AMD Ryzen 9 7900X, will be equipped with 12 cores and 24 threads. This CPU has a base clock of 4.7GHz, a boost clock of 5.6GHz, and a higher frequency for individual cores. The processor’s TDP is set at 170W, and with 76MB of cache (64MB L3 + 12MB L2), its performance will be similar to the Core i7-12700K.
The benchmark data shows that the memory read speed is 1494.8GB/s, the memory write speed is 1445.7GB/s, the memory copy speed is 1476.6GB/s, and the latency is 10.1ns. We don’t yet know what specs the entire system is running on, but it should be using DDR5 DRAM.
Ryzen 9 5900X, Ryzen 7 5800X3D and Core i9-12900K were tested in the same way (Ryzen platform with DDR4-3800, whileIntelplatform is running DDR5-6000 memory), the result is as follows:
As you can see in the benchmarks, the AMD Ryzen 9 7900X 12-core CPU is said to have a 47% increase in L3 bandwidth over Alder Lake and over 50% over its Zen 3-powered predecessor. The difference widens even further in terms of L3 copy metrics, with the chip being nearly 3x faster than the Alder Lake CPU. Latency-wise, the chip offered the lowest time, with an interconnect speed of 10.1ns, while the Alder Lake CPU had twice that, at 21.8ns.
