Intel’s next-generation Battlemage graphics cards won’t be much of an upgrade over existing A700-series Alchemist GPUs. According to RedGamingTech, the overall core count will remain unchanged gen-over-gen. Consequently, the Arc B770 will have the same core count (4096) as the A770. With Battlemage, Intel is doubling the width of the Vector Engine (previously, Execution Engine) from 8 ALUs to 16. However, this will be offset by the decrease in the VE/EU count per Xe Core, from 16 on Alchemist to 8 on Battlemage.
In conclusion, the GPU cores will be more closely knit across fewer but wider Vector Engines. The Arc B770 will be paired with a 16GB memory buffer (GDDR6/GDDR6X) via a 256-bit bus (like the A770). The GPU core clock will be in the 2GHz region, while the L2 cache will be increased from to 32 MB. The process node has been upgraded to TSMC’s N5P (5nm) from N6 (6nm) on Alchemist.
The midrange G21 Battlemage die will consist of 20 Xe cores (2560 shaders) paired with a 12GB memory buffer across a 192-bit bus. The GPU (2GHz) and memory clocks (20Gbps) are expected to be similar to the larger G31 GPU. An L2 cache of 16MB and 8x PCIe Gen 5 lanes are among the leaked details.
Intel’s Arc Battlemage GPUs were expected to launch in the second half of 2024. However, more recent reports claim that the release has been pushed to 2025 to avoid a confrontation with the RTX 50 or AMD’s RDNA 4 lineup.
