AMD Radeon 880M vs Intel Arc B770 Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Radeon 880M and Intel Arc B770 presents an unusual comparison scenario. The AMD Radeon 880M has a complete set of ten benchmark results across multiple test suites, while the Intel Arc B770 has no recorded benchmark scores in the database. This absence of data for the Intel part means the head-to-head comparison relies entirely on the AMD side's measurements and the architectural specifications of both products.

The AMD Radeon 880M posts an average benchmark score of 8436 across its recorded tests. Its percentile ranking of 43 places it below the median of all GPUs in the database. The strongest recorded result for the AMD part comes from the Geekbench Vulkan test, where it scores 40006. The Geekbench OpenCL result follows at 31285. These two scores indicate the integrated GPU's compute capabilities under different API environments.

In DirectX workloads, the Passmark results show a clear pattern. The DirectX 9 test produces a score of 97, which is the highest among the four DirectX variants recorded. The DirectX 11 test follows at 73, while DirectX 10 and DirectX 12 both score in the lower range at 31 and 32 respectively. This distribution suggests the AMD Radeon 880M delivers comparatively stronger performance in legacy DirectX 9 workloads than in more modern API paths.

The 3DMark Steel Nomad DX12 test yields a score of 535 for the AMD Radeon 880M. This result aligns with the Passmark DirectX 12 score of 32, both indicating modest performance in current-generation DirectX 12 titles. The Passmark G3D score of 7615 provides a composite gaming-oriented measurement, while the Passmark G2D score of 969 covers 2D desktop workloads. The GPU compute test records 3719.

The nearest rival data for the AMD Radeon 880M shows tight clustering. The NVIDIA GeForce GTX 675MX posts an average score of 8427, placing it 0.1 percent below the AMD part. The NVIDIA GeForce MX330 averages 8458, which is 0.3 percent higher than the AMD Radeon 880M. The AMD Radeon HD 8870M also averages 8458, matching the MX330 exactly at 0.3 percent above the Radeon 880M. The AMD Radeon R9 M375X trails at 8325, which is 1.3 percent behind the Radeon 880M.

These delta values are minimal, with the largest gap being just 1.3 percent. The AMD Radeon 880M sits in a performance band where four discrete mobile GPUs from previous generations land within a narrow range. The data indicates that the integrated Radeon 880M performs at a level comparable to older mid-range discrete parts, but the differences are small enough that individual workload characteristics would determine any practical advantage.

The Verdict

The benchmark data presents a lopsided comparison because the Intel Arc B770 has no recorded scores in the database. Its average benchmark score is listed as 0, and its nearest rivals list is empty. The percentile ranking for the Intel part is 50, which places it at the median of all GPUs, but this figure is not supported by any individual test results in the available data.

Without benchmark measurements for the Intel Arc B770, no direct performance verdict can be derived from recorded test scores. The AMD Radeon 880M has measurable results, and those results indicate a GPU that sits at the 43rd percentile among all GPUs, with an average score of 8436. The Intel Arc B770's median percentile of 50 suggests it is positioned differently in the database, but the absence of test data prevents any empirical comparison.

The specification sheets do allow for some general observations. The Intel Arc B770 is a dual-slot discrete card with a 225 W TDP, while the AMD Radeon 880M is an integrated graphics processor with a 15 W TDP. The power envelope difference is substantial. The Intel part requires a 550 W suggested power supply and uses one 6-pin plus one 8-pin power connector. The AMD part uses no power connectors and draws power through the system.

Users who need a drop-in integrated graphics solution for a portable device would select the AMD Radeon 880M based on its form factor alone. Users who require a discrete card with dedicated memory would select the Intel Arc B770. These conclusions follow from the physical and electrical specifications, not from benchmark performance, since the Intel part lacks recorded scores.

Where Each One Wins

The AMD Radeon 880M wins in scenarios where integrated graphics are required. Its IGP form factor means it occupies no expansion slot and uses no power connectors. The 15 W TDP fits within the power budget of a portable device. The boost clock of 2900 MHz exceeds the Intel part's boost clock, which may help in lightly threaded or clock-sensitive workloads that do not scale across the AMD part's 768 shading units.

The AMD Radeon 880M also wins in the specific benchmark tests where it has recorded data. The Passmark DirectX 9 score of 97 represents its strongest legacy API result. The Geekbench Vulkan score of 40006 and OpenCL score of 31285 show that the part handles compute-oriented API workloads better than its DirectX 10 and DirectX 12 results suggest. For users running applications that rely on Vulkan or OpenCL, the AMD part demonstrates measurable capability.

The Intel Arc B770 wins in every specification category that involves dedicated resources. The 16 GB GDDR6 memory with 512.0 GB/s bandwidth provides a dedicated memory pool, whereas the AMD part depends on system memory with bandwidth that varies by platform. The 256 bit memory bus is a fixed hardware resource, not a system-dependent value.

The Intel part wins on raw throughput metrics. The 19.66 TFLOPS FP32 figure, 39.32 TFLOPS FP16 figure, 307.2 GPixel/s pixel rate, and 614.4 GTexel/s texture rate all exceed the AMD part's corresponding values. The 4096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores provide a much larger execution resource pool.

The Intel Arc B770 wins in connectivity options. The one HDMI 2.1a port and three DisplayPort 2.1 ports give it fixed, known display outputs. The AMD Radeon 880M's outputs are listed as portable device dependent, meaning the available connections vary by the host device.

The PCIe interface favors the Intel part. The PCIe 4.0 x16 connection provides more host bandwidth than the AMD part's PCIe 4.0 x8 connection. For workloads that stream data between the CPU and GPU, the wider link reduces transfer bottlenecks.

The production status favors the AMD Radeon 880M, which is listed as active. The Intel Arc B770 has no recorded production status in the database, leaving its availability unconfirmed. The Intel part's release date of 2025-12-31 suggests it may not yet be available in the market.

The percentile ranking favors the Intel Arc B770 at 50, compared to the AMD Radeon 880M at 43. However, this ranking for the Intel part is not backed by individual test scores in the database, so it should be interpreted with caution. The AMD part's 43rd percentile is supported by ten recorded benchmark results.

The AMD Radeon 880M wins in power efficiency categories. The 15 W TDP allows deployment in systems without dedicated graphics power delivery. The Intel Arc B770 requires a 550 W suggested power supply and dual power connectors, limiting it to desktop systems with adequate power headroom.

For ray tracing workloads, the Intel Arc B770 has 32 ray tracing cores versus 12 on the AMD Radeon 880M. The database does not include ray tracing benchmark scores for either part, so the practical impact of this core count difference cannot be quantified from recorded data.

For compute workloads, the Passmark GPU compute score of 3719 for the AMD Radeon 880M provides a baseline. The Intel Arc B770 has no comparable score in the database, so its compute performance relative to the AMD part remains unmeasured.
