AMD officially released the Zen 4 architecture of the Ryzen 7000 series desktop processors this morning，The new generation of processors is built on TSMC's 5nm process，The new architecture improves the IPC of the existing product by 13%，And support DDR5 memory and PCI-E 5.0，The new AM5 platform will be the starting point of a new era for AMD，AMD promises support for new platforms until at least 2025。
The Ryzen 7000 series processors are very different in appearance from the previous Ryzen processors.，AM5 platform will use LGA 1718 interface，No more pins on the back of the CPU，Now the CPU needs to be fixed with a buckle，But the radiator is compatible with the existing AM4，At least no need to replace the radiator。
The number of core displays of the Ryzen 7000 series processors has not changed significantly compared with the previous generation，But the frequency increased significantly，And double the L2 cache capacity per core from 512KB to 1MB，And added support for the AVX-512 instruction set，Still 8 cores and one CCD，32MB shared L3 cache on each CCD。
The new Zen 4 architecture improves IPC by 13% compared to the Zen 3 architecture，The Ryzen 7000 series desktop processors use the more advanced TSMC 5nm process，The highest frequency can reach 5.7GHz，800MHz higher than the Ryzen 5000 series，The combination of the two improves the single-threaded performance of the Ryzen 7000 processor by as much as 29%。
Compared with Ryzen 5000 series processors， The Ryzen 7000 processor delivers a 29% increase in gaming performance，44% increase in computing performance for creators，Energy consumption ratio increased by 28%。
Compared to the rival Core i9-12900K，Game performance improved by 11%，44% increase in computing performance，The energy consumption ratio has increased by 47%，This difference is not small，Of course, the next-generation Core processor top Core i9-13900K has 8 more E-Cores，The frequency boost is not too low，plus cache changes，It's hard to say what will happen。
Ryzen 9 7950X compared to Ryzen 9 5950X，The most obvious improvement in game performance is "Tomb Raider"：shadow"，Performance improved by as much as 35%，Among the creator projects that focus on multi-threaded performance, the most obvious improvement is V-Ray Render，Up to 48% increase。
This comparison is more interesting，Performance comparison of Ryzen 9 7950X and Ryzen 9 5950X at the same power，The performance of the new processor has increased by 74% at TDP 65W，10537% at W，170W has a 35% performance improvement，The new architecture and new process are really big improvements in terms of energy efficiency。
The front end of the Zen 4 architecture is redesigned，And supports AVX-512 instruction set，But it's not clear which AVX-512 subsets AMD will support，It can be determined that the basic AVX-512F is available，Also includes VNNI；
In addition, AMD's AVX-512 implementation method is different from Intel's，Intel built a true 512-bit wide SIMD unit inside the processor core to execute AVX-512 instructions，while AMD does not，Zen 4 will use 256-bit SIMD to execute AVX-512 instructions in two clock cycles，The advantage of this is that it doesn't cost extra transistors，And when running AVX-512 instructions, there is no need to downclock execution like Intel processors.。
Zen 4 Architecture Improvements Inside，The biggest contribution to IPC improvement is the new front end，followed by the load/store system，followed by the branch predictor、Execution engine and doubled L2 cache。
Thanks to TSMC's new 5nm process，Zen 4's CPU cores double the L2 cache capacity compared to the previous generation，But the area of core + L2 cache is still 18% smaller than Zen 3，Each core area is only 3.84mm 2，They also compared with Alder Lake's P-Core，Each core of Zen 4 is almost half the size of Golden Cove，It can be seen that AMD does have an advantage in chip size，Reduced manufacturing costs to a certain extent。
What frequency of DDR5 memory does the Ryzen 7000 processor support?，In fact, today's press conference did not explicitly say，But from the DDR5-5200 listed on the PPT in 2022， Ryzen 7000 should support JEDEC standard DDR5-5200 memory。
ADM Ryzen 7000 processor debuts four models，It will go on sale on September 27th，include：
