The Verdict

The data describes two products at opposite ends of the GPU spectrum. The AMD Radeon 780M is an integrated processor solution with a 15 W TDP, designed to share system memory and operate within a laptop or compact platform. Its benchmark results show a functional level of performance, with an average score of 17588 and a percentile rank of 61 against all GPUs.

The Intel Arc Pro B70 is a discrete, dual-slot add-in board with a 230 W TDP, 32 GB of dedicated GDDR6 memory, and a suggested power supply of 550 W. It carries a launch MSRP of 949 USD. However, its benchmark array is empty, so no measured performance data exists in the database to compare directly with the 780M.

The choice between these two rests entirely on platform and workload. For systems that need an integrated solution with minimal power draw, the 780M is the only option that fits. For a workstation or prosumer build that requires a large dedicated memory pool and high compute throughput, the Arc Pro B70 is the intended candidate, but its actual benchmark scores remain unverified in the recorded data.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two GPUs. The AMD Radeon 780M has three recorded test scores: 480 in 3DMark Steel Nomad DX12, 18602 in Geekbench OpenCL, and 33683 in Geekbench Vulkan. These results feed into its average of 17588.

The Intel Arc Pro B70 has no benchmark scores listed, so there are no exact numerical comparisons to walk through. The only measurable comparisons available come from the specification fields, which show the Arc Pro B70 with higher raw compute ceilings and a dedicated memory subsystem.

The 780M's nearest rival data provides context for its performance tier. It sits nearly level with the AMD Radeon Pro 560 (17551, 0.2% ahead) and the AMD Radeon Pro 460 (17509, 0.5% ahead). It trails the AMD Radeon HD 7790 (17666) by 0.4% and the NVIDIA GeForce RTX 4060 (17639) by 0.3%. This places the 780M in a tight cluster of mid-range performers, despite being an integrated part.

Without any recorded scores for the Arc Pro B70, the benchmark comparison must remain incomplete. The specification sheet suggests a substantial performance gap, but the database cannot confirm it with measured results.

Specification Differences

The two GPUs differ across nearly every hardware field. The AMD Radeon 780M uses a 4 nm process node from TSMC with 25,390 million transistors on a 178 mm² die. The Intel Arc Pro B70 uses a 5 nm process node from TSMC with a 368 mm² die, while its transistor count is listed as unknown.

Clock behavior differs sharply. The 780M has a base clock of 800 MHz and a boost clock of 2900 MHz. The Arc Pro B70 has a base clock of 2280 MHz and a boost clock of 2800 MHz. Despite the lower boost, the Arc Pro B70 runs a much higher base clock.

Memory is the largest split. The 780M uses system-shared memory with a system-dependent bus width and bandwidth. The Arc Pro B70 uses 32 GB of GDDR6 on a 256-bit bus with 608.0 GB/s of bandwidth.

Compute resources also differ. The 780M has 768 shading units, 48 texture mapping units, and 32 render output units. The Arc Pro B70 has 4096 shading units, 256 TMUs, and 128 ROPs. The 780M includes 12 ray tracing cores, while the Arc Pro B70 includes 32.

Pixel and texture rates follow the same pattern. The 780M outputs 92.80 GPixel/s and 139.2 GTexel/s. The Arc Pro B70 outputs 358.4 GPixel/s and 716.8 GTexel/s.

FP16 compute also diverges. The 780M provides 8.909 TFLOPS with a 1:1 ratio to FP32. The Arc Pro B70 provides 45.88 TFLOPS with a 2:1 ratio, indicating a dedicated path for half-precision work.

Power delivery differs completely. The 780M is an IGP with no power connectors and a 15 W TDP. The Arc Pro B70 is a dual-slot card with one 8-pin connector, a 230 W TDP, and a suggested PSU of 550 W.

The bus interface also differs. The 780M uses PCIe 4.0 x8, while the Arc Pro B70 uses PCIe 5.0 x16. Display outputs on the 780M are motherboard dependent, while the Arc Pro B70 provides one HDMI 2.1a and three DisplayPort 2.1 outputs.

Architecture Differences

The AMD Radeon 780M is built on RDNA 3.0 architecture and belongs to the Navi III IGP generation with the Phoenix chip. Its process node is 4 nm, produced by TSMC, and it uses 25,390 million transistors. The architecture targets integrated use cases, sharing system memory and relying on the host platform for output and power delivery.

The Intel Arc Pro B70 is built on Xe2-HPG architecture and belongs to the Battlemage Pro Series generation with the BMG-G31 chip. Its process node is 5 nm, also produced by TSMC. The die size is 368 mm², which is more than double the 178 mm² die of the 780M, though the transistor count is not recorded.

Both products support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level features align. The architectural differences lie in execution resources and memory handling. The RDNA 3.0 design uses a smaller shading array and a 1:1 FP16 to FP32 ratio, suggesting a simpler compute path. The Xe2-HPG design uses a much larger shading array and a 2:1 FP16 ratio, which points to a more capable half-precision throughput.

The 780M integrates 12 ray tracing cores, while the Arc Pro B70 includes 32. The larger die and dedicated GDDR6 subsystem on the Arc Pro B70 indicate a design intended for sustained, high-throughput workloads rather than power-constrained integrated operation.

Where Each One Wins

The AMD Radeon 780M wins in power efficiency and platform flexibility. Its 15 W TDP, IGP form factor, and lack of power connectors make it suitable for systems where discrete power delivery is unavailable. Its PCIe 4.0 x8 interface and motherboard-dependent outputs fit compact designs. Its 4 nm process node and 25,390 million transistor count show a dense, modern integrated design.

The Intel Arc Pro B70 wins in raw specification ceilings. Its 22.94 TFLOPS FP32, 45.88 TFLOPS FP16, 608.0 GB/s bandwidth, and 32 GB of GDDR6 memory place it in a different performance class on paper. The 358.4 GPixel/s pixel rate and 716.8 GTexel/s texture rate are substantially higher than the 780M's 92.80 GPixel/s and 139.2 GTexel/s. The 256 TMUs and 128 ROPs more than quadruple the 780M's texture and render output capacity.

The 780M wins in the benchmark database because it has recorded scores. Its percentile rank of 61 and average score of 17588 give it a measurable position. The Arc Pro B70 has no recorded scores and an average of 0, so its percentile of 50 is not supported by any test data.

The Arc Pro B70 wins on memory capacity and bandwidth. A 32 GB GDDR6 pool with 608.0 GB/s is a workstation-class configuration, while the 780M depends entirely on system memory. The Arc Pro B70 also wins on connectivity, with dedicated display outputs and a PCIe 5.0 x16 interface.

The 780M wins on release timing and production status. It was released on 2024-01-30 and is marked Active. The Arc Pro B70 has a recorded release date of 2026-03-25 and a null production status, leaving its availability unclear.

For compute-heavy tasks that fit within an integrated power budget, the 780M is the only data-supported option. For tasks that require the Arc Pro B70's specification sheet, the lack of benchmark scores means its real-world standing cannot be verified from the database.
