Rumors of a successor to Intel's Arc A770 discrete GPU have been floating around for more than a year at this point, with a new launch window finally seeming on the horizon. Following various leaks, the Arc B770, has just appeared on an undisclosed Intel GitHub repository, with code specifically mentioning "b770." While this isn't an official confirmation, it's easy to connect the dots and see the B770 is closer than ever.

Anyhow, prior leaks have revealed some of the specs we can expect in the B770, including the large BMG-G31 die it uses, featuring 32 Xe2 cores. That's a big jump from the 20 Xe cores found on the last-gen A770. The GPU will also feature at least 16GB of GDDR6 VRAM saturated across a 256-bit wide bus. While some rumors point toward more than 16, it's highly unlikely now given the DRAM shortage the industry has plunged into.

The card will compete with AMD's RX 9060-class and Nvidia's RTX 5060-class offerings, with a reported TGP of up to 300W. There's no info on clock speeds, but we know it will be fabricated using TSMC's N5 process, since that's what other Battlemage GPUs use. Intel has also made strides with its driver suite since the last time we saw a B-series card be revealed, which was the B570 at CES 2025, one year ago.

In the past few months, the company has launched workstation-grade offerings under the Xe2 family: Arc Pro B50 and B60, but we haven't seen any new gaming GPUs. On the software side, there are rumors about an in-house multi-frame generation tech in the works at Intel, which could coincide with the launch of the Arc B770.

The timing makes sense since CES 2026 is set to open its doors in just two days - and Intel has a conference scheduled. The arrival of Arc B770 will lend some much-needed competition to Nvidia and AMD in the midrange GPU segment. Of course, it needs to be priced right, but given Intel's track record with Alchemist, it's not unreasonable to get your hopes up.

    B580 vs B770 (leaked specs)
    20 to 32Xe cores: 1.6x
    456GB/s to 608GB/s memory bandwidth: 1.33x
    190W to 300W max power draw: 1.58x

    I eagerly await benchmark numbers and price, but if it's in the same performance range as a 9060XT 16GB to 5060Ti 16GB, and is cheaper than either, that would be an easy choice to make.

    So that would be $350 USD, or the MSRP AMD never achieved for the 9060XT/16GB.

    Interesting time and probably ideal launch given memory prices. This will crush all the 8GB cards out there and probably outprice the mid end 16GB cards.

    It will be curious to see. My bet is ~450 and likely based on ram they procured well in advance of the shortage.

    I'm mostly curious what the client level strategy will be with this card. It is possible that Intel has already acquired the memory needed for whatever volume they're planning. If that's the case then they could be price competitive with the 9060 XT/5060 Ti. It does have the potential to be a 4070 level performing card which would put it a bit above those.

    I mostly just hope that Intel doesn't abandon the client dGPU space, but the lack of discussion and release cadence isn't encouraging.

    Not true, they went down to $340-350 around Nov/Dec, not counting Micro Center where one model was $330.

    Now they are $390, so the good times are over, but they did briefly achieve their MSRP.

    As long as it's cheaper then the xx60+ class cards then it'll be a win. It's really down to price nowadays. Intel is using an older TSMC process, which is cheaper but they'll use more die area. Having it with a full 256 bit memory bus is definitely as advantage over those 128 bit cards.

    pricing in uk is been up and down more down then anything they are however selling out probly since the ram shortage ive seen a uptick over the holidays. ive been waiting for b770 i believe it exists in what form and price well have to wait and see it needs to be 300 pounds or 335 at max if they go over that i wont see it selling well.

    No way is Intel going to sell this for < 400 £/USD even if they bought enough RAM for a year, they will gouge the living life out of the price for max profit but maybe keep it shy of AMD/NV prices, especially with the issues the company is facing.
