AMD RDNA 3.5 Powers Radeon RX 8000 for Mobile, RDNA 4 Drives RX 9000 Desktop Series

AMD's interim RDNA 3.5 architecture will power the Radeon RX 8000 series integrated graphics in "Strix Halo" mobile processors, while the more advanced RDNA 4 architecture is reserved for the higher-tier Radeon RX 9000 series of discrete graphics, according to @9550pro on X. We previously believed that AMD's Ryzen AI MAX 300 Strix Halo processors would carry an iGPU with Radeon 8000S branding. However, at the same time, we expected the Radeon RX 8000 series of desktop GPUs to have a similar branding while being powered by RDNA 4. The new Radeon naming scheme is now transparent, thanks to the latest leaks of the naming schemes and early glimpses of reference design.

The RDNA 4-based RX 9000 series will be powered by the Radeon RX 9070 XT, built on the Navi 48 silicon. This GPU represents AMD's new focus on the high-volume midrange performance segment rather than competing in the ultra-enthusiast high-end space. The architecture promises enhanced SIMD IPC performance and a specialized ray tracing solution that significantly reduces performance overhead compared to current offerings. According to All The Watts, the RX 9000 lineup is expected to include various SKUs across different performance tiers, including the RX 9060, 9050, and 9040 series. Meanwhile, the RDNA 3.5-powered RX 8000 series will serve as a refined iteration of the current RDNA 3 generation. Still, they will be exclusive to AMD's mobile segment in the form of iGPU, integrated inside Strix Halo APU. Both RDNA 4 GPUs and RDNA 3.5-based APUs are scheduled for the CES 2025 event unveiling in January.

So no High End this time?

Nice, finally AMD copied Nvidias branding, what a game changer.
AleksandarKultra-enthusiast high-end space
Dude just stop, just because the ex Radeon Boss called it “ultra enthusiast” you don’t have to do that. “enthusiast” is nonsense anyway, it’s just “High End” nothing changed. ;)

All that being said, can’t wait for the numbers especially RT performance and then later FSR 4 (first AI FSR).

they can call it whatever they want, what matters is perf/price

The only thing I want to know is if when they'll bring Strix or Strix Halo into a Desktop APU.

That was known already for perhaps a year if not more.

Nope, AMD wont help you get a cheaper Ngreedia GPU.

I wish AMD had the performance crown at least once to show everyone that Nvidia still wouldn't lower their prices by 1 single cent.

Unlikely, they want you to buy a card instead, but if, it would be expensive anyway. It'll be expensive in laptops. This is Strix Halo, Strix Point will probably come to desktops.

The last time that an AMD graphics card truly shook the market was probably when Polaris came out at $199, some 8 years ago. Nvidia's dominance has been pretty much uncontested since then. Hell, it's like AMD itself gave up trying to cater to their core audience, seeking loftier ambitions that they have ultimately and repeatedly failed to match or achieve.

This old press deck resonates more with the AMD customer base than anything else they have released since

I'm hopeful that with this new generation they learned their lesson and return to what made Polaris great. No pretentious BS, no lofty promises - just an unassuming GPU for the average consumer.

No no, RX 6000 times was hard for Nvidia, they had to push the bounderies (3090 Ti, 3090), and release the biggest chip as an cut down xx80, which they usually never did (GTX 780 was last time before that). This was all because AMD was very competitive with RTX 30 series. Since RTX 40 series they are weakly contested at high end again, 4090 has 0 competition. 4080 has middling competition and AMD's marketing was weak, which always helps Nvidia just dominate the market. It's not like Nvidia has better graphics cards everywhere, just high end.

Nvidia always was strong with marketing (so *was* intel, isn't anymore), AMD, not really. Ryzen yes, Athlon, okay-ish, Radeon, no. Marketing is key and very important. Mind share is very important and part of marketing.

No, it really was not hard... back then both companies were pretty much selling any cards that they could manufacture due to Covid and the crypto boom, but you forgot that NV was using the Samsung foundry and had its entire supply to itself, while AMD was pretty much prioritizing the server market as they always do. Most of AMD's silicon supply tends to go to the extremely high margin EPYC business, back then it got to the point that they cancelled the Zen 3 Threadripper processor so they could sell these processors as EPYC instead. It does need pointing out that Radeon is a distant last in node allocation, which reflects on the fact that older node Radeons are the only ones you will find in healthy supply, not because there is super high demand for newer cards but because AMD simply does not manufacture that many.

The 6900 XT performed well, but it had many caveats against its competition (such as the notoriously inferior media encoder), and even performance-wise it has the same problem of the RTX 4080, its narrow bus and overreliance on the last level cache tends to hurt its performance very badly at high resolutions due to low real memory bandwidth. RT then is out of the question, it performs about the same as the RTX 2080 Ti from a generation prior, which was one of the areas where RTX 3090 made insane strides over the previous generation thanks to it having terabyte-class memory bandwidth. It is still probably the best architecture to come out of AMD in a very long time, but the software, market conditions and gaming trends did not stack favorably towards it.

Let's not forget that this was still a thousand dollar MSRP graphics card. AMD buyers are in massively in the lower midrange segment up to $300, they are the kind of people who resent spending money on superfluous things and fueling the so-called greed.

AMD cant help, that's why.

Sadly for consumers, Blackwell will be another nail in the coffin for high end GPU competition, nvidia will be on top alone.

AMD knows this, they don't even bother trying.

Dr. DroNo, it really was not hard
Not about selling numbers, about how hard they had to push themselves. ;) Yes it was. In RTX 40 series, 1) xx80 isn't big chip anymore, it's kinda small, 2) 4090 is cut down and still easily fastest, completely different story. 3090 was nearly full chip, 3090 Ti was full chip, but mainly faster through stock overclock, which was extra 100-200W (= higher average clocks) depending on workload, basically a 3090 on steroids, just to beat AMD. Not only did Nvidia not bring nearly full chip in xx90 this time, no, they also didn't refresh it with a stronger one, like last time. The 4090 is more comparable to what Titan was in GTX 700 times, than to RTX 20/30 times, clearly cut down, huge vram, expensive. With the difference, this time AMD did not push Nvidia to bring a 780 Ti (or 4090 Ti, which would've been this version). ;) Instead Nvidia sold the full chips as workstation chips for triple price somewhere else.

They are probably gonna return to high end with UDNA though, they are gonna unify server + consumer GPU branches, therefore making it easier for them to compete again, basically, more like what Nvidia does for a long time. The branched way didn't work out for AMD GPU, it makes a lot of things (including software) too complicated to cater for, and too much work / $ for two very different arches. Nvidias is more stream lined, and really, they always were. Big architectural changes with Nvidia are kinda rare. This is one reason why Nvidia driver issues were rare. You barely change anything = the software is easier to maintain. Nvidia mainly bet on improvements instead of overhauls, AMD did a lot of overhauls, they should keep it to a minimum, it's just easier and better for themselves (and really everyone). This will be what AMD will try to do with UDNA.
