Intel Arc A770 vs Intel Arc A770M vs Intel Arc B580

Intel Arc A770

The Intel Arc A770 is a mid-range desktop GPU and is manufactured using the 6 nm process at TSMC. The graphics processor has 4,096 shader units and 8 or 16 GB GDDR6 VRAM with a 256-bit interface (16 Gbps, 512 GB/s).

Features

As the top model based on the Alchemist architecture, Intel offers the Arc A770, the top model in the series. As a completely new development, Intel wants to put pressure on AMD and Nvidia with these graphics cards. Features such as ray tracing are supported and the Intel Arc A770 comes with 32 RT cores. Intel is also implementing 512 Tensor Cores, which we can already find in the current graphics cards from Nvidia. With support for AV1, the graphics card is particularly interesting for content creators. Only the Ada Lovelace models from Nvidia and the RDNA3 GPUs from AMD are currently capable of hardware-side encoding and decoding with the new codec.

Performance

The performance of the Intel Arc A770 is comparable with an Nvidia GeForce RTX 4060 or an AMD Radeon RX 7600 comparable. The Intel model copes much better with newer games. With ray tracing enabled, the Intel Arc A770 can even outperform its two competitors. Based on the performance shown, the Intel Arc A770 is ideally suited for 1080p gaming in 2023.

Power consumption

The manufacturer specifies the power consumption of the Intel Arc A770 at 225 watts (TGP). This is slightly more than a Nvidia GeForce RTX 4060 or the AMD Radeon RX 7600.

Intel Arc A770M

The Intel Arc A770M (Device ID 5690) is a dedicated mid-range graphics card from Intel for notebooks. It is based on the ACM-G10 chip and offers all 32 Xe cores (512 ALUs), 32 ray tracing units, 6 MB L1 cache and 16 MB L2 cache. The clock rates can range from 300 MHz to 1650 MHz (gaming) to 2050 MHz (turbo). The memory interface is 256 bits wide and supports 16 GB GDDR6 graphics memory with 16 Gbps. The TGP is between 120 and 150 watts depending on the model.

The performance of the A770M is on average of all games we tested approx. 4% ahead of a mobile RTX 3060 laptop GPU. However, there are significant deviations depending on the game. In Kingdom Come Deliverance 2, for example, the A770M can reach the level of an RTX 3070 laptop GPU and demonstrate its theoretical performance.

The ACM-G10 chip is manufactured at TSMC in 6 nm (N6 process), uses a BGA2660 interface (resolved), offers 21.7 billion transistors and is 406 mm² in size. It integrates two media engines for VP9, AVC, HEVC, AV1 8k60 12-bit HDR decoding and 8k 10-bit HDR encoding. The integrated 4 display pipes support 4x 4k120 HDR, HDMI 2.0B, DP 2.0 10G and Adaptive Sync.

Dynamic Power Share can be used with a 12th generation CPU (Alder Lake) via Deep Link.
