AMD Radeon 890M vs Intel Arc Pro B390 Comparison

AMD Radeon 890M vs Intel Arc Pro B390

Head-to-Head Benchmarks

The recorded data does not contain any direct head-to-head benchmark comparisons between the AMD Radeon 890M and the Intel Arc Pro B390. The database shows no shared test results for these two integrated graphics processors. The AMD Radeon 890M has a full set of ten benchmark scores across multiple suites, while the Intel Arc Pro B390 has no benchmark entries in the database at all. This means the Intel part currently has no measured performance data, no average score, and no percentile ranking based on actual tests. The AMD part, by contrast, has an average benchmark score of 9210 and sits at the 45th percentile among all GPUs in the database.

For the AMD Radeon 890M alone, the individual benchmark results show a wide spread of performance depending on the workload. In Geekbench Vulkan, it scores 40808, and in Geekbench OpenCL it scores 37254. PassMark G3D gives it 8076, while PassMark G2D gives it 979. Compute-oriented testing via PassMark GPU Compute produces a score of 4157. DirectX-specific PassMark tests show 97 in DirectX 9, 73 in DirectX 11, 37 in DirectX 12, and 33 in DirectX 10. The 3DMark Steel Nomad DX12 test yields a score of 590. The nearest rivals for the 890M in the database are the AMD Radeon Vega 8 with an average score of 9221, the NVIDIA GeForce GTX 960 at 9273, the NVIDIA GeForce GTX 465 at 9294, and the NVIDIA GeForce GTX 850M at 9302. The delta percentages for the 890M against these rivals are -0.1%, -0.7%, -0.9%, and -1% respectively, indicating the 890M trails each of them by roughly one percent or less in average score.

Because the Intel Arc Pro B390 has no benchmark scores, no nearest rivals, and an average benchmark score of zero, the data cannot establish any head-to-head winner. The Intel part does have a percentile ranking of 50 against all GPUs, which is higher than the AMD part's 45th percentile, but this percentile is not derived from any recorded test scores. The absence of measured data for the Intel Arc Pro B390 means any performance comparison between these two iGPUs is not possible from the database at this time.

Architecture Differences

The AMD Radeon 890M uses the Strix Point chip built on RDNA 3.5 architecture, manufactured on a 4 nm process at TSMC. The Intel Arc Pro B390 uses the Panther Lake chip built on Xe3-LPG architecture, manufactured on a 3 nm process at Intel. The process node difference is meaningful: AMD uses a 4 nm node while Intel uses a 3 nm node. The AMD chip contains 34,000 million transistors on a die size of 233 mm², giving a transistor density of 145.9 million transistors per square millimeter. The Intel chip's transistor count and die size are listed as unknown, and its transistor density is not recorded.

The AMD Radeon 890M belongs to the Navi III IGP generation for Strix Point Mobile, while the Intel Arc Pro B390 belongs to the Arc Graphics-WM generation for Panther Lake. The AMD part's predecessor is the Navi II IGP, and the Intel part's predecessor is the HD Graphics-WM. Both are active production parts. The AMD release date is 2024-07-14, while the Intel release date is 2026-01-26, making the Intel part a later product by roughly a year and a half.

Shader and fixed-function hardware differ significantly. The Intel Arc Pro B390 has 1536 shading units compared to 1024 on the AMD Radeon 890M, a 50% advantage in raw shader count. However, the AMD part has 64 texture mapping units versus 48 on Intel, and 32 render output units versus 24 on Intel. Ray tracing cores also differ: AMD has 16, Intel has 12. Neither part lists tensor cores. The Intel part has higher theoretical FP32 throughput at 7.680 TFLOPS versus 5.939 TFLOPS for AMD, a 29% advantage. In FP16, the Intel part reaches 15.36 TFLOPS with a 2:1 ratio, while AMD achieves 5.939 TFLOPS with a 1:1 ratio. Pixel rate favors AMD at 92.80 GPixel/s versus 60.00 GPixel/s for Intel, and texture rate also favors AMD at 185.6 GTexel/s versus 120.0 GTexel/s.

Clock behavior differs as well. The AMD part has a base clock of 400 MHz and a boost clock of 2900 MHz. The Intel part has a base clock of 300 MHz and a boost clock of 2500 MHz. Both use system shared memory with system-dependent bandwidth. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The power envelope is very different: the AMD Radeon 890M is rated at 15 W, while the Intel Arc Pro B390 is rated at 80 W. Both are IGP slot-width parts with no power connectors. The AMD part uses a PCIe 4.0 x8 bus interface, while the Intel part's bus interface is listed simply as IGP. Display outputs for both are portable device dependent.

The Intel part has 1536 shading units, 48 TMUs, 24 ROPs, and 12 RT cores. Neither has tensor cores. Pixel rate is 92.80 GPixel/s for AMD and 60.00 GPixel/s for Intel. Texture rate is 185.6 GTexel/s for AMD and 120.0 GTexel/s for Intel. FP32 is 5.939 TFLOPS for AMD and 7.680 TFLOPS for Intel. FP16 is 5.939 TFLOPS with a 1:1 ratio for AMD and 15.36 TFLOPS with a 2:1 ratio for Intel.

The AMD predecessor is Navi II IGP, and the Intel predecessor is HD Graphics-WM. Neither part has a successor listed, and neither has a launch MSRP.

The Verdict

The data supports only a limited verdict because the Intel Arc Pro B390 has no benchmark scores in the database. The AMD Radeon 890M has a complete set of ten recorded benchmark results, an average score of 9210, and a 45th percentile ranking. The Intel Arc Pro B390 has an average score of zero and a 50th percentile ranking that is not backed by any measured tests. Direct comparison of performance is therefore impossible from the recorded data. The AMD part is proven in terms of measured output, while the Intel part is unmeasured.

For users who prioritize measured performance data and a full benchmark profile, the AMD Radeon 890M is the only part with recorded results. Its average score of 9210 places it within 1% of four nearest rivals, all of which are discrete or older integrated GPUs. For users who prioritize theoretical specifications, the Intel Arc Pro B390 offers a higher shader count, higher FP32 throughput, and higher FP16 throughput, but these advantages come with an 80 W TDP versus 15 W for the AMD part. The AMD part also has higher pixel rate, higher texture rate, more TMUs, more ROPs, more RT cores, and a higher boost clock. The Intel part uses a smaller 3 nm process and has a later release date. Without benchmark data for the Intel part, the database cannot confirm whether its theoretical advantages translate into actual performance wins.

Where Each One Wins

The AMD Radeon 890M wins on measured benchmark availability, with ten recorded scores across 3DMark, Geekbench OpenCL, Geekbench Vulkan, and multiple PassMark tests. It also wins on texture rate at 185.6 GTexel/s versus 120.0 GTexel/s, pixel rate at 92.80 GPixel/s versus 60.00 GPixel/s, TMU count at 64 versus 48, ROP count at 32 versus 24, RT core count at 16 versus 12, and boost clock at 2900 MHz versus 2500 MHz. Its TDP of 15 W is substantially lower than the Intel part's 80 W, which is an advantage in power-constrained systems. Its bus interface is PCIe 4.0 x8, while the Intel part is listed only as IGP.

The Intel Arc Pro B390 wins on shading units at 1536 versus 1024, FP32 throughput at 7.680 TFLOPS versus 5.939 TFLOPS, and FP16 throughput at 15.36 TFLOPS versus 5.939 TFLOPS. It also uses a smaller 3 nm process node compared to AMD's 4 nm node, and it has a later release date of 2026-01-26 versus 2024-07-14. Its percentile ranking of 50 is higher than the AMD part's 45, though this ranking is not tied to any recorded benchmark scores. The Intel part has no benchmark results, no average score, and no nearest rivals in the database, so its wins are entirely based on specification sheets rather than measured data.
