Ruilong 9 7900X in-depth evaluation： the second flagship reached the top, and the game rolled up Intel.
Simple evaluation conclusion:
－ The comprehensive performance of CPU, although Ruilong 9 7900X is only the second flagship of AMD 7000 series, its performance has been stabilized at i9-12900K, leading by 8% in comprehensive evaluation, and it can lead by 28% compared with its previous generation product Ruilong 9 5900X.On the premise that the number of cores remains unchanged, the increase is quite amazing.
－ With the unique 3D performance, AMD has made remarkable progress this time, with an overall improvement of 2.5% compared with i9-12900K and 7% compared with the previous generation Ruilong 9 5900X.This is a real improvement brought by CPU, or a considerable progress, which also means that AMD’s 7000 series CPU is currently ahead of Intel in game performance.
-Comprehensive power consumption (the whole machine), although the full-load power consumption of the CPU of Ruilong 9 7900X is not high, about 180W, but the game power consumption is large, which leads toUnder comprehensive evaluation, the power consumption level of Ruilong 9 7900X will be close to i9-12900K.
-In terms of operating system selection, the overall performance of Win11 is slightly better than that of Win10, so it is recommended to use Win 11 operating system in principle. In the game test, Win11 has some problems in the number of frames in a few games such as the whole territory blockade, which affects the final evaluation. It is still better than Win10 in most games.
Single thread and multi-thread:
Single thread: AMD’s performance in single thread is quite fierce this time, completely surpassing i9-12900K, where the performance of single thread has been greatly upgraded, with an increase rate of 9%. Compared with the previous generation Ruilong 9 5900X, it reached nearly 26%.
Multithreading: Compared with Intel’s i9-12900K, the performance of multithreading has improved by 17%. Compared with the previous generation Ruilong 9 5900X, it reached nearly 35%.
This time AMD introduced the memory EXPO function, which can upgrade the memory from 4800 to 6000 with one click. Here, the tests were carried out under Win10 and Win11 respectively:
-Compared with 4800 frequency, we can still see some performance improvement at 6000 frequency, but the overall improvement is not obvious.
-Under different operating systems, Win 10 is slightly sensitive to memory frequency.
-AMD has actually done quite well in memory optimization this time, and 4800C40 can get good performance under the default parameters of crotch pulling. Compared with Intel’s two-terminal compatibility, it has obvious advantages in performance.
Detailed data table of mode test:
Finally, the last CPU ladder diagram is for your reference. The performance part only compares the test items related to CPU, and does not include the results of the game performance test. Since 2017, the system, driver and BIOS have great influence on CPU performance, so this table is only for directional reference. Due to the change of the graphics card in the ladder diagram, there will be a temporary shortage of power consumption.
Because my testing method is mainly aimed at daily use environment, the high weight of single thread is not friendly to HEDT CPU.
Conclusion:
About CPU performance:
As can be seen from the final ladder diagram, AMD 7000 series CPU reached the summit with only the second flagship, and this time it is not the kind of multi-core that AMD used to fight for, but relies on better single-core performance and better multi-core optimization as a whole. Therefore, the data given by AMD at the press conference is quite reliable. The increase of IPC by more than 10% and the increase of frequency bring about a huge increase.
About collocation alone:
AMD 7000 series CPU has obvious optimization in game performance, regaining the throne of game performance from Intel. The two families are now in a state of mutual involvement.
About disk performance:
AMD’s disk performance has also made significant progress, and it is hard to say what obvious advantages Intel has in the field of disk performance.
About power consumption:
AMD’s power consumption this time is larger than that of the previous generation, but it will be significantly lower than Intel’s, which is probably Ruilong 9 7950X 210W, Ruilong 9 7900X 180W, Ruilong 7 7700X 130W and R5 7600X 110W W.. However, in order to enhance the performance of the game, AMD runs more unrestrained under Win 11, and the energy consumption ratio of comprehensive use will become weaker.
Some suggestions on AMD 7000 series;
At present, it is enough to match the memory with 4800 frequency, especially considering the difference between 4800 and 6000, which means little.
Win11 is still recommended on the operating system, which will have certain performance differences.
In addition, we should pay attention to the choice of radiator, which will have a certain amount of influence on CPU performance. If possible, we can find a way to install an offset fastener so that the radiator can be pressed above the CORE DIE as much as possible.
Generally speaking, AMD’s platform replacement this time is quite successful, which not only makes the CPU more durable, but also takes this opportunity to renovate the entire motherboard architecture at one time and put the main specifications such as memory and PCIe in place at one time.
This clearly tells us that,After AMD’s AM4 platform, the whole company’s research and development has entered the track of stable iteration, so no matter how AMD 7000 series CPU wins or loses in the follow-up comparison, the competitive pattern between AMD and Intel will remain for a long time.
