Compatible ROCm versions
Same Navi 48 die (gfx1201) as the RX 9070 XT, so it shares that card's ROCm support from 6.4.0 (2025-04) onward — roughly one month after launch, the fastest launch-to-support turnaround of any consumer Radeon in this collection.
fp16TFLOPS (145, dense) and fp8TFLOPS (289, dense) are both directly published, each with an explicit "with Structured Sparsity" variant (289 / 578) recorded in the ...Sparse fields — AMD publishes the dense figure as the headline and sparsity separately, the opposite of NVIDIA's convention, so no halving is applied here. int8TOPS/int8TOPSSparse mirror the FP8 figures exactly (289/578); int4TOPS is listed but its sparsity variant (1,156 TOPs) has no schema field. matrixCoreCount uses the page's "AI Accelerators" count (112).
Same 16 GB / 640 GB/s memory configuration as the 9070 XT, at lower clocks and 220 W instead of 304 W — for VRAM-bound local LLM work the two cards are closer than their compute figures suggest.
peakClockMHz uses the published Boost Frequency ("Up to 2520 MHz"), not the 2070 MHz Game Frequency. tdpWatts is the published "Typical Board Power (Desktop)". AMD's product page publishes no Launch Date field; launchDate (2025-03-06) comes from AMD's own RDNA 4 launch press release of 2025-02-28, which states availability beginning March 6, 2025. AMD publishes no MSRP on the spec page, so msrpUSD is omitted.
