The end of summer and the beginning of autumn is a time when big players in the IT industry present their novelties. AMD, in the US State of Texas, exactly where Peca was at the promotion of the Ryzen 5000 Renoir series processor for the laptop platform two and a half years ago, introduced the AMD Ryzen 7000 series. Practically the same place, but the reason is slightly different – this time a desktop central processor based on Zen 4 cores, Ryzen 7000 series under the code name Raphael. It is the successor to the very successful Ryzen 5000 series, which is definitely expected to repeat the success of the famous predecessor.
There is some symbolism, as the favorite saying goes - “Everything is bigger in Texas” because keep in mind that the state of Texas is twice the size of Germany. In keeping with this, AMD wanted to make an obvious reference to its new Ryzen processor and how much better it actually is than anything seen so far.
AMD Zen 4-the most important features
What can we expect from the new Ryzen 7000 series? First of all it is the new Zen 4 processor core architecture, then the transition to the 5nm production process, the new AM5 processor tray, the adoption of PCIe 5.0 specifications and finally the transition to a faster DDR5 memory standard.
First things first. Zen4 architecture provides an average of 13% better IPC, i.e. the number of instructions executed per cycle compared to Zen3 generation. This is actually the average that AMD has reached, but don't take this figure as a landmark of expected performance improvement because you'll see later in the analysis of test results that performance is significantly better than the previous one in most applications.
The maximum frequency of the single core has increased to 5.7 GHz, which is a big jump compared to the previous generation that struggled to cross the 5 GHz limit, so some 600-800 MHz more which is a serious jump for one generation of processors. AMD seemed to reject the manners of a cultured, calm guy and said – Wait, if Intel does that with its two generations of Core processors, we'll show what Ryzen can do and give it a full throttle. The result is impressive to say the least because the CPU frequency in the case of the strongest Ryzen 9 7950X model when all 16 cores are loaded to the maximum is 5.1-5.2 GHz. As far as this is actually a good result, we remind you of the fact that the R9 5950X predecessor in the same situations kept the limits of 3850-3950mhz.
How did he do that? First, a great credit is given to the transition to a more modern 5 nm making of transistors with the help of 4. TSMC FinFet technology, transistors have become smaller, faster and definitely more economical, this is followed by another important factor because AMD has introduced a new power limit - TDP 170 W. It set the ultimate limit of the temperature safety value to the same value as the predecessor 95 degrees Celsius, but the control algorithm pushes the processor much more aggressively towards that limit. In fact, I can say – this temperature limit is now the main landmark of the Ryzen 7000 series of processors. When loaded, it works in an interval of 70-95 degrees depending on the application being executed and its ability to employ all the core. There is no doubt that you will need the absolute best cooling there is to get the highest frequency average and the best out of your Ryzen Zen 4 models. This was the case during the tests whether it was the flagship 16-core Ryzen 9 7950X or the fastest mainstream eight-core Ryzen 7 7700x.
AMD Zen 4-key improvements at the architecture level
At the same time, the main generator of better performance in addition to undoubtedly higher operating frequency is the optimization of the architecture. All the best of the Zen 3 predecessors was kept and at the same time significantly improved the work of the “front end” part that is the part of the processor in which the instructions are downloaded from memory and prepared, decoded for execution. Another significant improvement at the architecture level concerns the Load / Store management of instructions between processor and memory. And finally branch prediction, which is the simplest technique used in CPU design that tries to guess the outcome of the operation and prepare for the most likely result. It is very important when it comes to x86 processors because the faster the processor is in question and the more the processor uses parallelism at the instruction level, the more important the flow of instruction control is for performance, and the more expensive the penalties are paid. So, these three techniques alone carry the bulk of the nearly 80% performance improvement of the new Ryzen Zen 4 processor, while the impact of execution units and second-instance cache is only 20%.
In addition, it received AVX 512 optimization for vector instructions that speeds up the operations of floating point numbers as well as 8-bit integers and especially the execution of artificial intelligence algorithms, all resulting in 29% better single core performance compared to the previous Ryzen 5000 series.
Also interesting is the fact that the new Ryzen uses half as much silicon material to build the core as Intel Core competitors.
It proves its energy efficiency i.e. energy efficiency in consumption by the fact that when delivering the same level of performance, it consumes 62% less energy than the previous models Ryzen 5000 Series, i.e. at the same level of consumption it delivers 49% better performance than its predecessor.
And here we come to another important point. You can say that because of the aggressively set parameters of work on TDP 170W parameters you do not have a good enough cooler to cool this Beast or you simply can not know in advance to what extent a particular cooler or cooling system is effective in cooling Ryzen 7000 processors and ultimately what price limit is cost-effective in investing efficient cooling.
AMD Ryzen 7000-ECO Mode
Eco Mode enters the scene, which allows the user to set the processor to a lower TDP value, i.e. consumption limit, and thus significantly affects the behavior in the work. Then the processor actually shows how efficient it is in terms of energy utilization. You have three consumption limits TDP=65W, TDP=105W and TDP=170w. energy savings can also be significant in that sense impact on heating. ECO mode is set in BIOS and for now is not a classic option that you choose with one click of the mouse. This will happen in some future BIOS update, and you find it in the motherboard option where you manually adjust the Precision Boost Overdrive parameters. Not to mention, here I give you parameters that you can experiment with and easily name them by creating the appropriate BIOS profiles.
And the impact is pretty big whether it's games or modeling and rendering applications.
In processor-intensive applications such as Cinema 4D renderer, where practically with the same level of consumption as the previous generation of some 134w achieves twice the result of one R7 5800x3d, with operating temperature of only 45 degrees Celsius.
Besides, the best way to figure it out is to look at the charts.
ECO Mode impact in application conditions:
ECO Mode impact on gaming:
In the example Borderlands 3 IgE, which is one of the most demanding processors, you can achieve practically identical performance on TDP 65W with 10 degrees lower temperature because the processor then with several engaged cores does an equally good job and allows the graphic map to perform its work area with lower electricity consumption and heating.
Thus, Ryzen 7000 gives you absolute freedom to adjust its performance characteristics and adapt them to the rest of the system primarily cooling system, thus achieving the best performance in terms of consumption, heating and speed.
AMD Ryzen 7000-Raphael brings RDNA 2 iGPU
The strongest copy of the Ryzen 7000 series still uses two CCD core Die Silicon chiplets made in 5 nm with a maximum of 8 cores each and one IoD in 6 nm practical system controller containing an integrated Radeon RDNA 2 graphics core. Yes, this is the first time a high-end AMD processor has integrated graphics, then controls HDMI 2.1 and Display Port 2.0 connections, and provides support for three second-generation USB 3.2 high-speed ports. All listed even more than that because now the audio codec is directly connected to the system controller within the CPU chip, just like the Super I/O controller.
On the other hand, AMD has learned a good lesson from the previous AM4 platform and chipset solutions. You remember that complex monolithic solutions used a lot of energy and heated so much that at first they required active cooling on the chipset fridge. This time, AMD does not repeat the mistake and is actually guided by the positive experiences of applying “chiplet” topology, so the X670 Extreme actually has two chipsets under the refrigerator. The chipset is partly connected by a 4x PCIe line 4 wide bus. generations.
See the AMD X670E chipset topology for more technical details.
As for the graphics core, it provides only basic support for the Windows desktop environment, or as you would say, is suitable for working in Office applications and allows you to watch movies since it has hardware decoding for H. 264, H265 and AV1 formats. To play, it is not.
AMD Ryzen 7000-new generation of AM5 motherboards
The new processors require a new slot, which in the case of AMD Raphael processors bears the designation AM5. After a long period of time, AM4 is deservedly retiring.
It is an LGA 1718 footer that supports processors with a consumption of as much as 230-240W in a situation of full resource engagement. So Ryzen processors run out of needles or legs. The tray is no longer a PGA i.e. Pin Grid Array, but as with Intel Land Grid Array i.e. LGA. The boards with the new base, have DDR5 memory support, as well as a PCIe 5.0 deployment that will be slowly put into operation until 2025. years. The first wave of SSD drives is expected in November this year. The good thing is that on the new panels you will be able to use the existing coolers with the AM4 system, which is certainly a very nice detail if you have already invested in a better cooling system.
As for the motherboards, the AMD X670 and X670 Extreme models will start at the beginning, which will differ in the number and type of supported connections and equipment in terms of the design of the VRM unit and cooler, while the more affordable ones in the form of the B650 and B650 Extreme models will appear in October. The price of the new generation of AMD boards starts at dolara 125 and up.
With these boards, the exclusive feature is the arrival of AMD EXPO profile technology for overclocking memory and RAM module performance, with a single click with 11% better performance in Full HD gaming. Currently, there are 15 sets of the most famous memory manufacturers that will enable you to achieve the DDR5-6400 level of performance.
According to JEDEC standards Ryzen 7000 series works with DDR5-5200 modules while using EXPO certified modules in overclocking mode, some sweet spot DDR5-6000 such as on AM4 DDR4 platform it was with DDR4 3600 modules.
As for the memory setting and synchronization of the RAM module, memory controller and factory bus operation, from now on you no longer adjust the latter because its operation is practically locked at 2000MHz, so from now on you only have 1:1 synchronization of the DDR5 module and the memory controller e.g. in the case of DDR5-6000 memory is 3000MHz in synchronous mode.

Applications
Kada govorimo o rezultatim izmerenim u aplikacijama za kreiranje zahtevnog sadržaja, Ryzen serije 7000 je više nego ubedljiv prilikom poređenja sa Vermeer prethodnikom. Razlika ideo od 7% pa do skoro 70% u korist Raphael modela što je u rangu prosekao od 30-ak % kao što je AMD i obećao. Ništa bolje nije prošao ni Intel Core i9 12900K sa zaostatkom od 20-ak posto, sa ekstremima kada su u pitanju Blender gde je razlika čak 150% brži ili Cinema 4D renderingu gde je 84% brži od trenutno najjače Intel Core i9 konkurencije.
Gejming performanse
Gaming performances have also improved, but they are not nearly as big a difference as in the case of apps. It is definitely faster than the Ryzen 5000 in more processor-demanding games such as FarCry 5 and a 10% difference or CS: GO with 17%, the biggest difference going up to 39% in some newer and better optimized games such as FarCry 6.
AMD Ryzen 7000-available models
Ryzen 7000 series processors start with several models. The strongest Ryzen 9 7950X will have 16 physical cores with the ability to execute up to 32 instruction sequences simultaneously with a core frequency that starts at 4.5 GHz and reaches a maximum value in the form of individual 5.7 GHz. The next is the 12-core Ryzen 9 7900X that works in the range of 4.7 – 5.6 GHz and consumption, like the predecessor of 170w. the next is the classic 8-core with the designation Ryzen 7 7700X with 16 “threads” and a frequency range of 4.5-5.4 GHz and consumption of 105W. finally, for many the most interesting six – core Ryzen 5 7600X has a 6C/12T configuration, it consumes 105W in the frequency range of 4.7 – 5.3 GHz.
Two words about prices. The fastest Ryzen 9 7950X comes with a real price of 900€ in our retail stores. The second Ryzen 9 7900X with 12 cores will be offered at a price of€ 700, while the classic “V8” Ryzen 7 7700x model will cost€500. In the end, for Ryzen 5 7600X you will have to spend 400€.
In the end, it should be mentioned that over time, in addition to the classic line of Zen4 models in AMD's offer, there will be a Zen 4 V-Cache variant with more cache, but also Zen 4C mostly server models of processors with 128 cores, which will be produced by even more advanced 4nm technology.
AMD Ryzen 7000-conclusion
And that's enough for today. There was even too much technical information I do not want to “burn” you with data because there will definitely be a lot of interesting data and tests in the time ahead of us. From this point on, AMD Ryzen Raphael and the X670 platform begin to evolve and receive improvements virtually every day.
Ryzen 7000 is no doubt the best processor for desktop PC today and we have absolutely no doubt about it. Whether it deserves an "Editor's Choice" or a recommendation, This is clearly understood from everything previously said and presented.
