AMD Radeon PRO W7900 vs Intel Arc Pro B70 Comparison

AMD Radeon PRO W7900 vs Intel Arc Pro B70

Head-to-Head Benchmarks

The database currently holds no direct head-to-head benchmark results between the AMD Radeon PRO W7900 and the Intel Arc Pro B70. The Arc Pro B70 has no recorded benchmark scores in our database, with an average benchmark score of 0 and a percentile rank of 50 among all GPUs. The Radeon PRO W7900, by contrast, has two recorded benchmark entries: a Geekbench OpenCL score of 84,379 and a Geekbench Vulkan score of 137,070, producing an average benchmark score of 110,725 and a percentile rank of 94.

Because the Arc Pro B70 lacks any recorded scores, a direct numerical comparison between the two cards is not possible from the available data. The Radeon PRO W7900’s nearest rivals in the database provide context for its performance tier. It sits 1% above the AMD Radeon Pro Vega II (average score 109,617), 3.2% above the AMD Radeon Pro W6600X (107,342), 2.8% below the NVIDIA RTX A5500 Mobile (113,944), and 3.2% below the NVIDIA Tesla V100 SXM2 16 GB (114,395). This places the W7900 in a competitive band around 110,000 to 114,000 average benchmark points, with a slight edge over older AMD workstation cards and a small deficit against those two NVIDIA offerings.

The Arc Pro B70’s lack of benchmark data means its real-world performance cannot be validated against the W7900 or any other GPU in the database. Its 50th percentile ranking is a placeholder, not a measured result. Until benchmark entries are populated for the Arc Pro B70, any performance comparison relies entirely on architectural and specification differences rather than empirical scores.

Architecture Differences

The two cards use different GPU architectures from different manufacturers. The AMD Radeon PRO W7900 uses the Navi 31 chip, built on RDNA 3.0 architecture, with the codename Plum Bonito, part of the Radeon Pro Navi (Navi III Series) generation. The Intel Arc Pro B70 uses the BMG-G31 chip, built on Xe2-HPG architecture, part of the Battlemage (Pro Series) generation.

Both are fabricated on a 5 nm process at TSMC. The W7900’s Navi 31 die measures 529 mm² and contains 57,700 million transistors, resulting in a transistor density of 109.1M per mm². The Arc Pro B70’s BMG-G31 die is smaller at 368 mm², with transistor count listed as unknown and no density figure recorded.

Core configurations differ significantly. The Radeon PRO W7900 has 6,144 shading units, 384 texture mapping units, 192 render output units, and 96 ray tracing cores. The Intel Arc Pro B70 has 4,096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. Neither card has tensor cores listed.

Compute throughput tells a clear story. The W7900 delivers 61.32 TFLOPS FP32 and 61.32 TFLOPS FP16 with a 1:1 ratio. The Arc Pro B70 delivers 22.94 TFLOPS FP32 and 45.88 TFLOPS FP16 with a 2:1 ratio. The W7900 has roughly 2.7 times the FP32 throughput and 1.3 times the FP16 throughput of the Arc Pro B70.

Clock speeds favor the Intel card. The Arc Pro B70 has a base clock of 2280 MHz and a boost clock of 2800 MHz. The Radeon PRO W7900 has a base clock of 1760 MHz and a boost clock of 2495 MHz. The Arc Pro B70 runs about 30% higher at base and 12% higher at boost, but its lower core count and narrower memory bus prevent it from matching the W7900’s raw compute output.

Pixel and texture rates follow the core counts. The W7900 achieves 479.0 GPixel/s pixel rate and 958.1 GTexel/s texture rate. The Arc Pro B70 achieves 358.4 GPixel/s and 716.8 GTexel/s. The W7900 leads by about 34% in pixel rate and 34% in texture rate.

Where Each One Wins

Based on the recorded data, the Radeon PRO W7900 wins decisively in raw compute, memory capacity, and memory bandwidth. Its 61.32 TFLOPS FP32 output is 2.7 times the Arc Pro B70’s 22.94 TFLOPS. Its 48 GB GDDR6 memory doubles the Arc Pro B70’s 32 GB, and its 864.0 GB/s bandwidth exceeds the Arc Pro B70’s 608.0 GB/s by 42%. The W7900 also has triple the ray tracing cores (96 vs 32), which suggests stronger ray tracing workloads, though no benchmark data confirms this.

The Intel Arc Pro B70 wins on power efficiency and physical footprint. Its 230 W TDP is 65 W lower than the W7900’s 295 W. It uses a single 8-pin power connector versus the W7900’s dual 8-pin connectors, and its suggested PSU is 550 W versus 600 W. The Arc Pro B70 is a dual-slot card measuring 267 mm in length, 110 mm in height, and 39 mm in width. The W7900 is a triple-slot card measuring 280 mm in length, 110 mm in height, and 51 mm in width. The Arc Pro B70 is 13 mm shorter and 12 mm thinner, making it easier to fit in compact workstation cases.

The Arc Pro B70 also has a higher boost clock at 2800 MHz versus 2495 MHz, and a faster memory clock at 2375 MHz (19 Gbps effective) versus 2250 MHz (18 Gbps effective). These higher clocks indicate better frequency headroom, but they do not compensate for the W7900’s larger core count and wider 384-bit memory bus.

The launch MSRP for the Radeon PRO W7900 is 3,999 USD. The launch MSRP for the Intel Arc Pro B70 is 949 USD.

The Verdict

The AMD Radeon PRO W7900 is the clear performance leader based on every recorded compute metric. Its FP32 output of 61.32 TFLOPS dwarfs the Arc Pro B70’s 22.94 TFLOPS. Its 48 GB memory capacity and 864.0 GB/s bandwidth suit large datasets and high-resolution rendering workloads. The W7900’s 96 ray tracing cores triple the Arc Pro B70’s 32, and its pixel rate of 479.0 GPixel/s and texture rate of 958.1 GTexel/s both exceed the Arc Pro B70 by roughly one-third. The database confirms the W7900 performs at the 94th percentile among all GPUs, with an average benchmark score of 110,725.

The Intel Arc Pro B70 has no measured benchmark data, so its actual performance is unverified. Its architecture does offer advantages in power draw and physical size. The 230 W TDP, single 8-pin connector, and dual-slot profile make it easier to integrate into space-constrained builds. Its PCIe 5.0 x16 interface provides double the bus bandwidth of the W7900’s PCIe 4.0 x16, which could benefit data transfer in supported systems. The higher boost clock of 2800 MHz and memory clock of 2375 MHz indicate the design has frequency headroom, but the lower core counts and 256-bit memory bus limit its ceiling.

Users who need maximum compute throughput, the largest memory pool, and proven benchmark scores should select the Radeon PRO W7900. Users who prioritize lower power consumption, a smaller card footprint, and a much lower launch MSRP of 949 USD versus 3,999 USD should consider the Intel Arc Pro B70, provided they accept that its performance is not yet verified in the database. The release date difference matters as well: the W7900 launched in May 2023, while the Arc Pro B70 launched in March 2026, making the Intel card a newer design with more recent features such as PCIe 5.0. The choice hinges on whether verified performance and raw specifications outweigh the Arc Pro B70’s efficiency, size, and price advantages.
