AMD's next-gen RDNA 5 GPU performance leaks: 5-10% faster IPC than RDNA 4 at same clocks

AMD's next-generation RDNA 5 GPU architecture will reportedly have around 10% in IPC performance uplifts over RDNA 4, according to the latest leaks.

We've been hearing about AMD's next-gen RDNA 5-based flagship GPU which should end up being called the Radeon RX 10900 XT, which will reportedly have its RDNA 5 GPU fabbed on TSMC's 3nm process node, feature up to 32GB of GDDR7 and could even be a next-gen RTX 6090 killer.

In his latest video, leaker Moore's Law is Dead says we can expect around 5-10% more IPC uplift from RDNA 5 over RDNA 4 in rasterization, while ray tracing performance should be a little higher.

This is in a direct Compute Unit (CU) comparison between RDNA 5 CUs and RDNA 4 CUs without any clock speed increases, with improvements coming from AMD using the same power consumption on RDNA 5 CUs as the current RDNA 4 CUs.

AMD is also able to scale performance beyond 64 CUs that we see on RDNA 4, to over 100+ CUs on RDNA 5, which could lead to monster new gaming GPUs and workstation GPUs based on RDNA 5 in the years to come.

AMD's next-gen RDNA 5-based flagship Radeon RX 10900 XT (or whatever it's called) has been rumored with the "AT0" die with 154 CUs of RDNA 5 inside, with 36GB of GDDR7 with up to 1.72TB/sec of memory bandwidth and a 380W, with an equivalent GPU performance as NVIDIA's next-gen GeForce RTX 6090. This was leaked by MLID not too long ago, with the huge 154 CUs being a massive upgrade over the 64 CUs inside of the flagship RDNA 4-based Radeon RX 9070 XT.

Under that, will be the Radeon RX 10700 XT with a purported 64 CUs of RDNA 5, putting its performance somewhere between the RTX 5080 and RTX 4090, but with a rumored target price of under $550, which would be fantastic for Radeon RX gamers in the future.
