Performance, Value And Conclusion
Benchmarks
Veteran Tom’s readers probably won't be surprised by these charts. Comparing the Asus 970 Pro Gaming/Aura to both sets of Gigabyte data shows no big anomalies during PCMark 8 or the majority of Sandra synthetics. However, for some reason the Sandra Cryptography benchmark demonstrates 10% slower bandwidth with the Gigabyte DDR3-1866MHz configuration compared with the Asus product. The results are similar in the memory bandwidth test, which just goes to show that tweaking memory for the sake of tweaking memory can sometimes backfire.
Video editing benchmarks picked no favorites among the four workloads and three data sets, although the Gigabyte motherboard did pull off a three second win on Handbrake. The Adobe suite looks pretty consistent across the samples, except that After Effects' memory requirements clearly handicapped the 8GB configuration (more on this in my previous article).
The fully populated Gigabyte GA-970-Gaming SLI configuration did manage to finish 11 seconds ahead of the Asus motherboard in the Adobe Acrobat workload, but the 8GB configuration was only two seconds faster. We saw mixed results in the compression tests, where the Asus motherboard scored a win with 7-zip, while the Gigabyte board took the win in the WinZip CPU workload.
Gaming benchmarks were not all that interesting, but in 3DMark11 the Gigabyte board did take quite a beating in the physics score. For regular Firestrike, both boards are running neck-and-neck, and Firestrike Extreme continues to level the playing field. It might be time to upgrade my graphics card.
Fallout 4 did show a larger variation in frame rate when compared to the Asus motherboard however. Running from Hangman’s Alley west in my 50 second clip showed a maximum frame rate increase of 3 fps, a minimum frame rate decrease of 2 fps, and an average framerate increase of 2 fps. Though it might not look like a lot, that’s nearly a 10 percent swing on each of those metrics.
Battlefield 4 was much more consistent, where only fractions of an fps separated the averages and maxes between the boards. Note: I only included the 1600MHz data here, since all other data shows that memory configuration would only slightly impact performance.
Power, Temperature And Efficiency
One of the biggest differentiators among motherboard designs is efficiency. I’ve seen several small ITX boards pack a punch while drawing little power, and I’ve seen high(er) end boards draw gobs of power with little to show for it. This Gigabyte motherboard is a little of both. While idle, this board draws anywhere between 5W and 11W more than the similar Asus 970 sample. However, as we begin to increase the load on the processor, clearly the Asus has the advantage by up to a whopping 70W. Even when the processor is a smaller part of the equation, FurMark makes the Gigabyte GA-970-Gaming SLI draw up to 19W more power.
However, the AMD FX-8350 installed on the Gigabyte motherboard appears to generate 6ºC less heat than the Asus installation when fully populated. I can’t really explain the DDR3-1866MHz data, but it’s safe to say that in that configuration we are running in a similar environment as we are for the Asus motherboard. As for the regulators, I’m pleased to report that these heatsinks are quite up to the task. Compared to those on the MSI 970 Gaming board, these heatsinks are bottom shelf, but they are effective at keeping my overclocked regulator temperatures down to 75ºC.
If power and temperatures didn’t make it quite clear, hopefully the relative efficiency chart can make it crystal clear. Because it draws nearly 70W less power and performs just as well, if not better, than the competition, the Asus 970 Pro Gaming/Aura clearly wins the efficiency battle. What’s more interesting is that the Gigabyte board continues to struggle when placed into the DDR3-1866MHz configuration.
Conclusion
Taking all the synthetics and gaming benchmarks into account, clearly performance differences are negligible and the largest spread in the data is around three percentage points. The Gigabyte GA-970-Gaming SLI has a slight advantage in the gaming benchmarks, but the Asus 970 pulls ahead with the synthetics.
Now it boils down to value. With performance on the majority of the benchmarks roughly equal, price is king. At publication time, the Gigabyte wins with a sub-$100 price tag. The Asus retails for nearly $20 more and currently has a rebate available that drops the difference to $10, which still can’t compete when you examine raw performance. From a feature perspective, both products provide similar solutions, but the Gigabyte does seem to make some concessions to help curb costs, although there is some good swag in the box.
Overall, the Gigabyte is a good motherboard for someone making the small step into the AMD gaming scene or for a user who wants M.2 but can’t wait for Zen/AM4. The platform provides average performance, great overall overclocking stability, but leaves out some tuning ability and memory compatibility where other vendors shine.
