CPU

PROCESSOR (CPU)

 

The processor or "CPU" is the heart and integral part of a computer without which no modern computer could function. It indicates the pace with its internal structure of the whole assembly and thus affects the overall performance of the PC in the maximum dose. The processor selection defines the PC as a whole.

There are a number of processors, but we will be interested in 3 basic platforms:

  • INTEL 
  • AMD 
  • ARM 

INTEL

It is the most widespread platform in the world, excelling primarily in price but also in performance. Intel established itself mainly from the beginning of the computer era when it was the only one able to supply an extreme number of XEON CPUs (lots of cores and lots of threads) for server needs, CENTRINO CPUs which were widely used in the time of the first long-life thin laptops office machines and even though players had a choice at the time, INTEL was always on top. The first big revolution in processors came with the first Core-i3 (dual-core) processor, then the Core-i5 (quad-core) and then the Core-i7 (eight-core) Intel switched to TurboBOOST 2.0 technology and added Hyperthreading, which until then was the domain of practically only data centers, servers and video editing reports). At that time, however, competition from AMD was catching up. So INTEL started to push the saw and today we have the core-i3 / i5 / i7 / i9 of the twelfth generation which still pays for the mainstream both in the work sphere and in the gaming world. In principle, it will always be cheaper than competing platforms.

INTEL is characterized by a cooler thermal profile, low consumption by wide and high frequencies and the possibilities of OVECLOCKING, which we will talk about below in the article as it goes across technology.

 

AMD

AMD has always been Intel's biggest competitor both in industrial use and in the gaming world at the time of Intel Centers. architecture, namely BULLDOZER, ie FX series processors. here one of the records youtuber known as "RX4D" got his FX-8320e over 10.2GHz. all four "Core Bulldozer". But such technology brings a problem and it's waste or waste heat and that's the real Achilles' heel of AMD. overcome. So, opposite Intel, you need massive coolers and good airflow. Furthermore the server solved EPYC which greatly surpassed Intel in numbers but the frequencies were extremely low and that kept it on the edge. AMD learned from everything they achieved and dealt a major blow to Intel when it gave birth to the RYZEN and THREDRIPPER processors, which today dominate the gaming world as many popular names are created due to their popularity and expansion, and AMD is trying to push down the price. Another benefit of AMD is the production of its own GPU (graphics cards) makes its HW much better set up for cooperation in the family circle of products from the very beginning, which today keeps it in the glory of the gaming world more than ever before. It should be noted that AMD is sometimes more expensive by tens of percent from the previously mentioned Intel, but for your money you will get unrivaled performance from AMD. 

AMD is characterized by extreme performance at a higher price, higher cooling requirements and more expensive components.

 

ARM

ARM processors are generally called SoC (or System on Chip) and are found everywhere in your phones, smart TVs, but also in refrigerators, for example. But what is important to us is their performance vs. consumption. everyone knows it .. You sit at home to your PC turn on PUBG and wow .. FPS fall almost under 25 and the game is not only impossible to play but not watchable and at the same time you pull the phone out of your pocket to join the fight and you are the winner and at the same time in both cases you have 1080P resolution what is it ?? It's a difference in architecture. about a combination of several factors unix operating system, higher efficiency FPS / watt, completely different architecture .. but why are we writing about it? Because everyone small and large wants to play and the manufacturers know it well. And so Qualcomm came up with a Snapdragon 8cx processor. here you can watch his fight with mainstream i5 from Intel https://www.digitaltrends.com/computing/snapdragon-8cx-vs-core-i5/ it's not a classic X86 / X64 platform like Intel and AMD, but inside it's a cleverly forged emulator X86 and thanks to that you can install a classic operating system instead of Unix and play and work just like on your PC with the difference that the consumption is 10x lower and the same performance .. Although it is one of the first swallows, but as a Unix lover (Arch Linux, Manjaro, OpenSuse) I'm incredibly looking forward to the first ARM dedicated gaming platform with the capabilities of a regular PC (not like PS or Xbox) I'm looking forward to this year's news, which we will inform you about in the weekly blog on our website. 

 

Now we will talk about how to properly choose the best processor for your needs and you will get an overview of performance measurement and thus the opportunity to more appropriately select the CPU for your set according to your work or gaming PC.

A very suitable and well-known program is "PassMark" and "PCMark" which performs the so-called "BENCHMARK" (PC assembly test for stability, performance and detection of possible problems). whether or not some components together form a HW / SW problem that can cause system instability. Every computer from us passes a very decent 4-hour test. Occupationally called "Baptism by Fire" where all components reach their maximum artificial level are left throughout the test. For such assemblies, we monitor the proper function of cooling, stability, FPS drops, and overall stability of assembly performance. we can find solutions only by updating and setting the bios, replacing components, or debugging software. We always communicate this with each customer individually and everyone will receive a test certificate with the test values and a successful burn test. Then all you have to do is unpack the PC and start working, playing, watching YT or starting streaming. You can get the programs here from the links listed below

And because you already know how it works, we will show 2 examples in practice. For both of me, I chose the same graphics card to distinguish them from Intel vs. Amd processors and you immediately notice the difference in performance.

PC INTEL

Apex Legend

1920 × 1080 (FullHD) - 138 FPS
 
2560 × 1440 (QuadHD) - 103 FPS
 
3840 × 2160 (4K) - 88 FPS

PC AMD

Apex Legend

1920 × 1080 (FullHD) - 168 FPS
 
2560 × 1440 (QuadHD) - 125 FPS
 
3840 × 2160 (4K) - 106 FPS

As you can see the same GPU (graphics card) and different CPU (processor) difference in frequencies -100MHz for AMD and yet Intel can solidly beat .. How is it ?? It's about efficiency. what Intel drives with AMD frequencies can compensate for SMT technology (super multi treding) Which increases its efficiency even at lower frequencies and sometimes even 15-25% is of course more expensive but the performance is indisputable. This is just one example of a player in the case of applications that use nothing but the first 2 cores and no threads, so Intel will dominate by 5-7% percent but will. so again the important question is what the PC will be used for. The more we know your requirements, the more we will find the most suitable machine for you.  

So at this point we have a rough idea of what is the most suitable option for us according to our needs. But what if you want to share your gaming experience with the world? How to do it? what do we need for that? and how will it affect us in this CPU? we will explain it here.

So .. What CPU to stream? This is a tricky question. So let's explain the basics first, as this possibility depends on several factors. First of all we will take the reference “PC AMD” with Ryzen 5. We will stream APEX LEGEND in 4K and we know that under such conditions it will give us beautiful 106FPS of course that if we start streaming we will take a lot of CPU power and GPU as well .. cases up to 30% Processing of all events + audio processing and all under a profile to send the network to the world simply bites a piece of performance .. So we can afford to stream from 4K but only 60FPS to make the gaming experience stable for both players and watchers on platforms . In the case of the reference "PC INTEL" with Core I-7 in 4K we have only 88 FPS. Thus, with the 30% power cut we cannot expect smooth 60FPS, so it will be necessary to settle for only 2K (1440p) at 60FPS. is 100MHz weaker than Intel .. So you can say that the stream in 4K 60FPS needs a CPU that has 22182 points or better.              rating

                                                                                         22182 points

Generally speaking, streaming between 1080p and 4K needs performance equal to that of Core i5 4generation, ie 4 cores 4 fibers about over 3GHz, such a processor has 5392 points. This power is necessary for the streaming itself without the PC doing anything more.

Therefore, deciding which CPU to use is extremely important. And that's why every assembly should start with the choice of CPU. We always do that and thanks to us you know it now.  

Thermal Profile (TDP)

As I presented another factor influencing the selection is the thermal profile .. for a computer for gaming, video editing and streaming it is necessary to take into account good cooling and therefore noisier traffic which is limited by a few factors that we will talk about. Quiet operation and low temperatures, therefore, even more compact packaging can be expected for office and multimedia PCs. Furthermore, this parameter also affects the compactness of the design because the 16cm cooler simply does not fit in the MiniITX.

For game sets, great care must be taken to ensure proper CPU cooling, regardless of the type (although we all know that AMD is a high-temperature champion, even for GPUs). So let's talk about the TDP alias Thermal Design Power. So we are talking about the maximum heat loss of the processor, which is the ratio between voltage and current that the processor can withstand in the worst conditions .. ie its healthy maximum at which the manufacturer guarantees functionality during the warranty period. 

Each processor has this value elsewhere. High TDP does not always mean high performance because we have to look at it with respect to generations of CPUs where each subsequent generation has a higher frequency, higher power, lower or the same power consumption. Consumption is given in Watt .. For example Core-i5 4670K, TDP-84Watt.

Thus, in the case of AMD, we must more generally count on a larger heatsink, ie the maximum MicroATX case in the classic air cooler, since the TDP in the AMD is on average 75-125W. On the other hand, INTEL heatsinks in "similar" power (benchmark points) can also use MiniITX as its average TDP is about 65-84W. The wrong choice of cooling results in a rapid destruction of the processor, or a slower variant where lags, shutters and eventually an extreme drop in performance gradually appear. In the best case, you will not "only" reach the nominal power. 

However, air cooling, thermal pastes and water cooling will be our own chapter, which we will talk about in another article, where we will analyze it to the point…

We learned other concepts, understood more deeply the compactness of CPU selection and now let's look at something that interests every player and that is…

OVERCLOCKING (OC)

Asai's most interesting, mysterious, and most prized ability was to be able to squeeze more FPS out of the CPU without burning it. today has the button OC or PERFORMANCE mod .. So you can solve everything with one click without fear and without BSOD (blue death) For Deep OC you still need to know a lot of parameters and their interaction. The basis is the multiplier, CPU voltage, frequency cores and bus speed. Thanks to this, even a less experienced user can safely achieve up to 10-15% power increase without having to work on cooling or something source. Lately he's been hit by TICKETING. paradoxically by reducing the voltage and maintaining the frequency, the current and thus the temperature will drop, which will allow higher performance and lower FPS drops and increase fluidity as the processor can practically never throttle again or reach the maximum TDP and in "self-defense" CPU will automatically reduce the frequency which results in an enormous drop in performance.
