AMD Radeon RX 6600 review: cut for Full HD gaming, but too high a retail price

AMD has just formalized its Radeon RX 6600, a graphics card intended for the gaming market, more particularly for Full HD gaming. What to compete with the RTX 3060?

WE love

  • Sufficient performance in Full HD
  • L’architecture RDNA2

We don’t like

  • The real price
  • Ray-tracing performance

Verdict :

Sold as a card intended for Full HD gaming, the Radeon RX 6600 fulfills this role perfectly. Its performance is sufficient to offer a decent gaming experience in this definition, whatever the graphics settings used… as long as ray-tracing is not activated. The RDNA2 architecture shows its limits here against the competition, but it is also the case of the other models of the RX 6000 Series range from AMD. The biggest downside remains the price and availability of this new Radeon: like its big sisters, it suffers from a shortage which automatically leads to an increase in its retail price in stores. We are currently very far from the recommended retail price of 339 euros …

It’s been a year since the Radeon RX 6000 Series landed, with the arrival on the market of the Radeon RX 6800, RX 6800 XT and 6900 XT. More recently, AMD’s line of graphics cards has grown with the launch of the Radeon RX 6700 XT and Radeon RX 6600 XT. It still lacked an entry-level graphics card from AMD’s catalog, sufficient to run any game in Full HD and offered at the most affordable price possible, below the RX 6600 XT. It is precisely in this segment of the market that the all new Radeon RX 6600 is placed. currently impossible to find it for less than 500 euros), will this graphics card find a place against the GeForce RTX 3060?

In order to evaluate the Radeon RX 6600 from AMD, we once again collaborated with our colleague Igor Wallossek, from German site Igor’s Lab. It is a Speedster SWFT 210 model supplied by the manufacturer XFX which serves as a support for measurements and tests.

RX 6600: the smallest RDNA2 card on the market

Based like the other models in the RX 6000 Series range on the RDNA2 architecture, the Radeon RX 6600 uses a Navi 23 XL GPU engraved at 7 nm like the other GPUs in the range. Compared to the GPU of the RX 6600 XT, we lose 4 Compute Units and go from 2048 to 1792 Stream Processors. The number of transistors and the die surface do not change, however: the Navi 23 XT and XL have 11.06 billion transistors and occupy an area of ​​237 mm². Equipped with 8 GB of GDDR6 memory (at a lower frequency, however) and 32 MB of Infinity Cache like its big sister, the RX 6600 of course benefits from the support of DirectX 12 Ultimate, from thehardware acceleration of ray-tracing and Variable Rate Shading, as well as Smart Access Memory. These technologies have already been detailed and explained in our previous file dedicated to the Radeon RX 6800/6800 XT.

With reduced GPU and memory frequencies compared to the Radeon RX 6600 XT and a lower number of Compute Units, this new RX 6600 logically displays a lower TDP than that of its big sister. However, we keep the same 8-pin power connector as on the RX 6600 XT.

The XFX card is rather light since it only displays 640 grams on the scale. The cooling system is topped by two 95mm fans and no RGB keys are present. The XFX RX 6600 is a purely dual-slot model, with dimensions of 18 x 12.5 cm. At the rear there is a classic backplate which comes to participate in the heat dissipation. Finally, HDMI 2.1 (x1) and DisplayPort (x3) outputs are available.

Note that our colleague Igor Wallossek encountered a problem with his test copy: the cooling system failed the first time it was powered on, forcing him to play Doctor Frankenstein by adapting a cooler from XFX to the card. an MSI card. We will therefore not dwell on the noise pollution or the temperatures of this RX 6600 since the cooling system is not the original one.

Full HD performance of the Radeon RX 6600

The test platform used to measure the performance of this RX 6600 includes a AMD Ryzen 9 5900X processor, an MSI MEG X570 Godlike motherboard, two 16 GB DDR4-4000 Corsair Vengeance RGB Pro memory modules (CL18-22-22-42), a SSD of 2 To (Gigabyte Aorus NVMe Gen4), a SSD Corsair MP400 of 2 To et une Be Quiet Dark Power Pro 12 1200W, all placed in a Raijintek Paean case. A watercoling system composed of an Alphacool Eiswolf (modified) and an Eisblock XPX Pro takes care of the cooling.

The Radeon RX 6600 has been pitted against models from current and previous lines from AMD and NVIDIA, from the RX 5700XT to the RX 6800 and from the RTX 2070 Super to the RTX 3070. SAM / rBAR is enabled for all models. cards that support it. The panel of games used to measure the performance of these cards includes 7 recent titles: four in DirectX 12 and three using the Vulkan API. All games have been tested and Full HD, with the highest possible graphics settings.

Overall, the Radeon RX 6600 is more or less on par with NVIDIA’s RTX 3060. It is efficient enough to offer a framerate over 60 frames per second in any Full HD game at maximum graphics settings. On the other hand, it is placed slightly below an RX 5700 XT of the previous generation, deprived it is true of ray-tracing support. Except that with only 28 RT Cores, this RX 6600 is far from being up to par in terms of ray-tracing anyway …

In Metro Exodus with its hybrid rendering, we drop to around 51 FPS on average in Full HD where the Radeon RX 6600XT, already in difficulty, was struggling to approach the bar of 60 FPS. A simple RTX 3060 exceeds this same threshold of 60 frames per second … In other words, forget the ray-tracing with this RX 6600: even if it supports the hardware acceleration of this type of rendering, it clearly does not have the shoulders strong enough to provide an acceptable playing experience.
