In addition to AMD's reveal of 7nm GPUs used in its Radeon Instinct MI60 and MI50 graphics cards (aimed at machine learning and other HPC acceleration), the company teased a few morsels of information on its 7nm CPUs. Specifically, AMD teased attendees of its New Horizon event with information on its 7nm "Rome" EPYC processors based on the new Zen 2 architecture.
Tom's Hardware spotted the upcoming Epyc processor at AMD's New Horizon event.
The codenamed "Rome" EPYC processors will utilize a MCM design like its EPYC and Threadripper predecessors, but increases the number of CPU dies from four to eight (with each chiplet containing eight cores with two CCXs) and adds a new 14nm I/O die that sits in the center of processor that consolidates memory and I/O channels to help even-out the latency among all the cores of the various dies. This new approach allows each chip to directly access up to eight channels of DDR4 memory (up to 4TB) and will no longer have to send requests to neighboring dies connected to memory which was the case with, for example, Threadripper 2. The I/O die is speculated by TechPowerUp to also be responsible for other I/O duties such as PCI-E 4.0 and the PCH communication duties previously integrated into each die.
"Rome" EPYC processors with up to 64 cores (128 threads) are expected to launch next year with AMD already sampling processors to its biggest enterprise clients. The new Zen 2-based processors should work with existing Naples and future Milan server platforms. EPYC will feature from four to up to eight 7nm Zen 2 dies connected via Infinity Fabric to a 14nm I/O die.

The new 7nm Zen 2 CPU dies are much smaller than the dies of previous generation parts (even 12nm Zen+). AMD has not provided full details on the changes it has made with the new Zen 2 architecutre, but it has apparently heavily tweaked the front end operations (branch prediction, pre-fetching) and increased cache sizes as well as doubling the size of the FPUs to 256-bit. The architectural improvements alogn with the die shrink should allow AMD to show off some respectable IPC improvements and I am interested to see details and how Zen 2 will shake out.

The first whiffs of Zen 2 are finally reaching us. During the AMD press conference at Computex today CEO Dr. Lisa Su stood on stage and held up the first public showing of Rome, the codename for AMD’s next-generation EPYC enterprise processor family.
Rome is exciting because it will be the first 7nm high-performance processor in the market, and it makes the 10nm production problems that Intel is having all the more troublesome for the blue-chip giant. And because Rome will be socket compatible with the currently shipping EPYC systems, there is a huge potential for market penetration through 2019.
AMD stated that it would be sampling Rome-based Zen 2 processors to partners in the second half of 2018, with launch in 2019. AMD does have silicon back in the labs, up and running. No more timing detail was given than that.
The competitive statement of AMD putting timeframes on its 7nm server processors, rumored to be going up to 64-cores PER SOCKET, while Intel struggles with its move to 10nm, is significant. AMD still targets a 5% market share for server processors by the end of the year, but it might be 2019 that proves to be a more significant year for the company’s drive back into the server space.

The Total War series has come a long way, from campaign maps that played like a Risk game and cloned troopers in the battlefield to gorgeous landscapes with much more realistic movements and incredibly detailed units in battles. On the other hand the long awaited next installation of Rome: Total War might have gone a bit too far. It is not necessarily the obscene amount of time it takes to process the AI's turns nor the inevitable bugs that crept through the QA process; the ability to easily distribute 100MB patches has degraded every publishers QA process to a joke when you compare it to the days of dial-up. Instead it is the realization that the niggling feeling as you push the End Turn button that you have left something undone is caused by the fact that you did nothing that turn at all. The campaign map in Total War has never been fast paced nor is it meant to be, instead there had always been a million micromanagement tasks to be completed every turn whereas in this new Rome you often have nothing to do but bash on the end turn button for a few seasons.
It is as Rock, Paper, SHOTGUN comment "I feel that Total War should be a coiled armadillo rather than Rome IIs jellyfish."
"So then. I am usually in the Total War apologist camp, but not this time. I am not sure if it’s because I had a better experience with Shogun 2, or whether there’s some kind of allergy due to over-exposure going on, but Rome II rubbed me up the wrong druid."
