The Verdict

The data indicates these two cards serve different primary purposes. The Intel Arc B770 is built for high-throughput rasterization and pixel pushing. Its 512.0 GB/s memory bandwidth, 256 TMUs, and 128 ROPs give it a commanding lead in texture-heavy and resolution-bound rendering tasks. The NVIDIA RTX PRO 2000 Blackwell, by contrast, is a low-power workstation card with tensor core support and a much smaller physical footprint.

For workloads that depend on raw fill rates and memory bandwidth, such as high-resolution gaming or compute that benefits from large data movement, the Intel Arc B770 is the stronger choice. Its 19.66 TFLOPS FP32 and 39.32 TFLOPS FP16 (2:1) performance exceed the NVIDIA card’s 17.03 TFLOPS in both precision modes. The NVIDIA card uses a 1:1 FP16 ratio, meaning it does not accelerate half-precision tasks beyond FP32 rates.

For AI inference, machine learning, or applications that leverage tensor operations, the NVIDIA RTX PRO 2000 Blackwell is the only option with dedicated hardware. The Intel card has no tensor cores, so any AI workload would rely solely on standard shader compute. The NVIDIA card also holds the higher percentile ranking at 70 versus 50 for Intel, indicating better overall benchmark standing across all GPUs in the database.

The NVIDIA card’s 70 W TDP and slot-powered design make it suitable for compact or power-constrained systems, while the Intel card requires a 550 W power supply. Users needing a dual-slot card with no external power connectors and a 167 mm length will find the NVIDIA option easier to integrate into small form factor builds.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two cards, but the NVIDIA RTX PRO 2000 Blackwell has recorded benchmark scores across multiple tests. The Intel Arc B770 has no benchmark entries, so the comparison relies on specification-based analysis.

The NVIDIA card scores 2374.5 in 3DMark Steel Nomad DX12, 106087 in Geekbench OpenCL, and 113865 in Geekbench Vulkan. Its Passmark G3D score is 20049, with a GPU compute score of 8396. The average benchmark score for the NVIDIA card is 25269, placing it in the 70th percentile of all GPUs.

The nearest rivals to the NVIDIA RTX PRO 2000 Blackwell provide context for its performance. The AMD Radeon RX 6700M has an average score of 25633, which is 1.4% higher. The AMD Radeon Pro W5700 scores 25726, 1.8% higher. The NVIDIA GeForce RTX 3080 Ti Mobile also scores 25740, 1.8% higher. The NVIDIA RTX A5000 Mobile scores 24763, which is 2% lower than the RTX PRO 2000 Blackwell.

These deltas show the NVIDIA card sits within a tight performance band, roughly 2% below its closest competitors and 2% above the RTX A5000 Mobile. The Intel card has no comparable benchmark data, so its relative standing cannot be quantified from the database.

Specification Differences

The most significant differences lie in memory architecture and power delivery. The Intel Arc B770 uses 16 GB of GDDR6 on a 256-bit bus, yielding 512.0 GB/s bandwidth. The NVIDIA RTX PRO 2000 Blackwell uses 16 GB of GDDR7 on a 128-bit bus, yielding 288.0 GB/s. The Intel card has 4096 shading units, 256 TMUs, and 128 ROPs, while the NVIDIA card has 4352 shading units, 136 TMUs, and 48 ROPs.

Clock speeds differ substantially. The Intel card runs at a 2100 MHz base and 2400 MHz boost, with memory at 2000 MHz or 16 Gbps effective. The NVIDIA card runs at a 982 MHz base and 1957 MHz boost, with memory at 1125 MHz or 18 Gbps effective. Despite the lower memory clock, the NVIDIA card’s GDDR7 memory achieves a higher effective data rate per pin.

Power consumption separates these cards clearly. The Intel Arc B770 has a 225 W TDP, requires a 550 W power supply, and uses one 6-pin plus one 8-pin connector. The NVIDIA RTX PRO 2000 Blackwell has a 70 W TDP, requires a 250 W power supply, and needs no external power connectors. The NVIDIA card is also physically smaller at 167 mm by 69 mm by 20 mm, while the Intel card has no listed dimensions.

The bus interface differs: the Intel card uses PCIe 4.0 x16, while the NVIDIA card uses PCIe 5.0 x8. Display outputs also vary, with the Intel card offering one HDMI 2.1a and three DisplayPort 2.1, while the NVIDIA card offers four mini-DisplayPort 2.1b connections.

The NVIDIA card has an active production status and a release date of 2025-08-10. The Intel card has a release date of 2025-12-31 and no listed production status. The NVIDIA card’s chip, GB206, contains 21,900 million transistors on a 181 mm² die with a density of 121.0 million per square millimeter. The Intel card’s chip, BMG-G31, has a 368 mm² die with an unknown transistor count.

Architecture Differences

The Intel Arc B770 uses the Xe2-HPG architecture from the Battlemage generation, built on a 5 nm process at TSMC. The NVIDIA RTX PRO 2000 Blackwell uses the Blackwell 2.0 architecture from the Blackwell PRO W generation, also built on a 5 nm process at TSMC. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Ray tracing hardware differs in count. The Intel card has 32 RT cores, while the NVIDIA card has 34 RT cores. The NVIDIA card also includes 136 tensor cores, which are absent from the Intel card. This tensor core presence enables AI acceleration, a feature the Intel architecture does not provide.

The FP16 compute capability highlights an architectural divergence. The Intel card achieves 39.32 TFLOPS FP16 with a 2:1 ratio relative to FP32, meaning it doubles throughput in half-precision. The NVIDIA card achieves 17.03 TFLOPS FP16 with a 1:1 ratio, meaning half-precision runs at the same rate as FP32 without specialized acceleration.

The NVIDIA card’s predecessor is Workstation Ada, while the Intel card’s predecessor is Alchemist. The Intel card belongs to the Arc 7 series with a Battlemage generation label, while the NVIDIA card belongs to the Blackwell PRO W series with an x000 generation label.

The NVIDIA card has a transistor density of 121.0 million per square millimeter, which reflects a dense design on a smaller die. The Intel card’s larger die size of 368 mm² suggests a different balance between compute units and memory interface, but without transistor count data, the density cannot be calculated.

The memory type also reflects architectural differences: GDDR6 for Intel versus GDDR7 for NVIDIA. The newer GDDR7 standard allows a higher effective clock per pin, but the Intel card compensates with a wider 256-bit bus.

Where Each One Wins

The Intel Arc B770 wins in scenarios that demand high memory bandwidth and high fill rates. Its 512.0 GB/s bandwidth supports large textures and high-resolution rendering, while its 307.2 GPixel/s pixel rate and 614.4 GTexel/s texture rate outpace the NVIDIA card’s 93.94 GPixel/s and 266.2 GTexel/s. Workloads that saturate the ROPs or TMUs, such as traditional rasterized gaming at high resolutions, favor the Intel card.

The Intel card also wins in FP32 and FP16 compute throughput. Its 19.66 TFLOPS FP32 exceeds the NVIDIA card’s 17.03 TFLOPS, and its 39.32 TFLOPS FP16 provides a clear advantage for half-precision workloads. The 256-bit memory bus and 128 ROPs give it a structural edge in bandwidth-bound tasks.

The NVIDIA RTX PRO 2000 Blackwell wins in power efficiency and form factor. A 70 W TDP with no external power connectors means it fits into systems with a 250 W power supply, while the Intel card needs 550 W. The 167 mm length and 69 mm height make it suitable for compact chassis, and the PCIe 5.0 x8 interface offers higher bandwidth per lane.

The NVIDIA card wins in AI and tensor-based workloads due to its 136 tensor cores. Applications that use CUDA or tensor operations, such as machine learning inference or neural network training, benefit from dedicated hardware that the Intel card does not offer. The NVIDIA card also wins in overall benchmark percentile, sitting at 70 versus 50 for Intel.

The NVIDIA card’s benchmark scores provide a concrete performance baseline. Its 2374.5 score in 3DMark Steel Nomad DX12 and 113865 in Geekbench Vulkan indicate solid DirectX and Vulkan performance. Its Passmark G3D score of 20049 and compute score of 8396 confirm balanced general-purpose performance. The Intel card has no recorded benchmark scores, so its practical performance cannot be verified from the database.

For users prioritizing low power consumption, compact size, and AI acceleration, the NVIDIA RTX PRO 2000 Blackwell is the clear choice. For users prioritizing raw rendering throughput, memory bandwidth, and higher FP32 and FP16 compute, the Intel Arc B770 delivers more on paper. The data shows no single winner across all metrics, so the selection depends on the specific workload.
