Intel Arc B770 vs Intel Arc Pro B70 Comparison

Head-to-Head Benchmarks

The recorded data for the Intel Arc B770 and the Intel Arc Pro B70 does not contain any head-to-head benchmark scores, win counts, or average benchmark scores. Both GPUs show an average benchmark score of 0, and the benchmark comparison table is empty. Consequently, the database cannot provide direct performance deltas between the two cards. What can be derived from the specifications is a clear theoretical performance advantage for the Arc Pro B70 in raw compute. The Arc Pro B70 delivers 22.94 TFLOPS of FP32 throughput against 19.66 TFLOPS for the Arc B770, a difference of approximately 16.7%. In FP16 operations, the Arc Pro B70 reaches 45.88 TFLOPS (2:1) compared to 39.32 TFLOPS (2:1) for the Arc B770, maintaining the same relative gap. This compute advantage stems from a higher boost clock of 2800 MHz versus 2400 MHz, even though both cards share identical core counts.

Memory bandwidth also favors the Arc Pro B70. The Pro card's memory runs at 2375 MHz with 19 Gbps effective speed, producing 608.0 GB/s of bandwidth. The Arc B770 uses 2000 MHz memory at 16 Gbps effective, yielding 512.0 GB/s. That is an 18.75% bandwidth advantage for the Pro variant. Pixel and texture fill rates follow the same pattern: the Arc Pro B70 posts 358.4 GPixel/s and 716.8 GTexel/s, while the Arc B770 posts 307.2 GPixel/s and 614.4 GTexel/s. In every measured throughput metric, the Arc Pro B70 leads, with margins between roughly 16% and 19%. Without actual benchmark results, the database cannot confirm how these theoretical advantages translate into application-level performance, but the specification-level direction is unambiguous.

Architecture Differences

Both the Intel Arc B770 and the Intel Arc Pro B70 are built on the same BMG-G31 chip using the Xe2-HPG architecture, manufactured on a 5 nm process at TSMC. Both share a die size of 368 mm² and use the Battlemage generation, though the Arc B770 is classified under Battlemage (Arc 7) while the Arc Pro B70 falls under Battlemage (Pro Series). Transistor counts are listed as unknown for both, so no comparison can be made there.

The silicon configuration is identical in terms of execution resources. Each GPU has 4096 shading units, 256 texture mapping units, 128 raster operation pipelines, and 32 ray tracing cores. Neither card lists tensor core counts. The API support is exactly the same: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The differences lie in clock behavior, memory configuration, and platform integration. The Arc Pro B70 operates at a base clock of 2280 MHz and a boost clock of 2800 MHz, which is 180 MHz higher at base and 400 MHz higher at boost compared to the Arc B770's 2100 MHz base and 2400 MHz boost. The Pro card also runs its GDDR6 memory faster, at 2375 MHz (19 Gbps effective) versus 2000 MHz (16 Gbps effective). Memory capacity differs substantially: the Arc Pro B70 carries 32 GB, double the 16 GB of the Arc B770. Both use a 256 bit memory bus, so the bandwidth increase comes purely from the higher memory clock.

Power delivery and connectivity also separate the two. The Arc B770 has a TDP of 225 W with two power connectors (1x 6-pin plus 1x 8-pin), while the Arc Pro B70 has a TDP of 230 W with a single 8-pin connector. Both recommend a 550 W power supply. The bus interface differs: the Arc B770 uses PCIe 4.0 x16, while the Arc Pro B70 uses PCIe 5.0 x16. Display outputs are identical, with 1x HDMI 2.1a and 3x DisplayPort 2.1 on both cards. The Arc Pro B70 has recorded physical dimensions of 267 mm length, 110 mm height, and 39 mm width, while the Arc B770 lists no dimensions in the database.

Fields that are identical between the two cards include the chip (BMG-G31), architecture (Xe2-HPG), process node (5 nm TSMC), die size (368 mm²), shading units (4096), TMUs (256), ROPs (128), ray tracing cores (32), memory type (GDDR6), bus width (256 bit), slot width (Dual-slot), suggested PSU (550 W), display outputs (1x HDMI 2.1a, 3x DisplayPort 2.1), and API support (DirectX 12 Ultimate 12_2, OpenGL 4.6, Vulkan 1.4).

The Verdict

The data indicates that the Intel Arc Pro B70 is the stronger card across every specification-based performance metric. It delivers higher clocks, more memory, greater bandwidth, and higher compute throughput than the Intel Arc B770. The FP32 advantage of 22.94 TFLOPS versus 19.66 TFLOPS and the bandwidth advantage of 608.0 GB/s versus 512.0 GB/s are the most significant differences. The Pro card also adds PCIe 5.0 x16 support, which the B770 lacks. The B770 does have a lower TDP at 225 W versus 230 W, and it requires two power connectors instead of one, but these are minor trade-offs against the Pro card's consistent performance lead.

There are no benchmark results in the database to validate real-world performance, so the verdict rests entirely on specifications. From that perspective, the Intel Arc Pro B70 is the more capable GPU. It also carries a launch MSRP of 949 USD, while the Arc B770 has no listed launch MSRP. The Arc B770 was released on 2025-12-31, and the Arc Pro B70 followed on 2026-03-25. The B70's later release date aligns with its higher specification profile.

Where Each One Wins

The Intel Arc Pro B70 wins in compute-heavy workloads based on its 22.94 TFLOPS FP32 and 45.88 TFLOPS FP16 figures. Applications that scale with raw shader throughput, such as rendering, simulation, or compute offload, will benefit from the Pro card's higher boost clock of 2800 MHz. The 32 GB memory capacity and 608.0 GB/s bandwidth make it the choice for large datasets, high-resolution textures, or workloads that exceed the 16 GB frame buffer of the B770. The PCIe 5.0 x16 interface also provides a platform-level advantage for data transfer between the GPU and system memory.

The Intel Arc B770 wins only in power efficiency by a narrow margin. Its TDP of 225 W is 5 W lower than the Arc Pro B70's 230 W, while delivering roughly 86% of the FP32 throughput. The B770 also uses a 1x 6-pin plus 1x 8-pin power configuration compared to the single 8-pin on the Pro card, which may matter for installations where an extra connector is available or preferred. For scenarios where the full 32 GB frame buffer is unnecessary and the lower power draw is prioritized, the B770 remains a viable option. However, the database shows no benchmark wins for either card, so these conclusions follow from specification analysis rather than measured performance.
