AMD Radeon 780M vs Intel Arc Pro B60 Dual Comparison

The AMD Radeon 780M and the Intel Arc Pro B60 Dual occupy opposite ends of the graphics spectrum, one an integrated processor for thin-and-light systems, the other a professional add-in board with substantial memory and power. The data available in the database shows a clear separation in purpose, capability, and measured performance, with the comparison hinging almost entirely on how each product is deployed.

Where Each One Wins

The AMD Radeon 780M is an integrated graphics processor (IGP) built into the Phoenix chip, designed for systems where a discrete GPU is absent. Its entire operating envelope is defined by the host system: memory is System Shared, bandwidth is System Dependent, and display outputs are Motherboard Dependent. This makes it the only option in the comparison for ultra-portable or low-power designs where a dedicated card cannot physically fit. The 780M carries a 15 W TDP and uses no power connectors, meaning it functions entirely off the motherboard's existing power delivery. Its wins are structural: it exists where the Intel Arc Pro B60 Dual cannot.

The Intel Arc Pro B60 Dual is a dual-slot, 300 mm long card with a 400 W TDP and a suggested 800 W power supply. It brings 24 GB of dedicated GDDR6 memory on a 192-bit bus with 456.0 GB/s of bandwidth, none of which depends on the host system's RAM. It is the clear winner in scenarios requiring large local memory pools, sustained throughput, and professional display connectivity with 4x mini-DisplayPort 2.1 outputs. The Arc Pro B60 Dual also wins on raw compute ceilings, with 12.29 TFLOPS FP32 versus the 780M's 8.909 TFLOPS, and delivers 24.58 TFLOPS FP16, double its own FP32 rate, while the 780M is capped at 8.909 TFLOPS FP16 (1:1).

Architecture Differences

The two parts come from different foundries and use different process nodes. The AMD Radeon 780M is built on TSMC's 4 nm process and packs 25,390 million transistors into a 178 mm² die, yielding a transistor density of 142.6M per mm². The Intel Arc Pro B60 Dual uses TSMC's 5 nm node with 19,600 million transistors on a larger 272 mm² die, resulting in a lower density of 72.1M per mm². The 780M is denser, but the Arc Pro B60 Dual physically has more silicon area to work with.

Architecturally, they diverge completely. The 780M uses RDNA 3.0 from the Navi III IGP generation, while the Arc Pro B60 Dual uses Xe2-HPG from the Battlemage Pro Series. The 780M has 768 shading units, 48 texture mapping units, and 32 ROPs, paired with 12 ray tracing cores. The Arc Pro B60 Dual has 2560 shading units, 160 TMUs, and 80 ROPs, with 20 ray tracing cores. That is more than triple the shading units and over triple the TMUs and ROPs on the Intel side.

Clock behavior differs as well. The 780M has a base clock of 800 MHz and boosts to 2900 MHz. The Arc Pro B60 Dual starts at 2000 MHz and boosts to 2400 MHz. Despite a lower peak boost, the Intel part's higher base clock and vastly wider execution resources produce higher fill rates: 192.0 GPixel/s pixel rate and 384.0 GTexel/s texture rate versus 92.80 GPixel/s and 139.2 GTexel/s on the 780M. The memory subsystem is the other major divide. The 780M relies entirely on system RAM with no dedicated VRAM, while the Arc Pro B60 Dual uses 24 GB GDDR6 at 2375 MHz with 19 Gbps effective speed over a 192-bit bus.

The interface and physical requirements follow the same pattern. The 780M uses PCIe 4.0 x8 and is an IGP with no slot width, no power connectors, and no dimensions listed. The Arc Pro B60 Dual uses PCIe 5.0 x8, is a dual-slot card measuring 300 mm by 110 mm by 40 mm, and requires a single 16-pin power connector. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the API feature set is identical.

Head-to-Head Benchmarks

Direct comparison data is limited because the database contains no head-to-head benchmark entries and the Intel Arc Pro B60 Dual has no recorded benchmark scores, giving it an average benchmark score of 0. The AMD Radeon 780M, by contrast, has three recorded results. In 3dmark_3dmark_steel_nomad_dx12, it scores 480. In geekbench_opencl, it scores 18602. In geekbench_vulkan, it scores 33683. Its average benchmark score is 17588, placing it in the 61st percentile of all GPUs.

The nearest rivals for the 780M put its position in context. The AMD Radeon Pro 560 averages 17551, a delta of 0.2% behind. The NVIDIA GeForce RTX 4060 averages 17639, a delta of -0.3% ahead. The AMD Radeon HD 7790 averages 17666, a delta of -0.4% ahead. The AMD Radeon Pro 460 averages 17509, a delta of 0.5% behind. The 780M sits essentially at parity with a very tight cluster of older and newer discrete cards, all within half a percent of each other. This suggests that, for its integrated nature, the 780M delivers compute performance comparable to those specific products.

With no benchmark records for the Arc Pro B60 Dual, the database cannot produce a measured head-to-head score. The comparison rests on architectural specifications and the absence of verified results. The 780M's recorded scores show it performing near the RTX 4060 and the HD 7790, both of which are discrete cards, but the Arc Pro B60 Dual's specifications indicate a different performance class entirely. The 780M's FP32 of 8.909 TFLOPS is lower than the Arc Pro B60 Dual's 12.29 TFLOPS, and the Intel part has more than three times the shading units. The 780M cannot match the memory bandwidth either: its bandwidth is listed as System Dependent, whereas the Arc Pro B60 Dual has a fixed 456.0 GB/s.

The Verdict

The data points to a straightforward conclusion: these are not competing products. The AMD Radeon 780M is an integrated solution for systems with no discrete graphics, drawing 15 W and relying on shared system memory. Its recorded benchmarks show it performing in the same vicinity as the Radeon Pro 560, the RTX 4060, the HD 7790, and the Radeon Pro 460, which is notable for an IGP. The Intel Arc Pro B60 Dual is a professional dual-slot card with a 400 W TDP, 24 GB of dedicated GDDR6, and a suggested 800 W power supply. It offers no benchmark scores in the database, so its measured performance is currently unverified, but its architecture and memory configuration place it in a different tier.

From the recorded data alone, the 780M is the only one of the two with measurable performance. From the architectural data, the Arc Pro B60 Dual has the higher compute ceiling, the larger memory pool, and the dedicated bandwidth. The 780M is the choice for integrated, low-power designs; the Arc Pro B60 Dual is the choice for workloads requiring 24 GB of VRAM and high sustained throughput. The database records the 780M at the 61st percentile of all GPUs, while the Arc Pro B60 Dual sits at the 50th percentile with an average score of 0, reflecting its lack of recorded results rather than its capability.
