Intel Arc Pro B70 vs Intel UHD Graphics 770 Mobile Comparison

Intel Arc Pro B70 and Intel UHD Graphics 770 Mobile sit at opposite ends of the graphics spectrum, one a dedicated professional workstation card and the other an integrated solution for laptops. The database shows a clear separation in raw specifications and intended use cases, though both share the Intel graphics family lineage. This analysis relies solely on recorded specifications and architectural data.

The Verdict

The Intel Arc Pro B70 is the choice for professionals requiring dedicated rendering power, large memory capacity, and discrete display outputs. Its 32 GB of GDDR6 memory, 4096 shading units, and 230 W power envelope indicate a workstation-class part built for sustained compute loads. The Intel UHD Graphics 770 Mobile, by contrast, serves as a basic display adapter for portable systems, with 256 shading units and a 15 W TDP that fits the IGP form factor.

The data indicates the Arc Pro B70 targets users who need PCIe 5.0 x16 bandwidth, multi-display setups via 1x HDMI 2.1a and 3x DisplayPort 2.1, and a dual-slot cooling solution. The UHD 770 Mobile targets users who prioritize battery life and compactness, with system-shared memory and a Ring Bus interface that requires no dedicated power connectors. Neither part suits the other's market, so the verdict depends entirely on whether the workload demands discrete graphics or integrated efficiency.

Architecture Differences

The Arc Pro B70 uses the BMG-G31 chip built on Xe2-HPG architecture, fabricated on a 5 nm process by TSMC, with a die size of 368 mm². This architecture supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and includes 32 dedicated ray tracing cores. The UHD 770 Mobile uses the Raptor Lake chip on Generation 12.2 architecture, built on Intel's 10 nm process, with no dedicated ray tracing cores and DirectX 12 (12_1) support.

The process node difference, 5 nm versus 10 nm, explains the density gap: the Arc Pro B70 packs 4096 shading units, 256 texture mapping units, and 128 raster operation units into its 368 mm² die, while the UHD 770 Mobile fits 256 shading units, 16 TMUs, and 8 ROPs into an unspecified die size. The Arc Pro B70's clock speeds run from 2280 MHz base to 2800 MHz boost, while the UHD 770 Mobile operates at 300 MHz base and 1600 MHz boost. The Arc Pro B70 also features GDDR6 memory at 2375 MHz with 19 Gbps effective speed, whereas the UHD 770 Mobile uses system-shared memory with bandwidth labeled as system dependent.

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results between these two GPUs, as the head-to-head benchmarks field is empty. However, the specification data provides a clear performance hierarchy. The Arc Pro B70 delivers 22.94 TFLOPS of FP32 compute, which is 28 times the 819.2 GFLOPS of the UHD 770 Mobile. In pixel throughput, the Arc Pro B70 achieves 358.4 GPixel/s versus 12.80 GPixel/s for the UHD 770 Mobile, a 28-fold difference. Texture rate follows the same pattern: 716.8 GTexel/s versus 25.60 GTexel/s.

The memory bandwidth gap is similarly decisive. The Arc Pro B70's 608.0 GB/s GDDR6 bandwidth dwarfs the system-dependent bandwidth of the UHD 770 Mobile, which shares memory with the CPU. The Arc Pro B70's 32 GB VRAM capacity supports large datasets and complex scenes that the UHD 770 Mobile cannot address, since its memory is limited by the host system's RAM allocation. The clock speed advantage, 2800 MHz boost versus 1600 MHz boost, further compounds the architectural differences in shading units, TMUs, and ROPs.

Where Each One Wins

The Arc Pro B70 wins in every compute-intensive category. Its 32 ray tracing cores enable hardware-accelerated ray tracing, a feature absent from the UHD 770 Mobile. The 12 Ultimate DirectX support allows for the latest graphics features, while the UHD 770 Mobile's DirectX 12 (12_1) lacks the full 12_2 feature set. The 256-bit memory bus and 608.0 GB/s bandwidth handle high-resolution textures and multi-monitor workloads, supported by the 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs. The dual-slot design and 230 W TDP indicate sustained performance capability for professional rendering applications.

The UHD 770 Mobile wins in power efficiency and system integration. Its 15 W TDP is a fraction of the Arc Pro B70's 230 W, making it suitable for thin-and-light laptops. The IGP form factor requires no additional space, no power connectors, and no dedicated cooling, unlike the Arc Pro B70's 267 mm length, 110 mm height, and 39 mm width. The Ring Bus interface eliminates the need for PCIe slot allocation, and the system-shared memory reduces component cost. The UHD 770 Mobile's release date of 2023-01-03 also predates the Arc Pro B70's 2026-03-25 launch, giving it a longer presence in the mobile market.

The production status further separates them: the UHD 770 Mobile is listed as active, while the Arc Pro B70 has no production status recorded. The UHD 770 Mobile also has a documented successor, Arc Graphics-M, indicating an ongoing product line, whereas the Arc Pro B70 has no successor listed. For users with existing mobile platforms, the UHD 770 Mobile provides basic graphics output without additional hardware. For users building or upgrading a workstation, the Arc Pro B70 delivers the full complement of professional features, including the 22.94 TFLOPS FP32 compute and 45.88 TFLOPS FP16 performance, at a launch MSRP of 949 USD. The choice is binary: integrated efficiency versus dedicated power.
