Intel's motherboard partners such as ASUS are offering new H510 motherboards for the LGA 1200 Desktop CPUs. What's surprising about these motherboards is that they actually make use of a chipset that's almost 3 years old.
ASUS Reuses H470 Chipset To Power New H510 Motherboards For Intel LGA 1200 CPUs
A recent tweet by Momomo_US reveals that ASUS is preparing four H510 motherboards that will be targeted at entry-level PCs. These motherboards include the PRIME H510M-A R2.0-CSM, the PRIME H510M-E R2.0-CSM, the H510M-E R2.0 & the PRIME H510M-A R2.0. You can find these motherboards at the following links:
All four motherboards are basic with an mATX design, and support for PCIe 4.0 hardware and featuring a range of heatsinks. The H510M-A series comes with heatsinks for the VRMs and the M.2 slot.
The most interesting aspect of these ASUS H510 motherboards is that they were officially launched with the Intel 11th Gen Rocket Lake CPUs. Intel did offer compatibility between the Comet Lake and Rocket Lake CPUs and both could be used on the same motherboard platform. However, there's even more to the story.
While the motherboard is labeled as the H510, the actual chipset on these motherboards is the H470 which goes back to the Comet Lake generation. It is possible that the H470 chipset being used by the H510 motherboards has some features disabled to make it appear on the same level as the H510 series. H510 PCH is an entry-level chipset while H470 was a higher-end SKU.
The reason why ASUS is making motherboards this way is likely to do with excess inventories of older chipset. Since consumers may not want to buy older products, ASUS is giving the old PCH a second life by offering them a more modern platform. Reusing older chipsets also mean that manufacturers can reduce the cost of their new products by a huge margin but it remains to be seen if those cost advantages will be given to the consumers too.
