New Zen 4 and EPYC Genoa Details: AMD signs Exclusive Deal for 5nm Node

    AMD Ryzen 4000

    While we are still at 7nm Zen 2, AMD has already gone on to sign an exclusive deal with TSMC for Enhanced 5nm node. Ever since AMD moved on from GlobalFoundry (which fabricated the 1st Gen Ryzen) to TSMC, they have been going strong. AMD’s chips have been clocking higher and in general, have higher yields. Now after the successful launch of the Zen 2, also being produced on TSMC’s 7nm node AMD is eyeing for their next big leap to the 5nm with Zen 4.

    After Huawei dropped their 5nm orders and also lower orders for their 7nm wafers, TSMC has been eased off the production burden. The reports from ChinaNews have shown that AMD will have first dibs on the Enhanced 5nm node for their Zen 4 line up. As usual Zen 4 will start with EPYC Genoa server CPUs before it moves on to Ryzen 5000 desktop processors.

    AMD EPYC Genoa, DDR5, PCIe 5.0 Details

    The AMD EPYC Genoa was revealed during the roadmap shown at the EPYC Rome event. It seems like AMD will be the first to bring DDR5 memory to Servers followed by desktop. They have been pioneering new tech, as the Zen 2 was also the first to support PCIe 4.0 last year. We might also see the Bandwith double as Zen 4 might go from PCIe 4.0 to PCIe 5.0, which will see effectively see the speed reach 128Gbps across 16 lanes.

    We will also be seeing a socket change as we will be going from the SP3 Socket Platform to the SP5 platform for the EPYC Genoa processors.


    TSMC’s 5nm process (N5) is expected to deliver around 15% better performance over the 7nm process (N7) at the same power or 30% better power efficiency at the same performance. The enhanced 5nm process (N5P) is going to further improve this by 7% performance at the same power over N5 and 15% power savings at the same performance over N5.

    We can also expect these features to trickle down to the Threadripper and Ryzen lineup at least for the memory. We might see the first socket change from AM4 which debuted back with 1st Gen Ryzen.

    The EPYC Genoa will also be able to take advantage of the new Compute DNA (CDNA) GPUs. CDNA is the High process compute (HPC) equivalent of the RDNA series of GPUs. These CDNA GPUs are tailor-made for compute applications. EPYC Genoa processors are expected to debut in 2021. They will go on to feature on the El Capitan supercomputer which is to deliver 2 Exaflops of performance in 2023.
