AMD Radeon RX 6600S vs Intel Arc A380 vs Intel Arc A770

AMD Radeon RX 6600S

The AMD Radeon RX 6600S is a mobile mid-range graphics card based on the Navi 23 chip (RDNA 2  architecture) manufactured in the modern 7nm process. It features 1,792 cores (28 CUs - compute units) and 8 GB of fast GDDR6 graphics memory connected with a 128 Bit memory bus. The chip also includes 32 MB Infinity Cache. The RAdeon RX 6600S is the power saving variant of the RX 6600M with reduced core speed of 1.88 GHz versus 2.2 GHz. 

AMD compares the gaming performance to a low power RTX 3060 for laptops (80W, former known as Max-Q). When Raytracing effects are activated, it falls behind the GeForce GPUs.

The Navi 21 chip is manufactured at TSMC in the modern 7nm process. Thanks to the reduced TDP of up to 80W, the RX 6600S is well suited for thin gaming laptops.

Intel Arc A380

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.
