AMD has expanded the L2 and L3 caches which will improve performance.

Now that AMD has released MSRP consumers can now select a model for those who want to upgrade their existing processors. Check with your motherboard CPU support list before replacing the processor and also check for a BIOS update for supporting new model processors.

AMD has mentioned the R9 3950X will be available in September. The R5 3400G and R3 3200G APUs are rebadged to flesh out the CPU lineup. The popularity of AMDs integrated graphics is extraordinarily good.

The R9 3900X has 64 MB of L3 cache which will improve performance along with 12 cores and 24 threads. More threads has some limitations as main memory is a bottleneck which is why L3 caches are larger with the Zen 2 lineup.

The move to PCI Express 4.0 is mostly to benefit the SSD and the CPU/Southbridge links. Video cards do not need that much bandwidth.

Windows 10 version 1903 runs well on the Zen processors. Windows is compiled to run on even very old hardware so AMD simply tuned the instruction set to maximize execution. The AMD Zen competes well against even Intel’s more expensive processors.

The X570 motherboards now are supporting 128GB of memory now that 32GB DDR4 sticks on the market. G.Skill made some DDR4 with dual rows of 8 gigabit chips to emulate a 16 gigabit RAM chip. More on this will follow.

The default for the Zen 2 infinity fabric is 1600 MHz which makes DDR4-3200 the best bet for memory for maximum speed. The Zen 2 infinity fabric is not able to take advantage of faster RAM.
