Intel is reportedly preparing another Battlemage graphics card that will offer the latest PCIe 5.0 interface, supporting 16 PCIe lanes. PCI-SIG adds “ 99CMLN ” with PCIe 5.0 x16 interface to its database: a sign that newer, more powerful Battlemage GPUs are coming
PCI-SIG (Peripheral Component Interconnect Special Interest Group) recently registered a new Intel product in its database with the codename "99CMLN". While this doesn't reveal anything, the table shows that it's one of Intel's Arc Battlemage series products.
Additionally, it is the first graphics card to feature a PCIe 5.0 x16 interface, which is even larger than the one found on the Arc Pro Battlemage GPU. Leaker @KOMACHI_ENSAKA discovered this change in the PCI-SIG list and revealed the date of the addition (May 9, 2025). It is worth noting that two more Intel Arc Battlemage GPUs were added the day before, codenamed "99CGHV" and "99CW89", which may refer to the Arc Pro B60 and B50.
Mainstream Arc Battlemage series GPUs, such as the Arc B570 and B580, ship with the PCIe 4.0 interface, not PCIe 5.0. The Pro Battlemage graphics cards also use the same BMG-G21 chip as the Arc B570 and B580, but they offer the latest PCIe 5.0 interface, even though the number of available PCIe lanes remains the same. Therefore, "99CMLN" may refer to another more powerful Pro Battlemage graphics card, but it may also be a higher-end model of the B580.
Rumors about the Arc B770 have been circulating for a while, but there is no firm news yet. However, Intel has not denied the existence of this GPU, and according to recent reports, it could be released in the coming months. If the Arc B770 is released with a PCIe 5.0 interface, it likely won't impact its performance, as PCIe 4.0 is fast enough to transfer enough data on the lane to eliminate any bottlenecks. But since NVIDIA and AMD have already adopted the Gen 5.0 interface, it's possible Intel will go the same route.
According to some leaks, the Arc B770 could use the BMG-G31 chip and could be powered by 24 to 32 Xe2 cores, as well as 16 GB of GDDR6 memory via a 256-bit memory bus.
