Although what interests us from the outset is the performance and it should be noted that the company co-founded by Gordon Moore did not talk this time about performance improvements via the CPI, but rather focused on other areas of the processor with such power to boot. a 15% more single-threaded and 41% multi-threaded performance over previous generation. In a comparison, it is understood that it is model by model.
CPU efficiency improvements
If we want a processor better than another without increasing the IPC, we only have to increase the clock speed, this led to a maximum consumption going from 241 W to 253 WHowever, sticking with this part of the message is counterproductive. Since Intel managed to improve the curve between clock speed and voltage which allowed them to launch models at higher frequencies than in the previous generation and it is also expected a i9-13900 KS with the possibility of running at 6 GHz in Turbo.
Improved Thread Director
P-Cores and E-Cores have different performance, but when to use one or the other? Well, the Intel Core 13’s control unit is one of the most complex points, since it has the task of assigning which core the various software processes go to. The trick is to have a system that properly categorizes processes, which the operating system usually does. Well, Thread Director fulfills this function and above all, it learns over time to place them correctly in the corresponding core thanks to the Machine Learning functions that it integrates.
The wire director It’s one of the essential pieces for the asymmetric core philosophy to work and it will improve with each new generation of Intel Core. The objective is that the operating system is not in charge of distributing the work, but the processor itself, taking into account elements such as latency and energy cost of operations according to the resources available at a time given.
Important Changes in E-Cores
If we talk about the performance cores, the so-called P-Cores, the changes have been minimal, however, the E-Cores which have been designed to perform tasks in the background and release the former have received quite a significant improvement . First, we have that the amount has doubled in the higher end models. Second, they have been improved by increasing their L2 cache in the process and third, their Boost has been increased to 4.3 GHz.
Internal communication and DDR5 improvements
Intel uses a ring-shaped topology in its processors, this means that for each clock cycle, data is transmitted to the next segment. What’s good about that? This reduces the complexity of the pass-through, but as the cores and other connected elements increase, the latency increases and is counterproductive. Since the i9-13900 is made up of 8 P cores with 16 HyperThreading connections, then 16 E cores, this makes a total of 32 elements. A 33% increase over the previous generation which also comes with a greater amount of L3 cache, which now reaches 36 MB.
Think of the ring as a radial or circular highway where each CPU core is an output. What did Intel do? Well, in order to reduce latency, the speed at which it works has increased. It is a decision that is not easy, since it requires a redesign of the CPU from scratch so as not to explode energy consumption compared to the previous generation. What did they achieve? Go from a speed of 900 MHz to 5 GHz.
If we talk about memory already, we will find that the Intel Core 13 maintains the DDR4 memory controller in which there is no change from the previous generation, however, all the meat on the grill is in its improved support for DDR5. A type of memory that we recommend to use for those who want to buy a new PC. This time it supports DDR5-5600 memories without overclocking and therefore without added latency and up to DDR5-8800 memories with overclocking and therefore with added latency.
Intel Core 13 Gaming Performance
As usual, Intel has shown in comparative graphs the performance of its new processors compared to those of the previous generation and to the AMD Ryzen 5000. As a negative point, it should be noted that the comparison with the Ryzen 7000 does not has not been made, although This is understandable given the proximity in the launch of the two processors.
What are the available models of Intel Core 13?
The first Intel Core 13 models and their specifications are as follows:
Incidentally, we note that the KF models differ from the K in that they lack graphics integrated into the interior. Incidentally, we note that these are not the only microprocessors of this family that we will see in the months to come.
