omparing core counts between AMD and Nvidia GPUs doesn’t provide much useful information. Although the RX 6900 XT has less than half the stream processors as the RTX 3090 has CUDA cores, that doesn’t mean the 6900 XT is half as quick. We can make more useful comparisons in clock speed and memory.
The RTX 3090 is king on the memory front, with a staggering 24GB of GDDR6X memory. The 6900 XT has a more modest 16GB, though it’s only GDDR6. GGDR6X has bandwidth improvements. However, combined with AMD’s 128MB of Infinity Cache, the RX 6900 XT is able to achieve much higher bandwidth, at least according to AMD’s numbers.

In-game, AMD claims the RX 6900 XT can match the RTX 3090 in most titles. Its benchmarks show an improvement in Forza Horizon 4 and Battlefield V. Some games run slightly worse on AMD’s hardware, though, including Wolfenstein: Young Blood and The Division 2. Manufacturer benchmarks aren’t usually the most reliable, so we’re remaining skeptical until we see third-party results.
Frames per second doesn’t tell the full story. The RX 6900XT is getting some help from Rage Mode a one-click overclocking utility and Smart Access Memory in AMD’s benchmarks. Smart Access Memory is a new feature for RX 6000-series cards that allows a Ryzen 5000 CPU and 500-series chipset to utilize the GPU’s ultra-fast GDDR6 memory. According to AMD, using both can offer up to a 13% performance improvement.

If you want the absolute pinnacle of graphics performance, the RX 6900 XT and RTX 3090 have it, and nothing else comes close. They each have more memory and more raw GPU performance than anything either company has made before. As powerful as they are, though, they have big differences in features and price, which could sway you one way or the other.

It’s time for the most epic of showdowns between the contemporary kings of the GPUs. Which will emerge victorious? The Nvidia RTX 3090 debuted on September 1 alongside the RTX 3080 and 3070. Boasting features that will appeal to workstation and professional owners, it was also marketed as a gaming card and offers the greatest performance of the three. Its price tag was even greater, however, sitting at $1,499 on its September 24 launch date.
If you managed to buy it at that price, you were lucky, because stock was abysmal, and price gouging sent its cost rocketing, reaching at least $2,000 on eBay for even the Founders Edition. That’s likely to remain the case until spring 2021, when Nvidia promises big orders it’s made since will be completed. The RX 6900 XT was announced on October 28 alongside the RX 6800 XT and 6800. Its price was a far more modest $999. It’s set to be available for sale on December 8, and AMD has taken steps to avoid scalping at launch. Whether that makes a difference for a card that is likely to be extremely popular remains to be seen
