effects of an increase in clock speed. The cards will be placed in order from highest to lowest performance in each graph to show where they fall by comparison. The NVIDIA comparison cards will be using the 320.14 drivers while AMD-based cards will be using the Catalyst 13.5 beta 2 drivers and latest CAP profile. The results generated in my testing reached by utilizing the latest FCAT tools to illustrate the true picture of the gaming experience. To do so will require a second PC setup to capture the data stream generated by the compared video cards.

Overclocking:

  • MSI GTX 770 Gaming: Core 1254MHz, Memory 1921MHz
  • NVIDIA GTX 770: 1254MHz, Memory 1912MHz

With the MSI GTX 770 Gaming you get a little bit of overclocking built in from the factory with its higher than reference base and boost clock speeds. All that is well and good for the person that wants to just pop the card in and go get their game on. However MSI provides some overhead for the enthusiast who is capable of using the latest tweaking tools, including MSI Afterburner, to grab even more clock speed and thus FPS performance. Again great for the guys who can tweak the card. However let's switch back to the person that wants to just install and game. MSI has a low overhead tool with three presets for this group: Gaming that boosts the clock speed to 1189MHz, Eco that drops the boost clock speed, and Default to bring the MSI GTX 770 back to the standard boost clock speed of 1150MHz.

Using MSI's Afterburner tool to tweak further I increase the voltage as far as possible or 12mv with the temperature target set to 96 °C, boosted the fan speed to 100%, and started raising the clock speed up until the card would fail the stability testing (Unigine Heaven 4.0). At this point the MSI GTX 770 Gaming had reached 1254MHz under a GPU Boost 2.0 boost state. In essence just a short 100MHz boost over the factory core clock speed. The memory from the factory is rated at 7010MHz QDR or 1752MHz. As high as this is I was skeptical that I would be able to gain any more headroom, but the modules seemed to scale well and just kept going until I reached 1921MHz or 7684MHz QDR. That's pretty impressive getting close to an 8000MHz data rate. In all there was not a lot left in the core but the memory boost was a nice surprise.

After looking at what MSI had to offer I took a look at the reference card from NVIDIA just to see how well it would fare without the better cooling and VRM components, and found similar core and memory clock speeds using the same formula outlined above. I was able to hit the same 1254MHz on the core but could only get to 1912MHz on the memory. Still pretty impressive numbers from a GK104 core. Where the two parts differ is in the cooling capabilities at stock speeds.

 

 

 

Maximum Clock Speeds:

Testing for the maximum clock speed consisted of looping Unigine Heaven 4.0 for 30 minutes each to see where the clock speeds failed when pushed. If the clock speed adjustment failed, then the clock speeds and tests were rerun until they passed a full hour of testing.
