Get ready, tech enthusiasts, because Intel's next-generation graphics card, the Arc B770, is rumored to be a real power-guzzler! Recent leaks from a shipping manifest suggest this new GPU could have a Thermal Design Power (TDP) of a whopping 300W. But what does this mean for gamers and PC builders? Let's dive in.
This news comes as anticipation builds for Intel's 'Battlemage' GPU, the successor to their current Arc series. The leaks, spotted by @x86deadandback, reveal a part number (N38341-001) associated with the upcoming GPU. While the exact model isn't confirmed, the context strongly suggests it's the Arc B770, especially considering the Arc B580 has a different part number (B19826).
The most striking detail is the estimated 300W TDP. For those unfamiliar, TDP indicates the maximum power the graphics card will draw. This is significantly higher than the Arc B580's 190W and even the current Arc A770's 225W. This increase suggests the B770 will be a high-performance card, potentially competing with the top-tier offerings from NVIDIA and AMD.
This also hints at the complexity of the BMG-G31 chip that powers the B770. The BMG-G31 is expected to be a larger die than the BMG-G21, potentially featuring 32 Xe2 cores (or 4096 Shaders). It is also rumored to have a 256-bit memory bus with 16 GB of GDDR6 VRAM, boasting a memory speed of 19 Gbps, which translates to a memory bandwidth of 608 GB/s.
But here's where it gets controversial... This high power consumption could mean the B770 will require a more robust cooling system and a more powerful power supply unit (PSU) in your PC. This could impact the overall cost and complexity of building or upgrading a system. Also, the B770 is expected to beat the RTX 5060 Ti and the RX 9060 XT 16 GB cards for a noticeably lower price, but it remains to be seen if Intel can succeed in the discrete GPU market.
Here's a quick comparison of the rumored specs:
| Graphics Card Variant | Arc B7XX | Arc B580 | Arc A770 |
| :------------------- | :----------------- | :----------------- | :----------------- |
