Apple M3 8-Core GPU vs NVIDIA GeForce RTX 3050 vs Apple M3 10-Core GPU

Apple M3 8-Core GPU

The Apple M3 GPU is an integrated graphics card offering 10 cores designed by Apple and integrated in the Apple M3 SoC. It uses the unified memory architecture of the M3 SoC (up to 24 GB LPDDR5-6400 with 100 GB/s bandwidth). The GPU uses a new architecture with support for mesh shading and ray tracing. Dynamic caching is also a new feature that should only us as much shared memory as needed.

The old M2 SoC showed a difference of around 15% between the 8-core and 10-core variant. Therefore, we expect a similar difference for the M3 models. This means, the M3 8-core version should be slightly faster than the 10-core GPU in the Apple M2.

The M3 chip is manufactured in the new 3nm process at TSMC (most likely N3B). The power limit should be around the same 15 Watt as the 10-core variant.

NVIDIA GeForce RTX 3050

The Nvidia GeForce RTX 3050 is a mid-range desktop graphics card. It is based on the GA106 Ampere chip and offers 8 GB GDDR6 graphics memory with a 128 Bit memory bus. It offers 2,560 cores and supports PCIe 4.0.

The performance is similar to the older GeForce RTX 2060 and therefore best suited for 1080p gaming of modern and demanding games in high settings.

The GA106 chip offers 3,840 FP32 ALUs of which half can also execute INT32 instructions (i.e. 1,920 INT32 ALUs). With Turing all shaders could still execute FP32 or INT32 instructions. The raytracing and tensor cores on the chip were also improved according to Nvidia. The Ampere chips also include an improved 5th generation video encoder (NVENC for H.264 and H.265) and a 7th generation decoder (for various formats now including AV1).

The GA106 chip is manufactured by Samsung in 8nm (8N), which is not quite able to keep up with the 7nm node at TSMC (e.g. used by AMD and also for the professional GA100 Ampere chip). The TDP of the RTX 3050 is specified at 130 Watt and therefore better than the previous RTX 2060 (160 Watt).

Apple M3 10-Core GPU

The 10-core Apple M3 GPU is an integrated graphics adapter designed by Apple that features 10 cores. This iGPU is built into the Apple M3 SoC and it uses the unified memory architecture (up to 24 GB LPDDR5-6400 with 100 GB/s bandwidth). Compared to M2 series GPUs, this new graphics adapter uses a new architecture with support for mesh shading and ray tracing. Dynamic caching is another new feature worth mentioning - it is coming to optimize shared memory usage.

In our testing, the M3 GPU (10 cores) mostly was 5% to 20% faster than the 10-core M2 GPU depending on the task.

Just like the rest of the Apple M3 chip, the graphics adapter is manufactured on a 3 nm TSMC process (possibly N3B). Our MBP 14 review revealed sustained power consumption figures of around 15 W for the iGPU.
