Intel Arc B770 vs NVIDIA RTX PRO 5000 Blackwell Comparison

Head-to-Head Benchmarks

Direct head-to-head benchmark comparisons between the Intel Arc B770 and the NVIDIA RTX PRO 5000 Blackwell are not available in the recorded database. This absence of matching test data means a traditional side-by-side scoring table cannot be constructed. However, the database does contain standalone benchmark results for the RTX PRO 5000 Blackwell, and these measurements provide a reference point for its performance tier.

The RTX PRO 5000 Blackwell records a 3DMark Steel Nomad DX12 score of 9579.5. In Geekbench compute tests, it scores 254116 in OpenCL and 282631 in Vulkan. Its average benchmark score across all recorded tests is 182109. This places the card at the 98th percentile among all GPUs in the database, indicating that it outperforms the vast majority of recorded graphics hardware.

The RTX PRO 5000 Blackwell's nearest rivals in the database, based on average benchmark scores, include the NVIDIA A100 SXM4 80 GB with an average score of 183725, which is 0.9% higher than the RTX PRO 5000 Blackwell. The NVIDIA RTX 5000 Ada Generation posts an average of 184664, 1.4% higher. The NVIDIA GeForce RTX 4090 D achieves 178050, which is 2.3% lower. The NVIDIA A100 SXM4 40 GB reaches 187147, 2.7% higher. These deltas show the RTX PRO 5000 Blackwell sits within a tight cluster of high-end accelerators, slightly behind the A100 variants and the RTX 5000 Ada, while modestly ahead of the RTX 4090 D.

For the Intel Arc B770, the database records no benchmark scores and no nearest rival entries. Its percentile rank is 50, which places it at the median of all GPUs in the database. The absence of measured performance data means quantitative comparisons against the RTX PRO 5000 Blackwell cannot be derived from recorded results. The Arc B770's average benchmark score is listed as 0, which reflects the lack of recorded tests rather than a performance indication.

Without head-to-head results, the performance gap between these two cards must be inferred from their architectural specifications and the RTX PRO 5000 Blackwell's measured standing among other GPUs. The RTX PRO 5000 Blackwell's 98th percentile rank and its proximity to A100-class accelerators suggest it operates in a performance tier far above the median position occupied by the Arc B770.

Architecture Differences

The Intel Arc B770 uses the BMG-G31 chip built on the Xe2-HPG architecture, part of the Battlemage generation within the Arc 7 family. The NVIDIA RTX PRO 5000 Blackwell uses the GB202 chip with the Blackwell 2.0 architecture, belonging to the Blackwell PRO W generation. Both are manufactured on a 5 nm process at TSMC, so the underlying fabrication node is identical.

Die size differs substantially. The Arc B770 has a die size of 368 mm², while the RTX PRO 5000 Blackwell measures 750 mm². The NVIDIA chip packs 92,200 million transistors, resulting in a transistor density of 122.9M per mm². The Intel card's transistor count is listed as unknown, so no density figure can be computed from the database.

Memory configuration diverges sharply. The Arc B770 carries 16 GB of GDDR6 on a 256-bit bus, delivering 512.0 GB/s of bandwidth. The RTX PRO 5000 Blackwell uses 48 GB of GDDR7 on a 384-bit bus, achieving 1.34 TB/s. The NVIDIA card offers triple the capacity and more than double the bandwidth. Memory clock rates also differ: the Arc B770 runs at 2000 MHz with 16 Gbps effective, while the RTX PRO 5000 Blackwell operates at 1750 MHz with 28 Gbps effective.

Shader resources show a large gap. The Arc B770 has 4096 shading units, 256 TMUs, and 128 ROPs. The RTX PRO 5000 Blackwell has 14080 shading units, 440 TMUs, and 160 ROPs. The NVIDIA card provides more than three times the shading units, nearly double the texture mapping units, and 25% more raster operation units. Ray tracing hardware follows the same pattern: the Arc B770 has 32 RT cores, while the RTX PRO 5000 Blackwell has 110. Tensor cores exist only on the NVIDIA card, with 440 units; the Intel card lists none.

Compute throughput reflects these resource differences. The Arc B770 delivers 19.66 TFLOPS FP32 and 39.32 TFLOPS FP16 with a 2:1 ratio. The RTX PRO 5000 Blackwell delivers 66.94 TFLOPS FP32 and 66.94 TFLOPS FP16 with a 1:1 ratio. The NVIDIA card offers 3.4 times the FP32 throughput and 1.7 times the FP16 throughput. Pixel and texture rates follow: the Arc B770 produces 307.2 GPixel/s and 614.4 GTexel/s, while the RTX PRO 5000 Blackwell produces 380.3 GPixel/s and 1,045.9 GTexel/s.

Power and connectivity differ as well. The Arc B770 has a TDP of 225 W with a suggested PSU of 550 W and uses one 6-pin plus one 8-pin power connector. The RTX PRO 5000 Blackwell has a TDP of 300 W with a suggested PSU of 700 W and uses a single 16-pin connector. Both are dual-slot cards. The Arc B770 uses PCIe 4.0 x16, while the RTX PRO 5000 Blackwell uses PCIe 5.0 x16. Display outputs also differ: the Intel card provides 1x HDMI 2.1a and 3x DisplayPort 2.1, while the NVIDIA card provides 4x DisplayPort 2.1b.

API support is identical: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX PRO 5000 Blackwell has a production status of Active, while the Arc B770 lists none. Release dates differ: the Arc B770 is dated 2025-12-31, and the RTX PRO 5000 Blackwell is dated 2025-03-17. The Intel card's predecessor is Alchemist, while the NVIDIA card's predecessor is Workstation Ada.

Where Each One Wins

The RTX PRO 5000 Blackwell wins across every measurable compute and memory specification. Its 66.94 TFLOPS FP32 throughput is 3.4 times that of the Arc B770. Its 1.34 TB/s memory bandwidth is 2.6 times higher. Its 48 GB memory capacity is three times larger. The NVIDIA card also leads in shading units, texture units, raster operations, ray tracing cores, and pixel/texture fill rates. Its 98th percentile rank among all GPUs confirms that its performance class sits near the top of the database, with measured benchmark scores placing it within a few percentage points of A100-class accelerators.

The RTX PRO 5000 Blackwell's 440 tensor cores provide dedicated AI compute hardware that the Arc B770 lacks entirely. Its PCIe 5.0 interface doubles the bus bandwidth of the Arc B770's PCIe 4.0 connection. The NVIDIA card also supports a higher memory clock in effective terms, 28 Gbps versus 16 Gbps, and uses a wider 384-bit bus. Its 4x DisplayPort 2.1b outputs exceed the Arc B770's combination of one HDMI 2.1a and three DisplayPort 2.1 ports. The RTX PRO 5000 Blackwell also has a longer recorded production history, with a March 2025 release date and Active status, while the Arc B770's release date is listed at the end of 2025 with no production status.

The Intel Arc B770 has advantages in power efficiency. Its TDP of 225 W is 75 W lower than the RTX PRO 5000 Blackwell's 300 W. The suggested PSU requirement is also lower at 550 W versus 700 W. The Arc B770 uses two conventional power connectors, a 6-pin and an 8-pin, rather than the single 16-pin connector on the NVIDIA card. The Intel card's base clock of 2100 MHz is higher than the NVIDIA card's 1740 MHz, and its boost clock of 2400 MHz slightly exceeds the 2377 MHz of the RTX PRO 5000 Blackwell. The Arc B770 also has a smaller die at 368 mm² compared to 750 mm², which may indicate lower manufacturing complexity per unit area.

The Arc B770's Xe2-HPG architecture and Battlemage generation represent a newer release timeline, with its release date listed later than the RTX PRO 5000 Blackwell. Its predecessor is Alchemist, marking a generational step within Intel's Arc lineup. The RTX PRO 5000 Blackwell's predecessor is Workstation Ada, positioning it within NVIDIA's professional workstation line.

For workloads that demand maximum compute throughput, memory capacity, and AI acceleration, the recorded data clearly favors the RTX PRO 5000 Blackwell. Its benchmark scores and 98th percentile rank demonstrate top-tier performance. For scenarios where power draw and PSU requirements are the primary constraints, the Arc B770's lower TDP and smaller suggested power supply make it the less demanding option, though its median percentile rank indicates a substantially lower performance ceiling.
