It seems that Intel has decided to put the batteries with the 10nm lithography, also thinking about important changes in the development of processors. The company needs to make major changes in the coming years to adapt to the new market demands. Now the performance of 10nm Ice Lake-SP processors has leaked, thanks to SiSoft Sandra, being a major beast.

Intel's main problem is the manufacturing problems of monolithic processors. The smaller the lithography, the more difficult it is to integrate all the parts of a processor successfully. But it seems that they are managing to solve these problems, showing the great leap between 14nm and 10nm, as reflected in the Intel Ice Lake-SP.

Intel Ice Lake-SP improves CPI by 54%

Thanks to SiSoft Sandra we know a 14-core, 28-thread Ice Lake-SP processor that uses 10nm lithography. When an Intel processor appears in SiSoft Sandra, it means that they are working on optimizing the working frequencies. Very interesting to see that this processor also has 21MB of L3 cache and 17.5MB of L2 cache. We can see that it works at a base frequency of 2.0GHz and the Boost mode is not specified.

Said Intel processor obtains in arithmetic tests a total of 360BOPs, in multimedia tasks it reaches 1.4Gpix / s and in cryptography up to 23GB / s. It offers a memory bandwidth @ 2666MHz of 98.1GB / s. It is very good data to have 14 cores @ 2.0GHz.

Let's compare it to the 6132-core Xeon Gold 14 @ 3.2GHz in a dual socket configuration. The two processors offer 750GOP, which if we divide it by the 28 cores and the frequency of 3.2GHz (750 / (28 * 3.2)) we get 8.4 points per core. Now we divide the 360GOP of the Ice Lake-SP between the 14 cores and the 2.0GHz (360 / (14 * 2.0)) and we get 12.9 points.

We can see that the improvement in the CPI is approximately more than 50%, which is very good. We are talking about an important performance jump with respect to the current 14nm. We will see if with this important jump Intel competes (with fewer cores) with the most beast processors from AMD.
