Blink and you miss it: AMD's keynote address this year was a whirlwind of primetime announcements for the company. The message is clear: AMD is committing itself to 7nm as the future process node that will drive the company's innovations starting in 2019. The first consumer products on 7nm will be the Ryzen 3rd Generation Desktop processors, using Zen 2 cores, offering more than competitive performance against Intel's best hardware. Also on the docket is a return to high-end graphics performance, with AMD set to release a 7nm graphics card that can spar blow-for-blow with the competition at the $700 price barrier.

AMD at CES 2019

One of the odd things about AMD’s announcements this show has been the tale of two halves. Normally a company will push out single major press release with everything in it. This year AMD discussed its news around Ryzen-3000 series mobile parts and AMD Chromebooks just as the show started, and we were all confused if this was going to constitute what was in the keynote or not – it would seem odd, after all, for the company to pre-announce its keynote announcements. Luckily, AMD has plenty to announce, and it’s all pretty juicy.

First up, CPUs. AMD presented its next generation 7nm desktop CPU, which is the 3rd Generation Ryzen.

Attacking the Mainstream CPU Market: Toe to Toe with Core i9-9900K

Ignore everything you might have heard about what AMD’s future desktop CPU is going to be. Here are most of the details you need to know.

The new parts, codenamed Matisse, will be coming to market in mid-2019 (sometime in Q2 or Q3). The processor the company had on display was made from two pieces of silicon on the package: one eight-core 7nm chiplet made at TSMC, and a 14nm input/output chiplet with the dual memory controllers and the PCIe lanes, made at GlobalFoundries.

The company did state that it is the world’s first 7nm gaming CPU, and will also be the world’s first mainstream CPU to support PCIe 4.0 x16. At this time the company is not commenting on if the 3rd Gen is going to have a maximum of eight cores, or if this represents the best processor of the whole family.

Because the processor is still far away from launch, frequencies are not being finalized yet. However, the processor is for the AM4 socket, given that AMD has previously said that it intends to keep backwards compatibility for several generations. That will mean that this CPU will work in current 300 and 400-series AMD motherboards.

What this means for PCIe 4.0 is actually fairly simple. We expect there to be a new line of motherboards presumably something like X570 that will be PCIe 4.0 compatible, for any new PCIe 4.0 graphics cards that will be coming to market. One of the differences with PCIe 4.0 is that it can only handle PCB traces up to 7 inches before needing a redriver/retimer, so these extra ICs are needed for ports lower down the board. But, the first PCIe slot on most motherboards is in that limit, so it would appear that a lot of current 300 and 400 series motherboards, assuming the traces adhere to signal integrity specifications, could have their first PCIe slot rated at PCIe 4.0 with new firmware.

Going For Die Size

As we can see on the die shot above, the 8-core chiplet is smaller than the IO-die, similar to the 8+1 chiplet design on EPYC. The IO-die is not exactly one quarter of the EPYC IO-die, as I predicted might be the case back the Rome server processor announcement launch, but it is actually somewhere between one quarter and one half.

Doing some measurements on our imagery of the processor, and knowing that an AM4 processor is 40mm square, we measure the chiplet to be 10.53 x 7.67 mm = 80.80 mm2, whereas the IO die is 13.16mm x 9.32 mm = 122.63 mm2.

+15% Performance Generation on Generation, Minimum.

During the keynote, AMD showed some performance numbers using the new Ryzen 3rd Generation (Matisse) processor. The test in question was Cinebench R15.

Our internal numbers show the 2nd Generation Ryzen 7 2700X scores 1754.

This new 3rd Generation Ryzen processor scored 2023.

This would mean that at current non-final clocks, the new parts give a 15.3% increase in performance generation on generation. Cinebench is an idealized situation for AMD, but this is not at final clocks either. It will depend on the workload, but this is an interesting data point to have.

Identical Performance to the Core i9-9900K, Minimum.

Our internal benchmarks show the 9900K with a score of 2032.

The 8-core AMD processor scored 2023, and the Intel Core i9-9900K scored 2042.  

Both systems were running on strong air cooling, and we were told that the Core i9-9900K was allowed to run at its standard frequencies on an ASUS motherboard. The AMD chip, by contrast, was not running at final clocks. AMD said that both systems had identical power supplies, DRAM, SSDs, operating systems, patches, and both with a Vega 64 graphics card.

At Just Over Half The Power…?!

Also, in that same test, it showed the system level power. This includes the motherboard, DRAM, SSD, and so on. As the systems were supposedly identical, this makes the comparison CPU only. The Intel system, during Cinebench, ran at 180W. This result is in line with what we’ve seen on our systems, and sounds correct. The AMD system on the other hand was running at 130-132W.

If we take a look at our average system idle power in our own reviews which is around 55W, this would make the Intel CPU around 125W, whereas the AMD CPU would be around 75W.

AnandTech System Power Idle Power* Chip Power CB 15 MT Score

All-Core Frequency
AMD Zen 2 130W 55W 75W 2023 2057 ?
Intel i9-9900K 180W 55W 125W 2042 2040 4.7 GHz
*A rough estimate given our previous review testing

This suggests that AMD’s new processors with the same amount of cores are offering performance parity in select benchmarks to Intel’s highest performing mainstream processor, while consuming a lot less power. Almost half as much power.

That is a powerful statement. (ed: pun not intended)

How has AMD done this? IPC or Frequency?

We know a few things about the new Zen 2 microarchitecture. We know it has an improved branch predictor unit, and improved prefetcher, better micro-op cache management, a larger micro-op cache, increased dispatch bandwidth, increased retire bandwidth, native support for 256-bit floating point math, double size FMA units, and double size load-store units. These last three parts are key elements to an FP-heavy benchmark like Cinebench, and work a lot in AMD’s favor.

As the Intel CPU was allowed to run as standard, even on the ASUS board, it should reach around 4.7 GHz on an all-core turbo. AMD’s frequencies on the processor were unknown; but also they are not final and we ‘should expect more’. Well, if the processor was only running at 75W, and they can push it another 20-30W, then there’s going to be more frequency and more performance to be had.

The one thing we don’t know is how well TSMC’s 7nm performs with respect to voltage and frequency. The only chips that currently exist on the process are smartphone chips that are under 3 GHz. There is no comparable metric – one would assume that in order to be competitive with the Core i9-9900K, the processor would have to match the all-core frequency (4.7 GHz) if it was at the same IPC.

If the CPU can't match IPC or frequency, then three things are possible:

  1. If the TSMC process can’t go that high on frequency, then AMD is ahead of Intel on IPC, which is a massive change in the ranks of modern x86 hardware.
  2. If the TSMC process can clock above 5.0 GHz, AND there is room to spare in the power budget to go even higher, then it’s going to be really funny seeing these processors complete.
  3. AMD's Hyperthreading for software such as CineBench is out of this world.

TL;DR = AMD’s 3rd Gen Ryzen Processors Are Another Step Up

When speaking with AMD, their representative said that there will be more information to follow as we get closer to launch. They’re happy for users to discuss whether it is IPC or frequency that is making AMD the winner here, and they’ll disclose more closer to the time.

Ian, I Thought You Predicted Two Chiplets?

Naturally, I assumed that AMD would be presenting a Ryzen-3000 series desktop processor with sixteen cores. For me, and a lot of others, felt like a natural progression, but here we are today with AMD only mentioning an eight core chip.

I predicted wrong, and I've lost my money (ed: in Las Vegas no less). But if we look at the processor, there’s still room for a surprise.

There’s room for a little something extra in there. There’s not much room for a little something extra, but I’m sure if AMD wanted to, there’s just enough space for another CPU chiplet (or a GPU chiplet) on this package. The question would then be around frequency and power, which are both valid.

There's also the question of lower core count processors and the cheaper end of the market. This processor uses silicon from TSMC, made in Taiwan, and GlobalFoundries, made in New York, then packaged together. We have heard some discussion from others not in the industry that this makes cheaper processors (sub $100) less feasible. It is entirely possible that AMD might address that market with future GPU. 

What AMD has plans for in the future, I don’t know. I don’t have a crystal ball. But it does look like AMD has some room to grow in the future if they need to.

    It's announcing that there will be a product announcement. At a product announcement, you give the product a name, specifications, availability (and usually pricing). They did not do that, but they did preview one chip that they will be announcing later. Not every "announcement" is the same - yes, she did announce things, but she did not announce Ryzen 3 products specifically, so she made some "pre-product announcement" announcements, hence "pre-announce."
  • KOneJ - Thursday, January 10, 2019 - link

    "later" necessitates a "before". pre (before) announcing the product. This is information being prior (before) announced before the product announcement. sing-electric is correct.

    That IO die, like on the Epyc, is awfully big. I think there's more to it than just 24X PCIe, IF, USB 3.1g2 and a couple SATA ports. Is the memory controller on it? Could there be some L4 cache on it?

    Seriously, the whole Ryzen 1000 line was 192mm^2, made with the same manufacturing process, with 8 cores, and this IO die is 122mm^2. How could the combined IO die and 7nm core die sizes be larger than the original Ryzen die if it contained the exact same features? There has to be more there.
  • PixyMisa - Wednesday, January 9, 2019 - link

    WikiChip puts the size of the CCX at 44mm^2, so that IO die actually looks about the right size for everything else on the Zeppelin die.
  • dgingeri - Wednesday, January 9, 2019 - link

    192mm^2 - 88mm^2 = 104mm^2, so, yeah, perhaps that extra space might be made up for extra IF circuitry for another die to attach.

    Still, the combined die sizes come out to bigger than the Zeppelin die. The old CPU CCXs at 14nm were 88mm^2 total, and this node shrink should reduce the CPU cores about 40% and the cache by about 10%, so I would think the CPU chiplet would be closer to 50-55mm^2, yet it is over 80mm^2.

    I knew something looked too big. I was wrong about the IO die, but not about something being too big. My first thought was perhaps an inclusive L4 cache on the IO die to reduce cache snoop stalls, but that was wrong. Perhaps converting the L3 to an inclusive cache instead of the victim cache function it serves now? Perhaps an increase in cache size? I think increasing the L3 cache size while keeping it a victim cache would be counter productive. Anyone have any ideas on what they'd do that would increase the CPU chiplet size?

    "AMD is committing itself to 7nm as the future process note that will drive the company's innovations starting in 2019"
    Note? you mean NODE?
  • Darcey R. Epperly - Wednesday, January 9, 2019 - link

    Availability Q2 or Q3. Isn't this when Intel 10 nm Sunny Cove will be around too? If AMD catches up to 9900K then Intel will increase the performance again. Is it ok to say, AMD Zen 2 comes a bit too late?
  • dgingeri - Thursday, January 10, 2019 - link

    Intel was caught unaware when the initial Ryzen came out. They had to rush to get the 8700k out. The 9900k is at the limits of the ring bus that keeps the processor operating, and operates above it's specced TDP. I seriously doubt Intel could do anything to extend the performance of what they currently have out. They need to get new tech out to show AMD more competition, and that isn't coming for at least another year. Sunny Cove isn't expected to see the light of day until Q2 or Q3 of 2020, not 2019.

    In the mean time, AMD is not only competing, but doing so at much lower prices. Intel is having a much harder time of this than most people think.
  • RSAUser - Friday, January 11, 2019 - link

    As dgingeri said, Intel is in a bit of a predicament currently, their architecture is at its limit and the new architecture is only expected around 2020. A die shrink could have helped them achieve parity/similar performance to AMD, but 10nm is still delayed.

    They'll probably have 7nm out before/same time as 10nm in 2020/2021.
  • TheJian - Wednesday, January 9, 2019 - link

    I just hope this is $400 or so, or even closer to Intel $478 if it is just as good. NO DISCOUNTS. It's time to make NET INCOME. Then add a 2nd chiplet and release 12/16 cores ASAP to slap those ON TOP of Intel. Don't charge $299 for this unless it really sucks perf wise. It seems it's directly competitive with Intel 9900, so PRICE it like that! Quit passing up opportunities to make INCOME, by attempting to either get market (with no margin) or be your customer's friend. Charge what your chips are WORTH! In the last 4yrs they've lost 1.2B+ (~400mil losses for 3yrs, 2017 finally made ~40mil NET INCOME). 2018 looks like a few hundred mil for the year, and we'll know that in a few weeks (29th or so Jan). If you want to FINALLY make money for 2yrs straight, don't give a dang discount on a chip that runs like Intel's $478 chip. Price it at $450. It is NOT your job as a company to GIVE away chips with every launch at major discounts.

    IE see rumored Navi10 pricing, $249 for a GTX 1080/1070ti perf...Uh, should be $350-400 then min probably. But $249, well, I'd fire management for this price. They won't make money. Not sure if they'll make a dime on $699 card either, as 16GB HBM will kill the card most likely as it has done to EVERY consumer card they've put it on (besides holding up production on top). It should have been 16GB GDDR6 or GDDR5x. There is a reason NV made billions going GDDR5x instead of HBM/HBM2. There is no need for HBM in current cards as 2080ti shows. GDDR6 fine. They keep making the same dumb decisions (HBM, kill production+kill NET income). AMD should not be producing a consumer gpu with HBM (1/2 or 3). It gets you nothing but PROBLEMS (cost or production issues) and kills sales or profit. Charge what you're worth, but quit adding crap to your products that kill their INCOME or ability to sell them (hbm production issues constantly killing launches).
