PC Tech AMD Ryzen 3rd Gen 'Matisse' Coming Mid 2019; Core i9-9900K, Minimum Performance ~50% the power; Room for 16 cores/32 threads

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.

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.

While the chip showed was only 8 cores/16 thread, there is clearly room for another chiplet to make it 16 cores/32 threads. They could also add an integrated Vega GPU.

Mmm, if they can get the overall single core performance close to Intel's then this will be my next upgrade, assuming they will price these aggressively like they have been with Ryzen so far.

How will it compete in gaming?  Have they got the single core frequencies up?

We don’t know, although this is a high performance node. From anandtech:

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:

 

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.

 

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.

 

AMD's Hyperthreading for software such as CineBench is out of this world.

so does this line up with those rumored specs from last month? 

It doesn't confirm frequencies or pricing. What it does almost confirm is it appears that AMD will have some 12 and 16 core ryzens at some point. It may not be in the first wave of releases.
