the most powerful chip in the family stands out with 20 CPU cores and 64 GPU cores

  • 10

Apple has just released a new microprocessor from the M1 family. And, according to those from Cupertino, it is the most powerful of all. His figures promise. A lot. And it is that it incorporates 20 CPU cores, 64 cores for graphics, and has a power of 21 TFLOPS. However, these figures only tell us part of the story.

During the presentation of this chip, the spokespersons of this company have assured that the increase in the power of this microprocessor does not affect its efficiency in the least. It makes sense if we keep in mind that its microarchitecture is the same used by the other processors in this family.

Also, the other M1 chips have shown us in our tests that its efficiency is very competitiveso it is reasonable that this new hypervitaminized version of this CPU keeps this feature intact (something that we will check as soon as the first computer equipped with this chip falls into our hands).

More power than ever, but the same efficiency as always (according to Apple)

One of the first slides used by the spokespersons of this brand to publicize the new M1 Ultra chip clearly reflected that this processor double the surface of the M1 Max. Far from being anecdotal, this data invites us to intuit that the number of transistors integrated by Apple in the M1 Ultra processor is significantly higher (they are manufacturing it using 5nm photolithography and it incorporates 114 billion transistors).

16 of the 20 general-purpose cores built into the CPU are high-performance, while the remaining 4 cores prioritize efficiencyso they will be responsible for processing those execution threads (threads) that are not critical from a performance point of view.

The high-performance cores are supported by a 192 KB instruction cache, a 128 KB data cache, and share a 48 MB level 2 cache. On the other hand, the high-efficiency cores have at their disposal a 128 KB instruction cache, a 64 KB data cache, and lastly, they share an 8 MB level 2 cache.

These numbers on paper they look really goodalthough until we test a team with the M1 Ultra chip we will not know for sure how far it outperforms the M1 Max processor.

Let’s go now with the graphical logic. In the next slide we can see that the M1 Ultra chip incorporates 64 cores dedicated to graphics processing. Here are some figures that aim to illustrate the performance that this logic promises us: it incorporates 8192 execution unitsit can concurrently process no less than 196,608 execution threads, has a computing power of 21 TFLOPS, a texture fill rate of 660 Gtexels/s, and, to conclude, a pixel rate of 330 Gpixels/s .

It will be very interesting to see how this graphical logic performs in a real use scenario, but there is no doubt that it shows promise. A lot

These figures are absolutely spectacular. In fact, they rival without the slightest complex with those offered by graphics processors for desktop computers most powerful currently available. It will be very interesting to see how this graphical logic performs in a real use scenario, but there is no doubt that it shows promise. A lot.

One of the qualities that users appreciate most about the M1 family processors is its great performance / watt ratio. And, according to Apple, the new M1 Ultra chip keeps the pedigree of the other CPUs in this family intact. The next slide aims to put the performance and consumption of the M1 Ultra processor into context by comparing its figures with those of a PC equipped with an Intel Core i9-12900K processor and DDR5 memory.

There is no shortage of chips, there is a huge deficit: we are manufacturing more than ever and it is still not enough

It is clear that Apple is an interested party, and we do not know in detail under what conditions and with what software this graph was made, but there is no doubt that these figures contribute to set very high expectations around the M1 Ultra chip. It may not take long for us to confirm if these numbers accurately reflect reality, but, again, they are very promising.

Apple has raised expectations around the M1 Ultra processor

The characteristics that we have just investigated are not the only ones that this brand has released to describe the potential of the M1 Ultra chip. Apple has also revealed that the bus that acts as a communication interface between the different functional units of this microprocessor is capable of reaching a transfer speed of 2.5TB/san extraordinarily competitive figure if we compare it with those offered by other current CPUs.

The logic that is responsible for executing the artificial intelligence algorithms (which has 32 cores) is capable of carrying out 22 billion operations per second

More interesting facts. The maximum bandwidth of the memory bus amounts to 800 GB/s, and the logic that is responsible for executing the artificial intelligence algorithms (which has 32 cores) is capable of carrying out 22 trillion operations per second (they are billions of us, not of the Anglo-Saxons). Lastly, the M1 Ultra processor can address a maximum of 128 GB of main memory.

The figures that Apple has released today to ‘sell us’ its most powerful microprocessor are impressive. It is wisest not to get carried away with enthusiasm until we have the opportunity to test the first machine with this chip, but both the overall performance and the performance/watt ratio of the other processors in the M1 family invite us to anticipate that , effectively, the M1 Ultra chip should be a very competitive CPU. Let’s cross our fingers and hope we can find out very soon.
