AMD Radeon 880M vs Intel Arc B370 Comparison

AMD Radeon 880M and Intel Arc B370 are both integrated graphics processors, but the recorded data shows they occupy very different performance tiers. The AMD 880M is based on the Strix Point chip with RDNA 3.5 architecture, while the Intel Arc B370 uses the Panther Lake chip with Xe3-LPG architecture. Both are active production parts, with the AMD releasing earlier and the Intel following later. The benchmark database contains a single shared test between the two, the 3DMark Steel Nomad DX12 workload, and the results are decisively one-sided.

Head-to-Head Benchmarks

The only direct comparison available in the database is the 3DMark Steel Nomad DX12 test. In this workload, the Intel Arc B370 scores 1184, while the AMD Radeon 880M scores 535. The Intel part leads by 649 points, which translates to a performance advantage of 54.8 percent over the AMD competitor. This is not a marginal gap; it is a dominant margin that places the two products in entirely separate performance brackets.

Looking at the average benchmark scores from the full database, the picture becomes more complex. The AMD Radeon 880M has an average benchmark score of 8436, derived from ten separate tests covering DirectX 9, DirectX 10, DirectX 11, DirectX 12, OpenCL, Vulkan, GPU compute, and 2D workloads. The Intel Arc B370 has only one recorded benchmark, the 3DMark Steel Nomad result, giving it an average score of 1184. This disparity in available data means the average scores are not directly comparable, but the single shared test is unambiguous.

The percentile rankings further illustrate the divide. The AMD Radeon 880M sits at the 43rd percentile among all GPUs in the database, meaning it outperforms roughly 43 percent of recorded graphics hardware. The Intel Arc B370, however, sits at only the 5th percentile, indicating it outperforms just 5 percent of all GPUs. Despite winning the head-to-head test decisively, the Intel part ranks far lower overall because its single benchmark result places it near the bottom of the database hierarchy.

The nearest rivals for each product confirm the separation. The AMD Radeon 880M's closest competitors include the NVIDIA GeForce GTX 675MX with an average score of 8427 (a 0.1 percent difference), the NVIDIA GeForce MX330 at 8458 (a 0.3 percent difference in favor of the NVIDIA), and the AMD Radeon HD 8870M at 8462 (also 0.3 percent ahead). The AMD Radeon R9 M375X trails at 8325, putting the 880M 1.3 percent ahead. These are all older discrete mobile GPUs, and the 880M essentially trades blows with them.

For the Intel Arc B370, the nearest rivals are all much older parts. The ATI Mobility Radeon HD 5570 scores 1186 (0.2 percent ahead of the Arc), the ATI Radeon HD 5770 scores 1190 (0.5 percent ahead), and the AMD Radeon HD 7650M scores 1192 (0.7 percent ahead). The AMD FirePro M2000 trails at 1168, putting the Arc B370 1.4 percent ahead. These are legacy discrete GPUs from over a decade ago, and the Arc B370's performance is essentially equivalent to them in the recorded data.

The delta percentages in the head-to-head section show only one recorded comparison, with the Intel Arc B370 winning. The database records zero wins for the AMD Radeon 880M and one win for the Intel Arc B370 in direct comparisons. However, the AMD part has a much broader benchmark footprint, with ten recorded tests, while the Intel part has just one. This means the AMD 880M has demonstrated performance across a wider range of workloads, whereas the Intel Arc B370's capabilities are only documented for a single DX12 test.

Architecture Differences

The two integrated GPUs come from different manufacturers and use fundamentally different architectures. The AMD Radeon 880M is built on the Strix Point chip with RDNA 3.5 architecture, part of the Navi III IGP generation for mobile Strix Point processors. It is manufactured on a 4 nm process at TSMC, with a die size of 233 mm² and 34,000 million transistors. The transistor density works out to 145.9 million transistors per square millimeter.

The Intel Arc B370 uses the Panther Lake chip with Xe3-LPG architecture, belonging to the Arc Graphics-M generation for Panther Lake processors. It is manufactured on a 3 nm process at Intel, but the database lists the transistor count and die size as unknown, with no transistor density recorded. This makes a direct comparison of manufacturing complexity impossible from the available data.

The compute units differ significantly. The AMD Radeon 880M has 768 shading units, 48 texture mapping units, and 16 raster operations pipelines. It also includes 12 ray tracing cores. The Intel Arc B370 has 1280 shading units, which is 512 more than the AMD part, but only 40 texture mapping units and 20 raster operations pipelines. The Intel part has 10 ray tracing cores, two fewer than the AMD.

Clock speeds show the AMD part running faster. The AMD Radeon 880M has a base clock of 400 MHz and a boost clock of 2900 MHz. The Intel Arc B370 has a base clock of 300 MHz and a boost clock of 2400 MHz. The AMD part boosts 500 MHz higher, which partially compensates for its lower shading unit count.

Memory configurations are identical in type, with both using system shared memory. The memory size, bus width, and bandwidth are all listed as system dependent for both parts. Neither GPU has dedicated VRAM, and both rely on the host system's memory allocation.

The thermal design power differs, with the AMD Radeon 880M rated at 15 W and the Intel Arc B370 rated at 25 W. The Intel part draws more power, which may explain its higher benchmark score but also indicates higher energy consumption. Both are integrated graphics processors with no power connectors and no suggested PSU.

The bus interfaces differ. The AMD Radeon 880M uses PCIe 4.0 x8, while the Intel Arc B370 is listed simply as IGP. Display outputs for both are portable device dependent, meaning they vary based on the laptop or handheld system they are integrated into.

API support is identical. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Neither has tensor cores listed in the database.

Floating point performance favors the Intel part. The AMD Radeon 880M delivers 4.454 TFLOPS for FP32 and 4.454 TFLOPS for FP16 with a 1:1 ratio. The Intel Arc B370 delivers 6.144 TFLOPS for FP32 and 12.29 TFLOPS for FP16 with a 2:1 ratio. The Intel part is 38 percent ahead in FP32 and nearly three times ahead in FP16.

Texture and pixel rates split the difference. The AMD Radeon 880M has a texture rate of 139.2 GTexel/s, which is higher than the Intel Arc B370's 96.00 GTexel/s. However, the Intel part has a pixel rate of 48.00 GPixel/s, slightly ahead of the AMD part's 46.40 GPixel/s.

The Verdict

The recorded data indicates that the Intel Arc B370 is the stronger performer in the single direct benchmark available. The 3DMark Steel Nomad DX12 score of 1184 versus 535 represents a 54.8 percent lead, which is a substantial margin. If the only criterion is this specific DX12 workload, the Intel Arc B370 is the clear choice.

However, the broader database context complicates this verdict. The AMD Radeon 880M has an average benchmark score of 8436 across ten tests, placing it at the 43rd percentile of all GPUs. The Intel Arc B370 has an average score of 1184 from one test, placing it at the 5th percentile. These percentile figures suggest that, in the context of all recorded GPUs, the AMD part is much more competitive. The Intel Arc B370's nearest rivals are all ancient ATI and AMD parts from the HD 5000 and HD 7000 series, while the AMD Radeon 880M's nearest rivals are more recent NVIDIA and AMD mobile GPUs.

The power envelope favors the AMD part. At 15 W, the Radeon 880M uses 40 percent less power than the Intel Arc B370's 25 W. For integrated graphics in portable devices, this difference could be significant for battery life and thermal management. The AMD part also has a higher boost clock, reaching 2900 MHz compared to the Intel's 2400 MHz, and a higher texture rate.

For users prioritizing raw DX12 benchmark performance, the Intel Arc B370 delivers a higher score. For users considering overall GPU capability, broader workload coverage, and power efficiency, the AMD Radeon 880M has a stronger recorded profile. The database shows only one shared test, so conclusions beyond that test are limited by the available data.

Specification Differences

The two GPUs differ across nearly every recorded specification. The AMD Radeon 880M uses a 4 nm TSMC process with 34,000 million transistors on a 233 mm² die, while the Intel Arc B370 uses a 3 nm Intel process with unknown transistor count and die size. The AMD part has a transistor density of 145.9 million per square millimeter, while no density is recorded for the Intel part.

Where Each One Wins

The Intel Arc B370 wins in the only direct benchmark test, the 3DMark Steel Nomad DX12 workload. It also wins in raw compute specifications: more shading units, higher FP32 performance, much higher FP16 performance, and a higher pixel rate. Its 1280 shading units give it a theoretical compute advantage that appears to manifest in the DX12 test.

The AMD Radeon 880M wins in power efficiency, with a 15 W TDP compared to 25 W for Intel. It wins in texture rate, delivering 139.2 GTexel/s versus Intel's 96.00 GTexel/s. It has more ray tracing cores (12 versus 10), a higher boost clock (2900 MHz versus 2400 MHz), and a higher base clock (400 MHz versus 300 MHz). It also has a much broader benchmark footprint, with ten recorded tests spanning multiple API generations and compute workloads.

For workloads that stress FP16 compute, the Intel Arc B370 has a clear theoretical edge at 12.29 TFLOPS. For workloads that stress texture throughput, the AMD Radeon 880M has the advantage. For ray tracing workloads, the AMD part has two additional ray tracing cores. For power-constrained portable devices, the AMD part consumes less power.

The database records one win for Intel and zero for AMD in direct comparisons. However, the AMD part's average benchmark score of 8436, which is over seven times higher than Intel's 1184, suggests that the AMD part performs better across the broader range of tested workloads, even though only one test is shared between the two. The Intel Arc B370 appears specialized for high DX12 performance at higher power, while the AMD Radeon 880M appears more balanced across multiple workload types within a lower power budget.
