Apple M1 Ultra - Geforce RTX 3090/64-core GPU

Nvidia's Geforce RTX 3090 is and will remain the world's fastest consumer graphics card, at least until the Geforce RTX 3090 Ti is released. Despite Apple's guarantees in the first tests, Apple's high-aspiration M1 Ultra CPU proved no match for the Ampere flagship in either gaming or compute tests.

According to Apple, the M1-Ultra will be based on a GPU with 64 cores and 8,192 execution units. 21 TFLOPS computing power should be obtained in single-precision applications.

The texture fill rate is estimated to be 660 GPixel/s, whereas the pixel fill rate is around 330 GPixel/s. With two video decoders, four video encoders, or four combination decoders and encoders, the M1-Ultra additionally supports hardware-accelerated H.264, HEVC, ProRes, and ProRes. In addition, there is 128 GB of shared memory.

However, in the excellent Shadow of the Tomb Raider gaming benchmark, the Geforce RTX 3090 was able to seize the lead with a comfortable lead of up to 32%. However, because games are not the M1 Ultra's core application, compute rates should be more significant. In comparison, the Mac Studio with M1-Ultra looks even worse.

The Geforce RTX 3090's Geekbench 5 score for OpenCL calculations is a decent 215,034 points. In comparison, the Mac Studio with M1-Ultra only gets 83,121 points and is outperformed by Nvidia's consumer card by a factor of 2.6.

It should be noted that the M1-Ultra is essentially double of the M1-Max and does not appear to scale performance appropriately in either computing or gaming testing. Instead of double the performance, with which the M1-Ultra of the Geforce RTX 3090 may still be dangerous, the M1-Ultra only achieves a 25-30% performance boost when compared to half the expansion stage.

This should also demonstrate how much faith Apple's own stats may be placed in. The official benchmarks appear to be characterized by excessive cherry-picking that has nothing to do with real-world applications, despite the fact that they are supposed to accurately represent the M1 Ultra.

This is primarily due to the fact that the Geforce RTX 3090 now usually costs less than $2,000, whereas the Mac Studio with 64 cores and 128 GB of memory costs at least $6,000.
