The Apple M2 Ultra SoC represents the company’s top model. With an impressive number of 134 billion transistors, it offers outstanding performance. The CPU consists of a total of 24 cores, which operate in a configuration of 16 (for maximum performance) and 8 (for optimal efficiency). In addition, the SoC has up to 76 GPU cores and a unified 192 GB memory with an impressive maximum bandwidth of 800 GB/s. Another notable innovation is the new Neural Engine with 32 cores. Apple promises a performance increase of 20% on the CPU side and even 30% on the GPU side.
Performance results have also been leaked, suggesting that the Apple M2 Ultra SoC offers impressive CPU performance. On the GPU side, there is also promising information, although no specific details about the number of cores or their architecture are available. The leaked performance benchmarks of the Apple M2 Ultra SoC have surfaced in both versions of Geekbench, Geekbench 6 and the older Geekbench 5. These benchmarks offer a glimpse into the performance of both the CPU and GPU, as some results have since been leaked. Let’s start with the CPU side, where the clock speeds of the Apple M2 Ultra SoC range from below 3 GHz to 3.7 GHz. However, it is difficult to determine exactly which cores are responsible for the performance and efficiency, as the benchmark does not differentiate cores by their architecture or state. Nevertheless, the leaked performance results suggest that the Apple M2 Ultra SoC offers quite impressive CPU performance. On the GPU side, there is no exact information about the number of cores or their architecture, but the leaked data also suggests promising GPU capabilities
The Apple M2 Ultra SoC for workstations scores up to 2809 points in the single-core test and 21,531 points in the multi-core test. In comparison, the Intel Core i9-13900KS achieves 3083 points and the AMD Ryzen 9 7950X 2875 points. In the multi-thread benchmarks, the mentioned chips score 21665 and 19342 points, respectively. It can be seen that the Apple M2 Ultra SoC is not faster than the mainstream Intel and AMD CPUs in terms of workstation performance.
Compared to the AMD Threadripper or Intel Xeon W chip, the M2 Ultra would be significantly inferior in multi-thread tests. However, Apple’s M2 Ultra has a clear advantage in single-thread tasks. The AMD and Intel processors are specifically designed for demanding multi-thread workloads, which is how they establish their dominance in the multi-core area.
In the compute benchmarks, performance comparisons were made between the NVIDIA RTX 4080 and AMD GPUs within the Metal API, which is primarily optimized for Apple SoCs. It is known that NVIDIA and AMD GPUs are not specifically optimized for Metal, as their market share on Apple OS is very small or even non-existent. An interesting finding is that the M2 Ultra SoC is 50% slower than the NVIDIA RTX 4080 in OpenCL, even though the latter is not even the top of the line GPUs.
The Apple M2 Ultra used in the popular OpenCL API just about matches the performance of the NVIDIA GeForce RTX 4060 Ti, a mainstream graphics card. However, it should also be noted that this is already the full 76-GPU configuration of the M2 Ultra that was compared. These benchmarks once again show that it is advisable to look critically at the numbers and performance claimed by Apple (and other companies) and use independent results to check whether the promised numbers are actually met. Only mainstream components were used in these benchmarks, and using workstation-oriented solutions would skew the results in favor of Intel, NVIDIA and AMD.
These companies offer more powerful CPU and GPU designs for professional and workstation applications. In addition, Apple’s Mac Pro offering with the M2 Ultra SoC is expected to have a base price of $7,000. And it’s worth noting that this price doesn’t even include the full specs of the SoC or the 192GB of RAM.
