Apple M4 10-core GPU vs NVIDIA GeForce RTX 4050 Laptop GPU

Apple M4 10-core GPU

The 10-core Apple M4 GPU is a graphics adapter built into the 9-core and 10-core Apple M4 processors that has direct access to fast on-package LPDDR5x-7500 RAM (120 GB/s bandwidth) as well as hardware support for ray tracing and mesh shading and other modern technologies. It supports up to 3 displays with an "8K" resolution attainable on a single display. It also can HW-decode a few popular video codecs including first and foremost AVC, HEVC and AV1.

Performance

As our Fall 2024 Mac mini review confirmed, the iGPU is fast enough to run many 2023 and 2024 games at 1080p on low or medium quality settings. It appears its real-world performance is almost as good as the GeForce GTX 1650 Laptop. That being said, very few games have been compiled specifically for Apple silicon Macs meaning most titles have to be run via emulation layers. Some of them are displayed with visual artefacts as a result, or don't start at all.

M4-powered iPad Pros will be much slower in long-term GPU-intensive workloads than M4 iMacs, Mac minis and MacBook Pros due to the lack of proper cooling.

Power consumption

In M4 Mac minis, the GPU gets just slightly over a half of the total 40 W power budget allocated to the entire M4 chip. Needless to say, it has to be a lot more modest in iPad Pros where the entire M4 chip can consume ~14 W in short-term tasks and less than half of that in long-term tasks.

Just like the rest of the M4 chip, the graphics adapter is manufactured on a "second generation 3 nm" TSMC process which is still cutting-edge as of late 2024.

NVIDIA GeForce RTX 4050 Laptop GPU

The NVIDIA GeForce RTX 4050 Laptop GPU (codename GN21-X2) is a mid-range laptop GPU. It is based on the AD107 chip and uses the Ada Lovelace architecture. The RTX 4050 Laptop offers 2560 shaders and uses 6 GB GDDR6 dedicated graphics memory with a clock speed of 16 Gbps (effective) and a 96 Bit memory bus. The TGP (Total Graphics Power) can be configured between 35 and 115 Watt (+ 10-25 Watt Dynamic Boost from the CPU) leading to different performance levels. The boost clock depends on the TGP settings and ranges from 1605 MHz (35 Watt) to 2370 MHz (115 Watt). The performance therefore is also highly depending on the laptop and TDP settings.

In our benchmarks, the RTX 4050 stays slightly behind the older mobile RTX 3060 but is clearly faster than the mobile RTX 3050 Ti. Therefore, it is best suited for 1920x1080 gaming at high to ultra settings depending on the game (see benchmarks below).

The RTX 4050 offers 80 tensor cores and therefore supports DLSS 3 including frame generation that can have a big impact in supported games. The raytracing cores however will see less usage, as the RTX 4050 does not offer enough performance for high detail settings and raytracing in demanding games.

The AD107 chip is manufactured on 5nm at TSMC (4N process).
