Radeon RX 480 Video Card Review

We tested the most recent video card from AMD: the Radeon RX 480, based on the new Polaris architecture, focused on the mainstream market and virtual reality. Let’s see how it performed in our tests.
The Radeon RX 480 is based on the “Ellesmere” chip, which is part of the new Polaris architecture. It is manufactured under 14 nm lithography, with tridimensional transistors, also called “FinFET”, which allows less energy consumption than the earlier generation, whose chips where manufactured under 28 nm process.
The Radeon RX 480 chip has 2,304 cores, divided in 36 compute units, works with base clock of 1,120 MHz and boost clock of 1,266 MHz, has a 256 bit memory bus and TDP of 150 W. According do AMD, it supports FreeSync, Vulkan, VR Premium, and DirectX 12 technologies.
About video memory, the Radeon RX 480 was launched in two versions: with 4 GiB of GDDR5 RAM running at 7 GHz (224 GiB/s bandwidth) and 8 GiB of GDDR5 RAM running at 8 GHz (256 GiB/s bandwidth). According to AMD, other manufacturers can offer models with different memory speeds, but not under 7 GHz. The suggested price in the USA is USD 199 for the 4 GiB model, and USD 239 for the 8 GiB version.
The card we tested is the AMD reference model, with 8 GiB of memory. Figure 1 shows the Radeon RX 480 we tested. Notice that its designs resembles to the Radeon Fury X, which we already tested.

Figure 1: the Radeon RX 480

The 4 GiB Radeon RX 480 is placed on the price of the Radeon R9 380X (also with 4 GiB or memory), while the 8 GiB model is placed between the Radeon R9 380X (with 4 GiB) and the Radeon R9 390 (which has 8 GiB of memory). There is no direct competitor from NVIDIA in this price range, and the closest products are the GeForce GTX 960 (USD180 with 2 GiB of memory) and the GeForce GTX 970 (USD 290, with 4 GiB).
Therefore, we decided to test the Radeon RX 480 versus the GeForce GTX 960 and the Radeon R9 380, which we tested recently. Besides that, we also included a GeForce GTX 970.
Keep in mind, however, that all the three video cards included in this test are factory overclocked. The Zotac GTX 970 (model ZT-90101-10P) has a 3% overclock on the GPU, the HIS Radeon R9 380 is 2% overclocked, and the Gigabyte G1 Gaming GTX 970 (GV-N960G1 GAMING-4GD) has an overclocking of 11%. Thus, the comparison to other models, with different clock rates, can have different results.
In the table below, we compare the main specs from the video cards we included in this review. Prices were researched at Newegg.com for this article.

Now let’s take a closer look to the tested video card.

The card is 9.4 inches (240 mm) long and uses two slots. It has a centrifugal fan, which is a good choice because it blows the hot air outside the case, and allows the slot contiguous to the card do be used without spoiling the video card refrigeration.
Figure 2 shows the video connectors of the Radeon RX 480. It brings three DisplayPort 1.4 and one HDMI 2.0 connectors.

In Figure 3 you see the top of the card, where there is a six-pin PCI Express power connector.

Figure 4 unveils the end of the card, which is closed.

Figure 4 shows the solder side of the RX 480. There are no memory chips on this side. Besides that, it shows that the PCB is shorter than the cooler.

Figure 5: solder side

Figures 6 and 7 show the cooler of the Radeon RX 480. The cooler consists on three main parts: a plastic cover, that directs the air flow to the heatsinks and the outside the case, the GPU radiator, made of aluminum with a copper base, and a big metalic piece that cools the memory chips and the voltage regulator transistors.

Figure 7: the Radeon RX 480 with the cooler removed

In Figure 8 you see the RX 480 without the cooler. There are eight memory chips. As we mentioned before, the card itself is smaller than the cooler, being only 7.1” long. So, it is possible that some manufacturers offer even shorter cards.

[nextpage title=”Conclusions”]
Recently, when we compared the Radeon R9 380 and the GeForce GTX 960, we concluded that AMD still offers competitive video cards on the mainstream segment. With the launch of the first video card from Polaris architecture, that uses a 14 nm manufacturing process, the brand is even more solid on this segment.
Compared to the GeForce GTX 960 (which is the closest NVIDIA video card in terms of price), the Radeon RX 480 was significantly faster, delivering also performance in all the games we tested. AMD also improved its technology compared to the Radeon R9 380, offering more performance with a smaller TDP, which also means less heat and noise.
Actually, the Radeon RX 480 obtained, in our tests, a performance comparable to the GeForce GTX 970, which is a more expensive video card, thus offering a better cost/benefit ration than the NVIDIA model.
With all this, the Radeon RX 480 is an excellent deal for anyone who is looking for a mainstream video card, capable of running recent games in Full HD and maximum quality with high framerate, or even at 4K.
