AMD might be working on a graphics card that would beat Nvidia’s RTX 3090

A new leak suggests that AMD may have a new graphics card in the works — and it just might be more powerful than Nvidia’s GeForce RTX 3090. The rumored AMD Radeon RX 6900 XTX is said to be AMD’s fastest Big Navi 21-based card, featuring improvements both in terms of memory and clock speeds. This information was shared on Twitter in the form of a slide that contains additional information about the card.

The AMD Radeon RX 6900 XT, the manufacturer’s current top powerhouse, comes in two variants: One with a Navi 21 XT GPU, and one discarded with a Navi 21 XTXH. Regardless of the Navi GPU used, both of these graphics cards are referred to as Radeon RX 6900 XT. According to a new leak posted on Twitter by CyberPunkCat, If the leak proves to be true, AMD’s latest creation, the Radeon RX 6900 XTX, would be the third variant of this GPU. The leak suggests that AMD is working to utilize the Navi 21 XTXH and then equip it with faster memory and higher clock speeds. This would allow the card to rival, and even surpass, Nvidia’s GeForce RTX 3090.

The slide shared by CyberPunkCat shows that the RX 6900 XTX is going to have a power of 24.93 teraflops (TFLOPs), while AMD’s RX 6900 XT has 23.04 TFLOPs. RX 6900 XTX will also have a higher boosted clock speed of 2435MHz, while the RX 6900 XT has 2250 MHz. This means that the card is a straight upgrade over its predecessor, featuring both 8% more compute power and an 8% higher boost clock.

We can also expect to see a change in memory. Rumors suggest that the RX 6900 XTX is going to feature 18Gbps memory dies, providing a noticeable upgrade over the current 16 Gbps G6 chips. While the card is likely to still offer 16GB of GDDR6 memory, its bandwidth is said to be 12.5% higher at 576 GB/s.

It’s likely that a card with this kind of power is going to consume a lot of it, too. For reference, the existing Navi 21 XT GPU has a TBP of 300 watts, and this card is a definite step up. As such, it’s possible that the RX 6900 XTX is going to have a TBP of around 350W.

Releasing this GPU could put AMD at the very top of the list of the best graphics cards currently on the market. It would not only beat AMD’s own previous top card, but it would also dethrone Nvidia’s GeForce RTX 3090, which the RX 6900 XT is already on par with. However, it’s uncertain whether the Radeon RX 6900 XTX is going to be released on the consumer market.

Although the slide suggests a wider release due to the included “Expanding the AMD RDNA Family” quote, it’s possible that AMD may only distribute it to its PC and manufacturer business partners. Given the rumors that Nvidia might be working on the successor to the RTX 3090, releasing AMD Radeon RX 6900 XTX could be a smart move for the manufacturer.

You shouldn’t buy these Nvidia GPUs right now

Buying a new GPU in this generation is a bit of a tricky minefield of graphics cards to steer clear of. Sometimes, the performance is there, but the value is not; other times, you could get something much more capable for the same amount of money.

While Nvidia makes some of the best GPUs, it's certainly no stranger to that performance vs. value dilemma. Below, I'll show you three Nvidia graphics cards you're better off avoiding right now and tell you their much better alternatives.

AMD’s GPUs had a bigger year in 2023 than you might realize

It's safe to say that 2023 turned out to be a good year for the discrete graphics cards market. According to the latest data, both AMD and Nvidia saw an increase in add-in board (AIB) GPU shipments in the final quarter of 2023, and the year-to-year gains are also massive. While Nvidia still dominates the market, AMD's share is climbing steadily, and Intel remains in the shadows.

Today's round of market insights comes from Jon Peddie Research (JPR), and it's all about discrete GPUs. According to the analyst firm, discrete GPU shipments increased by 6.8% over the fourth quarter of 2023 compared to the previous quarter. This is above the less-than-impressive 10-year average of -0.6%. The year-to-year gains are even more impressive, though, as JPR notes a 32% increase compared to the final quarter of 2022, with a total of 9.5 million GPUs shipped (as opposed to 8.9 million units at the end of 2022).

Nvidia is the ‘GPU cartel,’ says former AMD Radeon manager

AMD's former senior vice president and general manager of Radeon has come out with some strong words against Nvidia. Scott Herkelman called Nvidia "the GPU cartel" in response to a story from the Wall Street Journal in which Nvidia's customers claim that it delays GPU shipments in retaliation for those customers shopping with other suppliers.

The accusation in question comes from Jonathan Ross, CEO of AI chip startup Groq, who said, "a lot of people that we meet with say that if Nvidia were to hear that we were meeting, they would disavow it. The problem is you have to pay Nvidia a year in advance, and you may get your hardware in a year, or it may take longer, and it's, 'Aw shucks, you're buying from someone else, and I guess it's going to take a little longer.'"
