Architecture Differences

Both cards share the same foundational architecture: the BMG-G21 chip built on Xe2-HPG, fabricated on TSMC's 5 nm process. The transistor count is identical at 19,600 million, and the die size measures 272 mm². This means the compute capabilities scale from the same base design, with differences in enabled units and clock speeds rather than fundamental architectural changes.

The Arc B570 belongs to the Battlemage (Arc 5) generation, released on 2025-01-15. The Arc Pro B65 belongs to the Battlemage (Pro Series) generation, with a release date of 2026-03-31. The Pro variant is positioned for professional workloads, which is reflected in its larger memory pool and higher compute unit counts.

The shader configuration differs meaningfully. The Arc Pro B65 packs 2560 shading units, 160 texture mapping units, and 20 ray tracing cores. The Arc B570 has 2304 shading units, 144 TMUs, and 18 RT cores. This gives the Pro B65 an 11.1% advantage in shading units and TMUs, and a 10% advantage in RT cores. Both cards have 80 ROPs, so pixel output capabilities differ only through clock speeds.

The memory subsystem is where the two diverge most sharply. The Arc B570 uses 10 GB of GDDR6 over a 160-bit interface, yielding 380.0 GB/s of bandwidth. The Arc Pro B65 uses 32 GB of GDDR6 over a 256-bit interface, yielding 608.0 GB/s. That is a 60% bandwidth advantage and 220% more capacity for the Pro card.

Clock speeds favor the B570. Its base and boost clocks are both 2500 MHz, while the Pro B65 runs at 2400 MHz for both. The memory clock is identical at 2375 MHz, 19 Gbps effective. The B570's higher GPU clock partially offsets its lower unit count in raw throughput calculations.

The bus interface also differs: the B570 uses PCIe 4.0 x8, while the Pro B65 uses PCIe 5.0 x16. This gives the Pro card significantly more host bandwidth, which matters for professional workloads that move large datasets. Display outputs differ as well: the B570 has 1x HDMI 2.1a and 3x DisplayPort 2.1, while the Pro B65 has 4x DisplayPort 2.1 only.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the Intel Arc B570 and the Intel Arc Pro B65. The Arc B570 has recorded scores across multiple tests, while the Arc Pro B65 has no entries in the benchmark results section.

For the Arc B570, the recorded data shows a 3DMark Steel Nomad DX12 score of 2649. In Geekbench, it scores 83514 in OpenCL and 96844 in Vulkan. Passmark results include 65 in DirectX 10, 118 in DirectX 11, 72 in DirectX 12, 164 in DirectX 9, 661 in G2D, 14195 in G3D, and 7281 in GPU Compute. The average benchmark score is 20556, placing it in the 65th percentile of all GPUs.

The Arc Pro B65 has no benchmark scores, no average score, and no nearest rival data. Its percentile ranking of 50 is a placeholder rather than a measured result. This means any direct performance comparison must rely on the theoretical compute specifications rather than measured outcomes.

The nearest rivals for the Arc B570 provide context for its performance. The NVIDIA GeForce RTX 3070 Mobile scores 20534, which is 0.1% behind the B570. The Intel Arc A750 scores 20582, which is 0.1% ahead. The NVIDIA Quadro M4000M scores 20480, 0.4% behind. The AMD Radeon R9 M390X scores 20662, 0.5% ahead. These deltas are all within a fraction of a percent, indicating the B570 sits in a tightly contested performance band.

Where Each One Wins

The Arc B570 wins in clock speed and pixel throughput. Its 2500 MHz clock exceeds the Pro B65's 2400 MHz, and its pixel rate of 200.0 GPixel/s beats the Pro's 192.0 GPixel/s. For scenarios where higher clock speeds matter, such as lightly threaded rendering tasks or games that scale with frequency, the B570 holds an advantage.

The Arc Pro B65 wins in almost every other compute metric. It has more shading units, more TMUs, more RT cores, higher texture rate, and higher FP32 and FP16 throughput. The 11.1% shader advantage translates to 12.29 TFLOPS versus 11.52 TFLOPS in FP32, and 24.58 TFLOPS versus 23.04 TFLOPS in FP16. The Pro card also has a 60% bandwidth advantage and 220% more memory capacity.

For gaming workloads, the Arc B570 has the measured data to support its position. Its average benchmark score of 20556 and 65th percentile ranking come from actual test results. The Arc Pro B65 has no measured gaming performance, so its suitability for gaming is unverified.

For professional or compute-heavy workloads, the Arc Pro B65's specifications point to clear advantages. The 32 GB memory pool can hold much larger datasets than 10 GB. The 608.0 GB/s bandwidth moves data significantly faster. The PCIe 5.0 x16 interface provides substantially more host bandwidth than PCIe 4.0 x8. The higher FP32 and FP16 throughput benefits compute tasks.

The Arc B570 also wins on power efficiency per the recorded data. Its 150 W TDP is 25% lower than the Pro B65's 200 W, while delivering nearly comparable compute throughput. The B570 achieves 11.52 TFLOPS at 150 W, while the Pro achieves 12.29 TFLOPS at 200 W. The B570 delivers 76.8 GFLOPS per watt versus the Pro's 61.5 GFLOPS per watt.

The Verdict

The data shows two cards built on the same silicon but aimed at different use cases. The Intel Arc B570 is a gaming-oriented card with measured benchmark results, a 65th percentile ranking, and a launch MSRP of 219 USD. Its nearest rivals all sit within 0.5% of its average score, placing it in a competitive midrange segment.

The Intel Arc Pro B65 is a professional card with no measured benchmarks. Its specifications target workloads that need large memory capacity and high bandwidth. The 32 GB GDDR6 pool, 256-bit bus, 608.0 GB/s bandwidth, and PCIe 5.0 x16 interface make it suited for tasks like rendering large scenes, working with high-resolution textures, or processing big datasets in compute applications.

For gaming, the Arc B570 is the only choice with recorded performance data. Its 20556 average benchmark score and 65th percentile ranking come from actual test runs. The Pro B65 has no gaming benchmarks in the database, so its gaming performance cannot be assessed.

For professional workloads, the Arc Pro B65 has the specification advantage. More shading units, more TMUs, more RT cores, higher FP32 and FP16 throughput, and vastly more memory bandwidth and capacity point to better performance in compute-heavy tasks. The 200 W TDP and 550 W suggested PSU reflect the higher power draw required by these additional resources.

The choice depends on workload. Users building a gaming system should select the Arc B570, which has verified performance data and a lower power requirement. Users building a workstation for professional rendering or compute should select the Arc Pro B65, which has the specifications to handle larger and more demanding workloads, despite lacking measured benchmark results.
