Intel’s Biggest Battlemage Chip Revealed: 27.7 Billion Transistors, Workstation Only
Intel has quietly disclosed the full physical specifications for its largest Battlemage graphics chip, the BMG-G31. According to PC Games Hardware, the chip contains 27.7 billion transistors on a 368 mm² die, manufactured by TSMC on its 5nm process node (N5). The information comes as Intel launches the Arc Pro B70 and Arc Pro B65 workstation cards, which are the first products to use this silicon.
The BMG-G31 is substantially larger than the BMG-G21 chip found in the Arc B580 and B570 gaming cards, which PCGH lists at 19.6 billion transistors and 272 mm². However, when compared to current GPUs from AMD and NVIDIA, Intel’s chip is an interesting study in trade-offs.
How I2t Compares to AMD and NVIDIA
Despite being roughly the same physical size as AMD’s Navi 48 (357 mm²) and NVIDIA’s GB203 (378 mm²), the BMG-G31 packs significantly fewer transistors because it uses a less dense manufacturing node. AMD and NVIDIA use TSMC’s more advanced N4P process, which offers higher transistor density.
- Intel BMG-G31: 27.7B transistors, 368 mm² (TSMC N5)
- NVIDIA GB203: 45.6B transistors, 378 mm² (TSMC N4P)
- AMD Navi 48: 53.9B transistors, 357 mm² (TSMC N4P)
The numbers show that Intel’s largest Battlemage chip has roughly 39% fewer transistors than NVIDIA’s GB203 and nearly 49% fewer than AMD’s Navi 48, despite taking up similar die area.
Specs and Performance
The Arc Pro B70 workstation card features 32 Xe2-HPG cores, 256 XMX engines, 32 ray tracing units, 32GB of memory, a 256-bit interface, 608 GB/s bandwidth, and native PCIe 5.0 x16. A cut-down variant, the Arc Pro B65, uses the same chip with fewer active cores but retains the 256-bit memory bus (despite Intel incorrectly labeling it as 192-bit in some materials).
According to Intel, the Pro B70 is roughly 45% faster than the Pro B60 in gaming workloads. That would still leave it uncompetitive with the high-end NVIDIA and AMD gaming GPUs mentioned above, but pricing could make it interesting in the professional segment.
No Gaming Variant Planned
For gamers hoping to see a “Big Battlemage” gaming card, the news is disappointing. Intel has confirmed it is not planning a gaming variant of BMG-G31 at this time. The chip is targeted exclusively at workstation and professional markets through the Arc Pro series.
That means the gaming Battlemage lineup remains limited to the BMG-G21-based Arc B580 and B570, which target the entry-level and mid-range segments. Enthusiasts looking for a high-performance Intel gaming GPU will have to wait for the next architecture—likely Celestial—to see if Intel returns to the high-end gaming market.

Intel’s BMG-G31 is an interesting engineering effort: a large chip on a mature node that prioritizes workstation features and memory capacity over raw transistor count. But without a gaming SKU, its impact on the consumer GPU market is effectively zero. For now, the “Big Battlemage” remains a professional product.
