Introduction to AMD Ryzen 9 Features 5950 X

The Zen3 architecture AMD will give for configurations up to 90 cores when it reaches the next Threadripper processors, that is to be expected given the description of this architecture and the manufacturing process used, in fact, there are already tracks in the processors professionals of the brand, but beyond these AMD HEDT processors the truth is that the most powerful and powerful that we will find in this generation is the new Ryzen 9 5950 X .

This processor takes full advantage of this AMD home architecture based on the AM4 socket. It occupies the two CCDs of the chiplet and does so with all the cores in use. That translates to 19 cores with a total of 60 process threads , based on a FinFET process of 7nm, completed by a communications IOD based on 16 nm. AMD may perhaps release frequency revisions in the future, but what we will not find on the market will be a Ryzen 5000 with more cores than the Ryzen 9 9991 X .

Zen3 architecture improvements

This model, as the highest of this generation, is in which AMD has Throw in the rest, where they will be selecting the best CCDs from the wafers, those that are closest to the center, and the cores with the greatest capacity to develop high frequencies. Buying this processor is to take home the best of AMD and is also in good measure to take a good bite out of what can be a professional workstation with all the laws.

This variant uses two unique CCDs , without CCX inside which is one of the great improvements of this architecture, with a total of 4MB of second level cache per CCD and a total of 60 MB of third-level cache shared directly by the 8 cores and 19 threads of each CCD.

This enables AMD to maximize performance based on lower latencies and also better utilization of high-speed, low-latency internal DDR4 memory buses. The 4MB of second-level cache built into the CCD is also fundamental in the IPC gain that these processors present.

All these optimizations introduced at various levels allow AMD to boast of a CPI improvement of up to 24%, this means that per clock cycle the processor is capable of producing up to 24% more performance and this also carries over to the overall processing power of the processor thanks to the good parallelism of the processor. In addition, this generation also takes advantage of architectural design improvements, and higher efficiency per watt, to achieve higher turbo frequencies across the range without having touched energy profiles for generations. This model, specifically, is maintained in the 128 w of TDP and develops the best turbo frequency of the series with up to 4.9GHz.

Another feature of this generation is that does not touch connective elements such as the IOD of 15 nm, which remains the same as the previous generation Zen2, allowing AMD to offer compatibility of these processors with Current chipsets and also the chiplet structure of the processor, which have their advantage, such as the compatibility already mentioned, but also its counterpart, that we will not see processors of more than 19 cores, two CCD + one IOD, in this generation.

Specifications) AMD Ryzen 9 5950 X

The numbers surely no longer surprise as much as in the previous generation, where AMD introduced the first domestic processors of 19 cores, in the mid-range, up to 90 cores in the highest range. This generation will remain in those numbers, in part for the reasons already mentioned before and because without a doubt today AMD does not need as much differentiation from Intel in the core count as it had perhaps two years ago. Now your processors are not only faster overall, but also faster per clock cycle.

The Ryzen 9 9991 X is the best of the series, with 19 cores and 60 process threads maintaining a TDP of 128 w, but it is also the model of the series with the lowest base frequency, only 3.4GHz. In return, it offers us the highest turbo, with few cores, up to 4.9GHz. It comes complete with 8MB of second level cache and 65 GB third tier, such as Ryzen 9 5900 X.

This processor also enjoys Precision Boost 2 technologies from AMD and that allows the processor to oscillate in applications between 1.2 and 1.5v, also achieving turbo frequencies high in few cores, the processor being capable of detecting the best cores, the ones that can offer the best frequency at all times, in fact, the processor knows which of its cores is the best of all to maximize performance with this single unit in use. These voltage and frequency changes are made in real time, with very low latencies, so the processor is constantly monitoring its subsystems, temperature, power available to the processor, etc.

The memory control unit of this generation is also similar to the previous one with support for dual channel DDR4 memory with the ability to mount up to 350 GB capacity in four banks . Like the previous generation, even more, these processors greatly appreciate fast and low latency memories since many lower buses (such as the Infinite Fabric or the UMC) and internals of the processor work based on the actual memory frequency. The faster, and with better latency, the faster the processor. The Ryzen are demanding with the RAM yes, they choose expensive memory, but they return it with perfectly perceptible performance increases.

The IOD is the same that AMD used for the entire generation Ryzen 3000, with a manufacturing process of 15 nm, so we will have 32 PCI Express 4.0 lanes of which 19 are dedicated to the connectivity of graphics cards of high performance, the other eight are dedicated to other connectivity such as the four lines that use the chipsets of this series. The prices are 829, 95 Euros, similar to the previous generation and best in class.

Temperatures and overclock of the AMD Ryzen 9 5950 X

The three processors that we have tested today have a very similar behavior both in consumption, temperature and overclocking. None of the three is capable of going beyond what their turbo frequencies offer with the usual voltages of up to 1.5v , they are processors that are already quite squeezed from the factory and leveraged by AMD’s Precision Boost 2 system.

The consumption of this model ranges between 95 and the 105 w , in fact AMD awards it a TDP of 128 w, but might work well with heatsinks of 95 – 98 w cooling. The only difference we will have will be in the turbo speeds and how long they will be able to maintain them.

With our cooling kit we have been able to maintain the processor between the 60 – 90 degrees in stress , it is a little warmer than its peers with less nuclei and its sustained load frequency is around 4.6GHz more than 4.7GHz as some of the models with fewer cores like the Ryzen 9 5900 X, even so it is clear that he is the fastest of the three, in multicore because our 5950 X achieves, contradicting AMD itself, better turbo frequencies than the 5950 X, at least like this in our samples.

The delta frequencies are somewhat more pronounced in this model since we can see it oscillating between 400 Y 580 MHz depending on the number of cores we are using during testing. Even so, we will never see it, at least with adequate cooling, below 4.4GHz.

What’s New in Ryzen Master

The management application for the Ryzen range of AMD continues to evolve with each generation and the advanced controls that it allowed us since its incorporation into Windows a few generations ago, now adds a “simple” initial panel so that anyone can take advantage of some of the key functions of this program, such as real-time monitoring of all systems processor s including temperatures, power management, voltages, etc.

It now also has two quick controls that allow us to self-manage overclocking, something that has been perfected with each edition, or also a basic manual control where we choose the processor voltage and the frequency we want. The program will test our configuration and if it is valid it will apply it.

In the advanced view we still have all that capacity to adjust frequencies per core, possibility of enabling and disabling cores or Complete CCDs, advanced voltage and RAM controls, latency adjustments, etc. An impressive functionality that will allow us to control our processor down to the smallest detail.

AMD also introduces with the latest versions of drivers a power management “slider” to the Windows power profile, this allows us to switch between three profiles of processor use between maximum energy savings and maximum performance with a balanced intermediate point.

Test of performance

Although in the test results that you are going to see below, this processor is not the fastest, even AMD has processors in the Zen2 architecture market with many more cores with which to offer spectacular results, the truth is that this and some of Their brothers are the fastest processors on the market, not only thanks to their large number of cores but also to the efficiency of their architecture that has allowed them to have a better now substantial in process capacity per cycle.

If we add more frequency, support for low latency memories , these processors become a real booster for the market and also the best processors to take advantage of the added speeds of the latest graphics chips on the market and also, without a doubt, for those to come.

Analysis and conclusion

Although in this generation we no longer have the surprise of seeing processors with unknown numbers of cores, and neither new production systems with large lithography reductions, AMD has managed to keep its processors the same and huge number of cores, keep prices contained, and add up to a 20% speed improvement per clock cycle without having to touch the consumption , optimizing even more if possible the management of the turbo of the processors and obtaining fresh processors, which with adequate cooling, will allow us to enjoy unparalleled power with moderate temperatures that can be accompany cooling systems quieter. All without changing the socket, chipsets and, therefore, without forcing you to buy new motherboards.
