AMD Radeon RX 10900 XT: the future RDNA 5 graphics card that aims to outperform the RTX 6090 by 2026

The latest serious leaks finally mention a maximum of 96 CU for the RX 10900 XT , with a bus 512-bit and up to 128 MB of Infinity Cache . Realistic figures but very ambitious.

But what catches the eye the most is its memory: 36 GB of GDDR7, clocked at 36 Gbps on a 384-bit bus. Result? A theoretical bandwidth of 1.7 TB/s, well above what the RTX 5090 offers and even on par with a hypothetical RTX 6090.

👉 To compare:

• RTX 5090 : 28 Gbps in GDDR7, bandwidth ~1.79 TB/s

• RX 10900 XT (rumor): 36 Gbps, bandwidth ~1,728 TB/s

In short, AMD would hit hard on memory, a crucial area for 4K, 8K resolutions, and AI workloads.

Other important information: the consumed power The leaks speak of a TDP of 380W.

It may seem high, but when compared to the RTX 5090 and its 575 to 600W, we realize that the approach AMD's goal is to offer a better perf/watt ratio .

💡 If AMD manages to maintain this efficiency, the RX 10900 XT could appeal to all those who are tired of the mandatory 1200W power supplies on the NVIDIA side.

Everything suggests that the objective is clear: face the future GeForce RTX 6090 .

For several years, AMD has been playing cat and mouse with NVIDIA in the very high-end segment. After shining with the RX 7900 XTX and offering good alternatives to the RTX 4080 and 4090, AMD has not yet managed to dethrone NVIDIA in the ultra-enthusiast segment.

With this RX 10900 XT, the brand clearly wants to regain leadership in 2026-2027. And if the expected performances are confirmed, we could well see for the first time in a long time a Radeon faster than a GeForce "90" .

Because the RX 10900 XT will not be alone, here are the models mentioned:

The information still differs:

• Some leaks mention a launch in 2026 with the first high-end RDNA 5 chips.

• Others rather speak of 2027 , especially for the RX 10900 XT, the time AMD optimizes its drivers and its 3nm or even 2nm manufacturing processes.

In short, you will need to be patient. But one thing is certain: the hype is already there. Personally, based on all the past releases, we think it will rather late 2026 - or even second quarter 2026 .

At DropReference, we will of course be there to reference all the stocks of the future. RX 10900 XT and the RDNA 5 range as soon as they are released. As usual, you will be able to follow the price evolution in real time, compare offers from different merchants, and set alerts to not miss the drops.

In the meantime, if you want to stay informed about the best deals on current graphics cards, you can take a look at our dedicated page: all GPU stocks

If the leaks are true, here's what it could imply for us, players and creators:

• 4K and 8K gaming more accessible, without compromise.
• Ray tracing at the level (or above) of NVIDIA.
• Lower consumption that the most power-hungry GeForces.
• Potentially better performance/price ratio , AMD often having more aggressive pricing.

👉 And if AMD succeeds, we could see NVIDIA forced to lower its prices. Good news for your wallet.

For now, all of this remains conditional. But the rumors agree: AMD is preparing a monstrous graphics card with the RX 10900XT .

With its 36 GB of GDDR7 , its TDP contained at 380W and its stated goal of competing with the RTX 6090 , it could mark a turning point in the history of GPUs.

The real question now is: Will AMD be able to deliver on time, with stable drivers and real software support? Because hardware, on paper, is already dreamy.

When will the RX 10900 XT be released?

Probably between 2026 and 2027, depending on the progress of the 3nm/2nm engraving and AMD's strategic choices.

📌 How much memory will the RX 10900 XT have?

36 GB of GDDR7 at 36 Gbps, on a 384-bit bus, resulting in 1.7 TB/s of bandwidth.

📌 Will the RX 10900 XT be more powerful than the RTX 6090?

This is AMD's stated objective. The actual performance will only be known at launch, but the leaks are promising.

📌 What TDP for the RX 10900 XT?

About 380W, which would make it a more efficient card than the RTX 5090/6090.
