Architecture Differences

The Intel Arc Pro B60 Dual and Intel UHD Graphics 770 Mobile represent two entirely different design philosophies within Intel's product stack. The Arc Pro B60 Dual is built on the Xe2-HPG architecture, part of the Battlemage (Pro Series) generation, and fabricated on TSMC's 5 nm process. This process node allows for a dense transistor layout: the chip contains 19,600 million transistors on a 272 mm² die, yielding a transistor density of 72.1M per mm². In contrast, the UHD Graphics 770 Mobile uses the Generation 12.2 architecture with the Raptor Lake chip on Intel's 10 nm process. The database does not list transistor count or die size for the integrated part.

The execution resource disparity is substantial. The Arc Pro B60 Dual fields 2,560 shading units, 160 texture mapping units, and 80 raster operation pipelines. It also includes 20 dedicated ray tracing cores, a feature entirely absent from the UHD Graphics 770 Mobile, which has no ray tracing hardware listed. The integrated GPU manages 256 shading units, 16 TMUs, and 8 ROPs, exactly one-tenth of the shading units and one-fifth of the ROPs of the discrete card.

Clock behavior further separates the two. The Arc Pro B60 Dual operates at a 2000 MHz base and 2400 MHz boost, while the UHD Graphics 770 Mobile idles at a 300 MHz base and reaches only 1600 MHz boost. The memory architecture is fundamentally different: the Arc Pro B60 Dual uses dedicated GDDR6 memory with a 192-bit bus and 456.0 GB/s bandwidth, whereas the UHD Graphics 770 Mobile shares system memory with bandwidth described only as System Dependent.

The power envelope tells the story of their intended placements. The Arc Pro B60 Dual draws up to 400 W, requires an 800 W suggested PSU, and uses a 1x 16-pin power connector. The UHD Graphics 770 Mobile operates within a 15 W TDP as an integrated solution with a Ring Bus interface. The Arc Pro B60 Dual connects via PCIe 5.0 x8, while the mobile IGP uses the Ring Bus for system integration.

The Verdict

The data presents a clear hierarchical relationship. The Intel Arc Pro B60 Dual is a professional discrete graphics card with dedicated memory, ray tracing cores, and a 400 W power budget. The Intel UHD Graphics 770 Mobile is an integrated solution with shared memory, no ray tracing, and a 15 W power envelope. The Arc Pro B60 Dual delivers 15.0 times the FP32 throughput (12.29 TFLOPS versus 819.2 GFLOPS) and 15.0 times the pixel rate (192.0 GPixel/s versus 12.80 GPixel/s). Its texture rate of 384.0 GTexel/s is exactly 15 times the 25.60 GTexel/s of the integrated part.

The Arc Pro B60 Dual also offers a full 24 GB of dedicated GDDR6 memory with 456.0 GB/s bandwidth, compared to the System Shared memory of the UHD Graphics 770 Mobile. The discrete card supports DirectX 12 Ultimate (12_2), while the integrated GPU is limited to DirectX 12 (12_1), a meaningful difference for modern graphics workloads. The Arc Pro B60 Dual includes 20 RT cores, enabling hardware-accelerated ray tracing that the UHD Graphics 770 Mobile cannot perform.

The UHD Graphics 770 Mobile, however, has a decisive advantage in power efficiency. Its 15 W TDP is 26.7 times lower than the 400 W TDP of the Arc Pro B60 Dual. The integrated GPU was released on 2023-01-03, while the Arc Pro B60 Dual came later on 2025-09-04. The UHD Graphics 770 Mobile has a listed successor, Arc Graphics-M, indicating its position in an active product line. The Arc Pro B60 Dual has no listed predecessor or successor.

The Arc Pro B60 Dual is the only choice for workloads requiring dedicated memory, ray tracing, or high-throughput compute. The UHD Graphics 770 Mobile serves systems where power consumption and physical footprint are the primary constraints.

Head-to-Head Benchmarks

The recorded measurements show no direct head-to-head benchmark entries in the database, and both products hold a 50th percentile rank among all GPUs with an average benchmark score of zero. The comparison must therefore proceed through the specification-derived performance indicators.

The FP32 compute output demonstrates the scale of difference. The Arc Pro B60 Dual delivers 12.29 TFLOPS, which is 15.0 times the 819.2 GFLOPS of the UHD Graphics 770 Mobile. In FP16, the Arc Pro B60 Dual reaches 24.58 TFLOPS (2:1), compared to 1.638 TFLOPS (2:1) for the integrated part, a 15.0-fold advantage. This ratio holds consistently across pixel rate and texture rate, indicating that the Arc Pro B60 Dual's advantage is uniform across different workload types rather than concentrated in one subsystem.

The pixel rate of 192.0 GPixel/s for the Arc Pro B60 Dual versus 12.80 GPixel/s for the UHD Graphics 770 Mobile translates to a 15.0 times advantage in fill-rate-bound scenarios. The texture rate of 384.0 GTexel/s versus 25.60 GTexel/s gives the same 15.0 times multiplier. This consistency suggests the architectural scaling from 256 to 2,560 shading units, combined with the higher clock speeds, produces predictable performance scaling.

Memory bandwidth presents the largest practical gap. The Arc Pro B60 Dual offers 456.0 GB/s of dedicated bandwidth, while the UHD Graphics 770 Mobile depends on System Shared memory with System Dependent bandwidth. In memory-intensive workloads, the discrete card's dedicated GDDR6 memory eliminates contention with the CPU for system memory bandwidth. The 24 GB capacity versus System Shared means the Arc Pro B60 Dual can hold large datasets entirely in graphics memory.

The ray tracing capability is binary. The Arc Pro B60 Dual includes 20 RT cores, enabling hardware-accelerated ray tracing. The UHD Graphics 770 Mobile has no RT cores listed, meaning any ray tracing workload would fall back to compute shaders, severely limiting its viability for that use case.

Where Each One Wins

The Intel Arc Pro B60 Dual wins in every compute and graphics throughput category recorded in the database. Its 12.29 TFLOPS FP32 and 24.58 TFLOPS FP16 output suit general-purpose compute workloads, including scientific simulation and machine learning inference. The 20 RT cores make it the only option for hardware-accelerated ray tracing. The 24 GB GDDR6 memory with 456.0 GB/s bandwidth supports large textures, high-resolution rendering, and data-intensive compute tasks. The 4x mini-DisplayPort 2.1 outputs enable multi-display professional setups. The 400 W power budget and 1x 16-pin connector indicate a workstation-class component designed for sustained high load. The DirectX 12 Ultimate (12_2) support provides access to the latest graphics features.

The Intel UHD Graphics 770 Mobile wins in power efficiency and system integration. Its 15 W TDP allows operation in thermally constrained portable devices without additional cooling or power delivery hardware. The Ring Bus interface means no dedicated PCIe slot is required. The System Shared memory model eliminates the need for separate video memory, reducing system cost and complexity. The absence of a power connector and suggested PSU requirement confirms its drop-in nature for mobile platforms. The 300 MHz base clock and 1600 MHz boost clock are sufficient for basic display output and light 2D workloads. Its release on 2023-01-03 and active production status with a listed successor (Arc Graphics-M) indicates ongoing support in the mobile segment.

The Arc Pro B60 Dual carries a launch MSRP of 1,199 USD, positioning it as a professional-grade component. The UHD Graphics 770 Mobile has no listed launch MSRP, consistent with its role as an integrated solution bundled with the Raptor Lake chip. The choice between them is determined entirely by the target platform: the Arc Pro B60 Dual for dedicated graphics workstations, the UHD Graphics 770 Mobile for power-efficient portable systems.
