AMD Radeon 880M vs Intel Arc Pro B70 Comparison

Head-to-Head Benchmarks

The database contains a complete benchmark record for the AMD Radeon 880M, spanning ten separate tests across DirectX 9, 10, 11, and 12, OpenCL, Vulkan, and general 2D and 3D workloads. The Intel Arc Pro B70, by contrast, has no recorded benchmark scores in the database at the time of this analysis. This makes a direct score-by-score comparison impossible, but the available data still provides a meaningful picture of where the 880M stands and what the Arc Pro B70's specifications imply.

The Radeon 880M's strongest results come from compute-oriented workloads. In Geekbench Vulkan, it scores 40,006, and in Geekbench OpenCL it records 31,285. These numbers place the integrated GPU well ahead of its peer group in synthetic compute tests. Its PassMark G3D score of 7,615 and PassMark GPU Compute score of 3,719 reinforce this pattern, showing that the 880M handles general-purpose GPU workloads better than legacy rasterization tasks.

The 880M's legacy DirectX results are comparatively modest. It scores 97 in PassMark DirectX 9, 73 in DirectX 11, 32 in DirectX 12, and 31 in DirectX 10. The PassMark G2D score of 969 indicates solid 2D performance for an integrated part. The 3DMark Steel Nomad DX12 score of 535 is the only modern DirectX 12 test recorded, and it sits well below what discrete GPUs typically achieve.

The average benchmark score for the Radeon 880M is 8,436, placing it at the 43rd percentile of all GPUs in the database. Its nearest rivals in average score are the NVIDIA GeForce GTX 675MX at 8,427 (0.1% behind the 880M), the NVIDIA GeForce MX330 at 8,458 (0.3% ahead), the AMD Radeon HD 8870M at 8,462 (0.3% ahead), and the AMD Radeon R9 M375X at 8,325 (1.3% behind). This clustering shows the 880M performs in the same range as older mid-range discrete mobile GPUs, despite being an integrated solution.

The Arc Pro B70 has no benchmark scores recorded, so its average score is listed as 0 and its percentile is 50, which appears to be a placeholder rather than a measured result. The absence of test data means any performance comparison relies entirely on architectural specifications and the 880M's measured results.

Architecture Differences

The two GPUs come from different manufacturers and use fundamentally different designs. The AMD Radeon 880M is built on the RDNA 3.5 architecture, fabricated on a 4 nm process at TSMC. It uses the Strix Point chip and belongs to the Navi III IGP generation. The Intel Arc Pro B70 uses the Xe2-HPG architecture, fabricated on a 5 nm process also at TSMC, with the BMG-G31 chip from the Battlemage Pro Series generation.

Process technology differs: the 880M uses 4 nm while the Arc Pro B70 uses 5 nm. The 880M integrates 34,000 million transistors on a 233 mm² die, giving a transistor density of 145.9 million per square millimeter. The Arc Pro B70's transistor count is listed as unknown, but its die size is 368 mm², substantially larger than the 880M's.

Shading resources differ by a wide margin. The 880M has 768 shading units, 48 texture mapping units (TMUs), 16 raster operations units (ROPs), and 12 ray tracing cores. The Arc Pro B70 has 4,096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. This represents a 5.3x difference in shading units, a 5.3x difference in TMUs, an 8x difference in ROPs, and a 2.7x difference in ray tracing cores, all favoring the Intel part.

Clock speeds tell a different story. The 880M has a base clock of 400 MHz and a boost clock of 2,900 MHz. The Arc Pro B70 has a base clock of 2,280 MHz and a boost clock of 2,800 MHz. The 880M's boost clock is higher, but its base clock is dramatically lower, reflecting the power envelope differences between an integrated GPU and a discrete card.

Memory architecture is entirely different. The 880M uses system-shared memory, with size, type, bus width, and bandwidth all listed as system dependent. The Arc Pro B70 has 32 GB of GDDR6 memory on a 256-bit bus, with a bandwidth of 608.0 GB/s and an effective memory clock of 19 Gbps. This gives the Intel card a massive memory advantage in both capacity and bandwidth.

Compute throughput follows the hardware resources. The 880M delivers 4.454 TFLOPS of FP32 performance and the same 4.454 TFLOPS for FP16, indicating a 1:1 ratio. The Arc Pro B70 delivers 22.94 TFLOPS of FP32 and 45.88 TFLOPS of FP16, a 2:1 ratio. The Intel card has roughly 5.2x the FP32 throughput and 10.3x the FP16 throughput.

Pixel and texture rates scale accordingly. The 880M achieves 46.40 GPixel/s pixel rate and 139.2 GTexel/s texture rate. The Arc Pro B70 achieves 358.4 GPixel/s and 716.8 GTexel/s, representing 7.7x and 5.1x advantages respectively.

Power and physical specifications diverge sharply. The 880M has a TDP of 15 W, is an IGP with no power connectors, and uses a PCIe 4.0 x8 interface. The Arc Pro B70 has a TDP of 230 W, is a dual-slot card with a single 8-pin power connector, requires a 550 W suggested PSU, and uses a PCIe 5.0 x16 interface. The Arc Pro B70 measures 267 mm in length, 110 mm in height, and 39 mm in width.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The 880M's display outputs are listed as portable device dependent, while the Arc Pro B70 has 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs.

Where Each One Wins

Based on the recorded data, the Radeon 880M wins in scenarios where power efficiency and integration matter. Its 15 W TDP means it can operate in thin-and-light portable devices without additional cooling or power delivery. The 880M's Geekbench Vulkan score of 40,006 and OpenCL score of 31,285 show it handles compute workloads respectably for an integrated part, and its PassMark G3D score of 7,615 indicates it can manage light 3D rendering tasks.

The Arc Pro B70 wins on raw specification across every compute and graphics metric. Its 22.94 TFLOPS FP32 throughput, 608.0 GB/s memory bandwidth, and 32 GB of GDDR6 memory place it in an entirely different performance class. The 32 ray tracing cores and 4,096 shading units suggest strong modern game and professional rendering performance, though the database lacks measured scores to confirm this.

For legacy DirectX workloads, the 880M's recorded scores (97 in DX9, 73 in DX11, 32 in DX12, 31 in DX10) indicate it can run older titles but will struggle with demanding modern games. The Arc Pro B70's architecture supports DirectX 12 Ultimate, so it should handle the full range of DX12 features, but no direct comparison data exists.

The 880M suits systems where the GPU must share power and thermal budget with a CPU. The Arc Pro B70 suits workstations or desktops where a dedicated card with its own cooling and power delivery is acceptable. The Arc Pro B70's PCIe 5.0 x16 interface provides higher host bandwidth than the 880M's PCIe 4.0 x8, which matters for data-intensive professional workloads.

The release dates differ by roughly twenty months, with the 880M launching in July 2024 and the Arc Pro B70 in March 2026. The Arc Pro B70 carries a launch MSRP of 949 USD, while the 880M has no MSRP listed because it is an integrated GPU sold as part of a mobile platform.

The Verdict

The data shows two GPUs designed for completely different roles. The AMD Radeon 880M is an integrated processor built into a mobile chip, consuming 15 W and sharing system memory. Its measured performance clusters with older discrete mobile GPUs: it sits within 0.3% of the NVIDIA GeForce MX330 and AMD Radeon HD 8870M, and 1.3% ahead of the AMD Radeon R9 M375X. The 880M's 43rd percentile ranking and 8,436 average score indicate it performs adequately for an IGP but does not compete with modern discrete cards.

The Intel Arc Pro B70 is a discrete add-in card with 32 GB of dedicated GDDR6 memory, 608.0 GB/s bandwidth, and 22.94 TFLOPS FP32 throughput. Its 230 W TDP, dual-slot cooler, and 550 W suggested PSU place it firmly in the high-end workstation or enthusiast desktop segment. The launch MSRP of 949 USD reflects this positioning. The lack of benchmark scores means its real-world performance cannot be verified from the database, but its specifications indicate it should handle demanding professional rendering, ray tracing, and compute workloads far beyond the 880M's capacity.

For a thin-and-light laptop where the GPU must share power with the CPU, the 880M is the only sensible choice, and its recorded compute scores show it can handle light productivity and legacy gaming. For a desktop workstation requiring maximum throughput, dedicated memory, and professional display outputs, the Arc Pro B70's specifications point to substantially higher capability, though measured confirmation is pending. The choice between the two is not a performance question but a form-factor question: one is an integrated component, the other is a standalone card with its own power and cooling requirements.
