This afternoon, amd once again announced the Ruilong 7000 series processor. This generation can be said to be the largest upgrade of Ruilong in five years. The CPU is upgraded to 5nm zen4, the IOD core is upgraded to 6nm process and integrated with core display. It also supports ddr5 memory and PCIe 5.0. On the performance improvement that we are most concerned about, amd also gives some data, for example, the single core performance is improved by 15% and the frequency is more than 5GHz. In the rendering software blender, the 16 core Ruilong 7000 flagship SKU is 31% faster than the core i9-12900k of friends**
Single core increased by 15% and multi-core led by 31% - these data look good and powerful, but when you think about it, the comparison given by AMD is a little confused.
The first is the single core performance. Compared with the previous performance improvement of IPC given by AMD, the Ruilong 7000 said that the single core performance was improved by 15% (running the R23 test with better performance of AMD). As we all know, the single core performance is related to IPC and frequency. The maximum frequency of the Ruilong 7000 demonstrated by AMD reached 5.5ghz, which is at least 10% higher than the current Ruilong 5000.
If the frequency is increased by 10% and the overall single core is increased by 15%, then the IPC improvement range of 5nm zen4 should be 5% or less, which is completely unbelievable. not to mention the rumor that the IPC has increased by 15% or even more than 20%. Now zen4 has changed its architecture and supports ddr5, but the IPC has not improved significantly**
Not only the IPC performance is questionable, but the multi-core performance is also very metaphysical. Compared with i9-12900k, the blender performance of Ruilong 9 5950x is 31% better than that of 12900k. Obviously, the multi-core performance is also improved by more than 15% with a single core. This is another paradox. Due to the poor multi-core parallelism and frequency, the multi-core performance is usually improved less than that of a single core.
In any case, the single core and multi-core performance improvement of the Raptor 7000 announced by AMD has some metaphysics. Think about it, there is something wrong, but now there is not much data to support it. After all, amd has not lifted the ban**
How much is the single core and multi-core improvement of the Ruilong 7000? This question has aroused heated discussion among netizens who care about the Ruilong 7000 at home and abroad. There are various opinions, and there is no authoritative explanation yet.
