Apple M3 Pro 14-Core GPU vs AMD Radeon RX 7800 XT

Apple M3 Pro 14-Core GPU

The Apple M3 Pro 14-Core GPU is a self-designed graphics card in the Apple M3 Pro (with 11 CPU cores) and offers fourteen of the eighteen cores available on the chip. The graphics card uses a new architecture and now offers dynamic caching, mesh shading and ray tracing acceleration.

The GPU can access up to 24 GB LPDDR5-6400 unified memory via a 192-bit memory bus (max 150 GBit/s). Thanks to dynamic caching, the GPU only reserves as much memory as is required.

The entire chip is manufactured in the current 3nm process (probably N3B) at TSMC.

AMD Radeon RX 7800 XT

The AMD Radeon RX 7800 XT is a mid-range desktop GPU and is primarily designed for gaming in 1440p. This makes the AMD Radeon RX 7800 XT the fourth-fastest model of the current Radeon generation and places it directly behind the AMD Radeon RX 7900 GRE. The graphics chip is manufactured using the 5 nm process at TSMC. The chiplet design is also used in the AMD Radeon RX 7800 XT, although there are only four MCDs here. Nevertheless, the AMD Radeon RX 7800 XT has 16 GB of VRAM, beating the Nvidia GeForce RTX 4070 in terms of technical data.

Features

RDNA 3 continues to serve as the basis for the Navi 32 graphics chip. The already established features such as SAM (Smart Access Memory) and the Infinity Cache are also available in the new mid-range model aka Radeon RX 7800 XT. Compared to the AMD Radeon RX 6800 XT the ray tracing part has been revised and AI support has been implemented on the hardware side. The media engine has been updated and videos can be decoded/encoded with a resolution of up to 8K. The modern DisplayPort connection is also available on the AMD Radeon RX 7800 XT, as version 2.1 is currently only available from AMD. AMD's answer to DLSS is FSR 2.0 and offers a significant increase in performance in games with the upscaling option. With FSR 3, there will be another feature in the near future which, like DLSS 3.0, promises even better frame rates thanks to frame generation.

Performance

The performance of the AMD Radeon RX 7800 XT in games without ray tracing is well ahead of an Nvidia GeForce RTX 4070. The Nvidia GeForce RTX 4070 Ti is out of reach for the AMD Radeon RX 7800 XT. In the in-house duel, the performance of the AMD Radeon RX 7800 XT can be compared with an AMD Radeon RX 6900 XT can be compared.

Power consumption

The power consumption of the AMD Radeon RX 7800 XT is estimated by the manufacturer at 263 watts (TBP) and is therefore significantly more efficient than an AMD Radeon RX 6900 XT (300 watts). Compared to the Nvidia GeForce RTX 4070 the AMD Radeon RX 7800 XT requires 63 watts more. Also an AMD Radeon RX 7900 GRE is also more economical at 260 watts.
