AMD Radeon 780M vs Intel Arc Pro B370 Comparison

Head-to-Head Benchmarks

The benchmark comparison between the AMD Radeon 780M and the Intel Arc Pro B370 is defined by a stark data asymmetry. The AMD Radeon 780M has three recorded benchmark scores in the database, while the Intel Arc Pro B370 has no recorded benchmark scores at all. Consequently, all head-to-head numerical comparisons rely entirely on the AMD part's measured performance and the Intel part's architectural specifications.

In the 3DMark Steel Nomad DX12 test, the AMD Radeon 780M records a score of 480. This is the only dedicated graphics workload score available for either part. For compute-oriented workloads, the AMD Radeon 780M delivers a Geekbench OpenCL score of 18,602 and a Geekbench Vulkan score of 33,683. The absence of any benchmark entries for the Intel Arc Pro B370 means no direct score comparison is possible. The database shows zero wins for each part in the head-to-head field, reflecting the lack of matching test data.

The AMD Radeon 780M holds an average benchmark score of 17,588 across its recorded tests. This places it at the 61st percentile among all GPUs in the database.

Where Each One Wins

The AMD Radeon 780M wins in every category where measured data exists. Its FP32 throughput of 8.909 TFLOPS exceeds the Intel Arc Pro B370's 6.144 TFLOPS by a substantial margin. The pixel rate also favors AMD, with 92.80 GPixel/s versus 48.00 GPixel/s for Intel. Texture rate follows the same pattern: 139.2 GTexel/s for the AMD part versus 96.00 GTexel/s for the Intel part. The AMD Radeon 780M also has more render output units, 32 versus 20, and more texture mapping units, 48 versus 40.

The Intel Arc Pro B370 wins on shading unit count, with 1,280 shading units versus 768 for the AMD part. The Intel part also has a higher FP16 throughput at 12.29 TFLOPS (2:1 ratio) compared to the AMD part's 8.909 TFLOPS (1:1 ratio). This means the Intel part can process half-precision floating point calculations faster than the AMD part, which is relevant for workloads that leverage FP16 arithmetic. The Intel part also has a slightly higher TDP at 25 W versus 15 W, indicating it is designed to draw more power.

The compute ratio difference is notable. The AMD Radeon 780M maintains a 1:1 ratio between FP16 and FP32, while the Intel Arc Pro B370 uses a 2:1 ratio. For software that can utilize FP16 instructions, the Intel part's architecture provides double the half-precision throughput relative to its FP32 capability. For the AMD part, FP16 performance equals FP32 performance, meaning there is no throughput advantage when switching to half-precision.

Specification Differences

The two GPUs differ across several core specification fields. The AMD Radeon 780M uses the Phoenix chip, while the Intel Arc Pro B370 uses the Panther Lake chip. The process nodes differ: the AMD part is built on a 4 nm process by TSMC, and the Intel part is built on a 3 nm process by Intel. The transistor count is listed as 25,390 million for the AMD part, while the Intel part's transistor count is unknown. The die size for the AMD part is 178 mm², with a transistor density of 142.6M per mm². The Intel part's die size and transistor density are unknown.

Clock speeds show clear differences. The AMD Radeon 780M has a base clock of 800 MHz and a boost clock of 2900 MHz. The Intel Arc Pro B370 has a base clock of 300 MHz and a boost clock of 2400 MHz. The AMD part's base clock is more than double the Intel part's base clock.

The bus interface differs. The AMD Radeon 780M uses PCIe 4.0 x8, while the Intel Arc Pro B370 uses IGP. The display outputs also differ: the AMD part uses Motherboard Dependent outputs, and the Intel part uses Portable Device Dependent outputs.

The TDP values differ, with the AMD part rated at 15 W and the Intel part at 25 W. Both use System Shared memory with System Shared memory type, bus width, and System Dependent bandwidth. Both have no power connectors and an IGP slot width.

The release dates are far apart. The AMD Radeon 780M was released on 2024-01-30, and the Intel Arc Pro B370 was released on 2026-01-26. The AMD part's predecessor is listed as Navi II IGP and successor as Navi III IGP. The Intel part's predecessor is HD Graphics-WM, with no successor listed.

Architecture Differences

The architectural divide between these two parts is substantial. The AMD Radeon 780M uses RDNA 3.0 architecture, belongs to the Navi III IGP generation, and is built on a 4 nm TSMC process. The Intel Arc Pro B370 uses Xe3-LPG architecture, belongs to the Arc Graphics-WM generation, and is built on a 3 nm Intel process. These are fundamentally different GPU architectures from different manufacturers, targeting different integration scenarios.

The core configurations diverge in several ways. The AMD part has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores. The Intel part has 1,280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. Despite having fewer shading units, the AMD part achieves higher pixel rate, texture rate, and FP32 throughput. This indicates the AMD architecture extracts more work per shading unit in these measured metrics, or the clock speed advantage of 2900 MHz versus 2400 MHz plays a decisive role.

Neither part has tensor cores listed. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The API support is identical across both parts.

The memory architecture is shared for both, with System Shared memory and System Dependent bandwidth. This means both rely on system RAM rather than dedicated VRAM, a common trait for integrated graphics processors. The AMD part's memory clock is listed as System Shared, and the Intel part's memory clock is also System Shared. Neither has a dedicated memory bus width or bandwidth figure.

The FP16 capability differs in ratio. The AMD Radeon 780M achieves 8.909 TFLOPS in FP16 with a 1:1 ratio to FP32. The Intel Arc Pro B370 achieves 12.29 TFLOPS in FP16 with a 2:1 ratio to FP32. The Intel part's FP16 advantage is a direct result of its architecture supporting a dedicated half-precision path that doubles throughput relative to FP32.

The Verdict

The recorded data clearly favors the AMD Radeon 780M for established workloads. The AMD part has measurable performance in three benchmarks, an average score of 17,588, and a 61st percentile ranking. The Intel Arc Pro B370 has no recorded benchmarks, an average score of 0, and a 50th percentile ranking that reflects absence of data rather than measured performance. For any user relying on database results, the AMD Radeon 780M is the only part with verified performance evidence.

The AMD part also leads in raw throughput metrics. Its FP32 output of 8.909 TFLOPS, pixel rate of 92.80 GPixel/s, and texture rate of 139.2 GTexel/s all exceed the Intel part's corresponding figures of 6.144 TFLOPS, 48.00 GPixel/s, and 96.00 GTexel/s. The AMD part's higher boost clock of 2900 MHz versus 2400 MHz, and its higher base clock of 800 MHz versus 300 MHz, support these performance advantages.

The Intel Arc Pro B370's case rests on architectural headroom rather than measured results. Its 1,280 shading units exceed the AMD part's 768, and its FP16 throughput of 12.29 TFLOPS is higher than the AMD part's 8.909 TFLOPS. The Intel part's 3 nm process node is also more advanced than the AMD part's 4 nm node. However, without benchmark scores, these specifications cannot be validated against real-world performance in the database.

Users should pick the AMD Radeon 780M for any scenario requiring verified performance data, established driver maturity, or higher FP32 throughput. Users should consider the Intel Arc Pro B370 for scenarios prioritizing shading unit count, FP16 compute throughput, or the newer 3 nm manufacturing process. The Intel part's 25 W TDP versus the AMD part's 15 W TDP suggests it is designed for a different power envelope, but the data does not indicate which workloads would benefit. The absence of any benchmark entries for the Intel Arc Pro B370 is the decisive factor: the AMD Radeon 780M is the only part in this comparison with demonstrated results.
