Intel Arc B770 vs Intel Arc Pro A60M Comparison

Intel Arc B770 and Intel Arc Pro A60M represent two very different interpretations of Intel's GPU architecture, separated by process node, generation, and intended deployment. The B770 is a large desktop-class Battlemage part aimed at high-throughput workloads, while the A60M is a compact Alchemist-based mobile professional GPU. The recorded data shows a substantial gap in raw compute capability, but the A60M retains specific advantages in efficiency and form factor that matter for its target segment.

Where Each One Wins

The Intel Arc B770 dominates in every absolute performance category recorded in the database. Its FP32 throughput of 19.66 TFLOPS is roughly 3.7 times the A60M's 5.325 TFLOPS. Pixel fill rate follows a similar pattern, with the B770 delivering 307.2 GPixel/s versus 83.20 GPixel/s for the A60M, a 3.7x advantage. Texture rate tells the same story: 614.4 GTexel/s against 166.4 GTexel/s, again a 3.7x gap. These ratios are consistent because the B770 doubles the A60M's shading units, TMUs, and ROPs while also running at significantly higher clocks.

The B770 also wins on memory capacity and bandwidth. It carries 16 GB of GDDR6 on a 256-bit bus, yielding 512.0 GB/s of bandwidth. The A60M has 8 GB on a 128-bit bus, producing 256.0 GB/s. That is exactly double the capacity and double the bandwidth, which gives the B770 a clear edge for datasets that exceed 8 GB or workloads that saturate memory bandwidth.

The A60M wins where power and physical footprint matter. Its TDP of 95 W is less than half the B770's 225 W. The A60M is an IGP (integrated graphics processor) package, meaning it is designed for direct mounting on a board rather than as a discrete expansion card. The B770 is a dual-slot card requiring both a 6-pin and an 8-pin power connector and a 550 W suggested PSU. The A60M needs no external power connectors. For mobile workstations and compact embedded systems, the A60M is the only viable option between the two.

The B770 also leads in display output flexibility. It provides 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs. The A60M's display outputs are listed as "Portable Device Dependent," meaning the manufacturer of the host device determines the ports. Desktop users get predictable, high-bandwidth connectors on the B770, while the A60M's outputs vary by implementation.

Architecture Differences

The two GPUs come from different Intel generations, though both use the Xe-HPG architecture family. The B770 is built on Xe2-HPG, the second-generation implementation, and belongs to the Battlemage (Arc 7) generation. The A60M uses the original Xe-HPG architecture from the Alchemist generation, specifically the Pro-Series Mobile variant. The B770's chip is designated BMG-G31, while the A60M uses DG2-256.

Process technology differs as well. The B770 is fabricated on a 5 nm process at TSMC, while the A60M uses TSMC's 6 nm node. The B770's die measures 368 mm², larger than the A60M's 269 mm². The A60M's transistor count is recorded at 11,500 million, with a transistor density of 42.8M per mm². The B770's transistor count is listed as unknown, so a direct density comparison is not possible from the recorded data.

The compute configuration scales by a factor of two across most units. The B770 has 4096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. The A60M has 2048 shading units, 128 TMUs, 64 ROPs, and 16 ray tracing cores. The B770 doubles each of these resources. Tensor core counts are not listed for either GPU, so no comparison can be made there.

Clock behavior differs substantially. The B770 runs at a 2100 MHz base and 2400 MHz boost. The A60M runs at 900 MHz base and 1300 MHz boost. That is a 1200 MHz difference at base and a 1100 MHz difference at boost. The B770's higher clocks compound its doubling of execution resources, which explains why the FP32, pixel rate, and texture rate gaps are all near 3.7x rather than exactly 2x.

Memory clocks are identical at 2000 MHz with 16 Gbps effective data rate for both GPUs. The bandwidth difference comes entirely from bus width: 256 bits versus 128 bits. Both use GDDR6 memory. Both support PCIe 4.0 x16 interfaces and share the same API feature set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The A60M's production status is listed as Active, while the B770 has no recorded production status. The A60M was released on 2025-06-06 in the database's recorded timeline, and the B770's release date is listed as 2026-01-01. The B770's predecessor is recorded as Alchemist, which is the architecture family the A60M belongs to, indicating a direct generational lineage.

The Verdict

The data points to a clear performance hierarchy. The B770 is the stronger GPU in every measured compute metric. Its FP32 output of 19.66 TFLOPS, doubled shading units, doubled ROPs, doubled ray tracing cores, and doubled memory bandwidth make it the choice for workloads that need maximum throughput. The 16 GB frame buffer also allows it to handle working sets that would exceed the A60M's 8 GB capacity.

The A60M is the appropriate selection when power envelope and physical integration take priority over raw performance. Its 95 W TDP, IGP form factor, and lack of external power connectors suit mobile workstations and embedded designs where a dual-slot card with a 550 W PSU requirement is impractical. Its 5.325 TFLOPS FP32 and 256.0 GB/s bandwidth are modest but serviceable for professional mobile graphics tasks that do not demand the B770's full resources.

The B770's 3.7x lead in fill rates and compute is significant enough that any application which can use the additional throughput will see a major difference. The A60M's advantage is not in speed but in integration efficiency. Neither GPU has recorded benchmark scores or nearest rival data in the database, so the verdict rests entirely on the architectural specifications. The B770 targets desktop performance, the A60M targets mobile professional deployment, and the data confirms they occupy different tiers.

Head-to-Head Benchmarks

No direct head-to-head benchmark entries exist in the database for these two GPUs. The comparison must be drawn from their recorded specifications, which are extensive.

The largest measured gap is in pixel fill rate. The B770 processes 307.2 GPixel/s, while the A60M manages 83.20 GPixel/s. The B770 therefore operates at 3.7 times the A60M's pixel throughput. In practical terms, a rendering workload that is fill-limited will complete in roughly a quarter of the time on the B770, assuming the rest of the system does not bottleneck.

Texture rate shows the identical ratio. The B770 reaches 614.4 GTexel/s, and the A60M reaches 166.4 GTexel/s. This is exactly 3.7x, matching the pixel rate gap. The consistency of these ratios across pixel and texture units indicates that both GPUs scale their fixed-function units proportionally, with the B770 doubling the A60M's ROP and TMU counts and then adding the clock advantage.

FP32 compute follows the same pattern. The B770's 19.66 TFLOPS divided by the A60M's 5.325 TFLOPS yields a 3.7x factor. FP16 performance also scales by 2:1 on both parts, with the B770 at 39.32 TFLOPS and the A60M at 10.65 TFLOPS. The B770's advantage holds across both precision formats.

Memory bandwidth is the one category that shows exactly a 2x difference rather than 3.7x. The B770 delivers 512.0 GB/s versus the A60M's 256.0 GB/s. The memory clock is identical at 2000 MHz with 16 Gbps effective on both, so the entire bandwidth gap comes from the bus width difference. This means workloads that are purely bandwidth-bound will see a smaller relative improvement than compute-bound workloads.

The clock speed difference deserves attention. The B770 boosts to 2400 MHz, while the A60M boosts to 1300 MHz. The base clocks are 2100 MHz and 900 MHz respectively. These clock gaps, combined with the doubled execution resources, produce the multiplicative performance difference seen in the fill rates and compute figures.

The A60M's die is 269 mm² with 11,500 million transistors at a density of 42.8M per mm². The B770's die is 368 mm², but its transistor count is unknown, so the B770's density cannot be calculated from the recorded data. The A60M's smaller die and lower TDP reflect its mobile design intent. The B770's larger die and 225 W TDP reflect a desktop part that prioritizes throughput over efficiency.

Both GPUs use GDDR6 memory and PCIe 4.0 x16 interfaces. Both support the same API versions. The B770's display output suite of 1x HDMI 2.1a and 3x DisplayPort 2.1 is fixed and documented, whereas the A60M's outputs depend on the host device. The A60M's release date is recorded as 2025-06-06 and its production status is Active, while the B770 has a later recorded release date of 2026-01-01 and no production status listed. The B770's predecessor is listed as Alchemist, which is the architecture generation that includes the A60M, confirming the generational step.
