Near the beginning of AMD's Investor Relations slidedeck sits a glimpse at what we will see from the company, except for a date with Navi. Some time before summer break we will see the release of the second generation of Ryzen Pro Mobile chips (picture not to scale), which will bring Zen 2 and improved graphics to your office devices.
Just after the mobile chips and in time to give you a reason not to go outside the third generation of Ryzen desktop chips will hit the market, just as AMD promised. We already have a good idea about what those chips will be called as well as their specifications; Tim covered it in length here if you have yet to memorize all the models.
We will also see Thirdripper or as The Tech Report prefers, Threadripper the Third, though we lack any information on the date or models, you should expect to see it before the end of the year with even more cores running at a higher frequency.
AMD will also be releasing a Zen 2 based EPYC family, for chiplet fans everywhere! They suggest it will be twice as fast as the previous generation overall, up to four times as fast in certain floating point operations and as is tradition it will be compatible with the current sockets on EPYC motherboards so you can do a quick and easy drop in upgrade.
"Can you really call something a leak if the company released it on purpose? AMD's just released a slide deck for its investors, and buried in those slides are a few tiny nuggets of interesting information. Let's take a quick peek into the red team's path ahead."

Spotted by HardOCP, Paul from Red Gaming Tech recently shared leaked information from a source with a reputation of being reliable (from past leaks about 7nm GPUs) who claims that AMD will be announcing a plethora of products at Computex in June to setup for the launch of Zen 2-based 7nm "Matisse" Ryzen 3000 desktop processors, X500 series chipset-based motherboards, and 7nm Navi-based consumer gaming graphics cards on July 7th (The 7th for 7nm I guess).

As a refresher, Zen 2 is the next major architectural jump for AMD while also pushing a new smaller process node. AMD has not yet revealed all the details about Zen 2 especially about consumer chips, but the new microarchitecture is said to feature tweaks to the front end that along with clockspeed bumps from the TSMC 7nm process will allow them to realize notable IPC and single threaded performance gains. When talking about EPYC 2 "Rome" server processors (Zen 2 based) AMD hinted at changes to branch prediction and pre-fetching as well as increased cache sizes and larger FPUs (256-bit), for example. The move to 7nm allegedly allows AMD to hit similar power envelopes to Zen+ (12nm) Ryzen 2000 series processors while hitting much higher clockspeeds at up to 5.1 GHz boost on their top-end chip. While mobile chips may strike a finer balance between power usage and performance with the move to 7nm, on the desktop AMD is spending nearly all the power savings on performance (which makes sense). Note that it is still not officially official that AMD is using a scaled down EPYC setup with more than one 7nm (TSMC) CPU die and a separate IO die (14nm Global Foundries), [they only teased a chip at CES with an IO die and a single CPU die] but I am of the opinion that that particular rumor makes more sense than otherwise so am inclined to believe this is the case.
Ryzen 3000 series processors feature an IO chiplet along with what is rumored to be up to two CPU chiplets (image credit: Tom's Hardware).
From previous leaks, Ryzen 3000 is said to cover all the bases from six core Ryzen 3 3300 series chips to midrange eight core Ryzen 5 and on up to 12 and 16 core Ryzen 9 CPUs that move beyond a single CPU die to two 7nm CPU dies that feature eight cores each. In fact, the top end Ryzen 9 3850X is supposedly a 16 core (32 thread) monster of a desktop chip that has a base frequency of 4.3 GHz and can boost up to 5.1 GHz with a 135W TDP (which when overclocked will likely draw dramatically more like we've seen with both AMD and Intel's top end consumer chips) and price tag of around $520 (400 pounds). The Ryzen 7 3700 and 3700X are 12 core (24 thread) models with TDPs of 95W and 105W respectively with the non-x SKU clocked at 3.8 to 4.6 GHz and the 3700X clocked at 4.2 GHz base and 5 GHz boost. The Ryzen 5 3600 and 3600X are the top end single CPU die models (though a 2x single CCX per die chips might be a reality depending on yields) at eight cores and 16 threads. The Ryzen 3 3300 series parts represent the low end which is now interestingly six cores (oh how times have changed!). Perhaps most interesting of the leaked chips are the Ryzen 5 3600G (~$207) and the Ryzen 3 3300G (~$130) though which feature Navi 12 integrated graphics (presumably these processors combine one 7nm CPU die, one 7nm GPU die, and one 14nm IO die) with 15 and 20 CUs respectively.
As for motherboards, in general the new chips will use the AM4 socket and will be compatible with older 300 and 400 series motherboards with a BIOS update though the top end chips may well necessitate a new X570 or other X500 series motherboard with better power delivery especially for enthusiasts planning to attempt stable overclocks.
Unfortunately, on Navi details are still a bit scarce but the new architecture should bring performance enhancements even beyond Radeon VII (Vega on 7nm). Allegedly due to issues with TSMC, Red Gaming Tech's source believes that Navi might be delayed or pushed back beyond the planned mid-summer release date, but we will have to wait and see. As TSMC ramps up its partial EUV enhanced 7nm node it may free up needed production line space of the current 7nm node for AMD (to fight with others over heh) to meet its intended deadline but we will just have to wait and see!
Take these rumors with a grain of salt as usual but it certainly sounds like it is hoing to be an exciting summer for PC hardware! Hopefully more details about Ryzen 3000 and Navi emerge before then though as that's quite a while yet to wait. Of course, Zen 2 APUs are not coming until at least next year and AMD is still not talking Zen 2 Threadripper which may not see release until the fall at the very earliest. I am very interested to see how AMDs chiplet based design fares and how well they are able to scale it across their product stack(s) as well as what Intel's response will be as it presses on with a fine tuned 14nm++ and a less ambitious 10nm node.

What's in a name? Depending on how much you read into it, quite a bit, depending on what you infer from product code 2G16002CE8JA2_32/10/10_13E9. There are some very interesting rumours floating around the net today which suggest AMD might have another big win on their hands. They provided much of the hardware for the release of the two major consoles way back in 2013 and there have been recent statements they will be inside the next generation of XBox. Now that NVIDIA is working on supporting Active Sync that benefit is a little less clear in the long term but at least for now they are a little late to the game.

The image, from from a source that has a rather impressive track record, demonstrates the decoding process - and pay close attention to the letter "G", the second character in the string, which presumably indicates that this intended for a game console. The source also suggests that this new chip will be a Zen 2 and Navi based APU called Gonzolo, with eight cores clocking between 1GHz to 3.2GHz with 4MB of L2 cache and 16 MB of L3 cache. There is less information on the "Navi 10 Lite" GPU, apart from a belief that it's core will be running at a frequency of at least 1GHz.

This is great news for AMD, who have been enjoying the royalties from the sales of consoles and could use the fresh injection of cash as gamers upgrade once the consoles launch.

If the rumours The Inquirer are helping spread are true then AMD really does believe the third time's the charm. The new series of Ryzen 3000 chips will use Zen 2 cores and will follow Intel's addition of a 9 series, though the quoted price of £400 for the Ryzen 9 3850X is a lot more attractive than Intel's pricing. That chip will sport a 5.1GHz peak clock on its pair of Zen 2 dies with eight cores apiece, though the 135W TDP will need some taming.
Check out the variety of other chips in the Ryzen 3, 5, and 7 families which have leaked out.
"The upcoming third-generation Ryzen chip, slated for release next year, will be based on Team Red's Zen 2 architecture, the successor to its rather successful Zen architecture found in Ryzen 1 and 2 CPUs and EPYC server processors."

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.
AMD CEO Lisa Su holding up "Rome" EPYC CPU during press conference earlier this year.
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.

WCCFTech found some rumors (scroll down near the bottom of the linked article) about AMD’s upcoming EPYC “Rome” generation of EPYC server processors. The main point is that users will be able to buy up to 64 cores (128 threads) on a single packaged processor. This increase in core count will likely be due to the process node shrink, from 14nm down to GlobalFoundries’ 7nm. This is not the same as the upcoming second-generation Zen processors, which are built on 12nm and expected to ship in a few months.
Rome is probably not coming until 2019.
But when it does… up to 128 threads. Also, if I’m understanding WCCFTech’s post correctly, AMD will produce two different dies for this product line. One design will have 12 cores per die (x4 for 48 cores per package) and the other will have 16 cores per die (x4 for 64 cores per package). The reason why this is interesting is because AMD is, apparently, expecting to sell enough volume to warrant multiple chip designs, rather than just making a flagship and filling in SKUs with bin sorting and cutting off the cores that require abnormally high voltage for a given clock rate as parts with lesser core count. (That will happen too, as usual, but from two different intended designs instead of just the flagship.)
If it works out as AMD plans, this could be an opportunity to acquire prime market share away from Intel and their Xeon processors. The second chip might let them get into second-tier servers with an even more cost-efficient part, because a 12-core die will bin better than a 16-core one and, as mentioned, yield more from a wafer anyway.
Again, this is a common practice from a technical standpoint; the interesting part is that it could work out well for AMD from a strategic perspective. The timing and market might be right for EPYC in various classes of high-end servers.
Beating AMD and Analyst Estimates
January 30th has rolled around and AMD released their Q4 2017 results. The results were positive and somewhat unexpected. I have been curious how the company fared and was waiting for these results to compare them to the relatively strong quarter that Intel experienced. At the Q3 earnings AMD was not entirely bullish about how Q4 would go. The knew that it was going to be a down quarter as compared to an unexpectedly strong third quarter, but they were unsure how that was going to pan out. The primary reason that Q4 was not going to be as strong was due to the known royalty income that AMD was expecting from their Semi-Custom Group. Q4 has traditionally been bad for that group as all of their buildup for the holiday season came from Q1 and Q2 rampings of the physical products that would be integrated into consoles.
The results exceeded AMD’s and analysts’ expectations. They were expecting in the $1.39B range, but their actual revenue came in at a relatively strong $1.48B. Not only was the quarter stronger than expected, but AMD was able to pull out another positive net income of $61M. It has been a while since AMD was able to post back to back profitable quarters. This allowed AMD to have a net positive year to the tune of $43M where in 2016 AMD had a loss of $497M. 2017 as a whole was $1.06B more in revenue over 2016. AMD has been historically lean in terms of expenses for the past few years, and a massive boost in revenue has allowed them to invest in R&D as well as more aggressively ramp up their money making products to compete more adequately with Intel, who is having their own set of issues right now with manufacturing and security.
