AMD revealed the Ryzen 3 3100/3300 and B550 chipsets on April 21st. The Ryzen 3 3100/3300 will be released on May 21, and the B550-equipped motherboard will be on or after June 16, but a little more detailed material was released before this, so I would like to introduce it.
Ryzen 3 3100/3300
The first thing about Ryzen 3 has two variants, both have 4 cores and 8 threads, and L3 is 16MB. TDP 65W power supply is also universal. As mentioned above, the only difference is the operating frequency and price. The domestic price of Ryzen 3 3300X is 120 USD, and for Ryzen 3 3100 is MSRP is 99 USD. By the way, product positioning can be found below. The Ryzen 3 3100 announced this time is competing against the Core i3-9100F and the Ryzen 3 3300X against Core i5-9400F, respectively.
What is related to this is that it was announced today that the Ryzen 5 1600AF would be released domestically. AMD has introduced this Ryzen 5 1600AF as the so-called inventory disposal of 12 nm process products, and if it issues a 7 nm process, Ryzen 3 3100 at a price below this, nobody will buy Ryzen 5 1600 AF Isn’t it? That’s my guess (or preferably, the inferior kind). I know that the price strategy is rather tricky, but it cannot be denied that the attractiveness of the Ryzen 3 3100 has diminished as a result.
Well, first, the result of comparing Ryzen 3 3100 with the previous generation Ryzen 3 2300X and Core i3-9100 is the photo below. It doesn’t feel like it’s big enough to drain water, but it’s understandable that it feels like they can fight in equal terms.
Next is the Ryzen 3 3300X, but an exciting story As you know, Ryzen 3000 series consists of CCD (CPU Chiplet) and CIoD (I / O Chiplet) with two CCXs. However, in the case of Ryzen 3, it has 4 cores,
- Take advantage of 2 CCXs, 2 cores each
- Make one CCX full of 4 cores and kill the other
There are two patterns processor works on; The major performance advantage here is that only one CCX can be used. This is because the communication between CCXs goes through CIoD once, so the latency is large. This is the same for sharing L3, and when accessing L3 of CCX on the other side from one CCX, it will be via CIoD so that it will be slower & the bandwidth will be low (Infinity Fabric between CCD and CIoD Bandwidth becomes a bottleneck). Therefore, in Ryzen 3 3300X, by taking a 4 + 0 configuration that makes full use of one CCX with 4 cores, the performance is improved compared to Ryzen 3 3100 (or rather, Ryzen 3 3300X is Native performance, Ryzen 3 3100 is (Slightly shackled).
So what is the performance of the higher-performer Ryzen 3 3300X? This is explained in the slides below. The competition is Core i5-9400F.
By the way, the package is the same thin type as before, and Wraith Stealth is included.
The B550 Chipset was announced along with this. As you can see from the model number, it is a chipset for the middle range, but Dual GPU support and PCIe Gen4 / Gen3 support are newly added (Photo 12). Here is a summary of the main differences (Photo 13). in short,
PCIe x16 from CPU supports Gen4
PCIe x4 from CPU also supports Gen4
PCIe from Chipset supports PCIe Gen3
It became a form. The NVMe M.2 SSD for boot uses PCIe x4 lanes coming out of the CPU so that you can fully utilize the advantages of PCIe Gen4 compatible products, whose lineup is increasing recently. Here (Photo 14) is the actual configuration. The number of I / F itself is almost the same as that of B450, but it may be considered that B550, which has been partially speeded up & Dual GPU support, was added.
However, it should be noted that the Ryzen B550 is made only for products manufactured in the 7nm process, not the Ryzen 3000G series or Ryzen 2000 series manufactured in the 12nm process. In other words, it will not work on old CPUs, so be careful. Already more than 60 products are currently being designed and will be flooding the market with the announcement of June 16th.
