KFA2 GeForce RTX 4090 SG review: Uncompromised 4K gaming with the new Nvidia flagship

Peerless speed! Nvidia's current GeForce RTX 4090 graphics card offers a performance we have not seen before, surpassing the former top model significantly. In this review, we examine the KFA2 GeForce RTX 4090 SG and also compare the performances of the various RTX-4090 models with each other.

Nvidia's current top model delivers an impressive performance. We already saw this in form of the Palit GeForce RTX 4090 GameRock OC and the Nvidia GeForce RTX 4090 Founders Edition. With the version from KFA2, we take a look at an additional model from the current high-end class. 

For this test, we use the KFA2 GeForce RTX 4090 SG. The manufacturer considers the graphics card at the same level with the Asus GeForce RTX 4090 Strix and the MSI GeForce RTX 4090 Suprim X, both of which are the top models from the respective manufacturer. Unfortunately, we are unable to offer you a direct comparison with those competitors and the KFA2 GeForce RTX 4090 SG, since we have not been able to get our hands on either of those models yet. The KFA2 model is very large, which is really also the case for all models of the RTX 4090. The Quad Slot design takes up a lot of space in the case and promises a quiet graphics card under load. For the fans, the manufacturer uses three large axial fans with a 102-mm (~4 in) diameter. They were redesigned and offer up to 25% more volume throughput. The power consumption is 450 watts, following also the  reference model from Nvidia. As in all models of the GeForce RTX 4090 graphics card, the new 12VHPWR connection is used for the power supply. The corresponding adapter to 4x 6 + 2 Pin PCIe is included.

Externally, the KFA2 GeForce RTX 4090 SG offers 1x HDMI 2.1a and 3x DisplayPort 1.4a connections.

Our Test System Based on AMD Ryzen 9 7950X

A current AMD platform based on the Gigabyte X670E Aorus Master serves as our test system. The CPU (AMD Ryzen 9 7950X) offers a good performance, and we use an AiO solution from Alphacool (Alphacool Eisbear Aurora 360 mm) for cooling. The 32-GB working memory comes from G.Skill and is run with the corresponding EXPO profile. For the monitor, we use the Gigabyte M32U.

In terms of the clock speeds, KFA2 sticks exactly to the manufacturer guidelines in the GeForce RTX 4090 SG. With this, up to 2,580 MHz for the Boost are specified for the GPU on paper. However, this is only a recommendation, and in practice we observe significantly higher clock speeds throughout in our games tests. At 2,730 to 2,760 MHz, the AD102 of the KFA2 GeForce RTX 4090 SG runs mostly above the specified Boost rate. With the Xtreme Tuner, the manufacturer offers a small tool to read all the important values of graphics card. For example, it allows you to control the illumination or adjust the fan curve. We did not change any of the predefined values for the test. However, the 1 Click OC feature, which is often used in KFA2 models, is more of an illusion than a real benefit. An only 15 MHz increase in the GPU clock speed doesn't make any difference in practice. We would wish for this feature to bring a more significant improvement.

Synthetic Benchmarks

In the synthetic tests, we observe an almost identical performance compared to the Palit GeForce RTX 4090 GameRock OC, but our test unit still places slightly behind the Palit graphics card. Subjectively, both models offer the same speed. The performance increase in direct comparison to the Nvidia GeForce RTX 3090 is very large (with 90 compared to 57 points). At the same time, the Nvidia Titan RTX also does fairly well. Following the Quadro series, the graphics card is able to achieve a significantly better performance here in the render tests due to the driver optimizations.

Compared to AMD, the KFA2 GeForce RTX 4090 SG is also easily ahead. The comparison with the Sapphire AMD Radeon RX 6950 XT shows a performance advantage of 53% on average. However, with the AMD Radeon RX 7900 XTX, the successor is already in sight. By mid-December, it should be here, and the next battle between the red and the green camp can begin.

Gaming Benchmarks

The KFA2 GeForce RTX 4090 SG is able to convert the high performance in the synthetic benchmarks also into a very high gaming performance. When it isn't limited by the CPU, a performance increase of more than 80% compared to the Nvidia GeForce RTX 3090 is possible. In the past, we have only rarely seen such a high performance increase between two GPU architectures. KFA2 and Palit are again at eye level, and we are unable to see any significant differences between the two models.

The special RTX 4000 features such as DLSS 3.0 including Frame Generation (FG) ensure an additional boost in many games. As an example, we can mention Cyberpunk 2077. In native 4K resolution and the Raytracing Ultra preset, even the KFA2 GeForce RTX 4090 SG only reaches 44 FPS on average. But with DLSS activated, more than 100 FPS are no problem anymore. With this, Nvidia offers a great feature, which could really make the difference in the purchase decision in the near future. On the other hand, with FSR, AMD has a similar feature in the works. So in the end, it depends on the gaming manufacturers and whether they integrate these features in their games. You can find a list of the games that already support DLSS 3.0 or plan to do so in the future here.

The power consumption of the KFA2 GeForce RTX 4090 SG is not an exception compared to other GeForce RTX-4090 models. At 450 watts, the standard power limit is just as high as that of other RTX-4090 models. However, there are some deviations among the various models in the optional power target. With an additional 13%, you can increase the power limit of the KFA2 GeForce RTX 4090 SG to about 510 watts. Nvidia's Founders Edition even allows for up to 600 watts, and the Palit GeForce RTX 4090 GameRock OC only 500 watts. But in practice this doesn't play a major role, since only in the rarest cases the power limit of 450 watts is even reached. The consumption in the FurMark stress test is slightly higher than 370 watts. At that time, the GPU temperature remains a cool 65 °C (145 °F), and the fan speed is only 1,300 revs per minute. At 39 dB(A), the graphics card is quietly audible.

The KFA2 GeForce RTX 4090 SG uses a massive heat sink with three large 102-mm (~4 in) axial fans. Optionally, you can also install an additional 102-mm fan on the back. However, you have to make sure about the compatibility with the mainboard that is used. In our case, we were unable to install the additional fan, since the RAM banks of the Gigabyte X670E Aorus Master prevented this.

If we compare this with the power consumption of the whole test system, it is about 546 watts while gaming. This is only slightly more than compared to the Nvidia GeForce RTX 3090 Founders Edition. At the same time, we still measure a significant performance increase, so the GeForce RTX 4090 takes a huge step ahead in terms of the performance per watt. We also measure some consumption peaks of up to 700 watts for our test system. KFA2 specifies a power supply capacity of at least 850 watts for the GeForce RTX 4090 SG. Some other manufacturers, on the other hand, specify at least 1,000 watts, which is a bit too high, in our opinion.

In terms of the 12VHPWR connection, we want to point out here that you have to make sure that the plug sits completely and correctly in the connector. But there were no problems in this regard with any of the RTX-4090 models that we tested so far.

Those who are looking for the fastest graphics card currently won't get around a Nvidia GeForce RTX 4090. Only rarely can we find such a large performance jump between two successive generations. Nvidia has also increased the power consumption by 100 watts, which corresponds to that of the top model until now, the Nvidia GeForce RTX 3090 Ti. However, we only rarely encountered the maximum of 450 watts for the GPU, which also means that the GeForce RTX 4090 is currently not used to the fullest in all the games. The KFA2 GeForce RTX 4090 SG is no exception here, offering the same performance as our much-used test unit, the Palit GeForce RTX 4090 GameRock OC. Due to the very large heat sink and three large fans, the temperatures always remain within the green range. Gimmicks like RGB are also included and can be controlled easily using the inhouse software. The same goes for the fans that even remain turned off in 2D operation or under low loads.

The KFA2 GeForce RTX 4090 SG is a very good graphics card that impresses with a very high gaming performance throughout. An extremely large heat sink, up to four fans, and a lot of RGB illumination attract attention with the KFA2 model.

Some coil whine is a bit too present and more audible in subjective comparison than with the competitor from Palit. However, we still wouldn't call this annoying. While you can have different opinions on the 12VHPWR connection used, we did not encounter any problems so far. The positioning of the 12VHPWR connection is not optimal, since the large adapter, which shouldn't be bent directly next to the graphics card, creates some space problems in many cases.

The RTX 4090 currently doesn't have any direct competitors, which now only leaves the different manufacturers to compete with each other. According to their own announcements, KFA2 competes with the Strix model from Asus und the Suprim X model from MSI. If you look at the direct performance data, there are no significant advantages here in terms of performance technology. This means that currently, the manufacturers can only draw some attention with the extent of the performance, the visuals, and the price. AMD is currently unable to keep up with its top model, and we have to wait patiently until the AMD Radeon RX 7900 XTX becomes available.

Price and Availability

There are currently no problems with the availability of the graphics cards (in Germany), even if the prices are much higher compared to the MSRP specified by Nvidia (1,949 Euros, ~$2018). For example, the KFA2 GeForce RTX 4090 SG is currently available for 2,749 Euros from Amazon (in Germany). It appears to be harder to find the US: while it is not listed at Amazon, and Ebay shows it as "sold out," one online discounter shows it on sale for $1400. It appears to be sold in some markets under the "Galax" brand.
