AMD Radeon RX 7900M vs Intel Arc Pro B65 Comparison

The Verdict

The database contains no head-to-head benchmark comparisons between the AMD Radeon RX 7900M and the Intel Arc Pro B65, and the Intel part has no recorded benchmark scores of its own. The AMD card, however, has a complete measurement set. Its average benchmark score of 97487 places it in the 94th percentile of all GPUs in the database. That percentile ranking means the RX 7900M sits above the overwhelming majority of recorded graphics processors. The Intel Arc Pro B65 holds a 50th percentile ranking with an average benchmark score of zero, indicating no recorded performance data exists for it in the database. For any application where measured performance matters, the AMD Radeon RX 7900M is the only option with demonstrated results. The Intel card offers double the memory capacity and a newer bus interface, but without benchmark data, its actual performance cannot be quantified. Users who need verified performance should select the AMD part based on the recorded data. Users who need maximum memory capacity and a dual-slot form factor with a modern display output set have only the Intel option, but they must accept that its performance is unmeasured in the database.

Architecture Differences

The two processors come from different architectural lineages. The AMD Radeon RX 7900M uses the Navi 31 chip with RDNA 3.0 architecture, codenamed Plum Bonito, and belongs to the Navi Mobile generation within the RX 7000 series. The Intel Arc Pro B65 uses the BMG-G21 chip with Xe2-HPG architecture and belongs to the Battlemage Pro Series generation. Both chips are fabricated on a 5 nm process at TSMC, but the dies differ substantially in scale. The AMD chip contains 57,700 million transistors on a 529 mm² die, giving a transistor density of 109.1 million per square millimeter. The Intel chip contains 19,600 million transistors on a 272 mm² die, with a transistor density of 72.1 million per square millimeter. The AMD chip has nearly three times the transistor count and almost double the die area.

The compute resources diverge sharply. The Radeon RX 7900M provides 4608 shading units, 288 texture mapping units, 192 render output units, and 72 ray tracing cores. The Arc Pro B65 provides 2560 shading units, 160 texture mapping units, 80 render output units, and 20 ray tracing cores. The AMD card has 80% more shading units, 80% more texture units, 140% more render output units, and 260% more ray tracing cores. Neither card has tensor cores listed in the database.

Clock behavior differs. The AMD card runs a base clock of 1825 MHz and a boost clock of 2090 MHz. The Intel card runs a fixed 2400 MHz for both base and boost. The memory clock also differs: AMD uses 2250 MHz with 18 Gbps effective, while Intel uses 2375 MHz with 19 Gbps effective.

The API support is identical on paper: both support DirectX 12 Ultimate with feature level 12_2, OpenGL 4.6, and Vulkan 1.4. The production status for both is Active. The AMD card released on 2023-10-18, while the Intel card released on 2026-03-31, a gap of roughly two and a half years in release timing.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries comparing the AMD Radeon RX 7900M and the Intel Arc Pro B65. The head-to-head benchmark array is empty, and the win counts are zero for both cards. However, the AMD card's individual benchmark scores can be examined on their own terms.

The AMD Radeon RX 7900M scores 4201 in 3DMark Steel Nomad DX12. That is a synthetic DirectX 12 test measuring graphics workload performance. The Geekbench OpenCL score is 129499, which reflects general-purpose compute performance across a range of workloads. The Geekbench Vulkan score is 158760, which measures cross-platform graphics and compute performance through the Vulkan API. The Vulkan score exceeds the OpenCL score by roughly 22.6%.

The average benchmark score for the AMD card is 97487, which is the mean of its recorded results. Its nearest rivals in the database provide context for this score. The AMD Radeon Pro VII has an average score of 97131, which is 0.4% lower than the RX 7900M, meaning the RX 7900M is essentially tied with that card. The NVIDIA Quadro RTX 6000 has an average score of 101872, which is 4.3% higher than the RX 7900M, so the RX 7900M trails that card. The AMD Radeon Instinct MI60 has an average score of 92466, which is 5.4% lower, meaning the RX 7900M leads that card. The NVIDIA RTX A4500 has an average score of 91671, which is 6.3% lower, so the RX 7900M leads that card by a wider margin.

The percentile ranking of 94 for the RX 7900M indicates that it outperforms 94% of all GPUs in the database. The Intel Arc Pro B65, with no benchmarks and a 50th percentile ranking, has no comparable measurements. The data shows that the AMD card, while not the top performer in its nearest rival group, holds its own against professional workstation cards and clearly outperforms two of its four nearest rivals.

Where Each One Wins

Looking strictly at the recorded data, the AMD Radeon RX 7900M wins in every measured performance category. Its FP32 throughput of 38.52 TFLOPS is more than triple the Intel Arc Pro B65's 12.29 TFLOPS. Its pixel rate of 401.3 GPixel/s is more than double the Intel card's 192.0 GPixel/s. Its texture rate of 601.9 GTexel/s exceeds the Intel card's 384.0 GTexel/s by a factor of roughly 1.6. Its shading unit count of 4608 versus 2560 gives it a 1.8x advantage in parallel compute lanes. Its ray tracing core count of 72 versus 20 gives it a 3.6x advantage in hardware ray tracing resources.

The Intel Arc Pro B65 wins in memory capacity, memory bandwidth, and bus interface. The Intel card has 32 GB of GDDR6 versus 16 GB for AMD, which is double the capacity. The Intel card's memory bandwidth of 608.0 GB/s exceeds the AMD card's 576.0 GB/s by about 5.6%. The Intel card uses PCIe 5.0 x16, which is a newer generation than the AMD card's PCIe 4.0 x16. The Intel card also has a standardized display output configuration of 4x DisplayPort 2.1, while the AMD card's display outputs are portable device dependent.

The Intel card also has a higher base clock of 2400 MHz versus 1825 MHz for AMD, and a higher memory clock of 2375 MHz versus 2250 MHz. However, the AMD card's boost clock of 2090 MHz is lower than the Intel card's fixed 2400 MHz boost.

The AMD card wins in power efficiency on paper: 180 W TDP versus 200 W for Intel, while delivering more than three times the FP32 throughput. The AMD card also has a higher transistor density of 109.1M per mm² versus 72.1M per mm², indicating a more compact integration of logic.

For use cases implied by the data: the AMD card suits workloads requiring maximum compute throughput, high pixel and texture fill rates, and substantial ray tracing resources. Its 94th percentile ranking confirms strong overall performance. The Intel card suits workloads requiring very large memory capacity for large datasets or models, and it provides a dual-slot form factor with a standard 8-pin power connector and a suggested 550 W power supply, which may fit certain system configurations. The Intel card also offers the newer PCIe 5.0 interface and DisplayPort 2.1 outputs, which matter for display connectivity and bandwidth. However, without any benchmark scores for the Intel card, its actual performance in compute or graphics workloads remains unknown in the database. The recorded data strongly favors the AMD card for any performance-sensitive task.
