Intel Arc B-Series powered by Xe3 (for gamers too)
An Intel source familiar with company’s plans has shared additional details about the Arc B-Series graphics for Panther Lake chips. Intel has decided to brand its Xe3-based integrated graphics under the B-Series (Battlemage family) for the upcoming Core Ultra 300 processors (Panther Lake). The naming convention is currently unclear.
OneRaichu has provided more information about the B-Series graphics, confirming that the flagship Arc B390 GPU with 12 Xe3 cores will operate at up to 2.5 GHz. This is not the complete picture. Both B390 and B370, previously leaked on Geekbench, are confirmed, along with B380 and B360.
The Arc B380 GPU, featuring 12 Xe3 cores, will be included in a specific Intel Core Ultra 300 CPU designed for gaming handhelds. OneRaichu clearly suggested that is the plan, noting it is listed but lacks a formal name. The leaker also noted that this SKU may not feature full 16 cores, but this would also suggest it would not be as expensive, which is good news for cheaper handhelds.
Apparently this handheld-focused product sits below the Core Ultra 5 series. It is aimed at the mid-range segment with a focus on gaming performance. It could also put pressure on the Ryzen Z2 series (Lunar Lake already competes in this space).
Intel Arc Panther Lake Series GPUs
- Arc B390 ➡️ 12x Xe3C, up to 2.5 GHz For Ultra X7/X9 SKUs
- Arc B380 ➡️ 12x Xe3, up to 2.3 GHz For Gaming Handhelds
- Arc B370 ➡️ 10x Xe3, up to 2.4 GHz For Ultra 5 338
- Arc B360 ➡️ 10x Xe3, up to 2.2 GHz
- Arc ➡️ 4x Xe3, up to 2.45~2.5 GHz
- Arc ➡️ 2x Xe3, up to 2.3 GHz
If OneRaichu’s information is accurate, Intel Panther Lake will have six SKUs, some of which currently lack names. We are trying to keep our Panther Lake spec sheet up to date, so if this SKU is indeed coming, it would be somewhere in the middle of the stack.
