The AMD Radeon RX 6600 has finally been launched on the market and as always is accompanied by different variations different from the graphics card manufacturers, which we call custom or custom models. These models take the basic specifications given by the GPU designer to create their own PCBs, power and cooling systems with a single element in common, the GPU and VRAM that are provided to them.
These are the general specifications of the AMD RX 6600
The central GPU in the AMD RX 6600 graphics card is the same as the one we can see in the RX 6600 XT, but with a variation in the number of Compute Units or Shader Units that are active on the chip, 28 instead of 32, so the performance is somewhat lower because of it. The rest of the elements are maintained as is the case of the 128-bit bus that is linked to GDDR6 of 16 Gbps that allows you to obtain 8 GB in the form of 4 chips of 2 GB each, support for all the technologies of the RDNA 2 architecture on PC and 32 MB of Infinity Cache, the same figure as the XT model.
It is a GPU designed to enjoy the latest generation games at Full HD resolution at high frame rates in medium-high quality levels, depending on each title, so it is an excellent replacement for an old graphics card of the same range such as the old RX 480 or RX 580 from AMD itself or the GTX 1060 from NVIDIA in its two versions of 3 and 6 GB. However if you have an RTX 2060 the jump is not so great and it is not worth the change.
Since the RX 6600 is a trimmed version of the XT model, most manufacturers of custom models have not had to put themselves at the design table to launch totally different custom models than those launched a couple of months ago with the launch of the previous model. The reason is that they can mount a graphics card with the same components in a short time and that it works for them without problems.
MSI RX 6600 MECH 2X
The first custom model of the RX 6600 that has caught our attention is that of MSI, under the name of the MSI RX 6600 MECH 2X, which reminds us that it is a version of the same graphics card that came out among the custom models of the XT version of the GPU and therefore shares the same elements outside of the GPU specifications. First of all we have a pair of TORX FAN 3.0 fans, MSI’s own design that in its third generation achieves an air pressure 15% higher than the previous one and up to 50% higher than a normal fan.
The second of the technologies is the one baptized as Zero Frozr, which is none other than the ability of the graphics card to turn off its fans when its temperature is low enough. Already to finish the manufacturer promises a lot of Thermal Pads quality around your RX 6600 MECH 2X, something that should be taken for granted, but that with the decline in quality in manufacturing due to the shortage of components is important for the consumer.
PowerColor Fighter RX 6600
In this case we are faced with a manufacturer that has revealed not one, but two custom models of the new RX 6600, the first being the PowerColor Fighter RX 6600, which is based on the specifications of the AMD base model like the previous MSI model and therefore does not differ much in terms of performance or to the point that we can say that the difference is negligible if we have to opt for a or other.
The second of them is the PowerColor HELLHOUND RX 6600 which is equipped with two 100mm fans and it has an aesthetic finish that is reminiscent of silver. With regard to refrigeration, it uses a 3×6 heatpipe built in nickel and a cupro-nickel alloy base which increases the heat dissipation capabilities of this model. All this is also seasoned with 5 + 1 phase VRM with DrMOSHigh-quality, solid capacitors made from high polymers, giving the user leeway to overclock this graphics card and take advantage of the additional 18W the PCI Express port provides that the base RX 6600 does not take advantage of.
ASUS Dual Radeon RX 6600
The third brand we are talking about is ASUS, of which we highlight from the outset its Dual Radeon RX 6600, which is another custom model that is based on the specifications of the standard model and like the PowerColor Fighter and the MSI MECH 2X it does not seek to fall into the hands of fans to touch clock speeds.
As you can see it is another dual fan graphics card and it has to be said that ASUS has made it shorter than usual in exchange for gaining some height, since its measurements are 243 x 132 x 48 mm. What ASUS is looking for is to be able to place its graphics card in those boxes with less available space, which are used in many designs created by users in which graphics cards of this size are usually installed.
As for the rest of its specifications we have four video outputs: 1 x HDMI 2.1 and 3 DisplayPort 1.4a outputs.
GIGABYTE EAGLE RX 6600
The last model of the RX 6600 Custom that has caught our attention is the GIGABYTE EAGLE, which is the only one in this comparison with three fans, but in return it is narrower than other models when measuring 282 x 113 x 41 mm. Otherwise it has the same specifications as the EAGLE RX 6600 XT model that appeared a few weeks ago with its three 80mm Windforce 3X fans long each one where the two exteriors move in the opposite direction than the central one. In terms of its video outputs, GIGABYTE has gone a different path from the rest, replacing a DisplayPort 1.4a port with a second HDMI 2.1 output.
