Gigabyte Radeon RX 6600 XT Eagle 8G graphics card review


The Gigabyte RX 6600 Eagle features a large WindForce 3X cooling solution with an aluminium fin-stack heatsink that’s fed heat by three copper heat-pipes that make direct contact with the GPU at the base. This heatsink is ventilated by three 100 mm fans. 


The Eagle measures 289 x 112 x 38mm and tips the scales at 674g (those are both our measurements), which is longer but shorter and slightly thinner than the Sapphire Pulse. The ASRock Phantom by comparison weighs 898g and measures 306 x 131 x 47mm, easily the largest of the three RX 6600 XT cards. If you have a sufficiently-long mini-ITX case, the Gigabyte Eagle might be a good fit.


it includes two HDMI 2.1 ports. While nearly all gaming monitors still tend to prefer DisplayPort 1.4 — it can do 4K at 144 Hz with DSC, and FreeSync / adaptive sync is more commonly supported over DP — HDMI 2.1 technically offers superior specs. You can read more about DisplayPort vs. HDMI, but either one should be sufficient for typical gaming use, particularly on a 1080p display,


Considering the incredibly low 65°C, I feel Gigabyte could have allowed slightly higher temperatures, like 70°C, which won’t affect longevity or anything else, but achieve better noise levels. It’s good to see that idle fan stop has become a mandatory capability nowadays even in this segment—the RX 6600 will shut off its fans in idle, desktop work, and internet browsing.

Fan speed

The smaller fans on the Gigabyte Eagle, combined with a relatively lightweight heatsink, ultimately required substantially higher RPMs to keep the card from overheating. Where the ASRock and Sapphire cards both land around 1300 RPMs in Metro and FurMark (give or take), the Gigabyte card runs the fans at over 2100 RPM. 

Fan noise for the Gigabyte Eagle was 44.4 dBA while gaming, about 7dB louder than the ASRock Phantom and Sapphire Pulse. Again, that’s not incredibly loud — RTX 3070 Ti and above tend to land at 50 dB or more.

Power Consumption

Single-monitor idle power consumption is amazing, just 2 W is really impressive and the best result we’ve ever seen. Typical for AMD is that they’re running the memory at full speed when two monitors are connected—in that situation, we see 20 W, much higher, but not that bad compared to many other cards on the market.

Gaming power draw of just 131 W is extremely impressive, especially considering the performance offered. The Gigabyte RX 6600 is one of the most energy-efficient graphics card we ever tested.


The appeal of overclocking has waned alongside reduced headroom on modern parts, so it is surprising to find that entry-level Navi 23 GPUs show better willingness than most. The caveat on Radeon RX 6600 is that memory is limited to an effective 15.2Gbps.

+Strong 1080p performance+Great thermal efficiency+Low power consumption


-Should be cheaper-Only slightly better than the RTX 3060

For rock solid 1080p gaming, you can’t go wrong with the AMD Radeon RX 6600 XT. Not only is the card a great performer, but it doesn’t use a lot of power so you can install it in a system with a smaller PSU. Because of its great thermal efficiency, you also don’t need a super expensive water cooling system built into your PC. Unfortunately, it is a bit pricier than the Nvidia GeForce RTX 3060, its direct competition, and doesn’t come with ray tracing.

+Excellent 1440p performance+Ray tracing+Lightweight card with no sag


-Ray tracing performance is weak-No FidelityFX Super Resolution

Those comfortable messing with your BIOS and looking for a 1440p graphics card that’s slightly more accessible, price-wise, will appreciate AMD’s latest high-end offering. This Nvidia GeForce RTX 3060 Ti rival delivers a solid 1440p performance with ray tracing to boot. It comes at the right time as well, with 1440p gaming monitors’ growing popularity. Its price is a bit closer to the more powerful RTX 3070, but if you’re an AMD fan, it’s still an excellent contender.

+Excellent performance+Finally, AMD ray tracing


-Divisive design

If you think AMD is still stuck in the budget and mid-range markets, think again. The AMD Radeon RX 6800 marks AMD’s return to the high-end graphics card market, and it’s a premium ace without the incredibly premium price. This GPU delivers a solid 4K gaming performance and impressive ray tracing at 1440p, while being a better value than its direct rival, the RTX 3070, thanks to its VRAM. Plus, AMD’s Smart Access Memory technology will make it even faster.
