AMD RDNA 5 and the Radeon RX 10900 XT: what's actually leaked

The interesting part of the RDNA 5 rumor isn't a spec — it's a strategy shift. After RDNA 4 (the Radeon RX 9000 series) deliberately topped out in the mid-range, AMD is rumored to return to the high end with RDNA 5, with a flagship built to go after NVIDIA's next-generation card. This page lays out what's been reported, who reported it, and which parts are speculation. If you want a card you can actually buy today, jump to our best graphics cards of 2026.

Where these "specs" come from

This matters more than the numbers. The detailed RDNA 5 flagship specs that spread across the web trace primarily to one source: YouTube leaker Moore's Law is Dead (MLID). Outlets including TweakTown, Hardware Times, and PCGamesN wrote it up (their headlines use "rumored," "may feature," and "reportedly"), and forums re-posted it. But those aren't independent leaks — they're re-reports of the same origin. As the leakers themselves note, the specs are "incredibly subject to change."

Even the card's name isn't settled: it's reported as the Radeon RX 10900 XT in most coverage, but as the RX 10090 XT in others — a good reminder of how early and unverified this is.

The two leaks don't agree

Most write-ups quote one set of numbers. In reality there are two competing leaks, and they disagree on the two specs that matter most — compute units and memory bus. We show both rather than pick a winner:

Camp A traces to Moore's Law is Dead, via TweakTown and Hardware Times. Camp B traces to leaker Kepler_L2, via VideoCardz and Wccftech. Both agree the flagship die is "AT0"; they disagree sharply on its size. Neither is confirmed. The comparison table below uses the more widely-cited Camp A figures.

The rumored RDNA 5 flagship, vs the rumored RTX 6090

The most-repeated framing is a next-gen flagship face-off. Here's the rumored Radeon RX 10900 XT next to the rumored NVIDIA RTX 6090 — both columns are unconfirmed, and neither company has announced anything:

Both columns are rumored and unconfirmed. The AMD figures trace to Moore's Law is Dead via the outlets linked above; the NVIDIA figures are covered on our RTX 6090 rumors page. Numbers may change or prove wrong entirely.

The real story: AMD returning to the high end

The headline isn't the 36 GB — it's that AMD is rumored to build a flagship at all. RDNA 4 (Radeon RX 9000) was a deliberately mid-range generation: strong value in the mainstream, no halo card chasing the RTX 5090. The RDNA 5 rumor reverses that: a large "AT0" die, roughly 154 compute units (about 10,000 shader cores), 36 GB of GDDR7 on a 384-bit bus, and a board power near 380 W — the profile of a card built to compete at the top, per Hardware Times.

On process, the leaks diverge: most cite TSMC N3P (a refined 3 nm node), while at least one report points to a 2nm-class process. Either way, the rumored positioning is the same — a genuine high-end Radeon, which the market hasn't had since the RX 7900 XTX generation.

Is it really an "RTX 6090 killer"?

That phrase shows up in a lot of the coverage, so it's worth being clear: it's a rumor about intent, not a benchmark result. No RDNA 5 or RTX 60-series silicon has been tested by anyone. What the leaks claim is that AMD is targeting RTX 6090-class performance — per PCGamesN and others — not that it has been shown to match it. AMD's recent generations have been competitive in raster and improving in ray tracing while trailing NVIDIA at the very top; whether RDNA 5 closes that gap is exactly the kind of claim that only real hardware can settle.

Release date and price

Release window: the rumors cluster on mid-2027, per TweakTown, with add-in-board partners rumored to show cards around Computex 2027; some coverage stretches it to mid-to-late 2027, and one source floats a slip into 2028. That lines up roughly with the rumored RTX 6090 timing, setting up a potential next-gen head-to-head. One wildcard: the same 2026 DRAM/memory shortage that reportedly pushed NVIDIA's RTX 60 series back could squeeze AMD's schedule too — high-VRAM GDDR7 cards are exactly what the shortage makes expensive. None of it is a confirmed date.

Price: there is no leaked or official MSRP. AMD has historically undercut NVIDIA's flagship pricing; a high-end RDNA 5 card would plausibly follow that pattern — but "plausibly" is the operative word, and there is no number to quote.

What is not confirmed (the honest list)

• Anything from AMD. No announcement, teaser, or official spec.
• The card's name. "RX 10900 XT" vs "RX 10090 XT" — even that isn't settled.
• The process node. N3P vs a 2nm-class node, depending on the report.
• Performance vs the RTX 6090. A stated target, not a measured result.
• Price and exact launch date. No credible figures exist.

We'll update this page if AMD confirms anything or a genuinely new, multi-source leak appears. Until then, it's rumor.

Frequently asked questions

When will AMD RDNA 5 (Radeon RX 10000 series) be released?

AMD has not announced a date. The most-repeated leak, originating with Moore's Law is Dead and re-reported by outlets including TweakTown, points to a mid-2027 launch, with add-in-board partners rumored to show cards around Computex 2027. Some coverage stretches the window to mid-to-late 2027, and one source suggests it could slip to 2028. None of it is confirmed by AMD.

What are the rumored Radeon RX 10900 XT specs?

Two leaks disagree. Moore's Law is Dead reports ~154 compute units (about 10,000 cores) on a 384-bit bus with 36 GB of GDDR7 and ~380 W, on an “AT0” die. Leaker Kepler_L2 (via VideoCardz) instead reports 96 compute units on a 512-bit bus. Both agree the flagship die is “AT0” but split sharply on its size; some leaks also call the card the RX 10090 XT. Every figure is unconfirmed.

Is the RX 10900 XT really an “RTX 6090 killer”?

That framing comes from the leaks, not from benchmarks -- no RDNA 5 or RTX 60-series silicon has been tested. The rumor is that AMD returns to the high end with RDNA 5 (after RDNA 4 topped out in the mid-range) and targets NVIDIA's next flagship. Whether it actually matches the RTX 6090 is pure speculation until real hardware exists.

Should I wait for RDNA 5 or buy a GPU now?

If you need a card today, don't wait on a 2027 rumor with no confirmed specs, price, or date. Buy from the current 2026 lineup. Waiting only makes sense if you already own a high-end card and are simply curious about the next generation -- and even then, mid-2027 is a rumor, not a plan.

Is RDNA 5 confirmed by AMD?

No. AMD has made no announcement, spec, or teaser for RDNA 5 or the RX 10000 series. Every figure and timeline in circulation traces to leakers and industry speculation -- chiefly Moore's Law is Dead -- not to AMD.

In the meantime: GPUs you can actually buy

A mid-2027 rumor doesn't help you build a PC today. If you're shopping now:

• Best graphics cards of 2026 — the current NVIDIA and AMD lineups, ranked by value, with real pricing.
• GPU benchmark hierarchy 2026 — where every current card lands on raster, ray tracing, and value.
• RTX 6090 rumors — the NVIDIA side of this next-gen story, tracked with the same honest framing.
• RTX 50 Super refresh — the nearer-term (and messier) NVIDIA rumor, if you're weighing a wait.
• Zen 6 vs Nova Lake — the next-gen CPU side (Ryzen 10000 vs Core Ultra 400), same CES 2027 window.
