KFA2 GeForce RTX 4080 Super SG review: massive Nvidia desktop graphics card can use four fans for cooling
Nvidia rang in 2024 by launching the new Super graphics cards based on the current Ada Lovelace architecture. We had the opportunity to have a look at the new second-fastest consumer desktop GPU from Nvidia when we got our hands on the Zotac Gaming GeForce RTX 4080 Super Trinity Black Edition. The results were great, though many users had expected much more performance. In this review, we are going to focus our attention on the KFA2 GeForce RTX 4080 Super SG (Serious Gaming), which is much bulkier than its Zotac counterpart in terms of cooling design. Later in the review, we’ll discuss whether KFA2 manages to get more performance out of the graphics chip.
The new card is visually identical to the KFA2 GeForce RTX 4080 SG. The company has also given the KFA2 GeForce RTX 4080 Super SG a gigantic heat sink that takes up a little more than three slots in a computer case. Three 102 mm axial fans are permanently attached; an optional fourth fan can also be installed on the back of the graphics card. When mounted horizontally, the GPU isn’t always compatible with every motherboard. In our test rig, we vertically mounted the card and didn’t encounter any problems. All the tests below were carried out with the extra fan mounted on the rear of the GPU. The card is very long at 325 mm (12.8 in). You should definitely take this into account before purchasing the product because not every PC case offers so much space.
Aesthetically, the KFA2 GeForce RTX 4080 Super SG stands out with a ton of lit components, making it an eye-catcher. Those who love RGB are sure to get their money’s worth. But with an RRP of €1,249 (US$1,346), the manufacturer is charging significantly more than what Nvidia wants for the Founders Edition. The Zotac Gaming GeForce RTX 4080 Super Trinity Black Edition, which has braved our series of tests, sticks to Nvidia’s RRP and will set you back €1,109 (US$999). The GPU continues to use the already familiar AD103 chip. This time round, however, the chip utilises the full 10,240 CUDA cores. The new card has the same amount of VRAM as the non-Super model, but memory bandwidth has been increased due to the slightly higher clock speeds. To provide power to the 320-watt graphics card, KFA2 has gone with a revised version of the usual 12VHPWR connector – also known as the 12V-2x6.
As before, monitors can only be connected via one HDMI 2.1a and three DisplayPort 1.4a. AMD has the upper hand here with a more updated set of features, as their cards have been equipped with DisplayPort 2.1 since the 7000 series.

Clock speeds of the KFA2 GeForce RTX 4080 Super SG
For the GeForce RTX 4080 Super SG, KFA2 has retained the base clock specified by Nividia, but the boost clock has been bumped up slightly to 2,610 MHz. The card was consistently able to go much higher than that in our testing and always stayed close to the 2,800 MHz mark during our gaming tests. The KFA2 GeForce RTX 4080 Super SG too can be controlled using the Xtreme Tuner Plus tool, which allows for slightly higher base and boost clocks thanks to its 1-Click OC feature. That said, the 15 MHz more is anything but useful since the graphics card already runs much faster under load than the 2,625 MHz you get with 1-Click OC enabled.
Xtreme Tuner Plus - KFA2 tuning utility and phone app
As is usual with KFA2, the company’s own Xtreme Tuner tool lets you view essential information about the GPU and modify its clock speeds. You can also use the tool to increase the power target and provide the graphics card with up to 380 watts of power. If you don’t want to control the dazzling RGB lighting on the KFA2 GeForce RTX 4080 Super SG via the motherboard, you can select one of the many predefined effects in the software. All the settings in Xtreme Tuner are also easily configurable using a smartphone. The setup process is quick and requires you to scan a QR code. But you need to ensure that both the PC and smartphone are connected to the same network.
Synthetic benchmarks
Looking at the results of the synthetic benchmarks, we only saw a slight increase in performance over the KFA2 GeForce RTX 4080 SG. In addition, we noticed the KFA2 GeForce RTX 4080 Super SG isn’t able to outperform the Zotac Gaming GeForce RTX 4080 Super Trinity Black Edition. Even though our review unit has a much bulkier cooler, we ultimately couldn’t get more performance out of it. The Nvidia GeForce RTX 4080 Super also couldn’t close the gap on the GeForce RTX 4090. Nividia’s top-end model continues to consistently deliver 20 to 30% more performance.
Against the competition from Team Red, the GeForce RTX 4080 Super can keep pace with AMD’s flagship graphics card, the Radeon RX 7900 XTX. In LuxMark and ComputeMark, our Nvidia card even managed to pull far ahead of the Radeon GPU. However, the results from PugetBench for Photoshop paint an entirely different picture.

Professional applications
Consumer graphics cards are suitable for professional use only to a limited extent. The reason for this is a lack of hardware support, which is primarily only reserved for professional graphics cards. Nonetheless, it’s still possible to use consumer GPUs for professional applications, albeit with performance loss. The new Super model similarly didn't surpass its predecessor by an appreciable margin here. You will get more performance from the Nvidia GeForce RTX 4090 or AMD RX 7900 series cards. Making a comparison with the Nvidia RTX 6000 Ada Generation (included in the table below) demonstrates what kind of performance can be achieved with a specialised workstation graphics card. AMD likewise offers workstation GPUs with their Radeon Pro models.

Gaming performance
As in the synthetic benchmarks, the KFA2 GeForce RTX 4080 Super SG also didn't outperform the Zotac Gaming GeForce RTX 4080 Super Trinity Black Edition in our gaming tests. The review unit often ended up behind the Zotac card, though their performance is more or less comparable. What’s disappointing is the performance gain over the KFA2 GeForce RTX 4080 SG, which is just in the single-digit percentage range. This means we are a long way from getting any meaningful differences. But the lower price tag is an argument for the new Super model. If you can find an “old” Nvidia GeForce RTX 4080 for a good price at a clearance sale, it really isn’t necessary to go for the new Super card.
All the games used in our testing ran smoothly at 2160p and max settings. But this was already the case with the predecessor. The GeForce RTX 4080 Super is still fitted with only 16 GB of VRAM, which puts it at a disadvantage compared with AMD cards. Both the Radeon RX 7900 XT and the RX 7900 XTX offer significantly more video memory at 20 GB and 24 GB respectively. Right now, it’s worth taking a look at AMD because the company recently adjusted their GPU prices downwards. An AMD Radeon RX 7900 XTX may thus be a sensible option, considering various models are selling for as low as approx. €950 (US$1,025) at retailers.
Ray tracing, DLSS and Frame Generation
For those who don’t want to forgo features like ray tracing, Nvidia graphics cards currently provide better performance than their AMD counterparts. The KFA2 GeForce RTX 4080 Super SG boasts over 80 RT cores and thus offers slightly more performance than its non-Super predecessor. There are also 320 Tensor cores on board, which are required for DLSS and can significantly improve frame rates. If you want to use real-time ray tracing at 2160p resolution, it is essential to do so in combination with DLSS. Frame Generation is another way offered by Nvidia to increase frame rates. AMD’s FidelityFX Super Resolution 3 (FSR 3) is an alternative to DLSS and can even be used by Nvidia GPU. By contrast, DLSS is only available on Nvidia’s 20 series graphics cards and above.

Emissions - Massive cooler with four fans
Noise emissions
KFA2 has given the GeForce RTX 4080 Super SG a colossal heat sink with three 120 mm fans. An optional fan of the same size can be attached to the back of the card. Depending on the mounting method and hardware used, you may encounter compatibility issues that prevent the use of the optional fan. During our testing, we mounted the GPU vertically and didn’t experience any problems using the extra fan on the rear. One positive thing to highlight is the fan-stop mode, which allows the graphics card to run silently in 2D applications.
To determine how loud the graphics card runs, we installed the KFA2 GeForce RTX 4080 Super SG in our open test rig for noise measurement. As mentioned earlier, the fans don’t run at idle, enabling silent operation. The fans spin slowly at low load; in our testing, the review unit was barely audible at 26.7 dB(A). But the four fans revved up a decent amount during the stress test, and we measured a peak noise level of 44.3 dB(A). This means the graphics card is audible even when inside a closed case. Thanks to the fan frequencies, the noise level sounds somewhat quieter to the ears. We didn’t notice any annoying whistling or coil whine coming from our review unit.

Temperatures and power usage
The KFA2 GeForce RTX 4080 Super SG was able to sustain peak performance during our stress test. However, we saw a max GPU hotspot temperature of 82°C (179.6°F), which caught our attention immediately given how large the cooler is. But the competing product from Zotac got even warmer at 85°C (185°F) in our testing. All in all, our review unit ran slightly cooler than the Zotac model on average. The graphics chip itself reached just a little higher than 70°C (158°F), whilst the VRAM only reached 64°C (147.2°F) according to HWiNFO.
Up next, we’re going to turn our attention to the test system’s power consumption: at the mains socket, we measured an average power draw of 441 watts and 489 watts during the stress test and gaming test respectively. We also evaluated the GPU’s power consumption separately using the ElmorLabs PMD (power measurement device): the KFA2 GeForce RTX 4080 Super SG exhibited brief power spikes of up to 431 watts. In light of this, it is understandable why the manufacturer recommends using at least a 750-watt power supply made to the latest ATX 3.0 specifications.

Verdict - Massive RTX 4080 Super with tons of RGB
With the KFA2 GeForce RTX 4080 Super SG, the manufacturer has made product update simple for themselves. The graphics card is visually identical to its predecessor. There are only minor changes to the specs that go hand in hand with utilising the entire die of the AD103 graphics chip. Whilst the KFA2 GeForce RTX 4080 Super SG got a slight performance boost, it doesn’t translate to a subjectively noticeable improvement. But things look different when put in relation to the price, because the newer model launched at a much lower RRP than the non-Super model. As a result, it’s possible to overlook at the relatively small performance jump.
The KFA2 GeForce RTX 4080 Super SG has impeccable build quality. Of course, the card’s size carries a few issues with it. Measuring slightly longer than 35 cm (13.8 inches), the graphics card can’t fit in every PC case. The already familiar design stands out with stylish RGB lighting that you can also conveniently control using a smartphone app.
The KFA2 GeForce RTX 4080 Super SG is a snappy graphics card for 4K gaming. Together with its snazzy RGB lighting, the card is also a treat for the eyes.
The review sample from KFA2 impressed us throughout our review with its great and consistent performance. For the most part, the graphics card falls just behind the Nividia RTX 4090 and is thus faster than AMD’s current flagship, the Radeon RX 7900 XTX. Enabling ray tracing further widens the gap between Team Green and Team Red. Nvidia is able to pull ahead considerably in this area; whoever doesn’t want to miss out on ray tracing should go for an Nvidia graphics card. With an RRP of €1,249 (US$1,346), the KFA2 GeForce RTX 4080 Super SG isn’t able to keep up with an AMD Radeon RX 7900 XTX as far as price goes. The Radeon GPU can already be had for about €950 (US$1,024). It is also equipped with 24 GB of VRAM, whereas Nvidia still insists on sticking to 16 GB.
