Product comparison
Compare Intel Arc A770 and B580 by 16GB versus 12GB capacity, current 1440p value, board power, PCIe fit, application support, and price.
Updated 2026-08-23
Buying decision
Arc B580 is the default new-build value choice at the tracked prices, with cited 12GB memory, 190W board power, and a $212 reference. Arc A770 remains relevant when a specific 16GB board is deeply discounted and a tested workload benefits from the extra capacity. Compare current game and application results before choosing memory size or generation in isolation.
Intel Arc A770
A770 belongs on the shortlist only when you find the 16GB version below the B580's total cost and your game or creator application can use capacity above 12GB. Verify the exact board, condition, power connectors, return coverage, and application support before buying clearance or used inventory.
Intel Arc B580
B580 is tracked at $212 and its cited Intel page confirms 12GB of GDDR6, 456GB/s bandwidth, 190W board power, and a PCIe 4.0 x8 interface. It is the easier starting point for a 1440p value build, provided recent tests cover your games and the x8 link is a good fit for the host platform.
new 1440p value build
B580 combines the lower tracked price with a cited 12GB memory configuration; confirm results for your game list before purchase.
memory-sensitive 16GB workload
A770 is the candidate when a verified 16GB board is discounted and testing shows the workload benefits from capacity beyond B580's 12GB.
lower board-power target
Intel's cited 190W board-power figure for B580 is lower than the A770 reference in this catalog, though partner cards and the full system still need checking.
value builds
B580 is $67 lower at the tracked references and has a current official specification source, making it the more defensible default value choice.
Intel Arc A770 is tracked at $279, about 20% below its $349 launch reference, while Intel Arc B580 is tracked at $212, about 15% below its $249 launch reference. Intel Arc B580 currently carries the lower editorial reference by $67, but that saving only matters if it still covers the features you use every week. Intel Arc A770 remains a current-market option, but the exact US SKU and checkout price still need a retailer check; Intel Arc B580 remains a current-market option, but the exact US SKU and checkout price still need a retailer check. These figures are not live offers, so re-check retailer pricing and return terms before buying.
Recommendation
Intel Arc B580 is the stronger default for value 1440p and budget midrange builds, mainly because it pulls ahead on price to performance and power efficiency. Pick Intel Arc A770 only if you specifically need what it does better day to day.
Winner for most buyers
Intel Arc B580
Arc B580 belongs on a value shortlist when its 12GB capacity and measured performance beat similarly priced GeForce or Radeon options in the games you play. Choose another platform when a professional application requires CUDA, a specific vendor feature, or proven support that matters more than the purchase price.

Every value shows its editorial trust state. “Needs confirmation” means the field has not completed field-level source review; it does not mean the value is known to be wrong.
These sources support the specification fields identified on the linked product pages. Unbadged fields remain editorial reference data, and price or regional availability should be checked again before purchase.
The A770 case rests on finding the 16GB version at a genuine clearance or used discount and having a game or creator workload that benefits from capacity above 12GB. At the current editorial references it is $67 more expensive than the B580, so it is not the automatic budget choice. Verify the exact board, return coverage, power connectors, and application compatibility before treating memory capacity alone as a reason to buy the older card.
B580 starts from the stronger value position here: the cited Intel specifications confirm 12GB of GDDR6, a 192-bit bus, 456GB/s bandwidth, 190W board power, and a PCIe 4.0 x8 interface, while the tracked reference is $212. The 12GB capacity is the compromise against a 16GB A770, but the $67 saving can fund a power-supply or storage upgrade. Check the x8 interface carefully if the rest of the system is limited to an older PCIe generation.
Compare recent results for your exact games at the target resolution, including one-percent lows, ray tracing, upscaling quality, and frame-generation behavior rather than relying on a single average. For creator or compute work, confirm that the application supports Intel Arc and does not require CUDA before either card reaches the shortlist. Recalculate the total with the required power supply, display outputs, return policy, and current board-partner price because those costs can erase a small GPU discount.
