Intel Arc Graphics 64EU vs Intel Arc Pro B70 Comparison

The Verdict

The database comparison between the Intel Arc Graphics 64EU and the Intel Arc Pro B70 is a study in extremes. The integrated Arc Graphics 64EU is a low-power, low-throughput part designed for basic rendering tasks within Arrow Lake-S processors, while the Arc Pro B70 is a dedicated, high-performance workstation card built on a newer architecture with vastly superior resources. The data shows that the Arc Pro B70 delivers approximately 11.8 times the FP32 compute throughput of the Arc Graphics 64EU and offers 32 GB of dedicated GDDR6 memory, whereas the 64EU relies entirely on system shared memory. For any task where raw rendering performance matters, the Arc Pro B70 is the clear choice. For systems where power consumption and physical footprint are the primary constraints, the Arc Graphics 64EU remains a functional integrated option, but it occupies the lowest percentile of all GPUs in the database. The verdict is unambiguous: the Arc Pro B70 is for professional graphics workloads, and the Arc Graphics 64EU is for basic display output and lightweight acceleration.

Where Each One Wins

The Arc Graphics 64EU wins in power efficiency and physical integration. Its 65 W TDP is 165 W lower than the Arc Pro B70's 230 W TDP. It occupies no slot width, functioning as an IGP, whereas the Arc Pro B70 is a dual-slot card measuring 267 mm in length. The integrated part requires no power connectors, while the Arc Pro B70 needs a single 8-pin connector and a 550 W suggested PSU. The 64EU is also built on a more advanced 3 nm TSMC process node, compared to the 5 nm node of the Arc Pro B70, though this does little to overcome the massive resource deficit.

The Arc Pro B70 wins in every performance category. It has 4096 shading units versus 512, a 8x advantage. It offers 256 texture mapping units versus 32, an 8x advantage. It has 128 ROPs versus 16, an 8x advantage. It includes 32 ray tracing cores, while the 64EU has none recorded. Its pixel rate is 358.4 GPixel/s versus 30.40 GPixel/s, roughly 11.8x higher. Its texture rate is 716.8 GTexel/s versus 60.80 GTexel/s, also roughly 11.8x higher. FP32 throughput is 22.94 TFLOPS versus 1.946 TFLOPS, an 11.8x difference. The memory subsystem is entirely different: 32 GB of GDDR6 on a 256-bit bus with 608.0 GB/s bandwidth versus system shared memory with system dependent bandwidth. The Arc Pro B70 also uses a PCIe 5.0 x16 bus interface, while the 64EU relies on a Ring Bus. The Arc Pro B70 provides dedicated display outputs including 1x HDMI 2.1a and 3x DisplayPort 2.1, whereas the 64EU's outputs are motherboard dependent.

Architecture Differences

The two GPUs come from different Intel architectural generations. The Arc Graphics 64EU is based on the Xe-LPG architecture, part of the Arc Graphics (Arrow Lake) generation, and is built on a 3 nm TSMC process. The chip is Arrow Lake-S and contains 17,800 million transistors on a 243 mm² die, yielding a transistor density of 73.3M per mm². The Arc Pro B70 uses the Xe2-HPG architecture from the Battlemage (Pro Series) generation, built on a 5 nm TSMC process. Its chip is BMG-G31 with a 368 mm² die size, though transistor count is unknown. The newer Xe2-HPG architecture in the Arc Pro B70 introduces dedicated ray tracing cores, which are absent from the Xe-LPG based 64EU. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature support is identical. The clock behavior differs significantly: the Arc Graphics 64EU has a 300 MHz base clock and a 1900 MHz boost clock, while the Arc Pro B70 runs at a 2280 MHz base clock and a 2800 MHz boost clock. The Arc Pro B70's memory clock is 2375 MHz with 19 Gbps effective data rate. The 64EU's memory clock is listed as system shared, meaning it depends on the host system's RAM. The Arc Pro B70 is a discrete dual-slot card with a 267 mm length, 110 mm height, and 39 mm width. The Arc Graphics 64EU is an integrated part with no dimensions recorded. The Arc Pro B70 was released on 2026-03-25, while the Arc Graphics 64EU was released on 2024-10-23, making the Pro card roughly a year and a half newer.

Head-to-Head Benchmarks

Direct head-to-head benchmark data is not available in the database for these two products. The Arc Pro B70 has no recorded benchmark scores and no nearest rivals listed, while the Arc Graphics 64EU has a single 3DMark Steel Nomad DX12 score of 733. That score places the 64EU at the 3rd percentile of all GPUs, indicating extremely low overall performance. Its nearest rivals in the database are the Intel Arc Graphics 32EU and 24EU, both with identical average scores of 733 and a 0% delta, meaning the 64EU offers no measurable performance advantage over Intel's own lower-tier integrated graphics. The AMD Radeon HD 6470M scores 723, which is 1.4% below the 64EU, and the NVIDIA GeForce GT 415M scores 751, which is 2.4% above the 64EU. These rival comparisons show that the Arc Graphics 64EU sits in a performance band alongside decade-old discrete mobile GPUs and Intel's own entry-level integrated parts. The Arc Pro B70, by contrast, sits at the 50th percentile of all GPUs, a dramatic jump from the 64EU's 3rd percentile, even though no direct benchmark score is recorded for the Pro card. The absence of a recorded average benchmark score for the Arc Pro B70 means the percentile ranking is derived from its specifications rather than measured tests. The resource disparity between the two parts is so large that even without direct head-to-head results, the performance gap is well established by the compute, memory, and render output specifications.
