AMD may choose to release
the Ryzen 7000 series desktop processors on August 29, 2022, at 8:00 pm ET, after which the related products will be officially available for sale at 9:00 am ET on September 15, 2022. As the Ryzen 7000 series release time is nearer, more test data has emerged on the web.
Recently, Twitter user @9550pro released the cache and memory benchmark test results of the Ryzen 9 7900X in AIDA64, showing that the Zen 4 architecture seems to have a greater improvement than the Zen 3 architecture in terms of L3 cache bandwidth and latency. The Ryzen 9 7900X has 12 cores and 24 threads, a base clock of 4.7GHz, a boost clock of 5.6GHz, a TDP of 170W, and a 64MB L3 cache.
The benchmark data shows that its read speed is 1494.8GB/s, the write speed is 1445.7GB/s, the copy speed is 1476.6GB/s, and the latency is 10.1ns. Not sure about the configuration of the test platform, but there is no doubt about the use of DDR5 memory. Compared with the Core i9-12900K, this result has a 47% increase in bandwidth, and an increase of more than 50% compared with the Ryzen 9 5900X processor of the previous generation Zen 3 architecture. As for latency, the Core i9-12900K has twice the latency of the Ryzen 9 7900X.
