Top 5 AMD Zen 4 Based 7000 series desktop CPUs Features

Updated: Oct 19

On 30th August, AMD announced their new desktop CPU lineup – the new AMD 7000 series desktop processors based on AMD’s all new Zen 4 architecture.

AMD announced four desktop processors, Ryzen 5 7600X, Ryzen 7 7700X, Ryzen 9 7900X and top of the line Ryzen 9 7950X. It is worth mentioning that AMD did not announce the 7800X. Maybe, they are planning to launch it for later sometime.



AMD Ryzen 7000 Specs

AMD has confirmed 4 new desktop processors till now and the instructions per clock cycle have increased by 13% as per AMD. Even clock speeds per core are increased.

Also you will see their top of the line Ryzen 9 processors will have 12 cores for 7900X and 16 cores for 7950X processors with double thread counts because of SMT (Simultaneous multi-threading).

Price and Availability

AMD has said that the new AMD 7000 series processors will hit the markets on September 27th. AMD has surprised us all with their pricing. The pricing of the processors is similar to the Ryzen 5000 series desktop processors. Even the top-of-the-line 7950X is cheaper than then announced price of 5950X which was $799.

List of new Zen 4 Features

We have listed few of the most notable features of new 7000 series by AMD.


1. The new AMD 7000 series processors will be based on the all-new AMD Zen 4 architecture. This new Zen architecture is based on TSMC’s new 5nm fabrication process, making the 7000 series the world’s first desktop processors to use the 5nm fabrication process. This will reduce the power consumption by processor further and gives you more performance per clock cycle.

The Zen 4 architecture supports up to 16 Cores and 32 Threads and up to 80MB of shared cache. Shared cache means lower latency while processing so better performance in gaming as well as daily task.


2. New supports like the PCIe lanes, new PCIe gen 5.0 Storage and industry leading DDR5-5200Mhz RAM and. It is worth noting that the Zen 4 architecture supports only DDR5 RAM and not the DDR4.

Zen 4 processor's lanes, all of its PCIe lanes are PCIe 5.0 and there are a total of 28 lanes. The first 16 PCI Express lanes will be used for a single x16 PCIe slot, or they can be split into two x8 slots. AMD's requirements only enforce PCIe 5.0 on the X670E boards, which means PCIe 4.0 will be applicable to lower cost motherboards.

The new Zen 4 architecture supports the AMD’s new AM5 socket which is based on LGA 1718, compared to PGA in Zen 3. So, you will need the new AMD 600-series Motherboards for these new processors


3. AMD has finally able to achieve up to 5.7GHz boost clock speed on their top of the line 7950X based on the Zen 4 architecture which is 800MHz more than the 5950X. The Ryzen 9 7950X will have a TDP of massive 170W and up to 230W when overclocked. Also, the least powerful 7600X has a TDP of 105W. With this new architecture, AMD claims up to 13% IPC improvement over prior generation, up to 29% improvement in single threaded performance and up to 45% improvement in multi-threaded performance over the last generation and also up to 28% gains in performance per watt. AMD also claims that the 7950X is 11% faster in gaming that the Intel’s beast 12900K and even the baby boy, 7600X is 5% faster than the 12900K in gaming.

The new Zen 4 architecture supports up to 25% more memory bandwidth per core than the previous generation.

4. All the new processors based on Zen 4 architecture come with an additional I/O die based on 6nm that has the RDNA2 graphics for display output (earlier AMD’s X series processors did not come with native display output). It supports up to four display outputs, including DisplayPort 2 and HDMI 2.1. However, the RDNA2 graphics on these processors is very low powered and can only be used for display output, you cannot expect gaming on this. It also supports AVX-512 and VNNI.


5. The Zen 4 compute die is said to be of size 72.23mm^2 which is smaller than the compute die on the previous generation processors (83.74mm^2). It is predicted that there are ~5.57B transistors for the Zen 4 architecture compute die compared to 4.51B for Zen 3 architecture compute die. However, the AM5 Socket is backwards compatible with AM4 coolers.
