AMD announced its next-generation data centre processor, dubbed Rome, at a special event last week. We've been digging behind the. AMD's chiplet design approach is an evolution of the company's Now, the scalability of IO interfaces eats die-area that could be better spent. Bit longer answer, IO doesn't scale down very much, so instead of wasting expensive 7nm wafer space on IO, AMD has decided to move it off  how will the new IO die and chiplets deal with latencies compared.

AMD outlines its future: 7nm GPUs with PCIe 4, Zen 2, Zen 3, Zen 4

The pictures above makes clear that the IO dies of the Epyc and Ryzen desktop chip are not the same size. This makes obvious sense, as Epyc has more chiplets and memory channels to support. AMD IO producing the specialised parts on the least expensive node, AMD will save on production costs. Later, when the production costs of 7nm have dropped or when new nodes sizes become available, AMD AMD IO decide to switch the IO dies to a smaller process as well.

There is speculation if this AMD IO die will also support other types of chips like a gpu or AI accelerator. Marrying the Zen based x86 AMD IO die with these parts via the IO die will give AMD access to new flexibility to create truly custom and special purpose chips for a multitude of industries. No dummies Previous and current generation Epyc and Threadripper processors use up to two dummy dies.

The chip uses the dummy AMD IO to properly support the heat-spreader of the very large chips.

The engineering sample held up by dr. Su in the keynote clearly showed only a single Zen AMD IO die. While this could mean that an asymmetrical distribution of the dies is possible, it is much more likely that the final chip will contain an IO die with two Zen 2 chiplets.

This way, AMD can use cpus with up to 4 defective cores. To feed the widened execution units which were improved in AMD IO, the front-end had to be adjusted. For that reason, the branch prediction unit has been reworked.

This AMD IO improvements to the prefetcher and various undisclosed optimizations to the instruction cache. The size of the cache on Zen was 2, entries. The exact details of Zen 2 changes were not disclosed at this time.

The majority of the changes to the AMD IO involve the floating-point units. The most major change AMD IO the widening of the data path which has been doubled in width for the floating-point execution units. In Zen, AVX2 is fully supported through the use of two bit micro-ops per instruction. Likewise, the load and store data paths were bit wide.

DRIVER UPDATE: AMD IO

We shall see. Allegedly, no.

AMD is promising that all existing motherboards will be compatible with Rome chips, although you'll probably need to flash the ROM. Future mobile and desktop processors The main thing this news means AMD IO the future of mobile and desktop chips is that the next generation of Ryzen processors will use a similar structure: The shift to 7nm for laptops could be particularly interesting. Intel has had the lead for laptop power efficiency AMD IO years, so if AMD can indeed offer the same power efficiency benefits such as the same performance for half the power consumption then and could see some genuine competition in that market.

We can't see AMD shaking Intel's tree AMD IO desktop chips, however. Intel still has a clear lead for per-clock desktop performance here, and the bigger jump appears to be in power efficiency AMD IO than outright performance.

Perhaps it will surprise us on the desktop as well. For the same performance level, power is reduced by about 50 percent, or, conversely, at the same power consumption, performance is increased by about 25 percent. Zen 2 will also address AMD IO weak aspects of the original Zen.

AMD IO example, the original Zen used bit data paths to handle bit AVX2 operations; each operation was split into two parts and processed sequentially. In workloads using AVX2, this gave Intel, with its AMD IO bit implementation, a huge advantage.

Zen 2 doubles the floating-point execution units and data paths to be bit, doubling the bandwidth available and greatly improving the performance of this AMD IO. For integer workloads, branch prediction and prefetching have been made more accurate and some caches enlarged.
