Benchmarks

Measured results, not specifications. Percentages are the gap to the leading product in each test.

Blender Cycles (GPU)

Blender 4.5, Blender Open Data (CC0). Median of monster + junkshop + classroom, combined samples/min.

Blender renders 3D scenes by tracing light through them, which loads every shader unit on the card at once. The score measures sustained render throughput, so it tells you what a card does in Cycles and similar renderers rather than what it does in a game. Figures come from Blender's Open Data project, which places no restriction on reuse, and we publish the median of every submission for that card on the same Blender version.

Verdict

Intel Acer Predator BiFrost OC Arc A770

7 / 10 Expert Rating

A solid mainstream pick if its price and 16GB VRAM allocation match your target resolution.

AMD Radeon RX 7800M

7.3 / 10 Expert Rating

A genuinely powerful mobile RDNA 3 GPU, competitive with high-end NVIDIA mobile parts, limited mainly by regional availability outside China.
