A Brief Note on AMD Ryzen 9 7900X
While the AMD Ryzen 9 7950 is a $699 top-of-the-line CPU in the AMD Ryzen 7000 Series, the AMD Ryzen 9 7900X is $150 less and looks like the most value-oriented processor. Even though Intel and Apple started designing processors using a hybrid architecture, AMD struck with their tried-and-tested “all powerful cores” for their Zen 4 based Ryzen 7000 Series CPUs. Specifically, the AMD Ryzen 9 7900X has 12 cores and 24 threads. Speaking of Zen 4, AMD completely revamped the architecture with Zen 4 that has 13% better IPC performance than previous generation architecture. With this new architecture, AMD had to let go of their popular AM4 socket and bring in a new AM5 Socket. Another thing AMD is popular is for their “Chiplet” designs. In the AMD Ryzen 9 7900X, the CPU consists of 3 chiplets, two of them are the Core Complex Dies (CCD) with 6 cores each and one Input – Output Die (IOD). Under the hood, each CCD consists of 8 CPU Cores. But in case of the AMD Ryzen 9 7900X, AMD disables two cores in each CCD. The AMD Ryzen 9 7950X has the same CCDs but utilizes all the 8 CPU Cores per CCD. In order to keep the cost down, AMD designed the CCD using TSMC 5 nm node and the IOD using TSMC 6 nm node. There are some big changes in terms of memory a well. Unlike Intel’s 13th Gen CPUs that support both DDR4 and DDR5 memory, AMD made their Zen 4 CPUs compatible with only DDR5 memory. Coming to the L2 Cache of the AMD Ryzen 9 7900X, it has L2 Cache of 1 MB per core. So, this makes the total L2 Cache of AMD Ryzen 9 7900X at 12 MB (12 * 1 MB). Coming to the L3 Cache, AMD divided this into two sections based on the Core Complex Dies i.e., each CCD Module gets 32 MB of L3 Cache. So, the total L3 Cache of the AMD Ryzen 9 7900X is 64 MB (1 * 32 MB).
Important Specifications of AMD Ryzen 9 7900X
12 Cores 24 Threads AM5 Socket Supports only DDR5 Memory Cache: L2 is 1 MB per core (Total 12 MB) and L3 is 32 MB per CCD (Total 64 MB) Total 28 PCIe 5.0 lanes (4 of them are reserved for chipset) RDNA2 based Integrated Graphics (base clock of 0.4 GHz and boost clock of 2.2 GHz) TDP is 170 Watts Manufacturing Node is TSMC 5 nm for CCD and TSMC 6 nm for IOD
A Brief Note on AMD Ryzen 5 7600X
As AMD announced the high-end CPUs in the form of the AMD Ryzen 9 7950X and the AMD Ryzen 9 7900X, we feel that not everyone is interested in spending that chunk of money. Hence, along with these powerful processors, AMD also launched the reasonably priced AMD Ryzen 5 7600X. This is where AMD will see a good sales number. Just like the AMD Ryzen 9 7900X, the AMD Ryzen 5 7600X is also based on a new architecture, the Zen 4. Apart from this, it also gets a brand-new socket, the AM5. Another similarity between the AMD Ryzen 5 7600X and its expensive and powerful comrades, is the support for only DDR5 memory and has only PCIe 5.0 support. With a launch price of $299 and the traditional 6 core 12 thread design, the AMD Ryzen 5 7600X is the contender for the best bang for the buck gaming CPU. Similar to the AMD Ryzen 9 7900X, the AMD Ryzen 5 7600X also supports only DDR5 up to 5200 MT/s. Coming to the frequencies of the AMD Ryzen 5 7600X, it has a base clock of 4.7 GHz and a boost clock of 5.3 GHz.
Important Features of Ryzen 5 7600X
