Intel Arc Pro B65 vs Intel UHD Graphics 770 Mobile Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark runs between the Intel Arc Pro B65 and the Intel UHD Graphics 770 Mobile. Both products share the same overall percentile ranking against all GPUs (50th percentile), indicating that in the aggregate scoring system, neither part separates itself from the other on a normalized curve. However, the raw computational specifications reveal a dramatic performance gulf that would manifest across virtually every workload category.

The Arc Pro B65 delivers 12.29 TFLOPS of FP32 compute, while the UHD Graphics 770 Mobile manages 819.2 GFLOPS. That represents a 15-fold difference in raw single-precision throughput. In FP16, the Arc Pro B65 reaches 24.58 TFLOPS (2:1 ratio), compared to 1.638 TFLOPS for the integrated part, again a 15-fold margin. Pixel throughput shows a similar chasm: the Arc Pro B65 renders 192.0 GPixel/s versus 12.80 GPixel/s for the UHD 770, a 15x gap. Texture rate tells the same story: 384.0 GTexel/s against 25.60 GTexel/s, exactly 15 times higher.

The memory subsystem amplifies these differences. The Arc Pro B65 uses 32 GB of GDDR6 on a 256-bit bus, delivering 608.0 GB/s of bandwidth. The UHD Graphics 770 Mobile relies on System Shared memory with bandwidth described only as "System Dependent." In practice, shared-memory implementations typically deliver far lower bandwidth than dedicated VRAM, though the exact figures are not recorded in the database.

Clock behavior also distinguishes the two. The Arc Pro B65 runs at a flat 2400 MHz for both base and boost, meaning sustained load performance remains constant. The UHD Graphics 770 Mobile idles at 300 MHz and boosts to 1600 MHz, a much wider frequency range that introduces variable performance depending on thermal and power headroom. The dedicated card's memory clock sits at 2375 MHz (19 Gbps effective), a fixed specification entirely absent from the integrated part's shared-memory design.

Since no direct benchmark scores exist, the head-to-head comparison relies on these recorded specifications. The Arc Pro B65 outperforms the UHD Graphics 770 Mobile by exactly 15x in FP32, FP16, pixel fill rate, and texture fill rate. These are not approximate figures; they are precise multiples derived from the database entries.

Where Each One Wins

The Arc Pro B65 wins in every scenario that demands sustained, high-throughput graphics processing. Its 2560 shading units, 160 TMUs, and 80 ROPs provide the execution resources for heavy 3D workloads, GPU-accelerated rendering, and compute tasks. The 20 ray tracing cores add hardware acceleration for ray-traced effects, a feature the UHD Graphics 770 Mobile lacks entirely (its RT core count is null in the database). The 32 GB GDDR6 frame buffer supports large datasets, high-resolution textures, and multi-display configurations. Four DisplayPort 2.1 outputs allow professional multi-monitor setups.

The UHD Graphics 770 Mobile wins in power efficiency and physical integration. Its 15 W TDP is a tiny fraction of the Arc Pro B65's 200 W TDP. It requires no power connector, no slot space (IGP form factor), and no separate PSU recommendation. It uses the Ring Bus interface, eliminating the need for a PCIe slot. For portable devices where the display outputs are "Portable Device Dependent," the integrated GPU offers a zero-footprint solution.

The data indicates a clear use-case split. The Arc Pro B65 targets professional workstations with dedicated graphics requirements. The UHD Graphics 770 Mobile serves everyday computing on mobile platforms where basic display output and light acceleration suffice. Benchmark wins are unrecorded, but the specification sheet assigns every performance-oriented metric to the Arc Pro B65 by wide margins.

Architecture Differences

The two GPUs come from completely different architectural lineages. The Arc Pro B65 uses the BMG-G21 chip built on the Xe2-HPG architecture, part of the Battlemage (Pro Series) generation. It is fabricated on a 5 nm process at TSMC, containing 19,600 million transistors on a 272 mm² die. Transistor density reaches 72.1M per mm², a figure typical of advanced foundry nodes.

The UHD Graphics 770 Mobile uses the Raptor Lake chip based on Generation 12.2 architecture, belonging to the HD Graphics-M (Raptor Lake) generation. It is built on Intel's 10 nm process. The database records no transistor count, die size, or transistor density for this part, reflecting its integrated nature within a larger processor die.

The Arc Pro B65 supports DirectX 12 Ultimate (12_2), while the UHD Graphics 770 Mobile supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The Arc Pro B65's newer architecture includes dedicated ray tracing hardware (20 RT cores), whereas the integrated part has none. The Xe2-HPG architecture also brings a 2:1 FP16 ratio, allowing the Arc Pro B65 to double its FP32 throughput in half-precision workloads. The UHD Graphics 770 Mobile also lists a 2:1 FP16 ratio, but at vastly lower absolute numbers.

The production status for both is Active, though the UHD Graphics 770 Mobile has a recorded successor: Arc Graphics-M. The Arc Pro B65 lists no predecessor or successor in the database. Release dates differ significantly: the UHD Graphics 770 Mobile launched on 2023-01-03, while the Arc Pro B65 launched on 2026-03-31. That three-year gap explains the architectural advance between Generation 12.2 and Xe2-HPG.
