AMD RADEON RX 6600 XT, analysis: an interesting GPU for 1080p gaming


We present the review of the new card GIGABYTE GAMING OC PRO 8G with the graphics processor AMD RADEON RX 6600 XT, an affordable chart within the current panorama and intended for gaming 1080p with state-of-the-art technology.

This new entry-level AMD 6000 series GPU has full support DirectX 12 Ultimate, under this platform we have key next-gen technologies such as Mesh Shaders, Sampler Feedback, VRS and support VRR thanks to the connectors HDMI 2.1. Also as an extra this graphic has acceleration for the new codec AV1, both for decoding and encoding, support DirectX Raytracing (DXR) and the visual improvements that AMD FidelityFX offers us. We also have the new system Fidelity Super Resolution to improve performance by rendering from a lower resolution without losing much detail. Let’s see how this new AMD graphics solution defends itself and what it offers compared to its rivals.

This new architecture 2X ships (Big Navi) promises us a theoretical improvement of the 2x performance with respect to RDNA in addition to integrating technology at the hardware level compatible with Raytracing thanks to the bookstore DirectX X12 Ultimate and the use of the specific hardware integrated in the lightning accelerators.

One of the most interesting points of the new GPUs AMD Radeon RX 6000 Series is the inclusion of Infinity Cache Inside the graphics processor core, this cache of 32 MB on this 6600 GPU enables a performance improvement of up to 2x in certain scenarios. Thanks to this system AMD can mount GDDR6 memories obtaining results that can compete with the GDDR6X, much more expensive and with stock problems.

Card details

The graphics card that we are going to specifically test is the GIGABYTE GAMING OC PRO 8G which has a large heatsink with three cooling fans 79 mm that work with semi passive system that if it detects a low workload, it stops them so they will not emit any noise. At the top of the GIGABYTE logo we have an RGB led.

We have one 8-pin connector that give enough energy for your limit of 160 W, the recommended power supply for the equipment where we mount this GPU is 500 W. As for connectors we have an output HDMI 2.1 with resolution support 4K @ 120fps which is compatible with VRR y FRL, plus two connectors DP 1.4 with DSC compression support and a connector in USB Type-C with video output.

Testing hardware

We connect all the components to our motherboard with the new chipset B550 and both the CPU AMD Ryzen 5 5600X like the GPU AMD RADEON RX 6600 XT.

To assemble the set we have opted for the following elements:

PERFORMANCE TEST

GPU Settings

We put the GPU to the test GIGABYTE GAMING OC PRO 8G with the most popular games with their default settings. This graphics card with processor Navi 23 made in 7 nm defaults to 2000 MHz, in game mode to 2359 MHz and in Boost mode it reaches the 2607 MHz. We have built-in memory of 8 GB GDDR6 who work at 16 Gbps and has a data bus of 128 bit, has 2048 unified shaders, 64/128 ROPs / TMUs, supports connectivity PCI Express 4.0 and system PCI Express Rezisable BAR.

Control software

In the control software it should be noted Radeon Adenalin which allows us to launch our games with package specific optimizations FidelityFX What Super Resolution, Anti-Lag, Chill, Boost, image Sharpening and timing adjustment for FreeSync or similar. Some of these options are only aesthetic or help us in certain games, we also have specific profiles for each type of game or we can customize them to our liking.

With this GPU we are going to test the new performance improvement system Super Resolution, an AMD alternative to the NVIDIA DLSS system with the positive point that it will be a universal system that will run on DirectX 12 Ultimate. For now there are few compatible titles, but it is expected that we will have many more available soon, we will make a special article about it with more information and performance tests.


Test of performance

We perform our performance tests on the AMD RADEON RX 6600 XT with various resolutions in the highest available quality and we also tested the lighting system in real time on the titles that support this system. How can we see the optimal performance is 1080p, some results that we will see how they will improve when applying the system Super resolution In another article soon, an interesting point to activate Raytracing and compensate for the loss of performance. We can get more performance by combining this GPU with a processor AMD Ryzen 5000 gracias a AMD Smart Access Memory (SAM).

  • Adjustments in test: Ultra quality available / No vertical sync.
  • Competence: By price it is with its direct rival NVIDIA RTX 2080 that depending on the title and resolution.
  • Raytracing performance: Performance loss of approximately 50%.

Overclock, consumption, thermals and noise

We can perform OC on the graphics card AMD RADEON RX 6600 XT although it is quite limited and we cannot exceed 2509 MHz. three 79mm semi-passive fans of the GPU in desktop mode are stopped, which is very appreciated for working or watching multimedia content in silence. The thermals at all times they remain very low, we do not have to fear for that aspect and consumption is also very contained.

  • Consumption, thermals and noise: Reposo 61 W – 48 ºC – 0 dBa / Máximo 165 W – 64 ºC – 56 dBa.
  • Overclock: Base 2000 MHz / 2359 MHz Boost / 2607 MHz Gaming.

VIDEO AND AUDIO TEST

Playback test

In the video playback section the GPU AMD RADEON RX 6600 XT has a VPU which has hardware support for codecs HVEC, VP9 Y AV1, in this processor we have video support 8K Y 10 bit de color. We also have compatibility HDR although on our screen we have had to try various settings until we reach the appropriate screen mode to activate this function in Windows. This card is also compatible with Dolby Atmos y DTS X. Performance with advanced video formats can vary between code and Windows serial player, KODI is usually better.

CONCLUSIONS AND PURCHASE LINKS

Opinion

Once we have tested the graphics card GIGABYTE GAMING OC PRO 8G with the processor AMD RADEON RX 6600 XT we can say that we are facing a product oriented 100% to users who are looking for a graphics card to Gaming 1080p with good performance at a reasonable price. A hardware that benefits from technology RDNA 2 to get the most out of your tools FideliyFX, FreeSync The SAM, an ideal hardware to combine with AMD Ryzen 5000 processors. A highly limited GPU for the future in Raytracing functions or with resolutions higher than FullHD, small thanks to integrating Super Resolution little by little in more titles we will be able to squeeze more the hardware.

The GIGABYTE GAMING OC PRO 8G that we have used in this analysis offers us low consumption, good loudness and a semi-passive fans they allow you to keep our PC quiet in many common usage scenarios. As we have seen during the gaming sessions we have a very contained consumption and a good acoustic level. The overall performance of the card for 1080p is good and in this new generation it has no competition in its sector.

We can say that the card GIGABYTE GAMING OC PRO 8G with the graphics processor AMD RADEON RX 6600 XT offers us a Interesting option for 1080p players with the latest technology. Unfortunately in the speculative period that we are going through and without low-end graphics cards we have many more options in this range.
