Intel Arc A770M vs AMD Radeon R9 M390 (Mac Edition)

The Intel Arc A770M is a mobile graphics card that launched in 2022. It is built on the Generation 12.7 GPU microarchitecture (codename DG2-512) and is manufactured on a 6 nm process.

Memory

The Arc A770M has 16 GB of GDDR6 memory, with a 2,000 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 512 Gb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.

Cores and Clock Speeds

The Arc A770M includes 4,096 shading units, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,650 MHz and can dynamically boost its clock speed up to 2,050 MHz. Complementing the processing units are 256 texture mapping units (TMUs) for efficient texture filtering and 128 render output units (ROPs) for pixel processing. Additionally, the GPU features 512 Xe Matrix Extensions (XMX) optimized for AI workloads and 32 ray tracing units dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 120 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The Arc A770M has the 48th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 35.73% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
