KFA2 GeForce RTX 4070 EX Gamer desktop graphics card review: A quiet, cool and frugal GPU for WQHD gaming
Bit by bit, the new mid-range Ada Lovelace architecture graphics cards are being released by Nvidia. After extensively testing the performance of the KFA2 GeForce RTX 4070 Ti SG, now it is time to take a look at the model without the Ti abbreviation. To be more precise, we are looking at the KFA2 GeForce RTX 4070 EX Gamer, which is slightly smaller but still delivers impressive performance. There are a good $300 between the two, but none of the GeForce RTX 4070 graphics cards are exactly the cheapest when it comes down to it. Even so, the KFA2 GeForce RTX 4070 EX Gamer is a model which will set you back around $650. This seems cheap compared to the GeForce RTX 4080, but many set their limits at around $500 for a mid-range graphics cards. In comparison: The Nvidia GeForce RTX 3070 FE had an MRSP of around $550 at its release in 2020. Unfortunately, a combination of global economic issues - as well as the mining boom - let to a hike in prices. They only gradually declined back to somewhat normal levels - but even so, inflation still proves to be a big issue. We just have to hope that this trend doesn't continue for much longer and that prices will slowly plateau at a level which most PC gamers will be happy with. But now, back to the graphics card. In direct comparison, the KFA2 is still well-equipped and gained some points due to its price and great features.
Visually, the KFA2 GeForce RTX 4070 EX Gamer appears almost small compared to the GeForce RTX 4080 or the Geforce RTX 4090. But the KFA2 GeForce RTX 4070 Ti SG was also much bigger due to its extremely large cooling unit. Nevertheless, the KFA2 GeForce RTX 4070 EX Gamer has a large cooler with three fans, which also feature some snazzy RGB lights. At just over 2 slots, the graphics card is not quite as thick as the more powerful models such as the 4070 Ti. KFA2 can take this step, as the GeForce RTX 4070 EX Gamer now only has a power consumption of 215 watts. As a result, its power supply remains to be a tried-and-true 6+2 pin PCIe connection. Externally, the KFA2 GeForce RTX 4070 EX Gamer has 1 HDMI 2.1a and 3 DisplayPort 1.4a connections.

Details about the KFA2 GeForce RTX 4070 EX Gamer
In the GeForce RTX 4070 EX Gamer, KFA2 deviate slightly compared to the technical specs of Nvidia's Founders Edition. More specifically, its power consumption is specified at 215 watts, which is 15 watts higher than the reference card. Along with that, it also has a higher boost clock, although the GPU's base clock and also the VRAM's speed remain untouched. The maximum power limit can't be increased any further.
Synthetic benchmarks
Now, we will take a look at the synthetic benchmarks, which will give us some insight into the GPU's performance and how it compared to its competitors. Here, the KFA2 GeForce RTX 4070 EX Gamer ranked directly behind the KFA2 GeForce RTX 3080 SG. At higher resolutions, our test device began to stumble more often, which you can see clearly looking at the Unigine Superposition results. It ranked 20 per cent behind the Ti model of the GeForce RTX 4070. The KFA2 GeForce RTX 4070 EX Gamer's performance compared to a KFA2 GeForce RTX 3080 SG is still considerable. Both performed similarly well, but with regard to power consumption, the Ada Lovelace model lay clearly ahead. The results of 215 watts vs. 320 watts speak for themselves and show that Nvidia have quite the lead when it comes to efficiency.
Taking a look at compute performance, there wasn't a clear winner. At times, Nvidia and AMD took the lead due to their software, which fits better with their corresponding architecture. So if you are looking to use your graphics card for the occasional video rendering, then you might want to consider which model is most suited to this in advance. Streamers should be happy with Nvidia's RTX 40 series because they support AV1 encoding. If Twitch switch to using the new codec at any point in the near future, then you will be best equipped with an Nvidia graphics card on Ada Lovelace architecture.

Gaming benchmarks
During our gaming tests, we utilize a wide range of games - from older ones right up until the most recent games of 2023. We were able to come to the conclusion that the KFA2 GeForce RTX 4070 EX Gamer mastered all the games we tested at 1,440p and with maximum details - without any issues and at playable frame rates. Some games can even be enjoyed at 2,160p, but then you will have to settle for frame rates of under 50 at times. At this point, we would like to mention that the KFA2 GeForce RTX 4070 EX Gamer is in the race for its 1,440p gaming. If you are looking for a 2,160p gaming experience with no compromises, then you should be looking at a more powerful graphics card such as an Nvidia GeForce RTX 4080 or an Nvidia GeForce RTX 4090.
Compared to the KFA2 GeForce RTX 3070 Ti SG, our test sample did 20 per cent better. However, the KFA2 GeForce RTX 4070 EX Gamer simply cannot keep up with AMD. But, it doesn't need to - as AMD's Radeon RX 7900 XT and Radeon RX 7900 XTX have a completely different target audience. We will likely have to wait a bit longer for the red camp's mid-range offshoots of the RDNA3-based graphics cards.
With activated light effects such as ray tracing, we could see a similar thing when looking at Nvidia's graphics cards. Compared to AMD, the KFA2 GeForce RTX 4070 EX Gamer came very close to the AMD Radeon RX 7900 XT. But without the help of KI, we only observed playable frame rates at 1,080p with activated ray tracing. Using DLSS 3.0 - which can also be found on the small Ada Lovelace GPU - declines in performance with activated ray tracing can mostly be made up for. DLSS can also be used without activated ray tracing, which leads to most modern games being able to be played smoothly and without any notable loss of detail at higher resolutions. What AMD will have to offer with their announced FSR 3, we will just have to wait and see. Right now it has to be noted that Nvidia still continue to offer the best total concept and in terms of ray tracing, they still lay miles ahead of AMD.

The KFA2 GeForce RTX 4070 EX Gamer's emissions
Noise emissions
To take our noise emission measurements, we used our test sample while it was open. During our test, all other noise sources - such as the CPU fan and power adapter fan - were deactivated. The test showed us a passively working graphics cards which also worked very quietly at moderate load - we measured noise levels of 31.8 dB(A). In our stress test, we measured the highest rate of 41.1 dB(A). At this point, the fans were rotating at around 1,600 rotations per minute. While gaming, we measured noise levels of 37.9 dB(A), which - subjectively seen - is a relatively good result. In our test sample, we sometimes noticed some slight coil whining. However, at 31.5 dB(A), you shouldn't be able to hear it when the system is closed.

Temperatures and power consumption
The KFA2 GeForce RTX 4070 EX Gamer is equipped with a large cooler, which when installed takes up just over two slots. The built-in fans measure 92 and 102 millimetres in diameter with the bigger fan being positioned in the middle. Not only the design looks good - the same can be said for its performance. The graphics card's 215 watts are effectively dissipated. At no point were any thermal limits reached which would lead to a dip in performance. In our stress test, we noted a peak of 71.3 °C, although the GPU only reached 58,.4 °C on average. At 2,580 MHz, the GPU clocks at a rate above its base clock.
The KFA2 GeForce RTX 4070 EX Gamer surprised with good power consumption results. In comparison, no other combination was more efficient than the one we tested. Its results of 360 watts during gaming and 330 watts during the stress test are great and are much better than those of the KFA2 GeForce RTX 3070 TI SG.
The manufacturer's recommendation for a power adapter is noted as being 600 watts. You need to be careful as to not neglect the system's other components. To be on the safe side, we agree with this recommendation - even if we only measured a maximum of 360 watts in our system when gaming.

Verdict - Good performance and very efficient
We put the KFA2 GeForce RTX 4070 EX Gamer, a mid-range graphics card based on Ada Lovelace architecture, through our extensive tests. Generally, the GPU delivered solid performance in all areas of use. However, you can't ignore the graphics card's size. Compared to the Nvidia GeForce RTX 4070 Founders Edition, the KFA2 GeForce RTX 4070 EX Gamer has a considerably larger cooling element and a power limit of up to 215 watts. This is enough to at least compete with an Nvidia GeForce RTX 3080 - the performance advantage of the Nvidia GeForce RTX 3070 is more noticeable. With regard to efficiency, the graphics card performed very well - 215 watts give you the same performance as a GeForce RTX 3080, which uses 320 watts and puts much bigger pressure on the power adapter as well as your wallet.
The KFA2 GeForce RTX 4070 EX Gamer is very frugal and still manages to deliver exceptional performance for 1,440p gaming. With 12 GB VRAM, you are currently still well-equipped.
The device's build is immaculate and the RGB lights provide a great user experience. If you don't care for light shows, you can of course deactivate this feature. You could argue that the manufacturer has taken a step backwards in terms of power supply - the model no longer features a 12VHPWR connection. Instead, it has an older generation 6 + 2 pin power connection. This is beneficial for anyone who doesn't yet have an ATX 3.0 power adapter and can't be bothered with ugly adapter solutions.
Prices and availability
You currently cannot yet purchase the KFA2 GeForce RTX 4070 EX Gamer on online retailers in the USA, but you can find many other models on Amazon, such as the GeForce RTX 4070 Ti.
The KFA2 GeForce RTX 4070 EX Gamer will retail for around $650. You can read more about the GPU on KFA2's website.
