Five CPUs, 12 cores for $ 499, up to 4.6 GHz, PCIe 4.0, 7/7 available



AMD Managing Director Lisa Su today announced at Computex how many processors will bring their new Zen 2 chip-based microarchitecture to market. Among other things, AMD introduces the new product line Ryzen 9, which is used for the 12 core processor Ryzen 9 3900X and which works with 4.6 GHz boost. All five processors will be PCIe 4.0 compliant, and while they are accompanied by the introduction of the new X570 chipset, they still use the same AM4 socket, allowing some AMD 300 and 400 series motherboards to continue to be used. We have all the details in view.

Many people have been studying details of the next generation of the AMD Ryzen platform for several months since AMD teased the Matisse Ryzen 3000 design at CES in January. Most of this information is released today with the processors Ryzen 9, Ryzen 7 and Ryzen 5. All of these processors will be officially launched on July 7 (7/7). This correlates with the fact that the core components of these products are based on TSMC's 7nm process. This is technically a Sunday, but AMD does not mind. In fact, this means that users may receive them by e-mail the following Monday.

Before we go into functions, we go straight to the CPU list, since most of you are here for it.

The new flagship: Ryzen 9 3900X

The Ryzen 3000 series introduces a new AMD product stage: Ryzen 9. In this case, the Ryzen 9 3900X is the first from AMD mainstream desktop 12-core processor. The processor is the only one in the group that uses two chips in a 6 + 6 configuration. The 3900X will have a 3.8GHz base frequency and 4.6GHz turbo frequency, and will feature 6MB L2 cache and 64MB L3 cache. This confirms that each chiplet has 32 MB of L3 cache, which doubles the result of the first generation of the Zen microarchitecture. This CPU has a TDP of 105 W, which is usually a good measure of the power consumption of all cores for AMD processors, and is activated with 24 PCIe 4.0 lanes (16 for the GPU, 4 for the memory, 4 for the chipset) ,

The Ryzen 9 3900X will have a proposal e-tail price of $ 499, and it will come with a radiator (more details in the coming weeks). AMD compared this processor in its presentations with Intel's 12-core HEDT processor, the Core i9-9920X, which has an MSRP of $ 1,199 and is not equipped with a cooler.

In this comparison, AMD provided a comparison of the Cinebench R20 performance data for the two processors (note that we can not confirm these results at this time). AMD claims that the 3900X outperforms the 9920X + 14% in single-threaded performance, and gains 6% in multi-threaded performance, despite having a lower TDP (165W vs. 105W).

The Ryzen 9 3900X is the new mainstream desktop flagship, though AMD clearly has enough headroom for this design to accommodate a full 16 cores. Most users expect this to happen in the future. So it will be interesting to see if AMD will play this card strategically.

Mainstream Madness: Ryzen 7 at 65W

For the Ryzen 7 formation, AMD is Keep this for the 8-core versions. These CPUs contain only a single chiplet and no dummy chiplet. Of the two CPUs in this segment, the one that gets a big shock from us is the cheaper model.

The Ryzen 7 3700X is a 16-threaded eight-core CPU with a base frequency of 3.6 GHz and a 4.4 GHz turbo frequency. It has 4MB of L2 and 36MB of L3 (half of the L3 compared to Ryzen 9, since it has only one chip), but the amazing thing is that this chip has a TDP of only 65W. Only on paper does it look like this processor is one of the most efficient x86 desktop processors ever made. This is probably the CPU configuration that AMD used in its Cinebench R20 demo at CES, where it showed R20-equivalent multithreaded performance with 40% less system performance. And the price for all this performance? Only $ 329. When I put on my reviewer hat and look at these specifications at a high level, the Ryzen 7 3700X promises to be the mainstream chip of choice for a significant number of high-performance PCs this year.

As with the Ryzen 9 3900X, AMD has also done a Cinebench comparison with the Intel mainstream Core i7-9700K on the 8-core Ryzen 3700X. Here they reached the multithreaded test of the R20 4806, the 9700K 3726.

The other CPU in this bracket is the Ryzen 7 3800X. This is the direct upgrade of the current Ryzen 7 2700X with eight cores and sixteen threads, a fundamental frequency of 3.9 GHz and a boost frequency of 4.5 GHz. It does not seem particularly impressive compared to the 3700X with its larger TDP of 105 W and only a few hundred MHz more on the fundamental frequency, but as we've already seen in the second and Gen Ryzen, this extra TDP headroom helps usually with technologies like XFR that manage the boost frequencies. AMD has not said anything new about how XFR or Precision Boost work in the new generation. We have to wait for the publication of this information. However, the additional frequency and the additional TDP cost an additional $ 70: The Ryzen 7 3800X costs $ 399.

Budget Builds: Ryzen 5 with Six Cores

Not mentioned in the keynote, but discussed in the press AMD also released information on the new Ryzen 5 processors.

These are still very competitive – users can now buy a 6-core processor for under $ 200. The processor frequencies depend on the position in the stack and the pricing. Both CPUs support the same technologies (PCIe 4.0, etc.) as the larger chips. These chips still use a single chiplet, not a dual-chiplet design.

Performance Figures

AMD provided some performance numbers to compare AMD with Intel CPUs. All of these tests use Cinebench R20. This is a floating-point rendering test on which AMD is already achieving good results. However, there are no specific optimizations for each CPU here.

Through direct chip-to-chip comparisons, AMD's single-thread performance over Intel was + 1%. It should be noted that something like the Ryzen 7 3800X, which charges to 4.5 GHz, is compared to an Intel CPU that charges to 5.0 GHz. That would put IPC firmly in the hands of AMD in this test. Multi-Threading results are a similar scenario, although the difference in bias tends to decrease the more cores AMD has available, possibly because more cores with a slightly longer memory latency are struggling for memory access compared to Intel.

Compared to Zen 1 and Zen 2, AMD believes that the Ryzen 9 3900X offers + 32% better single-threaded performance than the Ryzen 7 1800X. With an IPC increase of 40-52% from before Zen to Zen 1, another + 32% for single-threaded performance is a good amount, though 32% involve a frequency increase. When we receive the chips, we will make an obvious comparison test to determine the IPC difference. For multithreaded results, AMD + promotes 100% multithreaded performance, which is supported by + 50% more cores, 2x better FP throughput per core, and higher frequencies.

Other features and X570 motherboards

Apart from 7-nm chips and the huge price compared to Intel speak for themselves. AMD promotes a direct IPC increase of + 15% from Zen 1 to Zen 2 due to improvements in microarchitecture and a doubling of cache size on the L3. The CPU has 24 PCIe 4.0 lanes: 16 for the GPU (or other PCIe cards), four for the memory and four for the chipset. The four for storage will probably be connected to the upper M.2 slot. Given that some companies here at Computex are promoting PCIe 4.0 SSDs, we expect more to follow in due course.

The new X570 chipset has 16 lanes, four for upstream connection to the CPU and twelve for downstream connections to other devices. There is some discontinuity here – we've heard from partners that AMD has actually removed four PCIe lanes from chipset design to lower the TDP of the chipset from 15W to 11W. But the full 15W version will appear in the next editions of the high-end desktop (which would suggest that Threadripper is not dead, unlike many reports – we'll ask Lisa Su this later). , We have already released a number of X570 motherboards and expect a total of around 25 new X570 models. It's clear that motherboard manufacturers are now getting serious with AM4 – some of these boards are likely to sell up to $ 600. These manufacturers clearly expect AMD to hit Intel hard, and have designed the motherboards to match the best Intel CPUs.

One piece of information that is not published is the memory support probably DDR4-3200 in one module per channel mode. This is a small bump about 2 and Gen Ryzen, but still a welcome one. It will be interesting to see how the memory controller works on this design to push that frequency. Memory frequency and Infinity Fabric frequency are still linked, so increasing the memory frequency provides additional benefits.

Finally, the release date for all these CPUs will be July 7 . We are waiting for AMD to announce the time frame for sampling, but our goal is to provide a look back at the first day. Suggestions for review are expressly welcome.

We also have access to Dr. Ing. Lisa Su right after today's keynote address and will write down our questions and answers in due course. Stay up to date.
