I'm just a small time guy working a normal job as a physician assistant. My passion is building PCs and testing/reviewing PC hardware.

Hello everyone. Will here and today, I am comparing the nVidia GTX 1070 Ti, the Zotac Mini in this case, against the AMD Radeon RX Vega 56 by Gigabyte. Both cards are good cards and offer great performance but at a premium price. So, without more delay, let’s do this.

Test System

For testing, I went with my Intel Core i7-7700K system. The CPU is overclocked to 4.9GHz on a 120mm AIO liquid cooler. The system sports 16GB of DDR4 RAM clocked at 2900MHz. These components are “housed” on the MSI Z270 Tomahawk motherboard and games were loaded onto the Corsair MP500 M.2 NVME SSD. Powering the system is an EVGA 550B, 550 watt power supply. I used a standard 1080p computer monitor by BenQ with a 75Hz refresh rate for testing.

Comparing Zotac GTX 1070 Ti Mini against Gigabyte Radeon RX Vega 56

Tested Video Cards and Methods of Testing

The cards tested here are the Radeon RX Vega 56 Founder’s edition and a Zotac GTX 1070 Ti mini. The Radeon RX Vega 56 offers 3584 stream processors and 8GB of HBM2 video RAM with a 2048-bit memory interface. The card comes clocked at 1156MHz base frequency and 1471MHz boost frequency. The Zotac GTX 1070 Ti min offers 2432 CUDA cores on the Pascal architecture and 8GB of GDDR5 Video RAM and a 256-bit memory interface. The GTX 1070 Ti is clocked at 1607MHz base and 1683MHz boost clock.

In the benchmark testing, I chose an assortment of 7 games, all of which are relatively new to the market, specifically released within the past 3 months, with the exception of Prey, which was released in May 2017. This assortment of games allows us to see how certain games prefer one card over the other. Both cards were tested at stock settings with no overclocking at my level. Keep in mind, the Zotac GTX 1070 Ti mini graphics card is factory overclocked which should automatically give it a slight advantage. At any rate, here are the benchmarks.

Call of Duty: World War II

First up, we have the newest of the bunch, Call of Duty: WWII. This game was run at 1080p on Ultra Quality. The GTX 1070 Ti came away with a clear performance win here with a 1% low of 112 FPS and 134 maximum FPS while the RX Vega 56 pumped out just 73 FPS at a 1% low and a maximum of 92 FPS. Both cards would be a good choice with this game.

Next game tested was Assassin’s Creed: Origins. This game is not very well optimized in its current state as you will see from the results. I tested this game on the Very High preset. The GTX 1070 Ti and RX Vega 56 were fairly close in performance. However, the GTX 1070 Ti comes out on top again with a 1% low of 72 FPS and a maximum of 89 FPS while the RX Vega 56 gave us a 1% low of 62 FPS and a maximum of 78 FPS.

Next, I tested Wolfenstein II: The New Colossus on the Mein leben! quality preset. Wolfenstein has always favored AMD hardware and it once again does here with the RX Vega 56 pulling a 1% low of 154 FPS and a maximum of 174 FPS against the GTX 1070 Ti’s 130 FPS 1% low and maximum of 158 FPS.

Destiny 2 was up next. This game is visually stunning but that’s about all you can say about it. I tested the game at Extreme quality settings with 4x MSAA and the GTX 1070 Ti gave us a 1% low of 116 FPS and a maximum of 128 FPS while the RX Vega 56 gave us 108 FPS at a 1% low and a maximum of 115 FPS.

Middle-Earth: Shadow of War was the next game tested and we tested this game on the ultra setting. Neither card performed exceptionally well but each did hold above 40 FPS with the GTX 1070 Ti coming in with 44 FPS at a 1% low and 88 FPS maximum while the RX Vega 56 produced 47 FPS at a 1% low and 99 FPS maximum.

I tested Player Unknown’s Battlegrounds at ultra settings. This is another game that isn’t particularly optimized and hasn’t been since release. However, it was optimized enough to allow the cards to give us decent performance. The GTX 1070 Ti again was better with a 1% low of 71 and a maximum of 86 FPS while the RX Vega 56 gave us 55 FPS at a 1% low and 68 FPS maximum.

Finally, the elder game of the 7 games tested, Prey. I tested this game on the Very High settings and the GTX 1070 Ti again came away with a performance victory. The GTX 1070 Ti gave us a 1% low of 123 FPS and a maximum of 159 FPS whereas the RX Vega 56 gave us a 1% low of 96 FPS and a maximum of 144 FPS.

Conclusion, Final Thoughts, and Recommnedations

So, there are your results. Both cards performed fairly well in the 7 games tested. Overall, the GTX 1070 Ti was a better performer and did consume less power as it only pulled 61 watts at idle and 305 at load while the RX Vega 56 pulled 69 at idle and 332 at load. With these cards, I feel in the future, you cannot go wrong with either. AMD will need to do some work on their drivers and once those are optimized, I think the performance will be close but the GTX 1070 Ti will probably still remain on top as the RX Vega 56 has more specifications in line the with GTX 1070. Currently, overall, you can look to get around 5-10% more performance out of the GTX 1070 Ti. Price to performance currently absolutely favors the GTX 1070 Ti at just around $450 whereas the RX Vega 56 cannot currently be found anywhere at a reasonable price, most likely due to the continuing mining craze. I did get a Gigabyte model about 6 weeks ago for just $400. If you can find a Vega 56 for the $400 MSRP, I think that would be a better deal for you given the Freesync capable monitors and the performance you will get with the combination of the two components. So, which one do I recommend? At current prices and performance, I would go with the GTX 1070 Ti.

Steve at Hardware Unboxed tested the GTX 1070 Ti and RX Vega 56 too... With 35 games!!!
