HOW TO CHOOSE
MI325X vs MI350X
On paper - MI325X (CDNA 3): 256 GB HBM3e, 6 TB/s bandwidth, 1,000 W (OAM). MI350X (CDNA 4): 288 GB HBM3E, 8 TB/s bandwidth, 1,000 W (OAM, air-cooled; MI355X 1,400 W liquid). The adjacent-generation AMD question: CDNA 3 refresh versus CDNA 4 - whether the newer chip's memory and compute jump beats the 325X's panel discount.

MI325X VS MI350X - FAQ
Which is cheaper to rent, MI325X or MI350X?
By today's published on-demand rates: MI325X starts at $1.590/GPU/hr (median $2.00, 4 providers) and MI350X starts at $4.000/GPU/hr (median $4.00, 1 providers). The cheapest live listing is the MI325X at SpotGPUs. Figures recompute from the panel on every refresh.
MI325X or MI350X - which should I rent?
MI325X: The MI325X is the memory-maximized refresh of the MI300X: same CDNA 3 compute, a third more HBM3e at 256 GB. MI350X: The MI350X is AMD's fourth-generation Instinct flagship: 288 GB of HBM3E at 8 TB/s with FP16 throughput at 2.3 PFLOPS, matching the MI355X's compute at a lower 1,000 W air-cooled power envelope. The side-by-side spec table and live price rows above give the full picture.
