The Radeon RX 5700 series is the first implementation of AMD’s 7-nanometer Navi GPU and RDNA architecture. AMD will be launching the FX 5700 series on July 7, 2019 which is just 2 days before the new Geforce cards launch..
The new pricing is as follows:
- Radeon RX 5700 XT 50th Anniversary Edition—$449 (down from $499)
- Radeon RX 5700 XT—$399 (down from $449)
- Radeon RX 5700—$349 (down from $379)
AMD obviously has reacted to the pricing of the GeForce SUPER lineup. AMD said, “We embrace competition, which drives innovation to the benefit of gamers. In that spirit, we are updating the pricing of our Radeon RX 5700 series graphics cards.”
AMD will have their first generation of TSMC 7nm refined considerably heading into 2020 which should see the second generation of RDNA architecture. It’s also reasonable to expect that AMD will be working with TSMC to improve the yields for larger silicon block devices. At present AMD has been forced to use a chiplet design to be able to keep yields at acceptable levels.
Intel mentioned their Saphire Rapids which is intended to replace Ice Lake for the enthusiast market. Intel expects it to be available in 2021. Further out Intel has mentioned Granite Rapids as their first move into 7nm which is expected in 2022.
AMD has also been launching their Zen 2 based Ryzen 3000 series processors which will bring PCI Express 4.0 to the consumer market. The SSD sector has been pushing for more bandwidth for quite some time. Doubling the bandwidth should placate the SSD sector for while before somebody designs a faster product but PCI Express 5.0 is already to go so SSD products have a second doubling of bandwidth to cope with.
TSMC introduced a 6nm process while they are also working towards the 5nm line which is nearing completion. EUVL is needed at the smaller nodes and it has been successful at making mobile devices as well as small logic hardware. Larger monolithic devices are not yielding nearly as well.
Samsung has been using EUVL for making memory chips and they are working with nVidia to make their Ampere architecture ready for 2020. Most likely there will be several redesigns as the engineers work to get monolithic hardware at acceptable yields.
The critical dimension can be out of alignment so that eteching does not reach the junction. Focusing is hard with EUV lamps making reflections a serious problem. Keeping the mask in perfect alignment is very challenging.
