What is a Chipset?

A chipset is essentially the brain of the motherboard itself. Think of the motherboard as the neural system that connects the different appendages and organs of the body. The chipset acts as the brain of the entire neural system, as it commands and controls the features of the motherboard.

chipset b660 vs h670

The motherboard’s chipset is the traffic controller that directs the motherboard’s functions and dictates the various features that are available to the motherboard. Essentially, it is the chipset that decides the compatibility of the motherboard with any CPU, even if the CPU physically fits in the socket.

Intel is pretty straightforward with its chipset models scheme for desktop processors. The top-tier, flagship chipset with all the bells and whistles is denoted by the letter Z, such as Z690 for the Intel 12th Generation CPUs.

The mid-range and budget chipsets are denoted by the letters H and B respectively, such as H670 and B660 for the 12th Generation Intel processors.

Differences Between B660 VS H670

Among the Intel 600 series motherboard lineup that accompanies the 12th Generation Alder Lake processors, the H670, B660, and H610 Intel chipsets are considered the budget options. The most premium platform is Z690, followed closely by H670, B660, and H610 in that order.

Both the B660 and H670 chipsets support LGA 1700 socket, and the following Intel 12th Generation CPUs:

12900KS, 12900K, 12900KF, 12900, 12900F, 12900T, 12700K, 12700KF, 12700F, 12600K, 12600KF, 12600, 12600T, 12500T, 12490F, 12400, 12400F, 12400T, 12300, 12300T, 12100, 12100F, 12100T, Pentium Gold G7400, G7400T, Celeron G6900, G6900T

The hierarchy of the chipsets is established due to the various features that are present or absent on each chipset. If you are deciding between the two budget platforms of B660 and H670, then you need to keep in mind the following differences.

CPU Overclocking SupportNoNo
CPU PCI Express 5.0 Lanes1×16 / 2×81×16
Chipset PCI Express 4.0 Lanes126
Chipset PCI Express 3.0 Lanes128
DMI 4.0 Lanesx8x4
Max Number of SATA 6.0 GB/s84
Max Number of USB Ports1412

PCIe Lanes

Every chipset has a different configuration of PCI Express lanes, and that has a big effect on the number and speed of devices you can connect to the motherboard.

ChipsetPCI-E Lanes

All 12th Gen desktop chipsets support both PCIe 4.0 and PCIe 5.0 technically, although only PCIe 3.0 and PCIe 4.0 lanes are distributed across the motherboard to various storage devices. The PCIe 5.0 support is limited to only the top full-sized x16 PCIe slot in both B660 and H670 motherboards.

PCIe 5.0 was recently announced as the newest version of the PCIe standard. PCIe 5.0 doubles the data transfer rate of PCIe 4.0, making it the fastest version of PCIe yet. PCIe 5.0 is also backward compatible with older versions of PCIe, so it can be used in conjunction with existing hardware.

One of the benefits of PCIe 5.0 is that it provides more headroom for future products. PCIe 5.0 will start to appear in new devices in 2020, and it is expected to become the new standard for high-end PCs and servers. Both B660 and H670 motherboards support this standard, which is really important.

The differences start when you compare the number of total PCI Express lanes available directly from the chipset. On H670 motherboards, you get a total of 24 lanes from the chipset, while in B660 motherboards you only get 14 lanes from the chipset.

This is quite a substantial difference and it makes the H670 chipset superior, at least in terms of PCIe distribution. H670 is also quite close to the flagship Z690 chipset in terms of PCIe lanes (24 vs 28).

Storage and SSDs

Another key difference between the B660 and H670 chipsets can be realized when comparing the storage capabilities of both the motherboards. This is a continuation of the differences between the PCIe configurations of the two platforms.

Both the H670 and B660 motherboards support PCIe 4.0 functionality when it comes to storage devices such as NVMe SSDs. However, the number of PCIe 4.0 lanes available to H670 is more than the number available to B660 motherboards.


This means that manufacturers can install more PCIe 4.0 M.2 slots on H670 motherboards, as compared to B660 motherboards. You can also see this difference in the number of total M.2 slots, as H670 motherboards will often have more M.2 slots in total than B660 motherboards.

You can also see this difference in terms of SATA-based drives. B660 motherboards support a maximum of 4 SATA ports, so you cannot expand beyond that number in terms of your SATA drives. On the other hand, H670 and Z690 motherboards give you support for 8 SATA ports.

USB Ports and I/O

Both B660 and H670 are quite similar when it comes to the rear I/O. For instance, both chipsets have two USB 3.2 Gen 2 x2 20Gbps ports and four USB 3.2 Gen 2 x2 10Gbps ports. However, there are still some differences.


USB FeaturesH670B660Max Number of USB Ports1412Max USB 3.2 Gen 2×2 Ports (20Gbps)22Max USB 3.2 Gen 2×2 Ports (10Gbps)44Max USB 3.2 Gen 1×1 Ports (5Gbps)86Max USB 2.0 Ports1412

When it comes to the legacy ports, the H670 chipset starts to increase the gap. You get a maximum of eight USB 3.2 Gen 1 x1 ports, while you only get 6 of these ports on the B660 platform.

Even further down the stack, you can get a maximum of 14 USB 2.0 ports on the H670 platform, but the B660 chipset only offers a maximum of 12 USB 2.0 ports.

In any case, the number and type of USB ports are going to differ depending on the manufacturer of the board as well as the price point.

More expensive motherboards on either chipset can expect to receive more of the high-speed USB ports, while budget options and mini ITX motherboards will receive fewer ports on the rear I/O.

Support Memory Overclocking

Thankfully, Intel has reversed the bone-headed decision of restricting memory overclocking on budget chipsets and has provided support for memory overclocking on B660 and H670 platforms.

built pc

This means that you can overclock your memory on any 12th Gen chipset, except H610. This includes both X.M.P tuning and manual memory overclocking, both of which are great ways to improve your gaming performance if you have the time and skill.

Support CPU Overclocking

The B660 vs H670 motherboards do not support CPU overclocking. Intel has only restricted CPU overclocking support to the flagship Z-series motherboards for a while now, and the same trend continues in this generation.

If you want to overclock your K-series unlocked CPU, then be sure to buy a Z690 motherboard to go along with it as it is the only chipset that supports CPU overclocking.


Of course, one of the most important factors in the purchasing process of a motherboard is the price tag. Since the H670 chipset offers more features, the H670 motherboards are more expensive in general than the B660 motherboards on the market.

pricing for motherboards

However, H670 motherboards are also quite rare and that dictates the pricing as well. In a normal market, you can find H670 motherboards starting around the $200 mark, while B660 motherboards can be found cheaper at around the $170-180 mark too.

More important than the price tag is the price-to-performance ratio. It is no use buying a super cheap motherboard with a poor VRM design and no features when a much better motherboard can be had for an additional $10-20.

Despite being a bit more expensive, H670 motherboards can sometimes offer a better bang for your buck, thanks to the extra features and better build quality of those motherboards as compared to B660 options.
