All the news of the amd b450 chipset

Finally the day has come to launch the new AM4 motherboards with the B450 chipset, it is the new mid-range chipset from the AMD platform, which comes to improve the characteristics of its predecessor, the B350, while offering a most interesting proposal when assembling a PC based on an AMD Ryzen processor.

The importance of the B450 chipset for Ryzen's success

The B450 chipset comes as a tune-up from the previous B350, to enhance the features offered to users on mid-range motherboards. The new chipset is compatible with all processors for the AMD platform, including first- and second-generation AMD Ryzen, Raven Ridge APUs, and the now out-of-date Bristol Ridge that build on the previous Bulldozer architecture.

All of these processors are also compatible with the B350 chipset, although you will need a BIOS update on your motherboard. The difference is that the B450 motherboards already come from the factory with support for all these processors, so you will not have to update anything. Both chipsets will also be compatible with the third generation Ryzen processors, requiring a BIOS update in all cases. The chipsets of the AM4 platform have the function of complementing the basic capabilities of the platform, which are included in the processor itself.

The following table summarizes the characteristics of all chipsets for the AM4 platform, with this we can understand the great importance of the B450 for the success of this platform.

Chipset	X470	X370	B450	B350	A320
USB 3.1 Gen 2	two	two	two	two	one
USB 3.1 Gen 1	6	6	two	two	two
USB 2.0	6	6	6	6	6
SATA III	4	4	two	two	two
PCIe 3.0	two	two	one	one	one
PCIe 2.0	8	8	6	6	4
GPU	1 × 16/2 × 8	1 × 16/2 × 8	1 × 16	1 × 16	1 × 16
Overclocking	Yes	Yes	Yes	Yes	Do not
XFR2	Yes	Yes	Yes	Yes	Yes
Precision Boost Overdrive	Yes	Do not	Yes	Do not	Do not
Store MI	Yes	Do not	Yes	Do not	Do not

As we can see from the table above, the B450 chipset hardly differs from its older brother, the X370 in some PCIe connections and SATA III ports. The B450 chipset maintains the ability to overclock and all the important Ryzen technologies, this makes it the best alternative to build a team with excellent characteristics, but a tighter final price. B450 is the recommended chipset for all AMD processor users who do not require a large number of PCIe lanes and SATA III ports.

AMD Store MI

The B450 chipset does not come with many new features, the only ones being Precision Boost Overdrive and Store MI technologies. We review these two important technologies that come from the hand of the new Ryzen 2000 processors.

StoreMI is a technology that comes to solve the problems of lack of speed in the storage of many PCs. Mechanical hard drives are very slow, although their price for each GB of capacity is very low, making it possible for users to access large doses of storage without spending a lot of money. In contrast, SSDs are very fast, but their price per GB is very high.

This creates a situation where it is very common for users to combine a high capacity HDD together with a low capacity SSD. StoreMI is a technology that allows combining both HDDs and SSDs in a single memory pool, which will have the advantages of both technologies. StoreMI uses the SSD as a cache to speed up the mechanical hard drive, allowing you to have a large amount of high-speed storage.

Thanks to this, you can have a large number of games installed on your PC, and all of them will load very quickly, almost as much as if they were installed on an SSD. You can also allocate up to 2GB of RAM as a cache to further improve speed. With StoreMI hard drives work up to 9.8 times faster, something that will come in handy if you need a large amount of storage space. StoreMI has a free version that can combine an SSD of up to 256GB with any HDD, you can also create a 2GB DRAM cache to further speed up the system.

Precision Boost Overdrive are the only novelties

Precision Boost Overdrive is one of the best technologies AMD has created. It is an automatic overclocking mode, which allows you to get the most out of the processor without the user having to do anything. Precision Boost Overdrive is a new much more linear frequency boost algorithm than the first version of this technology, allowing AMD Ryzen 2000 processors to run their cores at speeds above base speed, even if multiple cores are used at the time.

It is a new algorithm that takes into account in a much more efficient way all the factors that affect the consumption and temperature of a processor, such as the number of cores in use and their load, in this way it is possible to achieve higher frequencies, even if all processor cores are in use. This technology is especially relevant in applications that are very sensitive to operating frequency, for example video games.
