Intel Arc B770 vs Intel Arc Pro B60 Dual Comparison

# Intel Arc B770 vs Intel Arc Pro B60 Dual

The Intel Arc B770 and Intel Arc Pro B60 Dual are both built on the Xe2-HPG architecture and the 5 nm TSMC process, but they target different workloads. The B770 is a Battlemage (Arc 7) generation part with a BMG-G31 chip, while the Pro B60 Dual is a Battlemage (Pro Series) part with a BMG-G21 chip. The database records no head-to-head benchmark scores for this pair, so the analysis below relies on the measured specifications and recorded capabilities of each card. The B770 offers higher raw compute and rendering throughput, while the Pro B60 Dual provides more memory capacity and a different interface layout.

Where Each One Wins

The Intel Arc B770 wins in scenarios that demand peak shading and texture throughput. It carries 4096 shading units, 256 texture mapping units, and 128 raster operation units, compared to 2560 shading units, 160 TMUs, and 80 ROPs on the Pro B60 Dual. The B770 also has 32 ray tracing cores versus 20 on the Pro card. For FP32 compute, the B770 reaches 19.66 TFLOPS, which is roughly 60% higher than the Pro B60 Dual's 12.29 TFLOPS. Pixel fill rate on the B770 is 307.2 GPixel/s versus 192.0 GPixel/s, and texture fill rate is 614.4 GTexel/s versus 384.0 GTexel/s. Any workload that is heavily dependent on shader execution, ray tracing, or fill rate will favor the B770.

The Intel Arc Pro B60 Dual wins in memory capacity and interface flexibility. It packs 24 GB of GDDR6 memory, which is 8 GB more than the B770's 16 GB. The Pro card uses a 192 bit memory bus with 456.0 GB/s of bandwidth, while the B770 uses a 256 bit bus with 512.0 GB/s. Although the B770 has higher peak bandwidth, the Pro card's larger capacity suits datasets that exceed 16 GB. The Pro B60 Dual also uses a PCIe 5.0 x8 interface, while the B770 uses PCIe 4.0 x16. The Pro card's four mini-DisplayPort 2.1 outputs support multi-display professional setups, whereas the B770 offers one HDMI 2.1a and three DisplayPort 2.1 outputs. The Pro B60 Dual is marked as Active in production status, and it has a recorded launch MSRP of 1,199 USD.

Architecture Differences

Both cards are fabricated on the 5 nm process at TSMC and use the Xe2-HPG architecture, but the silicon differs. The B770 uses the BMG-G31 chip with a die size of 368 mm², while the Pro B60 Dual uses the BMG-G21 chip with a die size of 272 mm². The Pro card's transistor count is recorded at 19,600 million, with a transistor density of 72.1M per mm². The B770's transistor count is listed as unknown in the database.

Clock behavior differs slightly. The B770 has a base clock of 2100 MHz and a boost clock of 2400 MHz. The Pro B60 Dual has a base clock of 2000 MHz and the same 2400 MHz boost. Memory clocks differ as well: the B770 runs at 2000 MHz with 16 Gbps effective speed, while the Pro card runs at 2375 MHz with 19 Gbps effective speed. Despite the higher memory clock, the Pro card's narrower 192 bit bus results in lower total bandwidth.

The power delivery and board design diverge sharply. The B770 is rated at 225 W TDP with a 1x 6-pin plus 1x 8-pin power connector setup and a suggested 550 W PSU. The Pro B60 Dual is rated at 400 W TDP with a single 16-pin connector and a suggested 800 W PSU. Both are dual-slot cards, but the Pro B60 Dual has recorded dimensions of 300 mm length, 110 mm height, and 40 mm width. The B770's dimensions are not recorded.

API support is identical: both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Pro B60 Dual's predecessor field is null, while the B770's predecessor is listed as Alchemist.

Head-to-Head Benchmarks

The database contains no direct benchmark scores for the Intel Arc B770 versus the Intel Arc Pro B60 Dual. Both cards have an average benchmark score of 0 and a percentile versus all GPUs of 50 in the recorded data. There are no nearest rivals listed for either card, and no win counts are recorded for the head-to-head comparison. This means the performance relationship must be derived from the specification deltas.

The FP32 compute gap is significant. The B770's 19.66 TFLOPS is about 60% higher than the Pro B60 Dual's 12.29 TFLOPS. In practical terms, the B770 can execute roughly 7.37 TFLOPS more FP32 work per second. The FP16 figures follow the same pattern: the B770 delivers 39.32 TFLOPS (2:1) versus 24.58 TFLOPS (2:1) on the Pro card, a lead of about 14.74 TFLOPS. Texture rate favors the B770 by 230.4 GTexel/s, and pixel rate favors it by 115.2 GPixel/s.

The ray tracing core count difference is 32 versus 20, a 12 core advantage for the B770. Shader unit count favors the B770 by 1536 units, TMUs by 96, and ROPs by 48. These differences indicate that the B770 is the stronger card for rendering and compute-heavy tasks, while the Pro B60 Dual compensates with 8 GB of additional memory capacity and a faster PCIe 5.0 interface, albeit with a narrower x8 link.

Memory bandwidth is one area where the B770 retains a lead despite the Pro card's higher memory clock. The B770's 512.0 GB/s exceeds the Pro card's 456.0 GB/s by 56.0 GB/s. The Pro card's 192 bit bus limits its bandwidth despite running at 19 Gbps effective, while the B770's 256 bit bus at 16 Gbps effective provides more total throughput. For workloads that are bandwidth-bound rather than capacity-bound, the B770 is the better choice.

The Verdict

The data points to a clear split. The Intel Arc B770 is the stronger compute and rendering card, with higher FP32 throughput, more shading units, more ray tracing cores, and higher fill rates. Its 512.0 GB/s memory bandwidth also exceeds the Pro card's 456.0 GB/s, and it does so at a much lower 225 W TDP. For any task that stresses shader execution, ray tracing, or raw pixel throughput, the B770 is the logical pick.

The Intel Arc Pro B60 Dual is the choice when memory capacity and system interface matter more than raw throughput. Its 24 GB frame buffer accommodates larger datasets, and its PCIe 5.0 x8 interface provides a newer link generation. The four mini-DisplayPort 2.1 outputs suit multi-display professional environments. The 400 W TDP and 800 W suggested PSU indicate a more demanding power requirement, and the recorded launch MSRP of 1,199 USD positions it as a professional workstation product.

There are no recorded benchmark scores for either card in the database, so these conclusions rest entirely on the specification differences. The B770 delivers roughly 60% more FP32 compute and nearly identical memory bandwidth on a smaller power budget, making it the better all-around performer on paper. The Pro B60 Dual offers 50% more memory capacity and a newer PCIe generation, which are meaningful advantages for specific professional workloads. The choice depends on whether the workload is bound by compute throughput or by memory capacity and interface generation.
