The Internet has recently exploded with information about the Radeon RX 6600 XT graphics card. What journalists do not cover. First and foremost, readers are interested in actual game performance. The GeForce RTX 3060 was chosen as a competitor, which turned out to be 5% slower than the new product. We were told that purchasing a Radeon RX 6600 XT for $400 is almost the most profitable investment in life, but finding such a card for less than 700 rubles was unrealistic in Russian retail.
Mining effectiveness is also actively debated. According to reports, the novelty is the best card for Ether mining due to its high energy efficiency. All of this is highly speculative and frequently implausible. Perhaps you simply need to make the appropriate comparison.
5700XT vs 6600XT: Specifications
The RX 6600 are built on AMD’s RDNA 2 architecture, so we can draw some direct comparisons between them based on specs. Although the RX 5700 XT is based on last-generation architecture, its specifications reveal some interesting details compared to the newer cards.

The Radeon RX 6600 XT is AMD’s latest mainstream GPU release, and it is expected to hit store shelves the day after this review goes live, on August 11, for immediate availability. The $380 MSRP is only an estimate of the product’s actual street price.
Due to scarcity, cryptomining, and scalping, expect to pay a hefty premium. If we use the 6700 XT as a benchmark, the 6600 XT should cost around $600. We’ll save the detailed retail pricing discussion for later when we look at the cost per frame data, but for now, let’s focus on the claimed MSRP, which shows the 6600 XT is 21% cheaper than the 6700 XT.

With the 6600 XT, we’re looking at new silicon because the Navi 23 GPU is based on a 237mm2 die with 11.1 billion transistors, nearly a billion more than the older 5700 XT. 32 compute units with 2048 stream processors, 128 TAUs, and 64 ROPs are available. Compared to the 6700 XT, this represents a 20% reduction in cores and TAUs.
The memory subsystem on the 6600 XT has been significantly downgraded, dropping from a 192-bit wide bus to a 128-bit memory bus. This 33% reduction means that, despite using the same 16 Gbps GDDR6 memory, the bandwidth has also been reduced by 33%, dropping from 384 GB/s to just 256 GB/s.
5700XT vs 6600XT: Gaming Performance
The RX 6600 XT and 5700 XT are solid 1080p cards, capable of running many 1440p games at 60 frames per second (fps).
We tested all three cards in a system with an Intel Core i9-10900K, 32GB of RAM, and a 2TB Crucial MX500 SSD. If you have a recent Ryzen processor, Smart Access Memory is available for the RX 6000 cards, which can boost frame rates by 5%-10% in supported titles.
3DMark Time Spy gives a good overview of how the cards compare. The RX 6600 XT and RX 5700 XT were close, with about an 11% difference in favor of the RX 6600 XT. With a 22% advantage over the RX 6600 XT and a 33% advantage over the RX 5700 XT. Read; AMD unveils Ryzen PRO 6000 Business Laptop Processors
They averaged 100 frames per second at 1080p Ultra High settings in one of our most demanding benchmarks, Assassin’s Cred Valhalla. That’s significantly higher than the 6600 XT’s 83 fps average and the RX 5700 XT’s 82 fps average.
At 1440p Ultra High settings, all three cards maintained frame rates above 60 fps. The RX 6600 XT and RX 5700 XT achieved 60 and 62 frames per second, respectively.
5700XT vs 6600XT: Ray tracing and FidelityFX Super Resolution
Hardware-accelerated ray tracing is a big perk of the RX 6600 XT and RX 6700 XT. Ray-traced lighting and shadows can be enabled in supported titles such as Resident Evil Village and Control. You can’t with the RX 5700 XT.
Just because you can, though, doesn’t mean you should. Although some games, such as Resident Evil Village, can run with ray tracing enabled, many others cannot. AMD does not include dedicated ray-tracing cores, and these complex GPU calculations can quickly degrade the frame rate.
That’s only if you’re running the game without FidelityFX Super Resolution (FSR). FSR is AMD’s version of Nvidia’s Deep Learning Super Sampling (DLSS) technology. It’s not as impressive, but it does help boost frame rates in high-stress situations (like ray tracing turned on). Read Also; AMD Radeon RX 470 Mobile Review
Because it supports ray tracing and FSR, Resident Evil Village is a great game to highlight here. Unfortunately, it is not well-represented. FSR is still in its early stages, and support is patchy. Many popular ray-tracing games do not support it, rendering the extra visual glitz largely ineffective.
That could change as more games support FSR, however. If ray tracing is important to you, stick with RX 6600 XT.
