Kfa2 rtx 2070 ex review in Spanish (full analysis)

KFA2 is back with us and has brought us a good candy, KFA2 GeForce RTX 2070 EX (1-Click OC), which is surely the best RTX 2070 in quality / price, reaching just 500 euros. A real beast with an effective custom 100mm RGB dual fan heatsink with a 1-Click OC system. A RTX range that we know perfectly for the most demanding.

Of course we thank KFA2 for their trust in us and for giving us this GPU for analysis.

KFA2 GeForce RTX 2070 EX technical features

Unboxing and design

The presentation of KFA2 GeForce RTX 2070 EX does not keep too many secrets and consists of a box as always of considerable dimensions, and made of thick cardboard to protect each unit to the maximum. In turn, it is stored in a flexible cardboard lining, which is what we see from the outside. On the main face we see a photo in true gaming style together with the RTX 2070 model and its 1-Click OC function.

If we turn the box around, we will see the technical information regarding the card, speciations and of course the characteristics of the heatsink with double fan and RGB lighting.

After this, it's time to unpack the graphics card so we remove the outer packaging and open the main box. We find it tucked inside an antistatic plastic bag and fully attached in a protective mold. Inside we will also find the user and warranty documentation along with the corresponding drivers. We always recommend installing the latest version of these, so for this we will access the Nvidia page and also the KFA2 page that has a direct link to these.

The KFA2 GeForce RTX 2070 EX is a graphics card that in terms of external appearance is not the most striking, but soon you will see that this does not mean that we have assured performance. We then have a plastic housing that protects the entire thick dissipation block, with an infinity of angular faces with a futuristic style, although entirely painted in black.

Also visible are its two transparent fans with integrated RGB lighting. The overall dimensions are 295 mm long, 143 mm wide and 51 mm thick, so it will occupy a total of 2.5 expansion slots in our chassis. Keep this in mind because it is not a small card.

In terms of performance, KFA2 has chosen to keep the GPU frequency identical to the reference model, that is, 1410 MHz at normal speed and 1620 MHz in turbo mode. Although it has implemented a 1-click OC function that through the brand's software we can raise the frequency to 1665 MHz, which is not crazy, especially if we take into account the OCs of other manufacturers.

And of course, if we have to talk more carefully about a custom GPU such as this KFA2 GeForce RTX 2070 EX, it is the cooling system. In this case we find at a glance a system provided with a double aluminum block together with two fans of 100 mm in diameter each with alternate rotation.

The system has Silent Extreme technology, which is in charge of managing the fans intelligently so that they only start when necessary. The maximum air flow they provide is 70.1 CFM (120 m ³ / h), along with a pressure of 4.31 mmAq (millimeters of water), being 200% higher than standard fans. Due to these features, they are capable of dissipating a TDP of up to 300W.

If we turn it around, what we find is a large blackplate made of aluminum and decorated in black with white elements. Almost the entire surface has been stamped to allow the entry and exit of air by natural convection so that heat does not accumulate in this back plate. Of course, it will also function to prevent deformation of the PCB due to its own weight.

The KFA2 GeForce RTX 2070 EX communication interface consists of the traditional 3rd generation PCI-Express x16 slot. In addition, we must remember the RTX 2070 does not have multiGPU SLI or NVLink technology, since it is only available on the Nvidia GeForce RTX 2080.

We will also take the opportunity to see that the main power system has a 6-pin connector next to an 8-pin second. Let's not forget that this high performance card has a TDP of 185W and we recommend installing it with a power supply of at least 650W.

Continuing with the connections of the KFA2 GeForce RTX 2070 EX, now we are going to take a closer look at what its large rear panel offers us. In total, it installs two DisplayPort 1.4a ports and one HDMI 2.0b port. The presence of the VirtualLink connector could not be missing either, which is basically a USB Type-C that works the same as our PC. So we can even connect Flash units or peripherals in addition to VR glasses.

We already know that the new RTX decoding engine supports HDCP 2.2 and DSC lossless. We will also be able to reach 8K @ 30 Hz and 8K @ 60 Hz resolutions with DSC activated.

Heatsink, PCB and features

Surely many of you already know them, but for those who do not, we will go on to give a good review of the technical specifications of the KFA2 GeForce RTX 2070 EX. We have taken the liberty of removing the heatsink to take a closer look at what is inside. For this, it is only necessary to remove the screws that hold it to the blackplate and also to the housing.

The heatsink consists of a double aluminum block with a fairly dense and bulky finning. The contact area with the GPU and components is built on a copper plate from which four heatpipes come out for each dissipation block. In addition, in the main block, which makes direct contact with the GPU, increases the transfer with two of the heatpipes turned on itself towards the sides.

The thermal pads for the VRM area and the eight GDDR6 memory modules could not be missing either. Before seeing the temperature results, we already know that this system will work like a charm. Especially in a GPU with as little lap as this is, the temperatures will be even better.

KFA2 GeForce RTX 2070 EX features impressive 6 + 2 phase VRM with high quality MOSFET and durability. These are protected with inductors against surges caused by demanding overclocking, for example.

Once again, we insist that this 185W TDP and forceful heatsink will surely allow us to do a good overclocking, in addition to the 1-click OC function available in the Xtreme Tuner software.

The benefits of this high-end graphics processor you should already know, although it is our obligation to give them in as much detail as possible. It is a GPU with a Turing architecture chip with the specification name TU106 12nm FinFET. It will be able to provide in this model a normal frequency of 1410 MHz and 1665 MHz in OC mode when we activate it from software. This GPU is made up of 2304 CUDA Cores, 288 Tensor Cores and 36 RT Cores that will be in charge of rendering the image using DLSS (Deep Learning Super Sampling) with the Tensor, and to perform Ray Tracing in real time using the RT cores, giving a power of 6 Giga Rays per second.

For graphics memory, Nvidia has mounted a single configuration on its 2070s, consisting of 8GB of GDDR6 memory. It is capable of working at a speed of no less than 14 Gbps under a 256-bit bus width and a bandwidth speed of 448 GB / s, compared to the 192 bits of the RTX 2060 for example. The positive thing about this RTX range is that all of them have GDDR6 memories.

We will have a capacity to connect four monitors, HDCP 2.2 compatibility and we will be able to achieve a digital resolution of 8K (7680 x 4320 pixels), which with DSC activated, we will be able to reach a refresh rate of 60 Hz. It is a great detail that the brand I have not removed the VirtualLink port to place another video connector, since this can be quite useful for VR.

Test bench and performance tests

For benchmarks we will use the following titles:

• 3DMark Fire Strike normal3DMark Fire Strike version 4KTime SpyVRMARK

All tests have been passed with the filters to the maximum unless we indicate otherwise. In order to have adequate performance, we have carried out three types of tests: the first is the most common at Full HD 1920 x 1080, the second resolution is making the leap for 2K or 1440P (2560 x 1440P) gamers and the most enthusiastic with 4K (3840 x 2160). The operating system we have used has been Windows 10 Pro 64 bit and the latest drivers available from the Nvidia website.

What are we looking for in the tests?

First, the best possible image quality. The most important value for us is the average FPS (Frames per second), the higher the number of FPS the more fluid the game will go. To differentiate the quality a bit, we leave you a table to assess the quality in FPS, but we will also have the minimum Fps in the tests that were thus possible:

FRAMES BY SECONDS
Frames for Seconds. (FPS)	Gameplay
Less than 30 FPS	Limited
30 ~ 40 FPS	Playable
40 ~ 60 FPS	Good
Greater than 60 FPS	Fairly Good or Excellent

Game Testing

We have decided to make the leap to checking various games manually. The reason? Very simple, we want to give a much more realistic vision and cover tests with current games. We've revamped the old 2016 Tomb Raider for this new Shadow of the Tomb Raider.

Overclocking

Note: Each graphics card can go up at different frequencies. Does it depend a little on how lucky you are?

At the overclocking level we have been able to give it a little boost in the memories (+1963 MHz) and in the core up to 1510 MHz. As standard it runs from 1850 MHz, with this improvement we have reached ~ 2000 MHz. At benchmark level We see a great improvement and in games we think that overclocking is very worthwhile, since it does not harm the GPU. The game used is DEUS EX, let's see the results obtained:

Deus Ex: Mankind Divided	Stock	@ Overclock
1920 x 1080 (Full HD)	111 FPS	120 FPS
2560 x 1440 (WQHD)	78 FPS	84 FPS
3840 x 2160 (4K)	42 FPS	45 FPS

Temperature and consumption

We have obtained 35 ºC at rest because the fans are deactivated until they reach 60 degrees . Once the fans are started at full load, we obtain an average of 61 ºC. Great temperatures.

Consumption is for the entire team *

The consumption of the equipment is 48 W which when we upload the work to the GPU amounts to 250 W. Although if we stress the processor we get approximately 320 W. These stockings are totally normal and is due to the good work that Nvidia is doing in these last generations.

Final words and conclusion about KFA2 RTX 2070 EX (1-click OC)

The KFA2 RTX 2070 EX is an excellent choice for the user looking for something good, beautiful and cheap in Nvidia's RTX 2070 range (considering the starting price they have). It has 6 + 2 power supply phases, one of the best heatsinks we've tested so far (both for robustness and performance), very quiet overall and a backplate that helps improve rigidity in your installation and better dissipate heat. Very good work!

As many of you know, the KFA2 RTX 2070 are the perfect ally for Full HD and 2K resolutions. Although 4K defends itself, it is not the most interesting option. Her older sisters are better options for enthusiastic resolution.

We recommend reading our guide on Best graphics cards

In our test bench it has been great. Giving the expected FPS in our usual games and passing all our benchmarks without any problem. At the overclock level we can scratch about 4 to 8 FPS.

Currently we can buy it in the main online stores for a price of 509.90 euros. Still having one of the lowest prices in the RTX 2070 series, we think it is one of the best models. Going over manufacturers better positioned at the marketing level in Spain than KFA2. For us, it is one of the 100% recommended purchases. What do you think of this brand?
