ZOTAC RTX 3070 Twin Edge OC Graphics Card Review

ZOTAC RTX 3070 Twin Edge OC Graphics Card Review

Final Thoughts

In a perfect world where the RTX 3070 is plentifully available, RTX 2080 Ti and RTX 2080 Super owners need not rush out and but the latest cards unless they really need but for a pure gaming perspective of someone coming off at GTX 980 Ti or GTX 1080 Ti or less, the RTX 3070 is a great upgrade thanks to its remarkable value. The ZOTAC RTX 3070 Twin Edge OC proves that performance can also fit in a tighter cooler making the card itself a very flexible option for those that currently on tighter cases but yet to make the jump to a larger one or vice versa.

Introduction

My original NVIDIA RTX 3070 Founders Edition review concluded on a note that that review was intended as a preview of things to come. The Founders Edition, instead of being a first-wave partner release has now become a collectors item only available to NVIDIA retail channel. What it does give us is performance expectation on the partner cards that are releasing today as NVIDIA is now officially launching the GeForce RTX 3070.

The original promise for this card is that it is a contender to the RTX 2080 Ti, officially lifting the performance bar to a new level for a new generation. To those who are seeing the RTX 3070 reviews for the first time, I won’t spoil you. I’ve made a dedicated summary section as we for my RTX 3070 reviews to give a side-by-side view of the performance of the cards versus the Founders Edition.

But let’s not get ahead of ourselves, let’s introduce the cards that we’re debuting with the launch of the RTX 3070. In this review, we’ll take a look at the ZOTAC RTX 3070 Twin Edge.  ZOTAC has had it rough thanks to the careless assumptions of some influencers but NVIDIA has since corrected their supposed “stability issues” and to just get straight to it, this card does not have stability issues.

More on the card itself, the sample we have is ZOTAC’s Twin Edge OC model of the RTX 3070. This card is a custom PCB design that features a 2-slot cooler but to offset the reduced length, ZOTAC has made this card extra wide with a hair over an inch protruding from the PCIe bracket which you’ll see  more of in later photos. ZOTAC’s Twin Edge cooler, with its more  subdued design is obviously aimed at compact builder. While not necessarily for ITX, compact RTX 30 series cards have been elusive and the RTX 3070 could change that.  With the performance promise of the RTX 3070, the ZOTAC Twin Edge variation could bring 4K gaming more closer to compact build. Find out how the card performs and read on!

PCIe Gen3 vs. Gen4

NOTE: This is an excerpt from my NVIDIA RTX 3080 to confirm if PCI Gen4 has a performance impact on the new RTX 30 series cards. Quick answer is no. But read on for more details:

We’ll start this off with the most frequently asked question: do I need to have PCIe Gen4 to maximize the RTX 3080? We’ll answer that here. Given that PCI Express Gen4 is only present on AMD platforms, this test will answer two questions: 1) does Gen4 have an impact and 2) do we test with Intel or AMD?

Here are our two test bench that we maintain for situations like this. I was already considering switching to AMD earlier this year but with Intel still holding on to their performance crown by a little bit, we stay for 1 more generation. Back to our test, our two systems will help us show show which system to use for this review.

For testing, we use the Final Fantasy XV benchmark. I find this benchmark more realistic than 3DMark Time Spy but speaking of 3DMark, here’s a quick summary of some tests done with 3DMark for our Gen3 vs Gen4 comparison:

This tests goes through the feature tests as well as the more intense benchmarks from the 3DMark suite. We have a 2080 Ti on the Intel system just for a quick comparison if we do get a massive jump. There is a PCI Express test in 3DMark and we can see have an improvement there, proving that gen4 is still indeed present but in actual GPU performance, Gen4 does not really impact everything as the Intel system proves the better system from pure synthetics.

Back to Final Fantasy XV, testing on the same system with Gen3 against Gen4 we get the benchmark results below:

In an AMD vs AMD setup, the difference can be accounted to standard deviation. Here’s some further charts for your reference:

The final set of charts shows us that we still get a minimal advantage on an Intel system which ultimately led me to decide to stick with our Intel system. This testing was done 3 days ago and thankfully results are favorable in my case as I would need to retest the entire lot we have.

Power Draw, Clock Speed and Temperature

We’ll switch things up and open with the power and temperature behavior of the graphics card first. We use Final Fantasy XV Benchmark to simulate a gaming workload but for those looking extreme loads, we do put our cards through Kombustor on first installation for stress testing to check for stability. For our reviews though, we use Final Fantasy XV to simulate a true gaming scenario. Power draw is captured inline via PCAT or Powenetics so no other components affects readings. Readings are taken from the average 15 min idle readings for both load and idle.

Let’s take a look at clock behavior versus temperature:

In the chart above we can follow the clock speed pattern as the card heats up during load. From the left we have the GPU clock as highlighted by the darker line and the lighter pink line is the temperature detailed on the left. Clocks climb to around 1980Mhz, that’s actually close to the boost clocks of the RTX 3080 if not pretty identical but the factory boost pushes us further than an FE 3070.

Thermal Images

The RTX 3080 showed us some of the best temps we’ve seen from a top card and that also gets passed down to the RTX 3070. With the RTX 3070, brands can get lazier with the tuning of the card and have a more silence-biased fan curve. The ZOTAC Twin Edge is a good example as it immediately stops its fan within a minute of dropping below 63*C. What’s more impressive is that its really easy to cool the RTX 3070 with heat dropping instantly even on high-stress loads, from 60*C to below 50*C in 5 seconds after the load is stopped.

Counter-Strike: Global Offensive (CSGO)

Counter-Strike: Global Offensive, popularly known as CSGO, competes for Steam’s most popular game. It has found a resurgence in its popularity and has recently peaked in 2020 in the number of players that play the game. Based on Valve’s Source Engine, the game received major asset overhauls during the years since its inception nearly 10 years ago. Still, it’s a light game and can be played on fairly lighter systems but the competitive scene for CSGO has seen average players demand high FPS from their systems thus gaining favorable standing with GPU vendors just from the demand for higher FPS alone. CSGO is a game that can easily go past 500FPS on enthusiast systems on maximum settings. We’re including CSGO as requested by our community.

DOTA 2

Note: JUNE 2020 – DOTA2 has recently implemented a transition from DirectX9 to DirectX11 and new install of the game will prompt users to switch from DX9 to DX11. With that said, we are testing DOTA2 in DX11 from now on.

In contention for the most popular game on Steam and the biggest competition in eSports: DOTA 2 is powered by the Source 2 engine. The game is fairly light on low to medium settings but maxed out, with heavy action on screen especially during clashes, can really stress most systems. This is a game where frame times matter as responsiveness is very important in high-stakes competition. We’re looking at consistently low frametimes in this  game for the best experience

Our test uses actual game replay, using the segment from game 5 of the Kiev Major 2017 Grand Finals between OG and VP. The clash during the 54:05 to 55:05 of the game is a nice example of how much a system will get punished during intense team fights in DOTA2.

You can watch the replay of the actual game used in the benchmark here in Youtube or download the replay file here for your DOTA2 client: Game 3149572447. (save it to your DOTA2 replays folder)

Rainbow Six: Siege

Nearly 4 years later and Rainbow Six: Siege has become a phenomenon after a lukewarm beginning. The massive shift in focus of the game sees it stepping into eSports territory and the excellent mix of gameplay mechanics, good design and a dedicated dev team has put R6: Siege in a position it couldn’t even picture during launch. Rainbow Six: Siege focuses heavily on tactical and creative gameplay and its vertical levels and highly destructible maps encourage players to be quick on their feet so the action is always going. Powered by Ubisoft’s own AnvilNext 2.0 engine which powers some of Ubi’s recent visual masterpieces, R6:Siege also feature excellent graphics and can get very taxing at high detail settings. The game also features an Ultra HD texture pack download for those that want higher resolution textures but will of course demand more from the system.

Grand Theft Auto V

The fifth and most successful installment to date in the highly controversial Grand Theft Auto series brings a graphical overhaul to the PC version of GTA V which many have lauded as a superior approach in porting a console game to PC. Featuring large areas and detailing, GTA V is a highly challenging application in terms of scene complexity.

Our benchmark uses a run from Palomina Highlands running through a lush area to a remote road all the way to a neighborhood in our car to simulate multiple scene changes.

Shadow of the Tomb Raider

Shadow of the Tomb Raider is the latest installment in the reboot run of the classic Tomb Raider franchise. The game follows the story set forth by the previous game which Shadow of the Tomb Raider short follows after. Technology-wise, the game uses the Foundation engine updated to meet the demand of developer Eidos Montreal to push the engine to its limits. The game supports DirectX 12 and is one of the launch titles to support RTX technology namely DLSS which launched a couple of months post-launch.

Monster Hunter World: Iceborne

Easily Capcom’s most successful game to date. Available in both consoles and PC, Monster Hunter World ranks in Steam’s top played games for the platform. The 2020 Iceborne update for PC brings the game to new PC frontier, introducing DirectX 12 support. The game features rich graphical detail settings and an Ultra HD texture pack for highend gamers. MHW’s features fast-paced action with traditional RPG farings and has captured a new market thanks to the transition from portable.

Our benchmark for this game uses an expedition track in the Wildspire Waste Southwest Camp (Area 1) and finishes in the Rathian nest at Area 12 in the caves. This run gives us runs from barren area, to watery area with lush vegetation to a cave which replicates the varied nature of exploration and monster combat in MHW.

Average FPS Summary

To provide a more focused comparison of the different RTX 3070 cards we have for review, I made this chart to show the difference of the cards on average performance. With the card performing roughly the same, a vertical chart establishes a sense of dominance over succeeding cards and I feel that’s unfair in situations like this where the difference of the cards are measured in mere decimals and standard deviation.

Conclusion

Its actually commonplace for cards to perform at the same level especially if their variations of a single model. For the ZOTAC RTX 3070 Twin Edge OC, it sits side by side-by-side with the supposed MVP of the 30-series, the TUF GAMING OC from ASUS. The cards perform the same so ultimately, that makes the decision making boil down to 3 things: aesthetics, fit and cooling.

The ZOTAC RTX 3070 Twin Edge OC features a dual-fan 100mm cooler that is not just effective in cooling but also very quiet. Ultimately, its the size and look that’s going to be the deciding factor for most users. With its shorter PCB length, it’s definitely an easy fit for most cases but its extra wide cooler makes it pop out and any case that can’t handle a 150mm cooling tower will definitely not handle this card. The reason is that the PCIe power cables makes this card protrude more so if you’re not fine tucking in cables towards to the back, you’re going to have the space to make those PCIe power cables flow. For ITX case owners, you’re going to have to be really familiar with your case on what dimensions it can fit since the length support may be fine but the width support will most likely be the problem. This will obviously be reduced by using a vertical riser. A bit of note though, I’m not trying to say this card is huge but the official photos are quite not conclusive to base size on due to the fact that its a twin-fan cooler and a shorter PCB, many could assume its a smaller card.

Talking about aesthetics, the ZOTAC RTX 3070 Twin Edge calls back to the olden GTX 1080 Ti AMP Edition design of ZOTAC: wider body with a slimmer cooler. It does get a blacker splash of paint and a more stylized backplate. There’s a light-up logo area which surprisingly does not have RGB.

Prices for the RTX 3070 start at $499 but we are still awaiting pricing details for the cards we have. The ZOTAC RTX 3070 Twin Edge OC, I expect, should be closer to the SRP range but with supply still a matter that affects pricing, I’ll save my analysis for that for now.

In a perfect world where the RTX 3070 is plentifully available, RTX 2080 Ti and RTX 2080 Super owners need not rush out and but the latest cards unless they really need but for a pure gaming perspective of someone coming off at GTX 980 Ti or GTX 1080 Ti or less, the RTX 3070 is a great upgrade thanks to its remarkable value. The ZOTAC RTX 3070 Twin Edge OC proves that performance can also fit in a tighter cooler making the card itself a very flexible option for those that currently on tighter cases but yet to make the jump to a larger one or vice versa.

ZOTAC backs the RTX 3070 TWIN EDGE OC with an extended 5-year warranty. We give it our B2G Gold Award!
