AMD have announced a 7nm Vega refresh, this came as a surprise as previous rumours suggested that the Vega refresh would be produced on a 12nm process. 7nm Vega will be more power efficient and it is aimed at compute performance and machine learning rather than gaming. The process size reduction is a good sign as current generation Vega is too power hungry so hopefully we will see improvements here. We don’t know anything more about Navi except that it will likely come in 2019 and will use the 7nm+ arcuitecture. In 2020 the “next-gen” GPUs will come, we don’t even know the code name for these nor do we have any details however it will be based on the 7nm+ architecture and feature next generation memory, so probably HBM3 or GDDR6.
Regarding processors, the current Ryzen processors are going to become cheaper and the 2000 series will be released, there will also be a second generation threadripper that will land in the second half of 2018. The Ryzen 1800X will be cut from $499 to $340 and the Ryzen 5 1600x will go from $249 to $219 and most of the other current generation products will also see a reduction in price.
There will be Ryzen + Vega APUs both for mobile and desktop coming in Q1 2018, the first releases will come in February. The desktop variants will be the 2400G and the 2200G, these both have 4 cores and 8 threads but the higher model has a higher price, slightly higher clock speeds and more CUs. These were compared to the current generation intel processors in a graphics test, of course the AMD graphics give Intel’s solution a kick up the backside as usual, AMD’s integrated Vega graphics can also be overclocked which gives a good performance boost.The Ryzen 2000 series is going to be released in April instead of February as rumoured previously, along with the 400 series motherboards. AMD has confirmed that we will see a power reduction and higher clock speeds and that the Ryzen 7, 5 and 3 processors will all be released at the same time instead of the staggered release of the current generation. The 3000 series, which will feature Zen 2 instead of Zen + cores will be released at some point in 2019. As AMD has promised previously, Ryzen + will be compatible with the current AM4 socket and the current 300 series motherbaords. These have both backward and forward compatibility, meaning that Ryzen 1 processor will work in a 400 series motherboard and a Ryzen + processor will work with a 300 series motherboard.
The new processors are also coming with precision boost 2, and updated version that does not lower the clock speeds if more than 2 cores are being used provided the processor is within its specified TDP. In theory this should allow the processors to reach and maintain higher clock speeds even while using multiple threads. It also features per core boost, which should benefit applications that a single, faster thread.
One of the slides from the presentation states that there will be “silicon improvements for cache and memory speeds and latency”. This suggests we will see faster cache with lower latency and better stability and support for higher memory clocks, which is a very good thing, considering how well Ryzen performance scales with memory speed.
AMD have stated that there will be a 10% performance increase compared to the 14nm process, this may even be higher depending on how effective the other changes AMD implement are.
The Threadripper 2000 series will launch at some point in the second half of 2018 and will presumably feature the same cache and clock speed improvements, as Ryzen, but we don’t know much else yet.
