AMD Radeon RX 9070 XT 16GB
Overview
The Radeon RX 9070 XT is the flagship of AMD's RDNA 4 generation and the first Radeon card whose AI numbers are worth quoting next to a datacenter part. Its 64 compute units carry 128 second-generation AI accelerators that add native FP8 in both E5M2 and E4M3 encodings plus 2:1 structured sparsity, neither of which RDNA 3 had, which is why dense FP8 lands at 389 TFLOPS against 48.7 TFLOPS of FP32 vector, a ratio of eight rather than the two RDNA 3 managed. Memory is the constraint rather than compute: 16 GB of GDDR6 on a 256-bit bus at 640 GB/s is enough for most single-card inference work but not for a large model in full precision. Board power is 304 W through two 8-pin connectors on a PCIe 5.0 x16 interface. AMD publishes no FP64 or BF16 rate for this part, and this catalog does not invent one.
Performance
Peak theoretical throughput by precision type
| Precision | Dense | 2:4 Sparse |
|---|---|---|
FP64 | No verified data available | Structured sparsity is a tensor-core feature; this vector precision has no sparse form |
FP32 32-bit floating point | 49TFLOPS | Structured sparsity is a tensor-core feature; this vector precision has no sparse form |
TF32 | No verified data available | The part supports 2:4 sparsity, but the vendor publishes no sparse figure for this precision |
BF16 | No verified data available | The part supports 2:4 sparsity, but the vendor publishes no sparse figure for this precision |
FP16 16-bit floating point | 195TFLOPS | 389TFLOPS |
FP8 8-bit floating point | 389TFLOPS | 779TFLOPS |
FP6 | No verified data available | The part supports 2:4 sparsity, but the vendor publishes no sparse figure for this precision |
FP4 | No verified data available | The part supports 2:4 sparsity, but the vendor publishes no sparse figure for this precision |
INT8 8-bit integer | 389TOPS | 779TOPS |
INT4 4-bit integer | 779TOPS | 1,557TOPS |
Per watt divides the dense figure by the 304 W board power. Where only a sparse figure exists, the cell says so.
