On January 4, 2026, Intel's Arc B770 graphics card appeared in an official GitHub repository alongside existing Arc products. The listing, spotted by leaker Haze2K1, marks the first explicit product name confirmation outside of internal driver files.
Intel's CES 2026 keynote is scheduled for January 5, 2026. Repository additions typically precede official announcements by 24-48 hours.
What We Know About the BMG-G31 GPU
The Arc B770 uses Intel's BMG-G31 GPU, which has appeared in various leaks and official software since mid-2025.
Expected specifications:
- 32 Xe2 cores (60% more than the B580's 20 cores)
- 16GB GDDR6 memory on a 256-bit bus
- 19 Gbps memory speed with up to 608 GB/s bandwidth
- 300W TDP (NBD shipping manifest from late 2025)
Intel confirmed BMG-G31's existence in December 2025 through VTune Profiler changelog entries and Linux Mesa driver commits. The silicon also appeared in XPU Manager datacenter software.
The Repository Leak Details
The January 4 listing differs from previous BMG-G31 sightings because it explicitly uses the "B770" product name rather than just referencing the GPU die. VideoCardz noted the repository list is somewhat incomplete—it includes the A770 and A750 from Intel's Alchemist generation but omits the B570 and entire A3 series.
Intel's IntelGaming social media account also accidentally referenced the B770 in now-deleted Twitter replies. In December 2025, the account responded enthusiastically to a fan mentioning "B770, Panther Lake, and Nova Lake" before removing the tweet.
Current Mid-Range GPU Market (January 2026)
Nvidia RTX 5060 series (launched April-May 2025):
- RTX 5060 Ti 8GB: $379 MSRP
- RTX 5060 Ti 16GB: $429 MSRP
- RTX 5060 8GB: $299 MSRP (launched May 19, 2025)
The 5060 Ti launch was controversial—reviews dropped the same day cards went on sale (April 16), giving buyers no time to digest coverage. The 8GB models faced immediate criticism for insufficient VRAM. TechPowerUp's review noted the 16GB variant "is realistically available from $500 mark, $70 higher than NVIDIA's starting price."
AMD RX 9060 XT (launched June 5, 2025):
- RX 9060 XT 8GB: $299 MSRP
- RX 9060 XT 16GB: $349 MSRP
AMD announced it at Computex on May 21, 2025. PCGamesN reported AMD emphasized the 16GB variant as making "a great upgrade for gamers looking to future-proof their systems" while saying little about the 8GB model.
Intel Arc B580 (launched December 2024):
- Arc B580 12GB: $249 MSRP
- Still experiencing stock shortages as of January 2026
Performance Expectations
The Arc B580 with 20 Xe2 cores delivers performance roughly equivalent to the RTX 4060 at 1440p, often pulling ahead in VRAM-intensive scenarios. Tom's Hardware and GamersNexus showed the B580 outperforming the RTX 4060 by approximately 10% at 1440p ultra settings.
If core scaling holds, the B770's 32 cores (60% increase) lands it somewhere between current RTX 4070 and RTX 5070 performance. A $350-$450 price point positions the B770 between AMD's RX 9060 XT 16GB and Nvidia's RTX 5060 Ti 16GB, offering more VRAM than the RTX 5070's 12GB while undercutting it by $100-200.
The 300W TDP Question
The leaked 300W TDP is high. For context: RTX 4070 runs 200W. RTX 5070 runs 250W. Arc B580 runs 190W.
At this point, 300W for a mid-range card feels like Intel overcorrecting. Either they're pushing aggressive clocks to match RTX 5070 performance, or the architecture doesn't scale efficiently at larger die sizes. Neither is great.
The 300W figure comes from an NBD shipping manifest spotted in late 2025. These have historically been reliable, though they sometimes list maximum theoretical power rather than typical gaming consumption.
The VRAM Advantage
One clear differentiator: 16GB memory.
As of January 2026, VRAM requirements have increased significantly. Indiana Jones and the Great Circle (December 2025) requires 8GB minimum for high settings with ray tracing. Cyberpunk 2077 with path tracing and Alan Wake 2 can exceed 12GB at 4K ultra.
The RTX 5070's 12GB limitation has become a real constraint—it received criticism for "limited 12GB of VRAM" being "seen as insufficient for the price." GamersNexus's RX 9060 XT review noted that in some ray tracing tests, the RTX 5060 "ran out of VRAM" while the 16GB AMD card continued functioning.
12GB on a $500+ card just isn't defensible anymore.
Real-World Pricing
MSRP means increasingly little. The RX 9060 XT 16GB typically sells for $389 on Amazon despite its $349 MSRP—a $40 premium. The RTX 5060 Ti 16GB frequently sells for $500 or more, $70 above its $429 MSRP.
Intel priced the A770 at $349 and the B580 at $249. If the B770 follows that pattern with a premium for the larger die and more memory, a $399-$449 MSRP seems plausible. Street prices add $40-50.
Driver Maturity
Intel's first-generation Arc launch (2022-2023) suffered from driver instability, DirectX 11 problems, and game compatibility issues. The Arc B580 launch in December 2024 was dramatically smoother. GamersNexus specifically noted the B580 "is far more reliable than the Alchemist cards were at launch."
However, TechSpot's January 2025 re-review revealed B580 performance drops 9-17% when paired with older CPUs (pre-Ryzen 5000 series). Intel's drivers rely heavily on modern CPU architecture and ReBAR support. Buyers with older systems should be cautious.
CES 2026 Timing
Intel's CES 2026 keynote is January 5, 2026, at 3:00 PM PST. The official focus is Panther Lake (Core Ultra 300 series) CPUs and potentially Arrow Lake Refresh. GPU announcements aren't explicitly confirmed, but the repository listing one day before the keynote strongly suggests Arc B-series news.
The timing fits Intel's product cadence. B580 launched December 2024. B570 launched January 2025 at CES. A B770 announcement one year later maintains that pattern.
What This Means for Mid-Range Buyers
If the B770 launches with competitive pricing and adequate supply, it fills a real gap:
$200-$300: Arc B580 (often out of stock), RX 9060 XT 8GB, RTX 5060 8GB
$300-$400: RX 9060 XT 16GB ($389 street price), RTX 5060 Ti 8GB ($379 MSRP but often higher)
$400-$500: RTX 5060 Ti 16GB (frequently $500+), gap before RTX 5070 at $549
A B770 at $399-$449 with 16GB memory and RTX 5070-comparable performance becomes the obvious choice for 1440p gaming. If Intel delivers that at $400 with 16GB, Nvidia has a problem.
The caveat is availability. The B580 launched to positive reviews but immediately sold out. If Intel can't manufacture enough B770 cards, competitive specs become irrelevant.
Conclusion
The Intel Arc B770 repository leak is the strongest indication yet that the card exists and will be announced soon—likely tomorrow at CES 2026.
The BMG-G31 GPU is confirmed through official Intel software. Specifications suggest 32 Xe2 cores, 16GB GDDR6, and 300W TDP. Pricing between $350-$450 seems probable based on Intel's historical positioning. Performance should land between RTX 4070 and RTX 5070.
For gamers in the $300-$500 budget range, the B770 is worth monitoring. If Intel prices competitively and ships real volume, this could be the Arc card that establishes Intel as a credible third option in the mid-range GPU market.
If Intel misses on price or supply, this becomes irrelevant fast. We'll know in about 24 hours.
