Geforce RTX 3090 circles the 64-core GPU


from Maximilian Hohm
Nvidia’s Geforce RTX 3090 is and will remain the fastest consumer graphics card in the world, at least until the release of the Geforce RTX 3090 Ti. Despite Apple’s assurances in the first tests, Apple’s M1 Ultra chip with high aspirations was not a serious opponent for the Ampere flagship in either gaming or compute tests.

According to Apple, the M1-Ultra should be based on a GPU with 64 cores, which should provide 8,192 execution units. In single-precision applications, 21 TFLOPS computing power should be achieved. The texture fill rate is said to be 660 GPixel/s, while the pixel fill rate is around 330 GPixel/s. The M1-Ultra also supports hardware-accelerated H.264, HEVC, ProRes and ProRes with two video decoders, four video encoders or four combined decoders and encoders. There is also 128 GB of shared memory.

In the exemplary Shadow of the Tomb Raider gaming benchmark, however, the Geforce RTX 3090 was able to take the lead with a comfortable lead of up to 32%. However, since games are not the M1 Ultra’s primary area of ​​application anyway, the compute rates should be more important. Here the Mac Studio with M1-Ultra looks even worse in comparison. The Geekbench 5 score for OpenCL calculations for the Geforce RTX 3090 ends up at a respectable 215,034 points. In comparison, the Mac Studio with M1-Ultra only achieves 83,121 points and is beaten by a factor of 2.6 by Nvidia’s consumer card.

It should be noted that the M1-Ultra is more or less a doubled M1-Max and does not seem to scale performance properly in either the compute or gaming tests. Instead of twice the performance, with which the M1-Ultra of the Geforce RTX 3090 still could not become dangerous, the M1-Ultra only achieves a 25-30% increase in performance compared to half the expansion stage. This should also make it clear how much trust Apple’s own numbers can have. The official benchmarks seem to be characterized by excessive cherry picking that has nothing to do with real applications and are supposed to represent the M1 Ultra well. This is a very poor idea, especially given that the Geforce RTX 3090 now regularly costs less than €2,000 and the Mac Studio with 64 cores and 128 GB of memory costs at least €6,669.
