Radeon PTX Might Be AMD’s Bold New Name for RDNA 5 GPUs

Radeon PTX could be the new face of AMD’s graphics lineup. With RDNA 5 on the horizon, AMD seems ready to rebrand and refocus on path tracing.

Radeon PTX branding could target NVIDIA’s ray tracing crown

AMD may finally be cooking up a proper branding response to NVIDIA’s RTX series. According to leaks and early discussions in the hardware community, AMD’s next-gen RDNA 5 GPUs might launch under the name Radeon PTX, with “PT” pointing to Path Tracing.

If true, it’s a deliberate echo of NVIDIA’s RTX shift, but this time, AMD’s angle leans hard into future-looking visual tech. Ray tracing was step one. Path tracing is the real target.

RDNA 5 aims for more than just gaming

Early specs suggest RDNA 5, including the AT3 and AT4 chips, will bring major upgrades beyond raw performance. These GPUs are expected to use TSMC’s N3 nodes, include up to 48 compute units, and support PCIe Gen5 with high-speed LPDDR6 memory.

Here’s a quick breakdown of what’s leaked so far:

Alpha Trion 3 (AT3)

48 CUs, 20MB L2 cache
384-bit LPDDR6 or 256-bit LPDDR5X memory
Estimated performance: RTX 4070–RX 9070 range
Massive memory capacity potential (up to 512GB)

Alpha Trion 4 (AT4)

24 CUs, 10MB L2 cache
128-bit LPDDR5X memory
Estimated performance: RTX 3060–RTX 4060 range
Up to 128GB VRAM possible

Radeon PTX could appear in 2027

Reports suggest that AMD might launch the Radeon PTX lineup alongside RDNA 5 GPUs in 2027. The new naming would help define the generation’s focus: pushing path-traced rendering as the standard, not the future.

It’s also expected that AMD will tie this launch closely to next-gen consoles. Both Sony and Microsoft are reportedly working with AMD on custom APUs for the PlayStation 6 and next Xbox, built on RDNA 5 tech and Ryzen architecture.

Radeon PTX branding might not land smoothly

Of course, if AMD really does pivot to a PTX name, there’ll be plenty of noise. Critics may call it a derivative of NVIDIA’s RTX, and some fans might push back on the naming similarity. But if the performance backs it up, AMD could flip the narrative, especially if it shows a real edge in path-traced gaming.

AMD has reason to bet on Radeon PTX

Ray tracing is here. Path tracing is coming. With RDNA 5 rumored to leap ahead in lighting performance, Radeon PTX gives AMD a name that reflects the shift. If NVIDIA defined the RT era, AMD might just want to own the next one.
