Arc B770 vs Radeon RX 9070 XT
cuda / stream coresを並べて確認。
cuda / stream coresを理解する
CUDA cores are NVIDIA's general-purpose shader units. They handle raster rendering, compute, and general parallel workloads.
Cross-generation comparison
CUDA cores from different architectures (Ampere vs Ada vs Blackwell) are not equivalent — Blackwell cores deliver more work per clock thanks to architectural improvements. Within the same generation, CUDA count is a strong predictor of performance.
Related units
- Tensor Cores — accelerate matrix math for DLSS, ML inference.
- RT Cores — accelerate ray traversal.
- CUDA Cores — everything else (raster, general compute).
A modern RTX card lists all three. Tensor and RT counts scale roughly with CUDA count within a generation.
この対戦In this spec, Arc B770 and Radeon RX 9070 XT are effectively tied at 4096 — buyers can treat them as equivalent on cuda / stream cores alone.
cuda coresとは？
NVIDIA's parallel shader processors. Each CUDA core executes one floating-point or integer operation per clock; total count is a rough indicator of raster throughput within a generation.
